…Huh?

Just that much?

…Tch. Unbelievable.

I’m the one who allowed you to sleep with Woojin.

So why the hell are you acting like you’re the one in charge here?

“Mmm… So unnie only got to do it once in a whole hour.”

“Wh-what kind of crazy talk is…!”

“…Just saying.”

“…”

“Strange. Seo Woojin—when he’s with me, he can’t even talk properly. Just slams into me like he’s starving for it…”

“…”

“And used condoms… He doesn’t even bother tying them before pulling out a new one.”

“…”

“Lee Jiyoon. Stop.”

It should be the other way around.

Logically, you should be bowing your head to me in gratitude.

But instead,

…why are you, the one who had to beg for my permission,

acting like you’re Woojin’s girlfriend?

Without my say,

you’d be stuck in your room sucking on your fingers.

Forced to listen to the sounds of my pleasure from next door,

jerking off in misery.

“What? You can’t possibly be satisfied with just one condom either, right?”

“…It’s not like today’s our only chance. We still have two weeks left.”

“But only once today…?”

“Hayoon-noona decided it, so just shut up and follow along.”

“No. At least three—no, four times…”

…Ah.

I get it.

Since you have to break up clean once the two weeks are over, you’re making your last desperate stand.

Whatever.

Not my problem anyway.

“…Hey. Lee Jiyoon. …Just don’t borrow Woojin.”

“…What? No. Why give and take back?”

“Because you’re picking a fight with me…!”

“…Oh, feeling insecure?”

“Ins—”

“If you’re his girlfriend, but can’t make him feel better than I can… then you can still take it back. Mm-hmm.”

“I told you to stop. Lee Jiyoon.”

My place.

Whether it’s because she’s obsessed with the title of “Woojin’s girlfriend” or not—

Jiyoon hides behind Woojin’s stern-faced figure, peeking at me with a mocking smirk.

I don’t think I’ve ever seen her make that face at me before—but the thought fades as Woojin steps between us with a sigh and approaches me.

Then,

keeping his voice low so Jiyoon can’t hear,

(whisper whisper)

“…I’ll apologize for her. Noona. I think she’s… given up on holding back.”

To him, I reply—

loud enough for Jiyoon, who’s still staring at me, to hear.

Clear and crisp.

“…Don’t bother. Just… don’t sleep with Jiyoon.”

“Noona.”

“I gave you to her out of generosity, but she keeps crawling over me…! Acting like she’s somehow above me…!”

“Jiyoon doesn’t usually act like this.”

“…Still…”

“I’ll talk to her properly once we’re inside. Tell her to knock it off.”

I don’t like it.

Stealing time alone with Woojin, then having sex like it’s nothing.

Woojin standing in front of me—but taking her side.

All of it.

I hate it.

…But.

“…And what Jiyoon said earlier—about doing it six, seven times? Don’t believe her. She was bluffing.”

“…”

“There’s never been a time… when she made me feel better than when you called me oppa.”

“…”

Until just now, he’d been whispering—

but now, Woojin says it outright,

loud enough for Jiyoon behind him to hear.

Clear and crisp.

I make him feel better than her.

Even if I don’t like Jiyoon,

I trust Woojin.

Because I believe in him.

“…Fine. Three. Happy?”

(snatch)

One.

Two.

Three.

Instead of handing them to Woojin right in front of me, I toss them at Jiyoon’s feet from afar, staring her down.

“…One hour. If you take longer, I’m breaking the door down.”

“…I don’t mind if unnie watches, though?”

“Hey. Lee Jiyoon.”

One by one, she bends down to pick them up.

“I don’t want to see it, you psycho. …Disgusting.”

“…Shame. It’d be a good chance for you to see just how much Woojin enjoys me.”

“Just get inside already. Talking to you is making my head hurt.”

Woojin gently nudges Jiyoon toward the room.

“…Stick to the time.”

“Yeah, yeah.”

As if to tell him not to push her, Jiyoon grabs his wrist and pulls him inside.

“…”

“…”

Woojin flashes me a reassuring smile.

…This is amazing.

I never thought I’d be able to openly say such awful things to unnie.

Not in a million years.

“…Why provoke her like that? You’re gonna get slapped.”

“Shh. Lower your voice. The walls are thin—if unnie’s listening, she’ll hear everything.”

Three in total.

I toss the condoms I swindled from unnie onto the pillow and head to the bed with Seo Woojin.

…Despite acting all proper earlier,

the second the door locks, Woojin’s hands grow filthy.

I yank his wrist back.

“…Guess I can’t pin you against the door and fuck you yet.”

“You mean yet implies you will later?”

“Depends. Right now, Hayoon-noona seems really pissed at you.”

“…Ugh. Seo Woojin, you’re just making things worse between me and unnie…”

“It’ll be fine. Things will work out.”

“…In a lewd way?”

“Something like that.”

“…”

Forced onto the bed, head tilted back,

…I lean in first to lick the lips of a man cheating on his girlfriend with her little sister.

A brief touch.

(lick) (lick)

Sounds unnie could never hear,

…before being shoved roughly onto the bed,

the slick, obscene noise of tangled tongues,

filling the room,

my mind,

completely.

“…Hey. Hold the pajamas you’re wearing in your mouth for a sec.”

“Why? Don’t wanna take them off yet?”

“Just bite.”

“…”

A stark contrast to the kindness he showed unnie earlier,

this Seo Woojin is consumed by lust.

…I wonder if unnie’s ever seen him like this.

Of course—there’s no way she has before me.

She’s too much of a coward to let him creampie her…

There’s no way she’s above me.

Smirking in smug satisfaction, I obediently bite the hem of my sleep shirt.

Guess Seo Woojin really…

“…Ha.”

“…”

“Had a feeling… You really weren’t wearing anything under this.”

“…Pfht. Could you tell?”

Despite not doing anything,

just bickering with unnie earlier—

I was already soaked,

…no underwear,

the fabric clinging to the flushed,

pink peak underneath.

Seems he noticed.

“No way I wouldn’t. That’s why I checked.”

“…Should’ve just stripped me yourself. I deliberately kept my mouth shut, waiting for you to do it.”

“Things like this are hotter when the girl shows it herself.”

…Pfft. You’ve got weird tastes.”

“Like you’re one to talk. …Fucking your girlfriend’s sister like some degenerate.”

“And you fucked me raw while dating unnie…?”

“…”

“…Besides, you’re only doing this… because you’ve got something in mind.”

“…”

“…Think they call it ‘sister sandwich’ or something… …Fucking perverted.”

“…Too loud. Just bite the damn pajamas again.”

“…You total freak. Seriously…”

As his hands tug down my pants, I lift my hips slightly to slide them off,

followed by panties transparent with slick strands stretching between them,

still biting the shirt with an innocent smile,

…until I ruin Seo Woojin’s neatly kept outfit myself.

(peel)

Sweater—

Don’t need it, so off.

Shirt—

Stop playing with my breasts and help me undo the buttons.

Belt—

Toss it aside. Who cares if it makes noise?

Pants—

Oh, these can go on the desk.

And finally, the underwear already radiating heat…

“…Lee Jiyoon. Why’d you stop undressing me?”

“Pfft… Things like this are hotter when the guy shows it too.”

“…”

“…Well? Hurry up and show me, you cheating, lust-driven perv—”

“…”

“…”

Tossing them outside where unnie could see would be my style…

…But she might actually kill me.

Maybe I’ll just leave them by the pillow?

“…This is only half hard, right?”

“More or less.”

Unlike before,

his cock now looks like it’d barely fit in my outstretched hand.

Sitting on the bed like a chair, I trace the thick veins running along its shaft up to the swollen tip,

my heart pounding as memories of the other day resurface.

…So that thing,

ramming deep inside me,

slamming against my cervix,

(plap)

(squelch)

…pumping cum,

then pulling back,

(thrust)

(plap)

(thrust)

before burying in again,

(spurt)

spilling everything left—

even seeing it in person, it’s hard to believe.

“…Can I touch it?”

“We’ve already had sex—why ask?”

“…Excuse me, then.”

…Either way, if we’re doing this properly, he needs to be fully hard.

Gently, I take his still-clean cock in my hands.

“…Like this…?”

“Not… bad.”

“…Compared to Hayoon?”

“Yeah.”

“…Hold on.”

This pressure, this speed—is this okay?

Copying what I’ve seen in porn, I stroke him firmly with both hands.

“Hahh…”

“…Pfft. You got hard faster than I expected?”

With every touch, his cock grows harder—strangely satisfying.

Logically, this should be disgusting.

But now it’s just… lewd.

I experimentally flick my tongue against the tip.

…(lick)

…(lick)

Adding just enough pressure to make it twitch slightly.

Working diligently.

“…Hey. …Seo Woojin.”

“What.”

“…Does it feel good?”

“Last time, you told me not to ask you that.”

“…Haaah…”

“Fine. I’ll stop teasing. Stop glaring.”

“…Does it feel good? Just answer.”

“…Not bad. Your hands. And this.”

“…”

Hmph. Spurred by his lukewarm praise,

I take his now fully hardened tip between my lips, (slurp) (lick) sucking aggressively before—

…instead of my sister’s saliva,

my taste,

my scent coats him.

“So to make this feel even better… what should I do…?”

“…Dunno. Try drooling on it more.”

“…? I’ve been doing that the whole—”

“Not like that. Like how you did it before.”

“…”

“…Yeah. Like that.”

Deep enough for the tip to hit my throat. (gag) (choke)

Moving my head back and forth, sucking hard.

…Woojin lets out a pleased sigh before

pushing my head down until I pull off, gasping.

Wiping drool from my chin, I—

“…Hey, Lee Jiyoon.”

“Hah… huh…”

“Hand me a condom.”

“…To use?”

“…”

“…”

His expression says Are you insane?

Yet there’s no real protest in his faint smile.

“…You don’t wanna use one?”

“My period’s about two weeks away, so…”

“Stop phrasing it like I won’t get it.”

“Until all three of us—you, me, and unnie—have sex… It should be safe.”

Unlike unnie,

you can finish

all the way inside me.

“…Then what about the condoms noona gave you?”

“Those, well…”

(click)

Unlike what I’ve heard online,

the rubber smells nothing like fruit as I unroll it—

then lazily drape it over Woojin’s fully erect cock,

…before peeling it off

and tossing it onto his underwear by the pillow.

“…If we do this, save it for later… Would that work…?”

Not a drop of sticky cum inside,

but like a used condom,

one by one,

all three,

…despite having argued with unnie over the number earlier—

the condoms I fought for

are now

just trash,

ruining the thrill of betrayal.
