While Taking Care of My Shut-In Little Sister, I Somehow Ended Up Ejaculating Inside a Beautiful Girl - Chapter 74: Confinement: Day Two

Chapter 74: Confinement: Day Two

“—And so, it comes to this.”

“Nfu!♥♥♥”

Morning.

The Onodera household.

Yuu’s bedroom.

On her bed.

My limbs restrained.

Perfect.

Almost the exact same situation as yesterday.

…Honestly, I had a feeling it’d turn out like this.

“Hah…”

I shrugged and gave a wry smile.

Not exactly cool, though.

“—So, today’s all about that kind of ‘play,’ huh?”

“Yup!♥♥♥”

In other words, a restraint play (?) where I’m stuck immobile on Yuu’s bed.

Using medical restraint bands, designed to minimize discomfort for the wearer.

“I’m grateful you agreed to free me for bathroom breaks and showers after I begged.”

That request was granted, thanks to Yuu’s mercy. But, on the flip side—

“…That means I’m stuck on the bed the rest of the time, right?”

“Exactly!♥♥♥ Instead of doing anything you really hate, I want you to do what I really want!♥♥♥”

It’s a questionable trade-off… but Yuu’s head is probably consumed by a certain desire.

“If it’s something I can do, fine… but just to be sure, can I ask what you really want?”

“Nfufu!♥♥♥”

Yuu stood beside my restrained bed.

She grinned, cheeks raised, and voiced her wish in a sweet tone.

“Today, too, I want you to fill me up lots!♥♥♥”

“As expected, huh.”

Yeah, I figured. Right on cue.

“Ren-chan… haa…♥♥♥”

Yuu beamed with delight, peering at me.

Her long, glossy black hair swayed like flowing silk.

Her cherry-pink lips parted slightly, letting out a heated sigh.

“Haa…♥♥♥ Ren-chan…♥♥♥ You’re so cute tied up!♥♥♥ So cool!♥♥♥ So wonderful!♥♥♥”

Her words were a bit much, but the way she tucked her hair behind her ear was oddly seductive.

Her eyes narrowed slightly, her expression feverish, as she sighed “hau…” through her slightly parted lips.

Her gaze was full of affection. Her face melted with adoration.

As she bent forward, I watched to see what she’d do—then she placed both hands on my shoulders.

And then.

“—Chu!♥♥♥”

“…”

She kissed my cheek.

“Chu!♥♥♥”

My forehead, too.

“Chu!♥♥♥ Chu!♥♥♥ Chu!♥♥♥”

My neck, collarbone, shoulders.

Kisses all over my body.

All kinds of kisses.

Gentle, pecking kisses.

Strong kisses, sucking my skin—clearly leaving marks.

And then.

“Chuuu!♥♥♥”

Finally, Yuu latched onto my lips.

“Mmmchuuu!♥♥♥”

As she sucked on my tongue, I responded, and we dove into a deep kiss.

Barely pausing to breathe, we swapped saliva, tangled our tongues, and shared warm breaths.

The deep, heated kiss went on for a while.

“Mua…♥♥♥”

—Eventually, we parted, as if mutually agreeing to pause.

A transparent bridge of saliva stretched between our lips before falling.

—But the confirmation of affection didn’t end there.

“Ren-chan…♥♥♥”

Though she pulled back, her face stayed close, locked at near point-blank range, staring at me.

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

Her lips called my name repeatedly, and with each call, her expression shifted to… blankness.

…Surely.

Normally, that’d signal feelings cooling off.

Anyone watching might think so.

“Haa…”

…Indeed.

Yuu let out a sigh so disappointed, so despairing, it could easily be misunderstood as normal.

Her behavior had taken a warped, bizarre turn.

“…”

Sighing while staring at someone’s face? Rude much? Or maybe my kissing sucked?

No way I’d think that now.

I’m not so dense I can’t read her expression.

The meaning of this blankness.

“It hurts… Ren-chan…”

“…Hurts?”

I stared straight into Yuu’s pained, blank expression and echoed her words.

“Tomorrow, Mom and Dad will probably be back… You’ll go back to your house…”

“Well, yeah.”

It’s obvious I’d return home eventually, but Yuu seemed deeply upset by the thought.

“You’ll just stay over at my place again, right?”

“…Is that okay…?”

“Okay or not—”

Didn’t she say something about her parents’ sex drive reigniting recently? I recall her joking about “maybe getting a much younger sibling.”

Even if that was a jest, I have no intention of disrupting the Onodera family’s harmony or lifestyle.

“…I was thinking we’ve been overdoing it lately… I’ve been staying at your place so much… Mom even scolded me…”

Right, Kiyomi did chew her out recently. Something about not wearing me out.

As if I’d ever get tired of Yuu now.

“It’s fine. I mean, it’s not like it’s a bother now. If your parents are cool with it, I’ve got no reason to say no.”

There’s no need for Yuu to hold back. It’s a huge help for me.

The food’s great, and with her help, chores go smoothly.

…And above all, it’s mental.

Being with Yuu—just being together.

That alone saves me.

Always.

“You don’t need to put yourself down, Yuu. You’re always saving me.”

If her hesitance in odd moments triggers her wild behavior, I’d rather avoid that… but that’s not the whole story.

If her lack of confidence or anxiety about our relationship is showing, it’s better for both of us to clear that up.

The less anxiety she feels, the better.

“…You saying that… makes me so happy…”

Yuu said.

Slowly, slightly haltingly.

As if she’d forgotten how to speak.

“…‘Happy,’ huh.”

Funny, right? She’s my mental anchor, saving me, yet I’m the one who should be happy.

“Yuu, I’m the happy one—”

“…!”

Yuu’s reaction was swift.

“—Mmph!?”

“Chuu…”

Suddenly.

A short kiss, lips lightly touching with a chu sound.

When she pulled back, that pained, blank expression remained.

“Ren-chan… I love you… Ren-chan… It hurts… I love you…”

“Yuu…?”

Behind her trembling, long lashes.

Her deep, black eyes held a crazed intensity.

Yuu.

“Ren-chan… Ren-chan… No… Ren-chan… I can’t anymore… Ren-chan… Ren-chan…”

She pleaded her pain relentlessly.

…No, maybe it’s what’s normally called “yearning.”

But for her now, that feeling’s so intense it’s agonizing.

“Ren-chan… I don’t want you to leave… Stay in my room forever. Stay here, let’s keep making babies… Breed me endlessly… Impregnate me endlessly…?”

“Don’t be ridiculous.”

Her emotions running wild, she’s spouting outrageous words and demands, but I’d like to think it’s half-joking.

As a healthy guy who sometimes thinks with his lower half, her provocative invitations hit hard, tempting me to give in instantly.

Of course, I can’t… We can’t fall into a decadent lifestyle.

On weekdays, we’re students with school. And at the Hoshimiya house, there’s my shut-in sister—Shiori, with her deeply wounded heart.

I welcome Yuu staying over, but I don’t want our healthy lifestyle to collapse.

…Wait, what’s “healthy” again…?

…We’re living so far from “normal” or “healthy” that I’m starting to question those terms.

But seriously.

As long as we live in society, we need to adapt—at least on the surface, following its rules—or things get scary later. Humans can’t do everything alone.

Sure, I want to believe love can overcome anything.

I know many kind people understand and support love.

But… sadly.

My family shows that the world isn’t always full of love for cherishing someone. Not everyone’s driven by understanding and support.

“…Yuu. Do what you want with me, but let’s keep our lives together proper. If obstacles block us, it’ll just make things harder down the road.”

“…‘Our lives together’… ‘down the road’…”

Yuu repeated only parts of my words—but it’s not like she only heard those, right?

Her thoughts are probably racing in a different direction, consuming most of her mental bandwidth.

“Yuu. You get me?”

“…Yeah… Yeah, I get it…”

Yuu managed a blank yet dreamy expression—a skillful feat (?).

Her emotions are so contagious.

Is she really okay…?

But if she understands my serious intent—not abandoning everything for love or lust but building a future together—that’s enough.

…Of course, she’s not incapable of understanding.

She just tends to spiral. So, I’ll keep reminding her not to sabotage her own happiness, our best shot at a future.

We have to build restraint, rationality, and a balanced lifestyle in a way that works for both of us.

“…”

“Yuu…?”

She stared into my eyes, lost in thought.

Even I can’t read her completely.

“…You’re… thinking so seriously… about us…”

Her speech was shaky, staring desperately into my eyes.

As if struggling to recall words.

“Your feelings… facing them head-on… with all your strength… accepting me… It’s crazy… I love you… Ren-chan…”

“…”

Yuu spoke blankly, eyes wide.

Like always—with that desperate intensity.

Her emotions saturated, barely containing the overflowing feelings, showing her lack of composure.

“Ren… cha… Let’s get married…?”

“Someday, sure.”

“Ren-chan… Let me have your baby…?”

…No, something’s different.

Her thoughts veering there is typical, but her speech seems more erratic than usual.

Is this what happens when rationality melts…?

“I want to get pregnant…”

“Hold off on pregnancy, okay?”

I respond mechanically, but I’m not letting my guard down.

If she gets too worked up and loses all reason, she might actually stop taking her pills.

To keep her from making such a dangerous decision, to prevent a disastrous future, to make sure she holds back in the end.

That’s why I need to put a stop to it. As Yuu’s boyfriend, I have a duty to help her with contraception.

“Ren-chan… my pussy’s already ready…”

“Huh?”

Yuu bent slightly, sliding her fingers under her casual skirt and thin shorts, pulling them off.

The crotch of her white shorts dug into her, stained gray.

Soaked.

As she removed them, the crotch stretched slightly, caught in her slit.

When the stretched fabric finally sprang free from her slit—

From the tips of her budding pubic hair… a drip of clear fluid trailed down.

“Look. It’s soaking wet…”

“I haven’t even done anything, right…?”

Come to think of it, I hadn’t even caressed her yet.

And yet—

“Just feeling Ren-chan’s love… it’s like I’ve trained myself to get wet…”

“Huh???”

Yuu, dangling her freshly removed shorts on one finger, tossed them aside.

Still blank-faced, as always.

Clothed above, bare below.

Her gaze locked on me, expressionless.

Honey dripped from her, trickling down her inner thighs.

“Just… from that…?”

“It’s your fault, Ren-chan… You’ve completely rewired my heart and body…”

“No… uh… well…?”

Honestly, half of me wants to protest it’s unfair, while the other half wants to accept it.

But… until now, I’ve lavished her with caresses.

We’ve exchanged heated sweet nothings… confessions of love, affirmations that make me cringe just recalling them. That’s all true.

Hmm…?

How should I think about this…?

What’s the right emotion to feel…?

No, thinking about what’s “right” shows how confused I am.

“Look… Look, Ren-chan…”

“I’m looking… but…”

I’m already looking more than enough.

Still, she kept saying “look,” standing at the bed’s edge.

Thrusting her hips slightly toward me, emphasizing her drenched vagina.

“Because of you, Ren-chan, I’m like this… So… take responsibility… look even more…”

My eyes were glued to her private parts.

I was staring so hard it felt like I’d burn a hole through her.

“It’s for you, Ren-chan… Your exclusive pussy… Look… I’ll spread it for you… Look at everything…”

Yuu spread her legs shoulder-width apart—in a shameless pose—using her right hand’s index and middle fingers to open and close her slit.

No, not spread-spread.

Schlick-schlick.

Her already drenched, sticky slit made wet, obscene sounds.

“Too erotic.”

On the reclining bed, propped up, I watched Yuu stand with legs apart beside me.

The angle didn’t let me see every detail of her private parts.

But my “son” was rock-hard.

Waking up restrained this morning, like yesterday, I felt a mix of “well, damn” surprise and “as expected” acceptance—a complex start.

Yet my “son” was now like, “What a refreshing morning!”—bursting with energy.

Yesterday morning, I was mostly sleeping.

What’s with this?

My shorts and underwear are painfully tight. I want to take them off.

But I can’t do it myself.

What now?

“Ren-chan… I’m so happy… You’re hard again… Getting excited by my body… So full of energy…”

Dripping honey, Yuu knelt on the bed, starting to strip my lower half.

Her fingers brushing between my shorts and skin tickled.

Even that slight touch made my penis harden more, for some reason.

“I’ll do my best…”

“Best at what…?”

Her cryptic words made me ask hurriedly. I had a bad feeling.

Usually, it’s—

“I’ll work hard to give birth to a healthy baby. So, Ren-chan, work hard and fill me up—”

“No babies!”

I gently forbade it in the same tone as before, but cold sweat trickled down my back.

I’ve slowly built trust that Yuu will ultimately hold back on pregnancy, but… thinking about it, that trust is flimsy.

It’s supposed to be built on experience—through consistent, protected sex with her.

“It’s so big…”

Removing my lower clothes, Yuu swallowed hard.

“My pleasure.”

What a weird greeting.

The unique embarrassment of exposing myself, the pathetic frustration of being restrained, and the mix of impatience and anxiety made me oddly tense.

“Already… as big as yesterday… so fast… You really feel the same as me, Ren-chan…”

“Well…”

Our mutual love, and lust.

That’s why we’re in this scene, being honest about those feelings.

“Today, too… thrust deep inside me… give my womb lots of baby-making stuff…”

“Uh, sure…”

“All day with Ren-chan… sex all day…”

She swallowed hard again.

“All day, huh… Go easy on me, Yuu.”

Feeling the intensity in her gaze fixed on my groin, I swallowed hard, too.
