While Taking Care of My Shut-In Little Sister, I Somehow Ended Up Ejaculating Inside a Beautiful Girl - Chapter 67: Into the Swamp of Decadence

Chapter 67: Into the Swamp of Decadence

“R-Ren-chan… why…!?”

“Why… seriously, why…?”

It happened in a flash.

Trying to shield Yuu from burns, we tumbled off the bed.

Then, failing to steady myself, I collapsed onto her on the floor.

Both of us were stunned by the bulge in my crotch.

“Ren-chan, your impotence is cured!?”

Yuu covered her mouth, shocked. I was shocked too. Why now? How? Countless questions swirled in my head.

“Well, I don’t know why, but… I’m hard.”

“…!”

Yuu, beneath me with hands and left leg on the floor, looked up with teary eyes.

Her gaze darted between my arms, noticing something.

“R-Ren-chan… but you’re hurt…!?”

“I’m totally fine.”

I brushed off her concern, feeling blood rush to my groin.

It’s only been a few days, but an erection feels so unfamiliar, almost novel.

Sitting on the bed’s edge, I glanced down at my half-pants tenting prominently.

My son had come back to life, casually setting up camp.

“R-Ren-cha…!”

Yuu, rising with me, undid my now-meaningless restraints, freeing me completely.

“Bed’s a mess…”

Watching her toss the restraints aside, I looked back at the bed.

Oyakodon splattered on the sheets and blanket. A quick clean-up’s needed for a decent sleep.

“Yuu, the mess—”

“—Ren-chan!!”

“Uwah!”

Yuu’s hands gripped my thighs, her face inching closer.

Her perfect features were still, but her movements were slow, her breathing rough—fusu-fusu. Her deep black eyes sparkled.

“Y-You’re… hard!? Now!?”

“Y-Yeah…”

Honestly, Yuu seemed more excited about my erection than I was.

“S—”

She started to speak, swallowing hard—gokuri.

Kneeling on the floor, she leveled her gaze with my crotch, staring intently.

“Can I… touch it…?”

“…Go ahead?”

Her “touch it” meant directly, apparently.

I lifted my hips slightly, helping her slide off my half-pants and underwear.

Bororon.

My penis sprang free from the thin fabric.

My trusty son, revived after days, basked in the cool air, as if saying, “Phew, finally out!” or “Back in the free world!”—lively as hell.

“…Sniff-sniff♥♥♥ …Kufu♥♥♥”

Sniffing my penis, Yuu briefly zoned out, leaking a gleeful smile.

“—Itadakimaasu!♥♥♥”

“Hey, you haven’t eaten lunch—”

Pak.

My penis’s head vanished into her mouth.

…As if replacing her spilled oyakodon.

Yuu…

“Ren-hyan hooinhin…♥♥♥ Oinho!♥♥♥ Nfu!♥♥♥ Oishii!♥♥♥”

With a sloppy grin, she started sucking.

As usual, she could only manage the head, her mouth full.

The sensation wasn’t as intense as her vagina, but it tickled something deep—my maleness.

Her unpolished blowjob left me wanting, its clumsiness oddly stoking my sadistic side.

Yet, I felt her improving with time.

Each time she took my erect penis, her skill grew noticeably.

My head, hidden in her mouth, was teased in that unseen space—tentative licks with her tongue’s tip, or bold, lewd strokes with its base.

Savoring her growing prowess, even a sense of conquest, I climbed toward climax—

—or so I thought.

“Ah.”

“Oinho!♥♥♥ Oishii!♥♥♥”

Not even being pleasured herself, Yuu moaned as if she were, licking my penis.

…That’s fine.

The problem wasn’t that.

The problem was—

“Wait, Yuu, this might be bad.”

“Oinho!♥♥♥ Oinho!♥♥♥ Heei!♥♥♥ Heei!♥♥♥ Ahihe!♥♥♥”

“Bad, bad, it’s coming! This is different! This—”

I felt something not ejaculation.

…Same exit, different source.

Not semen from my seminal vesicles or prostate through the urethra.

…Liquid from my bladder.

Urine.

I was feeling the urge to pee.

“Crap, wait, Yuu! Stop for a sec!”

“Mua…♥♥♥ …Eh…?”

I forcibly pulled her head away and leapt off the bed.

“Nooo…! Ren-chan, where’re you going…!? Don’t go…!”

She slumped on the floor, whining like a child throwing a tantrum.

I can’t just piss all over her room…

“Bathroom! Gotta go! I’m gonna leak!”

“Leak here!♥♥♥ I’ll drink it!♥♥♥”

“What’re you saying!? I’m going to the bathroom! Sorry!”

Ignoring her deranged ramblings, I yanked up my pants and shorts, rushing to the toilet.

*

“Phew… that was close…”

I managed to pee without leaking.

Too much happened at once; I forgot the slight urge from before lunch. Lesson learned.

Holding it in’s bad for the body anyway.

Washing my hands in the sink, I stepped into the hallway—

And there…

“What’re you doing?”

“…♥♥♥”

Yuu stood, grinning—not just smiling, smirking—her perfect face slack with a lovesick expression.

“Ren-chan…♥♥♥ You got hard…♥♥♥ It’s the power of love…♥♥♥ Amazing…♥♥♥”

“Y-Yeah…?”

Honestly, I don’t know why I got hard.

“A-And… you’re still hard… even after the bathroom…?♥♥♥”

“Uh… y-yeah…”

…To be really honest…

Her melted, dreamy gaze fixed on my crotch.

Still erect.

“You can pee… while hard…?♥♥♥”

“Well, it’s not impossible.”

Satisfying her sexual curiosity…

…But it was tough. Ejaculation’s meant to shoot with force, like a high-pressure water gun.

I struggled not to mess up the Onodera bathroom.

“Now, let’s see that penis!♥♥♥”

“Huh?”

Yuu’s at it again.

“Let’s see that penis!♥♥♥”

“…You mean, take off my pants?”

“Yup, yup!♥♥♥ As expected of Ren-chan!♥♥♥”

“As expected,” she says, like I nailed her intent.

“…No, that’s not it. I’m subtly pointing out your word choice is weird…?”

“Take off your pants!♥♥♥”

“Yuu?”

She’s not listening.

“…Can I shower first?”

“Let’s see that penis!♥♥♥”

“Back to that.”

Refusing her, she doubled down on “show me your penis.”

“Look, I just used the bathroom. Let me shower—”

“If you’re that worried, I’ll clean your penis for you!♥♥♥”

“Huh!?”

—Exactly.

Why I resisted her suggestion.

She still wants me to whip it out.

…Post-bathroom.

Even if wiped clean, urine’s scent lingers.

Underwear’s there to keep things safe and hygienic.

And she—

“Take off your pants!♥♥♥”

“Look, after a shower—”

“Now!♥♥♥”

“…”

…It wasn’t the worst scenario of her tending to my lower needs.

But it’s close. Does she have that kind of interest? A chill ran through me.

“Your penis finally got hard…♥♥♥ Inside my vagina… my womb…♥♥♥ It’ll shoot so much…♥♥♥”

“Yuu, listen—”

“It’s fine!♥♥♥ I don’t care!♥♥♥ I’ll clean it with my mouth and pussy!♥♥♥ I’ll polish your penis!♥♥♥”

“What’re you saying!?”

I felt the bathroom door against my back.

I was cornered.

“Nfufu!♥♥♥ Nfufufu~!♥♥♥”

Her face, breathing heavily, was inches away.

Her eyes, behind long lashes, narrowed lovingly.

Her rough breaths occasionally broke into stifled, moan-like “nn” sounds.

Her glossy lips parted, exhaling a hot “haa.”

“—Finally, I can get pregnant~!♥♥♥”

“Wait, I said no pregnancy!”

Spouting nonsense, she…

“But…♥♥♥ I can’t wait!♥♥♥ Let’s get married!♥♥♥”

“I said it’s too soon—”

“Nfufufu~!♥♥♥”

She leaned closer—

“—Nmu!?”

“Nchuuuuuuu!♥♥♥”

…It was too deep to call a kiss.

Long, intense, hot, and perverse.

“Ren-hyan!♥♥♥ —Nn, creampie!♥♥♥ Today, all creampies!♥♥♥ Tomorrow too!♥♥♥ The day after!♥♥♥”

“No, the day after’s bad! Your parents come back, right!?”

Pressed against the door, I felt her arms around my neck, her pressure overwhelming.

…Her body’s musky, female scent wafted over me.

…Wait, is it my erection? Or something else?

I hadn’t noticed her womanly scent this morning, but now it’s intense.

“Wait, seriously, calm down, Yuu! We’ll have sex, okay! But not the day after! We need boundaries—”

“Don’t care!♥♥♥ I don’t care!♥♥♥ Today, tons of creampies!♥♥♥ I’m getting pregnant today!♥♥♥ I’m becoming your wife today!♥♥♥”

“It’s too soon—Nmu!? Wait, hold—Nmuu!?”

“Nchu!♥♥♥ Ren-chan!♥♥♥ Nchuu!♥♥♥ My darling!♥♥♥ Doesn’t matter!♥♥♥ Nothing matters!♥♥♥ I’ll take all your semen inside!♥♥♥ I’ll get pregnant with your seed!♥♥♥”

“No pregnancy—wait, Yuu! Calm down—Nmu!?”

…No pause for breath.

Our warm breaths hit each other’s faces.

Tongues intertwined, swapping saliva in our usual fierce deep kiss.

“I knew it!♥♥♥ I believed!♥♥♥ Ren-chan, you do it when it counts!♥♥♥ It’s your nature!♥♥♥ I knew you’d creampie me today!♥♥♥ I believed!♥♥♥”

“What’re you—hey! Don’t pull my pants!”

“—Aha!♥♥♥ Penis!♥♥♥ Ren-chan’s splendid-sama!♥♥♥ Hellooo!♥♥♥ Let’s creampie a lot, okay?♥♥♥”

…Thus, on the first day of confinement, by midday, the restraints were gone.

In the Onodera hallway, our sex-soaked weekend was about to begin.
