Work Text:
This is not Chenle’s first rut, obviously, but it’s his first rut with Donghyuck.
It hits them both by surprise, really. He’s usually pretty okay about keeping track of it, but the company’s been busy, he’s been busy with the whole new facets of their relationship, it kind of just snuck up on them.
Partly because it’s different from any other rut before. Usually his ruts are a nuisance at best, and a punishment from God at worst. He can still feel that familiar, buzzing energy under too-tight skin, but weirdly, it’s subdued. He’s too busy thinking about Donghyuck to really feel it.
He does that a lot, think about Donghyuck. He always had, he came to realize a few weeks before that first official date, felt it deep in his bones when he knew Donghyuck was home alone, in pain, suffering his heat alone, and Chenle couldn’t even breathe without having him at the forefront of his mind.
This though, is a bit obsessive. “I need to be put in a mental institution.”
Renjun, to his credit, remains unimpressed. That’s pretty much his default response to anything Chenle ever brings up to him, but it goes to show how gone Chenle is when Renjun’s raised brow —perfectly manicured, laminated just a week ago— doesn’t spark his usual antagonism.
“You’re horny,” Renjun tells him, dropping his judgmental pretty eyes to his computer, managing to type and insult Chenle at the same time. “What you need is to be sedated.”
And Chenle can’t even disagree out of spite, because it’s awfully true. “Yeah,” he agrees instead. “So you’ll cover for him, right?”
Donghyuck is standing by the copy machine, talking to Sungchan, and Chenle is trying his best to use Renjun as a distraction, anything to avoid being a knot-headed alpha asshole or whatever.
He only spares a glance at Renjun, long enough to see him roll his eyes, before he goes back to staring at Donghyuck. He knows he’s talking to Sungchan about a project he will leave hanging to go spend Chenle’s stupid rut together, but goddammit, who even needs to be that tall? Anything over 5’11 is just bragging.
“Dude, relax, you’re stinking the place up,” Renjun hisses at him, before dropping his shoulders in a sigh that is reluctantly fond, Chenle is happy to note. “Of course I’ll help, it’s honestly insulting you have to ask, but I’ll give you a pass.”
Donghyuck giggles at something Sungchan says. Straight up giggles. The hair at the back of Chenle’s neck stands up straight, and he decides he has won the right to be a knot-headed alpha asshole.
“Thanks, see you,” he rushes out, continuing to stink up the place because what the fuck. What the fuck.
Like he said, different. Familiar buzzing under his skin, the itch he simply can’t scratch and the heightening of his senses to the point it almost hurts. Except, he has a Donghyuck- shaped tunnel vision at the moment, and instinct overwhelms any rationality he might possess.
“Hyuck,” he calls as he approaches, barely sparing a nod in Sungchan’s direction before turning back to his boyfriend. “Ready to go?”
Donghyuck is adorably ruffled today; in the rush of Chenle letting him know what was happening, talking to HR, instructing his coworkers on how to proceed in his absence, and making sure they have all they’ll need, Donghyuck ended up sweaty, blue button down shirt untucked, and his hair a slicked back mess.
He waits for a sense of… urgency, he supposes. Some animalistic need to claim him, audience be damned, to take him right there with the sole purpose of… owning him. And instead, warm enough to make the blood in his veins burn, Chenle feels something he’s never associated with his ruts: security.
Safe, like his Alpha knows everything is alright, because Donghyuck is there. With him, for him.
He’s still jealous, obviously. He has exploded Sungchan with his mind in seven different ways.
“Yeah, let me just—,” he watches, maybe more intently than needed, as Donghyuck checks his rucksack, pats his pocket. To Sungchan he says, “If you need anything, just text. Good luck!”
And then he turns to Chenle, and everything quiets down. Nothing in focus but Donghyuck golden skin, his moles, his heart shaped mouth and his bright eyes.
“Let’s go home.”
“I’m sorry, just…”
Even at home, it all feels weird. Not bad, just different. He’d thought that as soon as they were in the privacy of Chenle’s apartment, he’d ravish Donghyuck while muttering crazy shit like let’s have babies and let’s get married and enjoy tax benefits.
Instead he has Donghyuck pinned to the kitchen floor, rubbing his cheeks everywhere.
He keeps mumbling I’m sorry, even as Donghyuck shushes him, tells him it’s fine. He’d stripped Donghyuck so fast he’d ripped the fabric of his clothes, and the wooden floors are hard and cold beneath them, and yet Chenle can’t seem to move, too drunk on Donghyuck’s scent. Rich cinnamon and sweet tangerines, a smell that feels like coming home from a harsh winter, as familiar to him as Chenle’s own.
And he keeps rubbing his own thunderstorm musk on every inch of burning skin he can reach, rubbing until his skin feels raw, and even that’s not enough.
He’s beside himself when he starts licking at Donghyuck’s cheek. He knows it’s not him, not really, it’s that baser instinct that not even evolution has managed to rid them off. Donghyuck is safe, safe underneath Chenle’s branding hands, safe under his touch and his smell and their home, their space, where Donghyuck has three drawers, favorite cutlery, his best dad coffee mug and pink toothbrush.
Donghyuck doesn’t even say anything as Chenle moves from his face, down to his neck and the protruding bones of his collarbones. He can feel himself growing hard in his slacks —that, surprisingly, had taken a while to kick in, probably one of the main reasons he didn’t realize he was rutting. But as he moves to lave his tongue on Donghyuck’s armpit, where it tastes salty and smells heavy, he feels his cock fattening up so fast he grows dizzy for a second.
And Donghyuck just lets him, gasps the most delicate noises he’s ever heard as Chenle continues to leave his sticky saliva everywhere he can reach.
“I just…” Chenle starts as he reaches Donghyuck’s bellybutton, pausing right where his cock is hard and wet at the tip, tries to put into words how he’s feeling, what he’s even trying to achieve here by scenting Donghyuck so aggressively, but he can’t. “You smell so good, and I like you so much.”
He says it like it should make sense, and maybe it does, or maybe Donghyuck likes him enough to get it. He just nods, cupping Chenle’s jaw with a trembling hand. His eyes keep fleeting all over Chenle’s face, and he can only wonder how he looks right now to put such wonder in Donghyuck’s eyes before continuing with his path.
He ignores Donghyuck’s cock altogether, moves down to his thighs instead. He has lovely legs, long and soft, strong yet giving. Chenle starts licking him all over again, before getting easily distracted by the taunting smell of his slick.
He grips his knees to pull his legs further apart, wide so he can take a good look at his puckered hole. He’s wet, partly Chenle’s pheromones, but mostly just them, making the inside of his thighs shiny.
“I’m going to eat you out now.”
He hears himself informing him, rather drily, like announcing the weather, and Donghyuck only has enough time to make a questioning sound before Chenle’s putting his thighs over his shoulders and burying his face between his legs.
Donghyuck tastes good; sweet, something light and airy, and Chenle presses his tongue against his entrance and takes, takes, takes. Donghyuck is making all these gorgeous, desperate sounds, mewling and whimpering, calling Chenle’s name with the same reverence one uses to chant a hymn. Usually his ruts have always been about fucking himself deep into whatever, whoever, he could, and he knows that part of him is coming, but as he continues to fuck Donghyuck with his tongue, nothing could be more important than this: making his Omega come, with his name on his tongue and his body aching for him.
It doesn’t take much to have Donghyuck spurting all over his tummy; a hint of teeth on his rim and he’s groaning, a wordless sound that tapers off into a breathless moan as his whole body tightens, his scent so invasive around the room, tinging the very oxygen in Chenle’s lung with ripe tangerines and burnt cinnamon.
He only stops eating him out when Donghyuck starts twitching with discomfort, moving to press his nose where Donghyuck’s balls meet his groin. This is embarrassing, a bit. He’s never needed this from anyone else, but as he takes a deep breath and lets all thought fly from his mind, Chenle’s never felt better.
Some minutes, or hours later, could be either, Donghyuck speaks up.
“You’re still hard.”
This, Chenle is aware of. Hard enough to hurt, hard enough to deliriously think he could come simply from having his face shoved against Donghyuck’s soiled skin. It won’t take much to pull that first needed orgasm in him, and so he figures, why waste it?
His body is always stronger during ruts, and so it’s easy to pick his body off from between Donghyuck’s legs to straddle his hips instead. He hardly bothers to properly pull himself out of his pants, knowing it won’t matter. He jerks himself quickly, just a few strokes —dry, painful, so fucking good— and that’s all it takes before Chenle is painting his tummy, his chest, up until his jaw with milky white.
He doesn’t even make a sound, chest stuck with his last inhale, too busy watching Donghyuck. His eyelashes flutter, and he’s so pliant with his hands by his head, palms up, vulnerable and his…
“Fuck, sorry,” he finds himself saying again, his hands moving to smear his come on Donghyuck’s skin before he can stop himself. It makes him gasp again, but thankfully he doesn’t look disgusted. Curious, maybe, as he watches through lidded eyes as Chenle keeps rubbing his come into his skin. On his stomach, where Donghyuck’s own spent had been, it mixes and mixes until all that’s left is the off-put shine, the tackiness of dry come. Chenle has the inexplicable need to taste it, and as soon as he thought it his body kicks into action, leaning down to press a few rushed, short kisses before his lips part and he can taste it. Gross, but it’s them, combined on Donghyuck’s soft tummy. Them, theirs, Chenle and Donghyuck.
“Sorry, that’s gross.”
This time when Donghyuck giggles, it’s for Chenle’s ears only. Fuck you, Sungchan.
“Yeah, it is a bit gross,” Donghyuck agrees, and Chenle can only hum as he continues to lick Donghyuck clean. Not everywhere, because he just… wants Donghyuck to be his, all ways possible, so that no one can have him like this ever again. “You’re still hard…”
His voice trails off quietly. He is still hard, the head of his cock looking an angry red, and his knot starting to swell at the base. That, too, is new. It usually takes Chenle longer to knot. It’s probably the fact that this is Donghyuck: not just anyone, not a friend willing to help him out. Donghyuck, his boyfriend, someone he loves in a way he’s never felt before.
Stringing words to form a sentence is a little too difficult right now, but he still tries his best. “Yeah. We should…” His sentence dies halfway as he starts running his hands down Donghyuck’s body again. His skin is all sticky, sweat, saliva, and come. He really does think he’s going crazy, but all he can think is Donghyuck. How pretty he looks, how he takes care of Chenle. How his body so easily gives to him; if he squeezes, his tan skin dents underneath his fingertips, turning white. He wants to leave a mark so bad he thinks he’ll die if he doesn’t, and it’s then that another unfamiliar feeling arises. His gums hurt. His mouth feels heavy, and as he runs his tongue over the top row of his teeth, he thinks he’s losing it when they feel sharper. The need to bite had never come up before. He’s never liked anyone enough for that, but right now, watching Donghyuck close his eyes and let Chenle do whatever he wants, the feeling is overpowering.
Words are too much of a chore right now, so he does what he does best and lets his actions speak.
Donghyuck is pretty light, but if it wasn’t for his rut Chenle doesn’t think he’d be able to pick him up and carry him like this otherwise. It’s a bit of struggle to pick them both up the floor —they were there long enough for Chenle’s knees to smart at the effort— Donghyuck yelps when he’s suddenly up in the air, but wrapping his limbs around Chenle’s torso makes the whole thing easier. He puts Donghyuck down on the bed more carelessly than he’d like to admit, rushing to finally throw his clothes off his body and be able to stick close to each other, chest to chest, skin to skin.
They stick together uncomfortably, all thanks to Chenle using Donghyuck as a cumrag, but he doesn’t care, can’t care as he slots himself in the v of Donghyuck’s parted legs.
“Wow, you don’t talk much in your rut,” Donghyuck murmurs as Chenle accommodates himself better, lifting Donghyuck’s knees so his legs wrap more comfortably around his hips. He’s getting hard again, Donghyuck, that is, Chenle has been hard for what feels like hours now.
It’s hard to listen to Donghyuck through the blood rushing in his ears, but Chenle strains his ears to hear him. “Yeah, ‘s hard to.”
He doesn’t really wait for an answer before dragging his fingers down Donghyuck’s body, again ignoring his erection and straight to his hole.
“O-oh!” Donghyuck yelps when Chenle pushes his index finger in, going on slowly until his knuckle meets skin. Even if his body was made for this, he’s always tight, and Chenle wants to make sure he’s comfortable. Donghyuck’s body is so expressive each time, and he gets lost in the warmth of his body once again.
It’s when he has three fingers stretching him out that Donghyuck gets impatient. “Come on,” he pants, his foot patting Chenle’s thigh. He’s red all over, even his knuckles are a pretty pink. Usually, Chenle would’ve left hickeys all over him, but he doesn’t trust himself with that right now.
“One more,” he says instead of sinking his teeth into his neck, instead of manhandling him so he can shove his cock down his throat. “Never taken my knot before.”
Even pheromone-addled, he expects Donghyuck to scoff, tease him a little bit. But all he does is agree, says okay, I trust you, in the sweetest whisper, Chenle almost stops the rhythm of his fingers. Suddenly hit by a feeling bigger than himself, he leans down to catch Donghyuck’s lips in a kiss. It’s messy, just like how it feels in Chenle’s head. Messy, wet, drool spilling from the corners of their lips only for Chenle to lap it up. As he’s kissing him breathless, he slips another finger inside Donghyuck, pulling out before pushing inside once again, slowly, slow so he can feel Donghyuck’s shudder run through him, eyes open even as they kiss so he can pay special attention to the way his eyebrows pinch with overwhelming pleasure.
This whole time he had been avoiding his prostrate on purpose; he wants Donghyuck to come on his cock and his cock only. But he brushes it right now, a touch that feels like mercy, and the groan that rips from Donghyuck’s chest almost sounds like it hurts.
Finally, he feels some of that usual insatiable energy coursing through him, not the mindless selfishness but a simple need of taking what is his, and he finds himself counting the seconds, watching as Donghyuck shivers and moans, counting how long it’ll take until he can finally fuck him.
It feels like an eternity when he finally feels like Donghyuck is loose enough. He’s pulling his fingers out and aligning himself before Donghyuck even realizes what’s happening, and then he feels Chenle’s tip run down his perineum, wetting the skin ever more with his precome, before finally pressing against his rim. He doesn’t think either of them breathe as Chenle pushes inside, inch by inch until there’s nowhere else to go.
Sex before Donghyuck was very casual. Fun, but impersonal. Now, even more than the other times they’ve been together, Chenle feels rubbed raw and vulnerable. He can’t look away from Donghyuck’s eyes as he finally bottoms out, brown eyes widening before scrunching shut, and only then does Chenle let himself blink. Hot, always burning hot inside, tight even after four fingers, Donghyuck’s body clenches around him like it’ll never let go, stuck together ‘till the end of time.
“I’m okay,” Donghyuck whispers after a few seconds of Chenle staying stock still. Chenle notices his hands are shaking, and he moves to drag his free hand down Donghyuck’s arm. He pauses with two fingers poised at his pulse point, feeling his heartbeat pound away, before moving to finally intertwine their fingers, pushing their palms together against the plush pillow.
“Fuck me, Alpha.”
That word, a simple, stupid word, makes him throb hard enough he’s sure Donghyuck felt it. The only other times where Donghyuck has called him that were in mocking tones, nothing but a chance to tease him and rile him up. But he said it lovingly, like he knows Chenle will give him all he has, and it spurs him on to pull out and shove back in.
It’s easy to build a rhythm of his hips with every staccato moan he punches out of Donghyuck. He’s so wet every thrust makes an obscene squelching sound, almost drowned out by the slapping skin hitting skin. He can’t help but glance down Donghyuck’s body, entranced by every single detail. His cock, way smaller than Chenle’s, a pretty pink even when soft, bobs with every thrust that shoves his body up the mattress. His skin is a mess, and he’s wet everywhere. Not just the sweat starting to drip down his body, but Chenle’s saliva drying tacky on his skin, the come he had smeared starting to crust on him. And then, the mess between their legs. Chenle can’t stop looking at it, at the way his cock keeps impaling Donghyuck’s body in an unforgiving rhythm. He’s wet, almost like how he would imagine he’d be like in his heat, rivulets of his slick drooling down Chenle’s shaft with each push of his hips, sticking to his pelvis and rolling down his thighs, hot, messy, glorious, Chenle wants to dirty him up even more.
Chenle only realizes he’s mumbling something when Donghyuck’s moans turn from incoherent noise to an actual word. Mine, Chenle repeats over and over again, and Donghyuck is always there, right next to him, yours, yours, yours.
Desperate, finally he recognized the familiar feeling, chasing his orgasm, chasing to plug Donghyuck up with his come, convincing himself it’ll take, even if he knows Donghyuck is on birth control, his Omega would be so good it’d take anyway.
“Gonna pup you up, baby,” he starts, in a voice he can hardly recognize as himself, deep and raspy. And it makes Donghyuck sob in response, a wet noise stuck in his throat even as he nods desperately. His knot feels heavy, popping in and out of Donghyuck every few thrusts, and he knows they won’t last much longer. “Fill you up with my come until it takes, let everyone know you’re mine.”
“Please,” Donghyuck begs, sounding as desperate and crazed as Chenle feels. “Chenle, please!”
He doesn’t even feel the strain in his thighs as he fucks him harder, deeper; he should’ve put Donghyuck in all fours, in a mating press, fucking him deeper, better, though he supposes that could come later. For now he just focuses on bringing him closer. Even naked, stuck together with spit and everything else, they’re not close enough, even as Chenle wraps his arms around Donghyuck’s waist to pull him flush against him they’re not close enough.
They talked about it briefly. Donghyuck had shrugged in a way he thought was casual, but Chenle knew it meant everything. You can bite me if you want, or not. Whatever you want.
But Chenle’s become an expert in reading Donghyuck, know that it actually meant I want you. Please want me too.
His knot finally pops in on the next thrust, and stays inside. He sees white for a second, ears ringing so loud he can’t even hear Donghyuck anymore, too overwhelmed, too needy. He only comes back to his senses when he feels himself moving again, sitting and pulling Donghyuck’s pliant body with him, until he’s on his lap like the most beautiful thing he’s ever seen.
“F-fuck, wait,” Donghyuck gasps at the sudden change in position. And Chenle listens, no better than a trained dog, stays still even though all he wants to do is grind into his inviting heat. “God, fuck, you’re big.”
It does great things to his ego, but he doesn’t have it in him to gloat about it. Instead he pushes the hair plastered to Donghyuck’s sweaty forehead away from his face, until he can see his dazed eyes again. They’re watery, gone, almost like he can barely see Chenle right in front of him?
“Hurts?”
Donghyuck shakes his head quickly, moving to wrap his arms around Chenle’s neck tightly. Close, not close enough. “No, it’s just a lot.”
Donghyuck sways his hips experimentally, causing them both to hiss with sensitivity, but he doesn’t stop, keeps grinding down on Chenle, using his cock to rub his prostate raw, his slick spilling down both their thighs. Everything is making Chenle feel like his head is full of cotton; wet earth, rain, Donghyuck’s tantalizing sweet smell, clouding his senses, the temperature in the room feeling like a furnace and making him dizzy.
His hands find Donghyuck’s hips easily. This angle is good, feels good, Donghyuck’s weight on his lap, the slow, sensual drag of his hips as he brings himself closer to an orgasm. He feels like he’ll explode if he doesn’t come right now. It won’t take long; he can feel it, can almost even taste it at the back of his throat, Donghyuck’s cock stuck between their stomachs, Donghyuck’s rim wrapped so tightly around his knot he feels wrung dry.
He doesn’t stop himself this time, when his gums start aching again. He lets his instincts guide him to the crook of Donghyuck’s neck where his scent is the strongest, kissing it deceptively soft before finally sinking his teeth in.
He knew they wouldn’t last.
As his mouth fills with saliva and blood, Donghyuck’s blood, he finally gets to do what his Alpha had been dying to. He comes, for so long he doesn’t even know how much time passes in that limbo. He only knows Donghyuck came too because of the wet sensation on his chest, but he knows it happens when Donghyuck’s whole body goes tight, tight, tight around him, arms and legs and ass squeezing around Chenle. And he gives, he gives all he has as he unlatches his mouth from Donghyuck’s shoulder to lick it clean. He gives him his body, his very soul, anything Donghyuck might want of him, he already has.
They don’t speak as they wait for Chenle’s knot to deflate. Halfway through he thinks Donghyuck fell asleep, his chest rising and falling slowly as they stay tangled together.
He has a perfect view of the bite mark, right at the juncture of his neck and shoulder. It’s strangely beautiful, for a wound that’s still red and swollen around the edges. Maybe next round Donghyuck can bite him too, a matching mark. This a new feeling during his rut, too: belonging. He feels calm, and not just because he had a mindblowing orgasm, but simply so content to know Donghyuck wants to be his. Not because of cycles or pheromones or whatever their biological needs are, but simply because they’re Donghyuck and Chenle, together.
When the knot deflates Chenle lays their bodies down carefully, still tangled, and falls asleep with Donghyuck in his arms.
His rut breaks three days later, after losing many things, such as their minds, their senses, and also, metric tons of body fluids.
Donghyuck has been whining for the past thirty minutes, and Chenle’s been a good sport about it. “God, I’m gonna need a week just ro recover from that.”
Their bed is clean, finally. Chenle doesn’t even want to think of the filth he made them lay on for days. Donghyuck had tried to change them, only for Chenle to growl and mutter like a dumb dog. He’d been bribed into showering a few times, food too, and that’s as much success as Donghyuck had gotten.
And copious amounts of orgasms, though Chenle’s smart enough to keep that to himself. Instead he fixes the heating pad that had started to slip down the side of Donghyuck’s lower back, making sure it’s centered before moving to massage his shoulders. He’s marked everywhere, bruised from Chenle’s lips, his fingertips, prints of his teeth littering his body, from the nape of his neck down even to behind his elbow, as if attacked by a rabid wolf. The smug pride that inflates his chest is a bit annoying, but Chenle’s helpless to it. Dumb alpha shit, as Donghyuck would call it, and he has to agree. Just some dumb alpha shit.
He’s careful of not touching the bite, which is looking pink and healthy rather than red and gnarly now. Pretty, will scar into the perfect mating bite.
“I’m sorry,” is what he ends up telling Donghyuck once he’s finished massaging him, in a tone more sincere than he expected. He goes to rest on his side next to Donghyuck’s body, carding his fingers through his soft waves. He’s surprised to find Donghyuck with a bashful look on his face, gazing up at him through his dark lashes. He hates that he’s all mushy now that they’re dating, but his heart melts at the pretty face he’s making instantly.
“Don’t be sorry,” Donghyuck’s lifts up a hand to wrap it around Chenle’s other wrist, squeezing softly before moving to tangle their fingers together. Everywhere their bodies meet is a pretty contrast, and Chenle can’t help but stare at how they look, they look like each other’s. “I’m just teasing…”
Chenle only hums back, lifting their tangled hands so he can press a kiss to Donghyuck’s knuckles.
“Still, I’m sorry, and thank you.”
Donghyuck can only stare at him for a few seconds with furrowed brows before he starts crawling closer, heating pad falling altogether with the thin sheet that had been covering his thighs. He wraps himself around Chenle’s torso like a clingy octopus, and Chenle welcomes him with open arms.
“Love you,” Donghyuck grumbles into his chest, like he’s annoyed by it. It makes Chenle grin, happy and shamless.
“Love you, too.”
