While Taking Care of My Shut-In Little Sister, I Somehow Ended Up Ejaculating Inside a Beautiful Girl - Chapter 81: Just for Fun

Chapter 81: Just for Fun

With Yuu still passed out on my lap, I managed to get her panties and skirt back on, and pulled up my own pants.

I did my best to make everything look normal again, but…

“Su… su… su…”

“(Yuu, wake up.)”

“Su… su… su…”

“(No good…)”

Yuu was still asleep. She was back in her original position—straddling me face-to-face, her chin resting on my shoulder. I was starting to consider either forcibly waking her or carrying her out of the restroom on my back.

Then—

Knock knock knock

“—!”

At the worst possible moment, a knock echoed in our stall.

This arcade’s women’s restroom barely sees any female visitors, and there are other empty stalls, yet someone was knocking on ours.

…Thanks to the precedent set by a certain someone sleeping on my lap, I’m starting to catch on.

They’re knocking because they know exactly who’s in this stall.

“Yuu-chan?”

“…”

As expected.

Yakko-chan’s voice came from the other side of the door.

“Taking forever in there, huh? Pooping? Seen Ren-kun? He’s been gone for a while.”

She sounded bored, almost listless.

“I wanna take the plush home. Let’s just leave already. The arcade reeks of cigarettes… it’s giving me a headache…”

Her tone with Yuu wasn’t much different from how she talks to me—her usual self.

“You listening? Come on, let’s go find Ren-kun together.”

“…”

“Yuu-chan…? Wait, is it really Yuu-chan…?”

Since Yuu was asleep, my silence meant Yuu’s silence. Yakko-chan, suspicious of Yuu’s lack of response, let out a slightly anxious tone.

“…W-Wait, maybe it’s not Yuu-chan…”

Realizing it might not be Yuu, Yakko-chan cut herself off mid-sentence and fell silent.

“S-Sorry, maybe I got the wrong person… my bad…”

With that, I heard her hurriedly leave the restroom.

“Phew…”

“…”

“Hm…?”

I thought I felt Yuu stir on my lap.

“…Ren-chan.”

“You’re awake?”

Our eyes met as she lifted her head from my shoulder, though I wasn’t sure when she’d woken up.

She fixed her slightly messy long black hair, looking at me directly.

Those deep, abyss-like eyes gleamed intensely.

“…What’re you gonna do about that girl?”

“Do about what…?”

She must’ve heard Yakko-chan’s voice through the door.

I couldn’t help but think she could’ve responded to Yakko-chan if she was awake.

“…Does Tsuki-chan still have a hold on you?”

“A hold?”

After a long pause, that’s what she said.

There was an odd atmosphere.

A hold, huh.

I felt like I’d glimpsed a reason why Yuu, despite being my girlfriend, was so wary of my relationship with Yakko-chan.

“…Back in middle school, didn’t something happen between you and her?”

“Nothing happened.”

“…Is that a lie?”

“It’s not.”

“…”

She blinked, her long eyelashes fluttering.

Her cherry-pink lips trembled slightly before parting.

“…I’ll just say it clearly.”

With resolve, Yuu looked me straight in the eyes.

“Even if you think ‘nothing happened,’ Ren-chan, it can still be a pretty big deal to me.”

“…”

I see.

If I dodge the question, I might be guilty in Yuu’s court. Her rules apply here, no diplomatic immunity. I feel like a spy abandoned by my country.

Still, this calculated back-and-forth with her feels kind of new.

“I met Yakko-chan in middle school.”

“I know that.”

Yuu nodded as I laid out the basics.

“It was a bit of a weird meeting, so I left a strong impression on her, and we started as friends. That’s it.”

I think I’ve mentioned this to Yuu before. When she first saw me with Yakko-chan, she interrogated me with wild accusations like, “Where’d you meet her!? Where’d you pick her up!?”

Yakko-chan and I became friends in middle school. Nothing more, nothing less. That’s the whole story.

“…That’s it?”

“That’s it.”

“…”

Yuu blinked at my firm answer, her eyes widening slightly with what seemed like surprise, or maybe unease.

“…W-What… ‘Weird’…? A ‘weird meeting’…? You mentioned meeting her before, but… what about other times…?”

“Hmm…”

Come to think of it, I don’t think I ever shared the specifics of how Yakko-chan and I started hanging out or what we talked about.

“I haven’t heard this…! I know you met Tsuki-chan when you were skipping classes, but which time!? Out of your eight skipped classes, which one!? What happened!?”

“Calm down.”

Yuu leaned in, eyes wide with intensity. Overwhelming.

I don’t even remember how many times I skipped, yet she’s got the exact number?

Eight times, huh… I skipped a lot…

Wait, how does she know something I don’t even keep track of…?

…No, that’s obvious by now.

“Ren-chan… are you hiding something about your relationship with Yakko-chan!? No way… something I don’t know…!? Ren-chan! I’m your girlfriend!! I’m the one who’ll be your wife!! I’m the one who’ll have your kids!! Only me!!”

“Calm down, Yuu—mph!?”

Chuuuu!

Yuu suddenly went for a fierce kiss.

I matched her passion, falling into our usual deep kiss, but this time she squirmed, rubbing her thighs and butt against my lap like a tantrum.

After a long exchange of lips and saliva…

“Mua…♥”

As our lips parted, a transparent thread stretched and fell.

Seeing her melted expression, I hoped she’d calmed down, but…

“You okay now, Yuu?”

“I’m fine, I’m fine, I’m calm, I’m fine, I’m calm…”

Nope, not calm.

Staring into space with a dazed look, muttering to herself, she was all over the place—clearly unhinged.

“I’m fine, I’m fine, I’m Ren-chan’s girlfriend, I’m Ren-chan’s girlfriend, I’m Ren-chan’s girlfriend…”

“Calm down.”

“I’m fine, I’m calm, I’m fine, I’m calm, I’m fine, I’m calm…”

She bit her tongue.

“—I’m calm. I’m fine. Because I’m your girlfriend now, Ren-chan.”

Maybe stumbling over her words snapped her back, as she lowered her gaze, took a few deep breaths—

“Phew…”

And met my eyes.

“…Sorry. I don’t doubt you, Ren-chan… but that girl… Tsuki-chan’s feelings for you, even if you try to brush them off or keep her at a distance, she’s so persistent, so stubborn, right? …So, I’m just a little worried…”

“…”

Looking back, the words “persistent” and “stubborn” fit no one better than my girlfriend, Yuu Onodera.

Not that I want to badmouth her.

Her mental toughness in that regard deserves praise.

“Worried… that I’d cheat with Yakko-chan?”

“Because… you’re so kind, Ren-chan. Too kind. You accept people endlessly, don’t you…?”

“I don’t think so.”

“You do. Because, look, you…”

She glanced up at me, then away, sneaking a peek.

I accept people endlessly…?

Including her, right?

So, the more I accept her, the more I fuel her anxiety.

…What am I supposed to do?

Rejecting her would make her panic, but accepting her endlessly leads to this insecurity.

…Love is tough.

Liking someone, wanting to be together—that alone doesn’t wrap it up. Humans, as social animals, are so complicated.

Not that I want to go back to caveman days…

It really hits home how complex human hearts are.

No wonder so many people lament that reality doesn’t go their way.

Aiming for your ideal outcome means, to some extent, trying to control the other person.

Focusing on that, achieving your ideal relationship requires knowing how to influence people. Taking the lead becomes essential.

…Thinking like this makes human relationships feel pretty cold.

If it’s about selfishly dominating someone, that’s problematic, but if love is at the core, how much is acceptable?

And we must be cautious—love alone doesn’t justify everything.

Abusers who hit their partners and claim “it’s out of love” are a prime example of love as an excuse.

Wielding love as a tool for selfish desires… childish greed.

But love isn’t always about sacrificing everything for the other person.

Balancing both your happiness and theirs is key… so, aligning what “happiness” means for both is crucial.

You work to eliminate misunderstandings and build the relationship together.

…But Yuu and I have talked endlessly about our vision of happiness.

Yet here we are. Is there a better way…?

All I want is to build a happy family with the person I love. That’s enough for my future.

That’s more happiness than I deserve, and I’m not asking for much.

Yet if it’s still not working, I must be lacking something.

I’m not asking for much, yet I’m unfulfilled.

I gave up on “normal” long ago, but I can’t even protect the “now.”

“…Ren-chan… no… don’t leave…”

“I’m not going anywhere.”

Yuu clung to me tightly, unable to hold back.

I’m painfully aware of my own inadequacy, but on the surface, I say things to reassure her.

“Ren-chan… don’t abandon me…!”

“Idiot, I’d never abandon you. Why would you say that? I’d never do that.”

“Ren-chan… stay with me forever…! Don’t leave me!!”

“I won’t.”

She looked ready to cry, voicing her fears.

She’s very, very unstable.

Oh no, at this rate—

“…I’ll just get pregnant.”

“Here we go.”

There it is.

“Ren-chan… if I get pregnant with your semen… if I have your baby… you won’t go anywhere, right…?”

“Wait. I don’t need you to get pregnant to stay. I’m not going anywhere.”

Yuu, sulking, threw out a wild threat.

Getting pregnant to keep a partner…?

What’s with that terrifying tactic?

I scrambled to stop her misunderstanding and runaway train.

“I can’t… before you leave, I’ll stop taking the pill…”

“Keep taking it.”

I stared into her eyes with a desperate plea, urging her to stay on birth control.

“I’d never abandon you.”

“But…”

“I’m grateful for you, and… I’m head over heels for you. You don’t seem to get that.”

“…”

She stared at me, dazed, for a while.

“…Then marry me?”

“Someday.”

“…Nfu!♥”

Her mood lifted a bit.

Her face lit up, her lips twitching as she tried not to grin.

It’s great that this eased her anxiety, but…

“So, when?♥”

“Uh… when!?”

“When will we get married?♥♥♥”

“Uh, well…”

“When,” huh…?

Get married… when…?

When do people even get married?

For high school grads, after getting a job, becoming an adult… then a bit later?

For college grads, after getting a job… then a bit later?

Specifically, when?

When do two people reach the right point in their relationship… no, being in love already clears that, right?

Then it’s just financial stuff…?

Wait…

Do I know nothing about this…?

If I’d been to a relative’s wedding, maybe I’d have a clearer picture.

Maybe hearing details from someone would help.

Should I get a part-time job at a wedding venue to learn the process? Front desk or hall staff should be doable for a high schooler…

“Hey, Ren-chan!♥♥♥ When’s the wedding?♥♥♥”

“When, huh…”

I’m so confused!

“…When do you think?”

In my confusion, I somehow threw the question back confidently!

What am I doing!? So uncool!

“Ehehe!♥♥♥ Flustered Ren-chan is so cute!♥♥♥”

“…”

Wait…

Was that a joke…?

Did I just get teased…?

“Then, since we’re keeping Tsuki-chan waiting, let’s go!♥♥♥”

“Y-Yeah…”

Yuu hopped off my lap so casually.

She stared into space for a moment, thinking, then said:

“What about Tsuki-chan? If we leave together, it’ll look suspicious, right?”

“…”

Yeah, no kidding. There’s not much to “do” about it.

What scenario is Yuu imagining where us leaving the women’s restroom together makes sense? Either way, I’m not taking that option.

“For now, you go out first and keep Yakko-chan in a spot where she can’t see the restroom entrance.”

“…Got it!♥♥♥”

After a slight pause, Yuu nodded cheerfully.

“I’ll let you know if it’s all clear!♥♥♥”

“Please.”

I watched her leave the stall in high spirits, then sat back on the toilet lid.

“…”

Sighing, I pulled out my phone to kill time while waiting for Yuu’s signal—

“…Hm?”

I noticed something.

Normally, in a situation like this, I’d expect that to happen, but it didn’t.

Zero new messages.

“…”

Yakko-chan, suspicious of my absence and wandering alone, didn’t message me.

Knowing her tendency to spam messages, that’s odd.

“Coincidence…?”

Just a whim? But forgetting to contact someone when you’re separated and trying to regroup isn’t that common.

“…”

For now, I stared at my phone screen.

“…Hello?”

‘Ren-chan~?♥♥♥ Where are you~?♥♥♥’

Yuu’s playful tone and sweet voice came through, probably calling in front of Yakko-chan. That meant it was time to leave the restroom.

“Just finished at the toilet.”

‘Oh?♥♥♥ Then we’re waiting!♥♥♥ By the billiard tables!♥♥♥’

“Got it. Be right there.”

I ended the call, pocketed my phone, and stood up.

“…”

Something nagged at me… but thinking about it alone wouldn’t give answers. Pointless.

Abandoning the endless maze, I left the restroom.
