.

The darker the surroundings, the more you can see the faintly glowing stars.

The quieter the surroundings, the easier it is to pick up the subtlest of sounds.

“…”

In the small room where I now had the bed all to myself—unlike just moments ago—the distant sound of my sister’s voice reached me.

“Kyaaah~ Youth… Ah, youth.”

I had expected this much.

Lying there in Seo Woojin’s borrowed shirt, I hugged the blanket with a satisfied smile.

Unnie… You’re just making all that noise on purpose because you’re jealous. It’s so obvious.

After the way she looked at me in the living room earlier, only an idiot wouldn’t notice. An idiot.

But you know what?

Her acting all possessive after Woojin and I just had sex?

It’s like a cute little puppy barking its head off, thinking it’s being intimidating.

Like, for example—

“Master~ You can’t go over there. She’s a bad girl.”

That kind of vibe?

“Heh…”

Next, I’ll probably hear her sweet little moans.

If it’s already this loud, I wonder how the neighbors will look at us tomorrow.

Lying on the bed, I half-listened while entertaining idle thoughts. The door, of course, was left wide open.

What if—

After overhearing how Unnie and Woojin are going at it, I do the exact same things to him tomorrow?

What if I make him feel even better than she did?

How would they react?

Woojin? Well, he’s already a guy who looks fine on the outside but is a little rotten inside—just like me. He’d love it.

But Unnie, the pure romantic?

Would she puff up her cheeks and pout?

“…I wanna see Unnie’s face…”

As the peaceful silence stretched on, my sense of wicked amusement only grew.

Then, from beyond the wall, Unnie’s voice reached me again—”No, no…”—resisting.

…Pfft. Hilarious.

What do you mean, no?

You’re just putting on a show before giving in anyway.

Is this some kind of roleplay?

Unnie in a school uniform getting ravaged by delinquent Woojin?

I get that you want your boyfriend’s attention, but this script is adorable.

Laughing quietly to myself, I barely had time to mock her before another sound came from the other room.

—”H-Hyuk…?!”

Hyuk.

A voice that sounded like it had slipped out despite her best efforts.

Very Unnie-like, if I had to describe it.

A moan that was more cute than vulgar.

Would it be better if I moaned like that too?

Or should I just not overthink it and let it come naturally?

As I blankly pondered Woojin’s preferences, a few more similar moans reached me before another sound hit my ears.

“…”

Thud. Thud. Thud.

Exactly three times.

But it wasn’t just the sound of fucking.

…It was bigger than I expected.

Much bigger than what I’d heard from my own room.

The sound of two bodies slamming together violently.

“…”

…Well. I did expect something like this.

She lent her boyfriend to her little sister—you really think she’d just satisfy her urges lightly and call it a day?

Besides, the sex I overheard through the phone sounded… pretty intense, didn’t it?

…So.

Yeah.

“More intense than expected.”

That’s the best way to put it.

“…”

Holding my breath, I listened as the sounds, which had paused briefly, started up again.

…And of course, my mind began painting its own vivid picture.

Unnie, pinned beneath Woojin’s grip on her hips, reduced to nothing but a hole as he pounds into her relentlessly.

Unnie, grinning dopily like she’s loving every second of it.

Woojin, looking down at her with satisfaction.

…And finally, the cock I had just been sucking on earlier—

Now soaked in Unnie’s slick juices.

All of it.

“…”

Maybe it was because that mental image bothered me a little.

Just a moment ago, I was perfectly content lying here, relaxing while listening to Unnie’s desperate noises like they were background music.

…But the more I listened, the more my thoughts shifted.

Why should I hold back?

Just because Woojin told me to stay in my room and play games without interrupting…

Do I have to obediently listen?

…We’re not in some master-servant relationship.

What if I don’t want to?

What if I want to laugh at Unnie…

For being such a pathetic loser who can’t even keep her boyfriend in check?

“Heh.”

With that thought, I tugged at the loose hem of the shirt and got up.

Then, muffling my footsteps as much as possible, I stepped over the protruding doorframe and—

Like a cat, crept silently straight to Unnie’s room.

The closer I got, the more sounds that hadn’t reached me before began to filter in.

—”I’m… I’m coming……♡” —”So?” —”I-It’s just…” —”Hah… …Lift your ass more. Hurry.” —”…Nn, I really don’t… Hyuk…?! Hahh……”

Amidst labored breathing and fragmented conversation, the relentless thud-thud-thud of flesh against flesh.

The heavy creaking of the bed under their weight.

And moans—

…More vulgar than before.

The kind a bitch in heat would make.

The living room, usually so quiet, was now thick with those sticky, obscene sounds.

And I—

“…”

—swallowed nervously, then carefully reached out.

Making sure the click of the handle was silent, I turned it slowly.

…Pulled.

The moment the door opened, the thick, lewd scent hit me like a physical force.

And I stepped—

Inside.

—”S-Seonbae……, …stop, no more… Hih…?!?” —”Hah…” “…”

Immediately to my right.

…Woojin’s sweat-drenched back. I walked toward him.

The sound of his firm lower abdomen slamming into Unnie’s ass.

The wet, sticky squelch of her arousal—inaudible until now—filling my ears.

…Still unaware of my presence,

one hand gripping Unnie’s jet-black hair tightly,

Woojin fucked her like an animal—

Thud-thud-thud.

I crept closer.

Closer.

…Then reached out.

And with my fingertips—

Tap. Tap.

—touched his sharp hip bones.

“…”

He jolted in surprise, and I grinned up at him, lips curling.

“…”

—”Don’t mind me.” —”Keep going.”

…You’re insane too, Lee Jiyoon.

I knew you were a little unhinged when I saw your true nature, but I didn’t expect this much.

I might have to reevaluate my assessment of Lee Jiyoon.

She’s even more of a psycho than I am.

“…Nn, puh……”

Playing along with this madwoman, I let go of Lee Hayoon’s ponytail—which I’d been pulling until now—

and, opposite of before, pressed down firmly on her erector spinae, near her shoulder blades, as I continued thrusting.

Better to deal with Hayoon’s gaze first.

Once she gets used to situations like this, it’ll be different,

but right now, if she sees Jiyoon, she’ll obviously start growling. How am I supposed to show her like this?

“Hngk…, Seonbae, just a second… Let me rest…” “…Not until I cum once.” “I’ve already… three times… Hihh…, f-four…” “Hayoon-ah.” “Y-Yes…” “I don’t really care how many times you’ve cum. …Lift your hips more.” “So mean…” “Hurry.”

As Hayoon buried her face in the pillow and moaned, Lee Jiyoon began cautiously moving around the room.

If Hayoon senses her, she’ll kill her.

Is she not thinking?

Or is she so consumed by wicked amusement that she’s willing to take that risk?

“…”

Even as I thought she’d lost her mind,

my left hand—no longer on Hayoon’s waist—

twitched toward Jiyoon, who was only wearing my shirt.

—”Why?”

Jiyoon, asking even though she already knew.

Jiyoon, pretending innocence even though she came here for this.

As she drew near, almost climbing onto the bed, her jade-green eyes glinting mischievously,

I—

Yank.

—grabbed the shirt she was wearing and pulled her close.

“……, …Chup.”

While Hayoon trembled through another orgasm, oblivious,

I kissed her little sister.

Our front teeth clacked awkwardly.

Our tongues, overexcited, slid messily against each other.

…A complete mess.

“…Hih…, Pull out… Seonbae…” “…Hah… Huh…”

Hayoon, still deep in her roleplay.

Far from slowing down,

I fucked her—

Harder.

Much harder.

…With enough force to crush her womb,

I hammered into that deepest, most secret place.

Thud-thud-thud.

Even as Hayoon’s ass jerked with each thrust,

even as she begged incoherently, not even knowing why anymore,

even as she came with lewd moans I’d never heard before—

I ignored it all.

The wet, filthy sounds never stopped.

I kept going.

“If you go that deep… I said no…” “…”

With one hand, I patted Hayoon’s heaving waist reassuringly.

With the other, I pulled Jiyoon’s head closer.

The sound of flesh slamming together grew louder,

…until Hayoon’s soft ass lost its shape entirely,

and I shoved my fully erect cock as deep as it would go.

“Seonbae, I… I won’t report you to the police…” “……. Hah…” “Hahh… …Ha…” “Just this much……, ah, nghhk…?! Nn, ughk……♡”

About a minute later.

After a long, breathless kiss, Jiyoon’s lips parted with a tiny sound—like she couldn’t care less about hiding.

I immediately muffled it by slamming into Hayoon harder—thud, thud—no mercy.

Then, as Jiyoon giggled and slid down, my gaze followed.

“Nn, kuhk…. Seonbae’s… Seonbae’s cock, amazing…” “…”

…My collarbone.

My chest.

Every sweaty, filthy part of me—

She licked and marked them all,

right under her sister’s nose.

How could I not look?

Fuck.

“Ah, Seonbae, Seonbae… My hair, don’t pull… don’t pull it…”

Jiyoon, completely unrepentant, clung to me and lapped at my chest.

Instead of meeting her gaze, I grabbed Hayoon’s hair again and shoved my cock to the hilt.

First reason? I didn’t like Jiyoon’s teasing expression.

…Second? Getting caught was inevitable anyway.

If that’s the case,

it’s better if Hayoon’s too lost in pleasure to process it properly.

But unfortunately—

“Nngh—! I’m… I’m cumming… Being… forced by Seonbae…”

Hayoon just gripped the bed tighter, moaning like a bitch in heat every time I bottomed out.

Holding her ponytail tightly, I aimed for her most sensitive spot—deeper than her cervix—and wrecked it.

Sweat dripped onto the sheets.

Hayoon, who had been calling me Seonbae so properly, was now reduced to nothing but lewd moans.

…Meanwhile, Jiyoon—who had been licking me just moments ago—grinned,

then slowly lowered herself.

Tap. Tap.

She opened her mouth—ah—

and brought her index finger to her lips.

“…Fuck. Seriously… Hah…”

My sanity snapped.

Shattered.

I fucked Hayoon relentlessly until I was on the verge of cumming,

then—while she lay there, gasping, the bed soaked beneath her—

“……. ….”

—I grabbed Jiyoon’s head,

forced her mouth open like a toilet,

and—

Splurt.

Splurt.

Splurt.

—emptied every last drop of cum that should’ve been in the condom

straight into her little sister’s mouth.

…Even as it spilled past her lips, unable to swallow it all,

I didn’t care.

Splurt.

Splurt.

I drained everything—

like squeezing out the last of a spent pouch.

“…”

…Then.

Jiyoon.

“Hahh… Ha… Hah…”

Gulp, gulp.

Rolling the cum in her mouth,

she—

Ptooey.

—spat it onto her sister’s trembling ass,

as if I had creampied her there,

then smiled sweetly and left the room.

—”See you tomorrow.”

That was all she said.

A loaded farewell.
