Parameter Supremacy: The Man Who Seizes a Harem Through Sheer Effort.

Moe’s First Time.

My rundown apartment had no proper changing area.

The moment you stepped up from the entrance, the entire place lay open before you. No matter where anyone stood, they could see everyone else.

It was decided that Moe would undress first in front of the living room and head to the bathroom.

I turned my back to her and closed my eyes. Even though I knew I would eventually see her naked body, it still felt far too stimulating for me right now. There was a very real chance I would react whether I wanted to or not.

Chance? No… it was a certainty.

Taking a shower together with Moe in this state would be utterly pathetic. It would be far wiser to simply meditate.

That was what I told myself as I kept my eyes shut, yet every rustle of fabric as Moe removed her clothes instantly dyed my mind—which should have been pure white—into a vivid shade of pink.

The slightly heavy sound of denim pants hitting the floor. Then the soft flutter of lighter clothing falling after it.

Light clothing… Ah…

After a while, Moe’s light voice called out, “Okay~ You can look now.”

Somehow, she seemed far more composed than I was.

I opened my eyes and turned around. At the edge of the room lay Moe’s clothes, folded somewhat haphazardly. She had apparently tried to hide her underwear, but a glimpse of white lace still peeked out from beneath the neatly folded denim pants.

Gulp.

Swallowing hard, I began undressing as well. There was no point in describing my own disrobing. I quickly stripped everything off and, after a moment of resolve, knocked on the bathroom door—the gateway to this untouched frontier.

“I’m coming in.”

“Okay~”

After hearing Moe’s reply, I gave up trying to hide the insistent bulge at my crotch and opened the bathroom door.

***

Moe was standing there, completely naked, under the shower.

It should have been the most natural sight in the world, yet when I thought about our relationship up until now, it felt strangely unreal—like I was seeing something I wasn’t supposed to see. A deeply immoral, forbidden scene.

Water poured over her head, tracing the generous curves of her breasts before dripping from their tips onto the floor. Even when I tried to look away, my gaze was drawn back. They were large, soft-looking, and glistening with seductive sheen.

They proudly proclaimed her femininity.

In contrast, her relatively small, adorable areolas only heightened the lewdness.

She really is different from Midori.

Such an insolent thought flickered through my mind for the briefest instant.

This was bad. My body was already beginning to show an embarrassingly honest reaction.

Moe glanced at me as I entered the bathroom, then shyly covered her chest and lower abdomen with her hands. Yet she couldn’t fully hide her generous backside, which radiated an oddly raw sensuality.

“Ahaha… It’s still embarrassing when you actually look, huh?”

Her voice was gentle. There wasn’t even a hint of reproach.

“I’m embarrassed too, you know. Come on, let’s wash our hair and bodies first.”

I handed her the shampoo that had been left on the floor. Both the shampoo and body wash had been chosen by Shiina. They suited a woman’s skin perfectly.

“Ah! It smells just like Shii-chan.”

…Of course she’d notice.

“…”

“Fufu, did Shii-chan pick this out?”

“…Yes.”

“Fufu.”

Moe let out a small laugh and crouched down to wash her hair, as if trying to hide her embarrassment.

From above, her defenseless back, wet limbs, and the movement of her shoulder blades came into view. Once again, wicked feelings stirred deep in my chest.

I let out a deep breath and picked up the shampoo to wash my own hair.

After rinsing off the foam and opening my eyes, I looked down to find Moe staring intently at my crotch.

“…Don’t stare so much.”

“Ufufu. But it’s so obvious.”

“It’s a physiological reaction. Can’t be helped.”

“Are you getting excited because of me?”

“…”

“I see…”

The conversation broke off, leaving only the sound of the shower filling the bathroom. Moe slowly raised her gaze and gave me a soft smile.

“This… is because of me, right?”

“Well… yeah, you could say that.”

“Fufu. Then let me help make you feel better.”

With those words, Moe picked up the body wash, slowly lathered it between her palms, and then wrapped her soapy hands around my groin.

Up and down. Softly.

Anything beyond this would be far too obscene. I’ll leave the rest to your imagination, as usual.

In any case, it was quite… no, an extremely embarrassing experience for me.

***

Without even putting on underwear and with our hair still damp and only roughly towel-dried, we didn’t bother laying out the futon. I pressed Moe down onto the tatami with a heat intense enough to make me forget its coldness.

“Moe…”

“Ryuuji-kun… Mm.”

Moe closed her eyes and tilted her chin up slightly, as if begging for something. I desperately held back my raging desire and placed a gentle, feather-light kiss on her lips.

“Mmm… Haah… My first kiss.”

“I see. I’m glad.”

I wasn’t particularly obsessed with virginity, but the feeling of stepping onto fresh snow still made my heart flutter. With a small sigh of relief, I continued raining soft kisses down on her.

“Mmm… Ah… Ryuuji… kun…”

Every time our lips parted, Moe’s sweet breath coiled around me. Gradually the kisses grew deeper, and even the heated breaths and saliva spilling from our mouths turned into an intoxicating scent that fueled our desire. Reason faded away, leaving only raw need.

When I glanced down, the tips of her breasts had stiffened noticeably, proudly asserting themselves. I pinched one gently between my fingers and rolled it slowly, teasing her.

“Nn… Ahh… Ah… Ahh!”

Moe’s voice jumped up in an instant. Her reaction spoke louder than any words. It seemed her weakness was concentrated right at the center of those generous breasts. The match was merciless. An exposed weakness was destined to be toyed with without mercy.

Every time I kneaded her breasts, pressed them with my palms, and persistently rolled her nipples with my thumbs, her body gave a small, adorable jolt.

“Ah… Nn… Ahh…”

Her sweetly melting voice, which stirred protective instincts, continued to echo through the small room.

***

I slowly pulled my mouth away from the nipple I had been sucking.

“Ah…”

A voice laced with lingering regret spilled from Moe’s throat.

I sat up, lifted her thighs, and raised them slightly.

“Ah… Yaa…”

Overwhelmed by shame, Moe let out a cry and hurriedly covered her crotch with both hands.

“…Do you hate it?”

When I asked, her face flushed bright red as she slowly shook her head from side to side.

I gently touched her hands and applied a little pressure. As if losing the will to resist, she resigned herself and moved her hands away.

The place she had never shown or let anyone touch in her entire life—I brought my lips to it without hesitation.

“Ah… Wait… Nn…”

Her pleading voice came too late. I slid my tongue along her secret place.

Instantly, Moe’s body jerked violently, and her sweet, tormented moans grew louder.

“Nn… Nn… Ah, Ryuuji-kun… Ah… Ahn…”

Then I placed a deliberate kiss on the spot that was likely the most sensitive part of a woman.

“Nn~~~~… Ah… Ahn… Ah, yaa…”

After relentlessly tormenting her with my tongue and fingers, she suddenly arched her back and released a powerful spray of pleasure.

Moe had climaxed surprisingly easily from her very first foreplay.

***

Still holding her small body in my arms, I kissed her again and again. Moe responded in kind, wrapping her arms around my neck and desperately seeking my lips in return.

I pressed my chest against her breasts as I loomed over her. Just that contact sent a shiver of pleasure through me.

“Haah… Haah… Moe, I’m going to put it in.”

“Haah… Yeah… Take my first time.”

Even as she said, “It feels wrong to use the same things you and Shii-chan use,” Moe handed me the condom she had brought with her.

“Hey, Ryuuji-kun.”

“What?”

“Can I… try putting it on you?”

“Hm? Sure, go ahead.”

Moe carefully opened the package and positioned the condom at my groin.

“Is this side up…? Huh…? Uu… It’s so big…”

Seeing her struggle, I gently placed my hand over hers.

“Here, now just roll it down.”

“Waa… This is interesting… It’s so tight…”

Even in the middle of such an act, the innocent expression she showed for a moment created an irresistible gap that inflamed me even more.

Unable to hold back any longer, I gently pushed Moe down.

“…I’m putting it in.”

“Yeah… Please…”

I aligned myself with her narrow entrance and slowly pushed inside.

“Ugh…”

For a brief moment, a voice holding back pain escaped her, but surprisingly, there was almost no resistance. She accepted me smoothly.

I stayed still for a moment, then gradually applied pressure deeper and deeper into her.

“Nn… Ah… Maybe I can’t… Ryuuji-kun… That feels… way too good…”

Tears welled in her eyes as she pleaded, but there was no turning back now.

Savoring the sensation inside her, I began to move my hips slowly.

***

“U~… I’m so happy…”

Lying naked in my arms, Moe murmured with a completely relaxed expression. Her face was so peaceful it was hard to believe the heat from earlier had even existed.

“…Did it hurt?”

“Nope. It felt really, really good. I heard the first time is painful, so I was a little scared… but it wasn’t like that at all.”

Moe spoke with a fluffy, blissful look on her face, as if tiny flowers were blooming around her.

For her first time, she seemed surprisingly sensitive. Probably because she was usually… No, that would be tactless.

Still, we had taken things quite leisurely. When I checked the clock, the night had already grown very late.

Midori might start worrying soon. With a touch of reluctance, I swallowed that lingering feeling and spoke to Moe.

“Moe. It’s getting really late… I’ll walk you home.”

“Eh?”

“…What’s wrong?”

Moe smoothly slipped out of my arm pillow and walked over to her luggage completely naked, her steps light and bouncy.

Her swaying, generous bottom looked strangely defenseless… Honestly, it was incredibly erotic.

“Actually, I was planning to stay over tonight, you know?”
