Work Text:
Jaemin has always diligently monitored his heats. He’s been using an app to help keep track of his monthly cycle since he first presented as an omega, and he checks it regularly so he knows when to expect the now-familiar symptoms of pre-heat. And for the most part, his cycle is regular, so he doesn’t need to worry about his heat starting without warning.
There are exceptions, though. Nature isn’t perfect, and sometimes, Jaemin’s biological regulatory system fails him. Much to his dismay, now is one of those times.
Jaemin is in the middle of his Architecture 101 class when he starts to feel the telltale wetness between his legs. Upon noticing it, he’s suddenly also hyperaware of his rapidly-rising body temperature, and he fidgets in his seat, fruitlessly trying to keep his slick from making a mess. He can’t help lamenting how unfortunate it is that he’s currently in the most inconvenient location possible for this to occur. This class is the largest one he’s enrolled in, with over two hundred students, and it also happens to be taught by an alpha that Jaemin is unbearably attracted to — the young, handsome, charismatic Professor Jeno Lee.
It’s just his luck that he’s going into heat in the middle of Professor Lee’s lecture, Jaemin thinks miserably, rolling up his sleeves and unfastening the top two buttons of his shirt to try cooling himself down. He’s regretting his choice to sit close to the front of the room, because as much as he likes being able to see Professor Lee’s face clearly, his proximity to the speaker’s podium means that his arousal-heavy scent is going to reach Professor Lee’s nose in less than thirty seconds. And his favorite professor knowing that he’s increasingly desperate to be bred, that his pussy is sopping wet and fertile, is not something Jaemin is equipped to deal with right now.
His anxiety grows along with his need to get fucked. He can smell the interest beginning to radiate from the alphas in his vicinity, can feel their hungry, predatory gazes on him, can hear their quiet growls as they size each other up. Embarrassingly, the instinct-driven omega side of him — the side of him that’s steadily gaining control over his mind as the first wave of his heat really starts to hit — wants the attention, is delighted that there are so many cocks to choose from. That part of him is practically gagging to get fucked by all of them, maybe even at the same time.
Fortunately, the sliver of sanity he’s still clinging to keeps him from giving in to that desire. His underwear and pants are both soaked through now, and he knows that what he should do is leave the room immediately, go home, and use his toys until he’s sated. He can send Professor Lee an apology email after the first wave ends.
But as he stands up and takes a few tentative steps towards the aisle, ready to follow through with his plan, Professor Lee abruptly stops his lecture mid-sentence. Jaemin is properly feverish now, trembling where he stands as sweat drips down his forehead, but he manages to look up at the podium to see what happened. His breath catches at what he finds.
Professor Lee’s eyes are black with desire, his gaze heavy and possessive and fixed on Jaemin. His pheromones are potent with arousal, settling on Jaemin’s skin like a brand, and Jaemin knows, beyond a shadow of a doubt, that Professor Lee is his true mate. And Professor Lee must know it too, because although he hasn’t said a word yet, it’s obvious from his bared teeth and the growls emanating from his throat that every inch of him is screaming “Mine.”
It’s all Jaemin can do to keep himself from stripping bare and getting on his hands and knees to present himself to his alpha in the middle of the lecture hall. He curls his hands into fists, his nails digging into his palms, and bites his lip hard, straining against the urge to bend over his desk and spread his legs. A whimper escapes him as a particularly strong wave of Professor Lee’s scent hits him, tears welling up in his eyes as his pussy throbs with need.
The next thing Jaemin knows, he’s being pressed back against the desk, pinned down by the warm, unyielding weight of an alpha seeking to mate. He recognizes the scent surrounding him immediately — it isn’t a surprise that even the most aggressive of the alphas in the classroom wouldn’t dare try to steal an omega whose true mate is mere feet away, but it is a relief to not be faced with a stranger — and he relaxes in Professor Lee’s hold, heat-drunk and completely submissive.
“Alpha,” he sighs as Professor Lee kisses him hungrily. Even through several layers of fabric, Jaemin can feel Professor Lee’s cock pressing against his pussy, huge and hot and hard. “Alpha, please.” Dimly, he’s aware that the lecture hall is still full, that none of the students in attendance have left, and in fact, many who aren’t even enrolled in this class have trickled into the room after smelling the onset of his heat. They’re murmuring amongst themselves, and some even have their phones out, their cameras trained on the mating pair. As embarrassing as it is, Jaemin can’t bring himself to care.
“My omega,” Professor Lee growls, even as he exposes Jaemin’s chest completely by tearing his shirt off. “Mine.”
“Oh shit,” Jaemin can vaguely hear someone saying as Professor Lee makes short work of Jaemin’s shorts and underwear too. “Is the Prof going to fuck him right here?”
“I sure fucking hope so,” says someone else, and there’s the unmistakable sound of the shutter of a phone camera going off followed by a fly being unzipped.
As humiliating as it should be, none of it matters to Jaemin. The air is concentrated with the scents of two dozen aroused alphas, but all Jaemin cares about is the fact that Professor Lee has just pulled out his cock. Jaemin can’t look away — it’s veiny, rock-solid, and massive. “In me,” Jaemin begs, spreading his legs without even thinking about it. “Professor Lee, alpha, need your cock in me, fuck me, breed me, please.”
“Jeno,” Professor Lee — Jeno — says, rubbing the head of his cock against Jaemin’s swollen, slick-covered pussy without pushing it in. “Call me Jeno, Jaemin. Then I’ll give you what you need.”
Jaemin sobs, trying in vain to coax Jeno’s cock inside him. “J-Jeno, please, need cock.”
Jeno licks a strip along his jaw before biting his neck, centimeters away from where his claiming bite will go after they’ve officially mated. “Needy little omega,” he says as Jaemin cries out and grips his shoulders tightly. “So wet.” He slips the tip of his cock inside Jaemin and groans when Jaemin’s walls clench around it immediately. “So warm and tight, just waiting for me to put my pups in you, aren’t you?”
“Yes!” Jaemin gasps, keening as Jeno thrusts fully inside without warning and begins to move at a merciless pace. Jeno’s cock is far bigger than any of Jaemin’s toys, and the burn is like nothing he’s ever felt before. He’s addicted to it right away. “F-Fuck a litter into me, please, please, alpha, I’ll be g-good, I’ll t-take your knot, f-fill me more —”
“I will, sweetheart. I’ll make sure you’re never empty again,” Jeno promises, using his full weight to hold Jaemin in place as he drives into him without pause, and Jaemin doesn’t bother trying to fight it. He couldn’t even if he wanted to, really, because Jeno is all muscle despite his deceptively slight figure, and anyway, Jaemin’s heat-addled body is more than happy to go pliant in his alpha’s hold and get fucked senseless.
Even Jeno’s cock pounding into him ceaselessly can’t fully distract him from the fact that they have an audience, though. None of the students in the hall seem particularly interested in keeping their presence hidden — their comments are loud and obscene, interspersed with the sound of at least a dozen alphas sloppily jerking themselves off and the occasional click of a camera shutter. Jaemin can hear all of it, and it makes him determined to show off how well he can take Jeno’s cock.
“Damn, Professor Lee is hung. How does he keep that thing hidden?”
“Forget that, are you seeing that tight omega cunt? So fucking filthy and wet, it must feel like heaven. Wish I could stuff it full, I’d love to see that perfect little pussy dripping with my cum.”
“Shit, do you see the way it’s stretching around the Prof’s cock? Fucking vixen, spreading his legs like a professional whore. Bet that pussy has taken dozens of cocks before.”
“What a cockslut of an omega, going into heat in public like this. Probably wanted to get passed around and fucked by everyone here. Just imagine knotting that sloppy cunt after it’s already taken a few loads...fuck.”
“What I wouldn’t give to shove my cock in there with the Prof’s and help him ruin that tight little pussy...”
“Fuck, same...that slutty cunt could definitely take at least three cocks at once. And imagine more cocks fucking that mouth too? Fucking hell.”
Involuntarily, Jaemin’s pussy throbs at the way these unknown alphas are referring to him and his pussy as nothing more than objects to be used for their sexual pleasure. As dehumanizing as it should be, he finds that the prospect of being filled even more than he already is, of being fucked by not just one, but many cocks in all his holes at the same time, is a mortifyingly desirable one. Jeno appears to notice this, because he growls loudly and bites Jaemin’s shoulder again, harder this time, pounding into Jaemin with even more intensity than before.
“Slut,” he hisses. “You’re my omega. The only cock you’re getting is mine.”
“Y-Yes, alpha,” Jaemin gasps, arching off the desk at an especially powerful thrust. “I’m yours, I’m yours, only want y-your cock, I p-promise —”
“Yes, you do,” Jeno says, his tone and scent darkly satisfied. “Now come on my cock, omega.”
It only takes one more well-aimed thrust for Jaemin to fall apart with a cry of Jeno’s name, his nails digging into Jeno’s back as his pussy spasms around Jeno’s cock. Jeno continues fucking him through his orgasm, his lips finding Jaemin’s and muffling Jaemin’s moans.
Jaemin is still trembling from the intensity of his release when Jeno’s hips stutter to a halt and his knot begins to swell. He can only whimper weakly against Jeno’s mouth as hot cum fills him up, the sensation both unfamiliar and addictive. He just came himself and Jeno is still spilling inside him — and yet, Jaemin is already craving another load, already wants to be stuffed to the brim again. He isn’t even sure if it’s just his heat speaking, anymore, because it feels so good.
There’s a visible swell in Jaemin’s stomach by the time Jeno stops coming, and Jaemin stares at it in a daze. He finds himself caught up in a sudden, vivid fantasy of Jeno successfully breeding him on his first attempt, of himself carrying Jeno’s pups. The sharp sting of Jeno’s teeth breaking the skin over his scent gland draws Jaemin back into reality, and he shudders through what feels like another orgasm as his body accepts Jeno’s claiming bite.
“Bite me too, sweetheart,” Jeno murmurs, pressing an unexpectedly gentle kiss to Jaemin’s temple.
Jaemin blinks up at him, surprised — alphas don’t always want their omegas to leave a mark on them in return, but the look in Jeno’s eyes is oddly soft and sincere, and Jaemin can feel Jeno’s affection leaking through their newly-formed bond. With a little noise of assent, Jaemin nuzzles into Jeno’s neck and bites his scent gland, lapping over it afterwards to speed up the healing process.
“Damn, I guess that means Professor Lee isn’t the sharing type, huh?” comes a disappointed voice from somewhere in the room.
Immediately, Jeno growls, his eyes narrowing as he turns towards the student who spoke. Jaemin is certain that if he and Jeno weren’t still tied together, preventing either of them from moving, Jeno would be attacking the other alpha already. Now that the first wave of his heat is receding and his head is slightly clearer, Jaemin appreciates his alpha’s protectiveness in a way he couldn’t when he was overcome with his biological needs. He projects his gratitude and affection through their bond, hoping to soothe Jeno, and is pleased when Jeno not only looks less hostile, but also starts purring, nosing at Jaemin’s jaw tenderly.
Instinctively, Jaemin starts purring back in response, unconcerned with everything that isn’t his mate or the warm embrace he’s huddled in. “Professor Lee,” he whispers, momentarily emboldened. “I’m really happy it’s you. That you’re my mate.”
Jeno doesn’t stop purring, but he frowns for a moment. “Jeno,” he says, an echo of when he corrected Jaemin earlier. “I’m Jeno to you, Jaemin.”
“Jeno-hyung,” Jaemin tries, and he’s amused to feel Jeno’s cock twitch inside him at the honorific. “My alpha.”
Jeno’s frown disappears, replaced by a sweet smile that has Jaemin feeling like a teenager with a crush before he reminds himself that Jeno is his mate and all Jeno’s smiles belong to him now. “My omega.” He draws Jaemin into a long, slow kiss that leaves them both breathless. “I’m glad you went into heat in the middle of my class.” His hold on Jaemin tightens briefly. “Who knows who might have gotten to you first otherwise.”
Jaemin remembers very well the kinds of thoughts that were going through his mind just a short while ago — monogamy was hardly a priority at the peak of the first wave — but he’d like to believe that his desire for Jeno would have won out in the end no matter what. “I still would’ve wanted you,” he says, and it isn’t a lie. He’s wanted Jeno long before today, and going into heat has only amplified that desire.
It seems to reassure Jeno, who licks a stripe along Jaemin’s jaw and nips his earlobe playfully. “Good. Because you’re mine.”
“I’m yours,” Jaemin agrees, squirming a little in place as he feels the second wave of his heat start to approach, just as Jeno’s knot is beginning to deflate. It never fails to surprise him, how quickly the feverish desperation sets in once a new wave hits — his slick is already starting to gush out along with Jeno’s cum. “All yours, hyung. So breed me again, g-give me your pups. Please.”
Jeno’s expression turns slightly feral as he detects the growing arousal in Jaemin’s scent, the steadily-burning desire that Jaemin is projecting through their bond. “Whatever my omega wants. Anything.” He slips his cock back inside Jaemin, pressing deep enough that Jaemin arches off the desk, keening at the stimulation. Someone in the crowd makes a sound, and Jeno’s grip tightens, enough to leave fingerprint-shaped bruises on Jaemin’s hips. “They can watch as much as they want. But only I get to have you like this.”
Jaemin nods weakly, on the cusp of being lost to his heat again. “Only you, alpha.”
Later, they’ll need to address the unorthodox circumstances surrounding their mating — their student-teacher relationship, the audience they inadvertently garnered. But for now, what matters is that Jaemin has his alpha, the omega side of him finally possessed and claimed — just the way it’s supposed to be.
