It was a thin, pale flesh-colored material.

The tip was bulbous, like the cap of a baby bottle, designed to collect the semen after ejaculation.

The mechanism was simple: place it against the tip of the rod and skillfully roll the sheath down, allowing the contraceptive to cover the length of it.

In other words, a condom.

Since plastic didn't exist here, it lacked the square foil packaging often seen in adult books. While a small part of me found that slightly disappointing, the fact that I could generate the actual item was what mattered. Since it was a direct placement from my Inventory, there were no hygiene concerns either.

With my hands trembling from excitement, I began to put it on securely.

"...So-kun, are you used to putting those on?"

Chiyu shot me a suspicious look. To clear up any misunderstanding, I decided to be honest.

"...I practiced in secret so I wouldn't mess it up when I did it with you."

"Practiced? Was the punchline that you used another girl as a partner?"

"Of course not. It was... by myself."

My face burned with embarrassment. Seeing my reaction, the corners of Chiyu’s mouth curled into a tiny, subtle smile.

"So-kun, you're cute."

"..."

"It’s okay. I’ve done plenty of mental training for losing my virginity too, so we're even."

As she spoke, Chiyu gently lifted ❖ Nоvеl𝚒ght ❖ (Exclusive on Nоvеl𝚒ght) the hem of her skirt.

Her private area was laid bare. Small, tightly closed, and smooth—it stood as proof of a fortress that had never permitted a single intruder to pass its gates.

And now, reflecting the light of the lantern, was the viscous moisture dripping from those gates. I felt my throat go dry as I gulped involuntarily.

"...It’s embarrassing when you stare that much."

"S-sorry. But it’s the first time I’ve actually... looked closely."

I had touched her many times before, but this was the first time I was seeing it from such a short distance.

"So-kun... don’t tease me anymore."

"O-okay."

I brought the rod—so engorged I worried the condom might burst—to the boundary of her private area, which was pressed together like a closed shell.

However, whether it was because she was so tightly closed or simply due to my lack of experience, the tip kept sliding upward when I tried to enter.

"Ngh... S-So-kun. You're mean."

Chiyu glared at me with teary eyes. It seemed she thought I was teasing her further on purpose.

I took a deep breath and steeled my resolve. I abandoned the idea of a light, sliding entry and reframed it in my mind: I had to push my way inside.

I felt a strange pang of guilt, but if I stayed like this, we would never be joined.

I confirmed the position, pressed against the crease, and used the tip of the rod to pry the way open.

"Ah...!"

Chiyu let out a pained, yearning cry.

Schlick... As I felt the gates open, the sensation of her softness sent a surge of incredible excitement through me.

"S-So-kun... it’s okay, just... keep going..."

"Aah...!"

It was extraordinarily narrow, but my body recognized it as a path. It felt like carving a tunnel into a sandcastle. As I slowly pushed my hips forward, I could feel Chiyu’s interior being forced open and expanded.

Squish, squish, squish... slip.

I surged halfway inside her, entering a place where no one else in her life had ever trodden. In that instant, I writhed from a pleasure that felt otherworldly.

Her breasts and mouth had been incredible, but this was a comfort beyond comparison. If I had to force an analogy...

It was warm enough to startle me for a second, like a hot spring. It was softer than the fluffiest steamed bun. And the tightness was incomparable to anything I could do with my own hand.

My rod was being completely enveloped.

"Haa... haa... haa... is it... all the way in?"

Looking down, I saw Chiyu gripping the mattress so hard her nails dug in, a single tear escaping her eye. A small amount of red was dripping from her private area, telling the story of her deflowering and the pain that came with it.

"A-are you okay?"

"Is it all the way in?"

When my childhood friend asked the same thing again, I shook my head.

"A-a little more."

"Put it in. Hurry."

Driven by her undeniable pressure, I pushed my hips forward until I reached the end. The pleasure I had thought was peak just moments ago was instantly overwritten as the entire rod was buried within her.

"A-aah..."

"Ngh... kuuh... ahh...!"

Having accepted all of me, Chiyu let out a ragged breath and looked up at me with moist eyes.

"Haa, haa... how about now?"

"Yeah. It’s all the way in."

"Mhm... I lost my virginity to So-kun."

"Y-yeah."

"And So-kun lost his to me."

"That’s how it works out."

"Are you happy?"

"I'm blissful."

"Me too... but..."

Chiyu’s expression flickered with a wince.

"—This hurts too much. Basic Heal."

Chiyu cast Healing Magic on her own private area.

—I see. So it can be used like that.

Strictly speaking, it was a laceration, so healing magic would naturally be effective. The pain seemed to recede instantly, and Chiyu’s face softened.

"Shouldn't you have used that immediately?"

When I asked, Chiyu puffed out her cheeks in a pout.

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

I’d known it for a long time, but my childhood friend was incredibly cute.

"It’s not bad. Thank you for working so hard for me."

"Mhm. As long as you understand. It’s healed now... so you can move however you like."

Overcoming the taboo of moving vigorously with a virgin partner by using Healing Magic was either a uniquely deserted island solution or just very "Chiyu."

But as a man, there was nothing more appreciated. Just being inside was enough to make me feel like I was going to finish, but my instincts were screaming at my hips to start moving.

"Alright. Here I go."

"Mhm. Come."

I pulled my hips back slowly and then pushed forward again. That simple motion alone was so pleasurable I felt like my waist was going to give out.

However, since this was my first time and a new physical sensation, my movements were clumsy at first. It was frustrating, but everyone starts as a beginner. I didn't try to fake it; I just kept moving my hips, trying to find the rhythm despite my lack of skill.

"Ngh... ah... fuuh... ah, ah... Because of So-kun, my p*ssy is making such lewd sounds."

With every strike of my hips, a wet splat and squelch echoed through the room.

Chiyu’s pants, her magnificently swaying large breasts, the lewd water sounds, the thud of our hips meeting, and the creaking of the bed—all of it fanned my excitement, merging with the sensation of her interior to create an extraordinary level of pleasure.

How long had I been devouring her? It could have been dozens of minutes, or just a few.

Both Chiyu and I were bouncing on the bed, sweat flying like pearls from our bodies. I eventually began to grasp how to move my hips, sometimes kneading her breasts and sometimes interlacing our fingers as I swung my waist rhythmically.

"So-kun... So-kun, So-kun...!"

My childhood friend, repeatedly calling my name, was so precious to me that I answered back, "Chiyu...!" over and over.

Finally, the moment arrived.

"Ah... So-kun’s... it’s pulsing..."

"Chiyu, I'm...!"

Chiyu spread her arms wide. Catching her intent, I shifted my position to lean over her completely. My childhood friend hugged me tight, entwining her legs with mine, and lunged for my lips.

"Mmm... chuu... nh... slurp... So-kun, let it out, let it out... right there, into your childhood friend’s freshly deflowered p*ssy... have your first ejaculation from graduating your virginity..."

She was fanning my excitement until the very last second. 𝐟𝚛𝕖𝚎𝕨𝗲𝐛𝚗𝐨𝐯𝐞𝕝.𝐜𝗼𝗺

But knowing her, even at a time like this, she would probably say that as usual.

Feeling the sensation of her breasts against my chest, our overlapping lips, and our entire bodies entwined, I struck with my hips and released, not missing the moment the pleasure reached its zenith.

"Chiyu...!"

In that instant, a sense of euphoria that turned my mind blank dominated my brain, and the white fluid burst forth from the tip of the rod.

Chiyu immediately pressed her lips to my ear, whispering against my eardrum with a wet sound.

"Spew~~~~~, gush, gush, squirt~~~~~. Pumping it all into your favorite childhood friend. Even though it’s my first time, I felt so much inside my lewd childhood friend p*ssy... it feels so good to have it all burst inside. Keep pushing it out until the very last drop."

"~~~~~!"

The combined assault of euphoria, conquest, and satisfaction almost made my head spin. My hips twitched as I clung to her until the last pulse subsided, my ears ringing with happiness.

As the waves of pleasure calmed, our eyes met and our lips overlapped. I devoured her lips somewhat roughly, and Chiyu responded by tangling her tongue with mine.

When we pulled away, a thread of saliva connected our tongues. Her face was more melted than I had ever seen it, and her cheeks were flushed deep red.

"So-kun, the rubber is so swollen inside."

"That’s your fault..."

"Maybe. Show me...?"

I slowly pushed my upper body up and withdrew the rod. Unlike before we started, it now reflected the light with a slick, lewd sheen. The tip was swollen in a way I had only ever seen in fiction.

"...I didn't cast Energy Up, but can that much really come out?"

Chiyu’s eyes were wide.

"I didn't think that much would come out either... wait, Chiyu."

"What?"

"Is it possible... that using Basic Heal right after I finish is... just like using it after Strength Up? Is it like training?"

Whenever I got tired or finished, Chiyu would immediately cast healing magic on me. In other words, even if my supply was depleted, reproduction began instantly. On this deserted island, the number of times we had repeated that was already considerable.

Just as my body had trimmed down... my stamina and potency might have been trained naturally as well.

"I see. Eventually, you might become an insatiable So-kun even without magic. ...Wait, are you already?"

"I'm getting there. What am I supposed to do if it stays like this when we go back to Earth?"

"...? We’ll just do it every day."

Chiyu spoke as if it were the most natural thing in the world. As she spoke, she removed the rubber from me and took the still-hard rod into her mouth.

"...!"

"Mgh... chuu... lick, slurp... chuu, mhm. All clean. So-kun likes this too."

By the time Chiyu pulled away, the rod was back in its combat-ready state.

"Ch-Chiyu..."

"I know. But before that..."

Chiyu took the rubber into her mouth and tipped the end upside down.

"No way, Chiyu...!"

She caught all of the backflowing white fluid in her mouth, showing it to me with a "Nnh..." before closing her lips and swallowing it in several gulps. She had swallowed for me before, but to do it even after I’d finished in a condom...

"Burp... It’s rock hard again. Put on the second one."

Chiyu tossed the emptied, used condom onto the floor. There was a trash can, but she likely thought this would excite me more. The traces of the act scattered around the room were good props for conveying the atmosphere, just like in fiction. Knowing my tastes, Chiyu was recreating even those details.

"Y-yeah. Is, uh, your body okay?"

"I already fixed it with magic, so I'm fine. Besides... it felt good for me, too."

Chiyu lay back down on her back.

"So-kun, without magic, how many times can you go?"

Her words were provocative, almost certainly on purpose. I immediately generated a second contraceptive and began putting it on.

"I'll stay with you until you hit your limit."

"...Challenge accepted."

I brought the rod to the crease—still somewhat closed but bearing the strong marks of an intruder—and thrust my hips inside once more.

"Ah...!"

We continued to join our bodies as if the night would last forever, exhausting our strength until we couldn't remember when we finally fell asleep, losing consciousness as if we had blacked out.
