heat my engine harder

Summary:

“You’ve got such pretty thighs, hyung,” Changkyun had said earlier, emboldened by the cognac and their hot, sloppy kissing. “Makes me want to sit on them.”

A night in Changkyun's studio. Changkyun likes to be spoiled, and Jooheon lives to spoil him.

Notes:

So I've had this fic lying around half-finished since like....September? Figured I'd finally slap and ending on it and publish it so I can work on a few other things. Unbeta-d, which means that I'm going to come back and fix all typos in like, a week probably. Also, this is set around Love promotions, hence the blonde hair.

Also, heads up: please please please pay careful attention to these tags and ensure that it's something you're comfortable consuming! In this fic, Changkyun is a trans man and is referred to exclusively as he/him, but parts of his body are going to have "gendered" language ("cunt," "pussy," etc.). I'm not going to apologize for what I find enjoyable to write or read, but if these things are distressing to you, please put your comfort first and don't engage with a fic that may upset you.

Title from "Overdrive" because I feel like I legally had to.

(See the end of the work for more notes.)

Work Text:

This always happens when he’s drinking with Changkyun.

Well. Not that it only happens when they’re drinking; Jooheon still has the bite marks on his inner thighs from a few days ago, when Changkyun pounced on him right after a schedule. But when they drink together, it’s as good as a guarantee that they’re going to mess around.

“Come by my studio after this,” Changkyun had whispered in his ear, mid-rehearsal. His eyes had been covered by the brim of his hat, but Jooheon’s stomach flipped anyway, imagining the heat he may have found in his gaze. “Let’s get a beer or two.”

But naturally, a beer or two became shots on the couch became Changkyun sucking the taste of liquor out of Jooheon’s mouth, all of which have led them here. It always does.

They’re on the plush leather couch in the studio, and Changkyun is naked from the waist down, stradling one of Jooheon’s thighs. He’s still got a thin black undershirt on, rucked up to show the flex of his abs as he grinds himself against Jooheon’s leg. Jooheon himself is only wearing his boxer briefs, flushed skin beading with sweat and sticking to the leather couch.

Jooheon trails his fingers along the hem of Changkyun’s shirt, watches as color floods his cheeks. His dark eyes are hazy as he loses himself in sensation, fluttering closed as he works himself over Jooheon. He’s beautiful like this, Jooheon thinks. He wants to see even more.

Jooheon tugs on the shirt again. “Take this off, baby,” he says gently.

With a breathy little sound, Changkyun does. The flex of his shoulders as he rips the shirt off is a beautiful thing to watch. The shirt falls forgotten to the floor. Changkyun’s nipples are already peaked. Satisfied, Jooheon leans in close to Changkyun’s chest, flicks his tongue against a nipple.

Changkyun isn’t particularly vocal during sex, or at least not at the start, but he’s huffing these little noises out as he rides Jooheon’s thigh, small puffs of air between his lips that he can’t control. His breathing hitches even more when Jooheon purses his lips to suck on that same nipple. Changkyun’s fingers dig into Jooheon’s shoulder, keeping him close to his chest, still chasing friction with every grind of his hips.

Jooheon’s hand cups Changkyun’s ass, drags him closer against his thigh. Changkyun gasps for it. “That’s it, baby,” Jooheon purrs before switching his ministrations to the other nipple. His cock twitches in his boxer briefs, but his eyes are fixed on Changkyun’s face contorting in pleasure, trying and failing to stifle his little noises as his clit rubs harder against Jooheon’s thigh.

Eyes downcast, Changkyun starts to work his hips in a faster, more erratic pace. Groaning, he leans forward against Jooheon, panting hot and heavy into the cook of Jooheon’s neck and shoulder. The aircon is on, but the room still feels so warm, air heavy.

“Chase it,” Jooheon whispers to him, enraptured. His hand slips into Changkyun’s blonde hair, the roots already damp with sweat.

Jooheon decides to help him out. His other hand slips between his body and Changkyun’s, fingers poised to circle Changkyun’s clit. But to his surprise, Changkyun bats his hand away. Jooheon turns his head, blinking in confusion.

“Nnnnnnnnnn, no,” Changkyun pants, voice muffled against Jooheon’s neck. The sound of his voice is wet, slurred from the alcohol. His tongue darts out to lick at the sweat on Jooheon’s throat, and Jooheon shivers. “I wanna come like this.”

Shit. Changkyun’s cunt is still wetly dragging against Jooheon’s thigh, back and forth, in quick, jerky pulses. Jooheon can’t pretend that he isn’t more than a little turned on at the idea of being used like this, like he’s just a fucktoy for Changkyun to rub himself again.

“Okay, baby,” Jooheon whispers. The rasp of his voice makes Changkyun bite down on a whine, knuckles white as he grabs onto Jooheon’s shoulders and hangs on for dear life. Jooheon’s thigh is soaked from his slick, getting wetter with every pass of Chagkyun’s hips. As Changkyun moves, his knee rubs against Jooheon’s erection, and it takes all of Jooheon’s self-control not to drag Changkyun farther up to push their hips together, fuck against him properly. But Changkyun had already said he didn’t want that tonight.

“You’ve got such pretty thighs, hyung,” Changkyun had said earlier, emboldened by the cognac and their hot, sloppy kissing. “Makes me want to sit on them.”

Jooheon is more than happy to wait his turn.

He tenses his thigh, gently rucks up against Changkyun’s cunt. Changkyun groans, long and loud. “Fuck, hyung,” he pants, shoulders shaking. “Do that again.”

Jooheon does. He keeps the muscle of his thigh tense, rocking up again to meet the force of Changkyun’s hips. Changkyun’s answering moan is loud and unabashed, like he only ever gets when he’s really far gone. Thank god for the studio’s soundproofing. “Fuck,” Changkyun whines, hips moving with more urgency. His fingers are going to leave bruises, the way they’re digging into Jooheon’s shoulders. “‘m getting close.”

Jooheon flicks Changkyun’s nipple with a finger, watches as Changkyun’s brow furrows in pleasure. They’re moving together on the couch, Jooheon fucking his thigh up against Changkyun’s cunt, Changkyun doing his best to hold on for the ride. His hips start stuttering, faltering in their rhythm. Jooheon watches as Changkyun’s body draws tight, inching towards climax.

“Good boy,” Jooheon whispers, voice pitched deep and gravelly. “You can come whenever you want. Hyung wants you to come.”

Changkyun keens, buries his face against Jooheon’s face as he comes. Arousal is circling low in Jooheon’s gut from the sound of it, the feeling of Changkyun quivering against him. He wishes he could see his face. The force of his orgasm makes Changkyun’s shoulders quake, knees wobbling where they’re braced on the couch. Jooheon gathers Changkyun into his arms, gentle and indulgent.

“So good, baby,” Jooheon says, pressing kisses to Changkyun’s ear, his forehead, the hinge of his jaw, anywhere he can reach. His heart pounds wildly in his chest, feeling overwhelmed by affection. That Changkyun gives himself over like this to him is something Jooheon will never truly get over. He kisses the arch of Changkyun’s eyebrow for good measure, heart fluttering in his throat. “You’re so fucking good for me. Love watching you come like that.”

Changkyun draws back with a small, shaky smile, just the tiniest upwards quirk of his lips. It sends Jooheon’s heart soaring regardless. He’s glancing at Jooheon under his dark lashes. There’s genuine pride there in his eyes, all from Jooheon’s praise.

But there’s also something else, something darker, like desire. Like he wants Jooheon to push him just a bit further.

Jooheon can give that to him.

As soon as Changkyun clambers off of Jooheon’s thigh, he lies back with his legs splayed. Jooheon crowds into his space, reaches between them and slaps Changkyun’s cunt.

Changkyun immediately whines for it, body trembling from shock and oversensitivity, but when he opens his mouth, he just says, “Again.”

Jooheon smacks his cunt again, palm coming away sticky as Changkyun sobs. But he’s holding his thighs open for Jooheon to spank him again, body trembling with embarrassed, overwhelmed pleasure. He likes the oversensitivity, he’d explained to Jooheon years ago, a night that he’d begged Jooheon to eat him out after he’d been fucked, until he was literally crying. Jooheon had to stuff a shirt in his mouth so he wouldn’t alert the other members what they were up to behind closed doors. (He isn’t sure they were successful, Kihyun refused to look their way for at least half a week.) Changkyun sometimes likes to feel small and helpless sometimes, he likes it when it hurts. Something about how it gets him out of his head sometimes.

Jooheon hadn’t quite understood what he meant back then, but now, he can read Changkyun so well that he knows when he’s begging for more. Begging to be pushed even harder.

With a final wet slap, Jooheon leans in and pressed a quick kiss to Changkyun’s open mouth. “Love you,” he whispers.

“Love you too, hyung,” Changkyun replies in a shaky voice. But there’s that tiny smile again, and damn, if that doesn’t strike Jooheon dumb every single time.

Still in his boxers, Jooheon settles between Changkyun’s legs. His palms press against Chagkyun’s thighs, pinning them apart. He takes his time dragging soft, open-mouthed kisses across the expanse of one thigh. Changkyun’s body is firm with muscle, but here in his inner thighs, he’s still soft, almost plush. Jooheon bites against the give of that soft skin, and the choked-off curse that Changkyun makes for him in response settles over him like a heady wave. Changkyun is still so fucking wet, slick still painting his inner thighs from earlier, and Jooheon laps it up greedily.

Satisfied that this first thigh has been given enough attention, Jooheon shifts to start on the second, smirking when Changkyun whines again. His kisses inch up Changkyun’s thigh, so close to where he knows Changkyun wants him, but not close enough to touch. Making Changkyun wait is satisfying all on its own. He loves when Changkyun finally gets restless enough to make demands. Like now, when Jooheon is sucking a dark bruise into Changkyun’s skin, and impatient, Changkyun fucks his hips forward, wet cunt grazing Jooheon’s jaw and leaving a sticky smear.

Jooheon chuckles to himself. This is exactly what he wanted, exactly what he knows Changkyun wants. “Thought you were gonna be patient for me, baby,” he says, dropping another kiss to the bruise he left in Changkyun’s thigh.

“Getting sick of waiting for you, hyung,” Changkyun pouts in a small, raspy voice, but still clearly exaggerated. It’s probably not good or healthy that all of Changkyun’s affected brattiness is going straight to Jooheon’s cock, makes him want to rub himself off against the leather couch cushions, but that’s neither here nor there. Changkyun’s flush deepens. “Go ahead and do it already.”

Jooheon leans up to trace his fingers high up on Changkyun’s thigh, so close to Changkyun’s outer labia but not yet touching. He can barely hear Changkyun’s whine, watches him squirm in frustration. “But I wanna hear you ask me, baby,” Jooheon says, because this? This is part of pushing him. Changkyun has begged him for this before, has told him how he loves being forced to say his desires out loud, like the control is being wrestled from him and he’s helpless but to beg. He craves it.

Jooheon is nothing but obliging.

Changkyun’s whining again in hesitation and mock-hestiance, but Jooheon presses on. He doesn’t miss Changkyun’s little shiver beneath him. “Tell me what you want,” he says, fingers forming a V shape, pushing Changkyun’s outer labia apart and leaving him exposed, pink and soft and wet. “Or I stop touching you right now and go home.”

They both know it’s a bluff. Jooheon is too romantic, too doting to ever really leave Changkyun hanging, but the game is what’s important. Changkyun’s next words come out in a tumbled rush. “Want you to eat me out, hyung,” he begs in a small voice.

Jooheon smirks. Changkyun’s not quite where he wants to be yet, he can tell. One more push. “Be specific, baby.”

The full-body shudder that Changkyun gives him goes straight to his cock. “Want you to eat my cunt,” Changkyun babbles. “Want your mouth on my pussy, please, hyung, want it so bad.”

Changkyun’s words crash over Jooheon like a falling wave. “Good boy,” he rasps, and lowers his mouth to Changkyun’s cunt.

Changkyun wails as Jooheon laps at him, drawing his tongue up between his folds to circle around his clit. Jooheon groans at the taste of him, thick and sweet. He feels Changkyun’s hips twitch against him, trying valiantly to ride his face, but Jooheon slides his hands up to grab Changkyun’s hips, keeping him pinned in place. Jooheon can barely hear Changkyun’s soft little gasps over the wet, sucking sounds of his mouth on Changkyun’s cunt. He draws the flat of his tongue over Changkyun in long, broad strokes, before focusing the tip on Changkyun’s clit again, flicking it and working Changkyun into a frenzy.

Jooheon pulls back for a scant moment to gather his breath. Spit and Changkyun’s slick are smeared all over his mouth and chin. “You taste so fucking good, baby,” he breathes, before diving back down to suck Changkyun’s clit in his mouth. Changkyun keens, hitches one leg over Jooheon’s shoulder to keep him close. The heel of his foot digs into Jooheon’s back, making Jooheon groan. His soft, pink skin flutters against Jooheon’s tongue. Jooheon knows he’s close. After Changkyun’s first orgasm, his next always follows quickly after.

Changkyun’s groaning deep in his chest as Jooheon eats him out, the sound growing louder as Jooheon’s tongue circles steadily around his clit. Jooheon gives a groan of his own, overwhelmed by the smell, the taste. He could happily spend hours between Changkyun’s thighs, and has before, content to lap at Changkyun’s cunt until his jaw goes numb. His eyes are closed as he works his mouth over Changkyun’s pussy, but he feels Changkyun’s hand reach up to smooth over his forehead, fingertips then tangling in Jooheon’s sweaty hair. Changkyun doesn’t have much leverage with his hips, the way Jooheon is pinning him down, but with his hand, he pulls Jooheon closer by the hair, nearly suffocating him in his cunt. Jooheon moans again, rocking his own hips downward against the couch cushions, stiff cock begging for friction. He honestly thinks he could come like this — overwhelmed by the sting of Changkyun’s hand in his hair, the taste of Changkyun on his tongue, the desperate noises that are escaping Changkyun’s mouth, the rough friction of his cock humping into the couch cushion. But Changkyun comes first. Changkyun always comes first.

Jooheon’s mouth is merciless now, the tip of his tongue flicking over Changkyun’s clit over and over. His head bobs with the motion, jaw tensing with strain. Changkyun’s fingers tighten in Jooheon’s hair, body going taut underneath him. “Fuck, hyung,” Changkyun breathes, just loud enough for Jooheon to hear over the wet noise of his mouth. Spit and slick are dripping onto the couch cushions below them. Changkyun’s inner thighs are drenched. “I’m, I’m gonna come again,” Changkyun whines, fingers flexing in Jooheon’s hair as his thighs tense.

Arousal makes Jooheon’s knees go weak, hot and overwhelming like molten gold dripping down his spine. He doesn’t say anything, just licks and sucks at Changkyun’s clit until Changkyun gives him one last cry and comes. Jooheon laps up his slick greedily with a moan, the taste and the feel of his shivering skin almost enough to trigger his own climax. Changkyun tries to push Jooheon away but Jooheon clings to him tightly with a growl, tongue still working over him through the crest of his orgasm. Changkyun’s answering cry is loud, overwhelmed, hips twitching to get away from Jooheon’s mouth while at the same time inching forward as much as he can, like the brand of Jooheon’s hot tongue against his cunt is rooting him to the spot. His oversensitive cunt quivers against Jooheon’s mouth, and his moans are drawn-out, completely undone by sensation. Too much, too good. Exactly how Jooheon knows he likes it.

When the shivering aftershocks stop, Jooheon draws back. He takes a second to regard Changkyun below him, drinking in the mess he’s made. Changkyun is still breathless, chest all flushed and damp with sweat. His legs are spread wide apart, inner thighs sloppy wet from slick and Jooheon’s spit. He looks wrecked, and more beautiful than anyone Jooheon has ever seen in his life. With a small, desperate noise, Changkyun reels Jooheon in, crushing their lips together. Jooheon groans. His mouth is slack from earlier, but Changkyun doesn’t seem to care, lapping up the taste of himself from Jooheon’s lips and tongue, moaning when their tongues slide together.

Another wet, smacking kiss. Changkyun draws back a scant inch, finally cups one hand against Jooheon’s still-covered cock and making him moan. Their mouths brush against each other when Changkyun begs, “Fuck me.”

Jooheon doesn’t have to be told twice. He draws himself up on his knees, and with shaking fingers, slides his boxer briefs down his hips. He kicks them off, never breaking eye contact with Changkyun’s heavy gaze. His flushed cockhead is already smeared with come, he nearly jumps when he reaches to take himself in hand, so sensitive already and desperate for touch. Changkyun watches the way his hand moves on himself hungrily, color high on his cheeks.

Jooheon leans in again, heart jackhammering in his chest. Changkyun drags him down for another fervent kiss, groans against his mouth when Jooheon’s cockhead slips against the wetness between his legs.

Jooheon’s pulse is racing. “Turn over for me,” Jooheon whispers in his ears, his lips dragging against Changkyun’s earlobe. He delights in the shudder that Changkyun gives him in response, heart galloping as Changkyun scrambles to flip himself over. Changkyun’s elbows are braced against the arm of the couch now, back arching, his generous ass on display. Jooheon can’t help but give that ass a squeeze, reveling in the way that his handprint blooms across Changkyun’s skin. He has half a mind to take himself in hand, jack himself off and cover that perfect ass in his come.

Changkyun’s voice breaks him out of his reverie. “Fuck me,” Changkyun repeats, voice quiet and raspy as Jooheon settles behind him. His cockhead slips against Changkyun’s cunt again, and it takes everything that Jooheon has not to come on the spot. “Fuck me, fuck me, fuck me.”

With a groan, Jooheon pushes inside. Fuck, but Changkyun’s pussy is perfect: hot, tight, slippery wet, puffy lips practically kissing Jooheon’s cockhead before he sinks deeper inside. When he bottoms out, he can feel the wetness of Changkyun’s slick and the remnants of his own saliva smeared around the base of his cock. Changkyun’s giving him these little whines as Jooheon holds himself still, giving Changkyun a moment to get used to the stretch.

But of course, that’s not what Changkyun wants. “Fuck me, hyung,” he begs, the words falling from his panting lips. “Please, give it to me hard.”

Shit. Jooheon can do that.

Jooheon wraps an arm around Changkyun’s chest, his other hand splayed out next to Changkyun’s to brace himself on the arm of the couch. He draws his hips back a few scant inches then slams himself back inside. Changkyun makes a choked gasping sound when Jooheon does it again, setting a fast, brutal rhythm. Fuck, Jooheon’s not going to last long. Changkyun is so hot and tight around him, the slippery friction of his cunt so agonizingly perfect that Jooheon is already so close to snapping. Jooheon’s chest presses against Changkyun’s back, their sweat sticking them together despite the aircon whirring on overhead. Like this, Jooheon only knows the hot clench of Changkyun’s cunt, the breathy sound of his cries, the sticky slap of skin on skin.

Lust spikes in Jooheon’s stomach, his body drawing tight. With every frantic fuck of his hips, he feels himself pitched closer and closer to climax. He’s sure Changkyun can feel it too, the erratic way Changkyun’s hips are humping back against him, meeting him thrust for thrust. He’s chanting “hyung, hyung, hyung” under his breath as he pushes back against Jooheon’s hips, eyes closed and mouth slack. Jooheon’s fingers pluck at Changkyun’s nipple, drawing out a pained little gasp. The way Changkyun’s cunt clenches for it makes Jooheon moan loud, unabashed, heavy cock twitching inside of Changkyun. His fingers move to twist Changkyun’s nipple again, make Changkyun’s cunt spasm around him again.

It’s too much. “Coming,” Jooheon gasps, pressing the sound against Changkyun’s shoulder blade. He makes it one, two more hot thrusts before the tension snaps, climax sweeping him away in a heavy tide. His cock is buried deep in Changkyun’s cunt, hot come spilling deep inside his body. Changkyun groans for the sensation, his hips still twitching backwards, like he wants to be stuffed full of Jooheon’s come, like he wants to plug himself up. Jooheon watches as Changkyun’s hand moves downwards off the armrest, making to rub himself off.

Jooheon beats him to it. Slipping his hand from Changkyun’s chest, Jooheon reaches down to finger his puffy cunt. His fingers draw through slick wetness to touch the place where they’re joined, and then circle around Changkyun’s clit feverishly. Changkyun’s sweet cries are achingly beautiful, Jooheon’s heart hammers for the sound of them. The way Changkyun’s pussy throbs around his spent cock is too much, sweet on the side of painful, but he drags his fingertips in tight little circles over Changkyun’s clit anyway, savoring the way Changkyun’s moans pitch deeper, louder.

He can feel it when Changkyun comes, shuddering around him with a sharp gasp. Changkyun’s whole body shivers with it, shaky noises passing his slack lips in aborted little puffs of breath. Jooheon’s heartbeat is still racing. He leans in to press a tender kiss against Changkyun’s earlobe. “You’re so good,” he breathes, nuzzling close against the side of Changkyun’s face.

Jooheon can feel more than see the way Changkyun’s lips turn up in a small smile. “You too, hyung,” he breathes.

Loath though he is to end this soft moment, Jooheon draws back. His cock slips out of Changkyun with ease, and he watches with no small amount of interest as his come starts to drip out of Changkyun’s cunt. The cushions underneath them are filthy, drenched with slick, come, and god knows what else. “This couch of yours is ruined, Changkyun-ah,” Jooheon says as Changkyun turns around.

Changkyun’s already collapsed back against the armrest. Blonde hair sticks to his sweaty forehead. Jooheon thinks he looks beautifully disheveled, and it brings him no small amount of pride that he’s the one who gets to see Changkyun like this. That all of this is just for him.

“I’m probably gonna have to get a new one,” Changkyun admits. He passes a hand over his face contemplatively. “There’s only so many stains that come out of leather.”

Jooheon purses his lips. “You could get it professionally cleaned.”

Changkyun just gives him a look. Jooheon assents. “Okay, maybe new couch it is.”

Changkyun’s snicker to himself is a quiet thing. He loops his arms around Jooheon and pulls him down, cradling Jooheon close to him. Jooheon’s heart soars, settling himself around Changkyun so Changkyun can pillow his head on Jooheon’s chest. Despite how filthy they are, Changkyun’s love of spooning after they fuck will never get old.

“You know,” Changkyun starts. Jooheon quirks up an eyebrow. His fingertips are absently tracing patterns across Changkyun’s hip. “You could help me pick out a new couch tomorrow.”

Jooheon’s brow furrows. “You want me to go furniture shopping with you?” he asks. It’s meant to sound stern, but he can’t keep the smile out of his voice. Of course Changkyun would rope him into doing this, too. Of course he knows that Jooheon would do anything he asks.

“Just a thought,” Changkyun says, nuzzling into Jooheon’s shoulder. “It’s not like you say no to me a whole lot.”

“You absolute little brat,” Jooheon teases, delighted. He reaches up to pinch Changkyun’s cheek, making him laugh. “I spoil you too much.” But he can’t wipe the smile off his face. His heart is too full to think of anything but how beautiful Changkyun looks like this, held close in his arms, how he’d gladly give the world for him.

Changkyun huffs a quiet little laugh against his skin, utterly fond. It sounds like the most beautiful thing Jooheon has ever heard. “You like it, hyung,” he says.

Yeah. Jooheon really does.
