It had the color of a pale, translucent skin.

The part that swelled out like the tip of a baby bottle cap was designed to hold semen after ejaculation.

You place it against the tip of the rod and skillfully roll the coiled sheath down; it’s the mechanism by which the contraceptive covers the shaft.

It is, in other words, a condom.

Incidentally, since there’s no plastic involved, you won’t find any square packaging like those seen in pornographic books.

It felt a bit disappointing to him, but he decided it was fine as long as he could generate the essential contents.

Since it was placed directly from the 『Inventory』, there were no hygiene issues either.

With his hands trembling from excitement, he carefully attached it.

“...Sō-kun, are you used to putting them on?”

Chiya sent him a look of suspicion, so he decided to be honest to clear up the misunderstanding.

“I... practiced in secret so that I wouldn’t mess things up when we do it.”

“Practice? Is the punchline that you did it with another girl?”

“No! Not at all... It was just me, alone.”

His face burned hot with shame.

Seeing me in such a state, Chiuyu’s lips twitched into a small smile.

"Such a cutie," she murmured.

"..."

"It's okay. I've done plenty of practice imagining my virginity lost, so we're on the same page."

As she spoke, Chiuyu gently lifted the hem of her skirt.

Her hidden part was exposed to the air.

Small, tightly sealed, and smooth, that spot was proof of an impenetrable gate that had never allowed a single intruder before.

And now, reflecting the lantern light were the viscous drops of fluid oozing from the entrance to that gate.

I couldn't help but swallow hard.

"...It's embarrassing if you keep staring like that."

"S-sorry. But it is my first time really seeing up close..."

We had touched each other many times before, but this was the first time I was looking at her from such a close distance.

"Sucha... don't rush me any more than this."

"I got it, I'm sorry."

I placed my rod, which was so hard and swollen that I feared the condom would burst, against the boundary of her entrance, which had closed up tight like a clam.

But whether it was because she was clenching so tightly or because of my lack of experience, it kept slipping out as I tried to push it in from above.

"Mmph... S-Sucha.

You're being mean," Chiuyu said, glaring at me with tear-filled eyes.

It seemed like she was panicking even more.

I took a deep breath and steeled my nerves.

I discarded the notion of gently guiding myself in while applying light pressure, refocusing instead on forcefully pushing my way inside.

Though a strange sense of guilt washed over me, if I didn't do this, we'd never be able to connect anytime soon.

Checking our position, I lined up against the slit and pried it open with the tip of the rod.

"Ah..."

Chiyu let out a sorrowful cry.

With a squelching sound, I confirmed that she had opened up to accommodate me, and I felt an indescribable surge of excitement at her softness.

"I-It's... It's fine, so just... keep going..."

"Ah...!"

Though impossibly narrow, the rod recognized it as a hole.

It was like carving a tunnel through a sandcastle.

As I advanced my hips inch by inch, I could feel Chiyu's vaginal walls being stretched wider.

Squelch, squelch, squelch... sluuurp...

Into Chiyu, who had never let anyone enter before in her life, I intruded halfway in one swift motion.

For an instant, I writhed in a bliss so intense it defied the boundaries of this world.

The sensation was immense both in my chest and inside her mouth, but describing it as incomparably pleasurable was still an understatement.

If I had to force a comparison...

It was warm enough that you’d gasp "Hot!" for a split second, like dipping into a hot spring.

Softer even than the fluffiest steamed bun.

With a grip far tighter than when I did it myself.

My cock was being sheathed in her.

"Mph... mph... All... of it... is it in?"

Looking at her, Chiyu had her fingers digging into the futon, her fist clenched tight, as a single tear rolled down her cheek.

Blood trickled from her intimate area, telling the story of her losing her virginity and the pain it entailed.

"Are... are you okay?"

"Is all of it in?"

To my childhood friend asking the same question again, I shook my head no.

"Just... a little more."

"Put it all in, quick."

Unable to refuse that absolute pressure, I thrust my hips the rest of the way forward.

The pleasure I had previously thought was the peak was updated as my entire cock was buried inside her.

"Ah, aah..."

"Mn... kuhh... Aaah...!"

Chiiru, who had accepted all of me, panted heavily, looking up at me with eyes that glistened.

"I-I... is this the end?"

"Yeah, it's all in."

"Mmm... so you lost your virginity."

"A-ah, yes."

"You lost yours with me too."

"Right.

It had to happen."

"Happy?"

"Very."

"Me too... but" Chiiru’s face twisted into a grimace.

"—This hurts way too much. 'First-Tier Healing'."

Chiiru cast a healing spell on her own crotch.

—I see, so it could be used like that.

Since it effectively amounted to a laceration, I supposed healing magic would work.

The pain seemed to fade quickly, and Chiiru’s expression softened.

"Shouldn't you have just used that right away?"

When I said that, Chiiru pursed her lips in a pout.

"I wanted to endure the pain and take all of you first... Is that so bad?"

I'd known it since we were kids, but my childhood friend was incredibly cute.

"It's not like I'm saying no. Thanks for trying so hard."

"Mm. Good to know you understand. Since I've healed it... feel free to move however you like."

Using a healing spell to overcome the taboo of thrusting deeply into a virgin was something unique to this desert island, or perhaps, more accurately, something that defined Senyuu's character.

But as a man, he couldn't think of anything more grateful for.

He could feel himself coming undone just from being inside her, yet his instincts were screaming at him to thrust. "Got it.

Here I come."

"Mm, here you come."

He pulled back slowly, then moved forward again.

It was just that simple motion, yet the pleasure threatened to shatter his very bones.

However, since this was a first-time act in an unfamiliar position, the initial back-and-forth movements didn't go smoothly.

Frustrating as it was, there is always a beginner's phase for everything.

Without any pretense or trying to save face, he moved his hips to find whatever rhythm he could manage given his inexperience.

"Mmm... ah... pfft... ah, ah... Because of you, my pussy is making those lewd noises."

With every slam of his hips against her, wet sounds—plish, plich—resounded through the air.

Chiya's moans, the vigorous swaying of her massive breasts, the obscene sounds of wet flesh slapping together, the impact of their hips colliding, the creaking of the bed frame.

All of it stirred his arousal to a fever pitch, merging with the overwhelming sensation inside her pussy to produce a pleasure that defied logic.

How long had he been ravaging Chiya from within?

It could have been tens of minutes, or perhaps just a few.

He and Chiya both threw sweat like beads onto the air, their bodies bouncing frantically on the bed.

Gradually, he got the hang of the rhythm, moving his hips with crisp, powerful thrusts—sometimes groping her breasts, other times linking their hands together as he drove into her.

"Sō... Sōkun... Sōkun...!"

He cherished his childhood friend calling out his name over and over, responding in kind by repeating "Chiya...!" each time she did.

And then, at last, the moment arrived.

"Ah... Sō-kun's is getting... swollen..."

"Chiya, I'm close...!"

As Chiya spread her arms wide, he caught her intent and shifted his position to reach out toward her.

His childhood friend wrapped her arms tightly around him, tangled her legs with his, and lunged to capture his lips.

「Hmm, chu, le-ro, e-ro, chu…… Sō-kun, cum, just do it, right there in the c*ck that just lost its childhood friend's virginity, spill your first ejaculation from losing your own virginity right now……”

Until the very last second, my childhood friend kept poking at our arousal.

No, knowing her, she’d probably say all sorts of things even in moments like this, just as she always does.

Feeling the press of her breasts against my chest, our lips overlapping, our bodies tangling around each other, I slammed my hips into her, catching the peak of pleasure without missing a beat and came.

“Chiyu……!”

In that instant, a bliss so intense it whitened out my brain took over, and white fluid spurted from the tip of my cock.

Seizing the moment, Chiyu pressed her lips to my ear, making lip-smacking sounds as she whispered into my eardrums.
###PAARA###
“Biuuuuuu~~, biu-ru-ru, biu-ru-ru, biu-biu. I’m biu-bi’ing inside my favorite childhood friend. Even though it’s my first time, I felt it deep inside Sō-kun. Keep going biu-biu till the end, it feels so good. After the squirts, keep milking me until even the thick stuff runs out.”

“Zip zip, zip-zip, zip zip, zip! Soaking it in the cock of my favorite childhood friend. Even though it’s our first time, I felt amazing right there, riding his huge dick all the way to the end, so good. After all that spurting, I milked every last drop until nothing but slime came out anymore.”

“...!”

Hit by a barrage of happiness, conquest, and satisfaction, my head was on the verge of breaking.

My hips shook wildly as I stayed pressed against her, enjoying every bit up to my ears until my pulse stopped.

As the wave of pleasure subsided, we met each other’s gaze and overlapped our lips.

I devoured her mouth somewhat roughly, but Chiyu responded by tangling her tongue with mine.

When we pulled apart, a strand of saliva connected our tongues.

Her face was melted beyond anything I had ever seen, her cheeks flushed with heat.

"Sō-kun, your rubber is really bulging inside." "Isn't it Chiyu's fault...?" "Maybe so. Let me see..."

I gently sat up and withdrew my shaft.

Unlike before we had begun, the shaft was slick and obscene, reflecting the light.

The tip swelled in a way I only ever saw in fiction.

"...I haven't even cast 'Vitality Enhancement,' but does that much come out?"

Chiyu's eyes were wide open.

"No, I didn't expect... actually, Chiyu."

"What?"

"Is it possible... that the 'Basic Healing' you cast immediately after I cum repeatedly is becoming a sort of training, just like casting 'Basic Healing' after 'Vitality Enhancement'?"

Whenever I grew tired or ejaculated, Chiyu would promptly cast her healing magic.

In other words, even when the white fluid was depleted, its regeneration began immediately.

On this desert island, the number of times we had repeated this cycle was already considerable.

As if my body had been slimmed down.

My stamina might have been forged in the raw, too.

"I see. Before long, you might become a sex maniac even without magic... Or are you already?"

"I'm definitely heading that way. What if I stay like this after returning to Earth?"

"...? Just do it every day."

Chie said it as if it were the most natural thing in the world.

While speaking, she pulled the condom off me and took my still-hard dick into her mouth.

"......!"

"Mm, chu, chu, lero lero, leee. Chu, mmm. It's clean now. So this is your kink too."

By the time Chie opened her mouth, my rod was back in a state of readiness. "Ch, Chie..." "I know. Before that..."

Chie put the condom in her mouth and turned the tip upside down.

"No way, Chie...!"

She swallowed all the retrograde cloudy fluid into her mouth, showed me with an "Nnh...tch," closed her lips, and swallowed it down in several gulps.

She had drunk it before, but I didn't think she would go that far even after I ejaculated inside the condom.

"Gulp... It's stiff as a board again. Put on the second one."

Chiyu tossed the empty, spent condom onto the floor with a casual flick.

There was a trash can in the room, but she probably figured it would turn me on more if I had to deal with it like this.

The traces of our lovemaking scattered across the room serve as excellent props, effectively conveying the atmosphere of the scene even within the fiction.

Chiyu, who knows my preferences so well, was willing to recreate even those specific details.

"Ahh... uh, are you physically okay?"

"I already healed it with magic, so I'm fine. Besides... I enjoyed it too."

Chiyu lay on her back again.

"You know, without any magic, how many times could you go?"

It was likely deliberate—the way Chiyu's words teased and provoked me.

I quickly moved to place the second condom within reach and began putting it on.

"I'll keep going until you hit your limit."

"…You've got a date."

Her entrance was still somewhat tight, but bearing down on the evidence of our recent intrusion, I thrust my hips forward once more.

"Ah..."

We overlapped our bodies as if time itself had ceased, exhausting our stamina to the point where we didn't even remember falling asleep, finally letting go of consciousness like passing out.

I thought to myself that I'd probably never fully understand the subtleties of a wisdom scene……

Finally, here comes the main event chapter.

"If you're thinking, 'Hurry up and show me an episode featuring another heroine' or 'Please keep feeding us more chest,'

I'd really appreciate your support."

It was a pale, almost skin-colored shade.

The part that swelled out like the cap of a baby bottle was where the semen was collected after ejaculation.

By putting it on the tip of the stick and skillfully rolling down the sheath, the condom would cover the stick. It was a condom.

Incidentally, there was no plastic, so there was no square packaging like in the dirty books.

It was a little disappointing, but since the contents could be generated, it was fine.

Since it was directly placed from the 'Inventory', there was no hygiene issue.

With trembling hands from excitement, he carefully put it on.

"...So, are you used to putting it on?"

A suspicious gaze flew from Senyuu, so he decided to clear up the misunderstanding by being honest.

"...I secretly practiced so I wouldn't fail when the time came with you."

"Practice? So you practiced with another girl?"

"No, it's... I practiced alone." His face flushed with shame.

Seeing my demeanor, Senyuu gave a small smile. "Sousuke, you're cute." "..."

"Don't worry. I've done a lot of mental exercises about losing my virginity, so I'm the same."

Saying that, Senyuu gently lifted the hem of her skirt. Her private parts were revealed.

Small, tightly closed, and smooth, that place had never allowed any intruder to enter, proving it to be a firm gate.

And now, reflecting the lantern's light was the sticky fluid dripping from the gate. My throat involuntarily made a gulping sound.

"...It's embarrassing when you stare too much."

"S-sorry. But, this is my first time seeing it up close..."

I had touched it many times before, but this was the first time I had seen it up close.

"Sousuke... don't tease me anymore." "O-okay."

I placed the hard rod, which I was afraid might burst the condom, against the boundary of the closed gate.

But, whether because it was closed too tightly or because of my lack of experience, it kept slipping up.

"nn... S-sousuke. You're mean." Senyuu glared at me with tear-filled eyes.

It seemed that I was being teased even more.

I took a deep breath and resolved myself.

I abandoned the idea of gently entering after positioning myself and instead decided to push in.

I felt a strange sense of guilt, but I knew that I wouldn't be able to connect otherwise.

I confirmed my position, aligned with her opening, and began to pry it open with the tip of the rod. "Ah..." Chiyu let out a pained sound.

When I confirmed that the gate had opened with a slight sound, I felt an incredible excitement at its softness.

"S, so-kun... It's okay, just keep going..." "Aa...!"

It was abnormally narrow, but the rod recognized it as a hole.

It was like digging a tunnel through a sandcastle.

As I pushed my hips forward little by little, I could feel Chiyu's vagina being stretched.

Nichi, nichi, nichi... Nuruun...

Halfway into Chiyu, who had never let anyone enter her before, I invaded her in one go.

For a moment, I writhed in a pleasure that seemed otherworldly.

While her breasts and mouth were already amazing, this was a comfort that defied comparison.

It was as warm as a hot spring, so much so that I couldn’t help but exclaim, “Hot!”

It was softer than a fluffy meat bun.

The grip was incomparably tighter than when I did it myself. The shaft was being enveloped.

“Huh… huh… huh… Did it all go in?”

Looking, Senyuu was scratching the futon with her nails, and tears were streaming from her eyes while she was gripping tightly.

Blood was dripping from her private parts, telling the story of her deflowering and the pain she was enduring. "A-are you okay?" "Did you put it all in?"

My childhood friend asked the same thing again, and I shook my head. "J-just a little more" "Put it in, faster"

Under her relentless pressure, I pushed my hips all the way in.

The pleasure I had thought was the best until now was renewed by the entire length of the shaft being buried inside her. "Ah, ah..."

"Nn... kuh... ah...!"

Chiyo, who had accepted everything about me, panted heavily and looked up at me with moist eyes. "Huh, huh... this time?" "Yeah, it's all in."

"Ah... I lost my virginity." "Ah, yeah."

"So you lost your virginity to me." "Yeah, I did." "Are you happy?" "I'm happy." "I am too... but" Chiyo's expression twisted.

"――This hurts too much. 'Basic Healing.'"

Chiyo cast a healing spell on her own private parts.

――Well, I see, there are uses for it like this.

Since it would be a wound if it were to tear, a healing spell should work.

The pain seemed to fade quickly, and Chiyo's face relaxed.

"Shouldn't you have used it right away?"

When I said that, Chiyo pouted as if she were sulking.

"Even if it hurt, I wanted to wait until I accepted you. Is that bad?"

I've known it since I was young, but my childhood friend is very cute.

「You did great. Thanks for trying.」

「Mm. That’s all right. I’m healed now… so you can move however you like.」

Using the ‘Healing Magic’ spell, overcoming the taboo of moving roughly with an innocent maiden is something unique to this desert island, or rather, something that’s typical of Senju.

But as a man, there was nothing more welcome than this.

It was so incredibly pleasurable just being inside that his instincts were begging him to thrust. "Got it. Then I'll go." "Mm, come."

He slowly pulled his hips back and then pushed forward again.

That was enough to make my hips feel like they were about to break from how good it felt.

But, considering this was my first time and in this position, I couldn't get the rhythm right at first.

It was frustrating, but there was always a beginner's phase to everything.

I didn't try to hide it, I just moved my hips awkwardly, trying to get the hang of it.

"Nn... Ah... Fuu... Ah, ah... Because of you, Sō-kun, my pussy is making dirty sounds."

Every time I thrust, the sound of pichu, patchu echoed.

A thousand moans, her huge breasts swinging wildly, the lewd squelching sounds, the thud of our hips colliding, the creaking of the bed.

All of it stirred excitement, and together with the feeling of her insides enveloping me, it produced an extraordinary pleasure.

How long had I been ravishing her?

It might have been several minutes or several hours.

Both she and I were drenched in bead-like sweat, jumping on the bed.

Gradually understanding how to move my hips, I would sometimes massage her breasts, sometimes hold her hands, and shake my hips vigorously.

"Sou-kun... Sou-kun, Sou-kun..."

My childhood friend called out my name over and over, and I responded, "Chiyu...!"

And then, finally, the moment arrived.

"Aa... Sou-kun's... swelling..." "Chiyu, it's almost time...!"

When she spread her arms wide, I sensed her intention and shifted my position to lean over her.

My childhood friend hugged me tightly, entwined her legs, and kissed me.

「Nn, chu, lelo, ero, chu... Sō-kun, cum, cum, just like that, lose your virginity inside your childhood friend’s pussy, and cum for the first time as a non-virgin...」

She continues to arouse me until the very end.

No, she’s probably going to say all this as usual, even now.

I feel her breasts against my chest, our lips touching, and our bodies intertwined as I thrust my hips, and when I reach the peak of pleasure, I cum.
「Senyuu...!」

Instantly, an overwhelming sense of bliss floods my brain, and white fluid spurts from the tip of my cock.

Senyuu immediately presses her lips to my ear and whispers while making lip smacking sounds.

「Buuuuuuh, buuru, buuru, bu-buuh buuuu. Cumming inside my favorite childhood friend’s pussy. Even though it’s your first time, you made me cum in my naughty childhood friend’s pussy, it feels so good. Cum until the last drop, until the gooey stuff stops coming out.」
「～～～～!」

The happiness, the sense of conquest, and the satisfaction overwhelmed me.

I shake my hips and let her pleasure me until my pulse stops.

Once the waves of pleasure subside, I meet her gaze and kiss her.

I kiss her roughly, but Senyuu wraps her tongue around mine in response.

When we pull away, our tongues are still connected by a string.

Her face was melting in a way I had never seen before, and her cheeks were flushed.

"Sou-kun, the condom is really swollen inside." "It's probably because of Senyuu..." "Maybe. Can I see...?"

I gently sat up and pulled the stick out.

Unlike before, it was slick and reflected the light in a lewd manner.

The tip was swollen in a way I had only seen in fiction.

"...Even without 'Vitality Enhancement,' does it come out like this?" Senyuu's eyes were wide open.

"No, I didn't expect it to come out like this... Anyway, Senyuu." "What?"

"Maybe... right after you overcame 'Basic Healing,' it's like the 'Basic Healing' after 'Muscle Enhancement'... Isn't it like training?"

Whenever I got tired or ejaculated, Senyuu would immediately cast healing magic on me.

In other words, even if the white fluid ran out, it would start regenerating right away.

The number of times we repeated this on this desert island was already quite significant.

My body had slimmed down accordingly.

Maybe my stamina had actually been trained, too.

"Interesting. You might become a perpetual stud even without magic... or are you already?"

"You're getting there. What are you going to do if it stays like this when we get back to Earth?"

"...? Just do it every day."

Chiyu said it as if it were no big deal.

As she spoke, she removed the condom from me and took the still-hard shaft into her mouth. "...! "

"nn, chuu, chuu, lelo, leeeeee. chuu, nn. It's clean now. This is also part of your sexual preference."

By the time she let go of it, the shaft was back in fighting form. "Ch-Chiyu..." "I know. Before that..."

Chiyu put the condom in her mouth and turned it upside down. "Chiyu, you can't be serious...!"

She swallowed all the white fluid that had flowed back into her mouth, showing me with a "nha..." before closing her lips and gulping it down several times.

She had done this before, but to drink everything even after the condom, that was something else.

"Kep... It's getting hard again. Put on the second one."

Chiyu tosses the empty condom onto the floor.

There's a trash can, but she probably thought that throwing it on the floor would get me more excited.

The traces of our activities scattered around the room can be good props to convey the atmosphere, even in fiction.

Chiyu, who knows my preferences, is trying to recreate even these details.

"Ah, um, are you okay?"

"I'm fine, I healed myself with magic. And... I enjoyed it too." Chiyu lies back down.

"So, without magic, how many times can you do it?"

Probably on purpose, Chiyu's words are meant to tease me.

I quickly put another contraceptive in place and put it on.

"I'll stay with you until you reach your limit." "......I accept."

Even though it's still a bit closed, I press the stick against the split that still bears the marks of the intrusion and thrust into her again. "Ah..."

We piled our bodies on each other as if it would never end, exhausting our energy to the point where we didn't even know when we fell asleep, and ended up losing consciousness.

I'll never understand the wisdom scene... I thought, but

it's finally the main event.

If you thought, "Show us the other heroines' scenes" or "Please continue with the breasts," please support me.
