While Taking Care of My Shut-In Little Sister, I Somehow Ended Up Ejaculating Inside a Beautiful Girl - Chapter 71: At the End of the First Day of Confinement

Chapter 71: At the End of the First Day of Confinement

“Nnngh~~~♥♥♥♥”

Yuu, facing the bathroom door with her hands pressed against it, her hips turned toward me, let out a strained, muffled moan.

In the so-called standing doggy position.

She’d already been pounded from behind multiple times, barely able to muster the energy for her cries of pleasure, her hips trembling, her exposed lower body and the back muscles under her shirt quivering.

Twitch-twitch, twitch-twitch.

Her whole body shuddered.

Again and again.

Multiple times.

“Re…n…♥♥♥♥ Re…n-cha…♥♥♥♥”

Calling my name lovingly, repeatedly, she clamped down on my penis so tightly it hurt.

Her vagina felt so tight it almost seemed narrower than before.

The intense pressure tried to push my penis out, yet simultaneously invited it in, welcoming it.

The writhing, worm-like movements inside her vagina pushed me out while pulling me in.

—But.

“—Kuh! Yuu!”

My penis didn’t stay put. Feeling her vaginal movements, I thrust my hips forward.

My penis, invading with wet nyuchi-nyuchi sounds, forcibly spread her vaginal walls with its glans.

“Ren-cha!♥♥♥♥—Agh!♥♥♥♥ Aaaaaaah!♥♥♥♥”

Her moans, like screams, filled the air as I thrust my penis deep inside, stopping just short of her cervix.

“—Ngh!?♥♥♥♥”

The flared glans, its wide umbrella, scraped and gouged her vaginal walls as I pulled back, making her cry out again, her voice a mix of scream and moan.

“Nnnghaaaa!♥♥♥♥”

This was already her umpteenth thrust. Each time I drove in or pulled out, she let out a throaty moan mixed with wet sounds, her vagina writhing intensely, her body trembling violently.

She’d already climaxed multiple times.

Her moans were nearly screams, yet she didn’t ask to stop.

Far from it—

“Ren…cha…♥♥♥♥ Re, n-cha, ngh!♥♥♥♥”

With snot dripping from her nose, a trickle of drool from her mouth, and glistening tears in her eyes, she desperately screamed my name.

Drenched in bodily fluids, she wore a blissful, happy expression.

“Ren…chan…!♥♥♥♥ Mo…re!♥♥♥♥”

“Yuu—!”

Her trembling legs and hips shook uncontrollably.

Still pressing her hands against the bathroom door, hips thrust out, barely able to stand.

It looked nearly impossible to continue, yet she shook her long, glossy black hair, arched her back like a shrimp, and roared my name with all her might, demanding more.

“Ren…chan!♥♥♥♥ Re…!♥♥♥♥ Ren…chan!♥♥♥♥ Make… me…♥♥♥♥ Mess… me… up!♥♥♥♥ Ooh!♥♥♥♥ Ohhh!♥♥♥♥ Drive… me… crazy~~~!♥♥♥♥”

“…Kuh! Yuu! Yuu!”

Fiercely, lewdly, vulgarly—yet bravely.

She screamed, her legs trembling wildly.

“Ren…chan!♥♥♥♥ Ren…chan!♥♥♥♥ Ren…chan!♥♥♥♥ Ren…chan!♥♥♥♥ Ren…chan!♥♥♥♥ Ren…chan!♥♥♥♥ Ren…chan!♥♥♥♥”

“Yuu! I’m… coming! I’m gonna cum! I’m gonna cum now! I’m coming—!”

“Come!♥♥♥♥ Cum!♥♥♥♥ Deep… inside!♥♥♥♥ In… my… pussy!♥♥♥♥ Deep!♥♥♥♥ Womb!♥♥♥♥ Deepest… part!♥♥♥♥ Cum… inside!♥♥♥♥”

“I’m—coming—!!”

Her vagina, clamping painfully tight, seemed to signal her climax.

It felt like our timings—my ejaculation and her climax—synced in a strange, mystical way.

As if our hearts and bodies became one, I surrendered to the overwhelming pleasure, pressing my penis against her deepest point—her cervix.

“I’m—cumming—!!”

I thrust my penis in, ejaculating fully.

“—Ooooh!♥♥♥♥♥”

Hearing her hoarse, near-fainting scream as I hit her cervix.

Without hesitation, I pressed the tip of my still-ejaculating penis, or even the entire glans, into her cervix, like a deep kiss.

I ground the tip hard against her deepest point, continuing to release.

“Nnnoooohhh!♥♥♥♥♥”

Shaking her long black hair, arching her back sharply, she looked upward.

Her mouth opened and closed like a fish gasping for air, her legs trembling like a newborn fawn, her body convulsing violently.

Her hoarse screams came in broken bursts.

“…Ngh!♥♥♥♥♥ Nnngh!♥♥♥♥♥ Nnoh!♥♥♥♥♥ Ohhh!♥♥♥♥♥ …Oh!♥♥♥♥♥ …Ho…♥♥♥♥♥ Ohaaa!♥♥♥♥♥ …Ha!♥♥♥♥♥ …Aaa!♥♥♥♥♥”

As I kept grinding the tip of my penis against her cervix.

Her convulsions and hoarse screams—her climax reactions—didn’t stop.

“…Yuu. I love you.”

“Ren!?♥♥♥♥♥ Nn…cha!♥♥♥♥♥ I…♥♥♥♥♥ Love…♥♥♥♥♥ You…!♥♥♥♥♥ Ren!♥♥♥♥♥ Ncha!♥♥♥♥♥ Ren…cha!♥♥♥♥♥—”

Her screams had dropped several levels in volume.

She was at her limit, her energy now focused solely on staying conscious.

…Guess it’s about time to stop.

Normally—no, normally, I’d pull back here.

But.

She wouldn’t be satisfied with that.

What she seeks can’t be fulfilled like that.

She loves me.

And she says she wants more of my love.

What counts as love is debatable.

…But.

The love she seeks isn’t something vague like “normal” or “moderate.”

—What she seeks.

What she truly desires.

Is proof of being “more” mine.

I don’t know exactly what that is.

But I know it’s not “hesitation” or “restraint.”

I know she wants to fully accept me.

—So.

“Yuu. I love you.”

“Ren…cha!♥♥♥♥♥ I…♥♥♥♥♥ Love…♥♥♥♥♥ Love…♥♥♥♥♥ Love you…!♥♥♥♥♥”

…I thrust the tip of my penis, pressed against her cervix, into it again.

“—Nnoooohhh!?♥♥♥♥♥”

…I thrust into her cervix again.

“—Ngh!♥♥♥♥♥ Nnnoooohhhhh!♥♥♥♥♥”

And when she started to catch her breath.

“—Nngh!♥♥♥♥♥ …Ha!♥♥♥♥♥ Ha…♥♥♥♥♥ Ha…♥♥♥♥♥”

I thrust into her cervix again.

“Nnoooohhh!♥♥♥♥♥”

…I repeated this several times.

And, as expected.

After several thrusts into her cervix, her limbs went limp.

“—Nnah!♥♥♥♥♥”

“Whoa!”

With a chupon, my penis was pushed out, her open vagina leaking semen.

Her hips buckled.

“Yuu—”

Having been skin-to-skin, I sensed it coming.

I caught her body, hugging her as we sank in front of the bathroom door.

“…♥♥♥♥♥”

Breathing heavily—ha, ha—she leaned her back against my chest, completely limp.

“…Yuu. You okay?”

“Ren…chan…♥♥♥♥♥”

She turned to me with a weak but blissful smile.

Her light blue shirt, soaked with sweat, clung to her skin, outlining her black bra.

“You… thrust so much…♥♥♥♥♥ Came… so much inside…♥♥♥♥♥ Thank… you…♥♥♥♥♥”

“Yuu. Thank you. It felt amazing.”

“Me… too…♥♥♥♥♥ The… best…♥♥♥♥♥”

“Yuu?”

“…♥♥♥♥♥ …Suu… suu… suu…”

“She’s asleep.”

No wonder, after all that.

Her vagina, lower abdomen—her whole body—convulsed so much.

She must’ve pushed herself too hard, falling asleep in my arms.

…At the edge of my vision, semen dripped from her exposed lower body, her vagina.

“So erotic…”

Oops, my penis got hard again.

“…Be quiet for now, my son.”

I scolded my rebellious penis, trying to rise against her back.

“Yuu. I love you.”

I fixed her hair tangled at her neck and kissed her nape.

*

Of course, today—me and Yuu—didn’t stop at one round.

For example, in the kitchen.

“Nooo!♥♥♥♥♥ I’m cooking!♥♥♥♥♥ Noo!♥♥♥♥♥ Not—deep!?♥♥♥♥♥ Don’t thrust so deep!♥♥♥♥♥ I’ll spill it~~~!♥♥♥♥♥”

In the dining room.

“No!♥♥♥♥♥ The table’ll get dirty!♥♥♥♥♥ The food!♥♥♥♥♥ It’ll get cold~~~!♥♥♥♥♥”

In the bathroom.

“I’m Ren-chan’s personal flesh toilet!♥♥♥♥♥ Fill me!♥♥♥♥♥ More!♥♥♥♥♥ Cum!♥♥♥♥♥ Pour it in my pussy!♥♥♥♥♥”

In the bath.

“My voice!♥♥♥♥♥ Echoes!♥♥♥♥♥ Ren-chan!♥♥♥♥♥ Talk more!♥♥♥♥♥ Bite my ear!♥♥♥♥♥ Like ‘nom’!♥♥♥♥♥”

We indulged in intense, almost exhaustive “normal” (if you can call it that) hardcore sex all over the Onodera household.

I didn’t keep count, but I ejaculated a fair number of times, careful not to push Yuu to the point of fainting by avoiding her cervix—though I slipped up a few times, triggering her overwhelming climaxes, which was quite something. Overall, I think we managed to keep things relatively peaceful while intertwining our bodies.

Starting in the morning with confinement and ending with relentless, pounding sex, it was a truly wild day.

…A holiday this decadent must be rare.

And then, night.

Yuu and I lay naked on her bed, ready to end the day.

Her vagina still oozed the semen I’d released throughout the day, requiring constant tissue changes under her hips.

“Should we take another bath…?”

“No way!♥♥♥ I wanna sleep with Ren-chan like this!♥♥♥”

“Got it. Then we’ll sleep as is.”

She wouldn’t listen anyway, so I surrendered to the pleasant exhaustion and emptiness.

She’s still naked, with semen lingering inside her. Sleeping like this might dirty her bed… but oh well, too late now.

“Nfufu!♥♥♥”

Clinging tightly to my arm, she snuggled close, giggling happily and rubbing her cheek against my shoulder.

Our naked closeness, under the covers, let us feel each other’s warmth intensely.

Yet, it wasn’t uncomfortable, and I felt a strange calm, hoping for a good night’s sleep.

“Gonna sleep well tonight?♥♥♥”

“…Yeah, thanks to you.”

“Nfufufu!♥♥♥”

Her whispering giggles were oddly soothing.

As I relaxed, my mind calmly began reviewing the day. My body was already preparing for sleep.

“Sorry about today. I could’ve been gentler…”

“Nuh-uh!♥♥♥ It’s fine!♥♥♥ I’m happy with anything Ren-chan does!♥♥♥ I’m thrilled you got that excited for me!♥♥♥”

“I see.”

…Surprisingly, though.

I gave in to my surging sexual urges, and while I worried I might’ve been too rough, Yuu seemed overjoyed about it.

It was, apparently, a highly successful day.

…Not that surprising, maybe.

She clearly rejected restraint today.

She wanted something more intense, more direct than ever.

All we did was… well, do it. Non-stop from afternoon onward.

I gave in to my lust and ravished her.

Could that really answer her feelings? No, the meaning or significance isn’t the point.

Did I truly respond to her feelings?

“Ren-chan…♥♥♥ I wanna make days like today a regular thing!♥♥♥”

“A day to tie up your lover?”

“Oh, come on!♥♥♥ I said sorry!♥♥♥ I did it because I trust you—!”

“It’s fine, I get it.”

We teased each other, but there seemed to be a deeper reason behind her using “confinement” to make me ejaculate.

—She said:

“I believed in your nature, Ren-chan!♥♥♥”

My nature—something about “acting when pushed” or whatever.

“My nature, huh? Even I didn’t know about that.”

“Of course!♥♥♥ It’s your survival instincts or your primal male habits!♥♥♥”

“…”

Wow. I was a bit speechless, stunned by how deeply Yuu had analyzed me as a “male.”

“…You know me that well?”

“Of course!♥♥♥ It’s you, Ren-chan!♥♥♥”

“…”

I felt genuine awe, even respect, for her insight, but the conversation veered into lovey-dovey territory, leaving me flustered.

“Nfu!♥♥♥ You’re blushing!♥♥♥ So cute!♥♥♥”

“Hey now.”

“But you understand me deeply too, don’t you?♥♥♥ We’re the same!♥♥♥ We’re together!♥♥♥”

“Y-Yeah…”

I don’t fully get it, but apparently, she highly values my understanding of her, which is great.

…Still, assuming I fully understand her just because I can read her actions a bit would be foolish. I need to stay cautious not to overestimate that.

“…♥♥♥”

Each time a brief silence fell between us.

Yuu would gaze at me lovingly, up close, her lips twitching slightly.

It’s obvious now, but she’s trying not to ruin her pretty face.

It’s a small show of vanity, wanting to look good for me.

But she doesn’t hide or change the subject, showing she trusts my affection for her.

…Or maybe it’s unconscious. Maybe she’s not thinking at all, but that unguarded nature is also a sign of trust.

I can’t fully read her thoughts, but I’m starting to understand what kind of thoughts she has.

“…Nfufu!♥♥♥”

In bed, staring at each other up close.

She squirmed, rubbing her thighs together.

“Shouldn’t you put on underwear?”

I asked, worried about the semen still dripping from her.

“It’s fine!♥♥♥ It stopped, I think!♥♥♥”

“Got it.”

Relieved that tissues weren’t needed, I was floored by what she said next.

“Wanna check with your fingers?♥♥♥”

“N-No, I’m good…”

“Come on!♥♥♥ You can touch it!♥♥♥”

“…!”

Under the covers, I couldn’t see, but I felt her grab my right arm and guide it toward her crotch.

“No, no, it’s fine! My bad for worrying too much!”

“…Nfufu!♥♥♥ Nfufufu!♥♥♥”

Satisfied with teasing me, she giggled happily.

“Hurry up and get me pregnant, okay?♥♥♥”

“Wait on the pregnancy.”

“…♥♥♥”

“Hey.”

Our playful banter had chilling moments, especially when her arousal came up—always thrilling.

“…At least for now, keep taking the pill.”

“I know!♥♥♥ I won’t do anything to trouble you, Ren-chan!♥♥♥ I won’t get pregnant yet!♥♥♥”

“…Please. I’m counting on you.”

“Leave it to me!♥♥♥”

She nodded confidently, but… she’s lost control so many times. I won’t let my guard down.

“…”

“I took today’s pill, so don’t worry!♥♥♥”

“Good…”

She sensed my tension and answered quickly.

“Keep taking the pill for a while, please, I’m begging you.”

“Roger that!♥♥♥”

With a sloppy grin, she rubbed her cheek against my shoulder again.

“Good night, Yuu.”

“Good night, Ren-cha—”

We drifted to sleep, feeling each other’s comforting warmth—

—Or so it seemed.

A light leaked through the curtains by the large window to the balcony.

““—!!””

We both sat up.

We instantly noticed the light’s abnormality.

“Why… is there a light… in Ren-chan’s room!?”♥♥♥
