You and your best friend Star always had some tension. The kind that lingered in the air like a spark just waiting for the right moment to catch fire. You both came out to each other as bi around the same time, some random late-night conversation that spiraled into vulnerability, confessions, soft laughs that held more weight than either of you admitted.
Ever since then, things were never quite the same.
Even when you started dating your amazing boyfriend, Heeseung, that tension with Star never faded. If anything, it got worse. More noticeable. More dangerous.
And Heeseung knew. Of course he did. It was impossible not to see.
The stolen glances. The subtle brushes of your fingers as you passed each other something. The way she’d look at your lips mid conversation like she was imagining how they’d taste. Like there was a secret buzzing underneath everything, one that he wasn’t fully a part of.
And fuck—he’d be lying if he said it didn’t make his cock hard beyond belief.
He tried so hard to convince himself it was wrong. That his girlfriend couldn’t possibly be messing around behind his back. That even if something was happening, it couldn’t be real.
But deep down, some dark, needy part of him didn’t just notice.
He wanted to see it.
⸻
One night, you all went out together.
It wasn’t anything fancy—just drinks, music, and too much teasing in a tight booth, but you’d dressed up anyway. You wore that dress that barely covered your thighs, the one that clung to your waist and rode up every time you shifted in your seat. Star showed up in something even more dangerous—low cut and backless, hugging her curves, practically made to draw eyes. And it did.
Heeseung couldn’t stop looking at the two of you. Legs brushing under the table. Lip gloss shining under the dim bar lights. And those laughs—those goddamn breathy, tipsy laughs that made him twitch in his jeans.
Before long, shots were being passed around like candy.
You were a few drinks in, warm and giggly, leaning on Star more than you needed to. She rested her hand casually on your thigh and you didn’t stop her.
You leaned in to whisper something to her—something stupid, probably, but the second your lips got close, you both froze.
Her eyes flicked down to your mouth.
Yours did the same.
And you didn’t know who leaned in first. Maybe it didn’t matter. A second later, your lips met.
Soft. Careless. Just a brush at first. Then a little more pressure. Just enough for your lips to part slightly, enough for it to feel real.
Hee saw the whole thing. Watched you kiss her right in front of him like it was the most natural thing in the world. Like you’d done it a hundred times.
And fuck—his cock throbbed. He shifted in his seat, trying to hide it, trying to keep breathing like this wasn’t the hottest thing he’d ever witnessed.
You and Star pulled away a second later, giggling like nothing happened.
“Girls will be girls,” he told himself. “It’s nothing.”
But he couldn’t get the image out of his head.
⸻
The next time it happened, it wasn’t in public.
It was late. Just a girls’ night.
You and Star curled up in your bed, oversized shirts and underwear, fresh-faced from cleansing and already halfway through a bottle of wine. Your legs tangled as you lounged across the blankets, faces flushed and limbs loose with that familiar wine buzz.
There was music playing low—something soft, something sensual—and the air between you was thick.
You laughed at something dumb she said, your head falling into her lap. Her hand came up to brush your hair back from your face. Slow. Lingering.
“You’re so beautiful,” she murmured, voice low and sincere, fingers still stroking through your hair.
You blinked up at her, heart racing. “What?”
She smiled. “I said you’re pretty.”
There was a pause.
And then that same tension hit again—like déjà vu. Your faces were close. Your eyes locked.
One of you moved. You weren’t sure who.
But this time, the kiss didn’t stop after a second.
It deepened. Turned hungry. Tongues sliding. Teeth clashing softly. Her fingers gripping your jaw as she tilted your head just right.
You pulled back, breathless. “We shouldn’t…”
But she was already kissing down your neck, her hand slipping beneath your shirt, cupping your breast.
You moaned softly, your thighs pressing together.
And then her fingers were in your panties, slipping between your folds, rubbing slow circles over your clit before sliding in—two at once. Her ring and middle finger, curling perfectly inside you as you arched against her.
She fucked you like she knew exactly where every nerve lived. Wrist-deep. Palm flush against your pussy. You came hard, thighs trembling, her lips at your neck whispering filth.
You swore to each other the next morning it was accidental.
But it kept happening.
⸻
Little kisses. Lingering makeouts that left you breathless and needy. Her fingers sliding under your skirt at dinner parties when no one was looking, fucking you slowly with a smirk on her lips. You’d bite your lip to hold in your moans while people chatted just feet away.
Heeseung always pretended not to see.
Pretended he didn’t notice the way your lips were swollen when you got home. Pretended he didn’t see the bite marks under your shirt or the way your thighs trembled when you walked.
But every night, he’d fuck you harder than ever, gripping your hips like he was trying to brand you. Whispering in your ear, “Is this what you need? Or do I need to bring her in next time, huh?”
And you’d moan, because you couldn’t answer honestly. Because the thought of both of them wrecking you at once made your head spin.
⸻
Then came the party.
You were there with Hee, drink in hand, his arm slung around your waist protectively.
You’d only had a couple drinks, but your body was already loose, warm, floaty. You turned to say hi to someone and bumped into her.
Star.
She looked good. Unfairly good. Her eyes lit up when she saw you, and before you could even speak, her hand slid into yours, tugging you away from the crowd.
You didn’t resist.
She led you down a hallway, past a dozen closed doors, and slipped into a guest room tucked at the end. The second the door closed, she shoved you up against it, lips crashing into yours.
You moaned into her mouth as she kissed you hard. Sloppy. Desperate. Her hands roamed everywhere—your waist, your thighs, your tits, gripping you like she hadn’t touched you in weeks.
By the time she pushed you back on the bed, your lips were red and swollen, panties soaked through.
That’s how you found yourself in this position.
Her tongue buried between your thighs, suckling your clit like she was trying to drink your soul out of you. Her hands gripping your thighs, holding you in place as your hips rolled against her mouth.
And you?
Your tongue was flat against her pussy, her taste smeared all over your lips. You licked into her heat, slow and deep, moaning as her thighs trembled around your face.
Sixty-nining with your best friend in a stranger’s guest bed. Half the party just down the hall.
Your moans vibrated into her, your tongue gliding through her folds, dipping into her slick heat before flattening again, drinking her in like water.
The air was thick—hot, sweaty, desperate. The bed creaked with every grind of hips and press of fingers. You could barely think straight. Just the taste of her. The way she whimpered. The pulsing ache between your thighs she never gave you time to recover from.
You didn’t even hear the door creak open.
But Heeseung did.
He stood in the doorway, frozen.
His eyes dragged over the scene—the arch of your back, the way Star was moaning into your cunt, the pure filth of you both, completely absorbed in each other.
His breath caught in his throat.
You pulled back from Star just enough to pant, your lips glistening, voice wrecked. “Hee—”
Your voice died the second your eyes met his.
He didn’t speak.
Didn’t blink.
His jaw was clenched. His hand twitched by his side like he didn’t know whether to leave, to speak—
Or to start touching himself.
Star didn’t even stop.
She looked up at him from between your thighs, lips still wrapped around your clit. She smirked, licking a slow, deliberate stripe up your slit before whispering against it, “Are you just gonna stand there…”
She paused.
Sucked your clit into her mouth hard.
You cried out.
“…or are you gonna help?”
That snapped him.
In seconds, Heeseung was across the room, door shutting behind him with a soft click. His eyes never left you. Not once. His movements were slow, calculated. Like a wolf circling prey he’d been stalking for weeks.
He peeled his shirt off first, tossing it carelessly to the floor. Then his belt. Then his jeans. His cock strained against his boxers, thick and hard and already leaking.
“I knew it,” he muttered under his breath, voice low, gravelly. “Knew you two were doing shit behind my back.”
You sat up a little, breathless, still pinned under Star. “I—I wanted to tell you—”
“Shh.” He leaned down, capturing your lips in a slow, filthy kiss. His hand tangled in your hair, holding you still as he devoured your mouth, tongue deep and possessive. “You think I didn’t see the way she looks at you? The way you look back?”
He broke the kiss with a low growl, eyes dark.
“You think I didn’t notice the marks? The way your thighs shake when you come home?”
You whimpered, hips grinding into Star’s mouth again on instinct. She moaned against you, still licking, completely content to keep you open and needy for him.
Heeseung’s eyes flicked down to the sight of Star still between your legs, tongue moving in slow, wet circles. His cock throbbed.
“Fuck,” he breathed. “You’re such a slut for her, aren’t you?”
You didn’t answer.
Didn’t need to.
Your body said it all—arched, trembling, mouth parted in desperate moans. You looked ruined. And he hadn’t even touched you yet.
He shoved his boxers down, letting his cock spring free. He wrapped a hand around it, pumping slow as he knelt behind you on the bed.
“Let me see that pretty mouth,” he said, guiding his tip to your lips.
You moaned and opened instantly, letting him slip in, warm and heavy on your tongue.
You were being devoured and fed at the same time—Star sucking and licking your cunt like she owned it, Heeseung fucking your mouth slow, low groans rumbling in his chest every time your tongue swirled around his tip.
You were shaking between them, the filth of it all making your brain foggy. The taste of him. The taste of her. The hands in your hair. The wet, obscene sounds of your soaked pussy and your greedy mouth.
Your jaw was slack, lips stretched around Heeseung’s cock as he fucked into your mouth in slow, shallow thrusts—just enough to tease, to taste, to claim.
His hand stayed tangled in your hair, guiding your head gently. But his voice?
His voice was pure control.
“You like this?” he rasped, hips rolling forward, cock hitting the back of your tongue. “Getting fucked in your mouth while she eats your pussy?”
You tried to nod, but Star moaned against your clit, her tongue flicking fast and relentless, and your eyes rolled back.
“Fuck,” Heeseung groaned, pulling out with a wet pop, smearing the tip across your spit-slick lips. “You look so pretty like this. All messy and used.”
You gasped for breath, drool running down your chin, pussy throbbing as Star buried her tongue deep inside you again.
“She tastes so fucking good,” Star purred against your cunt, her voice soaked in hunger. “You’ve been missing out, Hee.”
Heeseung let out a breathless laugh. “Trust me, I’m about to catch up.”
His hands gripped your hips, dragging you up off Star’s face. You whimpered at the loss, your pussy clenching around nothing, aching to be filled again.
“Lay back,” he ordered, voice low, cock heavy in his hand.
You obeyed, your body pliant, dizzy from pleasure. Star slid up beside you, lips glistening with your slick, licking her fingers clean like she was savoring every drop.
Heeseung leaned over you, cock in one hand, the other bracing himself beside your head. He kissed you—deep, messy, tasting Star on your tongue—and lined up with your entrance.
You were soaked. Ruined. Practically dripping down your thighs.
“Fuck, you’re tight,” he hissed as he slid in, inch by inch, until he was buried to the hilt.
You cried out, back arching, hands gripping the sheets.
Star leaned over, kissing your neck, trailing her tongue up to your ear. “You look so hot when you take him,” she whispered, fingers already trailing down your stomach.
You didn’t even have time to respond before she was rubbing your clit again, perfectly in sync with Heeseung’s slow, brutal thrusts.
You were shaking.
Crying out.
Fucked full by one of them, played with by the other.
Heeseung groaned, hips slamming harder now. “You like this? You like getting fucked while she watches? While she helps?”
“I’m gonna be doing more then just watching,” Star giggled, then slid two fingers into your mouth. “Suck.”
You obeyed without thinking, tongue swirling, moaning around her fingers as Heeseung pounded into you.
Everything was slick and wet and obscene.
The sounds—skin slapping, breathless gasps, Star’s filthy encouragement in your ear—sent you spiraling.
Your orgasm built fast, right there behind your ribs, a raw, burning need that grew with every thrust, every circle of her fingers, every filthy praise falling from Heeseung’s mouth.
“You’re gonna come, huh?” he growled, slamming in harder. “Gonna soak my cock while your best friend makes you suck her fingers?”
You sobbed, nodding frantically, thighs trembling.
“Good girl,” Star purred. “Come for us. Show him how wrecked you get for me.”
You came hard.
Violently.
Back arched. Mouth open in a silent scream. Pussy clenching around Heeseung as he groaned and fucked you through it, chasing his own release.
And just when you thought it was over—
Heeseung pulled out.
Star climbed over you.
And they flipped you onto your stomach.
“You didn’t think we were done, did you?” Heeseung murmured into your ear, cock pressing against your ass. “Not even close.”
You barely had time to catch your breath before Heeseung was flipping you over, pushing your chest into the mattress and dragging your hips up.
“Hands and knees,” he growled, voice rough, cock already rubbing between your folds from behind. “Just like that. Fuck—look at you.”
You trembled, legs spread wide, ass in the air, your slick dripping down your thighs. Every nerve was still buzzing from your last orgasm, but the moment he gripped your hips again, your body ached for more.
Star was in front of you now—sprawled back on the bed, legs spread, already playing with her clit as she looked down at you with that same wicked glint in her eye.
“C’mere, baby,” she said sweetly, voice dripping with lust. “Use that mouth again.”
You didn’t need to be told twice.
You crawled forward, shoulders low, your face level with her dripping cunt. The scent of her arousal hit you all over again—sweet, intoxicating, familiar. Your lips parted, and you licked a slow stripe up her slit, moaning at the taste.
That’s when Heeseung slammed into you.
You cried out against Star’s pussy, your tongue stuttering against her folds as his cock filled you to the hilt from behind.
“Fuck,” he groaned, already fucking into you with slow, punishing thrusts. “You feel even tighter like this.”
Star whimpered above you, her fingers tangling in your hair as she rocked her hips toward your mouth. “Don’t stop. Keep going. Just like that.”
You moaned into her, tongue sliding back into her heat, lips wrapping around her clit as your body rocked between them. Each thrust from Heeseung shoved you forward, pushing you deeper into Star’s cunt, your mouth wetter, messier, more desperate with every stroke.
The rhythm built fast—his cock driving into you, your tongue circling her clit, her thighs tightening around your head as she began to tremble.
“God,” Heeseung hissed. “Watching you eat her out while I fuck you? You don’t even know what you do to me.”
He reached around and slapped your ass, hard enough to make you jolt.
“Such a dirty girl,” he growled. “Taking my cock and making your best friend come at the same time.”
Star was panting now, thighs shaking. “She’s so good, Hee. Her mouth—fuck—she’s gonna make me come.”
And you wanted that. Needed it. You pressed your tongue harder against her clit, lips sucking, moaning into her like your life depended on it. The vibrations of your voice only made her cry out louder.
Heeseung’s thrusts grew rougher, deeper, his grip on your hips bruising as he chased his own release. You could hear the slick sounds of your cunt taking him, your spit on Star’s pussy, her whines as her orgasm built—
And then she broke.
Star came with a cry, her whole body shaking as her thighs clamped around your face. “Fuck, fuck—don’t stop,” she gasped, riding out the waves, her fingers tugging your hair as she pulsed and shuddered on your tongue.
Heeseung was right behind her.
“Shit—baby, I’m gonna—fuck—” he growled, slamming into you one final time before he buried himself deep, spilling inside you with a broken moan.
You collapsed between them, face still sticky with Star’s slick, your cunt still fluttering around Heeseung’s cock as he stayed buried in you, panting.
The room was silent except for your heavy breathing, the faint thump of music from the party down the hall, and the sound of skin still sticking together from sweat and cum.
Star giggled softly, brushing hair from your face as she leaned down to kiss you.
“You okay, baby?”
You couldn’t even answer.
Just smiled against her mouth, wrecked and satisfied, and moaned softly as Heeseung pulled out behind you with a wet, sinful sound.
“Don’t fall asleep yet,” he murmured, lips against your shoulder, thumb brushing between your legs to collect the mess he left behind. “We’re not done.”
