Beastmen are highly susceptible to the phases of the moon.
Especially their physical abilities and sensory powers change drastically at night, peaking with mental exhilaration to nearly double their usual capacity.
Needless to say, this is at its maximum during a full moon and most subdued during a new moon.
By the way, Orcs also react to the lunar cycle, though not as strongly as Beastmen.
This is a common trait among races suited for darkness—not just Orcs, but also Dwarves and Dark Elves—and they become most active during a new moon.
The closer they are to darkness, the stronger they get. Even those without night vision struggle against these denizens of the dark, who exhibit abilities beyond their normal capacity.
This is why the night raid tactics favored by the multi-ethnic nation of Celesta and the Dwarven kingdom of Goth in the southern continent have long been feared. Neighboring countries have established schedules to reinforce their borders, especially during new moons.
Now, these traits obviously relate to reproductive capabilities.
When races with these subtly opposing characteristics get together, it can lead to some troublesome issues.
“Kelly, you good?"
"Ugh… yeah. And you two, maybe ease up a little? I’m not exactly young anymore."
"You’re still in your twenties; don’t use age as an excuse! …Did it happen somewhere else?"
"No way! Orcs get sluggish during a full moon!”
The Wolfkin sisters, Lynne and Kate, licked the softened shafts with relish.
Kelly and Isaac were puffing out their cheeks, overwhelmed by the two women’s libido.
”Seriously, one hour every waking moment from morning till night isn’t exactly… cultured…”
He pulled away from the still-desperate pair, wiping his groin with a damp hand before pulling up his pants and trousers. If left unchecked, they’d relentlessly keep licking him until he was hard again.
”If it were up to me, I wouldn’t mind being stuffed all day long…"
"Sis, that’s cheating! Then I won’t get any!"
"Yeah… Besides, Kelly-san has a life too."
"You two should go outside wearing clothes once in a while… Seriously, waiting for my dick in your room all day?”
Lynne tugged at the sheets and grinned mischievously, while Kate wagged her tail happily.
”Because we love Kelly-bro!"
"W-well… I’m still not used to dicks, so, if possible, a little more would be nice. Especially during full moons, my body craves it, so getting used to it now is important."
"That’s what I’m saying… sigh.”
It’s great that they’re happy, but maybe they’re a little too into it.
Lynne had rushed back to Quieca the night she made her deal with Kelly and submitted a transfer request. For a normal human, it would take over a month one way, but using the Desert Labyrinth to its fullest extent, she’d made the round trip in just ten days.
Even with the shortcut, that was astonishing mobility for a Wolfkin.
”I wanted to see Kelly-san so badly, I ran without stopping!"
"…That’s why I told you not to drag three stone golems along!”
It had been since the Ace Knight exam that Kelly had faced that many stone golems at once, but somehow, with Lynne’s help, he managed to repel them.
He realized then just how strong Lynne was—no wonder she was highly regarded in the Western Third Infantry Regiment.
Her main strength lay in her powerful legs and body techniques, but she wasn’t clumsy with a sword either. She even managed to sever an arm off one of the stone golems with what looked like an ordinary longsword.
”…If you put in the work on that side, becoming a Master Knight isn’t just a dream."
"But right now, I’m Kelly-san’s wife! ♪”
Three days ago, I completely ignored my travel fatigue and the afterglow of battle, and in a corner of the labyrinth where five stone dolls were scattered, I suddenly jumped on Kelly and demanded another round of reunion sex.
“Man, I gotta head back to Basson in like, what, three more days?"
"…That’s a shame."
"I can’t get any action until I get there…”
The wolf sisters perked up their ears.
Swing! The door burst open.
“You quit the army, huh?"
"Mom!”
Dorothy gave the thumbs-up with her pinky and thumb.
“Now, now, it ain’t like you’re some hired hand who can just waltz in and out whenever you feel like it! The army’s not that kind of place!"
"If you just ghost on them, they won’t even come looking for you, right? Besides, nobody knows about our colony anyway."
"Well, we did put up the Centurion and Smisson the other day."
"They’ll understand, right?"
"On what basis!?”
Mom was already in full-on ambition mode for the grandkids. Since Kate and Linne made that “marriage” promise with Kelly, they were completely obsessed with making babies.
“I wanna work in the army for at least three more years…"
"Three years in the army…"
"By the time I get back, you two will have combined to make a family of fifteen!”
Wolf-people usually give birth to twins.
“What should we do? Does Basson even have daycare?"
"Nope…"
"It’s all good, it’s all good—I’ll take care of them in town."
"Oh my, if one of you goes into labor, send a letter, and I’ll come help!"
"Wait, both of you. And you too, Mom. Are we definitely going to go all out on the baby-making?”
Kate nodded enthusiastically. Linne looked away, blushing.
”…U-um… well, probably, even if we don’t think about it, we’ll just keep getting pregnant every year… and, uh, I don’t think we can stop doing the thing with Kelly."
"Yeah~!"
"Yep."
"That’s reassuring as all hell.”
Mom joined in the nodding.
”…Um, well…”
Kelly was left out in the cold, feeling a little lost.
If it were someone else, she’d be thrilled at the thought of a harem of sisters making babies, but when women gang up like this, they become completely uncontrollable.
Smisson must feel so left out too, Kelly thought with a twinge of sympathy, being liked by Seren and the Centurion.
But really, it was just that Kelly was a hopeless pushover when it came to women.
“Even so.”
“First—"
"Yes.”
At dinner, Dorothy slammed her hand on the table, making Kelly jump.
Kate and Linne stared up at Dorothy with puzzled expressions, wearing Dorothy’s old shirts (loose as hell, but their own clothes were ruined from getting soaked in fluids during sex).
“Isn’t it pathetic that even though these girls are so eager to do it for you, you’re pulling a ‘no-go’ just because it’s a full moon?” Dorothy asked.
“Well, Mom, you’ve gotta understand—”
“It’s not about understanding! These fine ladies are practically begging to stretch their pussies for your kids—doesn’t a real man get his dick hard even at death’s door? One or two stiff ones, right?”
“Mom, this is dinner time—try not to be so vulgar.”
“BUT—”
Bang, bang, bang! Dorothy hammered the table.
“I paid through the nose for a ton of Hell’s Bore livers.”
”…Ugh.”
“Huh? Kelly?”
“M-me, I don’t like offal.”
The colony’s strongest bull, despite his many dislikes.
“Enough!”
Dorothy wouldn’t listen.
She plucked a raw Hell’s Bore liver, grabbed Kelly’s chin, forced his mouth open, and shoved it in.
“B-Bloody hell!?”
“They said eating this fresh and raw would give even a seventy-year-old the energy of a stallion—Kelly, this’ll make you two—” Ah! “Don’t puke!”
“I-Ick, I don’t like it!”
Kelly’s eyes welled up with tears.
But Kate caught the vomited liver in her mouth.
Then she tried to feed it back to Kelly.
“K-Kate!?”
Kelly’s eyes brimmed even more. He could shove her away, but that’d be the worst thing ever.
“Ugh…”
“Mnng…”
He ended up eating it from Kate anyway.
And Kate pressed her face into his mouth, not letting him spit it out.
”…Guh.”
He swallowed it.
“T-this is insane. So insane.”
“Here, next one.”
“I can’t take it anymore!”
But before Kelly could even finish, there was Kate, still gnawing on the next piece of liver, and Linne, mimicking her, trying to pinch and stuff another piece into her mouth.
“BLEH!!”
She ate it all while crying.
“Ugh… ugh, I thought I was gonna die…”
Kelly washed her mouth out, sobbing uncontrollably—like a maiden who’d just had her innocence violated.
But even as she did, changes were happening to Kelly’s body.
“Ugh… damn it.”
Kelly’s cock was swelling rapidly.
And with it, her libido began to overwhelm her thoughts.
“Ugh…”
Kelly shook her head.
She wanted to cum for Kate and Linne. She wanted to do whatever she pleased with them.
If this were the virginal Kelly of a few weeks ago, she might have been able to resist. But Kelly had already tasted women.
She knew where her libido could go.
And once that happened, there was no other way to sublimate that heightened lust.
Even if reason was satisfied, instinct demanded more.
“Ugh… o—ohhh.”
Kelly slowly stood up, looking down at Kate and Linne, who were barely taller than her waist.
She met their expectant gazes…
…And with a gnash of teeth and a puff of hot breath from her nose, she roared:
”…Y-yes… y-you let me do ittt!!”
The last remnants of her reason reached out to them in a voice that even surprised herself.
“Waaah!”
“Au… Ke-Keeriiisaaannn!”
She grabbed both of them, flipping each one over so their bare, pantiless butts hung free.
With her right hand, she forced her throbbing cock—peeking out from the edge of his pants—into Linne’s snatch.
“Haaaaa…♪”
Linne stuck out her tongue, moaning in pleasure as Kelly brutally spread her tight little folds to accommodate his thick shaft. Linne had also eaten a bit of liver earlier, and with the full moon’s effect, she was in an intense state of heat.
Kelly plunged into her depths in one swift motion.
But even then, it was only halfway. Kelly’s long, thick cock couldn’t go any further.
With reason completely gone, Kelly pulled out in frustration, slamming his hips back against Linne’s cunt with forceful thrusts.
It was pure, self-serving masturbation—using Linne’s body as nothing more than a tool for his own pleasure, completely disregarding her comfort.
But that was exactly the kind of masochistic sex Linne loved.
“Haaah, aggh, ahh! Keeriiisaaan, Keeriiisaaan! More, morettt! Harder… ahhh!!”
I am completely under the control of this strong, fierce man.
My worth now isn’t that of a proud warrior or a righteous lycanthrope, but merely a woman, merely a cunt, merely a hole to rub his dick against.
Lynne was overwhelmed with ecstasy by being treated like this and impregnated.
Kelly was the one who satisfied her on a primal, animalistic level, and this brutal sex he performed while aroused was exactly that.
“Uwah, aah, wau, uwu… Ke- Kelly-san, chinko… I love your dick… I’ll love your dick forever… I’ll be your dick hole for life!!”
“Bumooooh!!”
Kelly wasn’t listening. No “promise” would stand.
If Kelly affirmed this here and now, she’d abandon her position as a soldier, her role as an older sister—everything—to become nothing more than a sex slave beyond the title of wife, for all eternity. Lynne burned that much for Kelly, had surrendered so completely to his cock, felt such love.
“Kelly… saaan!!”
And with no regard for Lynne, Kelly ravaged her cunt as he pleased, then shot his load deep inside her womb.
“Ahh… aghh♪ Kuaa… uwuuu!!”
After a relentless mix of pain and pleasure, Lynne was driven to climax by the mercilessly unleashed seed and fainted.
Even witnessing Lynne’s ravaged state, her sister only sparkled with delight.
She was already used to Lynne’s kinks, Kelly’s size, his ferocity—none of it was frightening anymore. The more days she’d spent fucking Kelly like crazy, the more Kate surpassed Lynne in depravity.
“Hauuuu♪”
As if his business were done, Kelly pulled his cock from Lynne and shoved it into Kate.
Lynne was tossed onto the table with a thud. A few seconds later, she opened her eyes slightly, felt the seed overflowing from her crotch, and smiled faintly.
Meanwhile, her sister was being used as Kelly’s masturbation tool just like her older sister.
“Gahf, ahf, auh, kahf♪ ……Keri, Onii-chan, su-goo… iiii♪”
Her cunt’s depths were greedily devoured in a rhythmic assault, and Kate wagged her tail in delight.
It looked like brutal, destructive sex. In fact, most of her reason had fled, and Kelly wasn’t considering Kate’s comfort at all.
But still, he retained just enough control not to break her. No matter how much he followed his instincts, Kelly’s kindness toward the weaker opponent remained.
That was so endearing that Kate, even while restrained and unable to move freely, desperately wagged her ass to help Kelly reach climax as little as possible.
“Bugoohooo!!”
Feeling that, Kelly groaned low, as if resisting pleasure.
“I-it’s okay… Onii-chan, you can cum… any time now♪”
“Uugghooo!!”
A small lycanthrope wagged her ass, urging the massive bull ogre to climax.
More than lust, her expression was drenched in love, and her movements…
In the end, Kelly’s beastly nature succumbed to it.
“Bumoooooh!!”
With a death cry-like roar, Kelly shot his load generously into Kate’s earnest cunt.
“Haa… seeing it up close is something else.”
Dorothy watched in awe.
The lycanthrope sisters lay collapsed on the table, panting as seed dripped from their crotches.
And her son was still hard, rock solid…
”…Kerry? Kerry, wait a— Ah! Damn it!”
Kerry woke at dawn.
She couldn’t remember where she’d lost consciousness. Even after reason fled, her memories remained. She’d fucked Kate and Linne in the dining room, and then…
And then…
“Huh?”
She sat up abruptly, only to see three women sprawled out.
Kate, Linne, and Dorothy.
“What the—!?”
Dorothy was naked too, her thighs slick with semen.
“W-What the hell…”
Kerry’s eyes were brimming with tears.
“U-Um… you’re awake, Kerry.”
“Mum.”
”…I can’t believe I got screwed like that by my own son…”
“I’m so sorry, I’m so sorry.”
“Ugh… if it was on purpose, I’d kill you. But hey, it’s a full moon, so no pregnancy worries.”
Dorothy staggered to her feet, draping cloths over Kate and Linne before giving them a slightly gentle look.
“Still, shouldn’t these girls get proper, tough Orc or Bull Orc husbands for their own safety?”
“T-That’s just cruel to the women who’d be added as wives!”
“A mother who gets screwed due to excess momentum isn’t pitiable?”
“I’m so sorry, I’m so sorry.”
Dorothy, still hot at almost thirty with a kid, was quite the sight, but Kerry decided it was best left unsaid.
She’d just be labeled a hardcore momma’s boy. She couldn’t live like that.
”…But it feels good after such a long time, doesn’t it?”
“Don’t say things I can’t answer to, Mum.”
“Ahahaha. Well, Orc women don’t care much about that sort of thing.”
“I don’t want that either.”
“How about one more go? Just because of the momentum thing?”
“I’m so sorry, I’m so sorry.”
It was dawn, and another reason why Kerry Isaac couldn’t defy the strongest man in the Bull Orc Colony had been added.
