Work Text:
Kai had a secret. A dirty secret he couldn't share with anyone, not that he had many people to tell in the first place. But nevertheless he had a secret. He liked smelling alphas’ scent at his local gym. The strong musty odor from the men was so intoxicating, enough to make Kai wet in his shorts. He would sniff their belongings, especially their underwear and jockstraps, that's where the smell was the strongest. He would touch himself to it, imagining if the alpha was in front of him, scenting him. It was his naughty pastime that he looked forward to after work, to unwind with the relaxing aromas of a strong alpha.
It was not always like this and Kai wasn't really to be blamed, he did not even know he had a scent kink. He usually wouldn't be caught dead in a gym but his only friend Taehyun needed a gym spotter and Kai couldn't say no to the beta. Working out and plumping his muscles never interested the omega much, however watching alphas get fit was way more up his alley and one whiff of the locker room had him weak in the knees. It was overwhelming even if most of them were wearing scent blockers. The masculine sweat did something to him, something so severe that it made a usually calm and modest Kai turn into a perverted freak that touched himself to smell of random alphas when no one was looking.
As of recently though, he had his eyes set on a certain alpha who frequented the gym around midnight. His name was Yeonjun and his scent has been Kai’s favorite for the past two weeks. Yeonjun was gorgeous with his sexy dark undercut hairstyle and his simple but strong muscles, and pretty lips that almost seemed misplaced on the alpha's face but instead just made him even more stunning to the omega. He always wore black tank tops and loose sweatpants but Kai could still see his cock print if he stared hard enough. The best part was that he didn't wear blockers like the other alphas. It was almost too easy for Kai to memorize the alpha's schedule and locker combination within a matter of visits.
Yeonjun's scent was incredible and Kai was somewhat obsessed with it, mind going dumb from the thought of smelling and sniffing Yeonjun after a long workout. His mouth watering, thinking of sucking his cock, knowing the manly alpha scent would be the strongest there. Instead he settles on the alpha's briefs, he's borrowed a few from his locker. He planned on returning them but he was unable to part with the fabric after a hushed jerk off session while the latter was showering. Yeonjun hadn't reported him yet so maybe he didn't notice and that gave Kai the courage to keep “borrowing”.
Today was no different, Kai left work and immediately went to the gym. Taehyun found it strange that Kai was going so much but not showing any physical improvements but Kai just said that he spent most of the time looking at the alphas rather than getting fit. It was true…mostly. He smiled innocently at the receptionist who was well familiar with his visits at this point and didn't expect anything. Kai knew he had a cute face despite his height and broad shoulders, most strangers assumed him to be a young alpha who would never be up to no good and that's just how he preferred it.
As he makes his way to the locker room, he catches Yeonjun doing leg warm ups by himself near the weight machines. The alpha looked so good, Kai knew he smelled even better especially after he worked out. Yeonjun always sweated the best during leg exercises and it made Kai even more excited to smell his clothing after his workout. He stares until Yeonjun looks into his direction and he immediately speeds walks down the hallway to the locker room. It was funny really, Kai had no problem using the man's scent to get off but looking him in the eyes proved to be a hard task.
Kai lollygags in the meantime, standing next to the water fountain, grabbing a few health bars from the vending machine and playing on his phone until his timer goes off. Like clockwork, an out of breath Yeonjun, holding a water bottle walks into the locker room while Kai’s phone buzzes, alerting him the alpha's workout is finished too. Yeonjun messes with the medicine ball if he's not too tired after leg work but luckily that wasn't the case tonight. Naturally, Kai kept a record of Yeonjun's nightly routine. It told him how soon he'd expect Yeonjun to be finished.
He waits exactly five minutes before he follows him, careful to open the door without causing too much noise and waits. He listens closely and is relieved when he hears the distant sound of the showers running. The omega, now in the clear, walks to the lockers. He spots Yeonjun's locker instantly, he always picks one in the farthest corner and Kai can recognize his lock which had a cute fox keychain attached to it. Kai knows the number code like the back of his hand. Since he began breaking into Yeonjun's locker, the latter had replaced his lock 2 times but his number combination never seemed to change. It made Kai giggle, the sexy alpha really had no idea.
Kai taps in the passcode. 991309. Beep. The lock opens and Kai knows he's in. With the locker door open, the scent of pure Yeonjun surrounds his nose. It made Kai tingly, not only smelling alpha sweat but also the natural aroma of Yeonjun that was just as divine. Cinnamon. Kai breathes it in for a moment before going back to the task at hand. He digs through Yeonjun's gym backpack and doesn't have to look too hard to find what he desires.
Yeonjun's used gym clothes. Kai brings the crotch area of his loose workout pants to his nose and audibly moans. He moves to his briefs and his knees buckle, the bench catching him from falling on the floor. His manly scent was most potent there, leaving Kai desperate for more of it. He'd usually just take the used underwear and leave but…
Kai cautiously looks behind him, wondering if he would have enough time for a quick jerk off session. There was no way he could wait, feeling slick seep from him. Yeonjun's showers were usually 10-15 minutes. A few deep sniffs with his hand on his dick would be enough, it's all he would need.
Kai haphazardly shoves his hand into his shorts, grasping his length tightly. He moans into the fabric as he breathes in the raw manly alpha odor. It was amazing, so good. He fucks his hand, as the aromas completely take over his mind, a feral desire to come taking front attention for him. Unfortunately, he fails to notice how long he takes and…
“Caught you~" a warm voice makes Kai snap out of his trance. He swings his head back only to be greeted with Yeonjun standing behind him. His eyes are on Kai, arms crossed against his bare fit chest.
Kai jumps to his feet in shock, turning around to face the alpha. “I-it's not what you think!" he squeaks.
Yeonjun scoffs. "Really? ‘Cause it looks exactly how I think.” He stalks over wearing only a low towel around his waist and punching his hand into the locker next to Kai’s head, the omega yelping. "You're the degenerate who's been stealing my used underwear.”
Kai can't deny, not when he still had a pair in his guilty grip so he nods his head in shame. His heart was beating so fast and having Yeonjun in his personal space only accelerated it. He wanted to run but he couldn't. Not with Yeonjun focusing on him.
“I-I'm sorry-ah!"
Yeonjun's hand wraps around Kai's neck tightly, slamming his head against the locker. It leaves him no choice but to look Yeonjun right in his spectacular face.
"Sorry? Sorry people don't beat their cocklets to a random alpha's scent, you perverted little freak! The fucks the matter with you?" Yeonjun snares, showing his teeth and Kai has a hard time getting his words out right because holy shit Yeonjun is addressing him but he's also so pissed yet that it does nothing to ruin his arousal. In fact, Kai leaks more in his gym shorts.
“You know, I had a suspicion someone was breaking into my locker, touching and stealing my used sweaty clothing because it had an unfamiliar sweet scent on it. Then I realized that everytime I’m at the gym, you are too. Whenever I use the locker room, you aren't too far away either. That's why I decided to set a trap and you fell for it like the pathetic freak you are.”
Kai gulps, the alpha had him all figured out, but how? He has been so careful until now.
“I-I'm sorry?" Kai says but it comes out as a question while his brain tries to pinpoint when he became so careless in his favorite secret pastime.
Yeonjun scoffs again, tightening his grip on the omega’s neck. “That's all you got to say for yourself? A useless apology that we both know you don't mean? I thought omegas were supposed to have more decorum. Explain yourself and maybe I won't crush your windpipe.”
Kai gasps, coming back to his current situation at hand. Yeonjun was threatening him but all Kai could do was submit to the alpha, completely puddy in his hold. “It's just... your scent smells so good, it's intoxicating! Especially when you sweat. I couldn't help myself! I had to have more!"
"Disgusting dog." Yeonjun deadpans. "You don't know me at all, not even my name and yet you do this. You're really a one track mind pervert.”
“T-that's not true!” Kai interjects. "I-I know your name is Yeonjun Choi and you work out every night. Usually around midnight and-”
“Shut up." Yeonjun rolls his eyes and Kai immediately clams up realizing speaking wasn't really helping his case. He looks at him with a disbelief smile. “Not only are you a perv but you're been borderline stalking me. You really don't have any shame at all huh?”
Kai bites his bottom lip, looking down and just now realizing Yeonjun is staring nearly chest to chest in front of him practically naked, getting high off his scent. His eyes trace over his pearl skin, still glistening with sweat and stream. Yeonjun must have caught Kai right before he took his shower. Kai inhales deeply, humming. Yeonjun’s natural musk beats the sweet and flowery smell of soap anyday.
“Fuckin’ pervert. You really don't have any shame, still gawking at me even after I caught you red-handed. You're pathetic scum." Yeonjun spits, scowling. Kai licks his lips, looking up at Yeonjun once more.
“I-I'm sorry, you're just so beautiful and gorgeous and you smell so good-”
"What's your name, freak?" Yeonjun asks, interrupting Kai’s ramble.
“I-I'm Kai." he swallows, shivers knowing Yeonjun likely felt the action through his palm.
“So Kai," Yeonjun starts and Kai flushes from the way his name sounds coming from the alpha's mouth, making him want to drop to his knees and pledge his obedience to the alpha. “You think I'm beautiful?"
Kai attempts to nod but Yeonjun holds his head in place, squeezing his neck. “Use your words, freak.”
“Y-yes alpha.” Kai responds to his best ability and his heart races when he sees the upwards twitch of Yeonjun's lips at the way he addressed him.
“And you like my alpha scent, yeah?"
"Yes alpha. It's the best thing I've ever smelled.” Kai confessed and Yeonjun stared at him, like he was trying to figure him out.
"Despite your obvious degenerate qualities, you're kind of cute and I admire your honesty, omega,” Yeonjun smirks, loosens his grip on Kai's neck and Kai immediately mourns the pressure, feeling bare and shy that the alpha called him cute. “So I'm going to be nice and give you a treat.”
Kai is confused, not knowing what was going to happen next. He watched Yeonjun like a thirsty man in a desert in desperate need of water as the alpha slowly backed away, undoing his towel with a knowing grin on his face. The towel drops and so does Kai’s mouth, staring at the gorgeous inches of Yeonjun's naked body. His cock was perfect, half hard and thick. Yeonjun sits on the bench with his legs spread, waiting.
“Go on, sniff me all you want." Yeonjun says, an invitation.
Kai’s head is so fuzzy, has to fight the feeling of his knees buckling and his heart stopping at the sight. Instead he drops to his knees in front of the alpha. His scent makes Kai's mouth water. He balances himself on the bench as he sniffs Yeonjun's neck, openly moaning happily. He kisses and licks at the slick skin there, so badly wanting to leave bite marks.
“Can't believe you're really like this. You're such a nasty little freak.” Yeonjun comments as Kai moves his attention to his muscular biceps. He lets the omega lift his arm and is amazed as Kai buries his nose into his armpit.
Kai whimpered helplessly, licking and sniffing the sweaty odor of Yeonjun's pits. It had to be the second place on the alpha's body where the scent was so powerful. Yeonjun didn't have any hair under there, freshly waxed but if possible his manly smell was even stronger.
“So good, a-alpha," Kai mumbles, practically making out with the armpit before begrudgingly releasing it to give the other pit the same treatment.
Yeonjun doesn't offer any sounds of encouragement or distain to Kai's desperate behavior. Once Kai finishes his worship of his second armpits, he moves to Yeonjun's chiseled chest. He thumbs out his pecks, glistening with water drops. Yeonjun's nipples were light brown and hard. Kai presses sloppy kisses to both, flicking his tongue over them before pulling off with an audible pop. He peeps up at Yeonjun then, curious to see if his actions were having an effect on the alpha. Despite the hardening of his nipples, Yeonjun held a neutral, borderline bored look on his face.
“What, did you expect me to find this arousing? A pathetic omega mutt licking all over me?” Yeonjun scoffs meanly. "I'm doing an act of charity by even allowing you to do this. It doesn't bring me pleasure at all."
Kai should feel insulted and humiliated and maybe he does but it's drowned out by the desire to make the alpha feel good. He wanted to bring Yeonjun the pleasure he was granting Kai by simply allowing him to touch the alpha. Kai looks back down, kissing every cease of Yeonjun's taut muscles, breathing in deep. His scent was growing stronger.
“Don’t you have any manners? You still haven't shown your appreciation yet.” Yeonjun comments and spreads his legs further; another invitation, if not a little less subtle.
Kai may be feeling a little out of it because of the pheromones, but he still manages to focus on Yeonjun’s cock and actually whimpers when the length is right in his face. The alpha's cock was perfect, thick and heavy in Kai's hand but it's the scent that made his mouth water. He smelled so intoxicating, Kai could die right now and would be a very happy man.
He meets Yeonjun's eyes once more, while stroking the length. “T-thank you for the meal alpha," Kai says and greedily licks the head, pressing kisses along the side before sliding his wet tongue over it. He could taste the musk still on Yeonjun despite him showering. It's incredibly hot. He wished he could spend hours just worshiping and licking his cock but he had an objective. He wanted to make the alpha feel good too.
Yeonjun grunts as Kai drives in, slurping his tip into his warm mouth. He flicks his tongue out fast, tasting Yeonjun's sticky precum. The alpha hand reaches out for the omega’s locks, tugging on them roughly.
“Fuck," Yeonjun pants, when Kai licks up his cock underside. He pulls the omega by the hair. “Hey I said show your appreciation, not tease my cock.”
“Hmp!" Kai gasps, Yeonjun shoves his head down, forcing him to take his entire length down his throat. He quivers, and fights his body's instinct to break free, struggling to breathe. The pure, unadulterated scent of the alpha's aromas fill his nostrils as his pubic hair tickles his nose. He never smelt something so intoxicating in his life. Kai feels slick fill his shorts as his cock throbs.
Yeonjun doesn't wait long until he begins fucking Kai's mouth, who is
helpless to the alpha musk omitting from his cock. He lets Yeonjun set the unrelenting pace while loosening his jaw and staring at the beautiful man in front of him.
"Disgusting whore." Yeonjun spits. He uses his foot to keep Kai's head down, deepthroating his length. Kai drools more, and lets the alpha use his mouth. Unshed tears fill the corners of his eyes but he's so turned out, he might die of happiness. “Such a cockslut. Should I knot your mouth pussy? Fuck, you'd take it like a good toy, wouldn't you dog?”
Kai only responds with a mix of a sob and moan. He'd be a dog, be the best doggy for the alpha if this is what he gets as a reward. He was a mess in his pants, a definite wet spot in the front and back of his black sweats. Kai rests uneasy hands on Yeonjun's thighs for balance, the position has his ass perched and Kai’s wet hole grasps around nothing, lusting for the same cock that was currently bruising his throat. A constant flow of slick seeping out while his cock was dripping precum like a broken faucet.
Yeonjun smirks, pressing his foot hard against Kai's boner. “Look at you, getting turned on with an alpha dick in your mouth and my foot on your pathetic cock. You really have no dignity.”
The constant pressure to his leaking cock, along with Yeonjun's incredible musk is too much for the omega. Kai gags, mouth full of thick length as he creams his shorts untouched. He moans shamefully then, his legs twitching as he thrusts into the air to chase his release.
“...Did you just come?" Yeonjun questions, tugs Kai's lull head off his cock, drool connecting to his mouth. His eyes were low lidded and his lips puffy from Yeonjun's mean treatment. “Wow, you really are nothing but a dirty pervert. You couldn't even get me off first. Selfish slut. Now you have to make it up to me.”
Yeonjun stands up and points to the bench he was sitting on, Kai follows his movement with a tilt of his head. “Present yourself." He demands, the omega scrambles to follow his order. He follows his sub gender’s instincts and gets on his hands and knees, his ass facing the alpha. Yeonjun pulls his shorts down and Kai's vanilla omega scent instantly becomes heavy in the already heedy locker room. He growls, staring at Kai's round ass, slapping it just to see the cheeks jiggle. Kai moans wantonly, relishes in the sting, silently begging for more. “Of course you like this. You'll take whatever I give you with a smile.” Yeonjun chuckles deeply and slaps his ass again and again and again, until Kai’s cheeks have the faint outline of the alpha's palm.
Kai can barely see, his eyes filled with tears of ecstasy. His ass was throbbing red but he just wanted more, thought he would die if the alpha didn't fuck him. His hole grips around nothing, slicking making a mess down his inner thighs. The alpha and his scent was making Kai insane with lust, reckless even.
He arches his back, spreading his ass cheek, giving Yeonjun a clear view of his glistening pucker.
“Yeonjun alpha, stuff me with your cock. I want it so bad, please fill me,” Kai pleads desperately, the rest of his self respect is thrown out in hopes of being claimed by the alpha. There was nothing he wanted more in that moment.
The alpha curses under his breath and Kai feels the stiff pressure of his cock head on his taint. Yeonjun taps against it a few times. “You just met me formally and you want to be fucked.” He sucks his teeth but he doesn't sound annoyed or grossed out like earlier. Rather, his voice was thick like honey, completely affected by the omega. “Just how long have you been fantasizing about this very moment pervert?"
Kai gulps. There was no point in lying at this point. “S-since I first smelled your scent. I got off thinking about you fucking me and claiming me."
"Is that right? Aww you poor puppy. Well lemme help you then since you're being so obedient.” Yeonjun holds Kai's lower back, getting a good grip on his hips. He rotates his tip against the hole, mixing slick and precum. He abruptly shoves his cock right in and Kai screams at the sudden intrusion. Yeonjun immediately gains a fast tempo, the wetness making the slide easy as Kai's walls tighten around the alpha.
“Ahh A-alpha!" Kai cries, the big dick stretching him with ease and his body slowly adjusting to the alpha's size, he was really having sex with Yeonjun. He would think he was dreaming if not for how full he felt.
Yeonjun grunts, picking up his pace. “I thought a perverted slut like you would be used to taking dick, but your bussy is gripping me so tightly.”
Kai moans, shaking his head. “N-no alpha. You're the f-first alpha I've taken, I promise.” he confesses. He had taken a beta once or twice before but the distinction was obvious. None of them could compare to alpha cock, Yeonjun's alpha cock.
Yeonjun pulls out suddenly and Kai is babbling for more even as the alpha turns him on his back, practically ripping his shorts down his thin legs. He takes in the view in front of him. Tousled bangs sticking to his forehead, his face is rosy with arousal and his pink mouth parted. He had delicious omegan proportions, with a busty chest, small mid drift and curvy hips.
“Perverts are supposed to be grotesque. You have no right being this sexy." Yeonjun huffs and tugs Kai's sweatshirt over his head, tossing it on the floor with the shorts. He groping his way downwards on Kai’s chest and omega feels a little embarrassed being completely laid out bare in front of the alpha of his fantasies, especially with Yeonjun's wandering eyes. It was too much and Kai is about to ask for his cock again but the alpha beats him to it, spreading his thick thighs and thrusts back into the omega’s sweet heat so he just moans instead. Kai was so glad the bench was screwed to the floor or else he would have fallen with how hard the alpha was fucking him.
The omega is loud, can't hold back as he falls apart getting fucked so good, drool sliding down the side of his mouth. Yeonjun stares at him with dark eyes while he rams into his addictive hole. It was kind of scary but mostly alluring as hell because his alpha aroma was rolling off him in waves that left Kai completely intoxicated.
He can't stop himself from talking. “Alpha…so good…fucking me so good. Always wanted ah your cock-ah harder alpha-!”
Yeonjun’s hands wrap around his neck, holding stern and slowly applying pressure. Kai gasps, his cock throbbing as he is choked and fucked. He watches Yeonjun's handsome features with blown eyes. So dominating, Kai would present his neck if he could. Yeonjun bites his bottom lip and leans down until they are centimeters apart. Kai's breath hitches, thinking that Yeonjun would give him a kiss but he never closes the distance between them. It is then, the alpha spits directly between his parted lips. Kai makes a shrill sound, in partial disbelief that the alpha spit in his mouth. Nevertheless, he gulps it down with a moan, feeling warmth fill his chest from taking what Yeonjun gives him.
He doesn't even realize he's coming again, white spurts hitting his tummy. Yeonjun fucks him through it, comments on it with a snare. “Dumbslut omega coming from being fucked and abused. You really are a lowly whore.” His thumbs cover Kai's nipples and tugs on them hard.
Kai squeals, throwing his head back. His nipples are a highly sensitive zone for him and Yeonjun picks up on that because he continues to pinch them. “I'm sorry… alpha's cock is so good. Better than I could imagine,” Kai confesses and the damning smell of Yeonjun's alpha scent is in full effect.
“Bet you'd let me use you like this, before and after my workout, you'd spread your legs and lemme you fuck your needy bussy.” Yeonjun pants between thrusts.
"Ah-anything…anything alpha!" Kai shrieks, drool rolling down his chin. He felt so good, he didn't want it to stop. Not until he was properly bred and knotted by the alpha of his dreams. “I’ll do anything you want."
Yeonjun groans, slamming into the addicting heat. Loud wet slaps echo throughout the locker room as well as Kai's unabashed moans.
"Good. You're my omega sex toy from now on. That means, you're gonna let me fuck you whenever I want it, understand?”
“Yes! God, yes alpha, please knot me, please claim me. I'll do whatever you want. Please make me yours,” Kai pleads, and it almost sounds like a love confession even though in that moment Kai swears he loves Yeonjun. He bears his neck, feeling the alpha's cock pulsating inside him. He wants it, wants his come so bad, he can almost taste it.
“Fuck, you're mine now Kai,” Yeonjun groans, nearly covering the omega with his form as his thrusts slow down in pace. He shoves his cock ball deep inside and Kai quivers, his knot expanding in his used hole. Yeonjun licks over his neck before plunging his teeth in, breaking skin as his cock is milked thoroughly.
Kai moans weakly, coming dry from the feeling of being claimed and knotted by Yeonjun. He's overly sensitive now but he can feel the hot alpha painting his hole white. He closes his eyes, smelling a raw mixture of both their scents. He sighs and gives himself to the utter bliss he felt at that moment. Yeonjun licks over the claiming bite once more and watches him, silently while catching his own breath.
“Hey, don't pass out now," Yeonjun hits the side of Kai's face. He looks tired himself.
Kai blinks his eyes, pouting a little. "I wasn't sleeping alpha.” He tests the give of the knot, finding himself still connected to Yeonjun. He smiles dopey, feeling bold and runs his fingers down the alpha's bicep. “Do you forgive me for being a dirty pervert?”
Yeonjun scoffs but he is failing to fight off a smile even as he grabs Kai by his jaw. “You came more times than I did, you think that's fair? If anything, you owe me more now than before. Besides…” Kai blushes as Yeonjun brushes their lips together, a lazy makeout session and out of everything they just did, this part is the most sweet for the omega.
"You're my omega toy now and I'll even let you continue to touch yourself to my scent. You just have to do it in front of me.” he smirks.
Kai couldn't believe his ears, could he really be so lucky…?
"Understood alpha."
Yeonjun gives him another fleeting kiss and says, “Good. When my knot goes down, don't shower. I want everyone here to know you're my property. Then you're leaving with me.”
“W-with you?"
"Yeah, you'd like that, don't you?”
And yes, Kai liked that very much.
