“Kacchan, have you seen my—“
“The cherry pop lipgloss is in the pink drawers.”
“But—“
“If you’re looking for your highlighter, you left it by the sink last night baby.”
“Shoot!” Izuku whines, hurrying over in a flutter to give a quick kiss on Katsuki’s cheek. “You’re the best, Kacchan! Thank you!”
“Yeah yeah, whatever.” Katsuki chuckles as he watches Izuku hurry off into their shared bathroom in a flurry of panicked movement, tripping over slightly on his own feet before stumbling as he rushes to get prepared. The blond shakes his head, fond, as he goes back to slipping on the red and black track jacket, checking his watch.
“You got ten minutes, Deku,” Katsuki calls, adjusting his sleeves before looking at the mirror to examine his own outfit. The high-cut maroon sneakers went with the black color block corduroy pants and retro jacket, his explosive blond hair contrasted against the dark colors nicely. “Tell me when you’re ready—“
The door to the bathroom busts open to reveal Izuku in all of his beautiful glory, beaming wide smile across his face as he sticks a pose: one leg up, hand throwing a peace sign by his eye as he cutely does a little twirl just for Kacchan.
Katsuki hums, eyes raking down his pretty omega’s body appreciatively, observing the velvet fabric, bubble gum tube top with Barbie scrawled on the chest and matching tight miniskirt that hugged that perfect ass. Izuku smiles up at him, cheeks bright pink as he shyly shifts those five inch heel clad feet, pedicure on point as always (Katsuki would know, he’s the one that fucking did them).
“Pretty boy,” Katsuki rumbles, and he watches Izuku giggle at the redden at the praise as if the alpha doesn’t shower him with them on the daily. “You ready to go to Mina’s, baby?”
Izuku nods, skipping towards him and taking his arm, attached to his side, the soft swells on his chest smooshing against Katsuki’s forearm in the process— and duh, the blond notices— he was his alpha.
“No bra today?“
“Nu-uh,” Izuku shakes his head absentmindedly, oblivious as always to the way Katsuki was staring at his boobs, blinking up confusedly when he realizes his boyfriend was rooted to the spot after trying to tug him to the front door. “Kacchan?”
“.. You’re lucky we’re about to be late,” Katsuki snorts, ruffling the omega who chirps with curiosity, attention easily curbed when the older man squeezes his ass and jingles his keys before slapping those fat cheeks forward and making the omega shriek . “Hurry up, idiot, or raccoon eyes ‘s gonna think that you seduced me into having a quickie before her party again.”
“Wh- I dont s-seduce you! It’s always Kacchan that touches me first and—“
“Whatever lets you sleep at night, babe.”
_____
Watching Izuku interacting with people was always a treat.
Contrary to popular belief, Katsuki wasn’t a jealous boyfriend— very far from it, actually. Hell, when he met Izuku during his freshman year of college, he didn’t even care about the dumbass rumors that were circulating the Uni: how Izuku sucked mad cock, the amount a bigger number than what he’s capable of what he can count to, if you listened in closely to the gossip.
Even if they were true, Katsuki couldn’t give less of a shit, because he was absolutely head over heels over the idiot at first sight when the boy walked into class fifteen minutes late, flustered and bowing profusely at the class and professor before sliding into the only open seat: right next to Katsuki.
And fuck Katsuki was weak. Izuku was pretty in all the right places, from the curve of his smile to his ass, the tight low jeans enough to reveal the hip hugging red thong, white sweetheart necked crop top dipping low and smelling like sweet summer breeze and mango popsicles on a hot day.
He was a talkative one too, waving excitedly at Katsuki as if they knew each other before pulling out those silly pens with poms at the end. The alpha watched in disbelief and utter awe as the omega kept drawing little.. sausages on his paper instead of taking notes, making him appalled and curious enough that he had to ask Izuku what the fuck he was drawing.
“They’re puppies!” Izuku chirruped, utterly pleased as he presents the deformed looking squiggles to the alpha, peeking behind his paper with pride. Katsuki didn’t have the heart to shatter his dreams, so he stiffly nodded, reigning in the urge to bust his ass laughing at the shitty hotdog dogs.
Katsuki slowly warmed up to him— how could he not? Izuku’s brightness had the orbital pull of the fucking Sun. At first the alpha liked how he was easy on the eyes, but that was usually it, and having a cute face never had him craving to possess or claim. The more he got to know Izuku, the more he realized how much of a genuine sweet person he was, painfully kind and an all-around angel. Unfortunately, getting to know Izuku more made him realize something: the omega was as smart as a goddamn ritz cracker box.
Present time, he observes as his oblivious boyfriend fawns over a flustered beta freshman, new on campus judging by the casual talk going around. The man was blond like him, a shitty black dye job of a lightning bolt stamped on whatever fucking shape his side-bang was in, red solo cup in trembling hands as Izuku practically squishes them both together on the couch.
Kirishima, one of Katsuki’s few acquaintances, casts a friendly wave at him which he returns with a short nod before bursting out laughing at the way Izuku threw his arms around the blond and startling the beta in the process— who splashed himself with the beer he was holding.
Izuku’s lips open in a gasp, and he flutters around in concern, unable to pick up the way the beta was about to have a stroke when his hands end up on the stain on his stomach— and that’s when Katsuki chuckles and decides to step in unless the dude was going to die from Izuku’s dumbass.
He easily pushes through the crowd of college students grinding on each other under flashing pink lights, crushing his empty solo cup and tossing it in a random bin in the corner, ignoring the betas and omegas making googly eyes at him. Katsuki was only focused on Izuku, after all.
“Oi,” he grunts, and Izuku looks up with sparkly doe eyes before he brightens at the sight of his boyfriend.
“Kacchan!” He chirps, and Katsuki widely smirks at the way the color in the beta’s face fucking drains at the sight of the massive man right in front of them, especially when the omega kissed his cheek, tugging him to sit next to him before eagerly sitting on his lap. “Denki, this is Kacchan, my alpha!”
The beta is left reeling, and a little green, considering the omega was all up on him seconds ago.
“You new?” Katsuki decides to hum casually, letting Izuku wiggle a bit to get comfy, his own arm wrapping around that waist, his omega clearly tinier in comparison. Denki watches on, sweat dropping and looking afraid.
“I— I didn’t know he was with you, man—“
“Bakubro!” Kirishima claps Katsuki’s shoulder, rambunctious laugh making Izuku rattle a bit in his lap, before scrambling up to hug Kirishima excitedly next.
The redhead alpha remains unbothered, hugging the omega back with a bit of pink on his cheeks before snorting amusedly. He was a third year like them and was familiar enough with Katsuki to know he’s fucking with the beta. “Lay off the new kid, yeah?” Said new kid cast him a grateful, twinkling grimace of a smile, and he gives a supportive thumbs up before ruffling Izuku’s hair in the lieu of greeting.
“Yeah yeah,” Katsuki grins and it’s all teeth and sharp. Izuku just tilts his head, confused at the interactions, feeling like he was missing something with the way Kaminari looked like a deflated balloon and Kacchan was cockier than usual. But still, he doesn’t worry too much, opting to take the much better option of being content arm-candy as his alpha talked to his friends. “It’s funny watchin’ them freak.”
“Sadist.” The redhead jokingly grimaces, before he smiles kindly to the beta, gesturing to Katsuki. “This guy’s Bakugou Katsuki, and Midobro’s his omega. Don’t sweat about messing with Izuku earlier, man! He’s just a.. real touchy one.”
Izuku waves at Denki with a wide grin, eyes shiny and bright. Meanwhile, his alpha nips at his cheek, a possessive claim that had the omega squeaking and scoldingly hitting his chest.
“I’m Kaminari Denki, by the way!” The beta pipes up now that he’s got assurance that a possessive alpha wasn’t gonna tear his throat out in the middle of a college party. Izuku beams, looking up at Katsuki who shrugs uncaringly and continues sipping out of his red solo cup and drawing little teasing circles on Izuku’s waist.
“Whatever, dunce face.” He drawls, gesturing vaguely in the direction where the mini-bar was located at, with Sero already acting like a fake bartender after raccoon eyes probably promised the little stoner some weed in exchange for his expertise around drinks. “Go grab a drink ‘n loosen up. Not gonna get any dick if you look like you’re about to keel over.”
“I-I’m not—!”
“Fine. Not gonna get any pussy if you look like you’re about to keel over.” The alpha raises a brow, unperturbed at the spluttering, as if daring the beta to deny it after he was drooling over Izuku’s pretty ass two seconds ago (not that he blames him. Still, Deku was his).
“Come on man,” Kirishima chuckles at the freshie’s spluttering, patting a heavy but helpful hand on Denki’s shoulder. “Let’s go grab some shit to drink and come back yeah? Don’t sweat it, it’s Bakubro’s way of telling you to relax.”
Izuku waves them off giddily when they dip through the crowd, before going back to his Kacchan.
“I’m gonna go find Ashido!” He puffs his cheeks, determined and eyes sparkling— probably because the shitty pink-haired alpha loved spoiling Izuku so much. Last time Katsuki let them be alone together at the mall, Izuku came home with an armful of shopping bags stuffed to the brim with All Might shit.
“Don’t get lost, baby.” Katsuki reminds him, only half joking as the omega salutes him and the alpha sends him off with a forehead kiss.
In the corner of his eye, he sees Kirishima approach as his head follows Izuku’s trail, straightening and giving a nod in Katsuki’s direction as he slowly follows behind the ditzy omega.
Better safe than sorry when in a college party, if Katsuki were being honest.
It won’t be the first time someone would try to take advantage of Izuku’s ditziness. It happened only once when Katsuki was present— it was when he was a fairly new addition to the omega’s life having brushed shoulders when their two friend groups somehow linked together, shared occasional smiles and nods of acknowledgment before.
A different college party, a wilder crowd. A shit ton of older people from the other branches, filthy rich and mingling in a mansion. With a pool and hot tub: the owner was disgustingly wealthy, inviting everybody on campus including Katsuki and Izuku.
Katsuki went after Izuku rambled about how it would be a good bonding experience or whatever, so the blond threw on a casual tight black shirt and cargo pants, unwilling to swim but also unwilling to turn down being with Izuku (even if it meant he had to share with multiple people, but whatever).
What he didn’t account for was the omega turning up in an already skimpy, loose transparent sundress with a goddamn micro-kini underneath, absolutely oblivious to the stares he received when he arrived at the party and bound over to Katsuki with excitement comparable to a puppy. And sure, the alpha’s eyes absolutely wandered to those soft B-cup tits and perfect fat ass— but he did not try to cop a feel, even when the omega launched himself at Katsuki with his enthusiasm.
He did however, have to discreetly hide his erection in his pants as Izuku sat on his lap yapping about how elated he was that Kacchan showed up, boobs all up the blond’s face and bubble butt practically grinding on his dick in the middle of the damn party.
“Midor— Izuku, why don’t you go swim ‘n shit?” He remembers asking, considering it was a pool party. He also remembers the way Izuku pouts, doe eyes glimmering in the neon pink lights coming from the LEDs stuck around the room to have a more atmospheric feel.
“But I like talking to you,” he nuzzled closer, contorting a way to fill the little gap between them and giving the alpha a fucking heart attack. “Can you come with?”
“Fine.” Katsuki groused sitting up, pretending as if he didn’t agree too fucking quickly. “I’ll only sit by the pool, don’t wanna be around idiots who can’t control their drinking. Not risking getting thrown up on at the pool.”
“That’s gross, Kacchan!”
The pool was fun, and it was priceless seeing other people’s jaws drop when Izuku shrugged off the sundress and tossed it to Katsuki with a giggle before splashing in the pool; much to another chick’s gasps of belligerence after trying all night not to get chlorine in her hair.
The omega was resolutely drifting around him the whole time, shucking off the occasional hopeful alpha— even omega— that approached him with an oblivious little smile.
Deep inside, Katsuki was thankful for the company.
They conversed and Katsuki found Izuku absolutely hilarious even if the omega didn’t try to be. He was stupidly optimistic— not in the fake way it ground on his nerves either. He was genuine to the core, determined to graduate to prove himself. Their conversation was rudely interrupted by an omega sauntering closer to Izuku, and her approaching figure was first noticed by Katsuki— trailing off when he raises his brow at the mischievous smile on her lips.
Izuku who was unfortunately facing away, looked up curiously at Katsuki, wondering why his friend stopped talking: until of course, he feels hands on his hips, digging in and making him gasp and whip around.
“O-Oh!” He squeaks as the omega leans close, and suddenly both of Katsuki’s brows hit his hairline when the brunette omega gets all up in his face, damp grubby hands fucking feeling him—
“You’re Midoriya, right?!” She’d chirped, lips practically brushing against a freckled shoulder and Katsuki crushes the beer can in his hands, “I’m sooo stoked you came!”
“R-Really? Oh, I’m glad!” He rambled, not quite picking up the fact that she was too close and too touchy, “What’s your name again—?“
“Jun! I see you in my classes sometimes! Your outfits are sooo cute!”
A hand slipped down underwater, to Izuku’s ass— and her blood red lips were too goddamn close—
“Oi,” Katsuki snaps, “Get your damn paws off of him.”
“That your boyfriend?”
“Kacchan? Oh, he’s my—!”
“I’m his alpha, dipshit.”
Izuku’s eyes widen, and Katsuki ignores the way he felt his own cheeks get hot as he bares his large canines at the piece of shit, “Scram before I drag you out the damn water for groping my omega.”
The other omega rolls her eyes, pouting like a petulant child, but releases Izuku from her claws all the same. “ You’re no fun, ” she drawled.
Izuku blinks confusedly at her retreating figure, but shrugs it off to happily splash around in the water.
From then on, Katsuki had acted like a guard dog for Izuku. Always on his ass, right behind him like a shadow. Others see it as annoying mostly since they’re too afraid to be a victim of a mauling when you get too close to ‘his’ omega, but Izuku didn’t really mind— in fact, he relished the attention and thought of it as spending time with his best friend.
They grew closer in the span of months, and after that, Katsuki had popped the question in the middle of a studying session.
“Wanna be my boyfriend, nerd?”
It was so sudden, and the blond didn’t even mean to blurt it out. It’s just Izuku was so fucking cute, brows furrowed, pretty lips pouty as he struggles with whatever calculus problem he had on his paper— trying his best despite the fact that he claimed to be not smart or whatever shit he spouted.
Katsuki fell for him so damn hard it was sickening. He’s pretty sure the omega could get up and slam that heavy math textbook he had into his teeth and make him wear dentures for the rest of his life and he’d still want to date the little shit.
Izuku’s eyes just widened and his lips curved into an ‘o’— before squealing excitedly and launching himself at Katsuki, homework forgotten as he jumped the blonds bones for the rest of the night.
After all that came the obnoxious PDA— but really, who’s gonna bitch? Izuku’s daddy funds UA, and Katsuki hard carries their whole college on his GPA and football career alone .
Present time, Katsuki was having the time of his fucking life beating the shit out of some freshies in beer pong, cackling when Sero had to haul some cocky little bitch out the door because he was seconds away from throwing his guts up on Mina’s carpet. The rest of the idiots weren’t dumb enough to challenge him, clapping him on the back and hooting and hollering obnoxiously because of his win.
He feels a hand on his shoulder, and he cranes his neck to the right to see a familiar pink-haired alpha.
Speak of the fucking devil.
“How’s the reigning champion!?” She teases over the loud blast of bass, smiling widely and Katsuki returns it with a smaller quirk of his lips— his own version of a smile, and it was genuine all the same. She daps him up in greeting, jerking her head into the crowd of college student zombies and making the beige horn headband on her curly hair flop around. “Your omega’s at the bar, by the way.” She licks her lips, feral grin on her face, “Sero’s setting him up for body shots.”
Katsuki raises a brow, and promptly ditches the crowd around the pingpong table, making Mina roar in laughter as she follows after the tunnel visioned alpha.
“Better hurry up before I do it.” Mina croons, and Katsuki playfully snaps at her as he half-jogs to the bar, feeling the familiar pool of warmth on his dick at the thought of his Deku squirming and giggling obliviously as Sero smears the salt between his tits and slipping a wedge of like in his mouth.
They arrive in the main living room, and Katsuki steps over some shitfaced beta on the floor to greet his omega— currently perched on the island counter, surrounded by the usual college suckers trying to desperately impress Izuku.
“Yo, Bakugou.” Sero grins lazily, eyes droopy as always. Surprisingly, he didn’t smell like weed, but Katsuki suspects that he’s high on something else anyways with the way he slothfully moves his hand in a lame greeting. “Got your shots ready, man.” He gestures to the tequila shots lined up on the counter by Izuku’s ass.
Izuku himself flutters his lashes, before humming as Sero slides a slice of lime between his lips.
Mina whips out her phone, as do the people in the crowd. They’re jeering and whistling, a loud crescendo of idiots who desperately wanna see some action.
There were two types of people in UA University— those who either wanted to be Izuku or Katsuki— or those who wanted to be with them.
“Hi Kacchan,” Izuku whispers, eyes sparkling under the purple LED lights as he giggles like a preschooler with a little secret. Katsuki makes a home between his thighs, pressing up against the cool counter.
The alpha croons back, quiet as if they were the only ones in the room, “Hey, baby.” He licks his large canines, using his right hand to squeeze the first shot between his thumb and middle and pointer finger. “Let’s give them a show yeah?”
Katsuki curls his tongue between the soft mounds of his tits shamelessly, earning a shudder as he throws his head back to the roars of disbelief and shaky excitement, before he surges forward to capture Izuku’s mouth with his. He doesn’t bother to take the lime out- instead, he squeezes it between their lips in a brutal kiss, letting the sour juices drip between them.
Izuku whines, cheeks red as his boyfriend gropes him in front of crowds of people. He feels himself slick when Katsuki sucks on his tongue, back arched as they practically fuck with clothes on.
“Pinky,” Katsuki growls between lewd squelches of his tongue down Deku’s throat, not bothering to look at the other alpha. “Give me— Deku, ngh— your fuckin’ guest room for tonight, yeah?”
The smell of omegan arousal was making the crowd rowdy— and if it were up to Katsuki, he’d fuck Izuku right then and there. Still, he had some semblance of thought— and while they were given special exceptions in UA— they wouldn’t be lenient towards a public sex tape between two students being leaked.
“You gonna have fun blondie?” She chuckles, but shows a supportive thumbs to give them the go-ahead.
Katsuki kicks off the counter, both hands firmly on his baby’s ass cheeks, squeezing as the little green-haired vamp nibbling greedily at his scent gland. The crowd forms parts like they were the Red Sea and he was Moses, and the high from the power trip is really getting to his head.
“I’m gonna knot my pretty bitch on those fuckin’ sheets.”
-
Izuku was a whiny mess as Katsuki held onto his thighs tight, one leg over his shoulder with his omega’s upper half was on the bed while the lower hung off of the edge, trusting Katsuki’s strength.
His ankle-high strappy pink heels’ buckles were digging into the meat between his shoulder and neck— but did Katsuki give a fuck?
The answer when he flipped that tiny piss poor excuse of a mini skirt that looked like a string of dental floss up was a resounding no.
“Cute panties.” Katsuki teases, nuzzling lovingly into the G-string, lashes fluttering as hell inhales the pure musk of Izuku. His omega’s thighs close on instinct, squeezing his head between pillowy heaven as his cock twitches in his boxers.
“Kacchan,” and god he sounded so wrecked already, “p-please..”
The alpha hums, tugging the string of underwear aside. “I got you, sweetheart.”
He frames that pretty cunt with either hand placed on his inner thighs, thumbs digging into his puckered asshole, drenched from Izuku’s pussy already leaking a river of slick. The omega mewls at being exposed, pussy clenching and unclenching as another glob of his juices leak out and trail down onto the sheets.
Katsuki doesn’t waste time— he nips at that tiny, throbbing clit before kissing all over Izuku’s labia, sucking his lower lips lewdly into his mouth as he drank up. Heat and lust was making his mind swirl, so he practically face plants into that cunt to fuck his tongue into that pink hole.
Meanwhile, Izuku was crying . His face was hot and red, and half of his top was folded over so his nipples were perky from the cold air and arousal as his boyfriend eats him out like a starved beast. He hiccups a sob when that wicked tongue slips down to dip into his asshole, swirling, nibbling at his rim as the slick from his pussy aided the slide.
Kacchan gave a hard suck to his rim, before placing a little forlorn goodbye kiss on it. As much as he loved anal, it wasn’t his focus right now. He wants to knot his omega and pop a fat knot in his cunt, preferably before the clock hits five AM.
“ Ahn— mm— Kacchan, Kacchan, ah, ah—!”
With spit-slick lips the alpha mouths his way up, kissing that little tummy before dipping his tongue into Izuku’s bell button, earning a little squeak that melts into a mewl. He surges up like a man on a mission, hands rubbing up and down his omega’s sides when he comes face to face with those pretty tits.
Izuku’s got the body of a goddamn slut, with wide child-bearing hips and a tight waist, small pooch on his tummy, perfect for accepting Katsuki’s seed. One of these days the blond’s going to fuck a baby into him— and he can’t fucking wait.
“Pretty boy,” Katsuki cooes, relishing the blush that spreads down to his omega’s chest, the fucked out look on his face with wide unfocused doe eyes and lips curved into a cute ‘o’. Izuku always got like this when he got praised, or touched, or fucked. The dumb little thing was oblivious to his own penchant for praise, getting wet when anyone coddles him and being all whiny and confused after.
His professor had given him a B minus on a quiz, the highest grade he’s ever gotten, even ruffling Izuku’s hair in a prideful friendly way? A squirt of slick.
Ochako and Iida, fellow students who cheered him on before a test and fawned over him for getting at least half of the calculus questions right? Drenched.
Kacchan praising him with a simple good boy or a kiss to his cheek? Panties soaked .
It was fun to see Izuku squirm, so confused why he’s turned on.
Katsuki sucked his right tit into his hot mouth before popping off to kiss at those puffy buds, and Izuku shuddered at the cold air that hits them, panting with a hummingbird chest. He was helpless , sloppy and uncoordinated when he got so horny that it took over the rest of his brain cells and turned him into a mindless slut.
But it’s okay, because Kacchan was here.
“Good fucking omega,” Katsuki growls, cupping the back of his thighs before pushing. This way, Izuku’s legs are shoved to his sides, knees up to his ears in an impressive show of flexibility. Izuku squeals, babbling shamefully as his asshole and pussy were on full display to his alpha, pink and soaked with slick. He clenched around a nonexistent cock, clitty needily twitching from the lack of contact.
Katsuki yanks off that G-string and, like the complete degenerate he was, sucked on the soaked fabric before he stuffs it into his back pocket. It’s not like Izuku doesn’t know about his tendencies to be a little too into his— well, everything — so he doesn’t question it when Katsuki swipes a couple of his used panties here and there.
“Keep your eyes on me.”
Izuku doesn’t even need to be told that.
His alpha pushes down his pants, hooking the fabric below his balls. Izuku’s undress juxtaposed Katsuki, who was still fully clothed aside from his cock slipped out his boxers— and shit, what a cock it was.
Kacchan’s dick was wide and girthy, so heavy that it hung between his legs. It was an angry red, dark compared to the rest of him with the rip fat and leaking so much that Izuku wanted to suck him off stat .
But it’s not what alpha wants, so he obediently purses his lips but lets little needy omegan cries slip out, trying to sneakily entice Kacchan’s alpha into responding with the instinct to comfort and keep him safe. Katsuki holds himself at the base, wetly slaps his cock down on that messy cunt, enjoying the tiny hot pussy that was practically mouthing against his dick and the primal little chitters that Izuku emits.
The alpha leans down, so Izuku’s forced to make eye contact with him, staring into those crybaby pools of emerald.
“I’m going to fuck you pregnant, pump you full of pups.” A lick to his ear, a pinch on his nipple making him clench down. “And I’ll make you my perfect little housewife.”
A promise. A vow.
Izuku’s whole body quakes .
Katsuki’s eyes were pinning him under his gaze, and the omega was hyper aware of the hot breath against his neck, their bodies slotted together, every twitch and jump of Katsuki’s muscles against him—
Izuku’s eyes roll back when the alpha finally sinks into his cunt.
“K— Kah—!”
“That’s my baby. Moan louder, okay?” Katsuki leans down lower, and he finally snaps his hips forward, and Izuku can hear the sharp smirk. “Makes those limpdicks listening on the other side of the door wish they were me.”
The alpha pulls his hips back, groaning when he feels those tight wet walls suckle on his cock, begging for him to stay inside— before he slams back in with a lewd squelch.
“ Kawcchan ,” Izuku slurs, voice wrecked with tears, “Y-You’re gonna break my pussy—“
“ Good.”
Izuku holds on for dear life as his cunt was pummeled, the fat head of Kacchan’s cock hitting his cervix repeatedly. The bed was squeaking along with the omega’s sobs and the alpha’s deep grunts, and Katsuki’s pride sang with the way Izuku thrashed from getting stimulated.
The poor omega couldn’t do anything from the brutal onslaught of pleasure and the cock kissing
his cervix.
Meanwhile, Katsuki dips down and catches one of those soft bouncy tits in his mouth, moans muffled by the flesh as he keeps his eyes wide open to tattoo the sight of Izuku’s face on his eyelids; eyes were crossed, pink little tongue out as slight drool as he’s fucked stupid, just how Katsuki loves it.
The alpha’s fat balls slapped against Izuku’s taint, twitching with the cum that was begging to fill his bitch’s pussy.
More.
Katsuki’s rhythm stutters as he slowed into purposeful, deep grinding, languidly dragging his cock along those velvet walls. He didn’t even need to angle his hips to hit Izuku’s g-spot with his dick so fucking big it puts pressure on everything .
Izuku gasps for breath at the short break, responding in his own broken chittering when Katsuki chuffs in the back of his throat as praise for him being so obedient. The omega feels hot shame and arousal when his alpha stares at the spot where they’re connected so intimately, feeling even more embarrassed at the way a squirt of slick floods Kacchan’s joggers and the sheets under them.
He couldn’t think— his head was so cloudy, it was as if someone stuffed cotton in his brain. For some reason the thought makes Izuku giggle almost drunkenly.
Katsuki raises a questioning brow before a fond smile tugs on his lips.
“What ya laughing at, Deku?”
Izuku squirms, cheeks baby pink as he shyly hides behind his hands. “‘m soo full, Kacchan,” he whispers, blinking dumbly, “Feels good..”
Katsuki hums thoughtfully, keeping up the slow pace of pumping his cock in and out. Fucked stupid Izuku usually babbled like this when he felt good, running his cute little motormouth about his little thoughts. It was infuriatingly adorable, and the knowledge that Katsuki could literally make him go brainless for his dick made him twitch inside his boyfriend.
“You love it when your alpha makes you feel good right?”
“M-Mhm!” Izuku’s cry is pitched and whiny when Katsuki’s calloused thumb strums his slimy clit, rubbing the little nub before lightly tapping— making Izuku squeeze down on his cock as the little jolts of pleasure make his hips jump.
The omega’s eyes snap wide open, and the only warning Katsuki gets his his squeal of pleasure before that peachy count bares down on him and gushes, the squirt drenching his cock and pants to the point that, if they weren’t unsalvageable before, they definitely are now.
The blond doesn’t waste time of course. He holds Izuku down into the deepest mating press he could muster, his omega’s overstimulated, desperate croons and frantic chirps for mercy ignored as his lizard brain fucking takes over.
Pups.
Katsuki snarls at the premise.
“K-Kacchan, I cant—!”
Izuku sobs when he slams his hips forward with renewed vigor, unstoppable, helplessly jostling as he was used like an onahole.
His— his pussy aches so bad! The pain and pleasure were melding together, blurring his vision as he clawed the sheets. He can’t believe his own cunt was making those sounds—
“That’s my good slut,” he hears, and Izuku squirms and whines listlessly,
“ Nooo ,” a hiccup, “ not a s-slut—!”
“Yeah?” Katsuki goads, breathless as he watches his boyfriend whine and gasp every time his cock plowed through him. “What do you call this then, baby? You spread your legs pretty fuckin’ easy.”
He was teasing, of course, but Izuku didn’t know that in this state. Instead, the omega tears up, whimpering as he tries desperately to prove it’s only Kacchan, only ever will be him—!
Katsuki licks that freckled cheek, shuddering at the salty taste of tears as his balls slap against that pink puckered asshole. “I could slut you out if I wanted to. Everyone wants to hit, did you know that?” He laughs, deep and cruel, “God, Deku, do you even see the way our damn friends look at you!?”
Lingering looks, lewd jokes. Izuku was just so painfully pretty it made Katsuki want to hurt.
“But it’s fine.”
Izuku’s eyes roll back pitifully when he opens his maw around his throat, alphan fangs dripping with saliva as he breathes in his scent.
“Only I can make you like this.”
The omega’s cunt squeezes around his length again, babbling mindlessly as his spine curves sinfully and he creams and squirts on Katsuki’s cock.
Katsuki growls, and tears his mouth away from that neck to avoid fucking marking his mate right there and then only to sink his teeth into the meaty junction of his neck and his shoulder. His thrusts speed up when he feels his knot inflating, and he fucks it forcefully into that chubby little pussy before finally it locks.
“ Fuuuck..“
The alpha slumps, groaning when he cums deep into Izuku’s pussy, feeling it suction and milk him so goddamn good. Katsuki rolls his hips as Izuku whimpers all weak, and the blond pulls away a bit to see his omega’s expression.
Izuku was thoroughly fucked out, jaw slack as he mumbles and chitters without a care in the world. His eyes were dazed, unseeing, face completely flushed. At that, Katsuki smirks while huffing under his breath as he fondly rubs Izuku’s freckled cheeks.
He waits for Izuku to come to the surface, helping Izuku ride out his high with gentle kisses on his sternum to his neck, licking lightly on his those pink nipples as he sucks hickeys onto that bare neck. Meanwhile the omega was snuffling and responding to his croons with his own mewls, and soon enough, Katsuki sees the way he comes back to life.
“Hey baby.”
“H-Hi Kacchan.” He giggles, light pink as Katsuki hunches down to kiss his forehead, then his nose, then his lips, chuckling when Izuku cooes under his tender ministrations. “My pussy’s sore.”
A snort escapes Katsuki at the casual, airy remark. Leave it to Izuku’s airheadedness to make the omega incredibly blunt. “I’ll carry you to our dorms.”
“Mm..” a pause. Then he whines, “Oh shoot, where’d my panties go?”
“Dunno.” Katsuki smirks halfway into their kissing, pecking those bruised red lips one last time and pretending as if a sliver of hot pink fabric wasn’t leaking out of his pockets. “Wanna get the hell outta here? Don’t want anyone seeing you like this right now.” His red eyes rake over that tiny little chub at his once flat tummy, preening at the thought that his cum was stuffed right in there. “Or smellin’ you, really.”
“I feel like jelly..” Izuku pouts, the shell of his ears red as he nuzzles into the pillows next to him. He was the picture of when a sex-satiated omega looked like, all pretty and glowing as he cheekily peers over the sheets. “You said you’d carry me right..?”
Katsuki rolls his eyes.
In the the end, he’d ended up texting Mina to bring up some wipes and scent patches, which the alpha gleefully supplied with a quick throw through a crack in the door. Katsuki did his best wiping his omega down after he’d pulled out (and snapped a picture for his spank bank, much to Izuku’s whining) before cleaning off his flaccid cock.
They had to go home with Katsuki’s jacket tied around his waist because of his ‘missing panties’, and his omega was blushing and stuttering the whole way out the house because of the constant staring they got from everyone. Mina was chortling about how certain people had their ears pressed to the door, just as Katsuki had predicted, and half of them had to go home while guiltily adjusting their pants with bright red and dazed faces.
Most of the regular party go-ers knew about the pair’s insatiable libido and were mostly used to the inescapable fact that nine times out of ten, Katsuki and Izuku will be banging somewhere in a party. It was just a matter of when.
It’s why Mina had the keys to her spare bedrooms ready. And how Kirishima was used to it having been a victim of the constant PDA between the couple, but he admits that he still gets pink in the face when he remembers those sweet muffled moans and squeaks when in the presence of Izuku (Katsuki’s well-aware of his friends’ constant hard-ons for his omega and holds it above their heads constantly to taunt them).

“Kacchan, daddy’s calling.” Izuku mumbles sleepily once they’re settled in their shared dorm, making the alpha’s eyes widen when the omega shoved his pink phone into his hands, cutesy charms clinking together as the display read Daddy! With various flower emojis spammed next to his name. “Answer for me please, ‘m sleepy..”
“Oi, Deku, don’t you dare—“
Katsuki’s mouth drops open when the omega seemed to instantly conk out, mouth open and all as he sleeps splayed like a starfish, party clothes still on him.
“ Fuck.”
The blond gulps, lips pressed into a thin line as he answers the phone.
“Izuku baby, your old man just wanted to check on you!”
“Izuku’s not here, Mr. Midoriya,” Katsuki awkwardly coughs out, ignoring the way the line goes deathly silent until a single gruff “Oh.” Rings through, a harsh contrast to the almost-baby talk earlier. “He’s actually asleep.”
“Mm.” Unnerving as always, Midoriya Hisashi, Izuku’s dad hums. It always made Katsuki painfully anxious because the man was fucking unreadable— which in hindsight, should’ve been expected since he was the CEO of MAIDO-tech (which Izuku had vaguely explained as a weapon company which caused a lot of heads to turn when he threw it out there so casually).
“Well I do hope that you’re both taking care of yourselves.” The older alpha pauses, as if contemplating. “And that you’re taking care of Izuku. I know how my son can be, so I’m.. glad that he has someone to look out for him.”
The closest thing to a compliment Katsuki could get from him, and honestly? He felt a weird warmth in his chest that he immediately pushed down, clenching the phone a little tighter than normal.
His omega’s sire trusts him.
The pair of men may not have the steadiest relationship, but there was an air of unspoken respect between them as being the most important alphas in Izuku’s life. Hisashi was a little overbearing but who could blame him? Certainly not Katsuki. And sure, he grilled the shit out of Katsuki and did some background checks when they first met (which the blond found.. less than thrilling), but he was Izuku’s dad and damn it, the last thing the blond wanted to do was bitch about his future father-in-law.
So Katsuki brushes the hair out of Izuku’s eyes, watching his cute omega whine and nuzzle into his palm— and he sighs and answers Hisashi with utmost certainty,
“Izuku’s going to be my mate. I’ve got him, Hisashi.” He leans down to kiss that freckled cheek, a small gesture as if to seal his promise, “I’ve always got him.”

“Kacchan.”
“Mm?”
Izuku fiddles with his thumbs, a small pout on his lips and a crease between his brows. Katsuki’s hand automatically lifts up as he placed a thumb on that crease to playfully massage it down, earning a little giggle.
“What’s got into your pretty lil head?” Katsuki shuts his stats book, pushing it away as he favors letting Izuku snuggle into him more on his lap.
“I’m just really glad Kacchan likes me.” He sighs all pleased and basking in his alpha’s smell, “You’re just really smart ‘n stuff, and you help me with school.”
The alpha chuckles, kissing down that neck and earning soft whines. “Yeah?” He pinches his cheek, admiring the squishy baby face his boyfriend’s still got going on. “And you prevent me from losing my fuckin’ mind on the daily.”
“Really?”
“Mhm. I mean shit, Deku, I didn’t know the damn word relax until you.”
Izuku looked really relieved at that, shoulders sagging as he finally kissed back. They make out for a few minutes after that, with the little omega on his lap and sharing each other’s warmth before Izuku finally pulls away with spit-slick lips and a dazed look.
Fucking pretty.
“Kacchan?”
His hand crawls up those thick thighs, breathing shallow as he waits with baited breath. “Yeah baby?”
His omega bats his lashes demurely, before tilting his head. Katsuki didn’t even notice leaning in until Izuku stops him and suddenly, he was all fidgety and shy again.
Katsuki raises a brow, slightly concerned. “What?”
“I’m.. um.. about the calculus homework…”
“Oh my god.”
Izuku squirms and whines, embarrassed since he probably just killed the mood. “Sorry Kacchan—!”
“It’s fine, Deku.” Katsuki chuckles with amusement, already leaning forward to grasp the solid textbook waiting for him at the edge of his bed. “After this, you can sit on my dick all you want, yeah? Gotta get those damn grades up first.”
“Thank you, Kacchan! Love you!”
“Love you too, shitty nerd. Anyways, open up your notebook to..”
