While Taking Care of My Shut-In Little Sister, I Somehow Ended Up Ejaculating Inside a Beautiful Girl - Chapter 121: Why She Felt a Bit Gyaru

Chapter 121: Why She Felt a Bit Gyaru

The train we were on had cross seats, all facing one direction like a bullet train or bus, not the long seats along the windows.

Naturally, Yuu sat beside me, while Yakko sat across the aisle.

“Wow! First time buying a ticket…!”

“Tsuki-chan, how socially inexperienced are you…?”

“It’s been a while since I’ve seen someone buy a ticket too.”

Ignoring Yuu’s sharp jab, Yakko looked thrilled. She held the small ticket carefully, glancing between it and the passing scenery, flashing cheeky grins at us.

“Why a ticket all of a sudden?”

“No real reason…?”

“Got it.”

In an era of digital payments and cards, Yakko’s old-school choice puzzled me, but she claimed it was nothing specific.

“Tickets don’t stay with you, right…?”

“Well, yeah.”

“Oh…”

Yuu’s blunt reply made Yakko droop.

She seemed oddly disappointed over a ticket. But it’s true—tickets are designed to disappear. Train tickets, bullet train passes, express tickets—they’re returned at the gate when you enter but swallowed by the machine when you leave.

That’s the “normal” way, though.

I decided to correct Yuu slightly.

“If you get it stamped at the station window before passing the gate, you can keep the ticket.”

“What, really!?”

“No way…?”

The long-haired black beauty and the blonde twintail beauty both widened their eyes at me.

Being stared at intensely by these two was a bit overwhelming.

“Even Yuu-chan didn’t know?☆”

“Sh-Shut up…”

Yakko’s teasing grin made Yuu blush faintly and pout. Apparently, Yuu’s response wasn’t mean-spirited—she genuinely didn’t know. It’s rare to want to keep a ticket, so no surprise there.

The old charm of Japan’s thoughtful systems and culture, kind to travelers’ memories, feels profound.

But as everything digitizes, such nuances might be forgotten. Advanced tech makes information easy to find, but obscure, analog knowledge gets buried. It’s a shame when preserved knowledge goes unused, but that’s just information’s natural selection.

I just happened to stumble across this tidbit and took an interest. Sharing it—or whether it can be shared—is another matter.

“How’d you know that, Ren-kun?”

“Saw it online.”

“Really…?”

Young people often learn old things through trivial triggers.

Still, with less life experience, relying on external knowledge is useful.

“As expected of Ren-chan!♥ So knowledgeable!♥”

Yuu leaned closer, and I gave a wry smile, letting her hug my arm.

“It’s just something I saw online—”

“As expected of Ren-chan!♥ ‘SasuRen’ for short!♥”

“…”

What’s that? Why shorten it? What’s the point? A pile of retorts jammed up, and I gave up. Yuu’s expression made it clear.

“…♥”

Basically, she wanted an excuse. A reason for me to naturally (kinda?) accept her affection.

As long as she could flirt with me, anything worked.

“Yuu-chan’s got heart-eyes.”

“Huh, for real…?”

Yakko’s casual comment made me glance at Yuu—

“…♥”

Her narrowed, dreamy eyes stared at me, no cartoonish heart-eyes like in anime or manga, just a deep, intense gaze.

“Wow, Ren-kun, you actually believed that…?”

“Wait, why’s Yakko-chan weirded out?”

“Because it’s weird.”

I don’t know why, but my reaction was a “no” for Yakko.

I didn’t mix fiction with reality. It’s just… with Yuu, it felt plausible—okay, I know it’s not.

Yeah, I get why Yakko was put off.

“Nfu♥”

Meanwhile, Yuu was utterly delighted, squeezing my arm between her soft curves.

“…”

“Nfufufu!♥”

My eyes were drawn to her chest. Incredible. Universal Breast Gravitation… er, Universal Gravitation.

Those two celestial bodies captivated my heart.

By the way, all three of us had shed our uniform jackets, layering casual clothes over our shirts or blouses when leaving the Hoshimiya house. Yuu, in a beige cardigan, could pass for a student from another school.

Being pressed by an unfamiliar beauty (pure-looking but with slightly gyaru-esque gestures) was thrilling.

“If you want, Ren-chan, I can wear heart-eye contacts next time!♥”

I must’ve stared crudely, but Yuu seized the moment with that suggestion.

“Heart-eye contacts? Those exist?”

“Yup!♥ Online or at specialty shops!♥”

“Really…”

News to me. A whole new world.

“Wow… where’d you learn that, Yuu-chan…?”

“Saw it online~♥”

“Huh…”

Yuu echoed my earlier line.

“Nfufu!♥ Look!♥ ‘Cosplay for your boyfriend’s tastes’ section!♥”

“Wow, really…”

Yuu showed me a contact lens site on her phone. Flashy, girly design, high-energy text about colored contacts, with product links at the end.

“…Hmph. If it’s about gyaru vibes, I’m way better…”

“…”

Yakko leaned across the aisle, peeking at our phones. Her thin coat over her blouse almost revealed her—uh, modest chest. Not that I’m judging! No hierarchy in chests!

Just describing the situation, not ranking anything—

“Ren-chan, natural tones better?♥ Or these reddish ones?♥”

“Uh, I don’t know much about it, so…”

“Ren-kun’d probably like these. You like foreign movies, right? So maybe something more Western—”

“Eh? For Ren-chan’s taste, probably these—”

“…”

Pushed by the two chattering girls, I looked at heart-eye contact samples.

A zoomed-in image showed a heart-shaped pupil reflecting light. Surreal.

I wondered how Yuu would look wearing them.

“—Tsuki-chan, why’re you pressing your chest on Ren-chan in the chaos?”

Yuu’s voice dropped slightly.

“You’re doing it too, Yuu-chan.”

Yakko matched her tone.

“I’m his girlfriend, so it’s fine!”

“You’re flaunting it. On purpose, right?”

“Huh? Us flirting is natural. Everyday stuff.”

“Talk about ruthless. I felt totally cucked watching you two.”

“Cucked? Ren-chan and I were destined to be together forever. You’re the one who suddenly got close to him.”

“In high school, when I was getting somewhere, you swooped in like lightning.”

“You swooped in!! You should’ve stayed just a friend!!”

“Friendship between guys and girls? You knew that wouldn’t last. And when I got close… what, you’re that insecure? You didn’t even wait for Ren-kun to reject me.”

“Misunderstanding much? Ren-chan and I are together because we love each other. Why can’t you get that?”

“You serious?”

“Why wouldn’t I be?”

Oh no, this is bad. Gotta stop this.

“Hey, both of you, calm down! Don’t make a scene! It’s rude to others…!”

I mentally apologized to the few passengers in the car, keeping quiet.

With Yuu and Yakko, I can’t steer things to an ideal resolution…
