Bkdk a/b/o - age difference (44/19) 😈 ph!bkg/ql!dk

Katsuki can’t help it. He can’t help the way his eyes wander when Izuku, his daughter’s best friend, comes around.

Ochako is his pride and joy, studying engineering even after finishing up her time at UA.

At college, she met Izuku. Sweet, quirkless Izuku, with the tightest little ass Katsuki has ever had the pleasure of laying eyes on. A lean, short little body he’d be able to manhandle, bend over -

“Thank you for making a delicious dinner, Mr. Bakugou,” Izuku interrupts with a smile, wiping his mouth as he stands to do the dishes.

He grabs Katsuki’s empty plate, swaying his hips as he walks away, and there’s no way the little minx doesn’t know what he’s doing, right?

“Thanks for letting us stay here for the week, dad,” Ochako says, pecking him on the cheek, so blissfully unaware of the way his eyes are glued on her best friend’s ass.

The two of them are staying with him for spring break, and Katsuki’s not sure how he’ll survive it.

-

“Oh!” Izuku squeaks, crossing his arms around the towel he’s wrapped up in. “I-I’m sorry, I didn’t know you were home, Mr. Bakugou!”

“Call me Katsuki, kid,” Katsuki says gruffly, beating down the blush threatening to bloom on his face to match Izuku’s.

“K-Katsuki,” Izuku says, dipping his head respectfully, and Katsuki kind of hates how it reminds him of how much older he is than Izuku. How wrong it is for him to be attracted to the omega. “Sorry, sir, I’ve just been your biggest fan since I was a pup!”

Since he was a pup. Jesus Christ.

“Yeah?” Katsuki asks instead of actually slamming his own head into the wall. “Dynamight fanboy, huh?”

“You’re the number one hero,” Izuku says matter-of-factly. “Who /isn’t/ your fan?!”

“You’d be surprised,” Katsuki chuckles. “Lots of people aren’t really into the whole shitty personality I got going on.”

“But you’re so cool!” Izuku immediately defends, and Katsuki suddenly remembers that there’s a half naked nineteen year old in the room.

“Go get dressed,” Katsuki coughs. “Then we can talk more, if you want.”

“Of course I want to!” Izuku practically shouts. “B-but, um, I totally forgot to pack clothes, so I have to borrow some of Ochako’s….”

Katsuki shrugs nonchalantly, but he internally panics, because the image of Izuku in leggings and a crop top suddenly flash through his mind, and his dick definitely didn’t get the memo of “he’s way too fucking young.”

“You can borrow some of mine,” the blond offers, and Izuku beams.

The small omega follows him back to his room like a little duck, eyes wide and innocent as he watches Katsuki pull his smallest pair of sweats and an old shirt out of his drawers.

Izuku shuffles on his feet awkwardly, suddenly looking shy.

“What’s wrong?” Katsuki asks. “Too big for you?”

“Do you have any underwear?” Izuku asks quietly. “N-nevermind, I can borrow some of Ochako’s!”

Katsuki raises an eyebrow. “I’ll wash the pants when you’re done, nerd. Don’t get your panties in a twist.”

“I don’t wanna ruin them, sir,” Izuku says, chewing his bottom lip cutely. “I, um…”

“What?” Katsuki asks, suddenly feeling like he’s on a thin rope.

“I get… really wet,” Izuku blurts out. “Uhm, for no reason.”

Katsuki’s brain goes offline for a few seconds, and he’s pretty sure he stands there staring into space like a dumbass.

“Come again?” The blond says.

“And, um, it’s gotten really bad since I got here,” Izuku continues, so unaware (?), shuffling his thighs together as if to prove a point.

Katsuki’s mouth drops open, that addicting, soft, vanilla scent wafting from Izuku in waves, sweet and clean after his shower.

“I think…” Izuku trails off, looking up at Katsuki with those fucking doe eyes. “I think it’s because of you, sir.”

Katsuki wipes his hand over his mouth, backing away slowly, because he needs to leave before he does something dumb.

“Get dressed,” Katsuki says, voice low, gripping the door handle behind him, his eyes never leaving Izuku.

“I wanted to show you something first,” Izuku says, toying with the top of his towel with a finger. “Ochako won’t be back for an hour…”

“Izuku,” Katsuki warns, but he makes no move to open the door.

At that, Izuku gives him a smile and lets the towel drop, revealing the body that’s somehow even better than Katsuki pictured, his hands crossing over his chubby little pussy shyly.

His nipples pebble in the cool air conditioning, his cheeks red and soft.

Katsuki immediately feels his cock give an interested throb, hardening up as his unblinking eyes roam over Izuku’s young, smooth body.

He curses his inner alpha, already screaming at him to fuck, breed, impregnate -

“Do I look good?” Izuku asks shyly, sounding nervous, and Katsuki groans, because again, nine-fucking-teen.

“Move your fucking hands,” is all Katsuki says, voice firm, and his lips twitch sadistically when the omega immediately obeys.

Izuku’s pussy is a thing of wet dreams, shaved and fat and glistening with slick, and Katsuki knows his cock is definitely showing through his joggers now, angry and hard and pressed against the material desperately.

Izuku’s eyes are glued on it, letting out a pitiful little whine as he turns around and plants his hands on Katsuki’s king sized bed, hands gripping the plush sheets as he arches his back out and presents himself.

That perfect, perfect pussy splayed open beneath a glorious, freckled ass, the front of his thick thighs pressed against the side of the bed as he slides down further.

Katsuki loses it, slamming himself onto his knees behind someone less than half his age, burying his face right into that wet pussy hungrily.

TBC bc of course I made it too long to be a one shot 🤣 two shot it is??

Cw: degradation, mouth-spitting

Katsuki drags his lips back and forth across Izuku’s slicked pussy lips, feeling that little body tremble against him.

“S-sir!” The omega nearly screams, slamming his hand over his mouth to stifle himself.

Katsuki sticks his tongue out and runs the wet muscle from Izuku’s clit back to his pussy hole, wrenching a high-pitched moan out of the smaller man.

Izuku’s hands on the sheets squeeze tighter, his back arching impossibly further.

And Katsuki just closes his eyes in bliss, the taste of needy (fertile, his animal mind supplies) omega on his tongue. His tongue licks languidly through Izuku’s chubby pussy lips, so wet and desperate for him.

Izuku squeals and shakes every time Katsuki’s tongue passes over his sensitive little clit, his whole body jerking and his hips grinding back against his face.

Katsuki groans at the feeling, swirling his tongue around the opening messily.

It’s practically gushing slick, readying itself for his cock and knot, and Katsuki’s never seen anything hotter.

The blond reaches up, his biceps just about the size of Izuku’s thighs as he circles the omega’s sensitive little bud as his tongue strokes over his slick hole.

“You like that, don’t you?” Katsuki asks huskily, expertly playing his clit. “You like your pussy being eaten by an alpha more than twice your age, huh?”

“Ah, yes-sahhh,” Izuku slurs, trailing off into a loud moan as Katsuki slips a finger inside.

“God, fuck, you’re gonna be tight on my cock, babydoll,” Katsuki growls, pumping the finger in and out, Izuku’s hole slick and eager but so tight and fucking /small/.

Izuku bites his lip, swiveling his hips in little circles, pumping back against Katsuki’s finger sweetly.

“Oh, baby,” Katsuki coos. “Trying to ride my finger. That good, princess?”

Katsuki stands and uses his free hand to yank Izuku’s head back with a firm hand in his hair, revealing the omega’s spit-soaked chin and blissed-out eyes.

“Stupid slut,” Katsuki soothes. “Open your mouth.”

Hearts dancing in his eyes, Izuku’s plush lips fall open submissively, looking up at Katsuki like he hung the moon and stars.

Katsuki, who smirks before spitting a wad of saliva straight down into Izuku’s waiting mouth.

Izuku squeezes around the alpha’s finger as soon as it lands, his pussy pulsing around the digit in orgasm.

“Swallow,” Katsuki orders, and Izuku does.

“Dumb whore,” Katsuki praises, pushing the omega’s face back into the sheets roughly.

Izuku whimpers pitifully when Katsuki slides another thick finger inside, stretching him out, not even close to enough for his cock.

The alpha’s hand is glistening with slick by the time he’s done sliding them in and out a few times, stroking Izuku’s weak spots teasingly.

“Wan- want it in,” Izuku begs, swallowing down the drool pooling in his mouth.

The omega feels high, high on pleasure, high on the feeling of an older alpha taking care of him like this, degrading him like this.

And then he feels the solid force of Katsuki’s body behind him, and everything suddenly feels real.

The thick head of the alpha’s cock brushes up and down his slit, wet and messy.

“Such a sweet little hole you are,” Katsuki whispers, biting his ear gently. “That’s all you are, baby.”

“Kacchan’s hole,” Izuku purrs drunkenly. “Kacchan’s slut.”

Katsuki huffs out a laugh at the nickname, teasingly dipping his cockhead into the tight pussy waiting for it.

“What else?” The alpha asks, just to be mean.

“W-wuhnna have Kacchan’s babies,” Izuku slurs, spreading his legs wider.

Katsuki snorts, imagining the media fiasco.

‘Forty-four year old number one hero knocks up nineteen year old college student’

But a deeper, more primal part of him darkens at the idea, balls throbbing at the thought of seeing Izuku round with his baby, nipples leaking.

Fuck it, Ochako always wanted a little brother.

With that, Katsuki presses inside in one smooth thrust, feeling himself ruining this pussy for anyone else, feeling it open for him like it never has before, tight and warm and fucking wet.

“Ah, ah,” Izuku moans pitifully, only able to bend over and take it, his hips held firmly in Katsuki’s strong hands.

“There we go,” Katsuki sighs, cock pulsing in that wet heat. “Pussy already knows who owns it.”

Izuku’s mouth falls open in a silent scream, eyes twitching violently as he’s filled by a cock that’s too big for his tiny pussy, stretched tight around the shaft.

Katsuki’s hips are pressed against the swell of Izuku’s ass, that tight hole somehow swallowing the alpha’s entire length.

The blond is pretty sure he’s in heaven, his abs tight with pleasure as he pulls out a few inches and shallowly fucks back inside.

“Ahn, K-Kacchan,” Izuku moans, the slow drag of Katsuki’s cock driving him up a wall, but he knows he has to get used to it, has to let his pussy adjust to taking something so big, even though all he wants is for Katsuki to hold him down and use him like a whore.

He’s taking the number one hero’s cock, holy fuck, pro hero /Dynamight’s/ cock. The man he’s looked up to since he was a child, now has him bent over his bed.

Katsuki’s hands on his hips still hold tight, firm and dominating and keeping him completely still as that cock pumps in and out, the pace slowly picking up until the blond’s heavy balls are slapping against his thighs softly.

It’s smoothed by how wet Izuku is, his pussy stretched too tight to even clench around the cock filling him up, unable to do anything but spasm on it desperately.

TBC fml hahahah 3 parts !!

Cw: daddy kink, chokin

Izuku isn’t sure how he got on his back, his thighs wrapped around Katsuki’s tight waist as he’s pounded into, but he isn’t complaining, his eyes practically dancing with hearts as he looks up at the older man, the blond’s face twisted in his own pleasure.

Izuku’s arms tingle around Katsuki’s neck, wanting to pull the man down into a kiss but feeling like he’ll be overstepping some type of boundary if he does.

Instead, he pulls him down and buries his face into his cologned neck, huffing down the firewood and caramel scent of pure alpha.

Katsuki has his hips angled up, fucking into him and sending his hips bouncing against the bed with every thrust.

The blond’s hips are solid with muscle, his whole body eclipsing Izuku easily, and the omega has never been so aroused in his life.

His pussy feels like it’s being split in two, big balls slapping against his ass and that thick shaft stretching him to his limit.

He’s always had an innocent crush on Dynamight, and befriending the man’s only daughter at college had been a dream come true, because as it turns out, the number one hero is even sexier in person, tall and broad and handsome as fuck.

Izuku had stumbled over his words the first time they met, so shy and nervous, but then he’d noticed the way Katsuki’s eyes lingered on his body. The way he watched his hips sway, his ass bounce.

It wasn’t like any of the other times Izuku has caught creepy middle aged men staring at him, no.

Instead, Izuku asked Katsuki to apply sunscreen on his back when he and Ochako were sunbathing, his heart pounding when those big hands lingered on his lower back.

He started dressing riskier, pussy clenching when he caught the older man staring at his ass in the mirror.

And now he’s here, under Katsuki like he’s always wanted, being railed into the man’s own bed.

One of Katsuki’s hands move down to toy with his clit, the other moving up to wrap around his slender neck and squeezing gently.

“You have no idea what the fuck you do to me,” the blond groans, pressing his cock in deep and grinding his hips in circles.

Izuku’s mouth falls open in a moan, squeezing his legs around Katsuki’s hips as he fucks in shallowly, cockhead feeling like it’s in his belly.

“Daddy,” Izuku whines, pressing his hips back into it, and his face reddens in embarrassment.

Katsuki stills for a moment, and Izuku’s heart drops into his stomach.

Oh fuck, he ruined everything, he -

Katsuki’s cock throbs inside of him, the grip on his neck tightening up.

The blond’s hips begin to piston at a brutal pace, and Izuku can only whimper as his airway is partially cut off, his pussy fluttering in arousal.

“Fuck, that’s so hot,” Katsuki all but pants, thick cock slamming into Izuku carnally.

The blond practically has him in a mating press, Izuku completely at his submission as he holds his neck and rubs his clit expertly.

“Harder, daddy!” Izuku moans out, clasping the hand around his neck to prompt him to squeeze harder.

Little fuckin’ freak,” Katsuki taunts, squeezing harder. “You like being daddy’s fucktoy?”

Y-yes!” Izuku screams, and he really hopes Ochako doesn’t come home early to hear him screaming for her dad. “O-oh god, you’re gonna make me cum on your cock, daddy!”

“Fucking do it,” Katsuki demands, both of their thighs soaked with slick as he ruins Izuku’s pussy for anyone else.

God, Izuku’s never gonna get fucked like this by anyone else, no one will ever compare - he needs Katsuki, fuck, always Kacchan.

“Uhn,” Izuku chokes out, his pussy tightening to alarming levels around the big cock inside, nearly sobbing when he feels the swell of Kacchan’s knot beating against his abused opening.

Stars burst behind his eyelids, shit, he’s pretty sure he sees the Milky Way galaxy in its full glory, supernovas and black holes bursting as he clamps down and cums, wetting Katsuki’s cock impossibly further.

“Good baby,” Katsuki groans, fucking into him like a machine. “Good fuckin’ baby.”

That thick knot is pounding against him, seeking his tight hole to lock around it and milk it for all its worth, his balls begging to fill up the young, fertile omega he’s owning.

“Get me pregnant,” Izuku begs, panting, so sure of his wishes. He needs it. Needs Kacchan’s babies - fuck, he’ll do anything to be the number one hero’s submissive little housewife, barefoot and pregnant and cooking him dinner every night -

The knot shoves inside with a brutal thrust, and Izuku screams up at the ceiling as his pussy is completely ruined and claimed.

“Fuuuuck,” Katsuki groans, knot throbbing and balls pulsing as he unloads everything he has to give into the little omega under him.

It just doesn’t stop, Izuku feeling like his womb is about to break as it’s filled with streams of cum, Katsuki’s big arm muscles clenching and unclenching as he fills him up.

“Take it,” the blond growls, still shallowly grinding into Izuku, his inner need to breed determined for his seed to take.

Izuku just flutters his lashes in bliss, nearly crying when those soft but rough lips press into his own in a deceivingly soft kiss.

Ochako comes back thirty minutes later, not noticing Izuku’s slight limp and sunny grin, and Katsuki’s relaxed aura.

Three months later, Izuku squeaks down at the positive pregnancy test, running to the bed to shove his face in his pillow with glee.

Katsuki gets home that night and his face softens with happiness at the news, and Izuku rides his cock in celebration - there are perks to living with the number one hero, lying to your best friend about moving in with a “roommate.”

She doesn’t need to know, yet.

The news will have to break soon - to Ochako, to the media, to Inko.

But it doesn’t matter how they react, because they have each other, always.
