the room was pitch black except for the faint glow of moonlight slipping through the curtains. SUNGHOON's body–heat radiated like a furnace between sooha and you. the other woman was already softly snoring on his left, curled away like she owned the vacation house.
you tried to stay on your side of the bed, back turned, knees pulled up comfortably. but the bed dipped every time sunghoon shifted, and god, he kept shifting.
“stop moving,” you whispered, barely audible.
his low chuckle rumbled through the mattress, barely louder than a breath. “i’m trying,” sunghoon murmured back, grunting softly as he shifted again. “but you know how it is… we’re not sixteen anymore, and the bed’s gotten smaller.”
you almost scoffed—quietly, because sooha was right there. smaller? please. the bed was the same king sized it had always been in this house. the only thing that had changed was him.
aside from the additional body on the bed, sunghoon had always been tall, lean from all those years on ice, but now? twenty–three, he filled all spaces like it was his. broad shoulders, long limbs, solid build that always took up space.
he was the one taking up half the damn bed, legs almost stretched out if it weren’t for you pinching his hip to warn him still, one thigh brushing yours no matter how hard you tried to scoot away.
“liar,” you hissed under your breath. “you’re just… big.”
sunghoon shifted again, deliberately this time—his body rolling just enough that his chest grazed your back, heat seeping through your thin shirt. his arm draped lazily across the space between you, fingers ghosting over your hip.
you swallowed hard, trying to ignore how your body leaned into the heat of him. “why are you behind me like this?” you whispered, voice softer than you meant it to be. “there’s literally no space for me here.”
his chest pressed firmer against your back, his knee brushed the back of your thigh. sooha stayed blissfully asleep, her soft breaths steady against his shoulder.
“i’m comfortable sleeping on my right,” he murmured, warm breath hitting your bare nape. “always have been. don’t you know that?”
“unfortunately,” you shot back under your breath, but it came breathier. you tugged the blanket toward yourself instinctively, trying to create an inch of distance.
the fabric yanked back immediately—sunghoon pulling back the covers, holding it firm. “stop pulling it away,” he said quietly, hissing through his teeth. “you’re fuckin’ hogging it all.”
“i’m cold—!” you whispered loudly as he reeled you back in, flush against him again. his hips settled right behind yours and that’s when you felt it—the hard line of him unmistakable through the thin layer of your shorts, pressing right against the curve of your ass.
your stepbrother let out a slow breath against your neck. “then c’mere,” he managed, biting his bottom lip hard enough that you could hear the tiny wet, restrained sound of it.
the realisation hit you both at the same time: your thighs had parted just a friction without thinking, the subtle rock of your hips backward that you couldn’t stop. testing… teasing. you felt sunghoon twitch in response, his fingers flexed on your hips like he wasn’t sure to resist or grab you.
“shit,” he breathed, so quiet it got lost in sooha’s soft breathing. his girlfriend stayed curled against his back on the other side, oblivious, one arm thrown over his waist. the irony made your head spin.
god, you supposed everything about him just.. grew bigger. you arched your back the tiniest bit—enough to grind back against him this time. his sharp inhale was instant, chest expanding against your spine.
sunghoon didn’t say anything in response, but his hips just rolled forward in response—matching your rhythm, lazy but needy. his clothed cock slid against the cleft of your ass through the thin barrier of your shorts and his sweats. each push made your shorts ride up higher, fabric bunched until it felt like nothing was separating the two of you.
you bit your lip hard, stifling the whine that wanted so badly to escape. he felt the way your body trembled, and rewarded you by sliding one big, warm hand under your shirt, hiking it higher. your stepbrother cupped your tit fully, thumb brushing over your nipple once, twice, then pinching just enough to make your back bow.
“no bra?” sunghoon chuckled softly.
“fuck,” you mouthed silently, head tipping back against his shoulder. “they need to breathe, dummy.” you replied, feeling the coil heating in your tummy.
sunghoon smiled against your nape, kneading slow circles while his hips kept grinding, deeper now, rutting against you like he’s trying to fuck you through the clothes. the wet spot on your shorts was growing obscenely embarrassing; you could feel it every time he dragged himself along your folds.
you pushed back harder, rolling your hips in tight little circles, chasing the pressure. the bed creaked once, and you both froze for a heartbeat. sooha mumbled something sleepy, nuzzling closer to his back. sunghoon’s grip on your breast tightened in warning, but he didn’t stop moving.
if anything, he ground slower, deeper, letting you feel every thick inch slide between your asscheeks.
“shh,” he whispered against your ear, nipping the shell. “she’ll wake up.”
you clenched around nothing, thighs pressing together, and he groaned until it vibrated through both of you. “h—hoonie,” you moaned softly, clamping your bottom lip down from letting out another sound. the nickname slipped out like always when you were this far gone—sweet, desperate, forbidden.
sunghoon’s breath hitched and his hand flexed on your breast, fingers digging in with his index pressing down right in the middle of your nipple.
“shit,” he rasped. “can’t wait anymore.”
before you could process it, his fingers were hooking into the waistband of your shorts and panties in one tug—yanking them down just past the curve of your ass, bunching the fabric at your thighs. cool air hit your bare wet pussy, then his heat swallowed it all.
your stepbrother shifted behind you—quick, impatient—shoving his own grey sweats down enough to free himself completely. you felt him skin on skin now—and your eyes widened before the corner of your lips twitched into a smirk.
“no boxers?” you breathed, half–shocked, half–thrilled.
sunghoon let out a shaky laugh against your neck, lips curving into a smirk you could feel. “gotta let him breathe, baby. been hard since you climbed into this bed.”
he didn’t give you time to reply. just lined himself up again—thick length sliding right between your folds, this time with nothing in the way. the head nudged your entrance on every forward roll, teasing without pushing in, coating himself in your juice while he ground slowly and filthy.
“ngh…” you whined, arching your back harder. your thighs trembled as you tried to spread just enough for more friction. he hissed through his teeth, one hand clamping over your hip to hold you still while the other slid up to cover your mouth.
“fuck—feel that? how hard i am for you?”
sunghoon rocked forward in shallow thrusts—never quite entering, just gliding along your wet slit, bumping your clit with every pass. the wet sounds were barely audible under the covers, but you could hear them. every slippery slide made your toes curl.
him palm stayed on your mouth before his middle finger deliberately slipped between your lips.
your tongue curled around it instantly, sucking him in like you’d been starving for it. lips sealing tight, you hollowed your cheeks, swirling slow and wet, tasting the faint salt of his skin. his finger pushed deeper, pressing against your tongue, fucking shallowly into your mouth in perfect rhythm with the grind of his hips.
“that’s it,” sunghoon’s breath stuttered against your neck, hissing so quietly at his own arousal. “suck like you mean it, baby. suck it like how you would my cock.”
the words sent a fresh wave of heat through you. you moaned around his fingers—muffled and vibrating down his hand—and he rewarded you by grinding harder, letting the head of his cock drag over your swollen clit.
your hips twitch forward to chase it as you sucked harder, tongue flicking the pad of his fingers like you were trying to make him lose it first. “gosh,” you whimpered as his other hand slid up to cup your tit again, thumb circling your nipple in lazy strokes. he pinched lightly, then harder, until your back arched off the mattress.
“shh, fuck—you’re so loud when you’re trying not to be,” he murmured, nipping the shell of your ear. “gonna come again just from this? humping my dick while sooha’s right here?”
you nodded frantically, eyes squeezed shut in pleasure, thighs clamping around his cock as he kept those torturous glides going. everything coiled tighter, hotter, until you were shaking on the egde.
he felt it. knew it.
his finger pushed deeper into your mouth—hooking and pressing down on the pad of your tongue—while his hips lost its rhythm. now grinding harder, faster, desperate little snaps of thighs that dragged his cock right over your entrance and clit again and again.
“fuck—baby—” he choked out, voice splintering. he buried his face in the crook of your neck, lips parting to kiss and suck and bite—open–mouthed, messy trails along your jaw, down the side of your throat, teeth grazing pulse point. his breathing was ragged, hips stuttering, chasing his own high.
you were both so close—bodies locked together under covers, slick and trembling, wet sounds of skin on skin barely masked by sooha’s breaths on his other side.
just as he was getting close—a soft grunt from behind him. sooha shifted, voice thick with sleep and confusion.
“ngh… sunghoon?”
everything froze.
sunghoon’s hips stilled mid–grind, cock throbbing painfully against you, leaking and rock hard. his finger remained in your mouth, pressed firmly down your tongue. his other arm remained on your tit, while he turned his head just enough toward her.
feigning like he too, just woke up, sunghoon faked a groan. “...yeah?” he answered.
you could feel his heart slamming against your back, how tense his muscles had gone. his cock twitched once, despite the effort not to move. sooha mumbled something incoherent, nuzzling closer into his shoulder, her arm tightening around his waist.
“just… thought i heard something…”
sunghoon let out a soft hum, barely more than a breath. “‘s nothing… go back to sleep, okay?” his middle finger thrusted in and out of your mouth, keeping your mouth busy and full. all while he talked to his girlfriend in that calm, boyfriend voice.
you wanted to laugh.
sooha hummed sleepily, already drifting again, face pressed to his back.
the second her breathing evened out—sunghoon exhaled in your ear. “fuck,” he whispered, so quiet only you could hear. “that was too close.”
but he didn’t pull away. instead, he rocked forward, lips found on your jaw again where he kissed it softer this time. you answered by pushing back harder, thighs tightening around his cock. “mmh—”
sunghoon’s hips snapped forward, his thick length sliding hot and fast along your folds. the wet sounds grew louder under the covers, but neither of you cared anymore. the risk only made it burn hotter.
you moaned into his palm and he groaned low. “fuck—yeah, like that,” he breathed. “my sister’s so fucking wet for me,” he continued, rutting against you like a bitch in heat. his cock throbbed harder, leaking like a faucet, precum and your wetness everywhere.
you’re not that much of a difference too—grinding down shamelessly on your stepbrother, chasing your needs until stars burst behind your eyelids—all while his girlfriend was sleeping on the same bed.
“gonna cum—fuck, i’m so close baby—gonna cum on your thighs,” he rasped, broken gasps against your skin. you nodded, rolling your hips in tight circles. the way the tip of his cock brushed against your sensitive clit was overstimulating—and just like that, it did for both of you.
“mmh—!” your body locked up as you came hard on his cock, pulsing at nothing against his shaft. your cream and slick gushed down your thighs, nails digging into his forearm, back arching, muffled cries against his hand.
sunghoon too, followed right after. “fuck—” he gasped low against your nape, forehead kissing your shoulder blade. his hips stuttered as he spilled ropes of hot and thick semen across the globe of your ass and lower back.
his cum painted your skin under the covers, adding to the warmness. “shiiiit…” he panted, cock jerking with every pulse while he kept grinding on your ass, milking himself against you until he was empty.
his cum smeared on your flesh as his hand eased off your mouth, middle finger slipping out wetly only for him to stroke your cheek inside, thumb brushing your bottom lip.
“good girl,” he whispered, kissing the side of your face. “best sister ever.”
you panted, body limping as sunghoon tugged his sweats and your shorts up carefully, trapping the mess inside. his arms wrapped around you from behind, pulling you flush to his chest—and funnily—clothed cock against your back again.
sooha stayed asleep, oblivious.
“sleep now,” he murmured, kissing the shell of your ear. “next time… we’re going all out.”
