.

Perhaps… was I being too foolish?

It’s not like I just graduated high school last year like Jiyoon—another year has passed since then. And yet, I actually pulled out my old high school uniform to wear.

To be honest, it doesn’t suit me at all. Maybe they were just praising me to be nice?

When I opened the door wider to show off my uniform, those few seconds—less than three—of silence where they just stared at me without a word…

…Could it have been them struggling to figure out what to say to me?

“…Ughhh… This is so embarrassing…….”

I don’t know.

Still, it felt a little unsettling to just stay silent when the room was quieter than I expected.

It wasn’t a big concern, but I felt like I had to say something…

And, most importantly—that thing stuck to Ujin’s… dick earlier while he was standing by the fridge.

…Like, when a girl gets really turned on… you know…

That stuff… that clings to a guy’s… dick…

…

Uh… that…

Seriously… juice?

Sorry, that’s a bit crude…

Ugh…

Anyway,

I was a little relieved when I realized they must’ve been having really quiet sex, but that just meant Jiyoon was completely satisfied already.

And it hadn’t even been 30 minutes.

“…I’m not that bad….”

Might Jiyoon just be way more sensitive than other girls?

Like, does she get overwhelmed even from just being lightly traced with fingertips?

Or feeling it while staying completely still after being penetrated?

I squeeze my thighs together, imagining what must’ve happened inside Jiyoon’s room—the things I couldn’t see.

Not that I’m exactly insensitive either. If anything, I lean toward the sensitive side.

Just last night, for instance, I left some embarrassing stains on Ujin’s bed.

When he pinned me down in his excitement and took me like an animal…

…When he forced himself against a place where he shouldn’t penetrate, pressing with all his strength…

The slick fluid stretched like threads between his lower stomach and my ass.

It’s still vivid in my mind—enough that I could easily use it for a lazy masturbation session if I wanted.

But compared to Jiyoon, who apparently dirtied the base of his dick that much in the time it took to use just one condom?

No way.

“….”

Setting aside whether sex feels good or bad—

Before that, it must mean she really likes him to be that way.

Jiyoon.

Likes Ujin.

“…Tch.”

Why does it have to be Ujin?

I get the situation, but why him of all people?

It’s not like he’s some other girl—it’s your little sister. What the hell?

My foot taps restlessly against the bed until finally—

Flick. I sweep my messy bangs back and turn, sighing heavily as I stare at the wall where Jiyoon’s room would be.

…Of course, it’s still a hundred, no, a thousand times better than her meeting some sketchy guy from a game.

But why did it have to be my boyfriend?!

Half the damn world is male…

“….”

Tap. Tap.

Around when will they finish? A sigh escapes me as footsteps echo from beyond the wall.

For a moment, I worry—If you don’t walk quietly, the lady downstairs will complain—but then Jiyoon’s sweet, melted voice follows.

– Hey. Seo Ujin. Water. I wanna drink first…

– …Here.

– Thanks…

The sluggish tone of someone who gamed all night, woke up, and is still half-asleep.

The indifferent tone that says don’t talk to me unless it matters.

The cold voice that snaps I have a headache, just be quiet for a bit.

None of those versions of her voice—the ones I know—reach my ears now.

Instead—

– …Why are you drinking straight from the bottle?

– Pffah… It’s our water, so what? …Oh, indirect kiss? That kinda thing?

– ….

– Hmm… Since we’ve actually kissed, why would that even matter? Pfft…

It’s disgusting.

To think there’s someone who talks like this is really my sister—

It’s enough to make me laugh bitterly.

“…Oh, unnie.”

“….”

Click.

When I crack the door open just enough to peek, the sight of two people whispers catches my eye.

A belt dangling loose at the waist.

Yet the pants are properly buttoned and zipped despite that.

The rest of his clothes are on, but draped over his sweat-soaked forearms.

And beside him stands a girl who doesn’t seem the least bit embarrassed—wearing neither panties nor a bra.

The gazes of the two, mid-conversation, simultaneously shift toward me.

“….”

…One is just as affectionate as always.

And the other—

“….”

Satisfaction.

A smugness with no intention of masking itself, mixed into the stare she fixes on me.

…You’re the one who took Ujin from me, Lee Jiyoon.

As if our positions were reversed.

So damn arrogant.

“Unnie. First, uh,… the ones from earlier are all used…”

“…Give them. To me.”

“Mm. Wait… – Oh, and Lee Jiyoon.”

“Yeah?”

“Get dressed. Here—you can borrow this.”

“…Ah, okay.”

“….”

Score: 1 – 0.

For a moment, I hold back laughter at Jiyoon getting scolded by Ujin before—

Thud. He casually tosses his shirt at her and walks toward me.

Then, opening the loosely clenched fist he’d been holding—

Right in front of me.

“…It’s gross, so just look. …Here.”

“….”

Three condoms, slick with so much translucent fluid they practically cling to each other.

Three condoms so bloated with the semen inside that the tips bulge unnaturally.

…Weirdly, the longer I stare, the more I just blankly think, That much came out…? as they sit there in his palm.

That he did this with Jiyoon.

In less than an hour,

three times.

And left such thick, dense streaks inside her.

Meanwhile, Jiyoon must’ve—

Gotten so wet it drenched the condoms like this.

So much that she really felt it all.

“….”

Have I ever made Ujin feel that good?

After we finish, don’t the condoms always only have about half this much?

That thought rolls around in my head, and the imaginary score I’d been tallying evens out—1 to 1.

…Honestly, if we’re comparing shock value, it’s probably more like 1 to 50, so—

I quickly erase the whole scoring idea from my mind.

“I’ll go throw these out now. It’s kinda weird to keep holding them.”

“…Where?”

“Jiyoon’s room, obviously…”

“…Don’t. I have a trash can in mine.”

Over Ujin’s shoulder,

Jiyoon slips her arms into his oversized shirt, the pristine white sleeves billowing as she shakes them out.

Glancing at her, I quickly avert my eyes and snatch the condoms from Ujin’s hand.

Throw them in Jiyoon’s room? Absolutely not.

You little pervert, putting on an act like you’re letting me have him when really, you’re just picking a fight with your own sister. Who knows what you’d do with these, huh?

So confiscated.

Then, as Jiyoon sniffs the shirt sleeve—probably checking if it smells like sweat—I eye her and add,

“Instead of just standing around in front of me, come inside already. And Jiyoon, you…”

“Yeah?”

“…We’re definitely done for today. Got it?”

“Okay.”

“….”

Huh.

She’s giving up more cleanly than I expected.

I thought for sure she’d cling and whine about it…

Or is she just saying that?

By the time the thought flickers through my mind, Jiyoon’s already walking back to her room.

Waving her hand playfully at us like it’s some kind of goodbye, even.

…Probably because she knows today isn’t really the last time she’ll have sex with Ujin.

It’s only been one out of fourteen days, after all.

I’ll let unnie have him for today.

That kind of vibe.

Like she thinks she’s already won by lasting till the end—easy enough to sway Ujin back to her side whenever she wants. That kind of naïve, cute little delusion…

“….”

But I have my own way around it.

Because the one who knows Ujin’s tastes best—

Isn’t you.

It’s me—his girlfriend.

“Phew….”

My grip lingers on the door as I glance at Jiyoon’s now tightly closed door one last time.

Exhaling a tense breath, I quickly scurry over to Ujin, who’s been idly looking around my room.

“…What, what are you looking at? There’s nothing worth seeing in here…”

“Oh. That stuffed animal just lying around is cute.”

“W-Wait, what…?”

“…Hard to choose, but if I had to, I’d pick that white teddy bear on the far left…”

“….”

“….”

Then, naturally, I press myself right up beside him.

Not close enough that our skin touches, but enough to faintly feel each other’s body heat.

Because Da-bin told me so last time.

Not that girls are much different, but guys especially only think about sex.

So if you give them even the slightest opening, they’ll interpret it their own way and start tearing your clothes off with no hesitation.

And then—

That’s it.

So next time,

why don’t you tell me about your first time with that secret boyfriend of yours?

“….”

“….”

…Did it work?

His gaze—until now fixed on the stuffed animals—now falls directly on me standing beside him.

On my usual tied-back ponytail.

On my usual single small earlobe piercing.

And on the one thing unusual—

The faint scent of room spray clinging to

my high school uniform.

“Unnie.”

“…Yes. Oppa.”

The mismatched terms of address.

No time to feel embarrassed—his reaction is vivid beside me.

Of course, calling him oppa doesn’t instantly make him hard.

He just turns his head faintly, exhales a slow breath, and the hand that had been still clenches and unclenches lightly.

But those small changes alone make me—

Hoping just maybe—

Not wanting to lose—

Do this.

“…Hey, oppa.”

“…Yeah.”

“Jiyoon’s not here, so I wanted to ask you… something.”

“…What?”

An awkwardly formal tone.

Surprisingly convincing casual speech.

A voice that grows quieter as I speak.

And—

…Family.

But laced with the shameful desires

only Jiyoon knows.

“…Oppa, when you normally fuck me…”

“….”

“N-No, that’s not—”

“….”

“…Sunbae, when you normally fuck me…”

Not the Ujin who always calls me unnie without fail,

but the one who treated me like a younger sister that time we had sex—

Now that I’m in uniform… like a junior.

…If he could see me as a slightly perverted junior he met in high school—

“I… kind of feel like you’re holding back.”

“….”

—and as just a hole for him to use whenever he’s aroused—

Then instead of the tender sex we’ve always had,

maybe it’d be like the porn he watches—

where the man fucks as rough as he wants until he’s satisfied.

That tiny hope slips out.

“…Wanting… to go rougher. But holding back because of me.”

“….”

Fidgeting with my politely clasped hands, I watch his expression.

“It’s okay.”

“….”

“…I really mean it. It’s okay.”

“….”

Because I’m the one who knows Ujin’s tastes best.

And because I’m the one who fits those tastes best.

…Unlike you, who has such pure sex that nothing spills past the door—

Even with your little sister home.

Even knowing she just had sex with that same sister moments ago.

Loud enough for her to hear—

With an embarrassed smile, I ask him to fuck me

the way he likes.

“Getting treated rough by you…”

“….”

“…I actually really like it….”

“….”

……Way more.

—than anything you could do.
