Work Text:
Katsuki is… tired to say the least. His day had been dragging on since he woke up at his usual five a.m. start time, organizing his day as he sips on his morning coffee. Usually he has a secretary to take care of the nitty-gritty details, but he had given her the entire day off as it was Valentine’s Day and she was planning on proposing to her omega today.
The blond sighs to himself as he struggles to pull up his digital schedule, glancing over it as the soft sizzle of his breakfast goes off in the background. Several meetings, a call to their cocaine supplier, a torture session for information about the russian gang that had recently encroached on their territory… an entirely booked day.
Just the way he likes it.
Of course, if he had been mated, he would be taking the day off like his secretary. But in the thirty-something years that Bakugou Katsuki had been alive, he had never even gone on a date. He constantly justified this to himself as just a casualty of the job, pointedly ignoring the fact that almost all of his subordinates had their own partners or mates. Of course they did, they didn’t have half the responsibility that he carried on a daily basis.
So when he walks into the building that morning, he’s not surprised to be bombarded by almost all of his newer recruits trying to set him up on a date with either themselves or a family member of theirs, sometimes even offering him their mates.
“Oyabun!” Cheeks calls, shoving her dirt-brown hair behind her ear, “I’m free this evening if you aren’t busy. Maybe we can go to the new bar down the street?”
“Oyabun, sir, my sister just got dumped by her previous alpha, maybe I can introduce you?” One of the blond alphas speak up.
“Oyabun, are you busy later? My omega would love to meet you.” Glasses makes hard eye contact with him, almost not backing down as Katsuki pushes through the small mob that had formed around him.
“Everyone! Leave Bakugou alone,” Kirishima calls from the side, “I know you all have assignments, and if you don’t get them done, you can be put with our ‘friend’ in the chamber.” The group quickly scatters, though Cheeks still throws Katsuki an off-handed wink as she heads off with two alphas, off to start their usual antics as distractions for the more skilled thiefs in the operation.
“Bro, we need to find you somebody to ward off all the desperates,” Eijirou chuckles, swinging an arm around Katsuki’s neck, “I’m surprised you haven’t accepted even one of their offers yet, I know you aren’t getting out on your own.”
The blond snarls, not seriously but enough to make the redheaded alpha back down slightly. “I don’t have time to go out, Shitty Hair. I take care of everybody else’s mistakes all day, every day. Even if I wanted an omega, I couldn’t go out and court one without being worried about their safety.” Katsuki rolls his eyes, shrugging off his lieutenant’s arm as he straightens his suit. “I’ll be fine. I’ll pass the role of oyabun to one of your pups when the time comes, considering I’ll never have any of my own.”
Kirishima huffs, a stupid idea appearing in his brain as he watches his boss walk away. He smiles to himself, turning to walk in the opposite direction as he pulls out his phone to call one of their many subordinates.
“Hey, Dabi? Yeah it’s Kirishima, I have a random question… how many omegas do you have in stock?”
Later that same night, as Katsuki came into his penthouse, he could hear the softest vibrating noise from deep in the apartment. The blond deeply inhales, immediately catching the scent of an omega in heat but he doesn’t even want to know what it is, too tired to even speak as he dropped his work-bag on the kitchen counter.
He ignores it as he walks through his bedroom, seeing a tied-up omega whimpering and sobbing on his bed. The buzzing noise is louder here as his eyes dart to the shaking form, trying to find the source of the incessant sound. A bullet vibe is taped to the omega’s little clit, their pussy on clear display as they’re tied up in a presenting position. Legs forced apart by a spreader bar, hands bonded to their thighs, with a ring gag forcing their mouth open and a blindfold tied tightly over their eyes. And finally, a pretty red letter taped on directly on a bare, freckled cheek of the omega, simply addressed ‘Katsuki’.
There's a large puddle of slick wetting his sheets directly below the omega, and Katsuki can’t help but huff in annoyance as he snatches the letter, ignoring the whine of protest from the in-heat bitch.
‘Katsuki, take this omega as a gift for Valentine’s Day. Enjoy yourself for the first time in years, and if you decide to keep him, that’s totally okay! He’s directly from Dabi, I know you don’t like the man, but he has the best omegas for purchase. The omega is new, still pure, and only just presented within the last two weeks. I know you like them young— he’s still in middle school. I hope you enjoy him. Happy Valentine’s Day.
Love, Eijirou.
P.S, his given name is Izuku according to Dabi, but since he was ‘picked up’ without identification, we can’t find his last name. Maybe he’ll tell you after you break him in properly?’
Katsuki growls annoyedly, throwing the letter to the ground as he fishes out the other thing in the envelope.
A fucking lollipop. In the shape of a heart.
Gross.
The blond still unwraps it anyways, shoving it in his mouth to get it wet before stuffing it inside the little omega before him. ‘Izuku’ quickly clamps down on it, his cunt visibly quivering as he orgasms simply from the lollipop entering him and…
Bakugou hates that he’s turned on. Hates that his best friend knows him that well, to go as far as ordering from one of the few people in the underworld that Katsuki straight up didn’t trust, just to get him laid. Which he obviously needs, if the pressing boner in his suit pants was anything to go by.
Katsuki can’t help but to quickly strip, feeling the guilt settle deep into his stomach as he watches the whimpering boy shudder and shake from the constant vibration on his overstimulated clit. The stick of the lollipop still sticking out of the boy’s cunt, slightly quivering as his channel tries to suck it deeper inside him.
As soon as the alpha is completely naked, he’s clambering up onto his bed behind the needy omega, hands starting to trace every inch of bare, pure skin.
Izuku has freckles everywhere . It’s incredibly endearing and Katsuki gives himself a moment to appreciate the little things about the tiny omega. Pressing red-hot kisses against every freckle that graces the boy’s ass and thighs before finally, finally slipping the lollipop out of Izuku’s pussy.
He leans fully over the omega, twirling the lollipop between his fingers as Katsuki brushes a few stray curls out of Izuku’s face. “Do you want it off, omega?”
The teen quickly nods, drool pouring out of his open mouth. At this point, his brain is completely gone, making him complicit to whatever Katsuki deems to do to him. The alpha quickly complies, easing the duct tape off of the omega’s eyes before relieving him of his gag.
“There we are,” Katsuki coos, “Are you gonna be good?”
Izuku nods once more, blinking slowly as he tries to adapt to the sudden light. His pupils are blown wide, so deep into his heat that he doesn’t even seem to notice as Katsuki slowly slides the slick-covered lollipop between the omega’s petal pink lips.
His instincts must kick in though, because he’s immediately hollowing his cheeks, sucking on the candy like it’s a cock. He doesn’t even struggle as Katsuki resumes his position behind the teen, content to sit there and take whatever is given to him.
The alpha growls appreciatively as he spreads Izuku’s cheeks, forcing his hole on display as Katsuki’s bobbing cock ruts against the wet entrance.
“Best. Present. Ever.” He huffs out into the open air, groaning as his cockhead finally slips inside the perfect, tight cunt waiting for him. He hears Izuku’s pained whimper as the boy’s hymen breaks, feeling a new warm wetness coating his cock.
He glances down for just a moment, enough to see a flash of bright red as he pulls out slightly to work more of his giant length deeper. In, out, in, out, forcing more and more of his cock into Izuku's womb until his balls are nestled right against the vibrator still buzzing away on the omega’s clit.
“Fuck, that’s it.” Katsuki praises, “Tighten up, slut. Show me why I should keep you.” His resounding groan as the omega obeys the second the words leave his mouth, the already tight channel getting impossibly tighter as it squeezes the life out of his cock.
He wastes no time as he starts to thrust in and out of the heat-addled boy, relishing in the quiet sobs and pleads for more around the lollipop that he had shoved into the omega’s pretty mouth.
“A-Alpha?” Izuku slurs quietly, “Knot? Knot me? Been good,” He pleads with the unknown man, backing his thick ass up against Katsuki at the request, obviously not even aware that the alpha was raping him.
“Hold your fucking horses,” The blond scoffs at the tiny teen, using his alphan strength to pull the boy up by his viridian curls, forcing the boy’s back to arch almost unnaturally. It lets him drive his cock ever deeper into Izuku’s waiting pussy, the head of his cock pummeling the omega’s cervix without even trying.
That apparently drives Izuku insane, his pretty green eyes rolling up into the back of his head as the lollipop threatens to drop out of his mouth. He slowly gets louder and louder as Katsuki continues to thrust inside the teen, the new position allowing the alpha to get a perfect view of the bulge protruding from the boy’s stomach.
Katsuki clamps a hand right over Izuku’s tummy, rutting his cock harder into the omega’s pussy so he could rub his cock from the outside as well.
“Fuck, this feels amazing .” Katsuki praises, “Should have bought myself a fucktoy way before this, fuck. I could get myself a new little virgin every night, or maybe I’ll just keep you on my knot instead.” He threatens it without much thought as the beginnings of his knot start to pull on the entrance of the omega’s cunt.
Each retreat of his cock pulls small dribbles of slick and watery cum from the brainless bitch, the omega going practically boneless as Katsuki lets go of his hair. Watching as the previously-virgin teen fall to the bed with a small bounce.
Bakugou Katsuki doesn’t care though, not when his orgasm is so close at hand. Forcing his ever-growing knot into the boy over and over again, practically teetering on the edge of ecstasy as he chases the climax he desperately needs.
His alpha had been quiet since he got home, but the longer he went on with the mating of this vulnerable teen, the stronger it got. At first an annoying buzz of instincts that he could ignore, similar to the vibrator taped the omega’s clit. A distraction for sure, but something he could drown out.
But then it got louder , begging him to knot and mate the little middle schooler. Screaming at him that it wouldn’t allow him to knot until he finally gave in. With a growl, he obeys, alphan fangs on full display as he bites on the nape of Izuku’s neck.
Izuku feels the bond snap in place before Katsuki does, the omega giving a final, dry orgasm before completely passing out. But the alpha pushes on, tangy, sweet blood on his tastebuds as his giant knot finally locks in place
Katsuki gives out a groan of pleasure as he’s hit in the stomach with the force of his orgasm, releasing virile cum directly into the newly-presented teen.
The alpha is kind enough to wait for his knot to go down, thirty minutes straight of laying on top of the omega. Pressing soft kisses on the boy’s new mating mark, over the delicate freckles dotting Izuku’s face, and finally on the unconscious teen’s lips.
Even snaking his tongue inside to taste the sticky sweet candy taste left behind from the now-gone lollipop.
Katsuki whimpers to himself as his sensitive knot is finally released from its death-grip. A small trickle of cum and slick immediately spilling out of the boy’s abused cunt, and Katsuki can’t help but sigh as he surveys the mess.
First things first… he needs to tie down the omega in a comfortable enough position so Izuku can’t escape but he’s not in pain either.
Then, he’ll explain himself and Izuku’s new situation as the wife of a mob boss. Hopefully he won't struggle too much and accept his new role in stride. And if not... Bakugou can be very convincing.
"Happy Valentine's Day, Bakugou Izuku." He whispers to the sleeping boy. "Let's hope it stays happy."
