It had been a week since Kelly last reconnected with the wolf-girl Kate.

"That imp of a Kelly's gotten his claws into a werewolf beastkin now, heh..."

"You wouldn't dare call him an imp; at least say 'wimp'!"

"Truth be told, I thought that city boy had finally found a man."

"Hear me out though—my husband says some esteemed monk gave him enlightenment!"

"And isn't there talk about how he's been so sore from that one-time thrust in Helze Boar that he can't even get hard now?"

The idle chatter among bull ogre women tends to be shockingly candid.

Unaware of such rumors, Kelly lived out his days blissfully content.

"Mmmph... go-go..."

"Kyuu... You're sleeping so soundly, Brother Kelly. It's morning already..."

Kate licked Kelly's cheeks diligently while he remained unmoving. Amused by his failure to wake up, she gently peeled back the cloth covering his face.

There, beneath it all: Kelly's violently rigid erection had greeted the dawn.

"Aha!"

After a moment of sheer awe at his impressive display, she grabbed it with both hands and licked underneath the glans.

Still no sign of waking.

"...Brother Kelly, it's morning already. Morning! Time for me to get my fill again... ♪"

She whispered in an indistinct murmur—not quite sure whether she wanted to wake him or not—rubbed her cheek against his stiffening member before slowly pulling away her waist cloth. She wasn't wearing underwear; frankly, she had no intention of putting any on anymore.

"You're the one doing this by staying asleep... ♪"

With both hands, she spread her labia to their utmost limits and allowed herself to be skewered directly onto his cock. Though the size difference was painfully obvious, her expression remained undeniably joyful throughout.

"Mmphh... go-go... goo??"

"Ah... you're awake...?"

When half of his shaft—meaning Kate's entire depth had been reached by the glans—heavy-lidded Kelly finally opened his eyes.

What he saw was only her lower half uncovered, sitting atop his morning erection like it were some sort of playground equipment, swaying gently with every movement as she smiled warmly.

"Oh... wha—what?"

"Good morning, brother! Today too, I'm going to make a lot of mess for your cock... ♪"

"...Oh, come on. Didn't we do this from dawn until dusk yesterday too?"

"My tummy's hungry. No matter how many times you stuff me before sunrise, my stomach still grumbles by morning, right?"

"I—I mean... if you're hungry, go ask mom!"

"Not your 'tummy,' dummy! Your 'vaginal cavity'!"

Kelly slumped in defeat.

"...You've got some weird jokes there. Who the hell taught you that kind of stuff?"

"Mrs. Dorothy's killer humor move!"

His head throbbed at his mother's boundless generosity.

A quick glance toward the doorway revealed just a corner of her horn peeking out. Noticing she was being stared at, she left behind not a thumbs-up but rather her signature thumb-squeeze gesture before retreating inside.

"Mom... no matter how much you want grandchildren..."

"I'm going to make them! Gonna crank 'em out like clockwork! Come on, brother, let's get this grandkid production party started first thing in the morning. Sounds great for your health!"

"You're hopeless."

Kate waved her hands energetically forward and backward. While she could manage inserting on her own, piston-like motions were still beyond her reach.
So what she was gesturing was basically: "Grab my body sooner and start up-and-down thrusting immediately!"

"Once it's inside, there's no way to hold back..."

"It'll come out! I'm full of spawn from this morning too, so I'm feeling great, too! ♪"

"I have no idea what you're talking about..."

Kelly, unable to resist, begins ravaging Kate as requested. Kate wags her tail with an innocent smile, while the Isaacs were already thoroughly wrecked long before midday.

Wake up in the morning, fuck Kate, play with the kids, fuck Kate again, go fishing or hunting now and then, fuck Kate once more, hold court with buddies for a drink session, fucked out by the time you fuck Kate again one last time, take a bath and fuck Kate before bedtime, fall asleep while fucking Kate at night.

"What kind of life is this, man?"

"That's what every wolf beastfolk new couple does, right?"

Kate looks puzzled.

"Even those bull ogre hot couples are just like that."
Dorothy nods solemnly.

"But isn't that bad for the kids' education?"

"I'm actually wishing I'd provided even worse upbringing."
The current holder of the all-time virgin record among bull ogre colony males, he can't even make a guttural sound.

"Y-you know... I need to return to Basson in about two weeks, and getting used to this stuff isn't good."

"Don't quit the military."

"But you could stay here, right? I'll go to Basson! Wolf beastfolk, promise. Absolutely. I'll become your wife, for sure. Let's stop drifting apart, okay?"

"Hmm... Even if you say that, there aren't women in the barracks..."
Recalling that about one guy was dragged in, he gets a bit gloomy. While not as bad as Anzeros, Kelly is actually quite strict about discipline.

Or rather, in Kelly's case, it's just because the barracks have almost no contact with women, so he starts feeling more at home in that schoolboy-like atmosphere.

"It'll be fine, don't worry, we can figure something out."

"It'll be fine, don't worry, I got this! ♪"

"No way! ♪"

Pachin! Dorothy and Kate high-five, their height difference nearly sixty centimeters. Since a mother-in-law problem seems unlikely, it's slightly reassuring. However, unexpectedly serious Kelly is now scratching his head over what to do next.

Marriage to Kate is fine; I'll take responsibility. I've already made up my mind.
The real issue is whether to continue or quit. Still, he doesn't want to leave the military yet. He wanted at least to keep an eye on things until someone like Arnie got promoted to regular soldier.

Kelly wanders through the evening maze with his thoughts drifting aimlessly.
In his hand is a greatsword forged by dwarves, made of desert steel. To a normal human, it's practically impossible to lift, but from Kelly's massive frame, it's just an ordinary medium sword.
It belonged to his father. Perfect for hunting the hell boars.
Yes.

"Corporal Kelly Isaac... uh, Squad Leader Isaac?"

"Huh?"

From a corner of the maze, a shadowy figure appeared with a swish.

The atmosphere was tense, though no immediate killing intent radiated from them. Despite having his guard down somewhat emotionally, Kelly only gave her a leisurely glance, letting his head rotate slowly.
Light armor and a cloak. A longsword drawn at his waist. A dignified gaze swinging gently with her tied-up hair flowing freely.

At first glance, it's clear she's not a native of this desert maze right now. She's a soldier.

"Who are you?"

"I'm Squad Leader Linne Mikagami from the Western Legion's Third Infantry Regiment."

"Western Legion's Third Infantry... 'Mikagami,' like that old man Zenka?"

"Yes. I'm his granddaughter. Been a long time since we last met."

The Western Legion's Third Infantry Regiment is known as an elite force. Since they're constantly clashing with the current biggest threat, the Afilum Empire, in minor skirmishes, they have abundant combat experience and are especially noted for having a high ratio of ace knights among their ranks.

And the distinctive surname Mikagami appears in this dungeon only among wolf-beastkin. As expected, Zen'ga Mikagami's granddaughter was none other than one of Kate's sisters.

Yet that foreign, unsettling aura that Kate seemed to project is absent in her sister. She speaks standard Japanese with ease and familiarity.

"Have you heard anything about my younger sister?"

"Yes."

"As I thought... that's why I was looking for you."

"I've heard the rumor."

"...Are you still insisting she be your wife?"

"Yes."

"..."

Lynne shook her head, looking troubled.

"That girl has a tendency to get things stuck in her head."

"...What? Could it be that...?"

A thought suddenly surfaced—a possibility he had once considered.

Perhaps she was mistaken, believing in a promise she never actually made.

Lynne smiled softly.

"Don't worry. The promise is real. It's an absolute vow for both of us."

"..."

"But speaking with these lips of absolutes, I have one urgent request."

"?"

"I'd like you to void it."

While Kate spent some time basking in the sunlight, Kelly headed out on a hunt.
After feeling lonely and sulking dramatically, Kate ultimately couldn't muster the energy to continue pouting for even ten minutes and chased after Kelly into the dungeon.
Chasing after Kelly's scent until she caught the familiar aroma—more precisely, the smell of someone she had parted with only about ten days prior—she reflexively hid herself.
An older sister was there.
The sister stood facing Kelly quietly.

"Wolf-beastkin hold their promises above all else. They are a race that would dedicate their entire lives to fulfilling a vow, or even gouge out their own eyes and ears to keep one. Undoubtedly a virtue, but precisely because it's such an irrefutable virtue, they don't hesitate to sacrifice their own hearts and happiness in its name."

"..."

"That child made promises too big for her age. So consumed by the desire to honor the vow of becoming your wife that she's reached this point without ever knowing what it means to be in love."

"In love... doesn't know?"

As he spoke, it struck him—Kate had clung to Kelly almost religiously. It felt less like love and more like literal faith.

"I want my sister to understand what it is to fall in love with someone. Rather than serving someone until she burns out for the sake of a promise, I want her to experience the ordinary process of learning to love someone normally. I want my sister to have a rich life."

"...I see... If that's the case, there's nothing I can do about it, huh?"

Kelly dropped the line with good grace, as expected of him.

Yet he didn't anticipate that speaking such reasonable words would force him to taste blood in his heart once again.

(Here we go again...)

It was true that blind faith in Kelly wouldn't be Kate's greatest happiness.

But now that it seemed he might finally have to let go of the woman he thought he could reach, who he had convinced himself belonged to him, this time his vision would go completely dark.

"I assumed you'd say something like that."

Lynne nodded with a face so repulsively assured, squeezing those words out.

"You know. That girl is so stubbornly devoted... there's something cute about it, you could say..."

Kelly hadn't heard Linné's words. She didn't want to hear them. Another round of seclusion and weeping seemed inevitable; she felt utterly self-loathing, even wondering if she should quit the military too.

And precisely because she'd been so completely inattentive to Linné's speech, she had arrived just in time.

"......!!"

The dungeon ceiling shuddered faintly. The air barely tensed; atmospheric pressure shifted. There was a presence of monsters—not merely a common Helzbore, but something far more powerful.

"Noooonooo!!"

There was not even a moment's hesitation. Thanks to never having diverted her focus from Linné for an instant, she had caught the fastest possible timing and hurled the greatsword behind Linné.

Kon!

"AAAAAHHH!!"

"What?!"

Linné's ears shot up in alarm as she spun around hastily. A colossal rock golem—twice the size of Kelly—was toppling over her backside.

"Nnnngghh......?!"

"You've been tailed. You must have cut corners repeatedly near Queenika's dungeon entrance and ended up here."

"Uh, yes..."

"It seems you stepped into the rock golem's perception range."

Kelly glanced sideways at Linné bracing herself and quietly gathered strength within her body.

Her usually dark-eyed gaze began to emit a golden luster. The fury born of unforgivable despair—the rage slumbering within Kelly, that of a bull ogre—was finally awakening once more after so long.

The rock golem rose back up.

It awkwardly but powerfully attempted to pull the sword embedded in its chest free.

"BMOOOOOOOOO!!"

While emitting a golden light from her eyes, Kelly released all her coiled energy in a single springing leap. She kicked off the high ceiling and drove the butt of the greatsword, still impaled in the rock golem's chest, downward with her full body weight.

The golem's broad chest split vertically. She caught the greatsword, which had spun through the air like a whirlwind, and brought its right leg down in one flat horizontal blow across the stone giant's thigh.

"!!!"

Perfectly executed—its upper thigh was cleaved cleanly in two.

As the rock golem lost balance, Kelly took no time waiting for it to fall. With that massive leg still intact, she spun-kicked while kicking up a gust of wind inside the dungeon.

"PHUUUOOOOO!!"

Zuuun!

The rock golem stumbled and crashed to the ground.

She then thrust the sword straight down with brute force, spearing it firmly into the earth above its head.

"W-wow... magnificent..."

"BMOOAARRRR!!"

"Lord Kelly?!"

Without stopping, Kelly swung her fist downward.

She delivered a kick.

She seized the broken leg of the golem and slammed it again.

Each strike literally shattered rock; before one could blink, the rock golem was disintegrated into a scattering pile of stone fragments.

The special latent ability of a bull ogre.
In a dungeon—that is, within an enclosed darkness—a bull ogre can dramatically elevate its combat prowess.

As a Hornless Ogre born under the shadow of darkness, the Bull Ogre—optimized as the king of the underground—gains its combat prowess doubled in peacetime within that very environment.

"Though even so, Bull Ogres are far too accustomed to peace; they've lost that hellfire rage unless they're seasoned enough fighters like I am. From childhood on, I hunted with my life at stake... which is why... damn it."

"So that's how it was, then?"

"That's why breaking through the Rock God Maze was nothing for me—it was their bread and butter scenario. Something a Trot-style exhibition match just wouldn't have allowed back then."

"…………"

"I remember now. You... back then..."

"Yes."

Linne had taken the Ace Knight Exam Kelly once challenged, sitting right beside him.

And then... surrounded by moving corpses and golems, he'd been on the very brink of death.

Seeing him about to perish, Kelly intervened to save Linne. It was a blatant rule violation that would have left Kelly disqualified in any honest assessment.

"While Kate chased you, I honed my own skills too. When I heard you could sneak into the Ace Knight Exam and decide to enter with pride, thinking I'd bring glory home... that's when you saved me."

"…………"

"Why did you give up on becoming an Ace Knight after that?"

"...If saving someone meant being disqualified, I figured I wasn't cut out for this."

Rules are rules—he knew full well.

Yet, if a similar situation arose again, Kelly would do the same thing. And so he did.

And then Kelly realized something... he'd aimed high due to outside influence, but deep down, he never craved the prestige of an Ace Knight. All he wanted was to protect his comrades. That was enough.

"I mean, all I need is to guard my comrades. A crossbow isn't perfect? It lets me reach allies from far away too. So I decided to work hard with the Crossbow Corps."

"...Is that so? I thought you and I would meet again... Next year I took the Ace Knight Exam myself, and this is where I stand now."

Embedded on the breastplate of her leather armor gleamed the insignia of an Ace Knight.

"And look at them, the Third Infantry Regiment from the West's elite troops. Quite impressive, don't you think?"

"I suppose I too went astray."

"…………?"

Linne stood before the kneeling Kelly and began to strip off her armor.

Though she wore long sleeves and floor-length chainmail underneath—completely adequate for modesty—Kelly felt a sudden, prickling discomfort and turned his gaze away slightly.

"I can't say we've abandoned our promise either; Kate wouldn't accept that."

"Huh? What do you mean?"

"For a wolf-beastkin, promises are absolute. To void one is only permissible because another, separate promise among wolf-beastkin demands it—that's the extent of it."

"Is that so?"

"Yes. So I ask you to make a new promise with me. Only then can I set Kate free."

"…………"

A profound sadness settled over him. If he simply nodded, his blissful time with Kate would be over.

For a fleeting second, he entertained the thought: "Maybe if I threw a tantrum now..." But shaking off that petty ego and reminding himself of what a cowardly yet sane and authentic Kelly really is, he silenced it all.

Whether knowing this or not, Linne smiled gently and wove her words slowly.

"Make me your wife, Kelly Isaac."

"…………Hah?"

"I've been waiting for our reunion since that day. I've kept nurturing my feelings for you deep in my heart ever since... This bond without rules, this is true love. Please make me your wife so that someday I can let that child experience these emotions too."

"...What on earth am I even supposed to say here?" Kelly's face went pale with confusion.

Then, something moving caught the corner of his vision. He fixed his gaze on it using the characteristic lateral vision unique to Bull Ogres.

It's Kate. She'd been hiding in the shadows until now.

Kate thrust her fist upward—a sign to go, go on, Kelly brother!

(…Is this okay?)

Confused by the unfolding situation, Kelly hesitated, his worry only deepening as Linne's eyes grew increasingly anxious and he panicked further.

"Would I not be lacking in some way?"

"…W-well…"

"Yes, don't worry about night anymore. I've trained my body to accept your member too. If you want, I can even show you proof right now."

"…………"

Ah, there it was. A cold sweat broke out on Kelly's brow. How could Linne stride forward with such a cool expression, her massive, bulging type still fully erect?

And then Kate made the same gesture again—hurry, hurry!

"…Alright!"

"Glad you got it...♪"

Linne kissed the inside of Kelly's large lips, burying her nose and mouth within them—just like Kate.

"The promise is now complete. With this…"

"Weee~!♪"

Suddenly, from behind, Kate tackled Linne with a loud bash! Startled, Kelly blinked in surprise.

"K-Kate?"

"Sister wants to be your bride too, Kelly brother!"

"N-No way! Kate, listen to me!"

"Nfu-fu-♪"

"I made the arrangement for us to become husband and wife with Kelly-sensei! Your promise is already void!"

"Oh, come on, sister... Bull Ogre colonies have plenty of wives. It's normal."

"E-Eh? Eh?"

"It's different from the Werewolf beastkin. They're monogamous. ...Sister's promise was contradictory to begin with, right?"

"Eh-Eee-eh!?"

"Oh, I see... that's what you meant!"

Werewolf beastkin seem to follow a strict one-husband-one-wife system.

Even though Celesta legally permits polygamy in theory, human society fundamentally adheres to monogamy.

Linne, having moved directly from the Werewolf colony to a human city, hadn't grasped this distinction at all.

"Nfu-fu-♪... Sister, same here! Plenty of Kelly brother's children!"

"...U-Un, y-yes, it seems I'll have no choice but..."

"H-Hey, Linne... if it serves no purpose, we can just pretend it never happened!"

"Kelly-sensei! With the Werewolf beastkin, promises are absolute! I've already made mine!"

"...Exactly. Since a promise was made, I shall be your wife... And besides, having become like this to match you..."

Linne shyly pulled down her armor skirt, stripping it away. Kate joined in, shedding her own as well.

Linne wasn't wearing underwear—she simply couldn't.

As expected, her massively thick erection jutting from her crotch made it impossible to wear anything underneath.

"...There's no choice but for you to become my wife."

"...A-Ah, yes..."

Usually, if someone rushed ahead with their own expansion and blamed it on another, one would be annoyed—but strangely, Kelly found himself unable to complain.

No, of course not.
The thought of having his own progeny pleaded from such an adorable pair of wolf sisters brought him as a male too much joy to even complain about it.

Kate pulled out the insertable dildo that was currently lodged in Linne's crotch with a mischievous grin, dragging it forcefully.

"♪"

"Aa-yaa... Aaa-ahh!?"

With a wet squelch, the gigantic artificial phallus appeared—up close, you could see a bull's face carved into its shaft.

"...Who on earth made this?"

"Older sister ♪"

"...Y-yes... I guess it's just like this..."

"...Aren't they cute?"

"But starting today, you won't need these anymore? Every single day and night, Big Brother Kelly will give you his dong?"

"...Hnnn...♪"

The opened vaginal walls trembled with visible pleasure.

"...Can I... go in yet?"

"Yes... um... since I've never had experience before... if possible, please be gentle."

"...I've only done it with Kate myself, and I'm still a virgin cutting just over a week ago."

"Really ♪?"

Amidst the delighted gaze of Kate, Kelly's massive appendage was shoved deep inside Linne.

Given that he was slightly larger than Kate, Linne managed to take in a fair portion of Kelly's cock, swallowing it quite deeply—but even so, not all of it fit.

Still, Linne was drunk on the bliss of her inner vaginal walls being pressed upward by raw, hot flesh.

"Aa-ahh...♪ T-this is... Kelly-san's... penis...♪"

"Dong ♪"

"U-uuhh... Kate, that's embarrassing to say like that."

"The dong is the dong, isn't it?"

"But..."

"I get a little more excited when you call it a dong too."

"...O-okay, ...d-dong."

"Do it again."

"Dong... Dong... Kelly-san's... bull dong...！！"

"Ho. Good one."

"Dong... dong, good... give me even more donging... with your dong, pound me lots and lots of times... A-aha... y'know, calling it a 'dong' in such a vulgar way... makes it even better...♪"

After being told to say it a few times, Linne had completely adopted Kate's direct style.

Her flushed cheeks glistened as she slowly moved her body up and down, twitching her tail vigorously to show how much pleasure she felt. Thanks to the strengthening exercises with the insertable dildo, there was no pain—but that overwhelming sense of vital life made her sink deeper into it moment by moment.

Rational and intellectual Linne, once started sliding down this path, gave in all too quickly. No wonder; like Kate, she was young enough to adapt rapidly.

"Haa... haa, Kelly-san, more... more, pound me harder... I'm so frustrated, break me down more, make me useless with your dong ♪"

"Oh, ohh... Here we go."

He wrapped both hands around her, gripping Linne tightly. Instantly understanding what was about to happen, Linne's eyes gleamed with anticipation.

"...♪♪"

Shhk, shhk, shhhk...!!

Gripping Linne's body in small, forceful motions, Kelly began working his appendage within her vagina. Due to their significant size difference, if he tried to move too quickly or risk being pulled out completely, he had no choice but to make her do the work instead.

Lynne, gripped by the body and treated like a gaping hole made only to clamp down on an appendage, tasted an unparalleled pleasure in her humiliation. She had utterly denied her strong identity as an Ace Knight, deriving an intense state of rapture from being handled merely as a woman, a mere device for pleasure.

"Aa, h, ahh! Good, this is good... waa, ahuuu, ah!!"

"Here we go... here we go, Lynne, I'm going to cum...!?"

"Ahuu♪... Yes, w-wat-, me... sperm, inside of me... semen, fill it up, soak me... I'm pregnant♪"

"U, ku, uuu...!!"

"Aaaaaaaahhh!!!"

He thrusts it in deep, releasing his seed into the depths of Lynne.

Though the sisters bore atmospheres far from similar, their vaginas were akin and both welcomed Kelly's deluge of semen with equal pleasure.

Shuddering, they sucked up the cloudy white fluid into their wombs; the overflow bubbling forth was licked away with gusto by Kate, slurping it down as if it were delicious.

"Ha...♪"

"Nn, nn, Leil-... It's too precious to waste...♪"

"W-well, if you get that worked up just like this, won't we both want to fuck again? Nobody knows who's passing through around here!"

"I'll do it, use my dick! After the older sister, it's my turn!"

"...Damn, there's no bottom to this thing, is there, ya know?"

◇◇◇

Lynne Mikagami. Height 159cm, Wolf beastkin. Age 19.
Passed the Ace Knight examinations four years ago and was recruited. Currently serving as Squad Leader of the Third Infantry Battalion, Western Legion.
While renowned for her high-speed swordsmanship and martial arts, possessing a fighting instinct that leaves onlookers stunned in times of crisis, there is also an assessment that she has begun to harbor doubts about her legs and feet lately.
A few days ago, she submitted a transfer request to the Northern Legion's "Second Crossbow Corps." At present, no records of such a unit can be found in official documents; since the Crossbow Corps lies outside the active combat roster, her application is on hold pending review.
Suspicion also exists that she may have been unable to endure the heavy responsibility of Squad Leader due to her still-youthful age. When hinted at a demotion, she readily accepted it.
For these reasons, upon the Crossbow Corps' reinstatement, she is slated for assignment as a guard infantryman treated as regular combatant status.
Final confirmation requested by Central Command.

◇◇◇

In the command center, the Sixth Minister pulled a sour face.

"...It seems strange lately that the women-to-men ratio in Diane's unit has gone up significantly. I thought the guideline there was to organize with men only, didn't you?"

"Oh, come to think of it, do you know what's going on, Minister? It sounds like Squad Leader Diane has gotten a boyfriend or something."

"Uh, uh, regarding that matter... I suspect some kind of misunderstanding or confusion, but it came back without being clearly clarified. What is happening here?"

"There's a rumor about a man. Apparently, he's rumored to be an absolute womanizer. For some reason, reports from Special Squad Leader Becker claim he's picking up lots of demi-humans or something like that."

"Ugh, this bastard's doing again!"

He wasn't.

(TBC)

A week had passed since Kelly reunited with the wolf-girl, Kate.
"Oh, look at this—our little Imp of a Kelly actually got hooked on a wolf beastman..."
"Cut it out and stop calling him an 'Imp.' At least give him the title of 'Coward.'"
"I thought he'd just discovered he was a man while living in the city, you know."
"Heard from my husband that some high-up priest gave him an enlightenment experience or something."
"Hadn't I heard stories that he couldn't get hard anymore since he got his balls skewered by a Hellboar?"
The bull ogre women’s idle chatter was rather explicit.

Unaware of any such gossip, Kelly had been spending every day in blissful ignorance.

"Mmph... grrr..."

"Coo... you've slept well. Big Brother Kelly, it's morning..."

Kate licked Kelly's cheek with a pe-ro-pan, while Kelly failed to wake up.

Smiling contentedly at his refusal to rise, Kate gently pulled back the coverlet draped over him.

Kelly’s violent virility was in good morning form.

"Ah-ha!"

Dazzled for a moment by the sight of that magnificent warrior, Kate grabbed it with both hands and licked the underside of the glans with her tongue. Kelly still wouldn't wake up.

"...Big Brother Kelly, it's morning-oh. Morning-oh. It's time to do me again... ♪"

Whispering in a small voice that made it unclear whether she wanted to wake him or not, Kate rubbed his cheek against his morning erection, then slowly undid her loincloth. She wasn't wearing underwear anymore. She had no intention of ever putting any on again.

"It's bad of Big Brother to keep sleeping... ♪"

Then, rolling the labia open as far as they would go with both hands, she impaled herself onto Kelly’s meat rod. Despite the painful size difference, her expression was purely one of enjoyment.

"Mmp... grrr... grrr... eh?"

"Oh, did you wake up..."

Just as the glans reached the bottom of Kate's depths—meaning half the length of the meat rod—Kelly slowly opened his heavy-lidded eyes.

What reflected in his gaze was the figure of the wolf-girl, having removed only her lower garments, sitting astride his morning erection and swaying her hips back and forth as if using his member like a playground toy, smiling down at him.

"W-what? What's going on?"

"Good morning, Big Brother. We're gonna do you all day today too~ ♪"

"N-n-no way. You did me over and over from dawn till dusk yesterday."

"I'm hungry~. No matter how much I ate the day before, I'm always hungry in the morning, right?"

"N-no, if you're hungry, ask Mom."

"It's not my tummy? It's my insides, right?"

Kelly slumped, defeated.

"...You've picked up some weird jokes. Who did they pump you with that nonsense?"

"Dorothy Auntie’s signature humor," she said, referring to her mother's legendary wit.

Kelly’s head throbbed at his mother’s sheer boldness.

Glancing toward the doorway, he saw the tip of his mother’s horn peeking in. Noticing they were being watched, she flashed a thumbs-up—or rather, a thumb-between-the-fingers sign—and retreated.

"Mom... no matter how much you want grandchildren,"

"We're gonna make 'em~ We'll make them hard and fast. Here here, Big Brother, let's seed a grandchild first thing in the morning. It's definitely good for your health."

"You really..."

Kate flapped both her hands forward and wiggled them. She could manage the insertion on her own, but she wasn't yet capable of doing the pistoning motion herself.

So the gesture was essentially asking him to grab hold of her hips and piston her up and down.

"Once I put it in, there's no way I'm just pulling out..."
"I'll do it~. I've been shooting plenty of seed into you since this morning too, so I'm feeling great~♪"
"I have no idea what the hell you're talking about..."
Kelly started fucking Kate as she demanded. Kate wagged her tail with an innocent smile. The Isaac household was thoroughly debauched long before the sun even reached its zenith at midday.

Wake up in the morning, fuck Kate, play with the kids, fuck Kate, go fishing or hunting occasionally, fuck Kate, drink beer with the guys, get drunk and fuck Kate, purify his body at the water source before bed while fucking Kate, and fall asleep at night while fucking Kate.

"What kind of life is this for me?"

"Wolf beast-people all live like that when they're newlyweds, don't they?"

Kate looked puzzled.

"Even the bull ogres have couples who are hot and heavy just like that."

Dorothy nodded gravely.

"Isn't that bad for raising kids?"

"I was regretting that I should have given even worse education."

She is a virgin record holder in a colony of bull ogres who couldn't let out a single sound.

"But... look... I have to go back to Basson in about two weeks, so it's not good to get used to this."

"Just quit the military already."

"Or you could just come along? I'll go to Basson? Wolf beast-man, promise me. Absolutely. I'm becoming your brother's wife, absolutely. No more being apart?"

"Mm... even if I say that, having a woman in the barracks..."

He recalled a certain man who brought someone back with him and felt a bit depressed. Kelly wasn't as strict as Anzeros regarding discipline, but she was quite a moralist when it came to such things.

Rather, in Kelly's case, she just felt comfortable in the barracks because there were almost no female contacts there.

"It'll be fine, fine, you'll manage somehow."

"It'll be fine, fine, I'll manage~♪"

"Mm~♪"

Pachi! Dorothy and Kate, who had a height difference of nearly sixty centimeters, high-fived. It was a reassuring sight because the mother-in-law problem didn't seem likely to arise, but Kelly, who was unexpectedly serious about such matters, rubbed her head in worry over what to do next.

Marrying Kate was good. He would take responsibility. His mind was made up.

The only issue left was his own career path. Still, he didn't want to quit the military yet. At least he wanted to see it through until Arnie or someone like him became a Sergeant.

Kelly wandered leisurely through the afternoon labyrinth, lost in thought.

In his hand was a dwarf-crafted greatsword made of desert steel. For a human, it was a massive weapon barely possible to lift, but given Kelly's huge frame, it was about the size of an ordinary mid-sized sword.

It had been his father's keepsake. Perfect for hunting Hellswine.

And so on.

"Sergeant... I mean, Ten-Man Leader Kelly Isaac?"

"Hm?"

A figure swayed into view from the corner of the labyrinth.

The atmosphere was ominous, but he didn't immediately sense any murderous intent directed at him. Although his mind prepared for a fight out of instinct, Kelly looked around casually with an outwardly relaxed demeanor.

Light armor and a cape. A longsword at her waist. A woman with hair tied up loosely swaying, possessing a sharp, noble gaze.

At a glance, it was clear she was not a current resident of the Desert Labyrinth. She was a soldier.

"Who are you?"

"I am Ten-Man Leader Rinne Mikagami, attached to the Third Infantry Squad of the Western Legion."

"The Western Legion's Third Infantry... Mikagami is that Zenga Old Man's family name."

"Yes. I am his granddaughter. You must know of me by now."

The Western Legion's Third Infantry Squad was known as an elite unit. Because they repeatedly engaged in skirmishes with the Empire of Afirul, which was currently the greatest threat, they were renowned for their extensive combat experience and particularly high ratio of Ace Knights.

The surname Mikagami was distinctive, found exclusively among the wolf-beastkin in this labyrinth. As expected, she was one of Zein Mikagami’s grandchildren—meaning one of Kate’s sisters.

Yet Kate did not possess the foreign, unstable air that clung to her sister. She was quite accustomed to the standard dialect.

"Do you have any idea about my younger sister?"

"I do."

"Indeed... We had been looking for you."

"Heard it all."

"...Is she still insisting that she will become your wife?"

"Aye."

"..."

Lynne shook her head with an air of concern.

"That girl has a hell of a tendency to overthink things."

"...What? Could it be that..."

A thought suddenly struck him, recalling a possibility he had once entertained.

Perhaps...

He wondered if she might be misinterpreting a promise that had never even been made.

Lynne offered a faint smile.

"Rest assured. A promise was made. It is absolute for us."

"...So it seems."

"But with this very tongue that speaks of absolutes, I dare to make a request."

"?"

"I want you to go back on it."

While Kate spent some time sunbathing, Kelly had gone out hunting.
Feeling lonely, Kate threw a petulant, kyu-kyu tantrum, but she couldn't keep up the sulking for even ten minutes before chasing after Kelly and plunging into the labyrinth.
As she ran, tracking Kelly's scent, she caught a familiar smell—or rather, the scent of someone she had parted with just ten days ago. Reflexively, she hid.
Her sister was there.
Her sister stood quietly confronting Kelly.

"Wolf-beastkin value their promises highly. We are a race that would devote their entire lives to a promise, or even gouge out our own eyes and tear off our ears if necessary. It is indeed a virtue, but because it is an impeccable one, we question not even sacrificing our hearts or our happiness for it."

"..."

"That girl made too large a promise when she was young. So eager to keep the vow of becoming your wife, she has come this far without ever knowing what love is."

"Loves... doesn't know?"

Now that Lynne mentioned it, Kate had clung to Kelly with a slightly fanatical intensity. It felt less like love and more like literal faith.

"I want my sister to know what it means to fall in love with someone. I want her to know the process of simply liking someone, rather than devoting herself until she drops for the sake of a promise. I want my sister to lead a rich life."

"...I see. ...Well, if that's how it is, then I suppose we've got no choice, huh?"

Kelly let out a remark that was far too understanding.

As he spoke those easy-to-understand words, he hadn't expected that he would once again have to taste the feeling of spitting blood in his heart.

(...Here we go again.)

Honestly, he didn't think that blindly following Kelly was the greatest happiness for Kate.

But at the thought that he might be forced to let go of a woman he had believed was within reach—a woman he had convinced himself was—his vision went completely dark this time.

"I figured it would come down to that."

To Lynne, who nodded with an infuriatingly relieved expression, those were words squeezed out through gritted teeth.

"Probably. That girl is a bit too single-minded, and while that's what makes her endearing..."

Kelly didn't hear Rinne's words. She didn't want to. She figured she'd just withdraw to some corner again and cry. The self-destructive mood was rising: maybe she should just quit the military altogether.

And because she hadn't been listening to a single word of what Rinne had said, she made it in time.

"……!!"

The ceiling of the dungeon trembled faintly.

The air warped slightly. The atmospheric pressure shifted.

A monster's presence. Not something on the level of a hellboar, but something far more powerful.

"Muuuuuugah!!"

There was not an instant of hesitation. Because she hadn't spared even a second's attention to her conversation with Rinne, she didn't miss the most optimal moment, and threw her greatsword behind Rinne.

Goon!

"Ooooooooh!"

"Huh!?"

Rinne perked up, her ears twitching as she hastily turned around. A giant rock golem, twice Kelly's size, was falling right behind her.

"W-what...!?"

"You've been tailing us. I assume you shortcut here from the dungeon entrance near Queika."

"H-hai..." (Yes...)

"Looks like you stepped into the rock golem's perception range."

As she took a defensive stance beside Rinne, Kelly quietly gathered strength within her body.

Kelly's normally dark eyes radiated a golden brilliance. Anger—anger born from transforming helplessness and despair—was about to awaken, for the first time in a long while, the raw power of the Bull Ogre sleeping within Kelly.

The rock golem got back up.

It tried to rip the sword stuck in its chest out with an awkward yet powerful motion.

"Bumooooooh!!"

Golden light burst from her eyes as Kelly released the springs throughout her body, leaping into a single jump. She kicked the high ceiling, then brought down her full weight on the hilt of the sword impaled in the golem's chest.

The golem's ribcage split vertically. Snatching the greatsword as it spun through the air, she caught it mid-flight and slashed horizontally through the golem's right leg.

"!!!"

Perfectly severed at the thigh. It was split cleanly in two.

The rock golem lost its balance. There was no need to wait for it to fall. Using that thick leg as a pivot, Kelly spun around and delivered a roundhouse kick, stirring up the wind of the dungeon.

"Fuooooooh!!"

Thud!

The rock golem tumbled and collapsed.

She slammed the sword down into its head with sheer force, pinning it to the ground.

"N-nice work..."

"Bumoooaaah!!"

"Captain Kelly!?"

Kelly continued by swinging her fist down.

She kicked.

She grabbed the golem's broken leg and smashed it to the ground.

Each of those blows literally shattered the stone, and before their eyes, the rock golem was dismantled into a pile of rubble.

The special latent ability of the Bull Ogre.
In a dungeon—that is, in enclosed darkness—the Bull Ogre can dramatically increase its combat power.

Born as rulers of the darkness, Ogres are formidable, and among them, Bull Ogres are optimized to be kings of the earth. In such an environment, their offensive capabilities double what they are in peacetime.

"However, it’s said that because Bull Ogres got too used to peace, they’ve become quite bad at fighting, so this kind of desperate strength is no longer common. I did life-or-death hunts since I was a child, so before I knew it…… that’s how it turned out."

"So that was the case."

"That’s why clearing the Rock God Labyrinth was a piece of cake for me. It was Bull Ogre home turf after all. They couldn’t have done it in those formal spars at Trot’s place."

"…………"

"I remember now. You, back then……"

"Yes."

Linne had taken the Ace Knight exam together with Kelly when he once challenged it.

And…… surrounded by animated corpses and rock golems, she had been on the verge of death.

Kelly, seeing how bad things were, stepped in to save Linne. It was a rule violation, and as a result, Kelly was disqualified.

"Chasing after Katie sharpened my skills quite a bit. When I heard I could join the Ace Knight exam on a drop-in basis, I got cocky thinking I’d bring honor back to our hometown, so I signed up…… and that’s when you helped me out."

"…………"

"Why did you give up on becoming an Ace Knight after that?"

"……If helping people just gets you disqualified like that, I figured I’m not cut out for it."

Rules are rules. He knew that.

But if he faced a similar situation again, Kelly would do the same thing. And the outcome would be the same.

And Kelly realized it. ……He had been pushed by others to aim for it, but deep down, he didn’t actually want the prestige of being an Ace Knight. As long as he could help his comrades, that was enough.

"Besides, I just need to be able to protect my friends. A crossbow is perfect for that, right? You can even help teammates who are really far away. So I decided to give it my all in the Crossbow Corps."

"……I see. I had assumed we would meet again…… I took the Ace Knight exam the following year as well, and now you can see how it turned out."

An Ace Knight badge was embedded in the chest of her leather armor.

"And into the elite Third Western Infantry Regiment. Not bad at all."

"Thinking back, I must have taken a wrong turn too."

"…………?"

Linne stood before the seated Kelly and began to remove her armor.

She was wearing a long-sleeved, full-length undersuit, so there wasn't an issue, but Kelly felt it was a bit improper and looked away.

"Even if you try to break your promise, Katie wouldn’t accept it."

"Hm? E-what do you mean?"

"Wolf-beast promises are absolute. The only thing that can void such a promise is a contradiction with another wolf-beast's promise."

"So that’s how it is?"

"Yes. So please make a new promise with me. That way, you can set Katie free."

"…………"

Kelly felt very lonely. If he just said "yes" now, his honeymoon period with Katie would be over.

For a split second, a thought crossed his mind: maybe if I throw a tantrum right now, it’s still not too late? But Kelly the cowardly, calm, real Kelly talked himself out of such selfishness.

Knowing or not knowing of Kelly's lonely inner struggle, Linne smiled and spoke slowly.

"Please make me your wife, Kelly Isaac."

"…………Huh?"

"I’ve been waiting for this reunion since then. I kept my feelings for you warm deep in my heart all this time. ……I think this is a bond without promise, true love. So that one day I can let that child experience these same feelings, please make me your wife."

"…………"

The point of contention was slightly unclear. Kelly went pale.

Just then, Kelly noticed something moving in the corner of his eye and focused on its movement using the peripheral vision unique to Bull Ogres.

It was Kate. She had been hiding in the shadows until now.

Kate thrust her fist upward. Go, go ahead, Brother Kery, was the signal.

(...Is this okay?)

Struggling to keep up with the incomprehensible developments, Kery agonized over what to do. As Rinne’s gaze grew increasingly uneasy, he only became more flustered.

"Am I... lacking as a wife?"

"...I-I mean, it's just that..."

"Ah, if you're worried about last night, there's no need to be. I have been training myself so that I can accept your manhood. If you wish, I can prove it to you right now."

"......"

Kery broke out in a cold sweat. That thing. While keeping such a cool expression, Rinne had presumably been walking around with the extra-large support structure still inserted.

And then Kate made the same gesture again. Hurry up, hurry up.

"...I get it."

"Glad you do... ♪"

Rinne pressed her nose and mouth into Kery's large lips in a kiss, just like Kate had.

"The agreement is now complete. And with this..."

"Yay! ♪"

From behind, Kate pounced on Rinne with a thump. It startled them both.

"K-Kate?"

"Big sister will be Brother Kery's wife too!"

"N-No! Listen to me, Kate!"

"Mmmfufu~ ♪"

"I have established the promise to become a husband and wife with Mr. Kery, so Kate, your promise is already..."

"You know, big sister. ...In a Bull Ogre colony, it's normal for a man to have many wives."

"...H-Huh?"

"It's different from the Wolf Beastmen. ...Big sister's promise, no contradiction made?"

"Eh? What!?"

"Ahh, I see. That's what it is."

It seemed the Wolf Beastmen practiced strict monogamy.

And although in Celesta polygyny was recognized by law, human society fundamentally upheld monogamy as the norm.

Rinne, who had moved directly from a Wolf Beastman colony to a human town, hadn't fully grasped that distinction.

"Mmmfufu~ ♪ ...Big sister, together! Lots of children with Brother Kery!"

"...Mm, so it's come to this... I see."

"U-Um, Rinne... if it means nothing, we can just say it never happened..."

"Brother Kery. Wolf Beastman promises are absolute. I've already made the promise."

"...That's right. Since I have made a promise, I will become your wife. ...Besides, having become like this to match you, I am..."

Rinne shyly undressed her lower armor. Kate did the same to join in.

Rinne was not wearing underwear. She couldn't wear any.

The extra-large support structure was still lodged between her legs, just as expected.

"...So there's no choice but for me to become your wife."

"...Ah, I see..."

Usually, if one's body had undergone spontaneous self-expansion and one were blamed for it by others, they would find it troublesome, but surprisingly, Kery didn't feel like complaining about it at all.

No, naturally not.
The joy of the male, aware that he was being coerced into taking this utterly endearing wolf sister as his mate, left him no room for such objections.

Kait pulled out the molding from Rinne's crotch with a forceful, amused expression.

“♪”

“Ahh, don’t... Aah, ahh!?”

Gurrrr. The enormous artificial member revealed itself. Looking closely, one could see a cow’s face carved into it.

“...Who made this?”

“My big sis ♪”

“...Yes, yes... I just... ended up with something like this...”

“...Ain’t that cute?”

“But I don’t need this starting today? Every day, every night, Brother Kellie gives me his dick, right?”

“Nn... ♪”

It was clearly visible that her open vagina was trembling in pleasure.

“...C-Can I put it in?”

“Yes... Th-That is, I have no experience... So, please be gentle if possible.”

“...I’ve only done this with Kait too, and I just lost my virginity a week ago.”

“Yeah ♪”

Under Kait’s delighted watchful eyes, Kellie’s prized possession was thrust into Rinne.

Though her body was slightly larger than Kait’s, she swallowed Kellie’s meaty stick somewhat deeply, but of course, not all of it.

Even so, Rinne was intoxicated with the pleasure of the raw, hot member pressing against the deepest part of her womb.

“Ahh, ahhh... ♪ Th-This is, Brother Kellie’s, manhood... ♪”

“Dick ♪”

“U-Ugh... Kait, that’s embarrassing, don’t say it like that.”

“It’s dick, so it’s dick, right?”

“But...”

“I get a little more excited if you call it a dick too.”

“...I-I understand... D-Dick.”

“One more time.”

“Dick. ...Dick... Brother Kellie’s, Cow Dick...!!”

“Wooow. Nice.”

“Dick... Dick is good... Give me more dick... Stuff me with your dick, poke me in and out a lot... Aah, ahaha, you’re right, calling it a dick is actually better... ♪”

After being made to say it several times, Rinne was fully assimilated into Kait’s direct style.

With her cheeks flushed red, she moved her body up and down slowly, wagging her tail to express how pleasant it felt. Thanks to the training with the molding, there was no pain, but that overwhelming sense of vitality gradually stained her more and more with each moment.

Rinne had an intellectual image, but once she started breaking down, it happened quickly. Just like Kait, being young meant she adapted fast.

“Haa... Hah, Brother Kellie, more... Fill me up with more poke-poke... It’s frustrating, destroy me more, destroy me with your dick ♪”

“Y-Yeah... Here I come.”

Enveloping her with both hands, he gripped Rinne tightly. Rinne instantly understood what was about to happen and her eyes glazed over with anticipation.

“Nnn ♪♪”

Ji, ji, jii... !!

Kellie grabbed Rinne’s body in short, strong bursts and began to squeeze his prized possession in her vagina. Due to the large difference in build, he had no choice but to move the woman rather than himself, trying to keep the movements quick while controlling them so he didn’t pull out or go too deep.

And Linne, whose body was seized and treated as little more than a hole for him to stuff his cock into, tasted an unprecedented pleasure in her submission. Having utterly denied her former self as the strong Ace Knight, she found an intense euphoria in being handled as nothing more than a woman, a device for pleasure.

「Ah, haa... A-ah! Good, this is... good... Mmm, ah, uuuu!!」

"Here it comes... here it comes, Linne, I'm gonna cum...!"

"Ah, ooo♪... Yes, I, I am... I'll take it... my seed, inside me... Fill me up with your semen, pack me tight, marinate me... Make me pregnant♪"

"Ugh, nng, uuuu...!!"

"Aaaaaaah!!!"

He thrust in hard, ejaculating deep into Linne.

The sister's vagina, despite their differing personalities, enjoyed Kelly's torrent of semen just as the other did.

Her trembling womb drank in the whitened fluids, and the excess that bubbled out with wet squelching sounds was lapped up deliciously by Cait.

「Haa...♪」

"Mmm, mm, don't be so... wasteful...♪"

"I-I mean, don't go all in like that, ugh... Don't do stuff like that again or I'll end up wanting to fuck you again, and who knows who'll walk by a spot like this."

"Yeah, give it a ride on my dick. After big sister, me!"

"… Damn, you guys really have no bottom limit, huh, Oi?"

◇◇◇

Linne Mikagami. Height 159cm. Wolf-beastman. 19 years old.

Passed the Ace Knight exam four years ago and was hired. Served as a Ten-Man Unit Leader in the Third Infantry Company of the Western Legion.

Known for her high-speed swordsmanship and martial arts, her combat instincts were stunning when it came to actual battle, though there have been recent assessments noting concerns about her legs and lower back.

Submitted a transfer request a few days ago to the Northern Legion's "Second Crossbow Corps." Currently unable to verify the unit in documents; since the Crossbow Corps is off the strength list, the decision is on hold.

There are suspicions that she could no longer bear the heavy responsibilities of a Ten-Man Unit Leader due to her youth; when demotion was suggested, she accepted immediately.

For the above reasons, upon her return to the Crossbow Corps, she is scheduled to be assigned as a Guard Infantryman with the status of Regular Soldier.

Requesting final confirmation from the Central Command.

◇◇◇

The Sixth Minister scowled in the command center.

"...It feels like Diane's unit has had an unusually high increase in female soldiers lately. Wasn't there a guideline about not forming units with just men?"

"Ah, do you know that, Minister? I heard that Captain Diane got a boyfriend or something."

"Mm, hmm, about that matter... I sort of misinterpreted it and came back without things being very clear, but what was it again?"

"There's a rumor about the man in question. Apparently, he's incredibly womanizing. Reports from Chief Beaucher say he's been picking up a lot of sub-humans for some reason."

"Hmm, it must be his doing!"

It wasn't him.

(To Be Continued)

A week had passed since Kelly met the wolf girl Kate again.

"Who would have thought that Kelly, of all people, would end up with a werewolf..."

"Don't call her an impotent. At least say she's a coward."

"I always thought he'd only wake up to men in the city."

"My husband says he was enlightened by some great man."

"And I heard something about him not being able to get hard since that time he got stabbed in the balls by a Hellhound."

The gossip among the female ogres at the well was rather crude.

Unaware of such rumors, Kelly was living happily.

"Mngh... Gogogo..."

"Kyu-- You're sleeping so soundly. It's morning, Kelly..."

Kate licks Kelly's cheeks, but he doesn't wake up. Smiling smugly at his continued sleepiness, she gently pulls back the blanket covering him.
Kelly’s violent erection greets her in the morning.
“Aha!”
After admiring it for a moment, Kate catches hold of it with both hands and licks the underside of the head.
Kelly still doesn’t wake up.
“…Brother Kelly, it's morning—morning. It’s time to do me again—♪”
Whispering in an unclear voice whether she wants him awake or not, she rubs her cheek against his morning wood before slowly removing the waist cloth. He isn't wearing any underwear; he had no intention of putting them on.
“It’s your fault for still being asleep—♪”
Then with both hands, she spreads open Kelly's labia as far as they will go and impales herself onto his cock. The size difference is painful to look at, but her expression remains joyful.

「Ngh... Gog... Go... Uhn?」

「Ah, you’re awake...?」

When the tip of his cock reached deep inside Kate’s pussy, Kelly opened her heavy eyes. The sight that met them was a wolf girl who had only taken off her bottom half and was sitting on top of him, smiling as she moved her hips back and forth.

「Ohh... What is it?」

「Good morning brother. I’m gonna fuck you all day today♪」

「Hey, hey. Didn’t we do this yesterday from morning till night?」

「I’m hungry. No matter how much I eat the day before, my pussy gets hungry in the morning too?」

「N-no, if you’re hungry just tell your mom.」

「It’s not my stomach that’s hungry... It’s my pussy.」

Kerry slumps.

"...What a weird joke. Who put that in her head?"

"It's Aunt Dorothy's trademark humor."

The sheer audacity of her mother is giving Kerry a headache.

Glancing at the door, she sees her mother’s horns peeking out. Realizing she was being stared down by Kerry, she gives a thumbs up sign and retreats back inside.

"Mom... even if you want grandchildren so badly..."

"I'll make them! I’ll make lots of them! See brother, first thing in the morning I’m gonna give you a grandchild. It’s good for your health."

"You are something else."

Katie waves her hands in front of her, palms out. She can do it herself up to a point, but she still can’t manage the piston movement.

So she was gesturing that he should grab her and move her up and down.

“Once you put it in, there’s no way to take it out…!”

“I’ll take it out. I’m full of cum today too and feeling great♪”

“I have no idea what you’re talking about…”

Kerry starts fucking Kate as she demands, with an innocent smile on her face as she wags her tail. The Isaac household was already in a terrible state before noon.

When he woke up in the morning, he had sex with Kate, played with the kids, had more sex with Kate, went fishing or hunting sometimes, fucked Kate again, drank with his friends, got slightly drunk and had sex with Kate, cleaned himself at the water source while having sex with her just before bed, and slept through the night while fucking Kate.

“What kind of life is this?”

“Isn’t that how it goes for newlyweds who are lycanthropes?”

Kate looks puzzled.

“It’s the same for hot couples like us, even if we’re bull orcs.”

Dorothy nods solemnly.

"Isn't that bad for a kid's education?"

"I was just regretting not having given him an even worse one."

He’s the virgin record holder of the Ogres’ colony, unable to make a sound.

"But you know... I have to go back to Basson in two weeks. Getting used to this isn’t good either."

"Just quit the army then."

"You could come with me? I’m going to Basson too! Wolf-human, promise. For sure. I’ll be your bride, for sure. I don’t want us to be apart anymore?"

"Hmm... Even if you say that, there are no women in the barracks..."

He remembered that one person had brought a woman along and felt somewhat gloomy. While not as bad as Anzeros, Kelly was also quite strict about discipline.

Actually, it’s more like Kelly feels comfortable with the all-male environment of the barracks because he rarely interacts with women there.

"It’ll be okay, we’ll figure something out."

“Don’t worry, don’t worry, it’s all good~♪”

“Nope~♪”

Dorothy and Kate clapped hands in a high-five despite their height difference of nearly sixty centimeters. It was somewhat reassuring to see that there didn’t seem to be any mother-in-law issues arising, but I couldn’t help worrying about the future of serious Kelly.

It’s fine for me to marry Kate. I’ll take responsibility and have already made up my mind. But now it’s a matter of how to proceed. Still, I don’t want to leave the military just yet. At least, I wanted to stay until Ernie was promoted to full soldier.

Kelly walked through the maze-like streets in the evening while lost in thought.
In her hand was a large sword made by dwarves from desert steel. It would be difficult for an ordinary human to lift it, but to Kelly’s massive frame, it felt like a regular middle-sized sword.
It had belonged to my father and was perfect for hunting Hellboars.

And then,
“Kelly Isaac, Sergeant… or should I say Corporal?”

"Hmm?"

A figure appeared from the corner of the maze. The atmosphere was tense, but there wasn't any immediate hostility. Kelly remained on guard emotionally, though she looked relaxed as she turned her head.

She wore light armor and a cloak. A longsword hung at her waist. Her hair was tied up, and her sharp gaze was intimidating.

At first glance, it was clear that this person didn’t belong to the current desert maze population. She was a soldier.

"Who are you?"

"I'm Lynne Mikagami of the Third Infantry Regiment in the Western Army Corps," she replied.

"The Third Infantry Regiment in the West... Mikagami? You’re Zenka’s grandson, right?"

"Yes, I’m his granddaughter. It's been a long time."

The Third Infantry Regiment in the Western Army was known for being elite. They frequently clashed with the Afilum Empire, which was currently their greatest threat. As such, they were well-versed in combat and had many ace knights among them.

And the distinctive surname Mikagami was only seen among the wolf beastmen in this labyrinth. As expected, Zenga Mikagami's granddaughter, that is, one of Kate’s sisters.

However, unlike Kate, she didn’t have an unstable feeling of being foreign. She also handled standard language with ease.

"Do you know where my sister is?"

"Yes."

"As I thought... You were the one we were looking for."

"I heard."

"...Are you still claiming to be my wife?"

"Yeah."

"..."

Lynne shook her head in a troubled manner.

"That girl has a very strong imagination."

"...What? Could it be..."

Suddenly, she recalled the possibility that had once crossed her mind.

Maybe...

She wondered if perhaps she believed in an imaginary promise.

Lynne smiles.

"Please don't worry. We did make a promise. An absolute one for us."

"...I see."

"But I'd like to ask you something despite my saying it's absolute."

"??"

"I wish to break our agreement."

While Kate was basking in the sun for a bit, Kelly had gone hunting. Kate felt lonely and pouted for a while before chasing after her sister into the labyrinth within ten minutes. As she ran following Kelly’s scent, she found an old familiar smell from about ten days ago, causing her to instinctively hide herself.

Her sister was there, quietly facing off with Kelly.

"Werewolves value their promises. They are willing to spend their entire lives or even gouge out their own eyes and ears for the sake of keeping a promise. That is indeed a noble trait, but because it’s an admirable virtue without question, they wouldn’t hesitate to sacrifice everything, including their happiness."

"..."

"That child made too big a promise at such a young age. She has come this far without even knowing what love feels like, all in her determination to keep the promise of becoming your wife."

"Love... doesn't know?"

To be honest, Kate had been clinging to Kelly in a fanatical way. It felt more like faith than love.
"I want my sister to know what it's like to fall in love with someone. I'd rather she experience the process of falling for someone normally instead of dedicating herself to me until her dying day."
"...I see... If that's how it is, there's nothing else to do."
Kelly uttered a reasonable-sounding line.
While saying something so reasonable, she hadn't expected to feel like she was spitting blood inside again.
(Not this again...)
Indeed, Kate didn't think blindly following Kelly would be the best for her happiness.
But now that she might lose another woman who seemed within reach and whom she had convinced herself she could have, everything went dark before her eyes once more.
"I thought it wouldn't come to this."
Lynne nodded with a face of disgusting relief at those words wrung out like squeezing water from a sponge.

"That's probably it. She’s a bit too single-minded, and that’s what makes her cute... but..."

Kelly hadn’t been listening to Linnie. She didn’t want to hear it. She thought about retreating somewhere again and crying. Maybe she should just quit the military altogether. The feeling of giving up was overwhelming.

And because she wasn’t paying attention at all, she managed to react in time.

"!!"

The ceiling of the labyrinth trembled slightly.

The air bent ever so slightly. Pressure changed.

A monster’s presence. Not a Hell Boar, but something much stronger.

"Nooooo!!"

There was no hesitation. Because Kelly hadn’t paid any attention to her conversation with Linnie, she managed to throw her greatsword at Linnie’s back in the fastest possible moment.

Gonk!!

「Oooooooh!!」

「Huh?！」

Lynne’s ears twitched up and she spun around in alarm. A gigantic stone golem, at least twice Kelly’s size, was about to collapse behind her.

“Wha...!?”

“You were followed. You probably cut through the maze entrance near Quica a few times before making it here.”

“Y-Yes…”

“It looks like you stepped into the stone golem’s detection range.”

Kelly glanced at Lynne, who had tensed up, and quietly gathered her strength.

Kelly’s usually dark eyes glowed golden. Anger, transformed from an overwhelming sense of despair, was trying to awaken the latent power of the bull ogre that slumbered within Kelly once again.

The stone golem stirred.

She awkwardly but forcefully pulls the sword out of her chest.
“BMOOOOOO!!”
Releasing golden light from her eyes, Kelly leaps up with all the strength in her body. She kicks off the high ceiling and drives the hilt of the sword sticking into the rock figure’s chest down with all her weight.
The rock figure's breastplate splits vertically. In midair, she snatches the spinning greatsword out of the air and slashes at the rock figure’s right leg in a horizontal motion.
“!!!”
In one clean cut, it is severed at the thigh.
The rock figure loses its balance. There’s no need to wait for it to fall. Kelly spins her thick leg around, sending a whirlwind through the maze as she delivers a roundhouse kick.
“FUGOOOOO!!”
Thud!!
The rock figure topples over.

He drove his sword into the monster’s head with all his might, pinning it to the ground.

“S-Spectacular…”

“BMOOAAAH!!”

“Sir Kerry!?”

Kerry continued swinging down his fists. He kicked and smashed the broken leg of the golem, sending it flying. Each blow shattered rocks, reducing the rock figure into scattered stone blocks in a matter of seconds.

This was the special latent ability of the bull ogre.
In the labyrinth, or rather within the enclosed darkness, the bull ogre’s combat power could be dramatically increased.

The Ogre born as the Ruler of Darkness, and especially the Bull Ogre optimized to be the King of Underground, can double their offensive capabilities in such an environment.

“Still, because the Bull Ogre has gotten too used to peace, they won’t be able to pull off this kind of desperate strength unless they’re well versed in battle. I’ve been hunting with my life on the line since childhood, so it’s just natural... that’s right.”

“I see.”

“That’s why it was only natural for me to break through Rock God Labyrinth. It’s a situation where Bull Ogre excels. A trotting joust wouldn’t have worked like this.”

“…………”

“I remember now. You were there when…”

“Yes.”

Lynne had taken the Ace Knight exam with Kelly back then.

And… she was surrounded by dead bodies and stone golems, on the verge of death.

Kelly couldn’t bear to see it and saved Lynne. It was technically a violation of rules, which led to Kelly’s disqualification.

"During the time I accompanied Kate in her pursuit, I picked up a thing or two. When I heard about the Ace Knight exam being open to newcomers, I got cocky and thought it would be an honor for my hometown if I passed... but then you helped me out."

"..."

"Why did you give up on becoming an Ace Knight after that?"

"...I figured I wasn't cut out for it if helping someone else led to disqualification."

The rules are the rules, I know. But Kelly would do the same thing again in a similar situation. And so she realized... She had been pushed by others to aim for this honor but didn’t actually want it herself. Helping her comrades was enough.

"I don't need to be an Ace Knight if all I have to do is protect my friends. A crossbow’s perfect for that. Even from far away, I can help out a friend in trouble. So I decided to work hard as part of the Crossbow Corps."

"...Is that so? I thought we'd meet again next year... but I took the exam anyway and here I am now."

The leather armor on her chest bore an Ace Knight’s badge.

"And the elite Third Infantry of the West. That's quite something, isn't it?"

"I suppose I made a mistake too."

"......?"

Lynne stood before Kelly who had sat down and began to take off her armor.

Even though she was wearing long sleeves and a tunic underneath, Kelly felt a little lewd and looked away.

"If you break your promise, Kate won’t be satisfied either."

"Huh? Wait, what do you mean by that?"

"Werewolf promises are absolute. The only thing that can nullify them is another werewolf’s conflicting promise."

"I see."

"Yes. So please make a new promise with me. That way I’ll set Kate free."

“…”

She felt extremely lonely. If she said “yes” now, her honeymoon with Kate would be over.

For a fleeting moment, the thought crossed her mind that maybe if she threw a tantrum right now it might still work out, but Kelly’s spineless and calm self immediately dismissed this selfish idea.

Lynne smiled and slowly spoke as though aware of or oblivious to Kelly’s lonely struggle.

“Please make me your wife, Kelly Isaac.”

“…”

“What I’m saying is that ever since then, I’ve been looking forward to our reunion. All along, I’ve kept my feelings for you warm in the depths of my heart… This is a bond without promise, but it’s real love. Please make me your wife so that someday I can let this child experience these feelings.”

“…”

Kelly was confused by her argument and turned pale.

Then she noticed something moving at the edge of her vision and watched its movement with an ocher gaze typical of a bull.

It’s Kate. She had been hiding behind something until now.

Kate thrusts her fist upwards, signaling for Kelly to go ahead.

(…Is that okay?)

Kelly is confused by the bizarre turn of events and starts panicking when he sees Linnie looking increasingly worried.

“Am I not enough?”

“…W-well…”

“No need to worry about last night. I’ve trained myself to take your penis. If you want, I can show proof right now.”

“…………”

So that’s it, Kelly thinks as a cold sweat breaks out on his forehead. Even while she keeps such a cool face, Linnie must have been walking around with the huge dildo inside her.

Kate makes the same gesture again. Hurry up, hurry up.

「...I understand.」

「Phew, that's a relief...♪」

Lynne kissed Kelly’s large lips, burying her nose and mouth inside them, just like Kate did.

「This promise is now perfect. This way...」

「Yay!♪」

Kate suddenly jumped on Lynne from behind, surprising her.

「K-Kate?」

「Big sis, you're going to be Kelly-nii's bride too!」

「N-No, that’s not it at all! Kate, listen to me!」

「Heheh♪」

"I made a promise to marry Kelly, Kate. So your promise is no longer valid."

"Hey sis... in the Bull Ogre Colony, having multiple wives is normal."

"Eh? Eh?"

"It's different for wolf beasts. ...Sis, you can't keep both promises at once, right?"

"Eh!? Really!?"

"Oh, I see..."

It seemed that wolf beasts practiced monogamy.

And while Celesta’s society technically allowed polygamy, in human society it was basically a one-man-one-woman system.

Lynne had just moved from the wolf beast colony to a human town and hadn’t fully grasped this yet.

"Hehehe~... Sis, I’m with you! We’ll have lots of Kelly’s kids!"

“...uh, so it’s going to be like this... huh?”

“Hey, Linne... if there’s no point in doing this, let’s just forget about it.”

“Brother Kelly. Wolf Beastman, promise, absolutely. I’ve already made a promise with you.”

“Yes. Since we have made a promise, I will become your wife. ...And because of you, I’m like this now...”

Linne shyly took off her underarmour. Kate followed suit.

Linne wasn’t wearing any underwear; she couldn’t put them on.

As expected, the extremely thick phallic-shaped object was sticking out from between Linne’s legs.

“...There’s no other choice but to become your wife.”

“...Ah, yeah...”

Usually, someone would be troubled if they were blamed for their own pre-ejaculation and self-expansion, but Kelly strangely didn’t feel like complaining about it.

No, of course not.
As a male, the joy of having these overly cute wolf sisters beg him for his offspring prevented any complaints.

Kate happily and forcefully pulled out the dildo from Linnie’s crotch.

“♪”

“Aaah… Aaaah!?”

The huge fake penis was revealed with a slurping sound. On closer inspection, there was a carving of a cow’s face on it.

“…Who made this?”

“Me, big sister!”

“…Y-Yes… I couldn’t help but…”

“…How cute.”

"But starting today, I don’t need this anymore, right? Every day and every night, I’ll be able to get my dick from Kelly-nii?"

"…”

The opening of her vagina trembled in pleasure.

“…You want me to put it in?”

“Yes… umm, since I’m a virgin… could you go easy on me?”

“…I’ve only done this with Kate and it’s been less than a week since I lost my virginity.”

“No way~♪”

Amidst Kate’s seemingly happy gaze, Kelly’s cock began to push into Linne.

Because he was slightly bigger in build compared to Kate, his dick went deeper inside her. But still, it didn’t go all the way in.

Even so, Linne got drunk on the pleasure of being filled by a hot, living shaft deep within her vagina.

“Ah, aah…♪ This is Kelly’s… penis…♪”

“Dick♪”

“U-Uh… Kate, it’s embarrassing to say it like that…”

“It’s just dick?”

“But…”

“I get a little turned on when you call it dick.”

“…O-Okay, …d-dick…”

“One more time.”

“Dick. …Dick… Kelly’s bull dick…!!”

“Heh. Nice.”

「Dick... dick, it's good... more dick... use your dick on me, fuck me hard... ah, aha, indeed dick sounds so much better...♪」

Lynne had been thoroughly influenced by Kate’s direct style after being told several times.

Her cheeks flushed as she slowly moved her body up and down, swaying her tail to show how good it felt. She was well-trained from the dummy, so there was no pain, but with each moment, she was more and more absorbed in the overwhelming sensation of life force.

Lynne had been an intellectual image before, but once she started falling apart, it happened quickly. As expected, being young like Kate made her adapt fast.

「H... ha, Kelly-san, more... fuck me more... I can't take it, make me come with your dick, Kelly-san’s dick♪」

「O-oh... I’m going to cum!」

Kelly grabbed Lynne tightly in both hands. Instantly understanding what was about to happen, she looked at him with eyes full of anticipation.

「♪♪」

Juuu, juu, juu!!

With small but powerful movements, Kelly started fucking her. Because of the large difference in their body sizes, he had no choice but to move her rather than himself to control his thrusts so they wouldn’t be too deep or too fast.

And in this way, as her body was grabbed and treated like a hole meant only to take his member, Linnie tasted an unprecedented pleasure of being dominated. She felt intense bliss from being treated merely as a woman, a device for pleasure, completely negating the strong self she had as an Ace Knight.

“Ah, ha, aaaah! This is good… wau, auuuh, auuu!!”

“I’m coming… I’m coming, Linnie, I’m cumming…!? ”

“Auuu♪... Yes, wa, wat, me… Sperm in my insides… semen, put it in, fill me up, soak me… make me pregnant♪”

“U, ku, uuhh…!!”

“Aaaaaaaaahhhhhh!!”

He ejaculated deep inside Linnie.

The sisters who had different atmospheres but similar vaginas enjoyed the onslaught of Kelly’s copious amount of semen.

Shaking as her womb sucked in the white fluid, Kate licked up the overflow with a delicious sound.

“Haa…♪”

“Nn, nn, cumming... it’s such a waste...♪”

“I-I don’t need that much, ugh... Don’t do that or I’ll want to fuck you again. Who knows if anyone will be passing by here.”

“I’m gonna do it! I’m going to do it next after my sister!”

“...Man, she really is bottomless.”

◇◇◇

Lynne Mikagami. Height: 159 cm, Wolf Beastkin. Age: 19.
Passed the Ace Knight exam four years ago and was hired. Currently a squad leader in the Western Army’s Third Infantry Regiment.
Famous for her fast sword skills and body techniques, she also has an impressive fighting instinct that is hard to ignore, though lately there have been concerns about her physical condition.
Recently submitted a request to transfer to the Northern Army’s “Second Crossbow Squad.” As of now, no such unit exists on paper, and since the crossbow squad isn’t part of the official roster, it’s still under review.
There are suspicions that she may be too young for the responsibilities of a squad leader, but when asked about demotion, she readily agreed.

For the above reasons, we plan to assign them as regular soldiers once they return and are reassigned as infantry guards.

We request final confirmation from Central Command.

◇◇◇

The sixth minister frowned in headquarters.

"...Recently, isn't there a strange increase of feminine presence in Diane's unit? I thought it was supposed to be all male."

"Oh yeah, do you know about this, Minister? There’s apparently a rumor that the centurion Diane has gotten herself a boyfriend or something."

"Mm, mm. About that... It was some kind of misunderstanding or something vague and unclear, but what exactly happened?"

"There's talk of a guy. They say he’s incredibly feminine. For some reason, he seems to have quite a few demi-humans attached to him, according to the report from Special Centurion Becker."

"Mm, so it was his doing!"

"No, that’s not it."

(Continued)

A week had passed since Kelly reunited with the wolf girl, Kate.

"To think that little imp Kelly would end up hooking up with a wolf beastman of all people..."

"Don't call him an imp; at least call him a coward."

"I honestly thought he'd just discovered his sexuality with some city boy."

"From what my husband heard, a high priest granted him enlightenment."

"Wasn't there a rumor that ever since Hellbore stabbed him in the eye, it's been too painful for him to get an erection?"

The gossip among the female ogres was quite explicit.

Completely unaware of such rumors, Kelly was spending his days in happiness.

"Nngh... g-g-g..."

"Kyuu... You're sleeping soundly. Big brother Kelly, it's morning..."

Kate licked Kelly's cheek. Kelly did not wake.

Smirking at his refusal to stir, Kate gently peeled back the covers Kelly was sleeping under.

Kelly's violent, rigid member was already saying good morning.

"Ahaha."

After gazing at its heroic sight with enchantment for a moment, Kate grasped it with both hands and began licking the underside of the glans.

Kelly still hadn't woken.

"...Big brother Kelly, it's morning. Morning. It's time to do dick to me again...♪"

After whispering in a low voice—it was hard to tell if she wanted to wake him or not—she rubbed her cheek against his morning wood before slowly untying her loincloth. She wasn't wearing any underwear; she had no intention of wearing any anymore.

"It's your fault for not waking up, big brother...♪"

Then, using both hands, she pulled her labia wide to the limit, impaling herself upon Kelly's meat rod. The size difference was so extreme it looked almost painful, yet her expression was purely one of enjoyment.

"Ngo... g-g... g... ugh?"

"Ah, you're awake...?"

Just as the glans reached halfway through—the very depths of Kate—Kelly opened his eyes heavily.

What reflected in his vision was the wolf girl, half-naked, perched atop his morning erection, swaying her hips as if using his member like a piece of playground equipment, all while smiling.

"O-Oh? What's this?"

"Good morning, big brother. We're going to do lots of dick today, too♪"

"...H-Hey, now. We did it plenty of times yesterday, from morning until night."

"I'm hungry. No matter how much you eat the day before, you get hungry again in the morning, you know?"

"N-No, if you're hungry, go to Mom..."

"It's not my stomach I'm talking about. It's my vagina."

Kelly went limp.

"...You've learned some weird jokes. Who put that in your head?"

"Auntie Dorothy said it was her killer sense of humor."

Her mother's sheer boldness was giving him a headache.

Glancing toward the doorway, he saw his mother's horn peeking in. Noticing Kelly staring, she left a "thumbs-up" sign—or rather, a "thumb-pinched" sign—before retreating.

"Mom... I know you want a grandchild, but..."

"I'll make a grandkid! I'll make them diligently! Come on, big brother, let's prepare a grandkid first thing in the morning. It'll be good for your health, I'm sure."

"You..."

Kate waved both hands forward in a frantic motion. She could manage the initial entry by herself, but she couldn't handle the thrusting yet.

Her gesture was a clear plea: Hurry up, grab my body, and start pumping me up and down.

"Once I've got it inside, there's no way I can just pull it out...!"

"I'll let you out~. I'm feeling energetic today too, thanks to all that seed you gave me this morning~♪"

"I have no idea what you're even talking about..."

Kelly began to ravage Kate, just as she demanded. Kate wagged her tail with an innocent smile. Even before the sun had reached its zenith, the Isaac household was already in a state of utter debauchery.

Wake up, have sex with Kate, play with the children, have sex with Kate, occasionally go fishing or hunting, have sex with Kate, drink with comrades, have sex with Kate while tipsy, have sex with Kate while cleansing himself at the water basin before bed, and fall asleep while having sex with Kate.

"What kind of life is this?"

"Every newlywed wolf-beastman lives like this, you know?"

Kate looked at him with a puzzled expression.

"Even bull-ogres are that much of a lovey-dovey couple," Dorothy added with a solemn nod.

"That's not good for the children's education, is it?"

"I was just sitting here regretting that I didn't provide even worse education."

She was the record holder for the longest period of virginity in the bull-ogre colony—a fact that left him speechless.

"B-but... I have to return to Basson in a little over two weeks, and it's not good to get used to this."

"Just quit the military."

"You could come back, you know? I'll go to Basson. Wolf-beastman, I promise. Absolutely. I'm going to be your bride, absolutely. I don't want to be apart from you anymore, okay?"

"Ugh... even if you say that, there are no women in the barracks..."

He felt a slight gloom as he remembered the one guy who actually did bring a woman in. While not as extreme as Anzeros, Kelly was relatively of a "moralist" stripe.

Or rather, in Kelly's case, he simply found the all-male, school-like atmosphere of the barracks quite comfortable since he had almost no contact with women otherwise.

"It'll be fine, it'll be fine. It'll work itself out."

"It'll be fine, it'll be fine~♪"

"Right~♪"

With a loud clap, Dorothy and Kate performed a high-five despite their nearly sixty-centimeter height difference. It was a sight that suggested no mother-in-law drama was on the horizon, which was a relief, but the surprisingly serious Kelly clutched his head, wondering what he was going to do.

Marrying Kate was fine. He would take responsibility. He had made up his mind.

The issue was his future career; he didn't want to quit the military just yet. At the very least, he wanted to stay around until someone like Ernie became a regular soldier.

Kelly walked leisurely through the evening labyrinth, lost in thought.

In his hand, he gripped a greatsword of desert steel, crafted by dwarves. To a human, it was a massive weapon that would be difficult to even lift, but to Kelly's massive frame, it was roughly the size of a standard mid-sword.

It was a memento from his father. It was perfect for hunting Hellsbore.

Just then—

"Corporal Kelly Isaac... or rather, Decurion, is it?"

"Hm?"

A figure emerged swaying from around a corner of the labyrinth.

The atmosphere was menacing, but there was no immediate bloodlust, so while Kelly instinctively braced himself, he turned his head with a relaxed gaze.

Light armor and a cloak. A longsword hanging at the waist. A dignified woman with a piercing gaze, her tied-up hair swaying gently.

At a glance, it was clear she was not a resident of the current Desert Labyrinth. She was a soldier.

"Who are you?"

"Linne Mikagami, Decurion of the Third Infantry, Western Army."

"The Third Infantry of the West... Mikagami? As in, old man Zenga's place?"

"Yes. I am his granddaughter. It has been a long time."

The Third Infantry of the Western Army was known as an elite unit. Because they were constantly engaged in skirmishes with the Afilum Empire—the greatest threat for the time being—they were known for their extensive combat experience and particularly high ratio of Ace Knights.

And the distinctive surname Mikagami was found only among the Wolf Beastkin within this labyrinth. As expected, she was the granddaughter of Zenga Mikagami—in other words, one of Kate's sisters.

However, she lacked the exotic, unsettled air that Kate possessed. She also spoke the standard dialect with practiced ease.

"Do you happen to know my sister?"

"I do."

"I thought as much... I have been looking for you."

"I heard."

"...Is she still insisting that she will become your wife?"

"Yes."

"…………"

Rinne shook her head, looking troubled.

"That girl is prone to delusions."

"...What? Could it be..."

Suddenly, a possibility I had once considered crossed my mind.
What if?
I wondered if she had mistakenly believed in a promise that had never even been made.

Rinne smiled.

"Do not worry. A promise was made. A promise that is absolute to us."

"...I see."

"However, with the very tongue that speaks of such absolutes, I must venture to ask a favor."

"?"

"I ask that you break it."

---

While Kate was basking in the sun for a moment, Kelly had headed out to hunt.
After feeling lonely and sulking with a tight, pouting heart, Kate couldn't manage to stay upset for even ten minutes before diving into the labyrinth to chase after Kelly.
And as she ran, following Kelly's scent, she caught a nostalgic scent—one she hadn't encountered since they parted about ten days ago—and instinctively hid herself.
Her sister was there.
Her sister was facing Kelly in silence.

"The Wolf Beastkin hold promises sacred. We are a race that would spend a lifetime, or even gouge out our own eyes and ears, for the sake of a vow. It is certainly a virtue, but because it is a virtue beyond reproach, we do not hesitate to sacrifice our hearts and our happiness entirely."

"…………"

"That girl made a promise far too grand for her youth. In her desperate attempt to keep the promise of becoming your wife, she has come this far without ever knowing what it means to fall in love."

"She... doesn't know love?"

Come to think of it, Kate had been clinging to Kelly with a fervor that bordered on the fanatical. It felt less like love and more, quite literally, like religious devotion.

"I want my sister to know what it is to fall in love with someone. Rather than devoting herself until her dying breath for the sake of a promise, I want her to experience the process of simply liking someone. I want my sister to lead a rich life."

"...I see. ...Well, if that's the case, I guess there's nothing I can do."

Kelly uttered words of easy understanding.
He did not realize that, while speaking those words of understanding, he would once again taste the sensation of vomiting blood in his heart.
(...Not again.)

Certainly, he didn't believe that blindly following Kelly was the greatest happiness for Kate.
But when he realized that he was likely about to let go of the woman he thought—he was certain—was within his reach, his world went dark once more.

"I thought it was something like that."

To those squeezed-out words, Rinne nodded with a face that was almost infuriatingly relieved.

"I suppose so. She's a bit too single-minded, which is part of her charm, but..."

Kelly wasn't listening to Rinne's words. He didn't want to listen. He felt like withdrawing into some corner to cry for a while. He felt a wave of self-destructive despair, wondering if he should just quit the military altogether.

And it was precisely because he hadn't been listening to Rinne at all that he had made it in time.

"...!!"

The ceiling of the labyrinth trembled faintly.

The air buckled slightly. The atmospheric pressure shifted.

The presence of a monster. And not something as minor as a Hellsboar—something powerful.

"Nuoohhhh!!"

Without a moment's hesitation—thanks to the fact that he hadn't spared a single second of attention to his conversation with Rinne—he threw his greatsword behind Rinne at the perfect moment.

Thud!!

"Ooooooh!!"

"!? "

Rinne's ears twitched upward as she spun around in a panic. A massive rock golem, perhaps twice her size, was in the process of toppling behind her.

"Wh...!?"

"You were being followed. You probably took a shortcut through the labyrinth entrance near Quika to get here."

"Y-yes..."

"Looks like you stepped into the rock golem's detection range."

Glancing at Rinne as she braced herself, Kelly quietly began to gather strength within his body.

Kelly's eyes, usually dark, began to emit a golden radiance. Rage—a rage born from converting his directionless despair—was attempting to reawaken the latent power of the Bull Ogre slumbering within him.

The rock golem began to rise.

With awkward yet powerful movements, it attempted to pull the sword embedded in its chest.

"Bumooooooo!!"

With golden light streaming from his eyes, Kelly released the tension in his entire body and leapt in a single bound. Kicking off the high ceiling, he used his entire body weight to stomp down on the hilt of the sword stuck in the golem's chest.

The golem's chest plate split vertically. Snatching the greatsword out of the air as it spun, he swung it in a horizontal arc, cleaving through the golem's right leg.

"!!!"

It sliced through the thigh with spectacular precision.

The golem lost its balance. Kelly didn't wait for it to fall; instead, he unleashed a roundhouse kick with that thick leg, creating a gust of wind within the labyrinth.

"Fugooooo!!"

Thump!!

The rock golem stumbled and fell.

Kelly drove his sword down with brute force, pinning the creature's head to the ground.

"Th-that was incredible..."

"Bumoaaaaa!!"

"Lord Kelly!?"

Kelly followed through by bringing his fist down.

He kicked.

He grabbed the golem's broken leg and slammed it down.

Each strike literally continued to shatter the rock, and before anyone's eyes, the rock golem was dismantled into a pile of stone fragments.

The special latent ability of the Bull Ogre.
Within a labyrinth—that is, within a confined darkness—a Bull Ogre can exponentially increase its combat prowess.

Born as rulers of the darkness, Ogres possess incredible power; specifically, the Minotaur, optimized as a king of the underground, can gain attack capabilities double that of its normal state when within its natural environment.

"That said, because Minotaurs have grown too accustomed to peace, they can't tap into that kind of 'hysterical strength' unless they're well-versed in combat. I've been hunting for my life since I was a kid, so before I knew it... well, you get the idea."

"Is that so?"

"That's why it was only natural that I could break through the Rock God Labyrinth. It was the absolute perfect scenario for a Minotaur. It wouldn't have gone that way in a Trot-style duel."

"............"

"I remember now. You, back then..."

"Yes."

Linne had taken the Ace Knight exam alongside Kelly, the same one he had once challenged.
And... surrounded by Undead and Rock Golems, she had been on the verge of death.
Unable to stand by and watch, Kelly had saved her. That was technically a violation of the rules, and as a result, Kelly had been disqualified.

"While accompanying you on your pursuit of Kate, I managed to hone my skills to a certain degree. When I heard I could take the Ace Knight exam on a whim, I grew arrogant, thinking I could bring glory back to my homeland, and ended up taking it... and that was when you saved me."

"............"

"Why did you give up on becoming an Ace Knight after that?"

"...I figured if I was going to be disqualified for saving someone, then I wasn't cut out for it."

Rules are rules. He knew that.
But if a similar situation arose again, Kelly knew he would do the exact same thing. And if he did, the result would be the same.
Furthermore, Kelly had realized... that while he had pursued the title because of the pressure from those around him, he didn't truly desire the honor of being an Ace Knight. As long as he could protect his comrades, that was enough.

"I don't care about anything else, as long as I can protect my comrades. A crossbow is perfect for that. I can save allies even from a great distance. That's why I decided to give it my all in the Crossbow Corps."

"...I see. I truly thought we would meet again... I took the Ace Knight exam again the following year, and as you can see, here I am."

The insignia of an Ace Knight was embedded in the chest of her leather armor.

"And you're part of the elite Western Third Infantry. That's quite an achievement."

"Looking back, I also lost my way."

"............?"

Linne stood before the seated Kelly and began to unfasten her armor.
Since she was wearing long-sleeved, long-length under-armor, there was no issue, but Kelly felt a slight sense of impropriety and averted his eyes.

"Even if I were to break a promise, I know Kate would not accept it."

"Huh? Wait, does that mean—"

"A promise made by a Wolf Beastman is absolute. The only thing that can nullify such a promise is a contradiction with another promise made by a different Wolf Beastman. That is all."

"Is that so?"

"Yes. Therefore, please make a new promise with me. Only then can I set Kate free."

"............"

A profound loneliness washed over him. If he said "yes" to this, his honeymoon period with Kate would be over.
For a fleeting moment, the thought surfaced that perhaps he could still make it if he threw a tantrum now, but the cowardly, composed, and true Kelly within him quelled that ego.
Whether she knew of his lonely conflict or not, Linne smiled and spoke slowly.

"Please make me your wife, Kelly Isaac."

"............Huh?"

"Since that day, I have been looking forward to reuniting with you. I have kept my feelings for you warm deep within my heart. ...I believe this is a bond without a prior promise—true love. So that I may one day let that child experience these feelings as well, please make me your wife."

"............"

The logic was slightly lost on him. Kelly's mind went blank.
Then, Kelly spotted something moving in the corner of his vision, and using the characteristic strabismus of a Minotaur, he focused intently on the movement.

It was Kate. She had been hiding in the shadows until now.

Kate thrust her fist into the air. It was a sign that meant, Go for it, go for it, Big Brother Kelly!

(...Is this really okay?)

Kelly struggled to keep up with this inexplicable turn of events. And as Rinne’s eyes began to cloud with anxiety, he grew even more flustered.

"Am I... not enough for you?"

"...W-well..."

"Oh, you needn't worry about the nighttime. I have... trained myself to be able to accept even your manhood. In fact, I could show you proof right this instant."

"............"

Is that it? Kelly broke into a cold sweat. Was Rinne walking around with a massive, thick plug inserted even while maintaining such a composed expression?

Then, Kate made the same gesture again. Hurry, hurry.

"...Alright, I understand."

"Oh, thank goodness...♪"

Rinne kissed him, burying her nose and mouth within the fullness of Kelly's lips. Just as Kate had done.

"Our promise is now perfect. With this... we..."

"Yay!♪"

Suddenly, Kate lunged at Rinne from behind. It startled her.

"K-Kate?"

"Big Sister, you're a bride with Big Brother Kelly, too!"

"N-no, that's not it! Kate, listen to me!"

"Nfufu~♪"

"Since I have finalized my promise to become Kelly's wife, Kate, your promise is already—"

"Listen, Big Sister. ...In the Ox Ogre Colony, having lots of brides is normal."

"...Wh-what?"

"It's different from the Wolf Beastmen. ...You haven't created a contradiction in your promise, you know?"

"E-eh!?"

"Ah... I see. So that's how it is."

It seemed the Wolf Beastmen practiced polygamy.

And while polygamy was technically permitted in Celesta, monogamy remained the fundamental standard in human society.

Having moved directly from the Wolf Beastman Colony to a human city, Rinne hadn't fully grasped that distinction.

"Nfufu~♪ ...Big Sister, me too! Lots of Big Brother Kelly's babies!"

"...Ugh, so... that is how it's going to be..."

"H-hey, Rinne... if it's meaningless, we could just pretend it never happened..."

"Big Brother Kelly. For Wolf Beastmen, a promise is absolute. I've already made the promise."

"...That is true. Since a promise has been made, I shall become your wife. ...Besides, since I have become like this to accommodate you..."

Embarrassed, Rinne began to strip beneath her armor. Following suit, Kate began to undress as well.

Rinne was not wearing any underwear. She couldn't.

Because, as expected, a massive, thick plug was wedged deep within her crotch.

"...I have no choice but to become your wife."

"...A-ah..."

Normally, one would be troubled to have their body's preemptive self-expansion blamed on someone else, but strangely, Kelly found himself unable to complain.

No, it was only natural.
The sheer masculine joy of being begged for his child by these incredibly endearing wolf sisters left no room for such complaints.

Kate gleefully and forcefully yanked the dildo out of Linne's crotch.

"♪"

"Ah, wait... Ah, ahhh!?"

With a wet, squelching sound, the massive prosthetic phallus emerged. Upon closer inspection, a cow's face was carved into it.

"...Who made this?"

"Big sis did! ♪"

"...Y-yes... I just, couldn't help myself..."

"...It's actually kind of cute."

"But you won't need this starting today, okay? You can have Big Brother Kelly's cock every day, every night."

"Mm...! ♪"

He could clearly see her open vagina trembling with pleasure.

"...C-can I put it in?"

"Yes... U-um, I don't have any experience... so please, be gentle."

"...I've only ever done it with Kate, and I only lost my virginity a week ago myself."

"Right? ♪"

Under Kate's seemingly delighted watch, Kelly's member began to push into Linne.

Because she was slightly larger than Kate, she swallowed Kelly's shaft a bit deeper, but even so, it couldn't take the whole thing.

Even so, Linne was intoxicated by the pleasure of her deep vaginal walls being pressed upward by the raw, hot flesh of his cock.

"Ah, ahhh... ♪ T-this is... Mr. Kelly's... phallus... ♪"

"Cock! ♪"

"U-uuuh... Kate, don't say it like that, it's embarrassing."

"A cock is a cock, isn't it?"

"But..."

"I actually get a little more excited when you call it a cock."

"...I-I understand... C-cock."

"One more time."

"Cock. ...Cock... Mr. Kelly's cow-cock...!!"

"Whoa. That's the stuff."

"Cock... Cock, it feels so good... Give me more cock... Use your cock to pound me, thrust it deep inside me... Ah, ahaha, you're right, calling it a cock... the vulgar way sounds so much better... ♪"

After being made to say it several times, Linne had been thoroughly colored by Kate's blunt style.

With her cheeks flushed, she slowly, slowly moved her body up and down, wagging her tail to signal her bliss. Having trained with the dildo, there was no pain; instead, she was being progressively overwhelmed by the sensation of his overwhelming vitality with every single thrust.

Linne had an image of being the intellectual one, but once she began to unravel, it happened fast. Being young like Kate, her adaptability was remarkably quick.

"Ha... haah, Mr. Kelly, more... thrust into me even more... It's frustrating, please ruin me, ruin me with your cock, Mr. Kelly! ♪"

"O-okay... Here I go."

He gripped Linne firmly, as if enveloping her with both hands. Linne instantly realized what was coming, her eyes melting with anticipation.

"Mm...!! ♪♪"

Squish, squelch, thrust...!!

Kelly began to stroke his member within her vagina, gripping Linne's body with short, powerful movements. Because of the difference in their builds, in order to control the thrusting so it wasn't too deep or too fast to prevent slipping out, he had no choice but to move her body instead of his own.

And thus, treated as nothing more than a hole to be gripped and used to take his member, Linne experienced a level of masochistic pleasure unlike anything she had ever known. By completely denying her strong identity as an Ace Knight, she found an intense ecstasy in being treated as nothing more than a woman—a mere vessel for pleasure.

"Ah, ha, ahhh! It’s good, this is good... Wuh, auuh, auuh!!"

"Here it comes... I'm coming, Linne, I'm gonna cum...!?"

"Auh♪... Yes, I—I... the semen, inside me... put it in, fill me up, soak me... I'm gonna get pregnant♪"

"Ugh, ku, uuh...!!"

"Aaaaaaaaah!!"

He ejaculated deep inside Linne with a forceful thrust.
Despite their different temperaments, the sisters' remarkably similar vaginas both relished the same massive influx of Kelly's seed.
As her womb trembled, absorbing the cloudy fluid, Kate began to lick up the overflowing remnants with hungry, delicious intent.

"Haa...♪"

"Nn, nn, Rinne... it's a waste, don't let it go to waste...♪"

"G-Geez, don't be like that, ugh... don't do that, or it'll make me want to ravage you again, and we don't know who might walk by here."

"I'll do it! I'll do the cock next! After Big Sister, it's my turn!"

"...Good grief, you really are bottomless, aren't you?"

◇◇◇

Linne Mikagami. Height: 159 cm. Wolf Beastkin. Age: 19.
Passed the Ace Knight exam four years ago and was recruited. Currently serving as a Decurion in the Third Infantry Regiment of the Western Legion.
Renowned for her high-speed swordsmanship and martial arts, her fighting instinct in critical moments is nothing short of remarkable; however, there are recent evaluations suggesting concerns regarding her lower body strength.
A few days ago, she submitted a transfer request to the "Second Crossbow Corps" of the Northern Legion. Currently, the unit in question cannot be confirmed on paper, and as the Crossbow Corps is not on the active combat strength list, a decision is pending.
There are suspicions that she may be unable to endure the heavy responsibilities of a Decurion due to her youth; when a demotion was suggested, she accepted it without hesitation.
For the reasons stated above, upon the Crossbow Corps's reinstatement, she is scheduled to be assigned as a regular guard infantryman.
Requesting final confirmation from Central Command.

◇◇◇

At Headquarters, the Sixth Minister scowled.

"...Has it not felt as though there has been a strange increase in the number of women in Diane's unit lately? I was under the impression that the directive was to compose that unit entirely of men."

"Oh, that reminds me, Minister, did you hear? There's a rumor that Centurion Diane has a boyfriend or something."

"Mmm, mmuu... regarding that matter... I returned without a clear answer, though it was somewhat vague. What was it, exactly?"

"There is a man being talked about. The rumor is that he is a massive womanizer. Special Centurion Becker reported that, for some reason, he's managed to ensnare a great many demi-humans."

"Muu, so it is that man's doing!"

"Actually, it isn't."

(To be continued)

A week had passed since Kelly reunited with the wolf girl, Kate.

"That impotent Kelly of all people ended up getting cozy with a lycanthrope…"
"Don’t call him an impotent, at least say he’s a wimp."
"I always figured he came alive in the city, but..."
"My husband heard from some high-ranking monk that he was granted enlightenment."
"Or maybe it’s true what they say—that after getting skewered in the junk by Hell’s Boar, he can’t get it up because of the pain?"

The cow ogre woman’s gossip session was shockingly frank.

Unaware of such rumors, Kelly spent his days blissfully.
"Ngh… gogogo…"
"Mmm… you’re sleeping soundly. Kelly, it’s morning…"

Kate licked Kelly’s cheek. Kelly didn’t stir.

Kate grinned mischievously at his refusal to wake up and gently pulled back the blanket covering him.

Kelly’s throbbing erection was giving him a hearty good morning.

"Ahaha!"

After gazing at its valiant form for a moment, Kate cupped it in both hands and lapped at the underside of the glans.

Kelly still didn’t wake up.

"…Kelly, it’s morning—morning. It’s time for you to give me another dick again—♪"

She whispered in a barely audible voice, unsure if she wanted to wake him or not, then rubbed her cheek against his morning wood before slowly pulling down her loincloth. She wasn’t wearing any underwear. Never had been.

"It’s your fault for not waking up—♪"

Then, with both hands, she spread her labia as wide as she could and impaled herself on Kelly’s cock. The size difference made it almost painful, but her expression remained purely delighted.

"Nggh… gogogo… goh… ugh?"
"Ah, you’re awake…?"

Halfway inside—meaning the glans had reached the depths of Kate’s womb—Kelly slowly opened his eyes.

What he saw was the wolf girl sitting astride his morning erection, her lower half bare, smiling as she rocked her hips back and forth as if it were a toy.

"O-oh? What is it?"
"Morning, Kelly. We’re gonna get you hard again today—♪"
"…Whoa, whoa. Didn’t we do this from morning till night yesterday?"
"I’m hungry—no matter how much I ate the day before, I always get hungry in the morning, right?"
"N-no, if you’re hungry, go ask Mom."
"It’s not my stomach—it’s my womb!"

Kelly deflated.

"…Did someone teach you that weird joke? Who put that in your head?"
"Dorothy Aunty’s signature humor," she said with a grin.

The sheer boldness of his mother made Kelly’s head ache.

He glanced toward the doorway and saw his mother’s horns peeking out. Realizing she was being stared at, she gave him a thumbs-up—well, more like a thumb-squeezed sign—and disappeared back inside.

"Mom… just because you want a grandkid so bad…"

"I'm gonna make you one! I'll work hard to make you one! Here, here, big brother's gonna get you started on grandkids first thing in the morning. It's gotta be good for your health!"

"You're something else, you know that?"

Kate flapped her hands in front of her like she was demonstrating. She could manage getting it in herself, but she still couldn't do the piston motion.

So she was gesturing for him to grab her and start pumping up and down, thump-thump, thump-thump.

"I can't exactly just leave it in there after I've got it in, you know...!"

"I'll pull out! I'm all fired up with your seed this morning too, meow~"

"What are you even saying..."

Kerry started fucking Kate as she was asked. Kate wagged her tail with an innocent smile. The Isaac household had been thoroughly debauched before the sun even reached its zenith.

Waking up, fucking Kate, playing with the kids, fucking Kate, occasionally going fishing or hunting, fucking Kate, getting drunk with the guys, fucking Kate while tipsy, fucking Kate while washing himself at the water source before bed, and falling asleep fucking Kate at night.

"What kind of life is this?"

"All wolfkin newlyweds are like that, you know?"

Kate looked puzzled.

"Even cow ogre couples are all over each other like that."

Dorothy nodded solemnly.

"That's not good for raising kids."

"I was just regretting not giving them worse education," said the record holder for longest-lasting virgin in the cow ogre colony.

"But, but… I have to go back to Bassoon in a little over two weeks, and I don't want to get used to this."

"Just quit the army."

"You could come with me? I'll go to Bassoon! Wolfkin, promise. Definitely. You'll be my husband, definitely. I don't wanna be apart anymore?"

"Hmm… even if you say that, there aren't any women in the barracks…"

He remembered one guy who had brought a woman along and felt a little gloomy. Not as much as Anzeros, but Kerry was also quite a stickler for discipline.

Or rather, in Kerry's case, he just felt a certain comfort in the all-male atmosphere of the barracks where there were hardly any women around.

"It'll be alright, it'll be alright, we'll figure something out."

"It'll be alright, it'll be alright, meow~"

"Meow~!"

Ding! Dorothy and Kate gave each other a high-five with a height difference of nearly 60 centimeters. It was a slightly reassuring sight since there didn't seem to be any potential for a mother-in-law problem, but the surprisingly earnest Kerry was now wondering what he was going to do.

Getting married to Kate was fine. He'd take responsibility. He was already resigned to it.

The only thing left was whether or not to resign from the army, but he still didn't want to quit just yet. At least until he could see Arnie become a regular soldier.

Kerry walked slowly through the evening labyrinth, lost in thought.

In his hand was a dwarven-made greatsword of desert steel. For a human, it would be an impossible weapon to lift, but for Kerry's massive frame, it was about the size of a normal mid-length sword.

It was something he'd inherited from his father. Perfect for hunting hellbeasts.

And then…

"Private First Class Kelly Isaac… or rather, Sergeant, isn't it?"

"Huh?"

A figure flickered into view from the corner of the labyrinth.

The aura was dangerous, but there wasn’t any immediate murderous intent—though Kellie instinctively braced herself emotionally while still leisurely turning her head to take in the newcomer.

Light armor and a cloak. A longsword slung at her hip. Her neatly tied hair swayed gently as she met Kellie’s gaze with a dignified look.

At first glance, it was clear she wasn’t one of the current desert labyrinth’s residents. A soldier.

"Who are you?"

"I am Linne Mikagami, squad leader of the Third Infantry from the Western Army."

"The Third Infantry of the West… Mikagami? That’s Zenga-uncle’s…"

"Yes. His granddaughter. It’s been a while."

The Third Infantry of the Western Army was known for its elite status. Constant skirmishes with the Afilm Empire, their greatest immediate threat, had given them extensive combat experience—particularly a high ratio of ace knights.

And the distinctive surname "Mikagami" was only found among the Lupine race in this labyrinth. As expected, she was Zenga Mikagami’s granddaughter—the sister of Kaito’s sibling.

But unlike Kaito, there was no exotic, unstable air about her. She handled standard speech with ease.

"Do you know anything about my sister?"

"I do."

"I thought so… She’s been looking for you."

"I’ve heard."

"…Still insisting she’ll marry you, I see."

"Yeah."

"…………"

Linne shook her head as if troubled.

"That girl has a very strong imagination."

"...What? Could it be…"

A possibility she’d once considered flashed through Kaito’s mind.

Maybe…

Perhaps she’d misunderstood some unmade promise and believed it to be true.

Linne smiled.

"Don’t worry. A promise was made. One that is absolute for us."

"...I see."

"But with this tongue that speaks of absolutes, I must humbly ask…"

"?

"That you break it."

While Kaito was basking in the sun, Kellie had gone out hunting.

Lonely and sulky, Kaito pouted for only a few minutes before chasing after Kellie into the labyrinth.

And as she followed Kellie’s scent, she found a familiar one—no, one from just ten days ago—and reflexively hid herself.

Her sister was there.

My sister stood silently facing Kelly.

"Werewolves value their promises above all else. They are a race that would gladly spend their entire lives, or even gouge out their own eyes and ears, to uphold a vow. It is certainly a virtue, but precisely because it is an unassailable one, they will sacrifice everything—heart, happiness, even life itself—without question."

"……"

"That child made a promise far too great for her young age. In trying to keep her word to become your wife, she’s come this far without ever knowing what love is."

"Love… she doesn’t know it?"

Now that he mentioned it, Kate had been clinging to Kelly with something bordering on fanaticism. It felt less like love and more like outright worship.

"I want my sister to experience falling in love with someone. I want her to know the normal process of liking someone, rather than dedicating herself to a promise until the very end. I want her to live a rich life."

"…I see. …Guess there’s no helping it then."

Kelly delivered a surprisingly reasonable line.

He had no idea that delivering such a reasonable line would make him feel like he was vomiting blood in his mind once again.

(…Again?)

Certainly, he didn’t think blindly following Kelly was truly what Kate wanted most.

But the thought of letting go of a woman he’d believed—no, assumed—was within reach made his vision go black for real this time.

"I figured it wasn’t that simple."

Lynne nodded with an almost irritatingly relieved expression at the strained words.

"Right? That girl’s a bit too single-minded; it’s kind of endearing, though…"

Kelly hadn’t heard Lynne’s words. He didn’t want to hear them. He wanted to hole up somewhere and cry for a while. Maybe even quit being a soldier, he thought despairingly.

And because he didn’t listen to Lynne, he reacted in time.

"…!!"

The ceiling of the labyrinth trembled faintly.

The air subtly warped. The pressure shifted.

A monster’s presence. Not just any monster—something powerful.

"Nyuooooo!!"

No hesitation. Thanks to not being distracted by his conversation with Lynne for even a moment, he threw his greatsword behind her at the perfect instant.

Gonk!

"OOOOOOOOOO!"

"!?"

Lynne’s ears perked up, and she spun around in a panic. A giant rock golem, twice Kelly’s size, was collapsing behind her.

"What…!?!"

"You’ve been followed. Probably took a shortcut through the labyrinth near Quuika to get here."

"Y-yes…"

"Looks like you stepped into the rock golem’s awareness range."

Kelly watched Lynne tense up, quietly gathering power within himself.

His normally dark eyes now shone with golden light. The fury—anger born from unplaceable despair—was awakening the dormant strength of the bull ogre slumbering within him.

The rock golem rose.

He awkwardly but powerfully tried to pull the sword embedded in his chest.

"BOMOOOOOOOOOOO!!"

With golden light radiating from his eyes, Kelly released all the tension in his springs and leaped into the air. He kicked off the high ceiling, slamming his full weight onto the hilt of the sword stuck in the rock golem’s chest.

The rock golem’s breastplate split vertically. He snatched the massive blade out of the air as if yanking it away, then sliced through the golem’s right leg in one clean stroke.

"!!!"

Perfectly bisected at the thigh.

The rock golem lost its balance. No need to wait for it to fall. Kelly swung his thick leg, kicking up a gale within the labyrinth as he delivered a spinning heel kick.

"FUGOOOOOOOOO!!"

ZUN!

The rock golem stumbled and collapsed.

He then forcefully drove the sword into its head, pinning it to the ground.

"O-oh, impressive…"

"BOMOOAAAAAA!!"

"Kelly-dono!?"

Kelly brought his fist down without hesitation.

He kicked.

He grabbed the golem’s broken leg and slammed it down.

Each blow literally shattered rock, and in an instant, the rock golem disintegrated into a pile of rubble.

The cow ogre’s special latent ability.

In the labyrinth—the enclosed darkness—it could exponentially increase its combat power.

Born as the ruler of darkness, the ogre, and among them, the cow ogre optimized as the king of the underground, could gain double its normal attack power in that environment.

"Still, even cow ogres have gotten too used to peace, so they can’t unleash this kind of desperate strength unless they’re really battle-hardened. I’ve been hunting on the edge of death since I was a kid, so it just… happens."

"Is that so?"

"That’s why it was only natural for me to break through the Rock God Labyrinth. It’s the cow ogre’s absolute specialty. A Troto-style trial by combat wouldn’t have worked."

"…………"

"I remember now. You… back then…"

"Yes."

Lynne had taken the Ace Knight exam alongside Kelly when he first attempted it.

And… she was surrounded by corpses and rock golems, moments from death.

Kelly couldn’t stand it and saved her. It was a rule violation, and Kelly was disqualified for it.

"Chasing after Kaito, I picked up some skills myself. When I heard you could take the Ace Knight exam as a wild card, I got arrogant, thinking I could bring glory to my hometown, so I took the test… and that’s when you saved me."

"…………"

"Why did you give up on becoming an Ace Knight after that?"

"…If helping people gets you disqualified, then I guess I’m not cut out for it."

Rules are rules. He understood that.

But if the same thing happens again, Kelly will probably do the same thing. And then it'll be the same old story.

And then Kelly realized… he’d been goaded into aiming for Ace Knight by everyone around him, but deep down, he didn’t actually want the title. He just wanted to help his comrades.

"I don't care about being an Ace Knight. A crossbow is perfect for what I need. I can save allies no matter how far away they are. That's why I decided to stick with the crossbow unit."

"...I see. I thought… that we would meet again… so I took the test for Ace Knight next year, and now look at me."

The Ace Knight insignia was embedded in her leather armor.

"And here she is, a member of the elite Third Infantry of the West. Quite impressive."

"Looking back, I made a mistake too."

"............?"

Lynne stood in front of Kelly as he sat down and began to remove his armor.

Even though she wore long-sleeved, full-length underarmor, Kelly felt a little aroused and looked away.

"Breaking your promise won't sit well with Kate."

"Huh? Wait, what—"

"A werewolf's promise is absolute. The only way to invalidate it is through another werewolf's conflicting promise."

"Is that so?"

"Yes. So please make a new promise with me. That way, you can free Kate."

"............"

He felt terribly lonely. If he said "yes" now, his blissful time with Kate would be over.

For a fleeting moment, the thought crossed his mind that maybe if he threw a tantrum right now, he could still salvage things—but the real Kelly, the spineless, level-headed one, calmed himself down.

Knowing or not knowing about Kelly’s lonely inner conflict, Lynne smiled and spoke slowly.

"Make me your wife, Kelly Isaac."

"............Huh?"

"I've been waiting for our reunion since that day. I've kept my feelings for you warm in the depths of my heart ever since… This is a bond without promises, true love, I believe. Please make me your wife so that one day I can share this feeling with her."

"............"

The point was slightly unclear. Kelly went pale.

Then, he noticed something moving in the corner of his vision and watched it intently with his wolf-ogre’s characteristic cross-eyed gaze.

It was Kate. She’d been hiding in the shadows until now.

Kate raised her fist. It was a signal: Go, go, Kelly!

(…Is this okay?)

Confused by the bizarre turn of events, Kelly hesitated. Then, as Lynne’s eyes began to look increasingly anxious, he panicked even more.

"Am I not enough?"

"...W-well—"

"Oh, don’t worry about the night. I’ve trained myself to… accept your manhood too. If you like, I can show you proof right now."

"............"

Could it be? Kelly broke out in a cold sweat. Was Lynne walking around with a massive prosthetic inside her while maintaining such a cool demeanor?

And then Kate made the same gesture again. Hurry, hurry.

"…I understand."

"Good…" ♪

Lynne pressed her nose and mouth deep into Kelly’s large lips, kissing him as she had with Kate.

"This promise is perfect now. With this…"

"Yay!"

Kate suddenly burst from behind, tackling Lynne. She was surprised.

"K-Kate?"

"Sis is gonna be Mrs. Kelly too!"

"T-That’s not true! Listen to me, Kate!"

"Nfuu—"

"I made a promise with Kelly, so your promise is…"

"Well, sis… in the Cow Ogre Colony, having lots of wives is normal."

"…Eh? Eh?"

"It’s different from werewolves… Your promise doesn’t make sense, sis. It can’t work like that?"

"E-Excuse me!?"

"Ah, I see. That’s how it is."

Apparently, werewolves practiced monogamy. And while Celesta technically allowed polygamy, human society still upheld monogamy as the standard. Lynne, having moved directly from a werewolf colony to a human city, hadn’t fully grasped that yet.

"Nfuu… Sis, let’s go together! Lots of Kelly’s kids!"

"…Ugh, so… it will come to this…"

"H-hey, Lynne… if there’s no point, we can just pretend it never happened."

"Kelly, werewolf promise, absolutely. I already made a promise."

"…Yes. Because I promised, I will be your wife. …Besides, I’ve become like this because of you…"

Lynne shyly began to remove her underarmor. Kate did the same.

Lynne wasn’t wearing any underwear. She couldn’t.

As expected, a thick, imposing prosthetic was lodged in Lynne’s crotch.

"…There’s no choice but for me to become your wife."

"…Y-yeah…"

Normally, he’d be annoyed at being blamed for her self-inflicted expansion with precum, but Kelly found himself unable to complain. No, it was only natural. The joy of a male, having his own children demanded by these two so endearingly wolfish sisters, prevented any complaints.

Kate gleefully yanked the prosthetic out of Lynne’s crotch with force.

"♪"

"Agh… ah, aah!?"

With a juurli, the massive phallic imitation emerged. A closer look revealed it was carved with a bull’s face.

“…Who made this?”

“Sis~”

“…Y-yes… I just…”

“…Isn’t it cute?”

“But from today, you don’t need this anymore? You can get your dick pumped by Kelly-don every day, every night?”

“Ugh…♪”

The opened vagina visibly trembled in pleasure.

“…I-I can put it in?”

“Yes… w-well, I’ve never done this before… so, if you could be gentle?”

“…I’ve only ever been with Kate too, and I just lost my virginity a week ago.”

“R-right~?”

Under Kate’s gleeful watch, Kelly’s member was thrust into Lynn’s depths.

Being slightly larger than Kate, she took in Kelly’s cock deeper than before, but still couldn’t fully accommodate it.

Even so, Lynn was intoxicated by the pleasure of being filled deep within her vagina by a raw, hot flesh.

“A-ah…♪ This is… Kelly-san’s… dick…♪”

“Dick~”

“U-ugh… Kate, that’s embarrassing.”

“Dick is dick, isn’t it?”

“But…”

“I get a little more excited when you call it ‘dick’ too.”

“…O-okay… d-dick.”

“Again.”

“Dick. …Dick… Kelly-san’s bull dick…!!”

“Uho. Nice.”

“Dick… dick, so good… more dick… fill me with your dick… ah, aha, yeah, the crude way of saying it is definitely sexier…♪”

After being made to say it several times, Lynn was fully dyed in Kate’s direct style.

Her cheeks flushed red as she slowly, slowly moved her body up and down, wagging her tail to show how good it felt. Training with the prosthetic had left her without pain, but the overwhelming sense of raw vitality consumed her more and more with each passing moment.

Lynn had always seemed intellectual, but once she started unraveling, it happened fast. Like Kate, she adapted quickly because they were both young.

“H… haah, Kelly-san, more… more, fill me up… I’m so frustrated, ruin me, ruin me with your dick♪”

“O-okay… here I come.”

He gripped Lynn tightly, as if embracing her with both hands. Lynn instantly understood what was coming and her eyes glazed over in anticipation.

“Ughhh!!”

Ju, ju, jut…!!

Kelly seized Lynn’s body in short, forceful thrusts, stroking his cock inside her. Because of the size difference, he had to move quickly, controlling himself so as not to pull out too deeply. It was Kelly who had to adjust, not the woman.

And so, treated as nothing more than a hole to hold his body and devour his cock, Lynn tasted an unprecedented pleasure in her submission. She denied the strong Ace Knight she once was, finding intense ecstasy in being treated as nothing but a woman, a pleasure device.

"A-ah, haaah! Good, this is good… wau, auuu, auuu!!"

"I'm coming… I'm coming, Lynn, I'm gonna cum…!?"

"Auu♪… yes, I, I… sperm, inside me… semen, fill me, soak me, drown me… I'm pregnant♪"

"Ugh, ugh, uuuu…!!"

"Aaaaaaaaaah!!"

He slammed his seed deep inside her.

The vaginas of the sisters, so different in demeanor yet so alike in form, both relished the deluge of Kelly’s hot jism.

Trembling, her womb sucked in the milky white fluid, and the overflow that gushed out was lapped up by Kate with greedy delight.

"Haa…♪"

"Mm, mm, rel… such a waste…♪"

"W-wait, ugh… don’t do it so much, or I’ll want to fuck you again. Who knows who’s going through here?"

"I’m next! After big sis, it’s my turn!"

"...Seriously, the bottomless pit."

◇◇◇

Lynn Mikagami. Height: 159cm. Werewolf. Age: 19.

Passed the Ace Knight exam four years ago and was recruited. Currently serves as a Tōninchō (leader of ten) in the Third Infantry Regiment of the Western Army Corps.

Renowned for her swift swordsmanship and acrobatics, she possesses an awe-inspiring survival instinct in battle—but recent evaluations note concerns about her legs.

She submitted a transfer request to the Northern Army Corps’ "Second Crossbow Corps" several days ago. However, that unit cannot be confirmed on record, as the Crossbow Corps is not listed as an active force—judgment pending.

There’s also suspicion that she couldn’t handle the weight of being a Tōninchō due to her youth, and when demotion was suggested, she readily accepted.

Therefore, upon the Crossbow Corps’s reactivation, she will be reassigned as a regular guard infantry soldier.

Awaiting final confirmation from Central Command.

◇◇◇

The Sixth Minister wore a grim expression in the command center.

"...Lately, hasn’t Diāne’s unit been getting strangely… more female? I thought the guideline was to staff it with men only."

"Oh, you know about that, Minister? Apparently, Diāne’s Tōninchō got a boyfriend or something."

"Mm, mmm… that matter… well, it came back as a misunderstanding, or rather, vaguely unresolved. What was it again?"

"There’s a guy rumored to be involved. Supposedly a real womanizer. Somehow manages to hook up with tons of demi-humans, according to reports from Special Tōninchō Becker."

"Mmm, that must be his doing!"

No, it isn’t.

(To be continued)

A week had passed since Kelly reunited with the wolf-girl Kate.

"That imp of a Kelly, what's next? He's actually pairing up with a werewolf beast-person..."

"Don't call him an imp; at least say he's a wimp."

"I always thought that guy finally woke up to men in the city."

"According to my husband, some respected monk supposedly granted him enlightenment."

"There was even talk that since getting skewered by Hell's Boar, he's been too sore to get an erection."

The gossip among the cow-ogre women is rather candid.

Unaware of any such rumors, Kelly was living a happy life.

"Mmm... g-guh..."

"Kyuu... You're sleeping well, Brother Kelly. It's morning already..."

Kate licked Kelly's cheeks repeatedly while he remained unresponsive. Amused by his refusal to wake up, she gently pulled back the cloth covering him.

Kelly's violent masculinity was currently in full "good morning" mode.

"Aha!"

After gazing admiringly at his bold display for a moment, she grabbed it with both hands and began licking the underside of the glans.

Kelly still hadn't stirred.

"...Brother Kelly, it's morning already—morning! It's time for me to get my fill again...♪"

After whispering these words in a voice too soft to determine whether she wanted to wake him or not, she nuzzled against his erection, then slowly removed her loincloth. She wasn't wearing underwear; she had no intention of putting any on.

"You're the bad one for not waking up...♪"

Then, using both hands to spread her labia as wide as possible, she allowed herself to be skewered by Kelly's penis. The size difference was so extreme it looked almost painful, yet her expression remained purely joyful.

"Mmph... g-guh... guh... uh?"

"A... you're awake...?"

As the glans reached halfway down—deep into Kate's depths—he opened his heavy-lidded eyes.

What he saw was a wolf-girl sitting atop his own morning erection, having removed only her lower garments, smiling as she swayed her hips back and forth like a playground toy.

"Oh... oh? What is this?"

"Good morning, brother! I'm going to give you plenty of cunnilingus today too...♪"

"...Oh, come on. Didn't we do this multiple times from morning till night yesterday?"

"My stomach's hungry. No matter how much I eat the day before, my stomach gets hungry again in the morning?"

"N-no, if you're hungry, ask your mother."

"Not my stomach! My vagina!"

Kelly slumped in defeat.

"...You've got a weird sense of humor. Who taught you that kind of thing?"

"Dorothy auntie's signature move: killer humor."

His head throbbed at his mother's boundless boldness.

Glancing briefly toward the doorway, he noticed his mother's horns peeking out. Realizing she was staring intently at him, she left behind a thumbs-up gesture—more like a thumb-between-fingers sign—and retreated inside.

"Mom... just because you want grandchildren..."

"I'll make them! I'll make lots of them! Come on, big brother, let's prepare for grandkids first thing in the morning. It'll be great for your health!"

"You're something else..."

Kate flapped her hands forward with a pat-pat rhythm. She could handle inserting herself alone, but she still couldn't manage the piston-like motion.

So this was her gesture: grab my crotch quickly and thrust up and down with a zup-zup.

"If you stick your cock in there, you can't just pull out again, right...!"

"I will! Today too, I'll be full of fresh seed from morning on, so I'll feel great too~♪"

"What the hell are you talking about..."

Kerry began to make love to Kate as she demanded it. While Kate wagged her tail with an innocent smile, the Isaac household was already thoroughly ruined before midday sun even touched the sky.

Wake up in the morning, have sex with Kate, play with the kids, have sex with Kate again, go fishing or hunting occasionally, have sex with Kate once more, drink with comrades until slightly drunk, then have sex with Kate while washing off at the water source before bed, and finally fall asleep having sex with Kate all night long.

"What kind of life is this for me?"

"Isn't that normal for wolf-beastfolk newlyweds?"

Kate asked with a puzzled expression.

"Even cow-ogres have those hot-and-heavy couples around," Dorothy nodded solemnly.

"That's not good for the kids' upbringing, is it?"

"I actually regretted not giving them even worse education myself."

A cow-ogre virgin colony record holder who couldn't even make a gugu sound.

"But still... I have to return to Basson in about two weeks, and getting used to this isn't good."

"Just quit the army already!"

"Can't I stay? I'll go to Basson! Wolf-beastfolk, promise me—absolutely. I'll become your wife, absolutely. Let's never be separated again, okay?"

"Hmm... but even if you say that, there are no women in the barracks..."

He remembered someone being dragged in recently and felt a bit gloomy. While not as extreme as Anzeros, Kerry was also somewhat of a moralist.

Or rather, for Kerry's case, it was just that he felt more comfortable with the school-like atmosphere of the barracks where there were almost no female contacts.

"It'll be fine, don't worry, something will work out."

"It'll be fine, it'll be fine, it'll be okay~♪"

"Heh~♪"

Pachi! Dorothy and Kate gave each other a high-five despite their nearly 60-centimeter height difference. It was reassuring that no mother-in-law problems seemed likely, but Kerry, surprisingly serious, began to worry about what would happen next.

Marrying Kate was fine; he'd take responsibility. He'd already made up his mind.
The real issue was whether to stay or go. Still, he didn't want to quit the army yet. At least he wanted to keep an eye on things until someone like Earnie became a regular soldier.

Kerry wandered leisurely through the evening maze while lost in thought.
In his hand was a dwarven-made greatsword of desert steel. To humans, it would be a massive weapon barely liftable, but for Kerry's giant frame, it was just an ordinary mid-sized sword.
It had been his father's heirloom—perfect for hunting Hell Boars.
And that was all.

"Kelly Isaac, Sergeant... no, Squad Leader, correct?"

"Hm?"

A shadowy figure flickered into view from a corner of the labyrinth.

The atmosphere was tense, yet there was no immediate sense of murderous intent. Kelly nonetheless braced herself instinctively, though outwardly she kept her demeanor casual as she surveyed the woman.

She wore light armor and a cloak, with a longsword slung at her hip. Her hair flowed loosely, and her gaze was sharp and commanding.

At first glance, it was clear she wasn't one of the current inhabitants of this desert labyrinth. She was a soldier.

"Who are you?"

"I am Linne Mikagami, captain of the Third Infantry Regiment of the Western Legion."

"The Third Infantry from the West... Mikagami? That's Zenga's family name."

"Yes. I am his granddaughter. It has been some time."

The Third Infantry Regiment of the Western Legion is renowned as an elite unit. Frequently engaged in skirmishes with their greatest current threat, the Afilum Empire, its members boast extensive combat experience and a notably high proportion of Ace Knights.

Moreover, the distinctive surname Mikagami appears only among the wolf-beastkin in this labyrinth. As expected, Linne was Zenga Mikagami's granddaughter—making her one of Kate's sisters.

Yet, unlike Kate, Linne lacked that foreign, uneasy aura. She spoke with standard fluency.

"Do you have any idea where my sister might be?"

"I do."

"As I thought... I've been looking for you."

"Heard."

"...So you're still insisting on becoming my wife?"

"Yes."

"..."

Linne shook her head, looking troubled.

"That girl is very set in her ways."

"...What? Could it be..."

A possibility that had once crossed her mind suddenly surfaced again.

Perhaps...

She hadn't actually made the promise; she might have simply misunderstood and believed it out of confusion.

Linne smiled.

"Don't worry. The promise was made. It is something absolute to us."

"...I see."

"But, with this tongue that speaks so confidently of absolutes, I would like to make one request."

"?"

"I ask that you break it."

Sister faced Kelly quietly.

"The Werebeasts honor their vows above all else. We are a race willing to dedicate our entire lives, even gouging out our own eyes and ears, to fulfill a promise. It is certainly a virtue—a flawless one—but precisely because it is so unassailable, we do not hesitate to sacrifice our hearts, our happiness, and everything else in its name."

"…………"

"She made a promise far too grand for her young age. In her desperate desire to uphold the vow of becoming your wife, she has come this far without ever knowing what love truly is."

"Love… she doesn't know?"

As you say it, Kate had clung to Kelly with an almost fanatical intensity. It felt less like affection and more like a literal faith.

"I want my sister to understand what it means to fall in love with someone. Rather than devoting herself entirely to this vow until her dying day, I wish she could experience the ordinary process of falling for someone. I want her to live a rich and fulfilling life."

"…I see. …Well, there's no way around that then."

Kelly delivered those words with remarkable understanding.

Yet he never imagined that while speaking such reasonable lines, his heart would once again feel as though it were bleeding out.

(…Again?!)

He certainly didn't believe that blindly trusting Kelly was Kate's greatest happiness.

But the thought of losing the woman he had believed was within reach—the one he had convinced himself belonged to him—made his vision darken once more, this time with finality.

"That wasn't what I was thinking at all," Linne muttered, nodding with a look of infuriating relief.

"Of course. She's just so single-minded… and there's something endearing about that…"

Kelly hadn't been listening to Linne. He didn't want to listen. Another round of hiding away in some corner, weeping uncontrollably. Perhaps he should quit the military too; he felt utterly defeated.

And precisely because he had ignored Linne's words completely, he was now ready.

"…!!!"

The ceiling of the dungeon trembled faintly.

The air warped slightly. The pressure shifted.

A presence of a monster approached—not merely a Hellboar, but something far more powerful.

"Grrrroooaaahh!!!"

No hesitation for even a heartbeat. Thanks to having given his full attention to the conversation with Linne, he seized the fastest possible moment and hurled his greatsword behind her.

Clang!

"AAAAAAAGH!!!"

"!?!"

Linne's ears shot up as she spun around in panic. Behind her stood a colossal stone golem, twice the size of Kelly, teetering on the brink of collapse.

"Nn…?!"

"You've been tailed. Most likely, you took repeated shortcuts near the Queenica dungeon entrance to get here."

"Y-yes…"

"It seems you stepped into the golem's perception range."

While keeping an eye on Linne bracing herself, Kelly quietly gathered his strength.

His usual dark eyes now glowed with golden light. The fury born of unexpressed despair awakened the dormant power of the Bull-Ogre sleeping within him—a force he hadn't felt in years.

The stone golem rose to its feet.

He attempts to draw the sword embedded in his chest with an awkward yet powerful motion.
"Brumoooooooh!!"
Golden light erupts from his eyes as Kelly releases all his coiled strength, leaping into the air in a single bound. He kicks off the high ceiling and brings his full body weight down on the hilt of the sword protruding from the golem's chest.

The golem's chest plate splits vertically. Catching the greatsword mid-air like a spinning top, he swings it horizontally to cleave through the golem's right leg in one strike.
"!!!"
Just as expected—split cleanly down the middle of its thigh.

The golem loses its balance. There's no need to wait for it to fall; Kelly delivers a spinning kick with that thick leg, stirring up dust throughout the dungeon.
"Fugoooooooh!!"
Thud!!
The golem stumbles and collapses.

He drives the sword straight down into its head, pinning it firmly to the ground.

"Oh, how magnificent..."

"Brumoooaaah!!"

"Lord Kelly!?"

Without hesitation, Kelly brings his fist crashing down.
He kicks.
He grabs the broken leg of the golem and smashes it downward.
Each blow shatters the rock further; in moments, the golem is reduced to a pile of scattered stones.

The special latent ability of the Bull Ogre:
Within the dungeon—that sealed darkness—the Bull Ogre can dramatically enhance its combat power.

Born as the master of darkness, among ogres it has been optimized specifically for life underground. In such environments, it gains an attack capability twice that of its normal state.

"Though even so, because the Bull Ogres have grown too accustomed to peace, they've lost the capacity to unleash this kind of battle fury unless they're truly seasoned in combat. I've been hunting with my life on the line since childhood, so somehow... I ended up like this."

"That's right?"

"That's why breaking through the Rock God Dungeon was no surprise for me. It's their absolute specialty. A Trot-style arena match wouldn't have worked back then."

"..."

"I remembered. You... at that time..."

"Yes."

Linne had taken the Ace Knight Trial alongside Kelly, whom he once challenged.
And there... surrounded by a Dead Corpse and a Rock Golem, she was moments from death.
Seeing her in such peril, Kelly saved her—a move that violated the rules and resulted in his disqualification.

"Since Kate started following you, I've gained some skill myself. When I heard about the Ace Knight Trial being open to outsiders, I arrogantly thought it would bring glory to my hometown, so I signed up... and at that time, you saved me."

"..."

"So why did you give up on becoming an Ace Knight?"

"...If saving people leads to disqualification, then I don't think I'm suited for this path."

Rules are rules. He understands that well enough.

But if a similar situation arises again, Kelly will do the same thing. And that's exactly what it is.

Then Kelly realized... he had been driven by the crowd to aim for this, but in truth, he didn't desire the honor of Ace Knight. All he wanted was to protect his comrades.

"Look, I just need to guard my friends. Isn't a crossbow perfect for that? I can reach and aid comrades even from great distances. So I've decided to work hard with the Crossbow Squad."

"...Really? I thought we might meet again... That's why I applied for Ace Knight again this year, and now I'm in this position."

Embedded on the chest of her leather armor was the insignia of Ace Knight.

"And there stands the elite Third Infantry Regiment from the West. Quite impressive, isn't it?"

"Reflecting on it, I too have strayed from the right path."

"...?"

Linne stood before the seated Kelly and began to remove her armor.

Though she wore long sleeves and a full-length undersuit beneath, making such exposure unnecessary, Kelly felt a bit awkward and looked away.

"If we break our promise, Kate won't accept it."

"Huh? What do you mean by that?"

"A wolf-beastman's vow is absolute. The only way to invalidate such a vow is through another conflicting vow from a different wolf-beastman—that's the only possibility."

"Is that so?"

"Yes. So, please make a new promise with me. That will free Kate."

"......"

His heart sank. If he simply nodded now, his idyllic time with Kate would end.

For a fleeting moment, he considered throwing a tantrum and changing things at the last minute, but true Kelly—cowardly yet calm and rational—silently quelled that selfish impulse.

Unaware of Kelly's sorrowful inner turmoil, Linne smiled gently and slowly wove her words.

"Make me your wife, Kelly Isaac."

"...Huh?"

"Since that day, I've been waiting for our reunion. I've kept my feelings for you warm deep within my heart... This bond without a formal promise, this true love—I want to let that child experience such feelings someday too. So please, make me your wife."

"......"

The point of her argument was unclear, leaving Kelly completely baffled.
Then, he noticed something moving in the corner of his vision and tracked it with the peripheral awareness unique to a bull ogre.
It was Kate. She had been hiding in the shadows until now.
Kate raised her fist—a signal: Go on, go ahead, big brother Kelly.

(...Is this okay?)

Confused by the bizarre turn of events, Kelly struggled to keep up. As Linne's eyes grew increasingly anxious, his panic intensified.

"Am I... not enough?"

"...W-well..."

"Oh, don't worry about tonight. I've trained myself to accept even your manhood. If you'd like, I can prove it right now."

"......"

Kelly broke out in a cold sweat. Was Linne really walking around with such an intense erection while maintaining her cool composure?
Then Kate made the same gesture again: Hurry up, hurry up.

"…I understand."

"That's good… ♪"

Linne presses her nose and mouth into Kelly's large lips, kissing him just as she did with Kate.

"This promise is now perfect. With this…"

"Woo-hoo! ♪"

Kate suddenly leaps onto Linne from behind, startling her.

"K-Kate?"

"Sister, Brother Kelly, and… the bride!"

"N-No, that's wrong! Kate, listen to me!"

"Nfu-fu-♪"

"I made the promise with Kelly to become his wife, so your promise is now—"

"Well, sister… having a cow ogre colony and many brides is perfectly normal."

"E-Eh? Eh?"

"It's different from werewolves. …Your promise has no contradictions, does it?"

"E-Eh?!?"

"A-Ah, I see what you mean."

Werewolves apparently follow a monogamous system.
Even in Celesta, where polygamy is technically permitted by law, human society fundamentally upholds monogamy.
Linne, having moved directly from the werewolf colony to the human town, had not fully grasped this distinction.

"Nfu-fu-♪…Sister, we'll have many children with Brother Kelly!"

"…U-Um, yes, I suppose that's how it will be…"

"W-Wait, Linne… if it means nothing, we can just pretend it never happened."

"Brother Kelly. Werewolves' promises are absolute. I've already made my promise."

"…That's right. Since I made the promise, I shall become your wife. …And besides, having been shaped to match you like this, I…"

Shyly, Linne removes her armor beneath. Kate joins her in taking it off.
Linne is not wearing underwear; she couldn't wear any.
The thick, form-fitting prosthetic inserted between her thighs made it impossible.

"…There's no choice but to become your wife."

"…Ah, ah…"

Even though Kelly had rashly expanded his own desires and blamed others for them, he wouldn't normally be troubled by such things.
No, it was natural.
The joy of a male being asked to father children by these adorable wolf sisters left him no room to complain.

Kate happily but forcefully pulls the prosthetic out from between Linne's thighs.

"♪"

"A-Ah…! A-Ahh?!?"

A slurping sound echoed as a giant artificial phallus materialized. Upon closer inspection, it bore the carved face of an ox.

"……Who made this?"

"Sis~♪"

"……Y-yes… I've just… become like this…"

"…Isn't it cute?"

"But from today on, you don't need this anymore? Every day and every night, Big Brother Kelly will give you his cock?"

"Uuuh…♪"

The open vagina trembled with visible pleasure.

"…C-can I put it in?"

"Yes… b-but… since I've never had experience before… if possible, please be gentle."

"…I've only done it with Kate too, and I've lost my virginity for just a week now."

"Nah♪"

Amidst the joyful gaze of watching Kelly, his member was thrust into Linne's depths.

Given that he was slightly larger in build than Kate, he managed to swallow her vagina quite deeply, though not entirely to the very end.

Even so, Linne became intoxicated by the bliss of being pushed upward against her inner vaginal walls by the raw, hot flesh of his penis.

"A… aaah…♪ T-this is… Kelly-san's… phallus…♪"

"Cock~♪"

"U-uuh… Kate, that's embarrassing to say like that."

"Cock is cock, right?"

"But…"

"I get a little more excited when you call it 'cock' too."

"…O-okay… c-cock…"

"One more time."

"Cock. …Cock… Kelly-san's ox cock…!!"

"Hehe. Good."

"Cock… cock, good… give me more cock… fill me up with your cock… a-ahaha, yes, calling it 'cock' in such vulgar terms is actually wonderful…♪"

After being made to repeat it several times, Linne gradually became influenced by Kate's direct style of speech.

Her cheeks flushed as she slowly moved her body up and down, wagging her tail vigorously to display her pleasure. Thanks to his well-developed muscles from weight training, there was no pain; yet, overwhelmed by the sensation of such overwhelming vitality, she became increasingly immersed with every passing moment.

Although Linne had been an intellectual figure, once that image began to crumble, it dissolved quickly. As someone just like Kate in her youth, she adapted remarkably fast.

"Haa… haa… Kelly-san, more… fill me up even more… I'm so impatient… ruin me more… make me useless with your cock~♪"

"Oh, okay… here we go."

He wrapped both hands around her, gripping Linne tightly. Instantly understanding what was about to happen, Linne's eyes filled with anticipation.

"Uuuh…♪♪"

Juu, juu, jjuu…!!

With quick, forceful movements, Kelly seized Linne's body and began working his member inside her vagina. Due to the significant difference in their physiques, he had to control the motion carefully—not too deep, yet ensuring it wouldn't slip out—which meant he couldn't move himself but instead had to make her move.

And thus, Linne, whose body was seized and treated like a hole capable of swallowing only a phallus, tasted a pleasure from masochism unlike any she had known before. By utterly denying her strong self as an Ace Knight, she derived an intense state of ecstasy from being handled merely as a woman, a device for pleasure.

"Ahh, haaah! Yes, this is good... waaah, aaahh, aaah!!"

"Here we go... here we go, Linne, I'm going to cum...!?"

"Aaah♪... Yes, me, my... sperm, inside me... semen, fill me up, soak me... I'm pregnant♪"

"Uu, ku, uuuuh...!!"

"Aaaaaaaahhh!!"

He thrusts deep into her depths and ejaculates.

The vaginas of the sisters, though their overall atmospheres differ, are remarkably similar in appearance, and both seem to delight equally in Kelly's overwhelming flood of semen.

Shuddering, she sucks in the milky white fluid into her womb; the excess that overflows with a bubbling sound is licked away deliciously by Kate.

"Haa...♪"

"Mm, mm, Linne... it's such a waste...♪"

"Well, well, don't get too carried away, uuu... if you're so eager, won't you want to violate me again? Who knows who else might pass through this place?"

"I'll do it! I'll use my cock next after big sister, on you!"

"...Damn, this is endless, you know."

◇◇◇

Linne Mikagami. Height: 159 cm. Werewolf beastkin. Age: 19.
Passed the Ace Knight examination four years ago and was recruited. Currently serves as squad leader of the Third Infantry Regiment under the Western Legion.
She is renowned for her swift swordsmanship and martial arts, possessing a striking combat instinct when needed; however, recent assessments note growing concerns regarding her legs and stamina.
A few days ago, she submitted a request for transfer to the Northern Legion's "Second Crossbow Corps." At present, no record of that unit appears in official documents, as it is not listed among active forces, so her application remains pending review.
Suspicion also exists that she can no longer bear the heavy responsibilities of squad leader due to her youth; when suggested for demotion, she readily accepted.
For these reasons, upon rejoining the Crossbow Corps, she is scheduled to be assigned as a regular escort infantryman under direct command.
Final confirmation requested from Central Command.

◇◇◇

In the headquarters, Minister Sixth made a grimace.

"...Lately, there seems to be an unusual increase in women within Diane's unit. I recall that place was supposed to be organized exclusively by men."

"Oh, right, do you know about it, Minister? Rumor has it that Captain Diane has gotten a boyfriend or something."

"Mm, mm, regarding that matter... it feels like some kind of misunderstanding, or rather, things weren't clarified properly before I returned. What exactly was going on?"

"There's a man making the rounds in the rumors. He's said to be an extreme womanizer. For some reason, reports from Special Captain Becker claim he's been luring numerous demi-humens."

"Mm, that bastard's doing it!"

No, that's not true.

(TBC)

It has been a week since Kelly reunited with the wolf girl Kate.

"Of all people, that imp Kelly had to hook up with a werewolf beastman..."

"Don’t call him an imp, at least say something like 'wimp' or something."

"I always thought he woke up to men in the city."

"According to my husband, he was taught enlightenment by some great monk."

"Or maybe since that time when he got a spear through his eye in Hell’s Boar, it’s been too painful to get hard."

The catty gossip among the female cow ogres is pretty frank.

Unaware of any such rumors, Kelly was living a blissful life.

"Mmm... Zzz..."

"Sniff... You’re sleeping so well. Kelly-nii-chan, it’s morning..."

Kate licks Kelly’s cheek affectionately. Kelly doesn’t wake up.

Kate giggles at his inability to wake up and gently pulls the blanket off him.

Kelly’s violent stiffness greeted the morning.

“Aha.”

After being momentarily captivated by her bold figure, Kate grabbed it with both hands and began licking the underside of the tip.

Kelly still wasn’t awake.

“…Kelly-nii-chan, it’s morning. Morning. It’s time for me to suck your dick again…♪”

She whispered in a voice that was unclear whether she wanted to wake him or not, then rubbed her cheek against Kelly’s morning erection before slowly removing her loincloth. She wasn’t wearing underwear anymore. She’d already lost interest in doing so.

“It’s your fault for not waking up, Kelly-nii-chan…♪”

Then, using both hands to spread her labia as far as they could, she impaled herself on Kelly’s cock. The size difference was painful, but her expression remained playful.

“Mmmph… Goh… goh… ugh?”

“Ahh, you’re awake…?”

Just as the tip reached halfway—meaning it had reached deep inside Kate—Kelly opened his eyes with a heavy sigh.

What he saw was the wolf girl, wearing nothing but her underwear, sitting on top of him, smiling as she swayed her hips like a toy.

"O-oh? What’s this?"

"Morning, Onii-chan. We’re gonna do it a lot today too, okay~♪"

"...H-hey, hey. Didn’t we do it like, non-stop from morning to night yesterday?"

"I’m hungry. No matter how much I eat the day before, I still get hungry in the morning, you know?"

"N-no, if you’re hungry, just tell Mom—"

"It’s not my stomach! It’s inside me~!"

Kelly slumped over in exhaustion.

"...You’ve got some weird sense of humor. Who taught you that?"

"It’s Dorothy Onee-san’s signature humor, they say."

Her mother’s outrageousness was giving him a headache.

He glanced at the doorway and saw his mother peeking around the corner. Realizing Kelly was staring, she gave him a thumb-and-forefinger "OK" sign before retreating.

"Mom... even if you’re desperate for grandkids..."

"Let’s make a baby. I’ll work hard on it. Here, here, Onii-chan, I’ll start making the baby first thing in the morning. It’ll be good for your health."

"You…"

Kate waved her hands forward energetically. She could do the insertion part herself, but she couldn’t yet do the piston motion.

So, she gestured with her hands, saying to grab her and move up and down quickly.

"If you put it in, there’s no way I won’t have to finish…!"

"I’ll finish. I’m full of energy today too, thanks to all the baby-making♪"

"I don’t even know what you’re talking about…"

As she was asked, Kelly began to take Kate’s request seriously. Kate wagged her tail with an innocent smile. The Isaac household had already become quite lewd before noon.

Wake up, have sex with Kate, play with the kids, have sex with Kate, go fishing or hunting sometimes, have sex with Kate, drink with the group, get a bit tipsy and have sex with Kate, wash off at the water’s edge before bed while having sex with Kate, and then fall asleep while having sex with Kate.

"What kind of life is this?"

"Wolf beastmen, all newlyweds are like that, right?"

Kate looked at him curiously.

"I mean, even an ox ogre is like that with a hot couple."

Dorothy nodded solemnly.

"That’s not good for the kids’ education, is it?"

"I was actually regretting I should’ve done a worse job of educating them."

He was the record holder for the longest virginity streak in the ox ogre colony.

"But still… I’ve got to go back to Bussom in about two weeks, so I shouldn’t get used to this kind of thing."

"Quit the military already."

"I don’t mind going back. I’ll go to Bussom too. Wolf beastmen, I promise. Absolutely. I’ll be your bride, brother. We can’t be apart again."

"Well… even if you say that, there’s no women in the barracks…"

He remembered one person who’d been brought along and felt a little gloomy. It wasn’t as bad as Anzeros, but Kelly was also pretty strict about discipline.

Or rather, in Kelly’s case, it was just that he found the barracks, with hardly any interaction with women, to be oddly comfortable, like a boys’ school.

"Everything’ll work out. It’ll be fine."

"Everything's fine, everything's fine, everything's fine~♪"

"Yeah~♪"

Dorothy and Kate exchanged a high-five with a height difference of nearly 60 centimeters. The scene was somewhat reassuring since there didn’t seem to be any potential for a mother-in-law versus daughter-in-law conflict, but Kelly, who was surprisingly serious, couldn’t help but worry about what would happen next.

Getting married to Kate was fine. She’d take responsibility. She’d already made up her mind.

It was just a matter of whether she should stay or go. But she still didn’t want to leave the military. At the very least, she wanted to see how things went until they promoted someone like Arnie to regular soldier status.

While pondering this, Kelly strolled leisurely through the evening labyrinth.

In her hand was a dwarven-made greatsword forged from desert steel. For humans, it was a massive weapon that required all their strength just to lift, but for Kelly’s massive frame, it was about the size of a regular middle-sized sword.

It was a keepsake from her father. Perfect for hunting Hellboar.

And then.

"Kelly Isaac, regular soldier... no, Ten-Man Leader, is that right?"

"Ah?"

From the corner of the labyrinth, a figure emerged, swaying slightly.

The atmosphere was tense, but there was no immediate sense of hostility. While mentally bracing herself, Kelly casually turned her head.

Light armor and a cloak. A longsword at her waist. Her neatly tied hair swaying gently as she glanced around with a dignified gaze.

At first glance, it was clear she wasn’t a resident of the desert dungeon right now. She was a soldier.

"Who are you?"

"I’m Lieutenant Rinné Mikagami of the Third Infantry Regiment of the Western Army."

"The Western Third Infantry… Mikagami? You’re that old man’s grandson?"

"Yes. I’m his granddaughter. We’ve met before."

The Third Infantry Regiment of the Western Army was known for its elite status. Having repeatedly clashed with the Afilm Empire, the region’s current largest threat, they were highly experienced in combat, especially in terms of the ratio of ace nights.

Moreover, the distinctive surname "Mikagami" was only seen among wolf beastmen in this dungeon. As expected, she was Zenga Mikagami’s granddaughter—one of Kate’s sisters.

However, there was no trace of the foreign, unstable demeanor that Kate had exhibited. She spoke standard Japanese fluently.

"Do you know any of my sisters?"

"Yes."

"Indeed. …I have been looking for you."

"I heard."

"...Is she still insisting on becoming your wife?"

"Yes."

"…………"

Linne shook her head, as if troubled.

"That girl is stubborn."

"...What? Could it be…"

Suddenly, he recalled a possibility he had once considered.

Could it be…

That she might have misunderstood and believed in a promise that had never been made?

Linne smiled.

Do not be concerned. I have made a promise. A promise that is absolute for us.

"...I see."

"But with this tongue, which speaks of absolutes, I humbly request something."

"?"

"I wish to have it annulled."

While Kate was basking in the sun, Kelly had gone out hunting.

Kate, feeling lonely and sulking, eventually couldn’t hold back for more than ten minutes and followed Kelly into the labyrinth.

As she ran chasing Kelly’s scent, she came across a familiar smell—no, it was the scent of someone she’d parted ways with about ten days ago. Instinctively, she hid herself.

Her sister was there.

Her sister was standing quietly facing Kelly.

"Wolf beasts honor their promises. A race that would spend a lifetime or even gouge out their own eyes for the sake of a promise. It is indeed a virtue, but because it is such an unarguable virtue, they do not hesitate to sacrifice everything—heart, happiness, even themselves."

"…………"

"That child made a promise too soon, a promise that was far too big. In her effort to keep that promise—to become your wife—she has grown up without ever knowing love."

"Without... knowing love?"

Now that I think about it, Kate had been clinging to Kelly with almost fanatical devotion. It felt less like love and more like a kind of blind faith.

"I want my sister to understand what it means to love someone. I don’t want her to spend her life devoted to this promise until she’s consumed by it. I want her to have a rich, fulfilling life."

"...I see. ...Well, I guess there’s no helping it."

Kelly spoke with a sensible tone.

As he spoke those sensible words, he never imagined he’d once again feel the pain of losing someone he thought was within his grasp.

(…Again, huh?)

Indeed, I don’t think it’s fair for Kate to remain blindly devoted to Kelly.

But thinking about it now, the idea of letting go of a woman he’d believed he could reach feels like the world is closing in on him once more.

"I thought as much."

To his relief, Linne nodded with an almost irritatingly calm expression at his strained words.

"Yes, I suppose so. That girl is a bit too straightforward, which can be both endearing and frustrating…"

Kelly didn’t hear Linne’s words. She didn’t want to hear them. She felt like retreating somewhere and crying for a while. Maybe she should just quit being a soldier altogether, she thought in a self-destructive mood.

And it was precisely because she hadn’t listened to a single word of Linne’s conversation that she managed to make it in time.

"…!!"

The ceiling of the labyrinth trembled slightly.

The air rippled faintly. The atmospheric pressure shifted.

A presence, one that wasn’t just that of a Hellboar—something far more powerful.

"Hyaaaaaah!!"

There was no hesitation. Thanks to not spending even a moment on her conversation with Linne, she managed to throw the greatsword behind Linne at the perfect moment.

Thud!!

"Oooooohhh!!"

"Wha—!?"

Linné’s ears twitched sharply, and she turned around in a panic. Behind her stood a massive stone figurine, easily twice the size of Kelly, about to fall.

“What…!?”

“You’ve been followed. You probably took shortcuts from the labyrinth near Quica to get here.”

“Yes… yes.”

“It looks like you stepped into the stone figurine’s sensory range.”

Kelly quietly gathered her strength as Linné braced herself, keeping an eye on her.

Kelly's usually dark, piercing eyes now shone with a golden radiance. The frustration, the frustration born from unyielding despair, was awakening the untapped strength of the bull ogre slumbering within Kelly for the first time in a long while.

The stone doll stood up.

It clumsily but forcefully tried to pull the sword embedded in its chest.

"BOOOOOOOOOOOOOOOOOOOO!!"

With golden light emanating from its eyes, Kelly released the tension in its entire body and leaped into the air. It kicked off the high ceiling and used all its weight to kick down the hilt of the sword embedded in the stone doll's chest.

The stone doll's chest split vertically. Kelly caught the spinning greatsword mid-air like a whirlwind, then slashed horizontally across the right leg of the stone doll.

!!

In a single, clean motion, she split it cleanly in two with her thigh.

The rock doll lost its balance. There was no need to wait for it to fall. Kelly swung her thick leg, sending a whirlwind through the labyrinth as she unleashed a roundhouse kick.

"FUGOOOOOOO!!"

Thud!!

The rock doll stumbled and fell.

She forcefully drove her sword into its head, pinning it to the ground.

"I-Impressive..."

"BUMOOOOOA!!"

"Kelly-dono!?"

Kelly brought her fist down with a single motion.

She kicked it.

I grabbed the broken leg of the golem and slammed it down.

With each strike, the rock was literally shattered, and in an instant, the stone golem began to fall apart into scattered boulders.

The special potential of the bull ogre.

In a labyrinth—meaning a closed space filled with darkness—the bull ogre could dramatically increase its combat power.

Born as the ruler of darkness, the bull ogre, optimized for underground dominance, could gain attack capabilities double that in ordinary times.

"Though, I’ve heard that bull ogres have gotten too accustomed to peace, so they can’t unleash this kind of reckless strength unless they’ve been properly trained for combat. I’ve been hunting since I was a kid, risking my life, so somehow… I ended up like this."

"So that’s how it was?"

"It’s no surprise that I could break through the Rock God Labyrinth. It’s the bull ogre’s specialty. In a Trot-style tournament, I wouldn’t have been able to do it."

"…………"

"I remembered now. You were there back then…"

"Yes."

Linne was taking the Ace Knight exam alongside Kelly at the time.

And then... I was surrounded by dead bodies and stone dolls, on the verge of death.

Kelly couldn’t bear to watch and saved Linn. That was originally against the rules, and it cost Kelly his chance to compete.

"During that time, I got used to handling things while keeping an eye on Kate. When I heard about the Ace Night exam being open to newcomers, I got cocky thinking I could bring honor back to my hometown and ended up taking it... That’s when you saved me."

"…………"

"Why did you give up on becoming an Ace Night?"

"...If helping people would get me disqualified, I figured I wasn’t cut out for it."

Rules are rules. I know that.

But if the same situation comes up again, Kelly would do the same thing. It’s the same as before.

And then Kelly realized... He was spurred on by the surroundings, but deep down, he didn’t want the honor of being an Ace Night. All he wanted was to help his comrades.

"I just want to protect my comrades. A crossbow is perfect for that. I can even save comrades from far away. That’s why I decided to focus on the crossbow unit."

"...I see. I thought we’d meet again... So I took the Ace Night exam the following year, and here I am now."

The chest of his leather armor was engraved with the Ace Night insignia.

"And the elite Western Third Infantry. Not bad at all."

"I, too, have gone astray."

"…………?"

Lynn stood in front of Kelly, who was sitting down, and began removing her armor.

Kelly was wearing a long-sleeved, knee-length underarmor, so there was no issue, but she felt a little embarrassed and looked away.

"If you break your promise, Kate won’t accept it."

"Huh? Wait, what—"

"Wolf beastmen’s promises are absolute. The only way to nullify such a promise is through another wolf beastman’s promise, or nothing else."

"Is that so?"

"Yes. So, please make a new promise with me. That way, I can set Kate free."

"…………"

She felt incredibly lonely. If she said "yes" now, her close relationship with Kate would end.

For a moment, the thought crossed my mind that perhaps if I threw a tantrum now, it might still be enough to save us. But I couldn’t bring myself to act on such selfish desires—Kelly, the cowardly and calm one, talked me down with a firm voice.

Whether she knew or not of Kelly’s lonely struggle, Linne smiled softly and began to speak slowly.

“I want you to make me your wife, Kelly Isaac.”

“…………Huh?”

“Ever since that day, I’ve been waiting for our reunion. I’ve kept the feelings for you warm in my heart all this time. ……This is a bond without promise—a real love. Please let me become your wife so that someday I can make that same experience yours too.”

“…………”

I couldn’t quite grasp the point. Kelly’s face turned completely blank.

Then, he noticed something moving in the corner of his vision and, with his characteristic squinted eyes, focused intently on it.

It was Kate. She had been hiding in the shadows until now.

Kate raised her fist. It was a signal—“Go on, Kelly-nii-chan, go for it.”

(……Is this really okay?)

Unable to keep up with the confusing situation, Kelly hesitated. And as Linne’s eyes began to look anxious, he panicked even more.

"Am I... not enough?"

"...W-well..."

"Ahh, don’t worry about the night. I’ve been... training myself to accept your manhood. If you’d like, I can show you proof right now."

"…………"

Kelly broke into a cold sweat. Was this the same way Linne had walked around with that thick bulge in her pants, looking so cool?

Then Kate made the same gesture again. Hurry up, hurry up.

"...Got it."

"I’m glad...♪"

Linne kissed Kelly deeply, burying her nose and mouth in her large lips, just like Kate had done.

"The promise is now complete. With this..."

"Yay!♪"

From behind, Kate suddenly leaped onto Linne. Surprised.

Sister: "Onee-san, you’re going to marry Onii-chan and be his wife!"

User: "N-no! Kate, listen to me!"

"I’ve already made a marriage promise with Kelly-san, so Kate, your promise is no longer—"

Sister: "You see, Onee-san… The cow org colony has plenty of wives, it’s normal."

"It’s different from werewolves. …Your promise isn’t contradictory, is it?"

[Ah]: "Ah, I see, that’s how it is."

It seems werewolves are monogamous.

And while Celesta allows polygamy in theory, the human society adheres to the principle of one man and one woman.

Lynn, who had moved directly from the wolf beastman colony to the human town, hadn’t fully understood it yet.

"Nfufu~♪ …Onee-chan, together! Kelly-nii-chan’s children, lots of them!"

"...Uu, yes, I’ll... end up like that, won’t I?"

"Hey, Lynn... If there’s no meaning, then maybe we can just pretend it never happened."

"Kelly-nii-chan. Wolf beastmen, promise, absolutely. I’ve already made a promise..."

"...That’s right. Since I’ve made a promise, I’ll become your wife. ...And since I’ve become like this to match you..."

Lynn shyly took off her underarmor. Kate also took it off together with her.

Lynn wasn’t wearing any underwear. She couldn’t wear it.

It was because of the thick, oversized prosthetic that had pierced through her crotch.

"...I have no choice but to become your wife."

"...Ah, yeah..."

Normally, if someone got ahead of themselves and then blamed others for it, it’d be a problem, but Kelly somehow couldn’t bring himself to complain about it.

No, of course not.

The joy of a male being teased by such adorable wolf sisters silenced any complaints.

Kate happily and forcefully pulled out the prosthetic from Linn’s crotch.

"♪"

"Ah, ah… ah, ahh!?"

With a slurp, the massive fake phallus revealed itself. Upon closer inspection, it had a cow face carved into it.

"...Who made this?"

"Onee-chan♪"

"...Y-yes… I just… got carried away…"

"...It’s cute, isn’t it?"

"But from today, you won’t need this anymore, right? You’ll get to have Onii-chan Kelly’s dick every day and night, okay?"

"♪"

I could clearly see her opened vagina trembling and enjoying herself.

"...Is it okay if I... put it in?"

"Yes... um, well, I’ve never done this before... so please be gentle."

"...I’ve only done it with Kate too, and it’s been just a week since I lost my virginity."

"Yep♪"

Under Kate’s joyful gaze, Kelly’s member pushed its way into Linne.

Being slightly larger than Kate, Linne managed to take in more of Kelly’s cock, though not all of it.

Still, the pleasure of having her deepest part filled with the hot, living flesh intoxicated her.

"Ahh...♪ This is Kelly-san’s... his penis...♪"

"His dick♪"

"Ugh... Kate, that’s embarrassing to say like that."

"It’s just a dick, isn’t it?"

"But..."

"I also feel a little more excited when you say 'penis.'"

"...O-okay, um... p-penis."

"One more time."

"Penis... penis... Kelly-san's cow penis...!!"

"Uho. That’s good."

"Penis... penis is good... do more penis... use your penis to fill me up, lots and lots... ah, haah, yes, using the word 'penis' in a crude way is much more exciting...♪"

As she was repeatedly told, Linne gradually became immersed in Kate’s direct, blunt way of speaking.

Her cheeks flushed red as she slowly moved her body up and down, wagging her tail to express her pleasure. Having been trained with a firm touch, she felt no discomfort, but the overwhelming sensation of life force made her grow more and more captivated with each passing moment.

Linne had always been seen as a rational person, but once she started to unravel, it was quick. Being young like Kate, she adapted quickly.

"Ha... haa, Kelly-san, more... do it harder, fill me up more... I’m so frustrated, make me lose myself, make me lose myself with your penis♪"

"Oh, yeah... here we go."

I tightly gripped Linn with both hands, enveloping her. Linn instantly understood what was coming and let her eyes drift in anticipation.

"♪♪"

S-s-s-s...!!

Kelly began stroking his member inside Linn’s vagina, gripping her body in small, yet powerful movements. The large difference in their sizes made it impossible not to move too quickly or too deeply without pulling out, forcing him to focus on the woman rather than himself.

As Linn was held and treated like a hole meant only for his member, she experienced an unparalleled pleasure of submission. She completely rejected her strong self as AceNight, being reduced to just a woman, a pleasure device, and felt an intense sense of ecstasy.

“Ahh, hah, ahhh! Yes, this, yes… wah, auu, auu!!”

“I’m coming… I’m coming, Linn, I’m going to cum…!?”

“Auu♪… Yes, I-I’ll… my cum… inside me… fill me up… impregnate me… I’ll get pregnant♪”

“Ugh, ugh, uuu…!!”

“Aaaaaahhh!!”

He thrust into Linn’s depths, cumming violently.

The sisters, though with different personalities, shared similar vaginas that equally enjoyed Kelly’s massive release of semen.

The trembling child sucked the white fluid into her womb, and Kate licked up the excess with a slurping sound.

"Haa…♪"

"Nn, nn, I can’t hold it back…♪"

"Well, not so much, ugh… If you keep doing that, I’ll want to do it again, and who knows who might come by here!"

"I’ll go next, after Onee-san’s turn!"

"Man, you’re bottomless, huh?"

◇◇◇

Linn Mikagami. 159 cm tall, a wolf beastkin. 19 years old.

She passed the Aces Night examination four years ago and was hired. Currently serving as a corporal in the Western Army’s Third Infantry Regiment.

She was renowned for her fast swordsmanship and martial arts, and her combat instincts were nothing short of astonishing, but there were also reports that she had been feeling pain in her legs and hips lately.

Several days ago, she submitted a request to transfer to the Northern Army’s "Second Crossbow Corps." The relevant documents have not been found, and since the Crossbow Corps is not listed as part of the combat force, the request has been put on hold.

It was also suspected that she couldn’t handle the weight of being a corporal due to her youth, and when it was suggested she be demoted, she readily accepted.

For the above reasons, once the crossbow unit is reinstated, they are expected to be reassigned as regular infantry guards.

Seek final confirmation from the Central Command.

◇◇◇

The Sixth Minister made a grim face at headquarters.

"...Lately, hasn’t there been an unusually high number of women in Dianna’s unit? I’m pretty sure it was originally supposed to be all-male."

"Oh, by the way, do you know something about this, Minister? Apparently, Dianna’s Centurion has a boyfriend or something like that."

"Hmm, well... about that... I think there was some misunderstanding or confusion when they returned, but I’m not entirely sure what happened."

"There’s this guy going around. Rumor has it he’s quite the playboy. Somehow, he’s been hooking up with a lot of demi-humans. According to Captain Becker’s report."

"Hmm, could that be his doing?!"

No, it’s not.
