Work Text:
Katsuki sighs as he steps out of his car for work, shoving his keys in his pants pocket. It wasn’t a hot day, but a thin layer of sweat sat uncomfortably on his neck, trickling down his shirt. He walked into the office, passing the front desk and making his way to the elevator. The intern he’d hired a week ago holds the door open for him as he walks in.
“H-hello sir, good morning-“ the boy stops mid sentence, nose twitching as he sniffs the air. “Are you feeling all right Mr.Bakugou?” The boy asks, light blush coating his neck. Katsuki’s eye twitches, already annoyed at his hot flash that refuses to go away.
“I’m fine,” he growls. “I’d be even better if I wasn’t on this fucking elevator with you.” he says as the elevator stops at his floor and he trudges his way to his office. He slams the door shut behind him and begins on his work.
It takes five minute for him to get up and turn up his air conditioner, and another three before he shifting around on his seat. His face flushed from heat and something else. He’s be lying if he said that he couldn’t feel the growing warmth in his lower stomach, the way his small omegan cock tried to tent his pants, and how his cunt was beginning to dampen his underwear. He panted as he clawed at his clothes, wishing desperately that he could take them off, but knowing he was still at work. He knew the implications of his situation. How they aligned almost perfectly with the signs he’d felt before his past heats. But he’d been on heat suppressants since he was nineteen and they’d never failed him.
A knock at his door had him groaning as he tried to compose himself.
“Come in,” he said, breath labored and slightly higher pitched. His friend slash coworker came in and immediately recoiled.
“Um Bakugou, I came in because you have a meeting scheduled in fifteen minutes. But I think it’s a better idea if you go home. Your heat has clearly started.” Katsuki just rolls his eyes at the younger man’s words.
“I took my heat suppressants yesterday, that’s impossible.” The boy just gives him a sideways look, clearly not impressed by his flushed face and labored breath. The beta before him was having trouble breathing too, his shirt bunched over his nose.
“Look sir, I really think you should go home. The office really doesn’t need any… incidents.” Katsuki knew what he meant. Hell, he was the one that had to write the incident reports. Many alphas didn’t have enough restraint to ignore an omega in heat, their instincts taking over as they had their way with the hormone stricken omegas.
“Kami,” Katsuki whispers, surprised by his own pleading tone. “F-fuck, I dunno what’s wrong. I shouldn’t even have a heat.” He digs around in his desk for the extra heat suppressants he kept in there. Reading the packet, the blood drains from his face, filling somewhere he wishes it didn’t. “They’re,” he swallows harshly, “they’re expired. They expired in august.” Denki swallows, coming all the way in and shutting the door so his sent didn’t leak onto the halls too much.
“I- I’ll call your alphas. They’re not too far, right?” The fog in Katsuki’s brain is growing thicker, and he can only whine. Kaminari takes out his phone and dials a number. “Kirishima… yeah I’m good but Katsuki… his heat started.” A long pause. “He’s in his office… no nobody has tried to come in… yeah he’s safe.” Another pause. Kaminari pulls the phone away from his ears and puts it in his pocket. “Kiri says that he and Midoriya will be here in about thirty minutes. Will you be… alright till they get here?” Katsuki just whines moving from his chair to the cold white stone tile. He sighs as the coolness of the tile rushes onto his hot skin. He whimpered as the his pants began to dampen, his hard cocklett rubbing against the floor. “Katsuki, come on stop that. Your alpha’s are on the way, just hold on.”
As if his body just remembered the other person in the room, his lower half began to throb.
“Kami," he whined pitifully. He crawled over, pawing at Denki’s lap. The beta let out a squeak backing away from the other. “Please Denki. ‘M so wet. Promise I’ll make you feel good.” The betas pupils were dilated and he panted softly.
“You don’t know what you’re doing Kats. I promise your alphas are gonna be here soon, just wait for them.” Katsuki just nuzzled into the man, keeping his hands to himself but drinking in the betas scent. Kami just gulped as the man cuddled up to him, trying to keep as much space between them as possible. Kaminari groaned deeply as Katsuki began to grind his clothed cunt on his leg. The scent of the omegas slick began to soak into the betas sweatpants, the warm liquid pressing into his leg. “Katsuki stop, please.” The beta grabs the man’s hips, stilling his motion. Katsuki just whines, trying uselessly to buck his hips.
He opens his mouth to complain when he freezes. His nose twitches as he faces towards the door, eyes widening. Quickly, he scrambles towards the door, throwing it open the same time his alphas reach it. Their pupils are blown, growling as they grab their omega.
“Fuck Katsuki,” Kirishima growls, “you smell so fucking good.” Izuku buries his nose in the man’s neck, licking over the faded bite marks.
“Oh baby, we’re going to fucking ravage you.” Katsuki just whimpers as he’s picked up bridal style. Kirishima said something to Kaminari, but his brain was too foggy to pick it up. He barely remembers getting to the lobby, his alphas carrying him out the building and into the car. He’s distracted by Izuku’s lips on his own for the whole ride home, and when they arrive, he’s carried all the way up to his bed.
He’s sat, basically thrown, onto the bed, his alphas crawling up next to him.
“We were so worried about you,” Kiri says, crawling on top of him, sucking bruises into his neck. Katsuki whines, rutting his clothed cunt on the thigh between his legs.
“N-need you,” the omega whimpers. Izuku sat him up, sliding behind him.
“You don’t know how scared we are when Kaminari called us. We thought something might’ve happened to you.” Katsuki could smell a hint of fear woven through his alphas scents.
“Everything’s fine,” he reassures, “'M fine. Jus' r'lly fuckin' horny.” Eijirou chuckles into his ear, blessing a soft kiss into his neck.
“We’ll help you out baby, don’t worry.”
Katsuki moaned as two rough fingers slipped into his warm cunt. “W-wait Kiri,” he gasps, squirming in Izuku’s arms.
“It’s all right baby, let us take care of you.” Katsuki just whimpers, sagging Into his other alphas embrace. Said alpha sucks angry red marks into the man’s neck, reaching his hand over to stroke the omegas small cock.
“A-alphas I can’t take this. Just fuck me, please!” His alphas ignored him, continuing to pleasure him relentlessly. He came with a drawn out groan, spilling warm cum into Izuku’s hand and clenching down on Kirishima’s fingers. He panted, opening eyes he didn’t realize he’d closed. His cunt was still wet however, and he planned on making it his alphas problem. He started grinding down on Izuku’s hard cock, drawing a growl from the man’s lips.
“You’re really playing with fire there, darling,” the man says in a deep voice. He ignores him, turning attention to the alpha in front of him. He unbuttoned his pants and slipped him out of his underwear, taking his heavy cock in his hand.
“Fuck baby,” Eijirou groaned as Katsuki began to stroke his dick. The omega didn’t listen, grinding down harder on Izuku’s cock and coating his hand with spit, stroking Kirishima faster.
Izuku came first, bucking into Katsuki and spilling a harsh load into his sweatpants. Kirishima was next, hips stuttering as he spilled into Katsuki’s hand. Katsuki shifted so both his alphas could see him, bringing his hand to his mouth and licking his fingers clean of Kirishima’s cum. He’s being picked up in seconds, placed so that he’s straddling Izuku’s lap and pressing his ass again Kirishima’s cock. Izuku quickly rids himself of his pants and lines himself up with Katsuki’s cunt. He rubs his cock against the smaller boys pussy, eliciting several small moans from the man. He begins slowly working himself inside the man, groaning at his tight heat.
“God baby look at you. Swallowing my cock inside your greedy fucking cunt.” Katsuki let out a high pitched whine, grinding down on the fat cock stuffing his hole.
“A-alphas please,” he moans. “I need you both. Need you to fill me up till I can’t take anymore.” Kirishima growls from behind him thrusting his cock against the omegas soft ass. He reaches a hand around to give a quick couple of stokes to the man’s cock, then going down to rub his clit.
Katsuki moans as Izuku begins to fuck into him, Kirishima moving from his clit to slide two fingers into his as well. Katsuki moans loudly, whining as he’s pleasured by his alphas. He can’t help but bounce on Izuku’s cock and Eijirou’s dinners as he chases his pleasure.
“Alphas please!” He shouts, leaning back against Kirishima chest. The man turns his head bringing him into a deep kiss, sliding his tongue in the omegas mouth. Katsuki moans, allowing his mouth to be dominated by the alpha. “R-ravage me, Ei.” Kirishima can’t help but groan, removing his fingers from the boys hole. Katsuki whines, the feeling of Midoriya’s cook not enough to keep him satisfied.
“I need more Kiri!” The man gives a deep chuckle.
“Don’t worry baby, we’ll give you all that you need.” Izuku grunts in agreement, continuing to fuck into the needy omega. Katsuki can’t help but gasp as he feels something poke at his cunt, slowly working its way inside of him.
“W-wait Kiri, it won’t fit!” The alpha ignores him, continuing to push his cock into the omega. Katsuki can’t help but moan, clenching around the cocks buried in him as he orgasms, falling against Izuku chest.
Sandwiched between the men, he can’t move as he’s fucked into. Both cocks hammer his g-spot, as he unraveled between them. He’s a buddy of moans and sobs, unable to move as he’s used for his alphas pleasure. Another orgasm is ripped out of him before Kirishima adjusts their position. Now, he’s placed on both the men’s lap as Izuku uses his brute strength to bounce the omega on both of their cocks. Katsuki is completely fucked out, eyes crossed and half lidded, tongue lolling from his mouth.
“Look at you baby,” Kirishima grunts. “Just getting fucked stupid on me and izu’s cocks, huh?” Katsuki can only whine, falling back onto Kirishima chest. Izuku’s thrusts begin to get more erratic as he struggles to keep up Edith Kirishima’s pace.
“God baby,“ he moans. “Can’t wait to cum in your tight pussy. See you full of me and Ei’s cum when we fuck you full.” Katsuki moans as Izuku comes undone, bucking his hips and spilling his load into the omega. Kirishima comes a few minutes later, biting into the boys shoulder as he fucks his cum into the boys tight heat. Katsuki can only remember him clenching down in his final orgasm, clear liquid gushing from his cunt. Then, he collapses into his alphas arms, and falls asleep.
When he wakes up, it’s to his alphas’ embrace. There both sleep, peaceful expressions making the omega smile. He can only smile, content to sleep in his alphas arms, knowing the days of fun and passion that are soon to come.
