“you’re such an idiot, jonathan,” it was a common sentence uttered from your lips lately, “you don’t even know what we’re arguing about!”
“you’re right, i don’t!” there was a frustrated whine to his voice, as he raked his hands through his hair, “i would never cheat on you-“
“i know you wouldn’t,” you huffed, “i’m not accusing you of doing anything. i’m accusing you of having feelings for someone else, and thinking i’m too stupid to notice!”
“come on, please,” he threw his head back, sighing, “nancy is just a friend, she was there for me a lot with everything with will. it’s not like that, i wouldn’t do that.”
“i told you i know that,” you shook your head, “but i’m not gonna hold you back from what you clearly want, okay? you’re free to do whatever with whoever you please.”
“wait- are you dumping me?” for a moment, you saw a flush of hurt across his face, but it seemed swallowed by an uneasy relief, “babe, come on. seriously.”
“let’s just take a break,” you suggested, not for the first time in your tumultuous relationship, “you can think about what you really want, and i’ll do the same, okay? it’s fine, jonathan, honestly. i’m not angry at you, i just want to figure this out.”
“yeah, okay. fine,” he let out a shaky breath, nodding slowly, “if that’s what you want.”
“it is,” you murmured, “we’ll talk in a couple weeks, okay? i think this’ll be good for both of us. you know i don’t want you to be hurt.”
“yeah, i know,” you could tell he meant it, “see you in 2 weeks, then?”
“2 weeks,” you smiled faintly, “see you then.” it was an odd feeling, the resolution, the relief. you loved jonathan, in a way. he’d been there through so much, even just as a friend, and you wanted nothing but the best for him, even if that best was nancy wheeler. he’d do the same for you, you told yourself, the words assuring you of your decision as you drove home.
what you didn’t expect, though, was to see them together the very next day as you strolled through town, on your way to return books to the library. she was laughing, her face bright in the way it only was around him, and he looked so at ease, so happy, smiling down at her in that shy way he did. they looked good together, you thought. great, even, like it was natural. it had never come that easy for the two of you. you shook the thoughts from your mind, sliding the books into their return slot and turning on your heel, heading back toward your house. as you rounded the street corner, you collided with a wall. no, not a wall, a chest, though it was firm and strong- you looked up, and there was steve harrington, a lopsided grin on his lips and a stray curl on his forehead.
“woah, there,” he laughed, one hand on your shoulder, steadying you, “you alright?”
“fine,” you nodded quickly, unsure why your skin felt so hot beneath his palm, “sorry, i was totally in my own world.”
“don’t worry about it,” he shook his head, letting his touch linger, “you’re y/n, right? byers girlfriend?”
you tried not to be irritated by the association; “yeah. we had science together senior year.”
“oh, i remember,” he laughed again, warm and rich, “you’re like, a complete genius. i would’ve failed if i didn’t get to peak over your shoulder at your notes.”
“you did not!” you gasped, swatting his arm, “that’s awful, steve! i didn’t know i was an accomplice in your cheating.”
“oh, relax. that was forever ago,” he grinned, “what’re you doing out? i saw byers earlier, but he was with nancy.”
you bristled slightly, “i just had to return some books. i wasn’t meeting jonathan.”
“he’s not screwing around on you, is he?” he suddenly looked serious, stern, “i’ll go talk some sense into him, if he is. you just say the word.”
“no, steve, it’s fine,” you shook your head, almost smiling at his sincerity, hesitating before slowly explaining the situation, this break arrangement, jonathan’s infatuation.
“sounds like he is screwing around,” steve said when you were finished, eyeing you cautiously, like he was worried, “but you sound like you don’t care. why not just break up with him?”
“i want him to see this is the right thing,” you shrugged, “it’s complicated, i guess. i’m really not upset, though. you can stop looking at me like that.”
he put his hands up in mock surrender, eyes sparkling, “hey, i wasn’t looking at you like anything. i do have an idea, though.”
“what’s that?” you eyed him suspiciously.
“let me take you out,” he suggested, almost casually, “i mean, if byers gets to run around with nance. it’s only fair, don’t you think?”
“are you flirting with me, steve harrington?” you gasped dramatically, grinning.
“come on, now. who wouldn’t flirt with you?” his voice was softer, sincere, cutting right through the careless charade you’d put on. so, fine, okay. you’d go on a date with steve harrington.
steve, it turns out, was endlessly charming. you knew he could flirt, had seen it time and time again in high school, witnessed the trail of girls he left in his wake, always swooning and swearing he was some sort of god. what you didn’t expect, though, was to become one of those girls yourself, giggling and sharing a milkshake with him, hanging off his every word like it was gospel. it had been a long time since you’d been so relaxed, had such easy fun, let someone charm you. a small part of you felt guilty; it had only been one day, after all. but then you remembered the way jonathan and nancy had looked together, and the months on end that you’d spent with one foot out the door. it hadn’t just been a day, not really. it had been nearly a year of halfhearted affection and forced loyalty. so you pushed it all down, focusing on steve, which felt like the easiest thing in the world when he was so focused on you in return.
“you really are beautiful,” steve’s voice pulled you from your thoughts, and you blinked, slightly startled, “i mean, you were pretty in school, obviously. but you’re gorgeous now.”
“oh,” you flushed, down to your bones, “thank you. i look the same, though, really-“
“don’t do that,” he tsk’d, “let me tell a beautiful girl that she’s beautiful, yeah?” and then he reached across the table, brushing a lock of hair from your face, gentle as anything, “i get why byers was always following you around with that camera. i wish i had one right now.”
you’d never been the spontaneous type. you were methodical, an overthinker, precise and considerate. you weren’t sure, despite all of this, what possessed you to lean over the table and kiss steve harrington. maybe it was the lighting, maybe the way his eyes shined when he looked at you, the way his fingers toyed with the strand of hair as he tucked it behind your ear. you could tell yourself any number of things, but you knew it was only that it was him, that he liked you, that you liked him, that it felt natural, just as it did for nancy and jonathan.
he kissed you back the same way he did everything, easy and sure, right in a way you couldn’t fake. his hand settled on your cheek, cupping your face, pulling you closer despite the diners other occupants. his tongue slid across your bottom lip, and you had to pull away, cheeks hot and lips shining.
“we shouldn’t-“ left your lips, just as he said, “my cars right outside.”
he paid the bill in cash, leaving an excellent tip and pulling you out of the diner in a flurry of movement.
“let me take you somewhere,” he pulled the passenger door open for you, waiting until your legs were tucked safely inside before closing it, sliding across the hood as he went around to his side.
“like where?” you were still buzzing from the kiss, watching his every move, hungry for him.
“just trust me,” shockingly, you found that you did.
his hand settled on your thigh across the console as he drove, the fingers of his free hand tapping the steering wheel along to the music playing quietly from his radio. you drank in the sight of his jawline as he rolled a toothpick from the diner between his teeth, the way the skin of his neck tightened with each motion, his biceps straining against his cotton tee.
“i love this song,” he murmured, i’m on fire by bruce springsteen playing through his speakers. then, something you thought you’d never see; steve harrington was singing along, low in his chest, his thumb rubbing circles on your thigh. “tell me now, baby, is he good to you?” his eyes darted between you and the road, “can he do to you the things that i do?”
there was the unmistakable warmth of wanting, coiled in your stomach, making you shift in the seat of his beamer. the words, the intimacy of the moment, the rasp of his voice, they all washed over you, settled low between your thighs. finally, when you thought it would never ebb, he pulled off onto a side road, driving to the edge of a steep overlook, his car alone with the trees and grassy knolls. beneath you, hawkins was merely a blur of buildings and streetlights.
“this is beautiful,” you said, in awe.
“you’re beautiful,” he was perhaps even more awestruck than you.
you leaned over the console, kissing him again, so grateful for this moment with him. he was rougher now that you were alone, nipping at your bottom lip, hungry and uncaring if it was too fast. it went on for what felt like hours, the slow drag of his mouth against yours, his hands wandering over your body, not yet daring to sneak beneath your clothes. finally, when the wanting was too much, you were awkwardly fumbling into the backseat, giggling breathlessly as you fell into him.
“can i?” he asked, ever the gentleman as he pulled at the hem of your top, eyes shiny and pleading.
“yes, yes of course,” you nodded quickly, helping him free you from it, then pulling off his own. gradually, between kisses, you managed to shed the rest of your clothes, until you were bare except for your underwear.
“you are so beautiful,” he sounded like he was in pain, almost, or in love. you couldn’t tell in the dark, “let me taste you, please.”
you could’ve died and gone to heaven as he slid to his knees in the floorboard, parting your thighs, pushing your slick underwear aside and burying his face between your legs.
“oh my god, steve,” you gasped, hand migrating to his mess of curls, tugging lightly as he lapped at your core, his nose brushing your clit deliciously. he was like a man possessed, right in his element as he watched your reactions, eyes dark with lust. you were practically grinding against his face, eyes rolled back, back arched off the seat.
“please,” you mewled, “fuck, i’m so close. you’re so good, steve.” he was spurred on by your praise, groaning into you, the sound vibrating against your flushed skin. his tongue dipped into you, and you fell apart all at once, fingers tight in his hair, thighs threatening to clamp closed around him.
“so good,” he exhaled as he pulled away, his lips shiny with your slick, “you taste so fucking good.” he perched back over you, kissing you hard and hot, letting you taste yourself on his tongue. you pulled at him, hands on his shoulders, hungry for more, always more.
“please,” you panted between messy kisses, reaching between your bodies, cupping his bulge, nearly moaning at the size and weight of him, “need you to fuck me.”
“yeah?” he grinned at that, cocky as ever, “i can manage that.” he pulled his boxers off with one hand, his other woven through your hair, pulling your head aside to leave your neck open for him to kiss and bite at. you gasped as you felt his tip against your dripping core, teasing your hole, sliding against your puffy clit.
“you’re so wet, baby,” his voice was deeper, raspier, than before, “i don’t have a condom, ‘s that okay?”
“it’s fine,” you nodded quickly, “on the pill.”
he didn’t need anymore encouragement. with that, he pressed into you, agonizingly slow, stretching your walls further with each inch.
“oh, fuck,” you gripped his shoulders tightly, wincing at the burn of the stretch, “you’re so big.”
“you’re almost there,” he murmured, pressing a kiss to your forehead, one hand parting your thighs further, watching as he slid into you.
finally, he bottomed out inside of you, filling you deeper than you ever had been before. you were delirious with the feeling of him, of the way it ached, the way you knew you’d feel him for days after.
“atta girl,” he hissed out, twitching inside you, “can i move now? are you okay?”
“please,” you nodded immediately, “i can take it.” and take it, you did.
he pulled out of you fully before bottoming out once more, stealing all the air from your lungs, drawing a gasp from your lips. one hand made a home on your waist, the other gripping the seat above you, steadying himself effortlessly. you were a mess beneath him in an instant, undoubtedly soaking the car seat beneath you, lewd wet sounds filling the small space.
“you feel so good,” he praised, voice shaking, “fucking perfect, sucking me in. you needed this, didn’t you, baby?”
“mhm!” your jaw was slack as his tip brushed that spot deep within your walls, “needed it so bad, stevie, fuck. you’re so good, so big.”
“knew you did,” he murmured, “did he take care of you? hm? did he take you like this, or could i easily fill his shoes?”
“never like this,” you mewled, “nobody’s ever- nngh, nobody’s felt like this.”
“fuck,” he dropped his head down to kiss you again, messy, spit slicking your chin as he licked into your open mouth greedily. he pounded into you, the car shaking, your thighs trembling right along with it. you squeezed around him as his thumb came down to circle your clit, your back arching from the seat, chest pressing against his.
“come on, baby,” he encouraged, pulling away to kiss your jaw, then trailing down to your throat, “cum on my cock, please? i’m so close, wanna feel you let go.”
“i’m- fuck, oh my god,” you were lost for words, gasping as you came undone, walls spasming around him, shaking in his arms.
“there you go,” he groaned, “oh, fuck, you’re so tight. where d’you want it, baby? hurry.”
“inside,” you whined, hating the idea of him wasting it anywhere else, “it’s okay, please, just want it.”
he kissed you again, slow and tender, as he spilled inside you, warmth flooding your walls, and you shuddered at the feeling, an intimacy you’d never shared even with jonathan.
“my god,” he panted, pulling out slowly, chest heaving, “that was- you’re incredible. you’re okay, right?”
“mhm,” you nodded, blissed out, eyes barely open, but greedily drinking in the sight of him in the afterglow, “perfect, stevie.”
“i like that,” he grinned sheepishly, “stevie. nobody calls me that.”
“that’ll be your new nickname, then,” you murmured fondly, sitting up and wincing at the ache between your thighs, already, “can you help me find my clothes?”
he laughed slightly as he nodded, handing you your ruffled clothes, pulling his own wrinkled tee over his head. after you were both redressed, he just sat there for a moment, looking over at you.
“is this gonna happen again?” he asked softly, almost hesitantly, “or is it over when the breaks over?”
“it was never just going to a break,” you said after a beat, “i’d really like to see you again. maybe not in the back of your car next time, though?”
“i’ll take you wherever you want,” he smiled, “as long as you agree to see me again.”
“you can’t keep me away,” you grinned, leaning over and pressing a kiss to his cheek, “who knew you were such a romantic, stevie?”
“what can i say?” he hummed, “you brought it out of me.”
