While Taking Care of My Shut-In Little Sister, I Somehow Ended Up Ejaculating Inside a Beautiful Girl - Chapter 12: While on a Date with a Beautiful Girl, We Somehow Crossed a Line (Part 3)

Chapter 12: While on a Date with a Beautiful Girl, We Somehow Crossed a Line (Part 3)

The shopping mall on a weekend was, as expected, pretty crowded.

Especially after lunch, when people were filtering out of restaurants. It was a bit quieter now, but it’d probably get busier again toward evening.

We hit the restrooms and regrouped, deciding to do some window shopping—except for one stop at a boutique.

“Mind if we check out some clothes?”

“Sure, let’s go.”

The mall’s second floor had a large open atrium with glass railings overlooking the first floor. Shops lined the perimeter, bustling with customers.

The boutique had a handful of shoppers browsing racks of clothes and displayed accessories, taking their time to enjoy the experience.

We stepped inside, greeted by slightly warmer air and soft lighting that felt cozy and inviting.

“This place has a great selection.”

“Does it?”

“Yeah, maybe ‘cause it’s a bigger store?”

Yuu’s impressive. Unlike her, who seemed to sense something the moment we walked in, I was clueless.

Sure, the boutique was spacious for a mall shop—about the size of a small supermarket. It could’ve been a grocery store in another context.

But looking at the displayed items, I couldn’t tell what made this place better than others. The info gap between guys and girls hit me hard. I was outclassed—!

…No, lumping myself with all guys is unfair to the world. Some dudes are fashion-savvy, and some girls don’t care about trends. In our hyper-informed society, gender differences outside biology are practically nonexistent.

I just need to admit my own lack of knowledge.

“Wanna try stuff on?”

“Can I!?”

“We’ve got time. Go for it.”

We didn’t have firm plans for the rest of the day. I had a few ideas, but nothing worth cutting our shopping date short for.

“Ehehe~♥ Ren-chan, you got tissues, right?”

“Yeah, why?”

“Watch out for nosebleeds~♥”

“What are you talking about?”

Yuu’s teasing hinted at some spicy mishap, but in a public place, that’d take a miracle—or deliberate effort. I’d shut it down if it came to that.

First off, “pervy thoughts = nosebleed” is such a cliché stereotype. Who even came up with that? It’s a funny visual, though.

“Oh, wanna see me try on underwear—”

“Nope.”

“Then come into the fitting room with me—”

“Not happening.”

“…Hmph.”

Don’t pout. That’s too much exposure. That kind of play is for pros.

She probably wasn’t serious, but I’d rather she just enjoy picking out clothes normally.

“By the way, Ren-chan, do you prefer cute or sexy styles?”

“I’m clueless about women’s fashion.”

I’m bad with fashion in general, men’s or otherwise. I buy my own going-out clothes and wear them, but I don’t exactly have a sense of style.

“You don’t have to be shy. Just tell me what you like.”

“…Cute’s good, I guess.”

“Oooh, sexy, huh…”

“Hey!”

“Hahaha!”

If you already know, don’t ask.

To clarify, I don’t dislike cute styles. Yuu would look great in either, probably equally stunning.

But if a guy’s standing next to her, whether it’s cute or sexy, he’d have a hard time matching her vibe.

It’s like how men’s casual fashion gets sidelined in couple outfits for similar reasons.

Chasing “cool” or “cute” or “sexy” is just flexing your taste or gender—it’s self-indulgent.

The best fashion, or grooming, respects the person next to you. That’s what matters most.

“You tend to dress plain when you’re alone, huh?”

“Of course. I’m not dressing up for you at those times.”

“R-Right… fair enough…”

Her deadpan response left me at a loss.

“Sexy stuff outside of loungewear, huh…”

“You don’t have to force it. Wear what you love. That’s the best.”

I’m not picky about clothes, so I’m ready to switch up my look to match hers.

Like colorless water. Like a chameleon. Like an octopus. I’ll blend into any vibe—

“I’m walking next to you, Ren-chan, so I can’t just dress however! ”

“Oh, uh, s-sorry…?”

Yuu’s surprising focus on clothes, her cute pondering as she picked outfits, was fresh and fun to watch. I could stare all day.

“Ren-chan, try this on.”

“What, me too?”

Guess I jinxed myself by playing the observer.

“I’m changing too, so let’s stand side by side after! ♥”

“…Alright.”

Might as well go along with her enthusiasm.

We tried on a few outfits, debating this and that, testing how men’s and women’s clothes paired together.

Carrying a shopping bag each, Yuu and I walked hand in hand with our free hands.

We left the mall, planning to stroll through town before heading to the station. Taking the bus was an option, but Yuu shot it down for some reason.

“That was kinda refreshing! ♥”

“Yeah, I’ve never picked out clothes that seriously before.”

“About that, sorry. I could’ve paid for your stuff tooo, you know?”

“Nah, I’ll buy my own clothes.”

In the end, Yuu paid for the outfit she picked for herself, and I paid for the one she chose for me. That’s how we ended up here, walking together.

“You’ve covered most of the date too, Ren-chan. Is your part-time job money really holding up?”

“It’s fine.”

“…”

Yuu shot me a skeptical side-eye. Doubting me?

“Wow, having a dependable boyfriend is so nice~…”

“Then act happier about it. You don’t believe me, do you?”

Her disappointment was too obvious.

“Huh? I thought you were just putting on a brave face.”

“I’m not that hung up on pride.”

“…Hmm?”

She gave me a mischievous glance, lips twisting into a playful smirk.

“If I was broke, I’d have begged you for help already.”

“Ugh, I didn’t need to hear that.”

We tossed lighthearted jabs back and forth, laughing.

Then—

“Ah!”

“What?”

Yuu stopped dead in her tracks.

“Look, over there!”

“…A park.”

Her excitement spiked as she pointed to a park that came into view as we walked through town.

It had a jungle gym with a slide, benches, swings, a horizontal bar, and a public restroom.

Nestled among office buildings and apartments, it felt oddly lonely in the afternoon, with no one playing or resting.

“Don’t you remember this place?”

“Hm…?”

I racked my brain, but nothing clicked. Yuu’s intense stare wasn’t helping me come up with any breakthroughs.

I had faint childhood memories, sure.

But a lot of them have faded, buried in the sands of time.

“All I can think of is… we played here a few times when we were little…”

“With who?!”

“Whoa!”

“Who’d you play with?!”

“Uh…”

Her sudden intensity threw me off. I dug through my memories…

…Oh.

“Back then, yeah, your dad and mom took us out, and we got lost, right?”

“Yes, yes! We were so excited to go out and play, we ditched them during shopping and ended up here!”

“Man, we were dumb. I followed you, and we wound up at this park.”

“Hey! Don’t pin it on me~!”

“Haha.”

I went along with the carefree Yuu (who didn’t think things through), despite warnings like “That’s dangerous” or “What about your parents?” and ended up here with her.

When was that…? Definitely elementary school.

“…Back then, we played together every day, huh?”

“Yeah.”

Yuu and I haven’t always been inseparable up to this age.

There was a time… when we briefly drifted apart.

“Right after we started middle school, right? You got all distant. I seriously thought you hated me. I was so down.”

“S-Sorry…”

“No, I didn’t mean it like that! I know you had your reasons, Ren-chan! So, it’s just a funny story now, like…”

“Still, I hurt you. You were so gloomy back then… because of me, right…?”

“Ugh, no! My bad! I didn’t mean to guilt-trip you—wait, why’re you laughing…? Hey, Ren-chan!?”

“Sorry, sorry, I teased you too much.”

“Ughhh~!!”

“Haha, just kidding. I’m not hung up on that stuff anymore. If you’re not either, it’s really just a funny story now.”

“…Right!”

Yuu’s relieved smile, as she patted her chest, was adorable. But this wasn’t exactly a laughable memory. Around that time, some heavy stuff happened—things I’d rather not recall.

Those moments and emotions still linger in my mind, like burn scars.

*

It was some time after I started middle school.

One day, out of nowhere, my little sister, two years younger, was bullied at school. She stopped going to school after that.

That sister of mine, who used to shine with a smile like the sun.

She became a shut-in.

A middle schooler visiting an elementary school every day to investigate must’ve looked bizarre to outsiders.

I was desperate—pouring everything into gathering info about what happened to her.

I thought leaving it to adults would fix things. It didn’t.

The bullying was swept under the rug for the adults’ convenience, and it felt like my sister’s future, one of her possibilities, was cruelly, senselessly snuffed out.

So I took action.

It was too late. Far too late for revenge.

But I couldn’t just do nothing.

Fueled by rage, my blood boiling, my body itching to move, I acted recklessly.

My once-smooth school life started to crumble.

My grades slipped, my health took a hit, and my mind grew jagged.

I thought I had it all together.

I thought I was handling everything—until she ended up like that.

With our busy parents gone, I acted like a parent, like a god.

Then that trust, that expectation, shattered in an instant.

My vision of the future, my sense of purpose, vanished without a trace.

The loss of a precious connection.

“What’s wrong with you?”

Yuu Onodera, my childhood friend, neighbor, and classmate—a beautiful girl—spoke up, maybe frustrated that we’d barely seen each other lately.

“Why’re you ignoring me?”

Her face was sharp. Was she that upset I hadn’t been around?—That’s the arrogant thought that crossed my mind then.

It pissed me off.

She didn’t know anything.

Or maybe she did know and was still bothering me?

Just shut up.

Be quiet.

Why’s she looking at me like that?

Get lost.

This has nothing to do with you.

—I said awful, heartless things. Over and over.

I must’ve made her cry so many times.

I was such a mess.

Completely broken.

“I don’t have time to deal with you.”

“—!!”

The moment I truly found her annoying, a chillingly cold voice came out of me.

Yuu’s face stiffened at my tone, at the expression I wore.

…It was a side of me she’d never seen. A dark, ugly side.

Selfish anger. Hatred. She took it all head-on, and finally, without hiding her frustration, she looked away, lips pressed tight, and turned her back on me.

Our relationship, already strained since my sister became a shut-in, seemed to end right there—

…Or so I thought.

It didn’t end.

And that’s why we’re here now.

*

That’s why we’re here, like this.

“It feels like we’re back in the old days… ♥”

The scenery hasn’t changed much, the nostalgic memories, the present that feels the same yet so different.

The warmth of Yuu’s hand in mine.

The feeling conveyed through our touching shoulders.

“…Yuu. Let’s go back, just a little, to how things were.”

“Yeah! ♥”

It was almost funny, when you think about it.

“This relationship we have now.”

This thing between us.

“Let’s end it.”

“…What?”

Yuu’s deep, abyss-like eyes widened in shock.

Those pure, engulfing eyes.

The color drained from her face.

“Ren… chan…”

Her voice was small but carried a heartrending cry.

“We’re done, as of today.”

Her eyes, staring at me, sparkled with a light born from everything we’d built together.

Rain clouds gathered overhead.

Defying the gray sky, a light leaked from her eyes.

Tears.

“No… you’re kidding, right…?”

Her trembling, fading voice whispered.
