Summary:

“I wanna fuck you,” Yeonjun blurts out, his tongue moving faster than his brain. His fingers keep stretching Taehyun open, and it’s with a bit too much ease that he shoves his pinky into Taehyun’s hole as well. The lustful part of his brain tells Yeonjun it’s because Taehyun’s body opens up for him properly, expectant for a knot. Even though the rational part of his brain knows that that sort of biology is only ingrained into omegas. “I wanna—I wanna knot you.”

this is a rewrite from a fic i wrote for a different fandom!

Work Text:

Taehyun never calls Yeonjun like this. Partially because he likes to think that Yeonjun isn’t an alpha who only thinks with their knot, and mainly because they’re not mated.

But, of course they’re not mated. They’ve only been dating for seven months, coming up on their eighth month really soon, and have only known each other for the better part of one year.

Despite all of that though, Taehyun can’t help it. There’s a reason why the word—the title— is on the tip of his tongue whenever he stares up at Yeonjun. There’s a reason why a desperate, almost instinctual urge washes over his mind, his body, his senses—the urge, maybe even need, to address Yeonjun properly.

“Alpha,” Taehyun calls, and as the word spills from his lips, he can see it. As clear as day. He can see the look in Yeonjun’s eyes, he sees them flash blue for the smallest, shortest second in the world—but he sees it. And that’s all that matters. That’s all he needs to know.

Yeonjun isn’t an alpha who only thinks with his knot. They’ve only been dating for seven months. They’ve only known each other for a bit over a year. They’re not even mated. Taehyun is a beta—

But it just feels right. The words spill from his lips a bit too easily, like they were always meant to be spoken out loud. It’s a confession squeezed into one word which rolls off his tongue like syrup—thick, slow, and sweet.

“Alpha, are you gonna—” Yeonjun teases the skin of his neck between his teeth, and it shouldn’t feel like a bite, but it does. Yeonjun’s fangs, which Taehyun has felt against his skin a handful of times before, feel different this time. The way the sharp canines graze along his pulse point, following the vein of his jugular, before digging all the more teasingly into the surface of his skin… It feels like a claiming mark. The end of his question sounds nothing short of a whimper, “Are you gonna breed me?”

Which is impossible, they both know it. Taehyun isn’t meant to bear pups, his body can’t get pregnant, no matter how many loads of cum Yeonjun fucks into him. But that biological hindrance doesn’t prove to be a hindrance at all to them, because Yeonjun all but growls as he smashes their lips together. As if yes, he can breed Taehyun and give hum pups. Give him his children.

And it’s hot. Yeonjun is hot when he’s visibly trying not to let his instincts take over. Because there’s no good reason for why his instincts even make an appearance with Taehyun, much less why they should take over, at least technically. An alpha’s instincts are made to cloud their mind around their mated omegas, and knowing that Taehyun is neither mated to Yeonjun nor Yeonjun’s omega, but can still wreck enough havoc in Yeonjun’s mind to render him this close to snapping—

It’s really, really hot.

It’s clear Yeonjun thinks so too, because when Taehyun wraps a hand around his length from outside of his sweatpants, he’s already completely hard. The weight and heat of Yeonjun’s fully erect cock is familiar in his hand, so he doesn’t waste any time before kneading the heel of his palm against the other’s arousal.

“Will you?” Taehyun prompts, referring to his earlier question which had gone verbally unanswered. “Yeonjunnie hyung, are you gonna—”

“Don’t finish that question,” Yeonjun grunts, all but collapsing on top of Taehyun when the latter makes it a point to thumb under the head of his cock through the rough material of his sweatpants. Taehyun had been betting on Yeonjun going commando in these pants, like he always does. And he was not disappointed. “Or else I’m probably gonna bite you.”

“I’d like that,” Taehyun hums nonchalantly. At the same time, his hand easily makes its way past the waistband of Yeonjun’s sweats, gripping his hard and leaking length properly. “You know I would,” he adds, and then leans in to push Yeonjun onto his back, and kiss his neck. “Alpha knows me so well, hm?”

Yeonjun lets out a sound caught somewhere between a moan and something guttural instead of words, but Taehyun accepts it because he likes the sound of Yeonjun moaning just as much as the sound of Yeonjun speaking.

Yeonjun is propped up against the pile of pillows on their bed, legs spread open to accommodate the one thigh Taehyun shoves between them. His fist doesn’t let up around Yeonjun’s cock, and when the older spares one glance down just to see Taehyun’s tiny hand wrap around his girth, he has to shut his eyes immediately, another moan spilling from his lips.

“Good?” Taehyun asks knowingly, swiping his thumb over the head slowly, gathering precome which he then smears down along the prominent vein bulging out on the underside of his cock. “You’re really hard, hyung.”

“Of course I’m really hard,” Yeonjun snaps, but all the fire is lost as soon as it appears when he chokes on a whine, seeing as Taehyun tightens his fingers around the base of his length. “You keep—keep talking, like that, shit.”

Taehyun hums, but doesn’t say anything else for a while. He watches instead, as Yeonjun’s eyebrows scrunch together with pleasure, how his cheeks are painted a light shade of pink from the warmth running through his body, and how one of his hands unknowingly grab Taehyun’s wrist, the one connected to the hand still jerking him off.

Taehyun then lets his eyes fall to watch where Yeonjun’s knuckles turn almost white from how hard he’s gripping onto his wrist, but he doesn’t mind. Taehyun likes to watch the way Yeonjun’s tanner, just a bit larger, almost softer looking fingers wrap around his skin. How big Yeonjun’s hand looks no matter what part of his body he’s touching, because maybe withYeonjun, Taehyun is small.

“Your knot,” Taehyun says, eyes fixated on the swelling base of Yeonjun’s cock. His hand picks up its pace as he stares at it, and can feel himself become more aroused. He’s straining against his own pants as he listens to Yeonjun moan right next to him. “It’s big.”

It’s a stupid comment, really, because it’s not like this is the first time Taehyun has seen it. And it’s not like Yeonjun isn’t aware of the fact that his knot swells big either—of course he knows. He lives with it, after all.

“I know,” he blurts out before he can think twice about it. Though, it might have also something to do with how Taehyun manoeuvering his wrist just right completely obliterates Yeonjun’s ability to think at all.

“You know,” Taehyun repeats, but he’s taunting. Mocking. It’s clear in the tone of his voice, and the way he scoffs lightly at the end of his words. It’d make Yeonjun’s face flush red if he wasn’t already so blushed from the simple make out they were in the midst of before Taehyun opened his sinful mouth and shoved his hand down his pants. “You seem to know everything.”

“That’s not—” The sound which spills past Yeonjun’s lips is downright pitiful when Taehyun digs his thumb nail into the slit of his cock. “Not w-what I meant.”

Taehyun hums again. Yeonjun’s hips buck up into his first.

“Are you gonna come?” the younger asks, sounding like he was genuinely curious, and not like the answer was blatant and as clear as day in the way Yeonjun’s cock is throbbing in his hand. Still, Taehyun works deft fingers around the length, teasingly squeezing around the base, his knot, and the tip while waiting for an answer.

“Yes,” Yeonjun admits. He sounds ten times more breathless than Taehyun does, which would spark some type of competitive streak in him, at any other time. But right now, he’s going to come, right into Taehyun’s fist, onto Taehyun’s fingers. It always ends up like this when they try to fool around: Taehyun decides to bring out the worst in Yeonjun by spewing absolute filth into the air between them, and then lets him finish in his mouth, or in his hand. If Yeonjun is persuasive enough, he can even sometimes get away with fucking Taehyun’s thighs. “I’m gonna come, baby, fuck.”

Taehyun had noticed a long time ago that Yeonjun’s voice turns deeper when he’s on the edge of an orgasm. It’s because he’s so aroused, brain so clouded with pleasure, that his words slur together and fall heavy on his tongue.

It’s cute, when Taehyun gets to hear the low sound with Yeonjun fucking into him. During times like that, he can also feel Yeonjun’s rhythm turn sloppy, as well as feel Yeonjun’s cock twitch inside him, pressed tightly to his walls.

It’s cute like this too though. When he’s mouthing at Yeonjun’s neck, scraping his not as defined fangs against his boyfriend’s collarbones. He can feel Yeonjun’s thumping heartbeat against his tongue when he licks over the other’s pulse point, and it’s almost always in sync with the blood throbbing through Yeonjun’s cock too.

Taehyun loves it. He loves making Yeonjun come.

But he loves one thing a bit more than that.

Taehyun loves Yeonjun’s knot. 

Not that he’s ever felt it anywhere besides his hands, that is, or locked between his thighs. He’s laved his tongue over the swollen base before, and he’s peppered Yeonjun’s knot with kisses too.

The only place Taehyun hasn’t felt Yeonjun’s knot is the one place he wants it the most: stretching his hole open.

That’s what had brought on this whole scenario in the first place. 

“I want you to knot me.” And maybe it wasn’t the best idea for Taehyun to just blurt out his bedroom desires on a casual Saturday afternoon on the couch. But it’s not like he can take it back anyways, so he decides to just roll with it. “A lot.”

“Taehyun—” Taehyun knows what Yeonjun is going to say before he even says it. They’ve talked about this a handful of times, honestly. That’s also probably why Yeonjun knows what Taehyun is going to say before Taehyun says it, but the latter still beats him to speaking anyways.

“I want it,” he persists. He sounds adamant. Yeonjun knows he’s adamant. Otherwise they wouldn’t be having this conversation every two weeks. “We fuck all the time—I can take it. I can take you.”

Yeonjun fell in love with many of Taehyun’s qualities. One of the bigger ones being that Taehyun always, clearly knows what he wants. Another one being that Taehyun is determined to the tens—he stops at nothing. It’s one of the things they both have in common, actually.

“It’ll hurt,” Yeonjun states bluntly, because it will. It will hurt, Taehyun himself knows this. Taehyun himself has expressed the same words. “I don’t wanna hurt you.”

“When have you ever hurt me?” Taehyun rolls his eyes, and doesn't even give Yeonjun the time to answer. “Are you just never gonna knot me?” Taehyun crosses his arms over his chest as he asks, a challenging look on his face. “You’re going to have to eventually, when we get mated.”

Yeonjun pointedly ignores how Taehyun had said ‘when’ instead of ‘if’, and focuses on the conversation at hand. He could bring this up another time, in the future.

“I can’t just decide to knot you one day when we’re doing it,” Yeonjun explains calmly. “There’s a lot to think about because—”

“Because I’m not an omega? Because I’m not made to take it?”

“—because I don’t want to hurt you,” the older finishes, ignoring what Taehyun had interjected with. They both said basically the same thing anyways: it’ll hurt because Taehyun is a beta. His body isn’t meant to stretch around an alpha’s knot, but that doesn’t mean it can’t. It just means that the thought process before knotting him will just be a bit more tedious. “You know what I mean, right?”

“Not really.” Taehyun doesn’t even waste a second between Yeonjun’s question and his answer. “I’ve been stretching myself for it. I want it, hyung.”

“You’ve been what?” Yeonjun’s mouth parches, and his tongue suddenly feels dry. Did he hear that correctly?

“You haven’t noticed that my showers have been longer?” Taehyun shrugs, and then he lifts himself up, and unceremoniously plops down into Yeonjun’s lap. “Anyways, I want you to knot me.” He sounds like a broken record. “Your knot doesn’t go down unless you come, right?” Taehyun phrases it like a question, but they both know that he knows the answer.

“Yeah.” Nonetheless, Yeonjun indulges him. Taehyun nods once, and then smiles the same smile which Yeonjun fell in love with all those months ago.

“Good. You’re not coming today unless it’s when you’ve locked us together. Until I’m hanging off your knot.”

“Taehyun, you can’t mean that,” Yeonjun splutters, brain suddenly more alert. “Come on, baby, I can fuck you nice and slow, and we can spend the rest of—”

“Do I look like I don’t mean it, alpha?” Taehyun cuts off, raising an inquisitive eyebrow at the same time that his hand grips a bunch of Yeonjun’s hair.

Then Taehyun kisses him, and Yeonjun forgets just about everything.

So no. He didn’t think Taehyun actually meant it.

But here Yeonjun is though, being denied the urge to come by his boyfriend who abruptly takes his slick, warm, and tight palm off of his aching cock, using both of his hands to hold his hips down instead as he bucks into the air and cries out through the loss of his orgasm. He thinks the worst part is that Taehyun is just giggling as he ignores Yeonjun’s pitiful sounds, continuing to litter his neck with kisses and small nips.

“Hyung, I told you,” Taehyun mocks, after a minute or so has passed and Yeonjun doesn’t feel like the slightest thing will set him off anymore. “I want my alpha’s knot, and I want it now.”

My alpha.

Taehyun knows all of Yeonjun’s buttons, and while normally Yeonjun wouldn’t mind this, since he knew all of Taehyun’s buttons too, it’s times like this, when Taehyun has so clearly taken advantage of the upper hand, that he curses his boyfriend’s attentiveness.

“You,” Yeonjun starts around a breathless inhale, flushed face turning to glare at Taehyun. “You’re really asking for it, huh?”

“Begging for it,” Taehyun corrects, sitting up just a bit straighter. His hands have left their grip on Yeonjun’s hips, so the latter sits up straighter too. “I can drool for it too, if you’d like.”

Yeonjun knows he can—Taehyun is the messiest drooler he’s ever been with, when he wants to be.

“I’d like for you to keep your mouth shut,” Yeonjun grunts, having recollected enough of the mush his brain had melted into. One of his hands falls to Taehyun’s waist, while the other rearranges the pillows against the headboard so that Taehyun has somewhere comfortable to rest. “Be a good little beta and shut up for a second.”

Taehyun obeys just because it’s easy to listen to Yeonjun. And because it’s a bit hard to form any coherent thoughts with Yeonjun’s larger body hovering over him. 

Staring up at his boyfriend with shining eyes, Taehyun watches as he pulls his shirt off by grabbing the neckline. It was such a mundane action, but Taehyun can feel his arousal coil tighter in his tummy. Yeonjun doesn't take his sweatpants off just yet, but once he tosses his shirt off the bed, his hands immediately find the hem of Taehyun’s.

“Arms up,” he instructs, and while it’s the farthest thing from a command, Taehyun treats it like one as his arms obediently rise above his head. Yeonjun smiles as he pulls the shirt off of the younger, and then smooths down Taehyun’s ruffled hair when his head pops back into view. “See? Isn’t it easy to listen to alpha?”

Taehyun supposes that it is. So he nods his head, and watches tentatively as Yeonjun digs through the bedside drawer for lube. Once the bottle is settled next to his head on the pillows, Yeonjun is pulling the drawstrings holding his shorts up loose. 

He doesn’t pull them down, though. The drawstrings are pulled loose, and the shorts now sit loosely around his hips. But Yeonjun’s fingers pause where they hover above the waistband, and his eyes flick up to Taehyun’s face. A familiar smirk curls around his lips, and Taehyun feels his breath catch in his throat.

But first, Yeonjun kisses him. He leans up and presses their mouths together, wasting no time before licking into Taehyun’s mouth. His tongue swipes over his gums, tickles the roof of his mouth, and runs over the back of his teeth in a way which makes Taehyun shiver. When Yeonjun pulls away, Taehyun’s lips and part of his chin are covered in spit, while a thin string is connecting their lips together.

Yeonjun breaks it by running his tongue over his bottom lip, and then, he smiles. He smiles in the soft way which Taehyun usually sees on a regular basis, but seeing it now, when they’re both unfairly hard, stirs up something else in his chest.

Fire, probably.

“Taehyun-ah,” Yeonjun mutters. His hand comes up to cup Taehyun’s jaw, and his thumb scoops up the spit on his chin before pushing the digit against his bottom lip, the wet pad of his thumb meeting the slippery plush. “Open your mouth.”

Taehyun does, and Yeonjun’s thumb falls into his mouth easily. Taehyun licks off the now slightly cooled spit, and replaces it with even more, warmer saliva. But he doesn't get to continue for long, before Yeonjun pulls his thumb out of Taehyun’s mouth and instead shoves two fingers in.

He makes a small surprised sound in the back of his throat when Yeonjun’s pointer finger and middle finger press down onto his tongue, but he’s more than eager to hollow his cheeks around the digits and swirl his tongue around the length of them.

“Suck on them, baby,” Yeonjun encourages, gently pumping them in and out of Taehyun’s mouth too, just to see the way his lips wrap around them almost desperately every time he thinks Yeonjun is going to pull them out completely. “That’s it, good boy… Suck on them like you’d suck my cock.” As if that wasn’t what Taehyun was already doing.

While Taehyun is preoccupied tending to the fingers in his mouth, Yeonjun’s other hand finally pulls Taehyun’s shorts down and off his legs. He tosses the article of clothing off the bed, and nudges Taehyun’s legs open by the knees as he settles between them comfortably.

Taehyun had been smelling it since they started making out all that time ago, but as he watches a new, primal wave of arousal wash over his boyfriend, Yeonjun’s scent spikes, and Taehyun notices it all over again.

The smell of a thick, vibrant, healthy oasis. Hints of spring, hints of oak, and an overall refreshing woody scent which reminds Taehyun of what the air smells like right after rainfall. So strong that it’s all Taehyun can smell, so heavy in his senses that Taehyun thinks he can drown in it.

And that’s the thing: a beta’s sense of smell isn’t as strong as an omega’s or an alpha’s. Taehyun isn’t as sensitive to scents, nor does he pick up on them easily. But like everything else which should happen but doesn’t with Yeonjun, Taehyun is unnaturally sensitive to Yeonjun’s scent.

He can pick up on it from a mile away, and Yeonjun’s scent alone is enough to consume him whole. When Yeonjun’s aroused, Taehyun can smell it, and in turn becomes aroused too. When Yeonjun is upset, Taehyun can smell it, and knows what to do in order to make him feel better. When Yeonjun is overjoyed, Taehyun can smell it, and knows to enjoy whatever is making his boyfriend happy alongside him.

Yeonjun’s scent is almost syrupy in the air, so overwhelming that Taehyun thinks he can taste it on his tongue. His boyfriend, his Yeonjun, his—

“Alpha.” It’s a garbled call around Yeonjun’s spit soaked fingers, but it’s one which the older recognizes, nonetheless. Yeonjun looks up from where his eyes had been trained on the pucker of Taehyun’s hole clenching around nothing in anticipation and arousal.

“You really are stretched,” Yeonjun notes, and it almost sounds like he’s in awe. Like he didn’t take Taehyun seriously when he said he’d been stretching himself for it. For his knot. “You want me that bad, huh? Fuck, baby, you want your alpha’s knot that bad?”

Taehyun wants to roll his eyes—as if what Taehyun wanted wasn’t obvious, nor has been obvious for the past couple of months.

“I want you to knot me,” Taehyun whimpers around Yeonjun’s fingers, the latter finally taking pity on him and slowly pulling his fingers out. Though Taehyun does whine at the loss, even more so when Yeonjun wipes his sloppy fingers on Taehyun’s own cheek, yet he doesn’t pay it any mind. He has another task to focus on. “I want you to breed me , alpha.”

And then Yeonjun’s brain short circuits.

Because Taehyun repeats that same desire which he did not too long ago before denying Yeonjun his orgasm. 

Because he can’t. Not technically, at least. Because it’s not like Yeonjun hasn’t thought about it before, he’s an alpha, as it is. He’s thought about a lot of things when it comes to Taehyun, and it just makes him feel a bit better for it knowing that Taehyun has thought about it too.

“Breed you?” Yeonjun repeats in a mumble, now with both of his hands coming down to hold Taehyun by the thighs. Yeonjun’s hands aren’t too big, but they still wrap around each of Taehyun’s thighs nicely. 

Firm flesh spills from between the gaps of his fingers, and Yeonjun can’t help but bring his tongue out to lick over his bottom lip at the sight. His eyes then trail up to where Taehyun’s thighs meet his hips, and while he’s always thought this, this is the first time he can acknowledge it around Taehyun: Taehyun’s hips are gorgeous. They fit in his grip just right, not too wide but enough, and while Taehyun hadn’t been too flexible when they first met, he is now.

Yeonjun is suddenly reminded of all the times he’s watched these very hips work themselves up and down his cock. His throat dries up, and he brings his eyes back up to Taehyun’s face in order to regain some sense of composure, at least some lost shred of his sanity. 

“Yeah. I can do that,” he concludes, warmth swelling in his chest when he sees a small, satisfied smile bloom onto Taehyun’s lips. “You’re practically made for it, anyways.”

Which really… Is the farthest thing from the truth. Taehyun isn’t made to carry a litter: omegas are. But that doesn’t stop Taehyun’s body from being on the curvier side, for a beta. The small swell of his hips, the narrow shape of his waist. Taehyun’s chest which looks like it’d grow, given the chance, Taehyun’s pretty ass which Yeonjun can’t get enough of…

Sometimes, Yeonjun thinks that it’s not that Taehyun is made to be a beta. Sometimes, he thinks Taehyun is made for Yeonjun.

“Made for it,” Taehyun repeats, choking over his words because Yeonjun chooses that exact moment to pour cold lube directly onto his hole. 

“Oh, sorry, baby. Is it cold?” Yeonjun frowns, knowingly looking up at Taehyun with his sweet eyes, opened wide. The latter glares down at him, but Yeonjun pays it no mind before bringing three fingers to his hole. “Let me warm it up for you, then.”

Yeonjun starts by pressing the pads of all three fingers to his entrance. He begins by massaging his rim, and gets him to relax even more, further melting into the bedsheets. He feels the tips of Yeonjun’s fingers prodding into him, a teasing, barely there sensation presenting itself as a spoiler for what’s to come.

But he doesn’t stay focusing on that for too long, because his mind decides to go back to Yeonjun’s earlier comment.

“You’re practically made for it, anyways.”

Made for it. Taehyun wants to be made for Yeonjun. He thinks he already is anyways: from the way he’s extra perceptive and responsive to Yeonjun’s scent, from the way he shivers when Yeonjun’s teeth drag over his practically nonexistent scent gland, the way Yeonjun—

“You smell like a dream, fuck, Taehyun.”

—can smell him.

Because he’s not supposed to be able to. Only a beta’s claimed, marked, mate can smell them, and even then it’s a faint scent which they need to get accustomed to recognizing.

But it’s different with Yeonjun, because of course it is. Everything is different with Yeonjun, so it only makes sense that this is too.

Yeonjun has always been able to smell him, since the first time they’ve been intimate. He says that Taehyun smells like a tangerine plant: notes of not completely-there sweet citrus, the heady scent of nature, and an overall fresh and alluring scent.

No one in Taehyun’s life had ever been able to identify his scent, except for Yeonjun. And they’re not even mated—it honestly makes Taehyun dizzy when he remembers that fact. Yeonjun is not his mate, Yeonjun hasn’t even been someone he’s been dating for more than a year, but he knows. Taehyun wasn’t lying: his alpha really does know everything. And Yeonjun wasn’t lying either: maybe Taehyun really is made for it. Made for him.

“Really?” Taehyun asks, pulled back to the present and reminded of Yeonjun’s comment, when he feels Yeonjun push two fingers into him at the same time. He sucks in a sharp breath, and fists the bedsheets between his hands. “T-Thank you, alpha.”

Yeonjun hums, but doesn’t say anything else yet. He focuses instead on scissoring his fingers, once again taken aback by how easily Taehyun opens up around him. He really had been stretched previously. Two fingers easily turn into three, and when Yeonjun hears Taehyun moan loudly from above, he snaps his eyes up to his face.

Taehyun’s lower lip taken between his teeth, his eyelids heavy with pleasure, and his hair beginning to matte itself onto his forehead with perspiration.

“I wanna fuck you,” Yeonjun blurts out, his tongue moving faster than his brain. His fingers keep stretching Taehyun open, and it’s with a bit too much ease that he shoves his pinky into Taehyun’s hole as well. The lustful part of his brain tells Yeonjun it’s because Taehyun’s body opens up for him properly, expectant for a knot. Even though the rational part of his brain knows that that sort of biology is only ingrained into omegas. “I wanna—I wanna knot you.”

Yeonjun isn’t an alpha who thinks only with their knot. On a good day, at least. But now, four fingers deep into Taehyun and stupidly hard in the confinements of his sweatpants, Yeonjun’s knot is almost weeping for some attention.

Taehyun smiles lazily when he hears Yeonjun’s confession. Through hooded eyes, he meets Yeonjun’s eyes, which flash with a quick, passing blue every now and then. It’s a telltale for any alpha: Yeonjun is so aroused that it’s borderline pathetic. His alpha needs to fuck something, and with Taehyun right here, legs spread, hole glistening, and mouth parted around mewls of desperation, Yeonjun’s grip on Taehyun’s hip becomes almost bruising.

“Come knot me, alpha,” Taehyun invites, pushing himself up onto his elbows as he watches Yeonjun slowly, gently pull his fingers out of his now sopping hole. Yeonjun had used an absurd amount of lube. But he doesn’t mind, not really. He knows he’ll be needing it, after all. And, it makes him feel wet. Like he’s leaked an exorbitant amount of slick. “I've been waiting so long.”

Months, weeks, days… Taehyun has been waiting for so long.

Yeonjun makes a sound deep in his chest, and his scent somehow becomes even more intense. Waves of lavish forest, dew, and something that is so distinctly Yeonjun permeates through the air, and straight to Taehyun’s head.

“Sit up,” Yeonjun says, exhaling sharply through his nose when Taehyun obeys without wasting even a second. For the nth time, perhaps Taehyun really is made for him. “Good boy.”

Taehyun smiles without his teeth, and there’s something so distinctly familiar in his eyes as he stares at Yeonjun for a moment, that the latter almost forgets why he asked Taehyun to sit up in the first place.

“D’you wanna ride me?” Yeonjun asks once he remembers, though he’s already making himself comfortable against the pillows. Probably because he knows that no matter what, Taehyun is gonna nod his head eagerly with a,

“Yes,” he answers immediately, sitting himself quickly on Yeonjun’s lap. His thighs bracket the older’s hips, and his hands find home on his shoulders. “Gonna pull at your hair, by the way.”

Taehyun always warns him, though Yeonjun doesn’t know why he does. At this point, he knows it’s to come, and he’s always liked it when people pull his hair, anyways. But he likes it a lot more when it’s Taehyun who’s the one gripping his strands by the roots, and tugging until Yeonjun’s scalp aches.

Yeonjun rolls his eyes at Taehyun’s ‘warning’, and pushes his sweatpants down his legs finally. His cock slaps against his abdomen looking red, neglected, and angry, the tip shiny with beading precome. Taehyun stares for a few seconds, though Yeonjun thinks he’s actually only staring at where his knot is still swollen, and looking like it was in desperate need of some attention.

Taehyun lifts himself up with the help of his thighs, and Yeonjun takes it as his cue to line himself up accordingly. The head of his cock presses heavily against Taehyun’s entrance, and while Taehyun would usually take his time sinking down, if only to tease both himself and Yeonjun, he doesn’t seem to be wasting any time today. He slams himself down instantly, his ass meeting Yeonjun’s thighs with a loud smacking sound, leaving him to cry out at the stretch and Yeonjun’s immediate grip which flies to grab him by the hips.

“Fuck, Taehyunnie—” he hisses.

“Want it, I want it,” Taehyun reasons for his actions, breathing in rapidly, and heavily. His fingernails are digging crescents into Yeonjun’s shoulders, and from here, right in front of Yeonjun, his nose is so close to the other’s scent gland, that Taehyun ends up feeling a bit dizzy. “Alpha—”

“If you want it, you can take it. You just have to work for it,” Yeonjun says, just to hear Taehyun whimper in return.

But he does it. And he does it well.

Taehyun’s hips are practiced when it comes to riding Yeonjun, his lean, strong thighs helping him move up and down expertly, hips grinding in circles when Yeonjun hits the right spot inside him. Breathy moans fall from his lips with each movement, and throatier ones rip themselves out of his body when Yeonjun thrusts up in time with Taehyun slamming down.

In no time, Taehyun is stretched expertly around Yeonjun, the latter’s cock once again molding its shape into him, reaching so deep that if Taehyun sits down well and properly, a bulge makes itself apparent through the skin just a bit below his belly button.

“C-Can you—” Taehyun starts between cries of pleasure, dragging his nails down from Yeonjun’s shoulders to his biceps, deep, red lines following the movement. “Scent me please, alpha,” he whines, his thighs tightening around Yeonjun’s hips when the tip of the latter’s cock nestles right up against his prostate. He cries out as babbles begin to spill from his lips. “Please, please, alpha— my alpha—”

My alpha.

There is it again, and Yeonjun can feel the heady arousal start swimming in his head. His instincts are screaming at him to claim Taehyun, despite them not being supposed to. He just knows, he knows that Taehyun is his. Taehyun is meant to be his, that’s why his citrusy, fresh scent is always clogging his nose—

It’s why, as Yeonjun expels pheromones and further clouds the room in a thick layer of his scent, he feels the animalistic urge to bite. His nose is right at Taehyun’s scent gland, and while he knows that Taehyun’s scent isn’t particularly strong, or noticeable, for anyone except him, he feels dizzy and drunk off of the scent. Nosing right at it, Yeonjun smothers Taehyun in his own scent until Taehyun’s natural one becomes a bit more toned down.

Taehyun whimpers again, grinding more circles into Yeonjun’s lap, and this time the sound is right against Yeonjun’s ear. Taehyun’s lips press against the shell, breathy whines spilling right into it as Yeonjun starts to once again graze his teeth along the skin on his neck.

He can’t take it. Yeonjun knows that if he spends even another second in this torturous position, breathing in lungfuls of Taehyun’s scent and hearing his moans right in his ear, he’s going to do something stupid, like claim the beta right then and there.

Which is why he can’t contain the growl which rumbles out of his chest, nor the way he grabs Taehyun and easily overpowers him onto laying on his back, against the pillows once more.

“I need to fuck you,” he says, and Taehyun notes with ragged breathing and unimaginable arousal that it’s not a want anymore, but a need. “Fuck, Taehyun I need to breed you.”

“Yes,” Taehyun agrees, words light as he spreads his legs open before Yeonjun can say anything more. “Breed me, alpha. I can take it, ‘m yours, just yours, please—”

Yeonjun slides himself back into Taehyun in one smooth motion, cutting the younger off with his own sob. Taehyun practically squeals, but it’s a sound which dies down in volume and pitch once Yeonjun finds his rhythm and begins to fuck him in earnest.

One of Yeonjun’s hands make their way up to dig into the pillow right next to Taehyun’s head, while the other grabs Taehyun’s cheeks between his two fingers and his thumb.

“Look at me,” Yeonjun growls, and the sound of his voice alone draws a whimper out of Taehyun. “Are you mine, Taehyunnie? Are you my good little beta?”

Taehyun nods his head, but realizes it’s not enough for Yeonjun when he tightens his grip on his cheeks, Taehyun’s red lips pushing out into a fish’s pout at the action.

“Yours,” Taehyun nods, but it’s hard to do that, much less speak, with how Yeonjun’s hips are still pistoning in and out of him. “Mmh, Yeonjunnie— ‘M yours, alpha!” he moans, but this time it comes out more like a sob.

Yeonjun can tell from that, and from his faint scent, that Taehyun is close.

He releases Taehyun’s cheeks, but his hand doesn’t leave Taehyun’s face just yet. He starts by brushing Taehyun’s sweaty hair off his forehead, hips picking up their pace while simultaneously losing their rhythm: Yeonjun is close too. Once his hand smooths down Taehyun’s head, it falls down to the side of his face, resting just under his jaw. 

Yeonjun’s ragged breaths hitting Taehyun’s face, and the rise and fall of Taehyun’s heaving chest is spurring him on even further. Taehyun is close—and Yeonjun wants to see him come. He wants to feel it too.

“Taehyun-ah,” Yeonjun pants, staving off his orgasm as he feels it begin the bubble in his gut. Yeonjun’s hand then moves from under Taehyun’s jaw to grabbing his chin between his thumb and pointer finger. He brings his lips down, and lets them hover just a few centimetres above Taehyun’s own. “Come for me, baby.”

Taehyun cries, eyes squeezing shut, and lips parting around a stuttering moan which crawls out of his throat.

“C-Can’t,” Taehyun shakes his head, and Yeonjun is confused for all of one second (because Taehyun usually listens to orders so well), before the younger continues speaking. “Can’t come without your knot, alpha. K-Knot me, please?”

Yeonjun’s eyelids flutter shut, his eyes rolling into his skull behind them as he feels Taehyun clench around him impossibly tight, following his request. His hips still, and he moans gently when Taehyun wiggles his hips, very clearly trying to push himself down onto Yeonjun’s well and swollen knot.

“Baby,” Yeonjun breathes out, opening his eyes just to make eye contact with Taehyun’s own brown ones, shiny because they’re filled to the brim with salty tears. Yeonjun coos, and he brings his hand up to swipe the tears away when they fall with each and every blink of the younger’s eyes. “Are you sure?”

“I want your knot so bad, alpha,” Taehyun sobs, a sound which punches Yeonjun right in the chest. The want and the earnest desperation in his voice is as clear as day, even more so when Taehyun locks his legs around Yeonjun’s hips, keeping him close. “I-If you're gonna fuck me, I want you to fuck me like a real alpha.” Maybe Taehyun meant to sound threatening, or maybe even demeaning. Perhaps a bit condescending. But his words spill in the form of whimpers, and his crystalline tears don’t really solidify his statement.

Yeonjun’s alpha, nonetheless, is quick to take on the challenge.

“Deep breaths, Taehyunnie,” Yeonjun grunts, thrusting shallowly and teasing Taehyun’s rim with the heavy presence of his knot. A constant push for him to feel it, pushes which just have Taehyun’s breath quickening and quickening.

Yeonjun needs to see him come. Yeonjun needs to see his Taehyun come. His beta. And for that, if Yeonjun has to knot him first, then he will.

“C-Come for me,” Taehyun gasps out when he feels the beginning swell of Yeonjun’s knot breach his hole. He wills his mind to focus on the warmth and pleasure of Yeonjun inside of him, and the feeling of his hand rubbing his hip bone slowly, if only to distract him from the inevitable burn, stretch, and pain. “Yeonjunnie— alpha, come for me—” Yeonjun cuts Taehyun off with a kiss, the messiest one they’ve shared, and buries himself in completely, to the hilt.

Immediately, his knot locks them both together. The tightness surrounding his cock is nearly unreal, and having his knot buried inside his boyfriend, a beta, for the first time makes his head spin dizzily. Cum pumps out of him for what feels like hours, continuously filling Taehyun up. Yeonjun knows that when he eventually pulls out, a mess will follow.

The moment Yeonjun’s thighs slap against Taehyun’s ass as he slides in home, Taehyun cries out. Half in pain of being forcibly stretched around an alpha’s knot, and half in pleasure of feeling so unimaginably full. Yeonjun’s tip is lodged right against his prostate, cock buried so deep it shouldn’t even be possible. But it is, and Taehyun knows it is because the warmth of Yeonjun spilling, spilling, and continuously spilling cum into him proves it.

Taehyun can’t stop making sounds, whether they’re moans, cries, or blubbers which come out as sobs with every minuscule movement Yeonjun makes.

“Taehyun-ah,” Yeonjun pants heavily after he knows he’s done coming, wiping the steady stream of tears off of Taehyun’s cheeks. “How are you feeling? Are you okay?” One look casted between them shows that Yeonjun’s knot really had done it: Taehyun’s cum is painting his own belly and torso, cock laying wet and spent on his abdomen.

“Feel good,” Taehyun nods around a whimper, blinking teary eyes up at Yeonjun. Yes, it hurt, it hurt so much, but it felt so good too. Being filled up by his alpha, getting bred by him… Being locked together like this, breathing in each other’s post-sex scents… “Thank you, alpha.”

“No need to thank me, baby,” Yeonjun coos as he slowly tries to get them into a more comfortable position to rest in until his knot goes down. “You did amazing, my good little beta. You’re amazing.”

“Thank you,” Taehyun sniffs, curling into Yeonjun as much as he can given their position, and nosing as close to Yeonjun’s scent gland as he can. “Thank you. Love you.”

Yeonjun hums, smoothing a hand down Taehyun’s back and taking extra care to press firm and gentle hands to the bottom of his spine. If Taehyun isn’t sore right now, he’ll definitely be sore in a couple hours.

The aftermath of his body taking a knot when it, theoretically, isn’t supposed to. But, like a lot things about Yeonjun and Taehyun, what they just did goes beyond theoreticals and practicalities.

“Love you too, Taehyun.”
