Work Text:
Jisung has never been strapped to a breeding bench before.
He’s seen plenty, worked them a thousand times over, has had omegas tied down on them for his own ruts for years now.
But once the last strap is tightened around his waist, the growl builds in his chest and keeps going, louder and louder, until his beta colleague leaves the room and his scent fades away, smothered by Jisung’s alpha pheromones.
He fights it at first, as the drugs wear off. He knew he would; it’s why he’d asked to be drugged in the first place. He didn’t want to hurt his coworkers just because his instincts go haywire at the thought of being strapped down, being dominated and claimed, being bred.
The bite guard sits heavy in his mouth, the rubber forcing his jaw open just enough to make him drool on the tiled floor beneath him. It’s uncomfortable, but he prefers it over a muzzle, because the imprint of it bruises his face when he tries to bite.
Eventually, he settles. He shuts his eyes and just breathes, ignoring how exposed he feels by being naked in the sterile-feeling room. He still has his wits about him, his own rut still a couple months out, so he can reason with himself.
No one else would do this. Jisung is the only alpha employed here who was willing to accept an alpha’s request for his rut. It is certainly unconventional. Jisung has fucked countless omegas through their heats, has been tied down for some, but this is the first time an alpha has requested another alpha.
It almost hadn’t been allowed. Their director is a bit old-fashioned, not really welcoming the idea, but when Jisung had piped up and said he’d do it, there wasn’t really a reason to decline. Some of his coworkers had looked at him funny, but a bit of posturing and a curl of his lip had put them back in their place.
He’s not sure why he agreed so quickly. Especially now that he’s strapped down, his inner alpha is pissed at him, stirring stress in his chest, but at the time, he’d just thought about how he’d feel if he couldn’t have what he wanted - what he needed - for his rut. He’d go crazy.
Plus, his curiosity has always gotten the best of him. This may be his only chance to fuck an alpha uninhibited by anything.
There’s a grating buzzer sound, and then the steel of the door that separates him from the alpha’s nest is opening.
The stench of an alpha in rut hits him in the nose before the alpha even steps fully into the room. The growl is uncontrollable as it works its way back up his throat, growing as the alpha approaches.
Jisung thrashes against the bench hard when he feels a hand at the back of his neck. Without even thinking, he turns his head, trying to bite, but the guard keeps his fangs safely covered.
The alpha growls in return, loud and threatening as he bears his weight down on the back of Jisung’s neck, stifling the air out of him.
Jisung looks up to glare defiantly at the alpha. He’s lucid enough to tell how handsome he is, even if the lower half of his face is moderately obscured through the grate of his muzzle. There’s a crazed look in his eyes, glassy from the rut fueling his senses.
His fangs are sharp and dripping as he bares them at Jisung behind his muzzle.
Minho. This alpha’s name is Minho, Jisung remembers. It’s a good name. Suits him.
It takes a moment, the two of them locked in a staring contest, both snarling, before Jisung gets a hold of himself, dials back the urge to rip out of his restraints and fight. He’s the one with the presence of mind to think; this is his job.
Just be good, he tells himself. You’re good at this.
He snuffs out the growl in his chest, and pinches his eyes shut. It’s easier if he’s not looking when he turns his head, trying to bare his neck as best he can while strapped down. Submitting to another alpha, offering his neck to anyone but an omega he trusts - it’s new for him. But the shiver that courses through him is electric.
The next thing he feels is pain, the metal grate of Minho’s muzzle mashing up against his neck with too much force from how quickly he’d tried to bite him. Jisung is surprised to hear himself moan, feel himself chubbing up from being wanted so thoroughly, so fiercely.
When Minho accepts the fact that he won’t get his teeth into Jisung’s neck, he changes tactics, pressing closer until he can get his neck up against Jisung’s to scent him. Trying to keep calm, Jisung clamps his teeth down harder into his bite guard. It feels like he’s going to bite straight through it at this rate, but he knows it’s designed to hold his bite force.
Surprisingly, it gets easier to relax the more Jisung’s scent is overpowered by Minho’s rut pheromones. Minho’s wrists rub at Jisung’s tied down arms, fingers digging into him as he holds him in place even though the straps certainly won’t budge.
Soon enough, Jisung can hardly smell himself. He feels calmer, no longer worried about pushing out pheromones to posture in front of this alpha. Might as well just relax and take it. It’s his job, and he’s good at his job.
Once he’s seemingly satisfied with his handiwork, Minho straightens up, eyes flicking over the rest of Jisung’s body, layed out and prone. Head hunched between his shoulders, he prowls around Jisung in a circle. He’s stalking him, he realizes quickly, eyes trailing him as far as he can before Minho disappears behind him.
He’s shocked by how well Minho has held out until now. Maybe his rut is really just beginning, and he wasn’t waiting in his nest for Jisung to be ready. Jisung had expected him to be in the throes of it, desperate for a hole to fuck and fill.
Either way, his cock is hard and heavy between his legs, dripping at the tip, and Jisung suspects he doesn’t have much time before it bullies its way past his rim.
Hands slide up the backs of his thighs, fingers digging into the meat of his flesh, thumb brushing over his balls where they’re exposed under his taint. Jisung flinches, thighs tensing at the touch, an aborted snarl catching behind his throat. When Minho spreads his cheeks, there’s an annoyed sound - disappointed, maybe - the click of a tongue, a scoff.
“It’s broken,” he grumbles, the first words he’s spoken with a growl laced through them.
On instinct, Jisung is annoyed, tamping down his growl into a grunt at the last second. Broken? You requested an alpha, he wants to say, but it would do him no good and his words would slur from his bite guard regardless.
Minho pays him no mind, standing up fully. He grips Jisung’s hips, tilting them the way he likes with the minimal movement allotted to him. Jisung’s back aches from the arch in it, but he does his best to stay still, even as his cheeks are spread again to make room for the tip of an alpha’s cock to rub against his hole.
He’s tense; of course he is. He’s been fucked before, but not by an alpha in rut. Not with the fattest cock he’s ever seen in his life trying to fuck into his dry hole. He’d prepped a bit, but not as thoroughly as he probably should have, and not recently enough for there to be any residual wetness.
Minho doesn’t seem to notice - or care, at least - as he ruts between Jisung’s cheeks. The tip of his cock catches on Jisung’s rim a couple times, but it’s too dry and tight to do anything. Maybe that’s alright, though, Jisung thinks, as Minho growls behind him, precum leaking from the tip of his dick to slicken Jisung’s crack and drip down to his balls.
He must be pent up and desperate to get off, because Minho comes just like that, just from rubbing himself over Jisung’s hole. He’s loud with it, snarls and moans spilling from his lips along with the drool that slips past his muzzle to land on Jisung’s back where he hunches over him.
His lower back is coated in cum first, before Minho presses the tip up against Jisung’s rim to get as much of his cum in him as he can. Jisung growls, and suddenly Minho’s hand is on the back of his neck again, driving his weight into Jisung to pin him to the bench.
His other hand is moving, dragging through the puddle of his cum on Jisung’s ass to bring it lower, slathering it over his sac and then fitting his hand underneath Jisung, trying to get his cock covered as well.
Jisung moans, hips snapping to rut into the brief touch, even if he knows that Minho is doing it to cover his scent, to bury the muskiness of his cock underneath the strong tang of his own cum. Marking him.
Fingers find his hole, pressing cum into it in one smooth push. Jisung tries to relax, to allow the intrusion as best he can, and then the fingers are being replaced with the tip of Minho’s cock, still hard and dripping and eager for more despite having just climaxed.
The bench rattles, the legs of it slamming against the floor as Jisung jerks and snarls as he’s filled. He turns, teeth squeaking against the rubber in his mouth as he tries to bite at Minho’s hand again. He doesn’t even get close, and he’s forced to focus on the steady press of Minho’s cock as it carves a place for itself inside of him.
Drool spills over his teeth, past his lips and onto the ground in front of him in a string so viscous it stays connected to his lip until he thrashes his head again, trying to break out of his restraints.
Jisung hadn’t expected to take it so badly. He thought the mental prep and the scenting Minho had done would settle him, ease him into it, but the stretch is more than he expected, the girth of Minho splitting him wide open with no room to escape.
“Good,” Minho growls, a certain warmth in his tone as his hips press flush against Jisung’s ass after what feels like an eternity. That single word spills through Jisung’s bloodstream like a drug.
There’s no time to adjust, no time to think, as Minho pulls back and then drives his hips forward. Jisung’s skin is chafing where he tugs at his restraints - or, maybe it’s from the way Minho drags him back onto his cock, straining his body against the hold of the bench.
Jisung can only tell when Minho comes, because he can feel it drip out of his hole and slide over his taint as Minho keeps fuck him. His scent is strong, pheromones fierce from his orgasm clogging Jisung’s nostrils and making his head light.
It helps. It makes his hole looser and his heart calmer, so that by the time Minho comes again, Jisung is pushing back into his thrusts as much as possible, voice cracking on a moan, seeking out the pleasure of his cock rubbing against his prostate.
He doesn’t know how long it takes, how many times Minho comes before he’s finally ready to knot, but Jisung feels it growing against his rim after what feels like an hour of getting fucked. It’s thick, stiff as it bumps up against Jisung’s tight rim, still strangling Minho’s shaft.
It causes panic - the will to break free and fight until he can pin Minho down - to resurface, but it’s only for a moment - a quick, brief flash of something hot - before Minho’s knot forces its way past the resistance of Jisung’s tight hole. Then, Jisung’s whole body slumps against the bench in an instant as he tries to catch his breath.
Minho’s breath is ragged against his ear, and Jisung can hear his teeth click together as he tries to push past his muzzle to clamp down around Jisung’s throat. Jisung’s head lolls as Minho noses at him, bruising his neck with the pressure of the muzzle up against it.
Jisung has never felt so full in his entire life, and he can still feel Minho’s cum flooding into him - more and more, fuller and fuller. His eyes flutter shut and he turns his head to the side toward Minho to breathe in his scent.
The first time Jisung cries is the first time he comes. He knew, logically, that this would happen. That an alpha would be too single-minded in his rut to pay attention to Jisung’s cock, his knot, but experiencing it is entirely different.
Alphas always knot outside of a rut. It’s just a fact. Alphas in rut don’t knot every time they come, but it’s because they stay hard, producing more cum than usual to fill their mate as much as possible. Outside of a rut, there’s not as much necessity for it, so they just come, and then they knot.
Of course, there are instances that alphas can come without knotting outside of a rut, but it’s only when they’re being bitched. It’s a long process, which is reversible at every step, including being able to undo the entire process and go back to being an alpha. It’s fairly difficult, requiring a lot of dedication. But the first step is that an alpha won’t knot. There’s a transitional phase in the middle, and then, if everything is on track, they’ll start slicking.
Jisung wants to hold off on coming as long as possible, because he doesn’t want to knot without being able to touch himself.
The only time Jisung has ever gone without stimulating his knot was as a teenager, jerking off hastily in his room with no toys and wanting to see how it would feel if he didn’t crush his knot in the grip of his hands.
It had lasted all of about two seconds before he was scrambling to get a hold on himself. There’s no hope for him now as he spills his cum uselessly onto the bench, creating a river beneath them as it cascades over the sides.
Minho has been fucking him all day, only pulling out after each time his knot goes down and only long enough to scent Jisung some more. Or spread the puddles of his cum over him even more. He tries to avoid coming for as long as possible, because he knows it’ll hurt, but he can’t take it anymore. His prostate can only get bullied for so long before he needs to come.
He tries to press down, to get as much pressure on his knot by trapping it between himself and the bench, but Minho is tugging him back, the little give in the straps just enough for him to arch his back a little. Minho growls when Jisung comes, his hole squeezing tight around his cock as Jisung chokes on a sob.
The pain is a throbbing ache, pulsing from his knot through the sensitive tip of his cock and into his pelvis. He aches all the way to his bones, and even deeper, his instincts frantic with the need to plug someone up and fuck them full.
In a sick sort of way, the pain feels good. It’s something different, new stimulation after being fucked into for so long, and Jisung knows he’s going to grow addicted to the feeling. He won’t be able to stop coming now that he’s started.
Sure enough, the next time Minho knots him, Jisung comes just from the feeling of his rim stretching tight over his knot. This time, when he presses down, seeking out more pressure, Minho lets him, almost like he’s catching on.
He even trails his hand beneath where they’re connected, fingers pressing past his taint to get a hold of his balls, squeezing firm enough that Jisung thinks he’s trying to wring every drop of cum possible out of them.
The mix of the pain with the pleasure makes Jisung’s eyes cross until he pinches them shut, the growl in his chest half-hearted at this point. He does his best to squeeze his muscles around Minho’s knot even as fatigue tugs at the corners of his mind.
When Jisung wakes to the feeling of his used hole being prodded at, his first thought is I really am broken. He wants to be wet, be ready. It would be easier. It would make his alpha happy. He’d be able to take him sooner.
Yet Minho doesn’t seem to mind, dragging his fingers - wet with spit, lube, cum, something other than slick - over his hole before pressing them inside. He uses both hands, getting the first two fingers of each into Jisung far too fast. Jisung’s throat gurgles around whatever sound is trying to escape him as Minho pulls his fingers apart to test the gape of Jisung’s hole.
He must deem it satisfactory, because he’s fitting the tip of his cock inside in the next moment, punching a groan from Jisung’s stomach as he grows hard against his bench.
All his muscles tense, trying to fuck back against Minho as he digs his hands into the flesh of Jisung’s ass and starts pounding into him at an unrelenting pace.
It doesn’t take long for Minho to come; it never does the first time, and Jisung moans as he’s filled, tilting his hips in the way he’s found that Minho likes. But Minho pulls out anyway, leaving Jisung’s hole gaping and cold.
He rounds the bench, hand on his own cock, stroking furiously as he nudges the head against Jisung’s mouth. Eager to please, Jisung lolls his wet tongue out, dropping his jaw for Minho to press the spongy tip of his cock into the roof of his mouth.
When comes again, just a few minutes later, his cum streaks into Jisung’s mouth in sticky, wet ropes, and Jisung does his best to swallow without being able to shut his mouth fully.
Minho pulls his cock out and lays it across Jisung’s face then. His balls press against Jisung’s nose and mouth, and Jisung breathes him in. It’s a bit suffocating, to be trapped here, but Jisung finds he doesn’t mind much, as he does his best to lick at Minho’s sac while he strokes himself off over Jisung’s soft cheek.
His knot is starting to swell, Jisung can tell, and Minho wraps his own hand around it, choking it so it doesn’t hurt when he starts to come again, frighteningly soon after his last orgasm is finished.
He makes a mess of Jisung, coming all over his face, soaking his hair. Jisung pinches his eyes shut to protect them, and cum bubbles as he exhales out his nose and mouth, gasping for breath under the flood. Minho drags his free hand through Jisung’s hair with a slick, wet sound, and grabs at the side of his throat.
His fingers dig into his neck, making it hard to breathe for a moment as Minho works his cum into Jisung’s scent glands. Without his permission, a purr starts up in Jisung’s chest at the feeling of his scent glands being so thoroughly claimed.
Minho can only stand it for a few moments longer, though, his grip faltering around his knot. When he shoves back into Jisung’s wet, open hole, forcing his knot past his tired rim, Jisung comes again, howling as his own knot suffers as he makes a mess of his stomach, the bench, and the floor.
The palm on his lower back, pressing him down further feels like a mercy as it pins his cock between the bench and his own body. It’s the most stimulation his poor knot will get, so Jisung happily takes it, doing his best to clench around Minho’s knot in return.
On the third day, Jisung fades in and out of consciousness in the early morning. Minho had fallen into a fitful sleep at some point, leaned up against the side of his bench, head just barely brushing Jisung’s waist. It’s not customary - most alphas return to their nest in the next room in their moments of lucidity to rest.
He must have left at some point because Jisung feels hydrated, and he knows his beta colleague would not enter the room with Minho still in it, but he doesn’t remember his absence, or even the sound of the buzzer or the door opening and closing.
All Jisung can think about is how full he feels, even now, empty of Minho’s cock as he is. There’s so much cum in him, kept in by the very nature of the bench, angled just right to help it not drip out.
Minho is growling, still lost in his rut and not speaking much, but this time his face is buried between Jisung’s cheeks. The steel is cold against Jisung’s flushed skin for only a moment before it warms. His hole must be red and puffy from abuse, and it twitches against the touch of the muzzle as Minho tries to press closer, desperate to get his mouth on Jisung’s used hole.
He’s leaking, when Minho tugs at his rim and it twitches, pressing out cum. It makes Jisung feel a bit better, feeling like he’s wet for his alpha, ready for him to use when he wants. If only he could take his muzzle off and get his mouth on him, to really taste him.
Jisung moans, rolling his head to the side to drool onto the bench beneath his cheek as Minho stands up and fucks back into him. “Good omega,” he’s saying, and Jisung doesn’t even have the presence of mind anymore to question it. He is good; he’s being good, taking everything, getting so stuffed full for Minho.
“‘Mh guh,” he repeats, trying to speak through his guard. He feels dumb, drunk of Minho’s pheromones and the amount of cum he’s fucked into him in the past few days.
“Yeah,” Minho grunts, clearer than before. “You’re good. Gonna fuck you full, breed your little hole until it takes, huh?”
Jisung moans, eyes rolling in his head as his wrists twist in the restraints. He doesn’t want to be free so he can fight anymore. He wants to get out so he can touch Minho, run his hands over the planes of his chest as he rides him into the floor.
Minho comes, somehow finding more space inside of Jisung for his cum to fit. He stays buried deep, grinding into him to keep from fucking too much of his cum back out of him. Jisung can feel the way his stomach distends, pressing against the unforgiving leather of the bench as he’s filled again just a few short minutes later.
It’s four this time - four times Minho comes in him before his knot takes, and Jisung is so fucking full now, he doesn’t know how he’s going to take Minho’s knot and all the cum that comes with it - there’ll be nowhere for it to go.
When Minho knots him, the sound that comes out of Jisung’s mouth is completely inhuman. The sloshing feeling of cum inside him travels upward through his abdomen, pushing and pushing until his stomach aches with the feeling of being so full. There’s no give, no room for his belly to swell much more than it already has, not with the way he’s tied down.
Jisung groans, his stomach turning in discomfort as bile rises up his throat, pouring out of his mouth in a steady stream with his drool as he salivates enough to lubricate his throat. He coughs once, and then he’s gagging on the feeling, retching until a mouthful of liquid spills out of him.
He looks down, watching as white drips from his lips and onto the ground below him. Once he starts, he feels like he can’t stop, and he gags again, cum falling right out of his mouth and onto the floor.
It reeks more than it usually does, having worked its way backwards up Jisung’s digestive tract. He pukes again, a seemingly endless flood, whining as he bites down harder on his bite guard, trying to clamp his mouth shut and keep it in.
He’s wasting his alpha’s cum on the floor.
It takes Minho a minute to realize, his rut brain leaving him with the sole focus of breeding Jisung’s wet, sloppy hole. But once he does notice, he’s growling in displeasure, reaching to fist Jisung’s hair and pull his head up.
He chokes, cum and spit dribbling down his chin as Minho grinds his knot into him. His hole tightens, trying to milk the last remnants of his cum out of his knot before he’s able to pull out.
“Al’ha,” Jisung slurs through the rubber, eyes rolling in his head as its shaken by Minho’s firm hand.
“Keep it in,” Minho growls, pulling back to fuck his knot in and out of Jisung’s puffy rim a few more times, making it loose enough that it’ll surely gape when Minho leaves him empty.
“Ahm ch- chrying,” Jisung whines, pinching his eyes shut as another wave of nausea causes him to retch. He coughs it out this time, and it lands in a wet splat, plopping into the puddle beneath his bench.
“Useless,” Minho spits, tearing his knot from Jisung’s hole and making him wail. Minho marches around the bench, his footsteps wet from Jisung’s cum. Jisung tightens every muscle in his body, trying desperately to keep the cum inside his loose hole.
It doesn’t work; he can feel it coming out of him quickly and he chokes on a sob as he panics. Minho growls at him, baring his teeth behind his muzzle. His fingers are grabbing at Jisung’s jaw, prying it open enough to rip the bite guard out of his mouth.
He’s probably not supposed to do that, Jisung thinks vaguely, but he knows it’ll be okay. He’s not going to bite his alpha. He’s going to take care of him.
Minho’s hand is reaching for the buckle on Jisung’s forearm next, deftly ripping it out of place so his hand is free. “Keep. It. In,” he repeats, eyes dark and threatening as Jisung hurries to comply.
His jaw is tugged open wider at the same time he fits his fingers into his hole. Two doesn’t help, the cum still pouring out around them like a faucet as Minho slides his cock into his mouth, pressing, pressing, pressing, until he’s in his throat. Jisung gags wetly around his cockhead, his stomach lurching has more cum heaves up from his stomach out of his mouth. Minho holds him down so it has nowhere to go but back down, only a little spilling out the sides of his mouth.
Jisung tries to focus on himself, getting a third and then a fourth finger into his stretched hole to stop the cum from spilling out. It leaks at the edges, but at least it’s slowed as Jisung’s nose is mashed against Minho’s pelvis, making it hard from him to breathe.
His eyes roll in his head, and in a last ditch effort, he pulls his fingers out with a slick sound, and then fucks his whole fist back in, desperate to plug himself up and stop dripping cum all over the floor.
His cock throbs between his legs, and he’s happy he hasn’t come again yet, not ready for the pain of his knot.
Minho’s hand is so tight in his filthy hair, and the other cradles the back of his head before sliding down to the back of his neck. The angle strains his neck as Minho snaps his hips, fucking into Jisung’s throat, but it hardly matters. Jisung can’t focus on anything that’s not Minho and the tip of his cock punching the back of his throat.
Jisung can feel it when Minho’s knot starts to swell again, if only because it bumps against Jisung’s lips, mashing them against his teeth, surely turning them purple and blue with bruising later.
He’d been waiting, usually not pressing his knot inside of Jisung until it was at its largest, but now he presses it past Jisung’s teeth early, thankfully easing the way to fit it into his mouth. Jisung tries to moan in pleasure, or maybe discomfort, but it bubbles with cum at the back of his throat and he chokes on it.
Minho’s knot hooks behind his teeth, and he’s sure his fangs are digging into it uncomfortably, but Jisung can’t focus on anything but the swollen knot in his mouth, still filling out, pressing his tongue down until he chokes and gags, stuffing his face so full that he hears a loud, sickening pop in his jaw.
He has no time to think about it, because cum is pouring straight from Minho’s cock into his stomach. There’s no room for it anywhere. The cum in his ass is slick around his own wrist as he shifts his hand, knuckles brushing dangerously against his poor prostate. The sound of it being forced out past his wrist is objectively disgusting, and Jisung whines when he hears it.
Tears are wet down Jisung’s face, joining the mess of drool and cum that already reside there. He retches again, cum and snot dripping from his nose. He’s so thoroughly fucked he can’t breathe, can’t move, can’t even think.
When he blinks up at Minho, there’s the ghost of a smile on his lips, twisted in a mischievous way behind his muzzle.
It makes Jisung come instantly, trying not to bite down as his eyes roll back in his head. He must black out for just a second, but he tries to stay conscious, to breathe, so he can ride out his orgasm by pressing back against his fist, having no strength to fuck himself with it.
When he comes down from his high, Minho’s knot is gone, but he makes no move to pull his soft cock from Jisung’s busted, bruised lips. His hand is gentle for the first time as he strokes Jisung’s wet hair away from his face, and Jisung lets himself lean into the soft touch as he closes his eyes.
Minho smells so pleased, so satisfied, that Jisung can’t help but preen, smiling as much as he can around the cock in his mouth. He’d done so well taking care of his alpha.
It’s only after the fact, once he’s caught his breath, that Jisung realizes, in the midst of his pleasure, he hadn’t popped a knot.
