Work Text:
"At this rate, you're gonna get me fat!" Izuku whines, patting his full stomach. It was more teasing than complaining, a cute joke because Katsuki had once again cooked really good food that'll probably keep him full the whole day.
"Wouldn't mind if you are." Katsuki says truthfully as he shrugs, leaning over Izuku to affectionately nose at his cheek. Izuku would be cute, he'd decided, in any form. Even when Deku was still a lanky, awkward middle schooler, Katsuki had wanted to sink his teeth into him over and over again like a delicious snack.
Deku flushes brightly at the admission, still vulnerable as ever towards Katsuki's constant praise. "Kacchan!" He giggles, pawing at his boyfriend's chest playfully, making the blond grunt as he pretends to sway from the weak hits. "You're so sweet!"
It was both of their day-offs, the couple having decided to stay at home instead of going out for today, mostly because of how much hero work was weighing down on Kacchan, and Izuku's career being more demanding than it has ever been in his years that he'd been a model.
The day goes by with ease, and by the end, Izuku was on Katsuki's lap, the older man busy as he sends out emails and texts while his little boyfriend taps away at the first-person shooter game at his phone, squawking whenever he dies earning an amused rumbling chuckle from Katsuki whenever it happens. Thankfully, Izuku's quiet whenever Katsuki had to make a phone call, overall tame while he works with the exception of the occasional lip pucker to ask for more kisses, or a full body stretch that ends up almost always accidentally knocking Katsuki in the nose- but it was alright, because Izuku was cute.
"Hey sweetheart," Katsuki coaxes Izuku awake with a gentle shake, peppering his cheek with kisses- tempted to sink his canines into his freckled cheeks, unable to get enough of him. "Get up, it's time for bed." Izuku stirs with a vague murmur of what sounded like Katsuki's name on his lips, eyes fluttering sleepily when the blond presses a soft kiss on the corner of his brow.
Izuku pouts, petulantly squeezing his eyes shut as he clings onto Katsuki's shirt. "Oi, brat." The man scolds, but doesn't do any further protesting- instead, he hauls Izuku up in his arms easily, arms hooked under plush thighs as Deku automatically wraps his arms around Katsuki's neck. "You're spoiled."
And yet Katsuki's hands don't leave him, even as they climb into bed. Deku obviously relishes the skinship, snuggling closer as if trying to meld the hard plains of Katsuki's body to his softer ones when Kacchan tugs the blankets up to shield the both of them from the cold of the apartment, heater too far away for either of them to bother to get up. Izuku doesn't really care, though, because the blond's body naturally runs hot due to his quirk, and the warm palms smoothing down his back made him give a happy sigh.
___
"Do you think it'll fit, Ochako?" Izuku says, out of the blue, eyes dreamy as if he'd been floating on cloud nine as he idly twirls his cute curls around a gloved finger.
"Do I think what will fit?" His agent- and best friend asks, used to the way Izuku blurts out whatever he's got in mind. She always trusts him to explain later anyways.
Then, Izuku turns to her, fluttering those doe eyes that always captivated the audience, before he runs a finger down his shoulder to his elbow, tracing the smooth skin there. Uraraka feels herself tense a little. Midoriya was somehow unnaturally beautiful, which added to the whole appeal that judges talked about- though, to her, it made the brunette quite uneasy how Izuku was almost always able to get his way just with a wink or confident roll of his eyes.
If, in the chance he did not get what he'd wanted, the status of his boyfriend- number one pro hero Ground Zero- would.
Izuku hadn't done anything nefarious, no, not at all- partially why Ochako was ashamed of being slightly scared of her best friend- but just the knowledge of Izuku's position, higher and more powerful than what others may guess- was enough to make her feel jittery for weeks. Hell, the boy's notoriously affiliated with All Might, the ex-number one hero, along with numerous government officials that chat him up as if they're all old friends with Deku after grand shows and openings. His influence stretched around the globe, as the first quirkless model, having a large impact using both beauty and brains.
If Izuku hadn't already explained he was quirkless numerous times to the media, Ochako would think he had some sort of persuasion power- or at the very least, a beauty one as well.
But Izuku was Izuku, and with or without a quirk, he'd manage to dominate the modeling and media world the moment he debuted- popularity on an even more explosive growth ever since he'd announced that yes, Ground Zero was actually his boyfriend.
Ground Zero was another matter entirely.
Quick to anger, snap, and explode, the number one hero was seen as a symbol of Victory as he wiped the shit out of villains and came out a winner every time. Despite the aggressive front that has yet to die down, the hero was terrifyingly sharp and intelligent, 'brash' movements calculated for minimum casualties and maximum damage towards villains.
His ranking plowed through every single competition, winning in both popularity contests and actual hero work. The bold, fiery hero was probably refreshing, and to the new generation, All Might's assuring "I Am Here" smile pales in comparison to Ground Zero's sharp, devilish smirk after another win.
Katsuki was already surpassing the old heroes, uprooting the decade old hero society structure and forcefully paving the way by shattering the concrete that solidified inhumane expectations towards heroes. It showed that he'd succeeded, despite not being the poster boy of heroics with that perfect smile and niceness.
"Pisses me off," Bakugou had rolled his eyes during an interview. "Seeing these losers act as if they need to be perfect to get to number one. Here I am, with a shitty mouth and dickhead attitude, but at the end of the day, I win and save. That's what heroes are meant for, to be pillars for the people, not fools who run around with their heads up their asses worrying about those dumb popularity polls and appearances."
Bakugou was admirable, really. The both of them were, so when their relationship was confirmed, they'd been declared a powerhouse couple, thanks to news magazines and popular internet sites.
They were terrifying.
Not only because of their influence that causes ripples in society as a whole- but because Ochako was pretty sure the only reason neither of them had taken over the world was because they're too busy being enamored with each other to be considering world domination.
Today's world revolves around heroes and popularity, and Katsuki and Izuku were both the perfect examples of being the ultimate upholders of the current generation, even if they're unknowing or not.
But of course, Izuku was too worried about what his hubby will eat for dinner than to sweet talk his multiple government friends into making him king or some shit- while Katsuki was so enamored with Izuku that outside of the decisions he makes for hero work, he'd bend over backwards if it meant he'll have Izuku smile, meaning being too busy bringing Izuku whatever he wants.
Speaking of, Deku stopped lazily tracing his arm, a large grin on his face. "I'm talking if I should get Kacchan's initials tattooed on my arm."
Ochako almost chokes.
"A t-tattoo!?"
"Mhmmm," Izuku giggles, almosy feverish at the thought. "Kacchan has lots of tattoos already, and I wanna try.. besides, he has one on his chest that has the letter 'I' on it. Y'know, for Izuku."
Ochako almost faints. "He already has a tattoo dedicated to you!?"
"Yep! He got it the first week we'd been dating."
"THE FIRST WEEK!?"
___
"Kacchan," Izuku whines, leaning up to kiss his boyfriend on the lips. Katsuki blinks, surprised at his sudden appearance, before leans down to accommodate the height difference.
"Deku." Katsuki greets, still in full hero gear aside from the arm braces, relaxing in his spacious office after the ungodly amount of paperwork caused by Kirishima accidentally flinging a villain into the bank down town- something he profusely apologized for through offering to take care of half of Katsuki's workload.
It was a pain in the ass, really, but Gale Force's team took care of the damage since it was in their district, and it was somewhat Inasa's fault Kirishima lost control over the villain due to him activating his quirk without a callout, causing wind to slam into both the heroes and villains.
"What are you doing here? I thought you had a shoot?" Katsuki won't say it, but if it were possible, he'd keep Izuku at home, to be able to indulge him, keep him safe. The feeling used to be dull, but it evolved strongly after Izuku was taken hostage in one of his shows by a shitty villain who thought he'd get an advantage on Katsuki using his love life- but Katsuki wasn't fucking number one for nothing, and he makes sure to blast the shit out of the fucker.
He would've killed him too, his hand already around the criminal's neck, ready to rip open his throat with a bang, but fucking Izuku held his shoulder and pouted, though a demanding look was in his eyes, still in the tattered clothes he'd been modeling in.
"I wanna kill him too, Kacchan," Izuku whines, so close that his breath ghosts over the shell of Katsuki's ear and making his grip tighten around his throat. The man gags, writhing like a pathetic bug. "But everyone will see you, and I don't want you to lose your license."
So Katsuki pulled back, disgust on his face, quickly quelled by Izuku's soft lips pushing on his. "The cameras are looking," he whispers between breaths of his sweet kisses. "Game face on. You won this time."
And Katsuki forced his malicious anger down, the thoughts of killing the man with a single blow- reigning in bloodlust and making it settle into something rotten in the pits of his stomach as Izuku flashes his award winning smiles as reporters rush over to badger him whether or not he's okay. He is, of course, and the medics arrive soon after, and they take both Katsuki and Izuku in for a custom check-up after a villain attack.
Bakugou refused to part with his boyfriend, gratefully taking Eijirou's offered jacket in favor of draping it over him, nodding at his best friend silently as they made their way to the hospital without much of a hassle.
Katsuki wanted to be delicate, after they got home and Izuku clambered over him, eyes dark as he rolls his hips gently right over the blond's crotch, face pink and cute dick already hard and straining in his pants from getting worked up during the apprehending of the villain. "You were so hot," he'd whimpered when Katsuki bucks his hips, hissing under his breath when pleasure and arousal shoots through his body in ribbons. "You were going to kill him, for me, for me," Izuku's lower lip trembles, almost sickly manic at the thought Kacchan was ready to take a life because he laid a hand on Izuku.
"I wanted to see you blast his fucking throat," Izuku giggles breathlessly, riding a high, "Wanted to- fwuah- wanted to see you kill that sorry fucker for me."
Katsuki supposed he should be worried about Izuku getting turned on about murder- but he couldn't care less when his dick twitches in his pants and suddenly he's all over Izuku, fucking roughly into the tiny little brat and sinking his teeth right by the small cuts he'd sustained from the fucking villain, making sure they were deeper, lasted longer- to mark him.
In present time, Izuku giggles, presenting a bento box shyly. "Uhm.. I wanted to try cooking for once because I feel bad if Kacchan's always responsible so I searched up a recipe online.. I hope you like it!"
Katsuki snorts and pops it open, walking to his desk as Izuku hovers behind him, unsurely eyeing the food.
It was chopped up pieces of mango for dessert, with a simple recipe of rice and fried fish in the middle, carrot slices cut into clumsy little flowers that made Katsuki coo fondly. "Looks good, sweetheart," he assured his nervous boyfriend. "Bet it tastes even better."
It.. did, to an extent, a little bit more on the salty side- and the rice was a little mushy, but Katsuki wolfs everything down with enthusiasm, the only image in his mind being Izuku floundering around in the kitchen in an effort to make his Kacchan the perfect meal. He'd give it ten out ten fucking stars, especially when Izuku's proud, watery grin tops everything off when Katsuki places the chopsticks down, satisfied as he pats his stomach.
"So fucking good, nerd," he ruffles his hair, and Izuku gives a little cheer. God, when was the fucker ever going to stop being adorable? Probably never. It almost makes Katsuki want to chain him down in their bedroom forever- but that's a thought he's going to save and bury deep, deep inside him. For later. "You wanna try other recipes with me?"
And Izuku smiles, bright and brilliant, holding Katsuki's hand. The blond thinks that yes, he would give everything up if it meant having Izuku all for himself.
"Let's go, Kacchan!"
___
"Kacchan, oh my gosh, Shindou's over there!" Izuku whips around, giving the blond puppy eyes. "Can I go over and say hi?"
Of course Katsuki shrugs, giving his date a quick kiss before sending him off. Surprisingly, seeing Izuku chat that Shindou prick up didn't make him tick with jealousy. He wasn't that jealous of a person, after all- Katsuki knew that at the call of his name, Deku would come running towards him first.
Instead of acting like a protective mother hen, Katsuki tears his eyes away from Izuku- stomping down the fears of his cute boyfriend getting groped underneath his flowing outfit- dress almost robe-like and see through- only under the right lighting and close up, of course. Last time it happened, he broke the shitty hero's nose and sent the fucker straight to the hospital, cancelling the event.
Right now they were at a hero gala, a day after the rankings were announced. It was not mandatory, but Katsuki loves showing off his cutie of a boyfriend at any chance he gets, so he took the offer and signed Deku in as his plus one.
He'd taken into account Izuku's hero fanboy complex, knows that he'll probably start shaking in excitement the moment they step out of the car, knew that the little dork would be running around for autographs- at least, from the ones he hadn't met through Katsuki, anyway.
It was boring, without Izuku by his side, Katsuki admits as he idly sips the expensive champagne in his hands, standing around and occasionally giving a curt nod to fellow heroes. It went on like that until he decided to pull out his phone and just scroll through his socials- before pulling up Izuku's official modeling profile and admiring the new released pictures of a new clothing line on a popular brand, reading the paragraph of thanks and congratulations in the description along with the thousands of comments that praised Izuku and put him on a pedestal.
It was so cheerful and chipper that Katsuki snorted in amusement- almost forgetting he was at the gala- before the smell of heavy lavender soaks his nose and a tap on his arm makes him recoil. "What?"
The woman blinks, as if taken aback by his snappish nature. She was dressed almost regally, a dress that hugged her curves tightly, clothes lined with gold frills and red gems, delicate chains braided into her hair- and that must be her quirk, because the edges of her brown hair blended into full bodied snakes, writhing and hissing as she carelessly bats the creatures away from her face.
"I'm hero Medusa," she smirks, confident and head held high. Katsuki wasn't even paying attention, really, watching as his short husband attempted to touch a buck hero's antlers all excited, a smile curving his lips as the giant of a hero seems to be enamored- even leaning down so Izuku could touch the massive horns sticking from his head. His friends laugh around him, watching Izuku with both apprehension and shyness.
"-excuse me, Ground Zero? Helloo? Anyone home?"
It was supposed to be a lighthearted joke as the woman waves a hand over his face, a try hard pout on her lips as her snakes writhed on his shoulders. It annoyed Katsuki, very much so that he drops his lips into an unamused frown, making it known that he was uninterested. "Would rather not," he combs his hair back to purposefully flash the tattoo of an intricate ring using red and black ink- one that symbolizes a promise ring.
With his explosive quirk an actual ring would probably shatter at the first use of his power- that, or it gets lost during a fight. A chain around his neck was a bad idea as well, since if it were light, it would just snap- or if it was thick enough, it would simply be used as a choking device by villains.
So Izuku pushed to get matching tattoos that of course he couldn't say no to.
The woman was.. persistent, leaning into his bubble-
"Come on, Ground Zero! I'm-"
"Kacchan!"
The chirrup call interrupts them, and Katsuki almost sighs in relief if it wasn't for the sharp smile on Izuku's face, twisting his features angrily at the sight of them. "He's with me," Izuku clears his throat, taking his rightful place by Katsuki, leaning his head into the blond's chest with his teeth bared.
Aghast, Katsuki dumbly watches Izuku make a degrading shooing motion with his hands, as if to cow a dog, to which the Medusa woman responds by going red and stiffly marching away. Izuku gives him a sweet smile, looking as pretty as ever, leaning up to place a kiss on his lips before tugging him down to whisper in his ear. "Take us home, Kacchan."
Obviously, Izuku was on edge- and Katsuki furrows his brows, nodding protectively as he excused himself from the circle of friends that approached him- Kirishima almost striking up a conversation until Izuku gave him a rough pull and his smile got even more strained. A puzzling reaction- one that made Bakugou's stomach clench up in worry. Was Izuku sick? Was the room too cold?
Once they made it into the private parking lot, Izuku pushed him into the backseat, roughly pushing his gray coat away. "Oi," Katsuki chuckles lightly as his persistence, but slips the coat off all the same. "What's got you worked up?"
"That bitch," Izuku grumbles, almost working himself into a frenzy, face strained in an expression Katsuki had never seen before. He'd never seen Izuku so- angry, red- it made his belly flutter when he slips off the robe-like top to reveal beautiful porcelain smooth skin. "I hate her."
"Hey hey, calm down," Katsuki placates before Izuku could strip himself further, holding his shoulders. "C'mon baby, why are you so-"
"I don't like the way she touches you," Izuku hisses, eye twitching at the memory of that stupid fucking- "As if you're hers!"
Katsuki rubs Izuku's waist assuringly as his boyfriend rants, trying to ignore the uncomfortable hard-on in his pants, straining against Izuku's thigh. No doubt the shorter man feels it too- angrily rolling his hips as he verbally tears the flirty hero down.
"You know I'm yours." Bakugou murmurs, inhaling sharply when Izuku leans into his space and buried his nose in his neck, small mouth latching onto his pulse and sucking a bright red bruise on there. Teeth drag down his skin, sending little explosions of pleasure and a thrill down his spine, especially when Izuku pulls away to flutter his pretty lashes, looking absolutely stunning under the blue moonlight seeping into the vehicle. "I'll always be yours, you know that."
Izuku pouts, and Katsuki actually feels sorry- "I know Kacchan," he whines, thick, plush thighs squeezing Bakugou's hard cock through the dress pants, making the blond choke and hold his breath, counting to three to contain his patience. "I jus' didn't like her shoving her tits into your face."
It was unfair, how cute Izuku was saying those vulgar words- ripping a surprised laugh from Katsuki as he squeezes his waist. At that, the younger man quietly giggles along with him. "I wanna ruin her," he whispers, more of an afterthought than an actual confession. "I wanna kill her career off.."
Katsuki feels the familiar spark of fear and breathless wonder light in veins on fire. He really shouldn't be condoning this- Izuku was being irrationally dark, a sharp contrast to his soft side. It should make him worry- maybe even feel concerned enough to question him or shove him into therapy, but he couldn't deny the excitement that makes his body feel on fire and the natural will to bend to Izuku's demands.
It was all too much.
"Then do it."
Izuku's eyes widen in surprise and awe at the serious tone Katsuki takes, the blond's red eyes zeroing into his, burning with fiery passion and a tinge of darkness- like a snake eyeing his prey. "Kacchan.."
A sick grin splits Izuku's lips- and Katsuki treasures the expression, admiring how honest he was being, with his desires.
Katsuki gives a charming wink, kissing the tip of his nose.
"Jus' don't get yourself in trouble, baby."
___
(Nobody mentions how Hero Medusa's rankings tanked- and how in the next hero gala, she was nowhere to be found.
Izuku rolls his eyes after surveying the area, clinging onto Katsuki.
Good riddance. It didn't even take time to dig around for dirt on her, anyways. The leaked videos of her being a bitch towards interns had dragged her down into the top two-hundreds almost immediately.)
____
"I have a s-surprise," Izuku shyly ducks his head, fingers anxiously threading through the fabric of his hoodie. "I hope Kacchan likes it.."
Katsuki blinks up at the younger man, kneeling on the edge of their shared bed, immediately shutting his laptop and pushing it to the side. He wanted his full attention on his boyfriend, wanted Izuku to know he was listening- and god, does he look absolutely tempting with his plush thighs squeezed and rubbing together nervously, a cute blush painting his delicate face.
"Well," Katsuki says mildly, reaching out a hand to squeeze Izuku's. "What is it baby?"
Izuku takes an inhale, as if to gather his shaky courage up. "O-Okay. Uhm, here," he grabs the edges of his hoodie and pulls it off in one fluid motion.
Katsuki swears his breath was knocked out from his lungs, eyes widening at the sight of a tattoo, a simple etching of the letter "K", overlapped neatly by beautiful pink cherry blossoms and lotuses situated by his lower right rib. "Damn," Katsuki says, giddy at the sudden excitement rushing through him, almost euphoric as he gently skims the edges of the art piece. "Fuck, Izuku. You all mine?"
"Mhm," Izuku nods, feverishly agreeing. "Yours, Kacchan."
"I should take a picture and frame it in our living room."
"Kacchannn!" Izuku whines, giggling when the pro hero scoops him up in his arms and plops him on the center of his lap. He's careful to not irritate the tattoo, running his hands all over his cute Deku. "The guests will see! That's so embarrassing!"
Ah, Katsuki mildly thinks, as he play fights with Deku, watching his nose scrunch up and release when he successfully smacks away his hands. I want to eat him up.
But it does mean he'll hurt Izuku- and he's not too fond of that idea. Keeping him on a tight leash so he's safe sounds better, protecting him from another villain attack.
The last one was almost a tipping point to Katsuki, adamant on resigning due to how his hero work caused Izuku to get hurt- but the dear thing was as bullheaded as him and fought to shake him into sense. Katsuki was fucking weak towards his Deku, of course, and let off of the two weeks resignation notice only if Izuku promised to get a bodyguard and perhaps a hundred padlocks in their home.
Was it overprotective?
Yes.
But Katsuki would rather have that than Izuku dead.
"Arms up darling."
"Mh-m'kay."
Izuku obeys easily, hands above his head as Katsuki cradles his side and fluidly slips out his phone, snapping a picture of the tattoo and making Izuku shyly flush at the clicking of the camera lenses. "So beautiful," he praises, and the model giggles when Katsuki kisses his cheek. "Good boy. I'm done."
Later, around bedtime, Izuku's the first one to be sound asleep as Katsuki noses into his green tufts and lets the scent of strawberries and pine fill his lungs. There in the dead of the night, he lets his feelings out- the sick, the disturbing.
"I want to lock you up," Katsuki murmurs, confessing that wretched thoughts that constantly plagued him when he sees every smile, every shine of green eyes- "I want to keep you all to myself. I want to have you exclusively- fuck, Izuku, I want to chain you down so you won't ever fucking leave."
The hero's teeth graze soft, silk skin- over his baby's neck, throat, resisting the urge to bite. After a minute or two of hungrily kissing all over Izuku, he inhales to calm the fuck down before settling into his pillows, eyes shut. When he'd slipped away, the earlier presumed asleep Izuku blinks, and flushes, smile wide and crooked- face sickly red as his body practically trembles in utter excitement after the little tirade his dear Kacchan had whispered into his ear.
He's perfect, Izuku thinks, heart giddy and ecstatic, bursting with love that makes him cover his mouth and muffle a squeal. Kacchan, KacchanKacchanKacchan-
The model takes a sharp inhale, calming his rapid heart beating at the speed of a rabbit's. Still, the mere thought of Kacchan thinking that, cherishing, him it was, it was-
Love, love love love, his mind sang, gleeful. Kacchan loved him, so much. And Izuku loved him back- he'd gladly give himself to Kacchan- make him happy. Being by his side, whether as a model or as perhaps a mere trophy, Izuku simply wanted to be with Kacchan.
Snuggling closer into the warmth his dear partner exuded, heart trembling dangerously in his chest, Izuku drifts off into a deeper sleep- ready for his photoshoot tomorrow.
-
It was almost inevitable, when it happened.
Izuku knew his thoughts and feelings towards Kacchan were disturbing- Katsuki, on the other hand, thought of his own dark narrative of love and possession as something normal, good, even. Who wouldn't feel like that for someone like Izuku, after all?
Izuku, who was everything sweet, nice- soft and fearless, unbelievably talented, gorgeous, with untamable fluffs of silk hair and green emerald doe eyes that cowed everyone in the same room. He was intelligent, and charismatic, having clawed his way to the top through his silver tongue and fluttering lashes- a massive, destructive whirlwind barely contained by his small body.
That's who Izuku was, and Katsuki didn't know what he did to deserve him, to be incredibly fucking blessed. But the blond was selfish, and despite knowing he's never done anything to earn Izuku, he wanted to have him forever.
Deku's behavior acted like a conductor to Katsuki's own attitude, encouraging, even.
It should be disgusting how he wanted to have Deku cuffed in his room, wanted to trap him, eat him up, devour him whole. But even Katsuki knew that birds never belonged in cages that small- Izuku certainly was meant for the limelight and fame, the attention- the money- and to take that all away just because he craves him twenty-four seven made the blond's chest feel hollow.
Though, with feelings like that, having been always pushed down and left to boil- there was always, always a tipping point.
Always.
Izuku knew this, Katsuki knew this- so it wasn't a surprise, when the green haired man came home after a shoot, a week after he'd gotten the tattoo, and found Katsuki hovering over someone sprawled out in their living room.
The smell of burnt flesh made Izuku wrinkle his nose, though, he doesn't care, not when Katsuki was breathing hard, a calming exercise that his therapist had taught him for anger. The veins on his neck practically struggled against his skin to burst, hands dripping with red. The rug imported from Thailand complete with intricate designs was unsalvageable from the streaks of blood and burnt edges, cherry-wood coffee table crisp and shattered into splinters.
"Oh, Kacchan," Izuku cooes, quickly making his way over to him. "Baby, are you okay? Did he hurt you?" He waited for the blond to compose himself, wrapping his arms around Katsuki's middle to the blond's surprise.
"He fuckin' pissed me off," he hums, and Izuku tries sneaking a peak down to the man's face, a smear of red in the corner of his eye- but Katsuki shushes him gently, turning around to bury Izuku's face in his chest. "Don't look, sweetheart. Bastard doesn't deserve anything from you."
"Nnn," Izuku pouts, but his eyes flutter close at the familiar smell of expensive cologne and smoke from pricy cigars he'd always been fond of. "Okay..."
Katsuki chuckles, kissing his forehead warmly. "Go upstairs, I'm gonna follow after I wash my hands."
"But the body..."
"I'll ask fuckers to deal with it," he shrugs, before pressing a noisy kiss on Izuku's jawline, making the ticklish model shriek in laughter. "Be good, baby. I'll be right with you."
-
Fifteen minutes pass when Katsuki finally creaks open the door to their shared bedroom to find Izuku happily humming by his vanity, patting his freckled cheeks with marvelous skin care, glossing pretty pink lips with butterfly chapstick- the one that Katsuki got for him yesterday. He was unbothered, tilting his head to shine a gorgeous smile at Katsuki despite the prior bloodshed that stained his living room.
"Kacchan!" He chirps, and Katsuki crosses the chasm between them before gently cupping his face and placing kisses all over Izuku.
"Little birdie," Bakugou muses, enjoying the soft sighs Izuku slips between kissing. "I'm sorry, got fuckin' mad."
"What happened?"
Katsuki's eyes sharpen before he hesitantly confesses. "He talked too much about you. Ran his mouth about you, your body.. Pissed me the fuck off. Nobody talks about you like that except me."
The hero's griping led Izuku to look up at him, eyes soft but dilated, biting his lower lip as he'd subconsciously inched closer, immediately attracted to the buzzing, volatile anger that seemed to prickle under his boyfriend's skin. "You're amazing," he whispers, sincere and blissed. "Always taking care of me, oh Kacchan.. what would I do without you?"
Flattery, but it was, as always, sickeningly genuine. Izuku had always been the honest one, after all, when it came to feelings.
Katsuki rumbles, pleased at Izuku's delighted purr as he carries his cutie to bed, pushing aside the.. sticky situation with the corpse in the living room.
It was a fuckin' journalist, who'd promised Katsuki to be able to talk about Izuku more- and oh, he loved talking about his fucking boyfriend so he'd agreed to meet at their home while Deku was away.
He should've known, with the way the extra's eyes scanned their numerous pictures together in their home, the way his disgusting gaze focused on Izuku on particular, the nasty lick of his lips, his prying eyes-
Fuck, the way he'd talked about Izuku like he was a little dolly plaything he'd gladly break-
Katsuki still felt the ecstasy in his veins when he'd pushed his palm into his throat and without knowing, detonated an explosion that rocked both their worlds before the extra could even beg for mercy from Bakugou Katsuki.
The adrenaline rush was particularly nasty, better than any hero fight, with the subject of his past anger being thrown in cuffs instead of Katsuki being able to burn their throat from their body. Something about killing the journalist was satisfying- his scream turning into murky gurgles as he grasped desperately at his throat for nothing because Katsuki's muscles weren't just for show.
It was almost comical, watching the man miserably failed to pull away from Katsuki's iron grip before his quirk heated his palms, eyes wide and then-
Boom .
The first thought was, good riddance, and then followed by, Deku's fucking mine.
"Kacchan!"
The whine pulled Katsuki out of his thoughts, and he realizes he'd been running on autopilot, dick hard and straining against his trousers, shirt already off. At the same time, Izuku was messily sprawled on their black silk sheets, mouth in a cute 'o' shape as he gasps for air, lips swollen and red from the abrupt make out session that felt like Katsuki was trying to eat him.
He was in a similar disarray, the picture of perfect, fluffy robe undone to show slivers of baby smooth, freckled skin, and plush thighs that were blushed pink from squeezing against the sides of Katsuki's torso.
Hunger roared to life in the blond's stomach, a beast wanting it's fill- the prey being Izuku, who shyly giggled and squirmed under his gaze.
"Baby," Izuku whimpers. "You won't get in trouble would you?"
"I'm the number one hero. I fucking wish they would try."
At that, the same sharp, feline smile tugs on Izuku's lips and oh- Katsuki realizes, they were the same.
Izuku didn't care that he'd killed someone with his bare hands- liked it even, if it was the adorable little chirps and him grinding against Katsuki's thigh was anything to go by.
"Love Kacchan, I love Kacchan, love love-"
"Love you too, Izuku," Katsuki hums, before leaning down to claim these lips again, riding the high after a kill. "Love you too, baby."
-
Life went on the same.
They were a power couple, through and through, the perfect role models, placed on high pedestals that no one could knock them off of. Katsuki won and saved, and Izuku flashed gorgeous smiles for a pretty penny, donating to Quirkless colleges and all that goody two shoes shit.
The only difference was the killing.
"Deku."
"U-Uhn.. this.. this is what Kacchan feels right?" Breathless, ragged, manic- "this, this is- feels good, good-! Haha-!"
Katsuki's smirk widens, and he grabs Izuku before he works himself up into a frenzy, shivering from adrenaline and eyes twitching as the knife falls out of his grasp, leaving a full view of the very clearly.. dismantled body in the garage. The unknown extra was covered in angered, excited slashes, cut up and beyond unrecognizable as blood trails smeared all over the walls and floor- hell, even the ceiling.
"Shhh, bunny, calm down, alright? I could feel your heartbeat." Katsuki hums, nosing at Izuku's hair as his boyfriend shakes in his grip, giggling to himself- and the blond catches a few words.
"Fucking bitch.. hitting on Kacchan... mine.. who does she think she is?"
"Deku? Baby?" Katsuki couldn't hide the flush of his cheeks or the way his fucking heart squeezes at the cute way Izuku looks up, blood splattered to join his freckles, the green in his eyes a simple thin ring as his pupils had swallowed up the rest.
"She's the- the bitch from your agency- the new secretary.. Kept trying to come onto you, right in front of me too- fucking whore-"
"Yeah yeah, that's it, get it out." Katsuki holds him tightly in the embrace, forcing Deku to calm the hell down- but his dick betrays him by twitching at the thought of Izuku's jealous murder frenzy. "My baby's first kill.. good boy. I'll call the cleanup crew okay?"
Katsuki was a patient man, he really was. He'd calmly dialed- ahem, 'janitors', to take care of the garage situation, bathed Izuku to watch the blood wash off of him easily. He'd avoided every attempt of the feral little thing to try and engage Katsuki, desperately riling him up after riding the high of the first kill he'd ever done.
Poor Izuku was almost animalistic, unconfined, now that he'd let loose once. He was rutting up at Katsuki in a frenzy, his eyes watery but lips pulled into a snarl, a dangerous combination of aroused and wrathful- just right to make Katsuki hungrily lick his lips as he wrapped Deku up in a fluffy towel to dry off his damp hair.
By then, Izuku's state had marginally tapered off to something easier to handle. His heart was still thrumming like a hummingbird's, but he was more present than before, just quieter and eager to soak up Katsuki's presence, scent of blood now gone and leaving his usual floral smell.
Only then, does Katsuki truly pin him down into the sheets and have his way with him, biting, marking wherever he could reach until they were both sated and Izuku's throat was scratchy from him screaming his name.
Deku got his own little marks in, Katsuki finds out, feeling the sharp sting on his back from Izuku raking his nails down while he'd roughly pounded into the little minx.
Thankfully, it seemed like he'd fucked all the fight and buzz out of Izuku, who was currently half-asleep, curled up with his head on Katsuki's chest and hands fiddling with Katsuki's rough and calloused ones- particularly the one with the promise ring tattoo.
In moments like these, Katsuki felt the familiar warmth of fondness flood his chest, a feeling he'd sink his teeth into to never let go. Pushing that aside, he pulls the blankets up to Izuku's shoulders, idly playing with his hair as they simply soak in their time together in a blissful quiet.
".. Deku," he grunts, making Izuku still. "Why'd you kill her?"
"Nnn.. jealous. Kept hanging off Kacchan whenever I came to visit."
Katsuki blinks. Oh. He'd never even noticed the woman, eyes and mind always trained on Deku only. His tunnel vision probably caused him to be ignorant of the possibility of other people trying to hit on him instead of everyone being all over Izuku.
"I left her a fake note in your writing to meet at home," he admits, before pouring up at Katsuki, the expression making the blond feel utterly weak. "You're not mad, right, Kacchan..? I had to do it. I had to, because she was-"
Katsuki is quick to shush him, kissing the crown of his head with a foreign gentleness reserved for Izuku only. "It's okay darling, breathe, don't work yourself up. If it does comfort you, I don't even know that extra's name. If anything bothers you like that again, tell me, okay baby? We'll take care of it, together."
"Together?" Izuku's eyes shine- and they both know what that means.
Katsuki had promised to kill as a team.
"Together," the hero confirms, before chuckling and carding through Izuku's hair with his own fingers. "Sleep. I know all that action's fuckin tired you out."

Killing was almost second-nature.
It was as easy as breathing, a simple task that had easily acclimated itself into their schedule. Strict rules were applied, though.
One was never more than three per month. The high crime rates would look abnormal, especially since the area is where aground Zero himself lives- making it seem like one of the supposed most protected towns.
Two, was to always have a safe alibi. In a world of quirks, it was quite easy to find someone with an illusion power to make it seem like number one Ground Zero and beauty model Midoriya Izuku were at a gala when they were getting busy in their blood splattered garage, cleaning the latest kill.
Lastly, no killing without each other. Nothing for safety reasons, just the fact that Izuku gets a massive shot of adrenaline after his little murders that Katsuki has to fuck it out of him after to make sure he doesn't go on a spree- while Izuku simply liked watching Kacchan work because it was amazing to get to see Katsuki work.
It worked out for them, and with Katsuki being number one and Izuku being fucking adored, it was easy to dismiss rumors. Easy to ignore their.. escapades, when Katsuki always brought home victories against villain's while Izuku landed Japan on top world model lists.

The whole world erupted in cheers when Japan's power couple finally got married, met with congratulations from politicians, heroes, and fans alike, their union was received with celebration when they met in a kiss at the altar.
Izuku was in fucking bliss, and Katsuki was floating on top of cloud nine, finally married to Bakugou Izuku- able to call him his husband. God, did he love the ring of that.
Izuku, the sweetheart, chatted with Uraraka and Iida, rosy and always beautiful- flushing deeply at the excited praise that his friends offered to him.
"You really are a catch, Izuku," Ochako sighs happily, content for her best friend as she clinks martinis with the groom. "If anything, Katsuki's the lucky one."
"I'm inclined to agree." Iida says, jokingly as he subconsciously fiddles with his gelled up hair, slicked back for the occasion. He was soft, usual uptight demeanor gone- Izuku deserved to relax on his wedding day, after all. "Say, where is your honeymoon?"
"Oh, Kacchan said it's a secret," Izuku giggles, flustered as he thumbs at the white veil around his shoulders. "He's sweet like that, wants me to be surprised."
Ochako grins, hearty as she knocks back her drink. His best friend hooks their arms together, and Izuku's helplessly pulled into the dance floor.

Two days later, they arrive at the small island, just teetering on the edge of Japan. There was a nice, spacious home located and nestled cozily in the trees- and Izuku finds himself struggling to carry his bags.
His Pro Hero husband is quick to swoop in, giving his ever charming smirk as he lifts both the luggage and Izuku up with startling ease, palm resting on the plush of Izuku's upper thigh, before giving a nice squeeze. It makes Izuku's heart flutter.
Katsuki knew how much he loved the sea side, the glistening water early in the morning- the dreamy look of clouds. Here they were, on their honeymoon at an isolated island with just that and a private settlement where they'd get to soak up each others' company before things got busy in the real world with magazines and hero shit they'd both eventually get swept up in.
The private island was rented by Katsuki, along with the boat and other unimportant expenses. Shit wasn't even a massive blow to his wallet, ever since he'd hit number one. He'd realized how easy it was to afford everything he'd wanted and more when he was top three- and of course, Katsuki made it his personal mission to spoil the living hell out of Izuku, especially now it was their honeymoon.
Now they stood on the brick pathway, leading them from the sandy shores to the most perfect, quaint little interior that they were supposed to live in for the weeks they're staying.
With total isolation and privacy, Katsuki couldn't help but let his mouth stretch into a sadistic grin. Izuku catches on, by then, and oh- he smiles back, eyes poisonous.
"All set, Ground Zero?" The man of the yacht Katsuki had but just for this location hums, a crooked, but friendly smile on his lips as the hero nods approvingly. "Alright, we'll be back the moment you shoot us a message. Enjoy your stay for your honeymoon- and, well, congrats, sir. We'll see you."
Only thing left was..
"No no, we've been at sea for the longest time!" Izuku gasps, lashes fluttering as he tilts his head, cute pouty lips making the captain waver. "Stay, for one night, please?" The man hesitates, looking over to Katsuki- who gives his best, charming smirk.
A victim.
"Deku's right," he rumbles- and the stupid stars that appear in the man's eyes makes his insides sing and hands itch. He can't wait to tear into him, see Izuku giggle and cheer, covered in blood- "stay the night, captain. Dinner is on us."
And just like everyone, just like the whole world, the magazines, the gossip lines, the news- the man sighs, pleasant and deceived.
"Well, only if it's okay with the both of you, sirs."
Izuku tilts his head, almost shy- but Katsuki could see the hungry twitches of his fingers as he earnestly claps the captain's hands with false naivety.
"Oh, don't worry! It really, really is."
