had to cool down while writing this wheww!
You knew the outfit was a mistake the second you stepped inside. A low cut tank top and shorts, gold necklace dangling against your collarbone, the inferno that was going on lately was just too much.
Your eyes immediately found Kagami already seated on the couch in Aomine’s bedroom, arms crossed, red shirt loose on his frame, and his legs spread like he didn’t know what to do with himself. He glanced up when you entered—and then did a double take, clearly not expecting you to show up looking like that.
You stared back with the exact same silent energy.
The bedroom was dimly lit, a soft blue from the LED strip running above Aomine’s desk, and the TV was already playing. Some god-awful thriller flickered across the screen—overacted, over-scored, under-budgeted.
Aomine was lounging beside Kagami, legs kicked up on the low table. His eyes flicked to you with a cocky grin. “Took you long enough.”
You rolled your eyes and shut the door behind you, dropping your bag by the corner before sitting down on the couch. You left space between yourself and both of them, but somehow Aomine still managed to lean just a little too close. You could feel his arm behind your back, his leg casually brushing yours and your lips curled slightly with irritation. After about fifteen minutes of silent sitting from just watching the film, you exhaled—bored.
“Okay,” you muttered. “This is terrible. Do either of you have actual taste?”
Kagami cleared his throat. “I brought a game.”
Aomine snorted. “Let me guess. Uno?”
Kagami ignored him and pulled out a card deck from his bag—black and red with golden lettering across the box. “Twenty Questions or something. It’s like Truth or Dare, gets people talking.”
Aomine raised a brow. “Gets people fighting, more like.”
You leaned forward and took the deck from Kagami’s hand. “Honestly? I’m desperate enough to give it a shot.”
Aomine shrugged. “Fine by me.”
None of you noticed Aomine slip a couple of other cards into the deck while you were shuffling the half in your hand.
Five rounds in, the game was mostly harmless. It wasn’t until Kagami pulled a card and paused that the air shifted. He stared at it, blinked then frowned hard.
You hovered over. “What does it say?”
Kagami glanced at you, red creeping up his neck and Aomine smirked.
“Kiss the person to your left,” he muttered, voice tight.
You closed your eyes, and then slowly brought your palm to your forehead, sighing. “You have got to be—”
“I’ll do it,” Kagami blurted and you froze, unsure.
“…If you want to?” Kagami added and looked like his head might explode, but his eyes were locked on yours, steady and serious now, like he’d made up his mind and there was no backing out.
You straightened slowly, studying him. His eyes flickered to your lips once—then back to your eyes.
And then he leaned forward and kissed you. It was chaste, barely any pressure at all and his lips were warm and gentle, like he was hesitant. Unsure on what was okay, what was fine to cross the line. Despite this, his kiss lingered and your initial thoughts on the two began fading, your eyelids closing without your permission.
The moment broke with a loud, theatrical scoff.
“That’s it?” Aomine said, grinning like the devil.
Kagami pulled back, flushing deeply. “Shut up.”
“Nah,” Aomine said, already hovering over the table toward you. “Lemme show you how it’s really done.”
You blinked, still flustered from the kiss. “What—”
Before you could finish, Aomine’s hand found your wrist, fingers light but firm, pulling you toward him. He looked at you—really looked—his eyes trailing from your eyes to your nose to your mouth like he was mapping out his path before taking it.
“You cool with this?” he asked, voice low. You hesitated but your hormones didn't, tingling with anticipation.
“…Yeah.” And then he kissed you. Aomine kissed like he meant it. With an open mouth and slow drag of his lips, his tongue brushed yours, and your breath caught before your palms pressed flat against his chest, to push him away or keep him close, you didn’t know. You melted into it for a second too long.
When you broke apart, breathless, the room felt smaller.
Kagami scoffed. “That was sloppy.”
“Oh?” Aomine leaned back with a lazy smile. “Jealous?”
Aomine chuckled, licking his bottom lip where your gloss had smudged. “Want me to teach you, Kagami?” You were oddly quiet. Your breath caught in your throat and you flicked between the two of them.
You didn’t feel like you had the upper hand anymore, that’s for sure. Clearing your throat once, then twice, you reach over, murmuring, “my turn,” and for the first time—your voice actually cracked. You snatched a card from the pile, not looking at either of them as you flipped over. The silence was broken only by the soft hum of the TV still running behind you. Your eyes scanned the text and you blinked.
“Sit on the tallest person in the room for a minute.” You read slowly and you felt your jaw clench. Gaze narrowed, your head spun to glare at Kagami who was already turning red, rubbing at the back of his neck.
“Where the hell did you get these cards?”
“Uh...my captain. I didn't know they had that type of stuff.”
“Sure you didn't,” you said, card still in hand. You heard Aomine laugh at you outright, head tipping back. “C’mon princess, gotta play fair."
You sighed heavily, looking between them. It was obvious who was taller. You slumped a little and you muttered under your breath. Then, with the grace of a reluctant queen, you crawled across the plush floor of Aomine’s bedroom and planted yourself onto his lap.
The second your thighs straddled Aomine’s, his hands instinctively found your waist. Not greedy—just firm. His thumbs brushed over your sides, and you felt your breath stutter, even as you kept your face blank. Kagami, seated directly across from you, was visibly fighting for composure. His hand twitched against the carpet.
Aomine smirked behind you. “Comfortable?” You didn’t dignify it with an answer.
Kagami grabbed a card before the minute could even begin, his movements brisk and irritated. “My turn.” Even though it wasn’t. He flipped it, eyebrows drawing together in a dark scowl as he read it. Then froze.
“What’s it say?” Aomine asked lazily, clearly enjoying himself. Kagami hesitated. Then muttered lowly, “Give the person with the longest hair a… hickey.”
Your brows arched. “You’re joking.” You glanced at Kagami. His face had gone full crimson, ears pink to the tips. Your hair fell just past your collarbone, loose from the heat of the room and the tension. The neckline of your top dipped, leaving a perfect canvas along the curve of your neck.
Aomine was already chuckling. “Come on, man. You’re redder than a damn tomato.”
Kagami glared. “Shut up.”
You sighed and slid off of Aomine’s lap, crawling across the short distance between them, then shifting so you were seated just in front of Kagami.
You pulled your hair back with one hand and tilted your chin up slightly, exposing the side of your neck to him.
“Go ahead, Kagami or are you chicken again?” Aomine drawled.
“Enough Aomine,” you said, voice like cut glass. You turned your eyes back to Kagami.
“I’m letting you,” you added, quiet but firm. He leaned forward slowly, hesitating once just before his lips brushed the slope of your neck. You could feel the heat of his breath before anything else. Then, he kissed and again, lower. And finally—he pressed a firmer kiss, letting his lips linger. His teeth grazed, gently, before he bit down just enough to make your pulse jump. You sucked in a breath.
A small sound escaped you, barely a hum but it was enough to make the other man click his tongue.
“I’m getting fomo,” he muttered, shifting from behind.
You had just started pulling away from Kagami when Aomine’s hand found your chin, turning your face toward him—and suddenly his mouth was on yours again, kissing you like the moment owed him something. This kiss was deeper than the last, more desperate. Your breath caught, but your mouth responded before your brain could stop it.
You didn’t know how this game escalated this quick, all you know is you suddenly found yourself on your knees, the carpet rough under your legs as you looked up at them—Aomine towering with that lazy smirk, and Kagami awkwardly avoiding your eyes, his cheeks flushed deep crimson.
The redhead pretending to study the wall turned his head and Aomine—well being him wasn’t so subtle, gaze dipping to your bare chest before locking eyes with you, a flash of smug satisfaction crossing his features. You rolled your eyes and crossed your arms, unimpressed. “Can I stand now?”
Aomine nudged Kagami with his elbow. He responded by sighing irritably, looking at the clock. “Nope, you still got time,” he muttered.
You exhaled through your nose, head dropping as your fingers drummed endlessly on your thighs. Aomine tilted his head slightly, amusement dancing in his expression.
“You don’t look bad like this,” he said, voice rich with teasing, “Actually kind of cute—suits you.” He proceeded to then nudge Kagami again.
Kagami frowned. "What are you-"
But then he glanced down at you, and something shifted in his face. Slowly, a grin started to pull at his lips, like he hated to admit it. "He's right. As much as I hate agreeing with this guy."
You scowled and smacked Kagami's hand away when he reached to pat your head. "Fuck off," you snapped, looking to the side to hide the way your heartbeat stuttered. That touch had done more than you wanted to admit.
"Babe," Aomine murmured with a laugh, "your thighs are tensing."
You didn't answer, but started to rise—only to be stopped by a hand on your shoulder, gently but firmly pushing you back down. Aomine wasn't smiling anymore. His expression had darkened with something heavier.
You shot him a glare, then turned that same heat on Kagami—until you finally noticed the tension in both of them. Your eyes dropped, and your lips curved upward into a sly, slow grin.
"Oh? You two are really this easy?" you asked, voice sugary and mocking. "All it takes is a pair of tits and you're this hard?”
Kagami flushed deeper but didn't hide himself.
Aomine shrugged with a crooked smirk.
"Can't blame us," he said. "But the real question is... what are you gonna do about it?"
You leaned back slightly, gaze flicking between them. The clock ticked past your time limit but you didn't move. A spark lit in your eyes, something wild and wicked tempting you from the inside.
"Nothing," you said smoothly—but your tone suggested otherwise.
You crawled forward just slightly, palm trailing up the inside of Aomine's thigh, eyes locked with his. His breath hitched, and you felt the shift in the air as Kagami took a half-step closer, caught in the gravity of your pull, straight into your face.
"I'm just horny, don’t think much of it.” you grunt under your breath like it was a warning-to them, or to yourself, like you weren’t sure. In no matter of seconds—Kagami was bare, flushed, his cock twitching right near your face, eyes wide with disbelief at just how far this had gone, and how you let it.
"You're actually—fuck," Kagami muttered, rubbing the back of his neck, like the sight of you between them had short-circuited him.
"Don't get shy now," you smirked, hand wrapping around the base of his dick without warning. He hissed out a breath through his teeth, his head dropping as your grip tightened just enough to make him twitch again.
Beside you, Aomine's hips rolled forward lazily, letting you feel the weight of him pressed against your palm. "Keep teasing like that," he muttered into the air, voice low and dripping,
"and I'll make sure you're the one begging."
You laughed-genuine, amused, wild. "Who said I wasn’t already?” Then you spat into your palm, dragged it over Kagami's length without breaking eye contact. The sound he let out wasn't even human. His hips jerked forward once, just once, and you rewarded it with a little twist of your wrist. You heard a small tsk from Aomine and you smiled, pulling his sweatpants down.
"Easy," you teased. "I've got two hands for a reason." You reached and found Aomine's cock next, hot and heavy and already leaking. He groaned when you gripped him, his breath hitching as he buried his face in his shoulder, trying to keep composure.
"Fuck," he muttered, "Imagine what your mouth's gonna do."
You didn't give him the satisfaction of an answer—you just leaned away and licked a slow stripe up Kagami's shaft. He cursed, both hands flying to your shoulders, like if he didn't anchor himself, he might lose it right there.
You took him into your mouth-slow, deliberate, letting him feel every inch of heat and spit and tongue. His head fell back with a broken moan, muscles shaking with restraint.
“Look at you go,” Aomine teased, bucking his hips into your palm. You didn't answer—mouth too full. But you lifted your hand and gave him a slow stroke anyway, twisting your wrist just right, feeling him twitch against your palm.
"Get up,” Aomine muttered, voice rough. You were flipped on the bed before you could blink—Kagami's hands guiding you to your hands and knees, his fingers lingering like he didn't want to let go. Aomine was behind you in a flash, kneeling between your thighs like he'd waited all damn day for it. In front of you, Kagami was kneeling as well, shirtless, chest rising and falling like he was holding back. His eyes were locked on yours, jaw clenched. You could tell he hated seeing you on someone else’s bed, especially his bed.
“So where is this going now?” Kagami asked, voice flat, but laced with heat, eyes drifting from your eyes to your chest.
Behind you, Aomine leaned down, his voice brushing your ear. “I think she’s smart enough to figure it out.”The air between the three of you was thick. No one said what they really wanted to say directly. You were caught between two storms—Kagami’s burning stare and Aomine’s lazy possessiveness. And you didn’t want to back down from either.
“You two are exhausting, stop talking as if I’m dumb,” you muttered, eyes flicking between them. Aomine chuckled low behind you. “Then why’re you still here?”
“Because I’m curious,” You shifted slightly, legs tingling from their bent position, which only pushed you further against Aomine's cock. He let out a sharp whistle. You bit your lip and sighed, already regretting how badly you wanted this, but the heat between your legs was louder than your pride.
"Sure you are,” Aomine grinned into your neck. "Don’t kid sweetheart, turns you on being between us like this doesn’t it?”
Kagami said something under his breath, then leaned in, the line of sight between your eyes and his cock undeniable. "Ignore him," he muttered. "Just...continue sucking me."
You kissed slowly along his V-line, your hand wrapping around him—thick, warm, heavy and still wet from your spit. His breath caught and Aomine hummed behind you, lazily grinding his length between your thighs, smearing your slick along himself without going in. "Atta girl," Aomine murmured. "Give us a performance."
Kagami looked down at you, embarrassed, but too hard to stop you. His cheeks burned as your fingers stroked him, slow and reverent. You tapping his tip on your tongue, watching the way his body shuddered. Aomine leaned over you, one hand still gripping your hip as he glanced down at the lace panties crumpled on the floor. "Lace?" he scoffed. "You did know what you were doing."
You moaned around Kagami's cock, the sound muffled, needy. You hollowed your cheeks and watched him try to stay composed—and fail. Drool slid down your chin as you pulled off with a wet pop, then licked your lips and smiled. "I can't wait anymore," you said breathlessly.
Aomine scoffed. "Why don't / get to go first?"
"Because you talk too much," you muttered, then added, "And I doubt either of you wants your dicks touching inside me, right?" You lay back against Aomine's thighs, your legs spreading shamelessly. Your body glistened, already soaked. He knew—knew down to the gut—that this view of you would’ve been perfect if not for the way tanned hands were roaming across your breasts like they belonged there, and Aomine’s mouth slotted against yours shamelessly.
"Well? Fuck her before I do," Aomine said smugly, pulling away with gloss and spit smeared over him.
Kagami grunted, grabbed your legs, and pushed them apart to kneel between them. He dragged himself along your slit, spreading the mess, and you exhaled, breathless.
"Get it over with already," you tried to say, but the words broke apart little by little when he pressed into you, slow and thick. The stretch forced your mouth open and your hand gripped Aomine’s thigh as you groaned. Your body twisted—Kagami fucking you deep and slow. The heat—of him and the sun—was overwhelming. The sounds of skin meeting skin, your gasps, their ragged breaths filling the room. Aomine watched you fall apart, his face unreadable except for the tension in his jaw.
"Shit," he said quietly. He wasn’t going to let his rival beat him this time. Once was excusable—barely. But twice? Never. The moment your quiet gasps turned into breathless moans for a second too long, he dragged his palm across your collarbone, chest, stomach—reaching to press low, tantalising touches onto your clit. "She's not loud enough, Kagami."
"Shut up," Kagami snapped, but his hips sped up.
You moaned out, voice boosted a little louder. "Right there, Kaga..."
Aomine rolled his thumb over your clit, smirking as your thighs twitched. "C'mon, Kagami. I’ve heard her sing louder at practice than this." Your brows furrowed, lip tucked between your teeth as you tried to block them out—focused on your pleasure.
Kagami gritted his teeth, looking down on you “ Don't worry about him, just focus on me."
But his focus cracked the second you gasped, trembling under Aomine's touch as his fingers increasingly moved over you.
"Don't rub too fast Aomine," you panted. "I'm gonna-"
"Did you hear that?" Aomine teased. "She called my name, not yours.”
"Yeah, and who's actually inside her?" Kagami snapped, adjusting his angle to go deeper. Aomine smirked, that cocky, unbothered kind—the kind that said he’d already won. Then, he dipped his head and bit lightly at the curve of your neck, fingers slowling slightly.
“You know…” he muttered, just loud enough for Kagami to hear, “if I was the one doing the job, she would’ve been satisfied by now.”
Kagami’s jaw clenched. His eyes shut for a second, breath heavy and ragged through his nose before— he let go of your thigh and swung.
You gasped but the punch never landed. Aomine leaned back, easily dodging it, lips still curved like he was enjoying every second of this. The problem came when the motion shoved you forward slightly—folded in half between them and your moan breaking in half—Kagami’s cock slipping out from inside you.
"Thanks a lot, you fucking hotheads," you said weakly, approaching orgasm gone.
Kagami glared. "Let's switch if you're so confident."
“Of course.” Aomine flipped you easily, laying you on your stomach with your ass arched up. He rubbed himself through your slick again, lining up. You glanced back and blinked—he was thick.
Stupidly thick, how you didn’t really notice while jerking him off was beyond you.
"Bigger, right?" he said, cocky. You rolled your eyes, about to answer—but Kagami grabbed your chin and forced your mouth open.
"Fuck you look so good for me,” Kagami whispered, brushing your lips with his thumb.
"For us," Aomine corrected, smirking at the two pairs of eyes that rolled back so far into their heads at him, it was almost synchronized. Kagami chose to kiss you, tongue deep, possessive, fighting to kick him out. You whimpered against his mouth, bits of pride unraveling with every second.
“Sorry, can’t wait any longer.” Then, without warning, Aomine pulled your hips back and slid in—hot, deep, slow. Your moan was muffled in Kagami's mouth. Kagami sat up in front of you again, stroking himself slowly, watching your face twist with every thrust Aomine delivered.
"Open up,” Kagami said, voice dark, needy.
Your mouth parted, tongue out, spit already dripping from your lips and Kagami easily slid back in, groaning as you wrapped your lips around him like you'd been starving for it. Your moans were muffled, guttural. Each time Aomine thrust in, it made your lips sink further down Kagami's cock. You were forced to gag and drool further—but you kept going, eyes rolling when Kagami grabbed your hair, using it to guide your rhythm.
"Filthy girl," Aomine murmured behind you. "Taking dick in both ends after all the denying you’d never be with one of us."
Kagami chuckled breathlessly, sweat glistening at his temples. "You hear how wet she is? Shit— she loves this."
Aomine reached around, fingers finding your clit again, rubbing with slow, devastating circles that made your legs tremble. Kagami stared down at you, his cock twitching in your throat, your lips wrapped tight, your jaw aching—and still you kept moaning. Then Aomine leaned over, breath against your ear. "Say it," he growled. "Tell us you fucking love it."
You pulled off Kagami's cock with a wet gasp, panting, spit stringing from your lip to his tip.
"Nah, you guys love it.” you rasped. Both of their heads tilted slightly, lips twitching into smirks. Still standing on business, still in ‘control’, even though they’d reduced you to this. Kagami wiped your lip with his thumb gently, then shoved himself right back into your mouth. "Not done."
Aomine groaned, picking up the pace, thrusts hitting harder, deeper. "Choke on him—fuck.” You reached back blindly, fingers digging into Aomine's thigh as you choked on Kagami again. Your legs were shaking. Every part of you was shaking. And you knew you were close—so damn close. "I—fuck—I'm gonna-" you tried to say, voice strangled and muffled between moans and movement and their dicks.
Their eyes trailed across you slowly.
Kagami's jaw clenched as he watched the bounce of your ass with every roll of Aomine's hips, the slap of skin echoing off the walls.
Aomine, in contrast, was lazily enthralled by your mouth, watching your lips stretched around Kagami's length, cheeks hollowed, head bobbing, your throat working like it was made to take him.
You were a mess, and they were feeding off it—off each other.
Most men would be tense in this kind of scene. Competitive. Jealous. But Aomine just smirked, eyes dragging over Kagami's chest, his arms flexing where they braced above your head, his face twisted in restraint.
"Can't believe how quick you folded," Aomine said, voice rough and low, watching you without shame. "Not even half an hour ago you were mouthing off like we couldn't handle you."
You pulled off Kagami's cock, till his tip pressed on your swollen lips, drool slipping down your chin. "Still can't," you rasped. "I'm doing most of the work."
Kagami groaned, biting back a laugh. "You're unbelievable."
Aomine leaned forward slightly, his hand still gripping your waist. He wasn't looking at you now—his gaze was on Kagami. "That outfit was screaming fuck me. She knew what she was doing."
Kagami narrowed his eyes, bracing harder against the mattress. "What the hell are you staring at?"
Aomine smirked. "The veins in your neck," he murmured. "The way you're about to lose it." He was closer now, breath brushing Kagami's jaw, their tension spiking in the air.
You pulled back from Kagami completely, coughing softly, eyes flicking between them. "Oh, for fuck's sake," you muttered. "Just kiss already."
Kagami glared down at you. "Use your mouth properly."
But Aomine's hand didn't move from Kagami's shoulder. And before either of you could say another word, his fingers threaded between his hair on the nape of his neck.
“Shit—you gonna kiss me?” Kagami joked lightly, but his lips parted as if he anticipated it and Aomine tugged him forward, with a soft nod.
The kiss was soft. Kagami's eyes widened, breath stolen right from his chest. But he didn't pull away. He leaned in, and the tension snapped like a rubber band—sharp and hot. Their mouths moved, tongues brushing like they'd been thinking about it far too long.
“That was…” You trailed as they broke apart just slightly, still close enough to breathe each other in, eyes locked in something hotter than rivalry now. Then Aomine looked down at you, lips wet and curved.
"You gonna keep watching, or get back to work?" he said lazily. And just like that, Kagami shoved back into your mouth without another word, groaning like he needed it more than air. Aomine's hands were already roaming again, fingers between your legs, pressing against your slick heat like he was claiming the rest of you.
They didn’t need to say much.
That kiss said everything.
It knocked down the last of the tension between them—and you. Aomine finally pulled out with a low growl, his cock slapping against your ass, soaked with your slick. He gripped himself tight, pumping hard, watching you get used like a toy by Kagami.
"Fuck—look at you,” Aomine groaned deep in his chest, hips jerking forward uselessly before he gripped your ass with one hand and came in thick, hot ropes across your back, thighs, and that perfect ass of yours. You moaned around Kagami's cock at the sensation, the mess, the filth of it all.
"Shit—shit—“Kagami groaned, pulling back just in time to spill across your lips, your tongue, your chin. His thighs shook. "Take it—just like that, fuck-" You did. You sat there, panting, covered—mouth open, jaw slack, cum smeared across your skin like a trophy.
The room fell into a heavy silence, just breathing. The hum of the AC. The creak of the bed under shifting weight of three people. You wiped your mouth with the back of your hand, slow, dramatic, and looked up at the two of them with a raised brow.
"That's it?" you said, voice raspy, mocking. "All that and I still didn't get an orgasm?"
The boys exchanged a glance, smug and dangerous.
Aomine leaned in. "You don't like us, remember?"
"Finish yourself off," Kagami added with a smirk.
You opened your mouth to protest—but Aomine was already between your legs, tongue flicking expertly, and Kagami's fingers curled inside you, drawing gasps from your throat.
Your orgasm hit like a wave, your body trembling as you slumped deeper into the bed.
You missed the moment Kagami stuck his fingers into Aomine's mouth, sucking lazily before they both leaned back, smooshing you between their sweaty bodies.
"You satisfied?" Kagami asked, voice husky.
You smirked through the afterglow. "I don't know. I still don't like you guys that much.”
Aomine grinned, “Then maybe…we just need to try harder.” Hands on your waist, on your neck, in your hair. Warm mouths pressing slow, hungry kisses to your skin—your cheek, your collarbone, the corner of your lips. The real adventure was about to begin.
