.

Moonlight is brighter than I expected.

…I thought I’d have to wait until my eyes adjusted to the darkness.

“Let’s wrap this up and get out of here. They said the inner doors would open, but they asked us to check in before leaving.”

“Take it easy. Just take it easy. …As long as we keep the noise down, right?”

“…You’re way too relaxed.”

“Earlier, it looked like no one was around, so… Oh, wanna sit here first?”

Lee Hayoon’s expression, reluctant to lose to her younger sister and hesitantly following along.

Lee Jiyoon’s expression, eager to outdo her older sister and already kneeling on the floor by the bed.

I never thought they’d be this obvious.

Thanks to that, I didn’t expect…

…the blood to rush downward so quickly.

Didn’t even cross my mind.

“Huh? I only said to sit, not to unbuckle your belt~”

“We’re gonna take it off soon anyway.”

“Hmm? Were you really just planning to strip, fuck, cum, and leave?”

“…Is there anything else to do?”

“Of course, that’s all we’re doing, but let’s not rush it. There’s something called ‘mood,’ you know? For example…”

Even with the blinds drawn to block outside view, the faint moonlight spills inside.

The hand reaching for the belt is caught by Jiyoon’s hands, stopping awkwardly mid-motion before being pulled elsewhere without hesitation.

At first, I thought it was Jiyoon’s lower stomach—but no.

A little higher.

Then, her chest—but no.

Even higher.

Her face, wearing a faint, amused smile.

Higher still.

“Can you stroke me gently first? ……Make me feel like I want to be taken even more than my sister?”

Pulling my hand up to her moonlight-colored hair.

Dragging it there, then pressing close so Hayoon can’t easily cut in.

Not that it matters—the side is wide open, so all she’s done is occupy my immediate view.

“You’re the one who always thinks like that, so of course you’d cut in between me and her.”

“Pfft… True, huh? Well, if you’re jealous, maybe you should’ve treated me better from the start.”

“…….”

“A man I want to sleep with every night, a man I’d love to fall asleep in the arms of—the kind of fantasy I indulge in daily. …A man I picture in my head when I touch myself. You’re the first one like that in my life.”

“Hey, Jiyoon. Even so, he’s still your sister’s boyfriend…”

While Jiyoon monopolizes me, Hayoon grumbles and wriggles closer from the side.

When I pull her into a tight hug with my free arm, her whimpers vanish instantly.

…But the way she keeps glancing up at me makes it impossible not to know what she wants.

In the end, the scales tip slightly—toward the one right in front of me.

After a deep breath, I start stroking Jiyoon’s hair, my wrist still in her grip.

Why?

Well.

Because that Jiyoon—

A witch who’s never once been seen smiling—

Only in front of me does she let her guard down, as if thoroughly tamed.

“More. Keep stroking.”

“…How much more?”

“Hmm~… Until my sister, who’s gone quiet in your arms, starts getting jealous of me again?”

“…! Hey, wait. Why call it jeal—… Mmph, mmm…”

Honestly, it wouldn’t be strange if Hayoon blew up in anger right now.

Even as her younger sister openly commits adultery with her boyfriend, she just melts when hugged.

Even if I keep stroking Jiyoon, Hayoon eagerly kisses me first, tangling her tongue with mine.

This situation fits perfectly into the secret private life I’ve always imagined.

“Mmpph…, mmm, mwah… …Haaah……”

“…Wait, that’s the opposite of what I said. …I told you my sister should be jealous of me?”

No one else—no ordinary person—could ever know about these sisters’ private lives.

“…Hey. You pervert. If you kiss my sister like that and get hard, what does that make me?”

“…, ……Mwah… Mmm…”

“Am I just a sticky onahole you use when my sister needs a break? …Well, not that I hate it…”

“Nn, mmph… ……. ……Nngh…”

Only.

Only I, as a man, can monopolize this scene.

And enjoy it.

“Hey…, …it keeps touching my stomach. This disgusting thing.”

“Haaah… Ah… Woojin, ah…”

“…Hurry up and do something about it. Like… stuffing it deep into that onahole to solve it… …Ah…”

…Jiyoon, waiting with her tongue slightly out.

And sharing a kiss full of Hayoon’s taste.

It’s all unavoidable.

A fleeting question slips into the deepest part of my brain.

I shove it into a corner where I won’t pay it any mind.

“Sis, you’re licking there…”

“Be careful not to let your tongue touch…”

“…….”

The music from the venue sounds louder than I thought.

…Must just be the volume.

Even when I heard it live, it was loud enough to make my heart pound like in a concert hall.

Leaving behind only that careless judgment.

…What the hell am I even listening to right now?

“Mwah…, mmph…, haah……”

“….”

So, I get that they’re going to have sex here.

I get that they want Seo Woojin to remember today’s scene while he works.

But didn’t something that shouldn’t have been said slip in?

It’s not just about leaving behind memories of sex with Hayoon.

…That younger sister, too.

He said he’d leave memories of sex with Jiyoon as well.

To be precise…

Memories of thoroughly devouring both Jiyoon and Hayoon.

That’s what he said.

“Hey…, move aside for a sec, sis. …How long are you gonna keep sucking by yourself? I’ve been stuck awkwardly licking the base this whole time.”

“Mmmph…, but… It’s been twitching nonstop since earlier…”

“‘Earlier’ was already three minutes ago. Guess your mouth just feels too good in a weird way, so I’ll take over now.”

“W-wait… I was here first…”

“I’ll teach you how to do it properly later… Just a sec?”

“Hey, even so…”

“You can lick the base for me instead… …Hahh……”

Against the outer wall of the building right next to the infirmary window.

Crouched there, clinging to the wall, I cover my mouth with my hand and strain to catch every sound leaking through the window gap.

It’s a relief no passersby are around, but the conversation inside is so beyond common sense that my head is in utter chaos.

No, “chaos” might not be the right word.

I’d somewhat expected this from the start, and as much as I didn’t want to believe it, it turned out to be true.

To rephrase, my head is filled with disgust—that’s the perfect way to describe it.

Especially since it’s not just two girls fooling around.

It’s sisters… doing that.

Of course, I’d still dislike it even if it were just two girls, but…

…Hearing that just shattered my sense of normalcy.

It’s like when you see something so revolting that you build a tolerance, and other things don’t seem as bad.

If that’s the case, maybe Hayoon, whom I met downtown, really was carrying a vibrator or something.

After the three of them took a taxi back home…

They might’ve done something similar to what’s happening now.

Frowning as the puzzle pieces fall into place, another voice drifts out from inside.

“…Ha, shit…”

“Cough, …cough, hack! Nngh…, mmm…”

…Seo Woojin’s voice, a quiet curse.

And Jiyoon’s voice, coughing like something’s stuck in her throat.

Even without seeing it, I can guess exactly what happened.

If he came straight into her mouth, that’s the sound she’d make.

Ugh…, damn, seriously…

I thought stuff like that only happened in porn, just for show.

But girls… no, women actually suggest doing it themselves sometimes?

Well, the guy gets to enjoy the service, so of course he wouldn’t refuse…

Maybe this is just normal foreplay for couples.

But for me, that kind of thing…

Feels physiologically impossible.

It’s just… filthy.

Licking and sucking that? Why would anyone do it?

Even the reverse—a guy doing it to a girl…

…I really don’t get it.

“…? What? How much did you even shoot for it to drip down this much…”

“…Hahh…, well, I couldn’t swallow because I sneezed…”

“Sneezed…? This looks more like you spat half of it out…”

“Sp-spit? I’ve never done that…”

Trying—and failing—to understand why anyone would do such things.

Hiding here, eavesdropping, forces my brain to imagine it anyway.

Seo Woojin, lounging on the bed, enjoying himself.

Jiyoon, coughing and sneezing, letting cum drip down.

Hayoon, startled by the sheer volume while teasing the base beside her sister.

But that’s not all.

Between the vivid images of their faces… something unfamiliar lingers.

…His cock.

Hard and erect, ready to release.

Seo Woojin’s cock is—

“Hurry up and clean it. I’ll help…”

“…I’m trying. It’s just… really big.”

“…….”

Since Hayoon drunkenly mentioned something weird last time…

I’ll account for that.

A little bigger.

Like in porn…

About that size.

Length-wise,

15cm? …16cm?

…Anyway,

That’s already huge.

Unconsciously comparing it to my boyfriend’s.

Much bigger.

Much thicker.

Honestly, when Hayoon hesitantly spread her hands to describe the size… it was monstrous.

Bigger than a handspan.

I doubt it could even fit.

Even if it did, would it feel good…?

Seems like it’d just hurt like hell…

I’m fine with just fingers, so something smaller would be…

“Hey……. …Shall we start?”

“…….”

But mid-thought—

From beyond the window.

Not my girlfriend Hayoon’s voice.

But a girl who just turned 20,

Until recently a high schooler.

Her voice, dripping with arousal,

Hits my ears crystal clear.

“…Let me go first this time…”

“…….”

The voice of Hayoon—who usually just sips apple juice and smiles cutely—

Indistinguishable from her sister’s.

Because it’s the first time I’ve heard it like this.

“You went first last time, sis. …That day you met your friend.”

“But you’re the one who lent Woojin to me in the first place…”

“…….”

The scene, from Seo Woojin’s perspective,

Morphs into the kind of setup often seen in porn.

My brain rebelliously reconstructs the fantasy.

“…Oh, right. How many guy friends do you have, sis? I don’t have any.”

“W-why bring that up now…”

“You’ve always had a lot of guys around you.”

“…They’re all just friends, no interest either way… And after I made our relationship public, nothing’s happened…”

Anyone could see she’s just horny and pushing.

Crushing those boys’ feelings without a second thought.

The sound of shoes dropping to the floor becomes

Jiyoon and Hayoon climbing onto the bed.

“I get your point, but I prefer noona’s side more. …Your friends have no idea about this side of you.”

“…Ah, right. This girl’s a total pervert…”

“T-this side…?”

“You know it too, noona. …Having sex all night with your little sister isn’t exactly normal.”

“…….”

The rustling of bedsheets, the faint creaking, becomes

The three of them on the bed, adjusting into position.

A position where all three can tangle together

Without issue.

“…Wait. Lee Jiyoon.”

“…….”

The sound of fabric roughly brushing against skin,

Or Seo Woojin clearly calling Jiyoon’s name—

…Becomes exactly that.

“Hey, that tickles…”

“…How long have you been like this?”

“Since… after class. In the bathroom. On the lowest setting… Turning it on and off…”

The buzzing sound accompanying her giggles—

The sex toy I’d only suspected without proof—

Becomes Jiyoon playfully pressing it against her thigh.

“That… When you met that pretty senior, sis…, you started already soaked thanks to this…”

“…….”

“…I could just pull my panties aside and let him pound me hard like last time…, no problem…”

Jiyoon’s hand sliding under her ass,

Pulling the pale skin near her pussy,

Exposing the glistening pink flesh, soaked with arousal,

To her sister’s boyfriend—

…I can’t stop the runaway fantasies.

“…….”

Today, for some reason, I feel… strange.

“…Ah, Seo Woojin… Wait……”

“…….”

Even though I’ve already learned all three of their secrets, it feels like there’s more to hear.

The reason I’m crouched here, back against the building’s outer wall.

No matter how hard I try to think rationally,

Only one strange reason comes to mind.

…I can’t help it.

All I can call it is this strange feeling.
