Chapter Text
The halls were dim as his clacking footsteps fell one by one across the concrete floors, the fluorescents flickering overhead in a faint buzz that often made his skin itch. The doors creaked on metal hinges, an array of sounds echoing through the viewing slats in each—low, rumbling growls and pitched, wailing moans and the rapid smacking of flesh on flesh.
A breeding facility—the most highly ranked in the nation—specializing in hard to domesticate cases. The alphas that arrived most often came from illegal fighting rings that had been broken by the authorities, leaving the hybrids that had been trained solely to fight for their dinners without a home that could keep them. So they came here, to be retrained, made docile and fit to breed the omegas the facility kept.
The omegas were nothing special, often strays picked up off the streets, some dropped off by owners that couldn’t keep them any longer. Most of them were kind, soft, and scared. Most of them deserved better.
It was why he worked so hard, why he refused to ever allow an alpha through without properly breaking it in. He wouldn’t allow the sweet omegas to be hurt because of his negligence.
His heeled boots made a final clack as he reached the end of the hall where two, tall beta males stood waiting in front of the metal door.
“You’ve got your work cut out for you with this one,” the blonde grumbled, as the brunette handed him the clipboard stacked with documents. “Crazy motherfucker about bit my arm off.”
In proof, the man lifted his sleeve to show the rapidly healing bite on his forearm.
“It’s your own fault,” the brunette scoffed. “I told you to stop teasing him.”
“I was just trying to lighten the mood,” the blonde argued back.
He hardly paid attention to them, flipping through the papers to evaluate his newest case.
“He’s in rut?” He observed, with a pointed sniff to the air as he read over the third document establishing the current condition of his health
A fine alpha—he would breed well, once he was broken in, of course.
“Second day,” the brunette confirmed. “I told them it would be better to wait, but they’re antsy to get him breeding. He was a top fighter. And they claimed his rut would last too long. They want him to breed Hajoon before his heat is up.”
“How long are his ruts?”
“His last one was a full week,” the blonde answered.
His brows went high, before he shook his head in disgust. “Hormone injections, I’m guessing. Damn fighting rings.”
“If he’s not broken in by tomorrow,” the brunette said with a grave expression, “they’re going to go through with the breeding anyway.”
He cursed internally, restraining the urge to throttle some old, money hungry humans.
“He’ll be broken in,” he promised confidently, letting the papers flap back. “Have I ever failed before?”
“Never,” the brunette gave him a smirk. “But keep that in mind once you get in there.”
He simply rolled his eyes at the beta’s doubt, and waited for him to pull the door open before stepping inside.
The room was small, and even dimmer than the halls. With the chains hanging from the metal rafters and the lack of windows to provide any comforting light, it closely resembled someone’s basement turned torture room. But it wasn’t meant for torture, not really.
Restrained by a pair of chains hanging in the center of the room knelt the alpha, head hung and body slumped against the pull on his arms above his head. His ankles were chained to the floor beneath him, and his dirty clothes hung in practical tatters off his solid frame.
He took a moment to observe the alpha—broad shoulders, onyx hair soaked in sweat and clinging to temples, thick arms, narrow waist, strong thighs, and from what he could see of it, a pretty, sharp face. It was no wonder they were antsy to breed him. He would make fine pups indeed.
And he was clearly antsy to breed as well, if the heavy, almost suffocating scent of his pheromones teeming through the room was any signifier. The alpha was deep in rut, and it became all the more clear when a low, menacing growl reached his ears.
“Choi San, correct?” The omega began, flipping through the paper once again as he walked over to lean against the metal table a few feet in front of the chained alpha. “Age twenty-seven, fighting alpha. Oh, you’ve bred before?”
The growling didn’t cease, if anything, it grew louder as he spoke.
“It seems your previous owners didn’t care much for privacy, hmm?” He observed, reading the lines of how the alpha had been restrained as he was brought omegas to breed, all under the eyes and whips of his owners. Deplorable. “We’re far more civil here. Provided you behave and cause no harm, this should be the only time you are restrained during your stay here. Doesn't that sound nice?”
The growl only grew more menacing.
“Which is where I come in,” he continued, setting the clipboard down and unfurling the rollout fabric containing his instruments on the table. “My name is Wooyoung, and I’m going to train you, San.”
A snarl sliced through the air. If Wooyoung were anyone else, it might have set his hair upright across his skin, but now, it never phased him anymore. He was used to vicious alphas, and he was used to breaking them until they were whimpering and docile.
“You don’t have to be scared,” he hummed calmly, fiddling with the straps in the fabric as he pulled his instruments free. “This can be as easy as you make it, San. If you work with me, it can actually be fairly enjoyable for you.”
Not likely.
He pulled two vials free first, and turned back to the snarling alpha, only to be pinned in place for several seconds by the crimson eyes staring at him.
Choi San had a sinister look—slanted eyes and strongly cut features beneath dark hair to frame them like a silent threat. The omega could see how even his predatory gaze would drive fear into the hearts of his opponents, and the way his lips drew back to show gleaming fangs as he snarled again nearly did the same to Wooyoung.
But he wasn’t afraid. He was calm, confident. This was his job, and he always succeeded.
His heels clacked against the floor as he took the few steps to stand no more than a couple of feet in front of the alpha, and held up the two vials in his hands.
“See these?” He asked, but San didn’t look away from his face for a second. “I’m sure you’re very familiar with both.”
Something in the alpha’s gaze set a slight prickle of nerves in his stomach. The intensity was intimidating enough without the practical foam building around his teeth from his current display, but there was something else. It was as if he were looking right through him, past the wall he put up, straight into his conscious.
“This one,” he held up the vial of lavender tinted liquid first, “is wolfsbane.”
The uptick in his snarling was immediate, his eyes glaring harder as he jerked against his chains for the first time.
“Ah ah,” Wooyoung tisked, shaking his head. “Remember what I said? This will be as easy as you make it, San. If you don’t disobey, or growl, or struggle, then I won’t have to use this. Think of it as a punishment, hmm?”
San truthfully still didn’t show any signs of understanding him, and Wooyoung began to wonder if he was even lucid enough to comprehend his words.
“And this,” he continued, holding up the vial of milky fluid this time, “is omegan slick. A reward—all you have to do is listen to what I say, and calm down. That’s not so hard, is it?”
Another snarling growl, and Wooyoung knew he was in for a long session.
He sighed, turning away and walking back to the table. He heard a harsh jerk and rattling of chains behind him, followed by the fiercest growl so far.
“So it’s going to be like that, huh?” He shook his head, picking up the riding crop from the table and popping the top on the vial of wolfsbane. “You know, I really take no pleasure in your pain, San. I just want the best for you. You’ll have a happy life here, much better than your last.”
He took his time coating the absorbent riding crop in the lavender fluid, nose scrunching at the stench. It was never pleasant for him, but he knew it was a thousand times worse for an alpha.
The growling was nonstop now, and when Wooyoung turned back, he froze in a pause.
The alpha was fully humping the air now, drooling down his chin with his eyes glued to the omega’s frame. Despite the wolfsbane now drifting in the air, he looked more feral than ever.
“Interesting,” he hummed. “I guess you’ve gotten pretty used to that smell. No matter, it will burn just the same.”
To prove it, he laid a light strike of the crop to the alpha’s arm, just below his bicep. The reaction was instant—a jerk against the chains, a yowling growl, and foaming saliva dripping from gnashing fangs.
“See? It’s no fun is it?” He sighed, twirling the crop in his hand. “Wouldn’t you rather avoid that? Wouldn’t you rather feel good, San?”
He waited for one of two reactions—for the alpha to try to bite him or attack him or escape once again, or for him to whine, whimper, soften.
Neither happened.
Instead he watched as drool continued to drip down his chin, his red eyes piercing, and his hips beginning their rut against the air once more as he continued snarling.
“Very interesting,” he hummed again, before pulling the vial of slick back out from his pocket and popping the cap. “Perhaps you need to see what you’re working towards first. Wouldn’t you like to breed, San? We have omegas lined up waiting for you. All you have to do is relax.”
He extended his arm, passing the vial in front of the alpha’s nose to waft the scent. And again, he waited for one of two reactions—a spike of rut that would him jerking to release from his restraints, or one that would have him grinding against nothing even more, desperate to bury himself in the omega that wasn’t even there, who’s slick coated his nostrils.
And again, neither came.
Instead, Wooyoung’s eyes went wide as he jerked away from the vial, snarling and spitting as he tried to get as far from it as possible.
Well…that was new.
Wooyoung stared in confusion, even sniffing the vial himself to make sure it hadn’t soured. But it was perfectly sweet, laced with vanilla and toffee butter. So why would a rut crazed alpha not want to smell it?
His confusion only grew as the alpha stared hard at him again, body strained against the chains as he tried again to get closer to the omega, nostrils flaring and pupils wholly dilated.
Was he that aggressive? Was he only concerned with harming his captor? No, that couldn’t be possible. Any alpha in rut would be far more concerned with breeding any whiff of omega—
Wooyoung froze, eyes stuck hard on the way the alpha’s nostrils flared over and over as drool ran fast down his chin.
It wasn’t possible…and yet…
He extended the vial once again, and once again, San jerked away, snarling and spitting. Then, he capped and pocketed it, before extending his wrist back out.
It was immediate. San was jerking against the chains without hesitation, desperately trying to get closer to his wrist, nostrils breathing in so rapidly that the omega was worried he might faint from over-oxygenating his lungs.
San could smell him.
“How–“ Wooyoung breathed, a sudden twisting of apprehension in his stomach.
No alpha had ever been able to smell him during sessions, not when Wooyoung wore enough scent blockers for three omegas, or when he stayed plugged with an absorber so that even rut pheromones wouldn’t cause the scent of his slick to fill the air. There was no way that San should be able to smell him, and yet…
This was a problem.
He walked quickly back to the clipboard, ignoring the sounds of the alpha desperately trying to follow, and began flipping through the pages rapidly.
Nothing. Not a single note or line or stamp to signify that this alpha had an unnaturally high sense of smell. Which meant they didn’t know.
And it meant Wooyoung was now faced with a choice.
He couldn’t use bottled slick as a reward if the alpha was disgusted by it, now that he had latched onto Wooyoung’s scent. Which meant he was without incentive. San would have no interest in the promise of breeding the pretty smelling omegas waiting for him until his rut had passed.
Either he would have to admit defeat, allow his perfect reputation to be ruined, and risk Hajoon’s safety to be bred by a feral alpha, or he would have to find another method, another reward.
And Wooyoung was never one to back down from a challenge.
If San was feral before, the state of him as Wooyoung removed his scent blockers was purely rabid. For a moment, he actually feared that the chains might not hold him.
But they did, even as Wooyoung came closer, leather crop in hand.
“Now Sannie,” he hummed, spinning the stick. “I want you to listen to me very carefully. Ah ah, none of that. Don’t you want to be rewarded?”
His snarling still didn’t cease, and a smack of the soaked, stinging leather to his ribs only made it grow in ferocity.
“All you have to do is calm down,” he continued, watching the alpha as he only began rutting against the air again. “No growling, no biting, and just a few little words. Can’t you do that for me, Sannie? Just those few things, and I’ll give you a treat, hmm?”
But San didn’t seem to care, too focused on staring him down and sniffing over and over as he thrust against nothing, his growling so furious and desperate that it was beginning to make Wooyoung a little dizzy.
Another smack to the alpha’s skin, and he was gnashing his teeth at Wooyoung.
And coming in his pants.
Wooyoung could smell it even before he heard the alpha’s growl take on a more guttural edge, his eyes fluttering just a little where they fixed on the omega’s face, his tongue out as he panted, drool dripping to the floor.
“Mmm there you go, alpha,” Wooyoung smiled softly, reaching up carefully to rub between his ears. “Feels better? Don’t you wanna cum some more? Omega can help you feel all better. All you have to do is calm down, Sannie.”
But the moment was short lived. It only took seconds for San’s growling whines to kick back up even louder, as his head jerked to try to bite at the omega’s wrist.
“Ah ah,” he sighed, delivering another firm smack of wolfsbane soaked leather. “No biting, Sannie.”
But through the passing minutes, Wooyoung realized how pointless it was. Nothing was making a difference, no matter how many stinging welts he left. He didn’t have a real incentive for the alpha, and San was clearly far too hopped up on hormones to comprehend what he said.
He needed to knot.
And after several more minutes of contemplation, the trainer made his decision. He refused to be defeated. He refused to let San beat him.
The growling groan that San let out was a near whine as Wooyoung palmed him through his tattered pants, sinking slowly to his knees and ankles as he held the alpha’s eyes.
“It’s okay, alpha,” he promised, smiling softly as the hybrid began bucking forward, trying to seek out more friction. “Omega is gonna take care of you. You’ll feel better once you knot, won’t you?”
The begging whine in his growl was enough for Wooyoung, and he slowly slipped his pants down and peeled his sticky boxers away until the length of him sprang free. San was large, even for an alpha, and Wooyoung wondered for a brief glimpse what it would feel like.
But that was his omega talking, driven by the stench of rut pheromones in the air. The important thing now was getting San to calm down enough to be trained.
“Shhhh I know,” he soothed as the alpha let out a desperate, whining snarl the moment Wooyoung took him in hand, hips nonstop in their bucking so that the omega didn’t even have to move his fist, simply squeezing tight and giving San a hole to fuck into. His fingers didn’t even wrap all the way around, but the alpha didn’t seem to care. “That’s it, alpha. Just like that. Come on, show omega how you knot.”
It was only seconds before the alpha was whining again, spurting ribbon after ribbon as Wooyoung jerked him through it, ignoring the stray drops that landed on his cheek before he could move out of the way.
But still no knot.
“Can you give me another, alpha?” He asked, squeezing just below his cockhead as the hybrid whimpered, slowly taking up a growl once more before resuming his rutting, his slickened dick sliding in and out of the tight grip with ease. “Mmm yeah just like that, alpha. Omega wants to see how big and pretty alpha’s knot is. Please?”
San was shuddering against the chains in seconds, sounding like a kicked puppy, whining and whimpering as he sprayed another load to no avail. And once again, all it succeeded in doing was seeming to drive his insanity higher.
This still wasn’t working, even as Wooyoung did all he could to massage the base of him with his other hand. There were still no signs of a knot swelling.
Perhaps he needed something a little more warm and wet, something that better resembled what he really wanted.
So with only a few more seconds of hesitation, Wooyoung took him in his lips, nearly choking as the alpha immediately thrusted forward into the cavern. He was certain his teeth grazed him, certain that it couldn’t have even felt that great because he couldn’t even suck around him as he began bucking into his mouth, but San’s feral sounds and fiercely hungry expression said otherwise.
It took everything in him not to pull away to catch his breath, gag after gag convulsing his throat as the alpha pounded in without care, greedy for a hole to fuck. And maybe it should have been more uncomfortable. Maybe it should have only felt like the chore it usually was to calm a rut crazed alpha. But then again, Wooyoung couldn’t even remember the last time he had an alpha’s cock down his throat, and San…
Gods above he tasted so good. When he slammed hard into the omega’s mouth for the final time, cockhead deep in his convulsing throat as his curved nose buried in the patch of sticky hairs on his pelvis, Wooyoung felt himself clench around the plug inside of him.
San was musky and heady, the taste and smell thick and earthy, something like the forest first thing in the morning as it sparkled with dew, like wet cedar and damp moss. It was intoxicating, like chugging a bottle of alcohol in far too little time. Each pulsing ribbon slid down his throat until he was choking on it, pulling away panting as San continued to spurt all over his face.
“Fuck,” he breathed, almost laughing. “How do you even have so much in there, alpha? You must really wanna breed me, huh?”
The yowling growl was answer enough.
And maybe it was the lack of oxygen, or the fact that the pheromones in the air were enough to send any omega to their knees, spreading their cheeks to present. Or maybe he just felt San had earned a reward for sticking through it this long and coming so many times. Or possibly, he thought that perhaps it may help the cause, that perhaps its absence was making it harder for the alpha to knot.
Whatever the reason, Wooyoung found himself reaching his hand down, dipping his fingers past his waistband until they were grasping the little metal base of the plug nestled between his cheeks. Then he pulled it free.
And once again, he feared for the durability of the chains keeping the alpha in place as Wooyoung raised the absorbing plug up, looking over it.
It was almost embarrassing how soaked it was, dripping in its overabundance, and he could already feel more sliding out of him to soak his panties now that there was nothing to stop it.
“Alpha’s doing so good for omega,” he praised, stroking his thigh as he began bucking again, clearly frantic with the new scent in the air. “Come on, alpha. Open up, ahhh.”
San’s tongue lolled out without hesitation as Wooyoung reached up, and it took everything not to jump back as he snatched the plug out of the air with a harsh chomp.
And suddenly, his growls became a new mix of whines and muffled yowls and…purring.
San was purring, or rumbling, whichever alphas preferred to call it nowadays. It was all the same. San was sucking on his slick soaked plug and purring in appeasement.
“Mmm that’s it,” Wooyoung praised, returning to stroking him as his hips jerked with less rhythm, clearly more focused on sucking up every drop the omega provided. “Can you knot for me now, alpha? Show me how you’d fill me up and plug me? Don’t you wanna show omega how well you’d breed me?”
San whined again, but seconds later, Wooyoung jumped as a furious howl ripped through the air, just as metal clinked to the concrete beside him and hips bucked forward so hard he nearly fell backwards.
“Shit,” he breathed, but he could hardly even hear himself over San’s yowling dissent, the chains jerking over and over and filling the air with rattling.
Worse. This was definitely worse.
He needed to breed. He wasn’t going to knot until he was breeding properly. And Wooyoung refused to let him do so with one of the innocent omegas outside that door.
It had nothing to do with the fact that he could feel another glob of slick staining his panties beneath San’s primal, hungry gaze. That was just his omega. Wooyoung was stronger than that. It was only for the goal.
“Okay, alpha,” he sighed. “I know. It’s okay. I know.”
So slowly, he pushed his bottoms down until they pooled at his knees, hissing a little as cold air hit his soaked cheeks. San barked a fierce sound, but Wooyoung ignored him in favor of spinning around and sinking to his chest.
“You wanna breed me that bad?” He asked. “Then do it. Give me your pups alpha. Fill me up.”
He was nearly driven off his knees as San bucked against him, and he could hardly stifle the moan in his throat at the feeling of his thick cock and heavy balls grinding frantically against his ass. The alpha howled in some mix of relief and frustration, clearly trying hard to stuff himself inside and failing without the use of his hands.
And just as Wooyoung was about to reach back to line him up for him, he heard that familiar whimper as hot liquid sprayed over his cheeks, dripping down to sink into his stretched, slick soaked hole.
It made him dizzy, his hole clenching wantonly around the new addition.
“Alpha,” he whined, his head fogging ever so slightly. “Knot. Give me your knot.”
And again, San thrust desperately against him, growling and whining and drooling everywhere as he struggled, but the best he could do was snag on his rim before he was popping up again to slide between his plump cheeks.
Finally, Wooyoung reached back, fumbling until he could grab him, and aligning him with his pulsing hole.
He screamed a cry as San drove full in without warning, wasting no time as he began pounding into him without waver. Wooyoung thanked whatever deity blessed him, because if he hadn’t been stretched by the plug, San’s thick cock would have ripped him in half.
As it was, he felt like he was going to burst regardless. San moved at an unnatural pace, leaving the omega to clutch at the hard concrete and wail as he was pounded full over and over. Every drag of his veiny cock along his walls stirred heat higher and higher and higher until he felt like he was suffocating beneath it.
It felt like San was breaking into his stomach, or maybe higher. He could swear he felt him in his very throat as his body bounced forward and back with the power of his thrusts.
“Fu-uck alph-ah ah ah gi-gimme- kno-ot wan’it mnghhh–“
He vaguely heard another whining growl, and felt a hot stickiness flooding into him, but San didn’t slow. And Wooyoung was overwhelmed.
He could feel the way the slide only grew wetter, could feel globs of some mixture of cum and slick sliding out of him and dripping to the floor, could feel San relentlessly fucking it back into him. The sounds in the air were disgusting, wet and smacking, feral and pornagraphic, downright filthy.
Wooyoung couldn’t even hope to stop it as a wave overtook him and he gushed more slick around his dick, spurting clear cum to the concrete below as he wailed something stuck between “alpha” and “please”. Though what he was pleading for, he honestly couldn’t remember.
San was going to break his spine.
As if on cue with the thought, he heard it—the quiet creak just before the gunshot sound of metal spilling and smacking the floor.
He broke free.
He barely had a millisecond to register the fact before he was screaming as San grabbed him, claws burying into his hips and providing a new, horrifying leverage to the alpha’s already brutal pace.
He was on fire. He was exploding. One of the two. Both? He couldn’t say. All he knew was that San was everywhere, flooding through every inch of him as he fucked another pool of cum into him.
“Fu- Sa- ah-a’ph-pha ple-plea-ea-ease can’t! I can’t! I can’t I can’t I can’t I–“
He screamed another wail as he came again, sinking to the floor as his limbs turned to liquid, his own cum squishing against his stomach. But San simply followed, fucking him so hard into the floor that he was certain his tender spots were bruising against the concrete.
For a moment, in his utter delirium, Wooyoung wondered if this had been a mistake. He couldn’t hope to put a stop to it now that San was free. How long would he go for? How rough would he get? This was already enough to destroy him, and something told him it wasn’t even the height of the alpha’s aggression. Would he even survive this?
But those thoughts vanished quickly in the overwhelming sea of pleasure ripping through every inch of him, because god, no one had ever fucked him this good, this rough and hungry. A part of him wanted it to stop because he didn’t know how much he could endure, but a darker part of him wanted the rut crazed alpha to fuck him over and over until his womb was bursting with seed and his mind was slipping away into unconsciousness from overstimulation. Maybe he even wanted San to keep fucking him after it did.
Another wave of cum filled him, making the sounds of San pumping into him at breakneck speed sound no different from stepping into a squelching puddle of mud over and over and over and over. He was certain that if he looked down at his stomach, he would find it bulging with the sheer volume. He was also certain that his ass must look like a damn glazed and filled donut, properly coated and stuffed with the alpha’s milk.
“Kno-ot a’pha knot wan-wan’it gimme p’ease gimme bree-eed me–“
His babbling was barely coherent through his wailing, sobbing moans, but San’s pitched snarling made him think that maybe he understood.
And then he felt it, felt it press against his rim with every deep stroke, felt it pulse and snag whenever it stuffed past only to slide out again, too small to catch—he was finally growing a knot.
And something in Wooyoung snapped, until he was yowling and keening and properly begging, pleading for the alpha to stuff it in, to pop his knot deep in his ass and breed him full.
Even without the audible words, San still seemed to understand, and in minutes, Wooyoung was screaming as he stuffed himself inside one last time before his knot popped and swelled until Wooyoung was certain he was ripping in half. But he could hardly register the pain as he felt that hot stickiness begin to flood his womb.
He purred and whined, shuddering as his cocklet twitched out meager drops where it was trapped between his tummy and the floor, before letting out another scream as San draped over his back and big down hard on the back of his neck just beside his shoulder.
And finally, he felt the alpha collapse atop him, body limp and nearly suffocating, but so pleasantly warm.
He had done it. He had succeeded in breaking the worst of the alpha’s rut. San had finally calmed down.
“Thank you.”
The words were so soft against his ear that he almost missed them, but as the first words he had heard the alpha speak, they rang through the air like marbles on metal.
He couldn’t help the lazy smile that pulled at his lips as his sweaty forehead rested on the cold concrete.
“You’re welcome, Sannie,” he purred back, bringing his arms up to rest his head upon. “Just doing my job. We can train now, after your knot goes down.”
“Silly omega,” came a low chuckle behind him, setting the hairs on his neck to stand just before a scratchy tongue laved over them. “When my knot goes down, I’ll stuff another in you. I’ve gotta make sure my pretty omega’s tummy is all full. How else are you gonna carry alpha’s pups?”
Well fuck.
