A few days later, Y/N steps into the kitchen and freezes.
J and Jiheon are already seated at the table, matching smiles painted across their faces. J’s legs are crossed high, her skirt riding up. Jiheon’s leaning forward, elbows on the wood, chin in her palms. They’ve been waiting.
“Morning, oppa,” Jiheon purrs.
Y/N can do nothing but grab a granola bar from the pantry. Don’t make eye contact. Don't make eye contact he keeps telling himself, the granola bar crinkles in his grip.
“You’ve been avoiding us,” J says, her voice a pout. “After everything we shared.”
She lets the last word hang. His jaw tightens.
“I have plans.” Y/N replies
Jiheon laughs, light and sharp. “Plans? With that Ahyeon girl? Please. She doesn’t know you like we do.”
He suddenly turns to face his step-sister “She knows enough. Don't you worry about her.”
J uncrosses her legs, stands, steps closer. Her hand lands on his chest, fingers playing with the collar of his blue shirt. “Does she know how you taste when you’re nervous? How your breath catches right before—”
Y/N steps back. Her hand falls.
“Enough of this. I’m leaving for school.”
And he's out the door before they can respond. The granola bar unopened in his pocket.
The sci-fi club meets every week in room 204, after last period. Poster of a nebula on the door. A dented model starship on the shelf. And Ahyeon, sitting at the back table, flipping through a worn paperback.
She looks up when Y/N walks in. Her hair is pulled back with a clip, loose strands framing her face. The afternoon light catches her cheekbones. She looks absolutely gorgeous.
“You’re early.” she says
He swallows trying to find a little bit of courage, his mouth starts to dry up.
“I need to ask you something.”
She closes the book. Sets it down. Her eyes are dark, patient, curious.
Y/N crosses the room and stops in front of her.
“I really like you Ahyeon-ah. Have liked you for a while. So will you go to prom with me?”
The words come out rougher than he had intended. Unrehearsed. Clearly he didn't think about what he was going to say if she laughed.
She doesn’t laugh.
A small smile spreads across her mouth. She stands. Now we’re close enough that I can smell her shampoo—something floral, clean.
“I’ve been waiting for you to ask,” she says. “Yes, of course i'll go to prom with you, Y/N.”
The air leaves his lungs. Relief. Joy. Something that feels like a punch.
He grins. She laughs. And then she kisses him, right there in the sci-fi club, her lips warm and sure.
The two become the talk of the school by Tuesday.
“You and Ahyeon? Seriously?” My friend Mark claps my shoulder in the hallway. “She’s out of your league, man.”
I don’t argue. She is.
We eat lunch together. She holds my hand under the table, thumb tracing circles on my palm. People stare. I don’t care.
She visits my house after school on Thursday.
The door clicks shut behind her, and I hear footsteps from the living room. J and Jiheon, summoned like bloodhounds.
Ahyeon’s hand is still in mine. I squeeze, a warning.
“So this is where you live,” she says, glancing around. “Cute. Cozy.”
J appears first, leaning against the archway. “Y/N, you didn’t tell us you were having company.”
Jiheon drifts in behind her, arms crossed. “We could’ve helped you prepare.”
The word helped drips with implication.
Ahyeon’s eyes flick between them. She doesn’t flinch.
“I’m sure you could,” she says, her voice sweet and sharp as a blade. “But I think I’ve got handling Y/N down.”
J’s smile tightens. “Oh, do you? He has particular tastes.”
Ahyeon tilts her head. Lets the silence stretch. Then she laughs, light and dismissive.
“Maybe. But I don’t share.”
She turns to me, grabs my wrist, and pulls me toward the stairs. “Your room. Now.”
I follow. Behind me, I hear Jiheon hiss something. J shushes her.
The door clicks shut. Ahyeon pushes me onto the bed, stands over me, her chest rising and falling.
“They’re trying to get under my skin,” she says, but she’s smiling. A dangerous smile.
“They’re jealous.”
“Good.” She climbs onto the bed, straddles my hips. Her skirt rides up. I can feel the heat of her thighs through my jeans.
“I’m going to give you something to remember,” she says, her voice low. “Something they can’t touch.”
Her hands find my belt buckle.
My head tips back as her mouth finds me. She’s slow at first, deliberate—a tease. Her tongue traces a line, circles, retreats. My fingers dig into the sheets.
Then she takes me deeper.
There’s a rhythm she sets, confident, hungry. She knows what she’s doing. Every flick of her tongue, every hollow of her cheek, is a statement.
I’m better. I’m the one.
I can’t help the sound that escapes my throat. A groan, low and ragged.
She pauses. Looks up at me, eyes glinting.
“Let them hear,” she whispers.
Then she resumes, faster now, her hand working in tandem with her mouth. The pleasure builds, tightens, coiling low in my gut.
I grip her hair. She moans around me, the vibration sending a shudder up my spine.
“Ahyeon—I’m close—”
She doubles down. No hesitation. No mercy.
I come with a gasp that turns into a long, shuddering exhalation. My body arches. She doesn’t pull away. Takes everything, holds still as the last pulse fades.
Then she lifts her head.
Her lips are slick. A trail of white runs from the corner of her mouth across her cheek. She doesn’t wipe it.
She smiles up at me, breathless and triumphant.
From somewhere downstairs, I hear a door slam.
They heard.
The house feels heavier after Ahyeon walks out the front door. J and Jiheon waste no time. They corner Y/N in the hallway, bodies pressed close, voices low and sticky with intent.
"She left you all worked up," J murmurs, fingers tracing the line of his shirt collar. "We saw how she looked at you. We can finish what she started."
Jiheon slides a hand down his chest, stopping just above his belt. "We won't stop at a lousy blowjob this time. We'll ride you until you forget her name. Both of us. At the same time."
Y/N steps back, jaw set. "I'm not interested. She's my girlfriend. That's it."
J laughs, but it cracks at the edges. "Come on, oppa. We know what you like. We can do things she never will."
He shakes his head, already turning away. "Nothing you say changes anything. I'm done with this."
They keep pushing for another minute, voices turning sharp, but he keeps walking until the door to his room shuts behind him. Their footsteps fade, leaving only silence.
Prom night arrives like a held breath. Y/N stands in front of the mirror in a fitted black tuxedo, the fabric sharp against his frame. The tie sits straight. His hair is combed back. He looks ready.
J and Jiheon wait in the living room wearing the sluttiest outfits they could assemble. J's top is a tiny black crop that barely covers the underside of her breasts, the fabric stretched thin enough to show the hard points of her nipples. Her shorts ride so high the lower curve of her ass cheeks peeks out with every step. Jiheon's version is even bolder: a sheer white tank top with no bra underneath, the material clinging to every curve, and cutoff denim shorts so short they function more like underwear. Both girls move with deliberate sway, hips rolling as they block the hallway.
"Don't go," J says, voice thick. She steps in close, pressing her chest against his arm. "Stay here. We'll make it worth it. You can fuck us all night. Any position you want."
Jiheon drops to her knees right there on the carpet, looking up with wide eyes. "We can start now. Pull your cock out and let us suck it together. We'll swallow every single drop."
Y/N sidesteps them without a word. He grabs his keys, checks his phone for Ahyeon's text, and heads for the door. Their calls follow him down the driveway, but he doesn't look back.
The prom venue glows under soft lights. Ahyeon waits near the entrance in a flowing red dress that hugs her waist and flares at the hips. When she sees him, her face lights up. They move inside together, hands linked.
They dance slowly to the music, bodies swaying in time. Her head rests on his shoulder. Friends from the sci-fi club wave them over between songs. They laugh, share stories, drink punch that tastes too sweet. The night stretches easy and warm. Y/N forgets everything else while Ahyeon stays close, her fingers tracing lazy patterns on his palm.
Later, Ahyeon pulls him outside and whispers against his ear. "My parents are gone all week. Come home with me."
The drive back to Ahyeon’s house was a blur of electric tension, the air in the car thick with the scent of her perfume and the unspoken promise of what was to come. Every time she shifted in her seat, the red fabric of her dress brushed against Y/N, sending jolts of heat through him. By the time the engine cut out in the driveway, the silence was heavy, charged with a hunger that had been building all night.
The moment the front door clicked shut behind them, the pretense of patience vanished. Ahyeon turned to him, her eyes dark and dilated, shimmering with a predatory kind of desire. Without a word, she reached behind her back, the metallic slide of the zipper echoing in the quiet hallway. The red dress didn't just fall; it cascaded, sliding down the curves of her hips and pooling around her ankles in a shimmering heap of crimson silk.
She stood before him in a matching set of black lace—a bra that struggled to contain her breasts and panties that left very little to the imagination. She stepped into his space, the heat radiating off her skin. Her mouth crashed against his, her tongue sliding deep, tasting of lip gloss and longing. Her hands were frantic, working his jacket off his shoulders and then tearing at his shirt. A button popped, pinging off the wall, as she shoved the fabric aside to feel his bare chest.
Y/N groaned into the kiss, his hands finding the swell of her hips. Below, his cock was a rigid iron bar pressing against the denim of his pants. Ahyeon felt it; she let out a low, humming moan against his lips and reached down, palming him through the fabric. She squeezed him firmly, her fingers tracing the length and girth of him, making him gasp.
As they stumbled toward the bedroom, a sound drifted through the house. It was faint at first—a soft, breathy whimper—but as they entered the room, it became clear. The wall shared a boundary with Asa’s room, and the sounds filtering through were unmistakable.
"Ahh… fuck… right there… oh god…" Asa’s voice was a broken melody of pleasure, echoing through the drywall.
Y/N's dick twitches harder at the sound. He pictures Ahyeon's sister on the other side of the wall, two classmates stripping her down, hands on her tits, mouths on her neck. The image makes his balls tighten.
Ahyeon paused, a playful, wicked smirk crossing her lips. She didn't seem bothered; if anything, the sound of her sister’s ecstasy acted like an aphrodisiac. She pushed Y/N back onto the bed, crawling over him with a slow, sensual grace. She leaned down, her breasts brushing his chest, her nipples stiff and poking through the lace.
"Sounds like Asa is having a very busy night," Ahyeon whispered, her breath hot against his ear. She began to grind her hips against his lap, the friction of the lace against his pants driving him wild. "But I don't want to share. I want you all to myself."
She pushes him backward onto the bed. Her fingers make quick work of his belt. Pants and boxers hit the floor. His cock springs free, thick and veined, already leaking at the tip. She climbs on top, straddling his hips. One hand reaches between them, grips his shaft, and rubs the head along her soaked slit. She sinks down in one slow motion, pussy stretching around him until her ass meets his thighs.
"Ohhh fuck," she moans, voice loud and clear. "Your cock feels so good inside me."
She began to bounce, her tits jiggling violently in the lace bra. Hips roll in steady circles, then lift and drop. Each descent takes him deeper. Wet sounds fill the room as her pussy grips and slides along his length. "Ahh… ahh… yes… deeper… fuck me harder…", rhythm slow at first but as the sounds from the next room intensified, so did her pace.
Through the wall, Asa’s moans grew frantic, bordering on screams. "Yes! Fuck my pussy! Harder! Oh god, your cock is so big! I can't—ahh! Right there!"
The sound of Asa's pleasure pushed Ahyeon over the edge. She reached back, unhooking her bra with a quick snap and tossing it across the room. Her bare breasts swayed as she slammed her hips down harder, her pussy gripping Y/N with every descent.
Y/N grips her hips, thrusting up to meet her. His cock drives into her soaked heat again and again. The head nudges her cervix with every deep stroke. "Fuck, Ahyeon… your pussy is squeezing me so tight."
Ahyeon let out a loud, piercing moan, her eyes rolling back. "Ahhh! Yes! Right there! Pound my cunt! Make me scream louder than my sister!"
Next door, the audio shifted. The sounds of shifting bodies and heavy breathing indicated a change in position. Asa was now riding one classmate while a second pushed into her from behind. Her voice cracked, a mixture of shock and pure bliss.
"Ohhh shit! Both holes! You're stretching my ass so wide! Fuck me! Fuck me!"
The double penetration makes her scream. The classmate under her thrusts up into her pussy while the one behind grips her waist and drives into her ass. Skin slaps against skin. Wet squelching noises mix with her cries. "Ahhh! I'm so full! Don't stop! Cum inside me!"
Ahyeon hears every word. She rides Y/N even harder, ass slapping against his thighs. Her pussy clenches and flutters around his thick cock. "Listen to her getting double-teamed. Two cocks ruining her at once. But you're mine. This dick belongs to me."
She grinds down in tight circles, clit rubbing against his pubic bone. "Ahh… ahh… I'm getting close… your big cock is hitting so deep… fuck… fuck…"
Y/N's hands slide up to squeeze her tits. He pinches her nipples, rolling them between his fingers. She moans louder. "Yes! Play with my tits while you fuck me!"
The race intensifies. Ahyeon slams down with everything she has, pussy dripping down his shaft and onto his balls. Each thrust makes obscene wet sounds. "Ahhh! Yes! Fuck! I'm gonna cum! Cum with me!"
Next door, Asa is losing it. "Oh my god! I'm cumming! Both cocks are making me cum so hard! Ahhh! Fill my holes!"
Her screams peak, raw and desperate. The two classmates grunt and thrust harder, one flooding her pussy while the other pumps cum into her ass. Asa shakes between them, voice hoarse. "Yes! Yes! So much cum!"
Ahyeon hears her sister's orgasm and it pushes her over. She rides Y/N at a frantic pace, hips snapping. "Ahhh! I'm cumming! Your cock is making me cum!"
Her pussy spasms around him, walls pulsing and milking. Y/N groans, hips jerking up as he erupts inside her. Thick ropes of cum shoot deep, filling her until it leaks out around his shaft with every bounce. "Fuck… Ahyeon…"
She keeps moving through both their orgasms, slower now but still grinding, drawing every drop. "Mmm… so much cum… I can feel it pumping into me."
They stay locked together, breathing hard. Through the wall, Asa's moans soften into satisfied whimpers as the three of them collapse. Ahyeon leans down, kisses Y/N slow and deep, then whispers against his lips. "Best night ever."
Y/N holds her close, cock still twitching inside her soaked pussy. The sounds from next door fade, but the memory lingers, making the afterglow even sweeter. He strokes her back, content, completely hers.
Later that night as Y/N arrived home after giving his girlfriend a couple more orgasms, his relentless step-sisters were waiting for him by the kitchen table.
"So, how was she, Y/N?" Jiheon asks
"Was it everything you hoped for?" J sarcastically adds
"I'm not talking about this with my sisters. Plus it's none of your business. You should worry about your own boyfriend, Jiheon-ah." he says with a smirk knowingly
"What's that supposed to mean? she asks
"Oh, i don't know. Maybe the fact that i haven't seen him around in over a month." I'm sure you did something to upset him. Or did he think you were a bad fuck and left you for someone better?"
"What the fuck did you just say to me? Last week you were begging me to swallow your cum, now you've got a girlfriend and you suddenly think you're above it all?" Jiheon replies furiously as she gets up from the table, almost screaming at Y/N
"Maybe i did. Or maybe i just got tired of letting you two play games with me. All of this teasing and flirting after making fun of me for years for liking your older members. And now you're trying to fuck up the best thing that's ever happened to me." "If you care about me, then just stay the fuck out of my life." Y/N says as he walks out of the kitchen and up the stairs, slamming the door to his room.
"Looks like little bro finally grew some balls." J says "What are we gonna do about this? We can't just let him walk away after everything that happened."
"Oh, he's not walking away i can promise you that. And since we can't just threaten to expose him to that slut girlfriend of his, we'll have to make it impossible for him to resist us." Jiheon replies
