a/n - for @decideedjo i hope u like it :))
your mom’s voice on the phone was the usual mix of annoyance and obligation. "your brother is at steve harrington's house. again. you need to go get him. i'm not letting him bike home in the dark."
you sighed, grabbing your keys from the hook by the door. "fine. i'll be back in a bit."
the drive to steve’s house was short, but your stomach was already doing that stupid little flip it always did when you knew you'd see him. you were dustin's older sister, which automatically put you in a weird, sisterly-ish category in his eyes. you'd seen him at a dozen family dinners and school events, watched him morph from “king” steve to… whatever this new, softer version was. the one who carried your brother's d&d books and drove him around. it was an annoyingly attractive transformation.
you knocked on the door, the sound echoing. steve answered, his hair perfectly messy. he was wearing a faded polo and a pair of worn-out jeans, and the sight of him made your mouth go dry.
"hey," he said, his signature lopsided grin in place.
“hey” you managed, your voice a little too high. "is he ready?"
"almost. he's just... uh... finishing a campaign." he stepped aside to let you in. the house smelled like him—clean laundry and a hint of cologne. "wanna wait? he'll be like, five minutes. max."
you nodded, stepping into the familiar warmth of his house. you followed him into the living room, trying not to stare at the way his shirt stretched across his shoulders. he plopped down onto the couch, patting the spot next to him. you sat, leaving a careful foot of space between you.
"so," he started, grabbing the remote and flicking through the channels. "how's... uh... school?"
"good," you said. "it's school."
the silence stretched, thick and awkward. you could hear the faint, dramatic sounds of dice rolling and dustin and ushouting from the basement. five minutes, my ass.
"you wanna watch something?" he asked, landing on some cheesy horror movie.
he leaned back, slinging an arm along the back of the couch behind you. it was a casual move, but it felt anything but. you could feel the heat from his arm, a phantom touch against your shoulders. you tried to focus on the screen, on the screaming girl running through the woods, but all you were aware of was him. the way he breathed, the way he shifted, the way his fingers occasionally brushed against your shoulder.
you must have been more tired than you thought, because you started to drift, your head lolling to the side. it gently came to rest on his shoulder. you froze, expecting him to stiffen or move away. he didn't. instead, he relaxed, his arm coming down from the back of the couch to wrap around your shoulders, pulling you closer. you melted against him, the tension leaving your body in a rush. this felt better. this felt right.
you must have actually fallen asleep, because the next thing you knew, you were being gently shaken. you blinked your eyes open, disoriented. you were curled up against steve's side, his hand resting on your hip, the movie credits rolling silently on the screen.
"hey," he said softly. "dustin's ready."
"oh," you said, sitting up quickly, your face flushing with embarrassment. "shit. sorry. i didn't mean to..."
"it's okay," he said, his voice gentle. "you looked tired."
dustin came bounding up the stairs, his backpack slung over his shoulder. "finally! we totally wiped the floor with the demogorgon. mike was a terrible barbarian, but he got a lucky shot in."
"hey!" mike protested, but there was no heat in it.
you stood up, your legs a little shaky. "alright, let's go, dustin."
as you headed for the door, steve caught your arm. "hey, wait a sec."
dustin groaned, rolling his eyes. "i'll be in the car. don't be gross." him and the party stomped outside, leaving you alone with steve.
the air crackled. the awkwardness from earlier was gone, replaced by something thick and heavy with anticipation.
"so..." he started, rubbing the back of his neck.
"so…" you repeated, your voice barely a whisper.
you looked up at him, your heart hammering against your ribs. he took that as an invitation. he leaned down and kissed you.
it was soft at first, a gentle press of his lips against yours. it was everything you'd secretly dreamed about and more. you sighed into his mouth, your hands coming up to rest on his chest. the kiss deepened, growing more urgent, more desperate. his arms wrapped around your waist, pulling you flush against him. you could feel him, hard and wanting, pressing against your stomach.
he broke the kiss, resting his forehead against yours. "dustin's gonna be waiting," he murmured, but he made no move to let you go.
"he can wait a little longer," you breathed.
that was all it took. his mouth was back on yours, fierce and hungry. he backed you up against the wall, his body pinning yours. his hands were everywhere, sliding down your back, cupping your ass, pulling you closer. you tangled your hands in his hair, holding him to you as if you were afraid he'd disappear.
his lips left yours, trailing a hot path down your neck. he nipped at your skin, sending shivers down your spine. "you have no idea how long i've wanted to do this," he groaned, his voice rough with desire.
"me too," you admitted, your voice breathless.
his hands fumbled with the button of your jeans, his fingers clumsy with haste. he popped it open, his hand delving inside, past the barrier of your underwear. you gasped as his fingers found you, hot and slick. he stroked you once, twice, a slow, deliberate exploration that made your knees weak.
"steve," you whimpered, your head falling back against the wall.
he sank to his knees in front of you, his eyes dark and hungry. he tugged your jeans and panties down in one fluid motion. you stepped out of them, kicking them aside. he looked up at you from his position on the floor, a look of pure reverence on his face, before leaning in and pressing his mouth to you.
you cried out, your hands flying to his shoulders to steady yourself. his tongue was magic, flicking and circling your clit with a precision that had you seeing stars. he held you hips, his grip firm, as he devoured you, his movements growing more frantic as your moans grew louder. the pleasure built, a tight, hot coil in your stomach, and when he slid a finger inside you, curling it upwards, the coil snapped.
the orgasm ripped through you, a blinding, all-consuming wave of pleasure that made your entire body tremble. you cried out his name, your hips bucking against his face as you rode out the intense release.
he didn't stop, easing you through it until you were a boneless, panting mess. he stood up, wiping his mouth with the back of his hand. he picked you up as if you weighed nothing, your legs wrapping around his waist. he carried you to the couch, laying you down gently.
he quickly shed his own clothes, his eyes never leaving yours. he rolled on a condom he pulled from his wallet—of course he had one in his wallet—and then he was over you, settling between your legs.
he positioned himself at your entrance, his eyes locking with yours. "are you sure?"
you answered by wrapping your legs around his hips, pulling him down. he pushed into you in one slow, deep thrust that made you both groan. he filled you completely, a perfect, stretching fullness that you hadn't realized you were craving.
he started to move, setting a slow, deep rhythm that was somehow more intimate than the frantic moments before. he propped himself up on his elbows, his forehead resting against yours, his eyes locked on yours as he moved inside you. the couch springs groaned in time with his thrusts, the only sound in the room besides your heavy breathing.
"you feel so good," he whispered, his voice strained. "so fucking good."
you wrapped your arms around his neck, pulling him down for a kiss. it was a slow, messy kiss, full of tongue and teeth and unspoken feelings. the pace quickened, his thrusts becoming harder, deeper. he was hitting that perfect spot inside you, over and over, and you could feel another orgasm building.
"steve," you gasped against his lips. "i'm close."
"come for me," he grunted, his rhythm becoming erratic. "come with me."
his words sent you over the edge. you came with a cry, your inner walls clamping down around him as pleasure washed over you. he followed you a moment later, his hips stuttering as he found his own release, burying his face in your neck with a low groan.
you lay tangled together on the couch, your bodies slick with sweat, the movie long forgotten.
