Katsumi Midoriya (formerly Bakugo), Japan’s Number Two Hero, had a big fucking problem. Namely, that she was seven and a half months pregnant and horny as all fuck.
These things were absolutely, definitely related. Katsumi had always known what she liked; she’d never seen the point of hiding it or being ashamed of it. She’d known she got turned on thinking about being pregnant for years. Call it whatever you want, a pregnancy fetish, a breeding kink, a goddamn obsession, Katsumi had it. She’d never been able to get off without imagining herself being knocked up, held down and pumped full of cum…that sort of thing.
Even now, having to work around her obscenely swollen belly, Katsumi could only whine needily as she rubbed her fingers into her sopping wet pussy, curling them inwards and rolling her hips in a desperate search for something, anything, to grind against, to give her enough friction to vent some of the maddening heat filling her whole body. She was lying on the couch in their living room, upper body propped on a pillow and some inane bullshit playing on the tv-not that she was paying attention, of course. All her focus was on the slick, quivering mess between her thighs, as her fingers played over her clit and groped at her swollen, milk-heavy breasts. And yet, despite the burning pleasure swirling in Katsumi’s core, the release she so desperately needed simply refused to come.
This was absolute hell. She’d been horny all fucking day, and being on maternity leave meant that she couldn’t even find a villain to beat up to blow off steam! No, she had to rely on her husband to satisfy her, and the bastard was out at work still, leaving her here to stew in her own arousal for hours on end.
Yep, pregnancy hormones were definitely a thing-and it was ten times worse when just being pregnant was the single greatest turn-on Katsumi had ever experienced. From the moment she’d first found out she was up the duff, Katsumi’s body had been in goddamn overdrive. Literally anything could set her off now and leave her desperately needing to cum. She’d had a healthy libido and an active sex life before getting pregnant-now it was a hundred times worse.
Katsumi returned to the futile mission of trying to make herself cum, but it simply wasn’t happening. She’d been trying for hours, and yet despite how easily her pussy moistened, how much pleasure her growing, milky tits and huge round belly filled her with, she just couldn’t cum.
It was fucking pathetic. She was the Number Two Hero, for fuck’s sake! Villains everywhere feared her! And yet here she was, mewling and whining on the couch, loose-fitting maternity dress hitched up halfway on her belly, turned into a complete quivering mess with no hope for release!
And then, finally, salvation appeared in the form of the front door opening.
“Kacchan, I’m home!” Katsumi’s husband called out.
Instantly, Katsumi was moving. Enormously pregnant and bloated she may be, but she still had the reflexes of one of the most powerful heroes in Japan. She barely remembered to cover herself back up, yanking down her dress to cover her soaked thighs, before she was charging- absolutely not waddling, Katsumi did not waddle-down the hall to greet the man who’d done this to her.
Izuku Midoriya, as always, beamed when he saw his wife. “Hello, love,” he said sweetly. “How was your day?”
Even through the all-consuming lust, Katsumi couldn’t help the surge of happiness that filled her at the sight of him. She and Deku had been together for fucking years; as far as Katsumi was concerned, she’d been with him ever since middle school, one way or another. High school, UA…they’d been dating the whole time, much to the amusement, and sometimes horror, of their friends. Katsumi had never cared what other people thought, though. She’d always known they were meant for each other.
But damn, if Katsumi couldn’t still appreciate the goods. The dinky little nerd she’d liked back in middle school was long gone. This Izuku Midoriya, still carrying the case with his hero costume in one hand, was a six-foot, divinely sculpted Hercules, his body filling the doorway as he stepped inside their home. One For All and becoming the Number One Hero hadn’t just made Deku into a household name and Izuku into a living legend; it had made him hot as sin.
Because of that, and because hours of edging herself into oblivion had dramatically reduced her already very limited patience, Katsumi didn’t reach out to give her husband a welcoming kiss, but instead grabbed him by the collar-no easy feat, as she barely reached Izuku’s chest.
“Shut the fuck up,” she growled. “Bedroom, now.”
Despite recognizing her tone of voice very clearly, and being more than capable of gathering the context clues necessary to understand why his very pregnant wife was practically leaving a trail of her own juices dripping on the floor, Izuku held Katsumi’s gaze easily-because on top of everything else, Izuku Midoriya had, at some point in their relationship, gotten the slightest little bit cocky. Then again, he was married to Katsumi Motherfucking Bakugo, so, he clearly had something to be pleased about.
“You alright, babe?” he murmured in a voice so low and sweet that Katsumi got pissed off at herself for feeling another pulse of arousal go through her just from hearing it.
She yanked on his shirt again, trying desperately to hurry up and drag him into the bedroom. “I’ll be better if you hurry up and get in the goddamn bedroom, you shitty fucking nerd,” she snapped.
Izuku raised an eyebrow. Katsumi’s language had never really changed, exactly, but it had softened in some ways, at least in what she meant; “Deku” and “shitty nerd” had long since become terms of affection for her, much as his own nickname for her had. It was the product of two people who’d known each other all their lives, still finding new ways to express their love for each other. But right now? Katsumi was clearly out of it, and the sheer desperation on her face would have worried him, in another situation.
But as it was…Izuku took a sniff. The whole apartment reeked of female arousal. Katsumi’s scent filled the entire space, her pregnant body throwing off chemical signals that no man could possibly miss. She’d driven herself wild with lust, and stood no chance of resisting.
Izuku grinned, and the sight of it sent a shudder down Katsumi’s spine. That was the grin he wore only for her, the one that meant that he knew exactly how to make her fall apart, how to turn the Symbol of Victory, Bombshell herself, into a whining, begging, completely submissive toy.
That was the other truth Katsumi had always known about herself, and that Izuku had discovered in bits and pieces as their relationship developed. Under it all, under the aggression and the anger and the incredible skill for violence, Katsumi was a complete sub. She’d let Izuku do anything to her…so long as it fulfilled her breeding fantasies, of course. Not that he could possibly complain about that, given how fucking hot he found the idea.
Well, it wasn’t just an idea anymore. So Izuku looked at his horny, pregnant wife, set down his costume, and said, “Lead the way, Kacchan.”
Despite being a head shorter than her husband, hugely pregnant, and on the verge of collapsing just from the thought of finally having some relief, Katsumi managed to haul Izuku bodily through the door to their bedroom and chuck him onto the bed in record time.
“Stay right fucking there,” she snarled as Izuku went to rise. “And get those goddamn clothes off now.”
Izuku raised an eyebrow, even as he obliged her request. “So bossy,” he chuckled. “What’s gotten into you, Kacchan?”
“Your fucking kid’s gotten into me,” Katsumi growled. “I’ve been horny the whole fucking day, Deku! Hours of trying to get off, but I couldn’t manage it!”
As she spoke, she tore off her own clothes; the dress, loose anyway and with nothing else underneath it, rapidly pooled at her feet, kicked aside with the sort of disdain only Katsumi Bakugo could muster. She turned back to the bed, only to get stopped in her tracks.
Izuku was staring at her, and his eyes were hungry. He seemed to drink in the sight of her, bare as the day she was born, pale, flawless skin shining in the evening light pouring in from the bedroom windows.
She grinned, understanding that look perfectly. “Like what you see, nerd?” she asked pointedly, cocking her hip as much as she could, given the awkwardness of doing anything with as pregnant as she was.
It worked magnificently, as Katsumi knew it would. Pregnancy absolutely agreed with her, and she made it look fucking fantastic. Katsumi had never been a particularly large woman; her build had always trended towards favoring speed and agility over brute strength. She had a gymnast’s body, built for movement and power and fluidity, with a narrow waist and slender legs and breasts that had, before her pregnancy, been rather small. She’d always had a fucking glorious ass, though-as Izuku could personally attest to.
However, her pregnant belly had not gotten the size memo, it seemed. It looked incredible on her slight frame, a vast round curving dome that swelled up her belly, filling her frame out in ways that looked unfairly good. She seemed to be at least 50% belly by volume, as if being pregnant was her true purpose in life, and her body knew it. Nor was that all-her breasts had ballooned out, now seemingly twice their original size, spilling down the shelf created by her pregnant belly to rest pertly on her chest, capped with hard, dark nipples that were slowly dribbling milk from their tips; that was a new development, one that Katsumi was very excited to give Izuku the chance to enjoy. Her hips and ass, too, had grown rounder and lusher; it was as if she’d gone from a woman to a fertility goddess, and she knew it.
More than that, she knew that Izuku couldn’t resist the sight of her. He stared at her with eyes that seemed to glow in the evening light, and Katsumi shuddered, imagining the kinds of things Izuku was thinking of doing to her.
“Like” isn’t the right word, Kacchan,” Izuku murmured, dark and velvety.
She took a step closer. “Then what is?” she asked sweetly, red lips curving into a grin.
She drew closer and closer, until at last she slipped up into the bed, now less than a foot away from Izuku, her whole body burning with need for him. He was naked now too, and his cock was already fully hard; how could it not be, looking at her? She imagined she could feel its heat from across the room, pulling her closer.
His arms came out to encircle her, drawing her in and up into his embrace. Katsumi felt her skin ignite wherever he touched, fingers running from her neck down her back, her sides, and across the rounded front of her belly, caressing and claiming.
Izuku leaned in close to her ear, and hissed, “You’re fucking magnificent, Kacchan.”
Katsumi whined. “Y-yeah,” she breathed, feeling her pussy grow wetter just from his voice . “I am.”
Izuku hummed in agreement. “Fucking look at you,” he whispered. “Sometimes I can’t believe that you’re mine, you know that? That Katsumi Bakugo is pregnant with my kid.”
Katsumi whimpered. He’d pulled her so close, she could feel his cock against her, gently stroking against her pussy, not entering, not yet. “That’s right,” she said softly. “You did this to me, Deku. Made me yours. Stuck your dick in me and made me into this.”
Izuku pressed a kiss to her neck, then another to the point just under her jaw that was her greatest weakness. She nearly turned to jelly in his hands, a whimpering sigh of pure, unadulterated need escaping her lips.
“What did I make you into?” he asked. “Say it.”
Katsumi bucked her hips, ever so slightly, but she knew this game. She and Izuku played it regularly; it was another way they’d always been in sync, their kinks and their desires lined up so perfectly she knew that they were always meant to be together. They’d been having sex for a very long time-ever since high school, when they’d had to sneak around so their parents didn’t find them (not that that had worked, as Katsumi had once had her goddamn mother walk into her bedroom as Izuku was pounding her into the mattress.) They’d learned each other’s bodies, their preferences.
That was what made it second nature for her to answer, “This-this pregnant slut who needs your dick…who spent hours trying to make herself cum, only to realize I need the real thing…”
Izuku grinned, and guided Katsumi to straddle him completely, cradling her belly gently, letting her take the lead.
“If you need it so bad, Kacchan,” he told her, “then it’s all yours.”
Katsumi needed no extra encouragement. Immediately, she lowered herself down, guided by the weight of her pregnancy-altered body and long years of knowing the absolute best way to fuck Izuku.
His cock pushed into her steadily, making her whine with fulfilled pleasure as she sank down to the base of his shaft. No matter how many times they fucked, Katsumi never got tired of it; it was like she and Izuku were made for each other, knew exactly what the other liked and how to drive them wild.
She rolled her hips, and hissed as hours and hours of tension practically drained away; it only took a few moments for her to find her rhythm, and soon she was bouncing at a steady but quick pace, her thighs slapping against Izuku’s hips as she rode him.
“Fuck yes, Deku…” she moaned. “Please, fuck me…”
It was rare that Izuku was this passive in bed; often, he was greedy and assertive, a side of him that rarely came out except with Katsumi; it always made her laugh, to know how all their friends thought he was so sweet and innocent. They’d never seen the things she’d convinced him to do to her-even if they had had to put away some of their more intense toys once she got pregnant.
But then, as his hands stroked over the curve of her hips, running possessive fingers down her full, swollen belly, perhaps it was just that he was appreciating the sight and sensation of his pregnant, horny wife fucking herself stupid on his cock.
And fucking herself stupid was the right term for it; as Katsumi picked up the pace, her pussy clamped even tighter around his dick, her heavily-edged senses fraying already. She’d been waiting for this for far too long to take it slow; she was trying to milk him dry.
Even as she slammed her hips down, feeling his cock hammer at her insides, Katsumi felt like getting some things off her chest. Leaning forwards and planting her hands on Izuku’s broad chest, she fixed him with her angriest glare.
“This is all your fucking fault, you stupid Deku,” she growled, biting her lip as his cock rubbed against a particularly perfect spot. “You put this fucking baby in my belly, and it’s ruining me! I can’t beat up villains, I can barely walk, my tits are giant and sore all the time, and all my goddamn organs are punching bags for your fucking kid!”
Izuku raised an eyebrow, even as he held back his own pleasure. “You’re blaming me for this, Kacchan?” he asked, amused. “Remember how you never let me pull out? How you wrapped your legs around me every time and screamed for me to breed you?”
Katsumi’s response died out and turned into a desperate whimper as her pleasure mounted. She rode his cock faster, trying desperately to fill the howling, all-consuming need in her loins. She needed to cum so fucking badly.
It was more than that, though; it was the way Izuku’s words reminded her that, yeah, despite how fucking much she loved fighting villains, she liked this just as much. Being fucked and filled with cum until she finally got pregnant, being bred, carrying fucking Deku’s fucking babies. She loved it, more than anything else.
Sensing his moment, Izuku seized it with the fury that only the Number One Hero could possibly have mustered. He rose up to meet her, making Katsumi whine as he sat up and pulled her down deeper into his lap, pushing his cock even further inside her. Her pregnant belly jutted out into the space between their bodies, pressing against Izuku’s abs as she clung onto him for dear life. He thrust up from below, taking over as his arms encircled her body, making Katsumi howl with pleasure, burying her face in his neck.
As he fucked into her with a vengeance, making her body shake and quiver with pleasure, Izuku leaned down to press his lips to her ear.
“Look at you, Kacchan,” he breathed. “Falling to pieces like the pregnant slut you are. Completely helpless when my cock is inside you, knowing that I’m going to breed you. You can’t beat this feeling, and you know it.”
Katsumi cried out, unable to suppress her ecstasy any longer. “F-fuck you, Deku,” she whimpered. “I’m gonna-“
Izuku growled back at her, a deep, dark, possessive sound that tickled something raw and primal in Katsumi’s soul, something that exhilarated in drawing those sounds, those feelings, out of her smiling, loving husband.
“That’s right, Kacchan, cum for me,” he murmured. “Come apart around my dick, let me fill you with my cum like I’ve been doing ever since you realized you were born to have my kids. You know this is what you were meant for, isn’t it? Being round and swollen and pregnant…and milky.”
As he spoke that last word, Izuku pulled away from Katsumi’s ear, and moved his lips down her body, grazing them across her neck, her collarbone, and down to her breasts. With one hand, he took a hold of one of her swollen, obscenely full tits, and squeezed, while pressing his lips to her dark nipple and sucking as hard as he could. A few moments of this treatment got him his reward: a few steady drops of white milk, trickling from Katsumi’s tits as if she was a cow.
That feeling, the feeling of Izuku drinking her milk as he fucked her pregnant pussy, the feeling of being loved and cherished and bred to within an inch of her life, was too much for Katsumi’s poor overstimulated brain. Hours of trying to cum culminated in a single, completely mind-melting orgasm, her whole body locking up for a few impossibly long seconds as her brain went white and she came her goddamn brains out. “D-DEKUUU!” she howled as she climaxed, her sopping wet pussy squeezing down on Izuku’s cock, as if it hadn’t gotten the memo that she was already so heavily pregnant and was trying to get her knocked up all over again. Sure enough, a moment later he came, too, groaning as he pumped her full of cum, thick ropes of it painting her walls white.
When people asked her why she loved Izuku, Katsumi had a lot of options, most of them so sappy she’d be required to immediately murder anyone she ever admitted them to. But there were plenty of other reasons she was head-over-fucking-heels, and one of them was the fact that he knew exactly how to use her breeding kink to break her fucking brain.
It took a little while for Katsumi to be capable of human speech again; by that time, Izuku had already eased her off of his cock and maneuvered them both into lying down on their sinfully amazing bed, luxuriating in the bliss of release as Katsumi snuggled up against her husband, all her furious pent-up energy finally released.
Burrowed against her husband’s side, thoroughly fucked and tired out, Katsumi muttered, “Enjoy this while you can, Deku. I’m not gonna be so easy with the next one.”
In response, Izuku chuckled, the deep, rolling sound rumbling in his chest, making Katsumi snuggle harder into his side. “The next one, eh?” he asked. “Already making plans for getting knocked up all over again?”
His reward was a red eye peeking from under his arm, fixing him with a baleful glare. He just grinned wider; scary as she might be, Katsumi was seven months pregnant, and he had just fucked her senseless until she literally broke. That tended to make a man slightly incorrigible.
Katsumi eventually just sighed, and-somehow managing to not sound quite so begrudging-muttered, “I love you, you stupid fucking nerd.”
Izuku smiled. “Love you too, Kacchan.”
Katsumi Bakugo really did have it all. A legendary reputation, a kickass heroics career-not to mention the best fucking husband a girl could ask for. She couldn’t wait to meet their kid…or to give them a couple of little siblings. Only a couple, though. Like, two, maybe? Or three? Four? Who was counting, really?
What? She knew what she wanted-and what she wanted was as many of Izuku Midoriya’s kids as possible. Fucking fight her.
