While Taking Care of My Shut-In Little Sister, I Somehow Ended Up Ejaculating Inside a Beautiful Girl - Chapter 50: The Weight That Sinks Endlessly (2)

Chapter 50: The Weight That Sinks Endlessly (2)

Yuu, in just her bra and panties, practically naked.

“Ren-chan.”

Expressionless, her flat voice calls my name.

“Ren-chan—”

“Uwah!?”

Her long black hair trails like a tail as she leaps into my chest.

“Ren-chan, Ren-chan, Ren-chan, Ren-chanRen-chanRen-chan—”

She entrusts her entire body, her full weight, to me with complete trust.

Catching her, I lower myself to the floor to avoid hurting her.

“That was sudden.”

“Ren-chan… Ren-chan…”

…My legs are spread in an awkward M-shape, a bit embarrassing.

But she doesn’t care about my position—

“Ren-chan!”

“Nmu!?”

“Nchuuu~”

She steals my lips.

As usual, I don’t resist, and soon our tongues entwine…

“…N, Yuu. Hold on.”

“Mua… Huh…?”

I gently push her away, and her face falls with disappointment.

The transparent bridge between our mouths breaks, her wet lips trembling with anxiety.

“N… No… Ren-chan… More… More kisses…”

She sways closer like a ghost, but—

“Yuu. Come on, don’t push it. The floor’s hard on your knees.”

“…!”

Concerned for her, I sit cross-legged and invite her.

“Sit on my lap.” A suggestion for face-to-face intimacy.

Kissing’s easier this way, I’ve learned.

“—!♥ Ren-chan—!”

“Nmu.”

“Nchuuuuu!”

She straddles my lap without hesitation, legs open, unable to hold back, pecking my lips feverishly.

Her legs wrap around my waist, locking in a daisuki hold.

And so, we continue.

“Nchu… Ha… Rero… Chu… N… Puchu… Un… Chu…”

Pecking lips, connecting mouths, swapping saliva, tangling tongues, licking spilled drool—a passionate kiss violating each other’s mouths.

No pausing to breathe, just warm breaths mingling in a raw, intense kiss.

“Hyunhyan Ren-chan… Nchu… Hyunhyan Ren-chan… Chu…”

Her eyes don’t close.

Wide open, staring at me up close, her gaze glimmers eerily.

In her composed, expressionless face, her abyssal black eyes shine with an intense light.

A powerful emotion.

A burning desire, like a flame consuming her, manifests as her lustful love.

Her expressions of affection are accelerating.

“—Nha… Ren-chan…”

She pulls back, and I see her face.

Expressionless, her eyes half-lidded, dreamy, almost sleepy.

…And a large stain on her panties’ crotch, turning white to gray, symbolizing her arousal.

Not urine, but love juices soaking her.

Her hips move lewdly, grinding against me, stirring my desire.

Zuri zuri. Zuri zuri.

Her butt slides back and forth over my penis.

“…Nf. Ren-chan, you’re hard…”

“No surprise there.”

Guri guri. Kui kui.

She rubs her vagina against my erection through our clothes.

Even through fabric, I feel her warmth and wetness.

“Ren, chan…! Ren, chan…! Ha, ha, Ren-chan… Nn!”

“This is… bad!”

I vaguely realize, still in my uniform while she stripped, my head foggy.

“Ren-chan, Ren-chan, Ren-chan, Ren-chan, Ren-chanRen-chanRen-chanRen-chanRen-chanRen-chanRen-chan—”

“Wait, Yuu. I’m still in my uniform, gotta change—”

“Ren-chan♥Ren-chan♥Ren-chan♥Ren-chan♥Ren-chan♥Ren-chan♥Ren-chan♥”

Her calls turn into sweet moans.

Zuri zuri, guri guri, kui kui, she grinds her crotch against mine.

Her once-wistful expression now a melted, feminine face.

Mental arousal fuels her physical arousal.

I observe her transformation up close, its dynamics.

…Wait, hold on.

Are we about to do it right here in the hallway?

“Yuu, let’s shower first, then my room—”

“Your promised creampie♥”

“Yeah, so—”

“You’ll creampie me, right?♥”

“Yeah, but… Forget the shower, just, not here, my room—”

“Creampie!♥ Creampie!♥”

Her eyes dreamy, her face fully melted.

She’s in the usual flow toward sex.

Her body’s arousal switch is already flipped.

“All day, I waited…♥ Finally, Ren-chan’s gonna creampie me!♥”

“Got it. I’ll creampie you, just wait a sec.”

“Ren-chan’s creampie!♥ Your semen filling me!♥ I’ll get pregnant with your kid!♥ Have a healthy baby!♥ Build a family with you!♥”

“…Yuu? No pregnancy, that’s a no-go.”

No good. Her head’s full of creampies and pregnancy.

Too erotic. Her pregnancy obsession’s too intense. What’s with that thought process…?

But me getting flustered thinking she’s “erotic” isn’t much better…

“Creampie me♥ Impregnate me♥ Make me pregnant♥”

“No impregnating.”

“Ren-chan♥Ren-chan♥Ren-chan♥Ren-chan♥Ren-chan♥Ren-chan♥Ren-chan♥Ren-chan♥Ren-chan♥”

“Uh, Yuu…?”

Her face remains melted, but I swear I see heart-shaped pupils.

With overwhelming force, she grinds her wet crotch against mine.

“Yuu, hold on—‘Ren-chan♥Ren-chan♥Ren-chan♥Ren-chan♥Ren-chan♥Ren-chan♥Ren-chan♥Ren-chan♥Ren-chan♥’”

She’s not listening.

“Look, Yuu, let’s shower first—‘Ren-chan♥Ren-chan♥Ren-chan♥Ren-chan♥Ren-chan♥Ren-chan♥Ren-chan♥Ren-chan♥Ren-chan♥Ren-chan♥Ren-chan♥Ren-chan♥Ren-chan♥Ren-chan♥Ren-chan♥Ren-chan♥Ren-chan♥Ren-chan♥Ren-chan♥Ren-chan♥’”

Her legs, locked tightly around my waist, cross to trap me.

“Yuu, wait—‘Ren-chan♥Ren-chan♥Ren-chan♥Ren-chan♥Ren-chan♥Ren-chan♥Ren-chan♥Ren-chan♥Ren-chan♥Ren-chan♥Ren-chan♥Ren-chan♥Ren-chan♥Ren-chan♥Ren-chan♥Ren-chan♥Ren-chan♥Ren-chan♥Ren-chan♥Ren-chan♥Ren-chan♥Ren-chan♥Ren-chan♥Ren-chan♥Ren-chan♥Ren-chan♥Ren-chan♥Ren-chan♥Ren-chan♥Ren-chan♥’”

Her honey has already soaked her panties and my uniform pants’ crotch.

This is definitely hallway sex territory, I think, half-resigning, when—

She reaches for my pants, unbuckling my belt, and I start cooperating, unzipping—

DON!

““—!?””

DON DON!

““!?!?””

Yuu and I snap back to reality.

It’s so unexpected, so unforeseen.

—From above.

The sound of the floor being kicked—DON DON—from my sister’s room upstairs.

“Huh…?”

Yuu gasps in shock, but she’s not the only one.

I’m way more shocked than anyone.

“No… way…?”

Neither of us can see who’s making the noise, but we can’t tear our eyes from the ceiling.

“Rare… right?”

“Y-Yeah…”

Gulp. Our throats catch.

It is rare.

My sister lives so quietly, barely making a sound, her presence almost undetectable except for traces.

What’s with this floor-kicking? What’s her intent?

“Is something wrong…?”

“…”

We exchange looks, fixing our clothes.

Yuu hurries into her blouse and skirt; I buckle my belt and zip up.

Yuu, matching my serious mood, snaps back to sanity—her quick switch is endearing, though she keeps pressing her skirt over her wet crotch, looking concerned. It’s too erotic, so I avoid looking.

We head upstairs, Yuu tiptoeing for some reason, while I walk normally to Shiori’s door.

I call out, as usual, to the unopened room.

“Everything okay?”

‘…’

Pretty fake, even for me.

Maybe too casual?

Sweat beads on my temple.

There’s a presence in the room—she’s not sleeping, definitely awake, I’m oddly sure.

“Sorry for being loud. Gonna shower and shop. Need anything?”

‘…’

I don’t knock, knowing it stresses her out. I just call from the hall.

Was our downstairs noise loud enough to reach the second floor?

The noise pollution from Yuu and me.

When we’ve had sex in my room, Shiori never complained.

Maybe my room’s walls muffle sound better than the hallway.

Yeah… a closed room might leak less noise.

My room’s not soundproof, but it makes sense.

Su.

“…Hm?”

A piece of paper slides under the door—a small note, like from a cheap memo pad.

She used to do this when asking for shopping or communicating up close. Practically pen-and-paper talk.

It reads:

‘What were you doing?’

“…Nothing.”

I stifle my inner panic and answer.

Su.

Another note.

Four words:

‘Liar. Dirty. Worst. Hate you.’

“…!?!?!?”

Why such vicious words lined up like that!?

It’s like a punch to the head.

“(Ren-chan! Hold it together!)”

Seeing the note, I sway, dizzy, and Yuu steadies me.

My usually steady balance and inner ear face an unprecedented crisis.

W-Wait…

Did my sister just hate me?

No way, my vision’s shaking…

She hates me?

Why…?

What did I do wrong?

Why does she hate me?

I’ve done so much for her, but maybe because I’m a guy my age, acting on those urges, doing that stuff at home…?

Was I too much, and now she hates me…?

Oh no.

Oh no no no…

“…”

Yuu looks at me with worry, then glares at the door and note.

Wait, don’t get mad at her.

It’s probably—no, definitely—my fault. If I’d been more disciplined, considered Shiori upstairs, not let my guard down like Yuu did—I shouldn’t be true to myself. I’m not in an environment for that. I should’ve lived thinking of Shiori while at home—

“…Ren-chan, let’s go.”

“Y-Yeah.”

Yuu supports my unsteady body as we leave. Going downstairs, I nearly stumble, but she keeps me upright.

…Being cared for like this. Haha…

I don’t know why her harsh words, after years, hit me this hard.

Such an unexpected moment.

Yet a predictable situation.

Still, the damage is massive.

“…No way…”

I soon realize the immense weight of that damage—and Shiori’s presence in my life.
