your body settles against the sheets when a scene of shane kissing ilya flickers across your tv screen, your breathing picking up slightly as your panties start to feel a little uncomfortable, too hot to pretend it’s not having an effect on you.
you sigh, slipping your hand slowly into your sleep shorts, but before you can actually do something about it, the front door of your flat opens and you sit up quickly, frustration crawling up your spine.
“it’s my turn, you had her last weekend,” beomgyu’s voice pulls your attention, along with footsteps echoing down the hallway.
you come face to face with your two boyfriends, kai just behind beomgyu, both of them frowning until they see you and their expressions soften.
“what’s going on now?” you roll your eyes, wrapping your arms around beomgyu to press a quick kiss to his lips, repeating the same with kai.
“i just missed you,” kai admits, slipping his arms around your waist, hands sneaking beneath your sleep shirt.
“that’s not the deal,” beomgyu rolls his eyes this time, walking over to your bed. “this weekend’s mine.”
“i’m just asking to join,” kai murmurs against your neck, his lips brushing your skin in an attempt to convince you. “pretty, please…” your skin prickles, your head tilting slightly toward beomgyu.
“you can’t fight over being with me,” you scold, though you’re melting when kai’s teeth graze that sensitive spot. “that’s not how this is supposed to work.”
beomgyu sighs, nodding, about to answer when a low moan slips from the tv, and both of them turn to look at the show.
“heated rivalry again?” kai laughs against your neck, his hands tightening on your waist.
“it’s my comfort show,” you defend, glancing back at the sex scene. beomgyu watches for a few seconds before looking away, almost regretful.
“i don’t get why you like watching two guys kiss so much,” he says, settling into the pillows, patting the space beside him for you to join.
you crawl across the bed, resting your head on his chest, kai joining on the other side as he wraps an arm around your waist.
“it’s the same as you imagining me with another girl,” you explain casually, and kai laughs behind you.
“fair enough, i’d kill to share with another girl.”
beomgyu scoffs, his arm coming around your shoulders to pull you closer. “i’d kill not to share you with anyone.”
you laugh softly, tilting your head toward him. “you woke up extra jealous today.”
beomgyu chuckles, pressing a kiss to your head before looking back at the tv, shifting a little uncomfortably.
“you can’t blame me either,” you add, turning back to the show. “god forbid a girl wants her boyfriends to kiss.”
they both look at you as the words leave your mouth, kai the first to respond with that teasing tone of his. “you want us to kiss?”
beomgyu tenses beside you.
“a girl can dream,” you reply, glancing at him over your shoulder. “sometimes i imagine it, and it’s kinda hot.”
kai laughs, shooting beomgyu a look over your head. “what, you scared?”
beomgyu huffs, meeting his gaze with that same competitive glint in his eyes.
“no, you?”
kai shifts after that, sitting beside you on the bed and bracing his weight on one hand against the mattress. beomgyu follows, sitting up carefully so you can move now that you’re no longer resting on his chest. they look at each other, like they’re still silently competing to please you.
“wait, are you actually going to kiss?” you sit up, your back pressed against the headboard as you watch them facing each other.
“why not?” kai says, playful. his eyes flick back to beomgyu after answering you. “i’ve always thought you were hot.”
beomgyu rolls his eyes, used to kai trying to get under his skin and succeeding 99% of the time. only this time, he doesn’t want to lose.
“good taste,” he shrugs, glancing at you when he hears you laugh, his lips curling into an involuntary smile even as his jaw tightens when kai leans closer than he should.
you watch them closely, convinced they won’t actually kiss. you know them, they barely tolerate each other, it’s impossible.
“fine, let’s do this,” beomgyu says, tilting his head toward kai and shooting him a look. “if you bite me, i swear—”
kai leans in to shut him up before he can finish, eyes closed, lips pressing against beomgyu’s. he tries to look unbothered, but you can see his fist clench against the sheets.
beomgyu’s eyes close too, resisting the urge to pull away at first.
your eyes widen slightly in surprise, a smile forming on your lips as you lean in to get a better view.
only three seconds pass before they pull apart, not saying a word.
you roll your eyes. “that’s it? you didn’t even—”
but you’re cut off when they both lean in again, beomgyu tugging kai in by the collar of his shirt while the blond pulls him closer by the waist. your mouth falls open in surprise, almost shock, as you watch their lips meeting again, their tongues clashing in a silent fight over who kisses better.
your thighs press together, trying to soothe that growing ache between your legs.
kai pulls beomgyu against him, noticeably stronger with the difference in their builds, and beomgyu simply lets himself fall, kai’s back hitting the mattress, beomgyu’s chest pressed to his.
the room fills with the sound of their kisses, loud, careless. kai’s quiet grunts mix with beomgyu’s low moans, both sounds reaching your ears, making your mouth water.
beomgyu’s hands slide up into kai’s hair, fingers tangling on instinct, his skin prickling as kai’s hands come up to hold his jaw, firm, yet careful at the same time.
beomgyu braces one hand beside his head, but a surprised gasp slips out when, in a quick movement, he finds himself pinned beneath kai.
your eyes follow every movement, a heavy breath leaving your nose. the tv keeps playing in the background, but you’re no longer interested in ilya and shane. you only want to watch your boyfriends making out hungrily right in front of you.
one of kai’s thighs slides between beomgyu’s legs, pressing against his boner, which only grows the deeper the kiss gets, even as he tries not to react too much.
he tilts his head back when his body demands air, not giving beomgyu time to recover before his lips trail down along his jaw to his neck, kissing and nipping playfully until beomgyu starts to squirm beneath him, his moans growing rougher, louder. his head tilts unconsciously, giving the younger more space to do whatever he wants against his skin.
your eyes meet beomgyu’s for a brief second before they roll back and then shut, his body reacting when kai’s teeth find that sensitive spot—the one you know makes him fall apart.
“what were you saying about biting?” kai growls against his skin, his hand sliding up to his neck to squeeze gently, stealing his breath for a second.
beomgyu can only answer with a low groan, especially when he feels kai’s thigh press against his erection, painfully hard beneath his jeans.
“come here,” kai says, looking at you over his shoulder. voice breathless, dark eyes. “you started this.”
beomgyu’s moans fill your room, louder and way needier this time, when your lips meet the free side of his neck. you suck at that sensitive spot, leaving small marks that make his hips twitch involuntarily, almost like a reflex.
your hand travels down his abdomen until it reaches the waistband of his jeans, and without even asking, kai unbuttons them so you can keep going. you pull his boxers down, wrapping your hand around his cock and stroking him slowly, feeling him throb in your grip the way he always does when he’s too worked up.
“fuck—” his voice comes out rough when kai joins in too, his warm hand stroking beomgyu’s balls while you jerk him off at a slow pace.
his hips lift off the bed, his eyes squeezing shut as he feels both hands giving him exactly what he needs.
“let me go down,” you ask kai, breathless, already lost in the moment. it comes out more like a plea than an order, and you only move when the blond nods, pressing his lips back against the brunette’s.
beomgyu moans into his mouth when he feels your lips wrap around the tip of his cock, your tongue circling slowly to taste the precum, his back arching in response.
“you’re so needy it’s pathetic, y’know that?” kai groans against his lips, almost mocking, not giving beomgyu time to reply before he pushes his tongue back into his mouth, tasting him, swallowing every sound he makes.
one of his hands comes up to grab kai by the neck, pulling him closer to deepen the kiss, his lips moving against his as he tries not to moan into his mouth when you take him deeper. you feel his other hand tangle in your hair, gentle, never pushing your head down. he’s never liked doing that. but god, he’s weak when you’re sucking him off like this.
kai pulls back just enough to watch you going down on beomgyu, and his eyes darken at the thought of joining in. he’s never really felt attracted to men, this probably isn’t an exception, but beomgyu looks so wrecked, so gone, that it’s enough to make his own cock hard just from the sight.
he lifts beomgyu’s shirt, lowering himself along his abdomen, his tongue dragging over his abs and making him shudder, beomgyu’s fingers tangling in his hair as he feels him getting closer to you.
to his cock.
you lift your head, meeting kai’s gaze, and he leans in to kiss you—your tongues slipping from each other’s mouths to beomgyu’s tip, sharing the taste of him between you. beomgyu lets out a rough moan at the sight of you kissing right over him.
“see what you do to us?” kai groans into your mouth, gripping the back of your neck to guide you back down to your blowjob. his hand moves to your hair, this time guiding your head faster.
beomgyu arches his back when he feels you take him into your mouth faster. “shit, stop— ‘m close.”
“already?” kai teases, lifting his head to look at him while tugging your hair to push you deeper onto his cock, your gagging making beomgyu shiver around the sensation.
“fuc— ah— fuck you, kai.”
the blond rolls his eyes, not looking away as he lowers himself, getting closer to beomgyu’s balls, giving them a slow lick that sends a shudder through him. he can’t quite explain what exactly about all of this is turning him on so much.
he loosens his grip so you can catch your breath, this time bringing the tip of beomgyu’s cock closer to his mouth to lick it. he glances at you—you know what he’s asking without words, and you don’t hesitate.
you lean in again to join him, licking the tip from the other side while your hand strokes the mess of desperate moans that beomgyu has become.
his hips jerk upward, completely out of his control, trying to hold back even as the knot in his abdomen tells him he’s right there. his eyes squeeze shut, fists clenching at his sides as his whole body tightens, bracing for the orgasm that’s about to hit—
“stop,” kai orders, making you pull back and take your attention away from beomgyu right when he was about to cum.
his eyes snap open instantly, looking down, chest rising and falling with arousal, adrenaline, and the almost orgasm that just slipped away.
“why—”
“shut up,” kai cuts him off before he can complain, shifting to rest his back against the headboard. he unbuttons his jeans, finally freeing the erection that had been aching, trapped. “beomgyu, come here.”
“but—”
“don’t make me repeat myself.”
you glance at the brunette, licking your lips, used to kai being this demanding in bed. something beomgyu clearly doesn’t know.
his hips meet beomgyu’s, his whines filling the room as he tries to adjust to the new sensation of being taken for the first time— it hurts, but it’s so good he doesn’t know what to hold onto to keep from losing himself in it.
his back rests against kai’s chest as he thrusts into him without mercy, like he doesn’t realize how overwhelming it is, pleasure tangled with pain. his hands grip beomgyu’s hips, guiding the movement, pushing deeper each time.
kai’s breathing ghosts against his ear, and beomgyu chases that denied orgasm, pushing his hips toward your mouth, hitting the back of your throat, his eyes rolling at the way you gag around him. you glance up at him for a second, completely captivated by how desperate he looks; brows furrowed, lips parted, whines spilling out of him, begging for more, his abs tightening with every shift of sensation.
“ride him,” kai orders between rough breaths and low grunts. beomgyu turns to look at him like he’s lost his mind, like it’s too much to handle, but kai pushes harder, forcing his back to arch, his eyes squeezing shut.
the blond stops his thrusts so you can take your time, his eyes on you as his breath brushes against beomgyu’s ear, who feels his eyes gloss over when your sweet pussy tightens around him, hugging his width as you take him inch by inch.
a moan slips from your lips, because beomgyu has always been big, his cock always forcing you to pause and adjust when he enters you, hitting exactly the spot you need to cum. he moans too, a little higher pitched than usual, because he can still feel kai inside him.
“are you ready?” he asks you, not beomgyu, and you meet his gaze. your hands rest on his shoulders to keep your balance, his cock throbbing inside you, begging you to start riding him.
you nod in response, a darkness in your eyes that could be enough to make beomgyu finish.
kai positions his legs in a way that makes it easy for him to thrust against beomgyu’s ass, slow at first not to drive him insane with too much stimulation, but he quickly pick up pace, unable to help himself, chasing a kind of pleasure he didn’t know a man could give him.
even if the position isn’t the most comfortable, you manage to move your hips up and down to match kai’s rhythm, your ass bouncing against beomgyu’s skin as you hear him moan loudly, desperate, trying to regulate his breathing and failing miserably.
his hands grip your hips, the only thing he can find to keep himself grounded while two of his weak spots are being stimulated like this. his eyes shift from yours to your tits, the way they bounce so deliciously making it impossible for him to look away.
“she’s so pretty, isn’t she?” kai praises you, his ragged breathing hitting beomgyu’s ear, earning a series of whimpers in response. “look at her tits, gyu. aren’t they pretty?”
beomgyu lets out exaggeratedly deep breaths, his hands sliding up your waist until they reach your chest, pinching your nips gently before losing control. kai’s hips slam into him so rough and unrestrained that it makes his cock push even deeper inside you as you bounce on top of him.
your moans are the quietest in the room, drowned out by the rough grunts tearing from kai’s throat and beomgyu’s whimpers as he feels his orgasm getting closer, not entirely sure which of the two of you is pushing him there.
“i… fuck, i wanna— oh my—“
he tries, he really does, but his brain can’t piece together coherent thoughts when his hole is being fucked like this, with a kind of burning pain that still hits something deep inside him that feels too good.
“this is all it takes to make you cum?” kai growls against his ear, picking up the pace of his hips and making beomgyu arch his back with loud whimpers, tears slipping down his cheeks. he’s enjoying it so much it embarrasses him to even think it, he doesn’t want to stop and process how good it feels to be fucked. though he can’t really think much at all.
“he’s so sensitive right now,” you add, breathless, bouncing against him with sharp, deliberate movements, the sound of your skin slapping against his almost as loud as his moans. your hands slide down from his shoulders to his chest, index fingers brushing over his hardened nipples, making him moan even louder as he looks at you like you’ve gone insane.
“yn— don’t—“
“mmh?” your thumbs start tracing circles, playing with his sensitivity. beomgyu presses his lips together, his head falling back against kai’s shoulder.
“too much— oh fuck, i need— please.”
kai lets out a breathy laugh, his hips snapping harshly against his ass. “oh, is he the begging type?”
beomgyu feels a tingle in his lower body, warning him he’s about to experience the best climax of his life.
“m gonna— fuck, don’t stop—“
kai and you share a look, like you silently agree to give it everything at once. the speed you set is enough to make beomgyu see stars, his lower abdomen tightening with that familiar knot. only this time, there’s another kind of pleasure tied to it, one coming from behind, from his most vulnerable spot.
his hands drop to either side, gripping the sheets tightly, arching his back to hit the perfect angle. his whole body tenses, and you catch the exact moment he lets go of any restraint, giving in to an orgasm so intense it makes his eyes roll back.
his hearing dulls, unable to keep up with your moans or kai’s, and even his vision starts to blur.
the only thing that leaves him is a strained, broken groan as you feel his cock spill inside you, filling you with the hot release he so desperately needed.
his body goes slack when kai stops thrusting, shifting to give him the space he needs. his body twitches, evidence of the best high of his life, as he tries to catch his breath.
“i’m not done here,” kai says, pulling your body toward him, his hands gripping your hips so he can position you the way he wants.
your knees press into the bed, back arched and ass up for him. his hands roam over your cheeks, giving it a small squeeze followed by a slap just to watch your skin bounce in response.
“can you take it better than him?” kai asks, almost mockingly, as he guides the tip of his cock to the entrance of your other hole. you glance back at him over your shoulder and nod.
“mhm, babe, please–“
his hand moves down, coating his fingers with your slick, spreading it over your second entrance and along his tip before pushing in slowly, letting you adjust to the feeling.
your face twists into pure pleasure as his length slides into you, and he groans at how tight you feel. he glances to the side, catching sight of beomgyu trying to sit up on the bed, his eyes unfocused, blissed out.
“you good?” he mouths, genuinely checking on him, while starting to thrust into you so you can get used to it, your moans sounding like music to both of them.
beomgyu nods, wincing slightly as he shifts position. he’s sensitive, but that doesn’t stop his erection from keeping hard, refusing to go down.
“c’mere, you can use her as a fucktoy,” kai gestures to him, while your cheek presses into the sheets and your whimpers are muffled against the mattress with every deep, delicious push.
you don’t have time to react when you feel your hair being pulled, forcing your head up, and just from the firmness of the grip you know it’s kai. beomgyu positions himself right in front of you, slowly stroking his cock.
“open that pretty mouth for beomgyu, doll,” kai tells you, his voice firm because it’s not a suggestion; it’s an order. you obey, caught between moans and soft cries from how good his cock feels pounding into you.
beomgyu slides his cock slowly into your mouth, his thighs trembling when your tongue traces along one of his veins and when his tip makes you gag.
“deeper, baby, take him deeper.” kai growls, his grip on your hair tightening. you don’t know how you manage it, but you let beomgyu’s cock slide down your throat, not hitting the back this time but letting it pass. the walls of your throat tighten around him, he lets out a low moan and places his hand in your hair too, pushing his hips toward your mouth to go deeper.
kai’s grip turns rougher, almost painful, and just from the depth of his groans you can tell he’s close but there’s nothing you can do except let him use you while you keep sucking beomgyu’s dick.
“fuck, yn, you take it so fucking well,” kai curses, feeling the knot tightening dangerously in his lower abdomen, warning him of his release. “all filled with our cum, is that what you wanted?”
you moan in response around beomgyu’s cock, the vibration making his body shudder. his eyes are on you, on the way you choke on him, but when he feels kai’s intense gaze on him, he lifts his head to meet it.
you don’t know which of them moves first and they probably won’t ever tell you, but they kiss again, this time over you. it’s messy, desperate, loud, all spit and pent up want. beomgyu feels the tip of his cock tighten in your throat, a clear sign his second climax is right there.
kai grabs your hips with one hand, thrusting hard and fast, chasing his orgasm, while his other hand comes up to wrap around beomgyu’s throat, squeezing almost without thinking. the sight of him gasping into his mouth is enough to push him over the edge.
and it’s enough to make beomgyu come again too, moaning against kai’s lips, breaking the heated kiss.
the cum spilling into your mouth slides straight down your throat as beomgyu rolls his hips slowly, making sure you take it all. kai’s thrusts slow, muffled groans leaving his throat as he tries to come back down.
your body nearly gives out when they both pull away from you, heavy breaths and unfocused eyes staring off somewhere in the room. your cheek rests against the edge of the bed as beomgyu collapses beside you and kai leans back against the headboard.
“you came twice, huh?” kai teases, breathless, earning a middle finger from the brunette.
“you know who hasn’t come yet?” beomgyu says, his gaze settling on you as you try to recover from being used like that.
kai smirks, something dark and amused crossing his expression as he leans forward and grabs you by the waist, pulling you back toward him.
to keep going.
