While Taking Care of My Shut-In Little Sister, I Somehow Ended Up Ejaculating Inside a Beautiful Girl - Chapter 105: Unexpected Cooperation? (3)

Chapter 105: Unexpected Cooperation? (3)

Ahh… it’s pitch black.

The world is shrouded in darkness.

A lightless void conceals everything, as if my heart might be swept away into an endless abyss.

Please, at least give me some reassurance. Something to confirm there’s another presence here, some comfort.

My hands grasped at the air repeatedly.

Yet, I kept reaching out.

“…Nnh♥”

Softly, my fingertips brushed something like a gentle breeze.

What I held felt like a warm patch of sunlight.

Or perhaps, the pulse of life itself.

“Nnuh♥ Yaa…♥”

That sunlight let out a sweet voice, trembling with a jiggle as if startled.

Soft, slightly damp.

That sunlight clung to my fingers, quivering—

“Jeez, can’t hold back anymore?♥ No helping it♥”

Instead of pulling away, it pressed closer, offering itself, urging me to touch more, to savor it.

The universe expanded, enchanting me.

When her universe met mine—

A Big Bang.

Countless sparks of happiness burst forth.

“…”

My heart tripped into bliss.

My mind flooded with lush nature. The scenery of life’s beginning.

A vast ocean covering the stars, land rising from its surface, forming the world we live in.

Overflowing greenery, gentle sunlight, the babble of rivers, the chirping of birds—

This is how the world was born.

—Genesis, Chapter One: Creation, complete.

…No, just kidding.

I snapped back to reality.

“Ren-chan, was the water too hot?♥”

“It was perfect.”

“Ren-kun, this… doesn’t hurt?”

“It’s fine.”

Yuu washed my arms with slippery hands, while Yakko scrubbed my back with a body sponge. At my request, Yakko was using a bit more force.

—Yes.

I was in the middle of bathing with two beautiful girls.

…Blindfolded.

…Being washed by two beautiful girls.

“(How did this happen…?)”

Yuu and Yakko kept bickering after dinner. I was just panicking, but the “how did we get here” feeling was strong.

I think Yuu suggested it, Yakko jumped in, and since they were okay with it, I went along… or something like that?

Yuu’s leniency toward Yakko’s antics clearly has some ulterior motive, but—whatever.

It’s erotic.

This situation is just—

The steamy bathroom filled with the scent of soap, the sounds of washing echoing.

Slippery, scrub-scrub, slick-slick, scrub-scrub-scrub.

“…”

God, it’s so erotic…! Of course it is—the sounds, the smells, the feel! My skin’s being touched freely by attractive girls!

…But I can’t see! Nothing!

Normally, I’d see and touch Yuu’s alluring body!

It’s right there if I reach out! I can feel Yuu washing me with her slippery fingers, but I can’t experience it with all my senses!

What a struggle…! It’s too tantalizing, and my buddy is getting antsy—

…Wait.

Maybe it’s because I can’t see that it’s so erotic.

I’m feeling intense arousal from the sounds, smells, and touch alone.

That soft, soapy skin, smooth and warm, the living heat—I want my whole body wrapped in it!

…But! This is just a bath! We agreed beforehand—no funny business!

“Haa…♥ Haa…♥ Nfufu♥ Haa♥ Haa♥ Haa♥”

“…!”

Yuu’s ragged breaths and sweet, ticklish voice hit my ear. A shiver ran down my spine.

“Ren-chan…♥ Sorry, it’s on hold for now…♥”

“Guh…!”

“Hold back…♥ I-I’m…♥ trying hard to hold back too…♥”

Yuu’s clearly struggling too.

She wants to dive into carnal desire, but she’s desperately suppressing it.

“…Saying that, but don’t start up like at lunch. You two get horny so fast… You said no, right…?”

Yakko’s exasperated, slightly sulky voice came as she scrubbed my back harder.

“…”

“…♥”

“…”

A damp silence… maybe?

Only the sounds of slick-slick and scrub-scrub filled the bathroom.

“By… the way.”

“Hm?”

But then—Yakko swallowed hard, her voice trembling slightly.

Her hands scrubbing my back felt hesitant.

“This… really… doesn’t hurt?”

“…? No, it’s fine. Thanks, it’s just right.”

“Oh… okay…”

Yakko’s voice shook behind me. She gulped audibly.

She seemed scared, but her scrubbing was normal. Just right. That’s certain.

Maybe she and Yuu exchanged some meaningful glance, and Yuu’s intensity spooked her—I imagined such a baseless scene.

“…Tsuki-chan. Focus on washing.”

“I-I know…!”

Yuu’s slightly scary tone made Yakko hurriedly scrub my back again.

Guess it wasn’t about fearing Yuu.

“What? Big pimple on my back or something? Haha—”

“…”

“…”

“Huh… haha… ha?”

I laughed, hoping they’d join in, but both Yakko and Yuu went silent, leaving only the awkward quiet and the sounds of them washing me.

Huh… not the vibe I expected.

I thought Yuu would go overboard, and Yakko would reel her in, shocked. That kind of scene.

“Hey.”

““…!””

“Ah… no, sorry, I mean—”

I think my voice sounded scary. Apologizing for startling them, I made a request, mainly to Yakko.

“No need for my butt. I’ll wash it myself.”

“—!? W-What—”

Yakko seemed flustered, protesting as if offended.

“I didn’t touch your butt!”

“Liar, you perv~! Secretly naughty girl~!”

“I said I didn’t touch it!”

“Huh!? Wait, what are you doing to my Ren-chan!? I didn’t allow touching his delicate zones—”

“I didn’t! I didn’t do anything!”

“I feel in danger! I’m not taking the towel off my crotch, no way~!”

“Huh!? I-I’m not interested in your… thing! Not at all!”

“Suuure, after you had your way with it earlier~”

“Ugh, so annoying! That’s harassment, Ren-kun!”

“…Ah♥ Thuggish Ren-chan… kinda hot♥ Do it next time…♥”

“Yuu…?”

“Yuu-chan…?”

Yakko’s flustered reactions were amusing.

I couldn’t see with the blindfold, but her face was probably red with anger.

Yuu, meanwhile, seemed to have tripped into another world…

Soaking in the tub with them.

Still blindfolded, I was close enough to hear not just their voices but their breaths, pressed against both girls.

…This tub’s bigger than mine; we don’t need to be this close… But pointing that out would probably stir trouble, so I kept quiet.

Occasionally, Yakko cautiously touched me, earning Yuu’s disapproval. Those exchanges didn’t last long—Yuu got genuinely grumpy, so I gently warned Yakko.

We quietly savored the warmth spreading through our limbs. Bathing feels like satisfying a core desire, though not quite a “fourth” one.

“~♪ ~♪~♪♪”

“Oh, I know that one.”

I reacted to Yakko’s vague humming.

“No, Tsuki-chan, it’s ‘~♪’ then ‘~♪ ~~♪♪’.”

“Ugh, Yuu-chan’s so picky.”

As we got used to bathing together, conversation flowed naturally.

“But yeah, Yuu’s pitch sounds right.”

“Ugh, even Ren-kun’s siding with Yuu-chan~? I think it’s ‘~♪ ~♪~♪’~”

“Didn’t that change a bit?”

“Is Yakko-chan secretly tone-deaf?”

“Huh?? Wanna bet, Ren-kun~?☆”

“Oh? Confident, huh? Bring it on—Yuu will!”

“W-Me!?”

“Lame, relying on others…”

“Winning’s what matters!”

“Isn’t Ren-kun bad at singing…?”

“Who’s bad?”

“I didn’t say that.”

“…I’ve never said I’m bad.”

“Oh? So you’re good~?☆”

“Of course—Yuu is!”

“Still relying on her… Yuu-chan’s probably good, though.”

“Yeah, I’m decent—”

“Yuu nails most songs at 90% or better!”

“Proud, huh, Ren-kun…”

“Ren-chan…♥ I’ll live up to your expectations♥ I’ll crush any tone-deaf competition with my skill♥”

“—Hear that? Brace yourself, Yakko-chan.”

“Sounds like you’re getting crushed too, Ren-kun.”

“I’m not tone-deaf.”

“We’ll see~♪”

We bantered about singing for a while.

“…By the way, sometime… whenever’s fine…”

““?””

Yakko fidgeted, trying to bring something up.

Her mischievous vibe likely shifted to embarrassment. Her atmosphere was easy to read.

“…How about… karaoke, together?”

“Sounds good.”

“If Ren-chan’s going…”

“Yay…! It’s a promise, both of you!!”

“Sure.”

“Yeah, okay.”

Her cute suggestion got my instant nod, and Yuu agreed, not entirely uninterested.

…Karaoke, huh.

I’ve been a few times, but maybe I should practice…

“Should we invite Nijouin or Mizuno?”

“Ah.”

““?””

Just as the karaoke plan solidified, Yakko made a sound.

What’s up? Did she already talk to them?

“…Can you invite them, Ren-kun?”

“Why?”

“…”

Blindfolded, I couldn’t see her face—

“…What, shy?”

“Cuz…”

“Come on…”

So childish, yet cute, Yakko.

…But I had to be firm.

“You invite them, Yakko-chan.”

“Why?”

Her eyes are probably teary, desperate.

It’s not that embarrassing.

“No need to be shy. They might not be free anyway, so just ask about their plans to start.”

“E-Even if you say that…”

Just normal communication, but… it’s tough for some, I guess.

“Reiko-chan seems busy…”

Yakko’s so timid. I thought she and Reiko-chan—Nijouin—were close.

She’s holding back.

…I wanna take this blindfold off. Seeing her face would give me more clues, but not now. After the bath.

“Why push me away like that…?”

“Ugh…!”

I pictured her teary eyes.

…She’s good at being cute in weird ways. I’m just saying show that to Nijouin.

“If I contact girls casually, Yuu gets mad.”

“Of course! Ren-chan meeting another girl one-on-one is cheating! No cheating, absolutely!”

“See?”

“…Ren-kun, you okay with that…?”

Yakko sounded worried, but this is Yuu’s nature. I’m used to it.

When I have to do something that worries Yuu, her jealousy flares, but it’s not hard to manage.

“Then if Yuu-chan’s so strict, she can contact them…!”

“Why me?”

“Wahhh!”

Cold Yuu shut her down.

But kind Yuu felt a bit guilty, whispering to me.

“(Ren-chan. That’s a no, right…?)”

“(…)”

I nodded. Yuu got my intent.

As friends, I want to see Yakko grow into someone who can casually invite others.

“…Who’s it for?”

“Hm?”

“—Huh? What’d you say, Yuu-chan?”

“…Nothing…”

Yuu’s words dropped off, as if lost in thought.

“…”

“…”

Even blindfolded, I felt her gaze until we left the bath.

Probably her discontented stare.
