While Taking Care of My Shut-In Little Sister, I Somehow Ended Up Ejaculating Inside a Beautiful Girl - Chapter 51: Approaching Chaos

Chapter 51: Approaching Chaos

“…No way…”

In the bathroom, I sit on a chair.

Yuu kneels before me.

Only now do I confirm the glaring abnormality in myself.

Chuko. Chuko.

“Ren-chan, does it feel good?”

“…Huh? Y-Yeah, of course. Feels amazing.”

Chuko. Chuko. Chuko. Chuko.

Nyuchi. Nyuchi. Nyuchi. Nyuchi.

“…Sorry.”

“Don’t apologize.”

I’m naked on the chair, my penis exposed.

Yuu, also naked, her hair tied in a bun, cradles it gently, lovingly, with both hands.

“If I keep stroking your cock like this, will you cum?”

She gives me a handjob, looking up with concern, asking all sorts of questions.

“Can your cock cum while it’s soft?”

“…Doubt it.”

Yuu casually checks male anatomy. Some guys might cum soft, maybe during sleep, but awake, at least for me, I need to be hard to ejaculate.

“Gotta be hard to cum, right?”

“Yeah…”

She nods, as if confirming, her eyes gleaming—not my imagination. She stares at my penis with fascination.

It peeks from her hands, limp, drooping like a dead turtle.

Pretty pathetic sight. Wish she wouldn’t stare.

“Aww, you’re embarrassed, right?♥”

“Obviously.”

She teases, reading my face. Of course I’m embarrassed.

My pre-erection penis is being fondled relentlessly.

“It’s so… different from when it’s hard. Weird…”

“Hey.”

She squeezes lightly, pokes it, enjoying its squishy feel.

“If I do this for hours, will it get hard…? Or just hurt…?”

“N-No, never tried that long… You don’t have to…”

She keeps caressing my soft penis with dedication.

“…If I do something more erotic, will it get hard?”

“You’re plenty erotic already.”

“Nf♥ Thanks♥ But if it’s not getting hard, maybe the stimulation—”

She stands abruptly. Her bowl-shaped breasts—not too big or small, perfect to me—her neat navel, toned limbs, her whole body ideal to me, moves before my eyes.

Blushing, she says, “It’s kinda embarrassing…” and perches lightly on the bathtub’s edge.

“…Ren-chan.”

“Hm.”

“Look closely.”

“…Huh?”

She slowly spreads her legs, facing me.

Her secret slit peeks from between her white thighs.

Her closed labia, lightly fuzzed at the top.

She places her index and middle fingers on her labia, slowly parting them.

Nucha… A wet, lewd sound.

Her peace sign, back of her hand facing me, reveals pink folds and holes—urethra, vaginal opening.

Her love-juice-soaked pink flesh glistens under the bathroom light.

“Look, look~♥♥♥ Kupaa~♥♥♥”

“—!!”

Her vaginal opening, lower down, twitches as if eager for my penis.

The small hole opens slightly with a hiku, closes tightly with a hikukku, and clear fluid seeps out.

Noticing my rapt gaze, Yuu opens and closes her labia with her peace sign, showing and hiding her vagina.

“Look, look~♥♥♥ …Ku-kupaa~♥♥♥”

“…!!”

Not fully aroused, she retains some rationality, her red face forcing a strained smile, acting lewd despite embarrassment. Her slippery fingers fumble, failing to keep her vagina open, hastily parting it again—an act that deeply stirs my desire.

—So erotic.

Too damn erotic.

I’m being shown something insanely erotic.

“…Ah!♥♥♥ It twitched!♥♥♥ It moved!♥♥♥”

Her obscene pose, sweet voice, mischievous expression.

Her full-body erotic temptation makes my lifeless penis twitch.

—Yet, no erection.

“…Sorry.”

“Don’t apologize♥♥♥ It’s not like there’s no reaction!♥♥♥ You’re responding to me, right?♥♥♥”

“Yeah… I guess…”

Yuu, with a sloppy grin, forgives my sluggish response…

But it’s weak. Too weak.

Until this morning, her gorgeous body and erotic acts would instantly arouse me, but now my once-rigid shaft is a shadow of itself.

“Still… bit of a problem…” Yuu murmurs, finger on her chin, tilting her head, pondering my useless penis.

“If this keeps up, I might not get pregnant with your kid… Maybe I should stop taking the pill for sure… I’d get pregnant right away…”

Her thoughts, at least what she’s saying, veer into dangerous territory.

“No, keep taking the pill, please! I’m begging you! I’ll fix this impotence…!”

“Ugh, kidding~♥♥♥ I wouldn’t do anything to trouble you, Ren-chan♥♥♥”

Not fully insane, just joking, it seems.

Joking… right? Still sane…?

“But… it’s about my precious husband and our future. Gotta think about worst-case scenarios♥”

“Yeah… sure…”

—Oh, this might be bad.

Thinking “if I’m impotent, she won’t get pregnant” is too optimistic.

I need to fix this fast, or it’s trouble.

“Since it’s not zero reaction… in the worst case, maybe drugs could work…”

“…!”

Here it comes—terrifying scenario.

I envision Yuu dosing me with an aphrodisiac, my uncontrollable penis pounding her, raw ejaculation, her getting pregnant as a student.

…Yeah.

I have to fix this impotence. Dangerous otherwise.

“I looked it up… impotence? Could be from lack of exercise or muscle strength, but that’s not you, Ren-chan. We had no issues with sex before, no drugs needed… So, considering what triggered this… it’s psychological.”

“…”

I stay silent, not even nodding, but Yuu seems certain.

Her earlier sloppy expression, dreamy eyes, and sweet voice are gone.

She stares at me, dead serious.

“Your cock’s been lifeless lately, Ren-chan.”

Her gaze is unflinching.

“It’s because you’re down… because of your sister.”

“Yuu.”

I cut her off to stop her from crossing into forbidden emotional territory.

“…Sorry. It’s nothing. Just… I couldn’t forgive her a little.”

“…”

I don’t press for her true feelings.

“…I’m the one who’s sorry.”

I apologize instead.

“No need to say it, but it’s not that you’re not attractive.”

“…Yeah. I get it. I know how you feel, Ren-chan.”

Yuu looks at my penis with a wistful, regretful gaze.

I feel an itchy awkwardness and blurt out something reckless.

“If it takes drugs or whatever, I’ll do it. As long as you’re satisfied, I’m fine with anything—”

“No way, Ren-chan.”

“…”

Yuu rises from the bathtub’s edge, crouches to meet my eyes.

“Those aphrodisiacs or stimulants have side effects. You know overusing them’s bad, right? I hate the idea of your semen decreasing. I want lots of your healthy semen creampied in me.”

“…”

Her bluntness hits hard.

…Still, her overwhelming feelings pour through.

“I don’t just want to have sex with you, Ren-chan.”

It’s not just lust, she continues.

“I want your kids. To live with my beloved you forever. Even when we’re old, wrinkled grandparents. Even after death, always together.”

“That’s… quite a peaceful and charming future plan…”

Her “after death” bit feels a tad unhinged, but it’s not surprising she’d pick such grand words to express her love.

“Peaceful? Charming? Ren-chan, do you really think so?”

“Huh?”

“Did you think my confession was a lie or exaggeration?”

“No…”

I don’t think it’s a lie or exaggerated, but her confession definitely has some metaphorical flair. Physically, humans can’t be together forever.

Why’s she putting so much pressure on me here?

Her sudden seriousness throws me off.

“Even if I’m reborn, I want to be with you forever. I’m so hopelessly in love with you.”

“H-Huh…”

What a passionate, bold confession.

With my useless, non-erect penis, what reaction does she expect? No cool response fits this situation.

“I love you too, Yuu. Probably more than you think. I’m serious enough to see my future as ours.”

Lacking wit, I speak honestly, then regret the heavy words.

I tried to match her intense feelings with sincerity.

“…Yeah. It makes me so happy you feel that way…”

“Y-Yeah, good…”

Her dead-serious nod, eyes locked on mine, flusters me. My counter-confession didn’t faze her…?

I’m the only one embarrassed. Frustrating.

Our bold confessions are surreal in this context.

Come on, penis, get up already. Wake up! It’s time to rise for her feelings. Useless…

“…But, Ren-chan.”

“Hm?”

She leans so close our breaths mingle. Her big eyes and long lashes flutter, the light in her pupils intensifying with each blink.

“You still don’t get the true depth of my feelings.”

“I think I do. I know you love me endlessly.”

I do. I understand.

She’s my childhood friend and neighbor who’s loved me for eight years.

Not a long-lost reunion or a distant lover, but a girl who’s been by my side, deepening her feelings over time.

—That’s probably not normal.

Despite years together, it’s not just a “comfortable bond.” She’s consciously loved me as a man, ensuring I see her the same way—a relentless effort and mental strength.

Even after her love was reciprocated, she’s not satisfied; her feelings grow stronger, deeper.

Compared to typical romance, it’s almost deranged.

…But for me, who’s given up on “normal,” it doesn’t matter if our love’s conventional. Our satisfaction is what counts.

So, the problem is—

“Nope. You still don’t get it,” she insists, leaning even closer.

I part my lips, expecting a kiss, ready for saliva—

Her face passes mine.

Chu—Puchu—Chu—Chuu—

“…Huh?”

Kissing sounds near my shoulder, my neck.

Soft lips touch me, a wet tongue—like a tentacle—caresses my skin.

It feels good, but… I’m thrown off.

“H-Hey, Yuu…”

“Ha—Rero—”

She straddles my lap (face-to-face again), licking my neck, hands roaming my body.

…Like an octopus devouring prey, restraining and caressing me with limbs and mouth.

I feel like prey caught by a predator.

“—Nn♥… Ha♥…”

Both naked, I let her have her way. With nothing else to do, I savor her smooth skin. Her firm thighs tense.

“—Nnn♥ Ha♥ Nn♥ …Ah♥”

She grinds her lower abdomen against my flaccid penis, moving her hips.

A grinding motion, like crushing something between our crotches, paired with soft moans.

“Hey… that won’t…”

I warn her I won’t get hard, but—

“—Ah♥ …You know, Ren-chan, I’m—not that pessimistic—Nn♥”

“What…?”

Confused by her antics, I try to read her thoughts.

Of course, I can’t fathom her mind now.

“Ren-chan’s… cock… Nn♥… Doesn’t have to… get hard right away…♥”

She keeps grinding, hands roaming my body, kissing my neck, licking my shoulders, collarbone—utterly perverse.

It’s like she’s using my whole body for masturbation, or taunting a beast with raw meat.

Her hips sway provocatively, as if daring me to penetrate her.

Yussa yussa.

Guri guri, nuchu nuchu.

Our lower abdomens, soaked with her love juices, glisten and string.

Pathetic… my penis stays silent.

“Fu…♥ Ha♥ Ha♥ Ha♥ Ha♥…”

Pausing, she seems to catch her breath. Leaning forward, she rests her chin on my shoulder, breathing heavily.

I wrap my arms around her back, hugging her gently.

“Nn♥”

She squeaks happily.

Her breasts press against my chest, her warmth and heartbeat pulsing through.

…Her heart’s racing, thudding fast.

“Ren-chan♥”

“Hm?”

“I’ll always love you so much♥”

“Me too, Yuu. I love you.”

“Nfufu♥ Nfufufufu~♥♥♥”

Her sloppy, happy laugh rings out, while my earlier tension melts into relaxation. Her sweet voice, once arousing, now soothes, almost lulling me to sleep.

My initial embarrassment fades. I enjoy her breaths near my ear, gazing at her fresh bun hairstyle, her black hairball.

I’m in a daze.

Like post-climax clarity without ejaculating.

…

“I think this kind of thing is a rite of passage,” she says suddenly, her words catching me.

“Rite of passage?”

“Yeah. Obstacles we have to overcome. Walls to climb.”

“I see…”

My foggy mind thinks, So my sister’s the wall? Like it’s someone else’s problem.

“That’s why I’m not pessimistic.”

“…Hm?”

Her words don’t fully register in my hazy state, and I hum vaguely.

“You loving your sister that much…”

“Yeah.”

Love… huh. My feelings for Shiori feel like obsession, but they’re rooted in familial affection, right?

“When I become your family, I’ll be loved as much as her… No, as your wife, bearing your kids, you’ll love me even more, right?”

“Yeah, I guess…”

My reply slips out, but it feels callous, like I’m dodging her.

To be fair, I’m not sure about the future.

Any vague plans I make stay fuzzy, never tying to concrete images or emotions.

As a high schooler, my parents’ money barely keeps me afloat.

But when it comes to college or a job—when the scene shifts—I don’t know what’ll happen.

Maybe I’ll have to do everything on my own.

I don’t expect anything from my future—no, I can’t. The future’s tied to anxiety, and I’m stunned by my own refusal to think about it.

“Hey, Ren-chan.”

“Hm?”

Her breathing, by my ear, has calmed.

“…Once your sister’s issue is resolved, okay?”

“Hm.”

Her voice is as sweet and pleasant as ever, but it carries a deep, secretive tone.

“When your sister’s problem is sorted, will you look only at me? Love only me?”

She tightens her arms around my back, hugging me fiercely.

“I’d do anything for you, Ren-chan.”

“…”

Anything, huh.

Taking her words at face value might be naive, but her intense feelings are clear, and I’ll need to respond responsibly.

“With you, Ren-chan, I can do anything. Go anywhere. So—”

She takes a breath and says:

“Love me more…?”

More, she says.

It sounds like her usual whispers of love… but—

More?

More than now?

…I thought I was already pouring my all into loving her.

“I already love you a ton, you know.”

I use a bolder term than “like” or “love,” hoping it satisfies her.

“…Yeah. …I know how you feel, Ren-chan.”

Her grip tightens.

Our lower bodies press closer.

“I know you think about our future, filling your head and heart with it… but…”

“Yuu…?”

Her voice, by my ear, is oddly flat, catching my attention.

“Look at me more.”

“…”

She releases my upper body, giving me freedom.

Sitting up, we face each other at a slight distance, and I finally read her expression.

“Please, Ren-chan. More.”

“More?”

“Yeah. More.”

She’s in that state again.

Blinking less, eyes wide open.

Her mouth barely moves.

Her overall motion subdued, as if barely containing her emotions.

A wistful hint in her rigid expression.

Her voice, steady to hide trembling, calmly professes love.

It’s the telltale sign of her mental arousal breaking past its threshold—her uncontainable feelings spilling out.

“Ren-chan. More.”

“…”

Yuu repeats “more,” her hands clasped tightly behind my neck.

Not pulling me closer, just staring straight at me, saying—

Love me.

“Look only at me.”

“Feel only me.”

“Love me more than anyone else.”

She keeps professing her love.

I’ve always responded to her whispers, but is my usual stance not enough for her now…?

We say “I love you” all the time.

Hmm…?

I should show my commitment to match her deep love.

…Same as always, I guess.

“I love you, Yuu.”

“More than anyone?”

“Yeah.”

“You’ll keep loving me forever?”

“Yeah.”

“Even knowing my true self?”

“Yeah.”

“…?”

“What’s wrong?”

I’ve been affirming everything to ease her fears—a full-on “yes to all.”

But her reaction’s off.

Normally, she’d dive into a kiss by now.

Normally, she’d be satisfied with my answers, her lust flaring up.

But this time, it’s different.

“…”

“What’s up, Yuu?”

She stares at me, silent for a long moment.

“…Sorry I couldn’t make your bento today.”

“No, it’s fine. How many times are you gonna apologize—”

“As an apology, I’ll give you my pussy.”

“—Huh?”

She stands.

Lifts her hips from my lap.

And there, right before my eyes—

Her faintly fuzzy pussy.

“…W-Wait, Yuu—”

“My everything—including this—is yours, Ren-chan. I’m giving it to you, so do whatever you want.”

“…Huh?”

Saying “I’m giving it,” she “kupaa”s her crotch closer.

Literally right in front of my eyes and nose.

I see her faintly hairy vulva, her parted labia, flesh swelling around it, closing in.

…What is this?

What’s happening?

What am I about to be made to do?

“Go ahead—eat it.”

“‘Eat it’!? That doesn’t make sense! Wait, wait, wait! This—”

I protest verbally, but—

If this is truly her expression of love, one of her ways, is refusing right? A strange hesitation grips me.

While I waver, her pussy fills my vision, blocking the bathroom light, casting a shadow.

Oh, God. Please save this lost lamb—

Let there be light—

But no salvation comes. The darkness is brought by none other than Yuu, the goddess herself, shoving her faintly hairy pussy closer.

She’s not stopping.

“Eat it. Drink it.”

“What’s ‘eat it’!? And ‘drink it’!? What!?”

Shouldn’t it be “lick it”—no, that’s not the issue.

“I couldn’t let you eat my bento at lunch today, so—”

“So!? So what!?”

She’s not teasing or joking.

I don’t get it, but—something. She’s hinting at something I don’t know.

“Eat it.” “Drink it,” she repeats, dead serious.

“Go ahead, dig in.”

“Wait—!?”

My world—my vision—is engulfed in chaotic darkness, like the dawn of creation.
