After reading it, I wanted to try my hand at writing my own version of Kacchan getting into a sort of rivalry with an older Kouta over an ever oblivious Izuku! And thus, this is my attempt!
(:
Katsuki always knew he was destined for greatness, everyone always said so - focused their eyes on him and watched him overcome incredible feats, do incredible things. He fed off the attention; it fuelled his ego knowing everyone witnessed his awesomeness - saw him make something of himself! But all of those attentive eyes meant nothing compared to a certain pair of forest green gems that glittered with amazement and admiration whenever they fell upon him. If the attention from others fanned his egocentric ways, then those eyes gave him life as they watched his every action - revvering him as a true hero.
Worshipping Katsuki!
Those large pools of innocent green sustained him throughout the years - pushed him to become greater, supported him when he was down! Those jade depths that were always trained on him, observing and analyzing him, writing about him in a notebook dedicated to Bakugo, and Bakugo alone - only making his ego swell more. Big naïve eyes amazed by Katsuki's proclivity to shine with his Quirk - mimicking his characteristics, aspiring to be like him - enamoring Katsuki.
Emerald always fixated upon his rising figure - watching Bakugo carve his way to the top...
Those verdant jewels that sparkled beautifully when he did something heroic and was featured on screen; praised him for his amazing work and talent; filled with tears when they got lost within each other's passion. Those viridian orbs watched him grow - becoming faster, stronger and wiser - never losing focus of him even when they were stationed in different cities for a time. Those jade eyes never faltered - never strayed - remained beside him because he cared for him.
Katsuki had always thrived under attention, but there had only ever really been one person whose attention he really cared about - whose eyes he wanted trained on him as he took his place amongst the best!
And he'd do anything to keep those eyes on him...
So let it be known that Bakugo never exactly made it a habit to threaten kids. They were weak little things that needed protecting, even the obnoxious know-it-all teens, and only scum would take it upon themselves to knock them around. With some coaching from his friends, he'd managed to find a balance between intimidating and inspiring the little shits. He found them tolerable and not as annoying as he'd previously thought - helping his ranking remain in the Top 5. Katsuki never found reason to even think of harming a kid, let alone some stupid high schooler - felt his stomach churn whenever a villain would purposely target kids or when they would get hurt due to a villain attack.
But that all changed the day he let Deku change their plans - which started a chain of events that somehow led to Bakugo finding himself in this strange situation - preparing to get into a fight with some wannabe teen punk, all while contemplating how best to make the little bastard hurt...
And all for Izuku's attention...
It all started innocently enough, as most things do.
It was date night, and it was Deku's turn to pick what they did. The nerd's choice was the newest superhero movie and a meal of katsudon at this small, unassuming restaurant near their apartment; Izuku's favorite in town. They started their date without a hitch, meeting at the theater since Deku had plans with Ochako. It was Katsuki's turn to pay, so he bought their snacks and they headed into their auditorium. Deku practically danced in his seat the entire movie, too excited to sit still, wiggling around like a fucking child while whispering animatedly, making Bakugo wonder how the fuck Izuku could still act so childlike even though he was almost fucking 30... But nonetheless, Bakugo enjoyed the movie and hearing his nerd chime in his random nerd facts every chance he got in between stuffing his face with popcorn and drinking all of their sodas.
In the end, they finished their movie, Deku excitedly going on and on with more useless information about the comic book heroes than Katsuki cared to hear - he already knew all this from his own readings and Izuku's general ramblings - but he listened anyways as they ambled their journey towards their next destination. Since the theater and restaurant weren't far from their home, they decided to walk; it was a healthier option, and allowed for them to walk hand-in-hand - which Bakugo would never admit to liking as much as he did, but he did.
"What was your favorite scene, Kacchan?" The nerd asked as they roamed the streets, emerald gems turning towards him, nearly blinding him with their purity.
Deku had beautiful eyes; Bakugo could get easily lost in them.
But he managed to get his mind back on track, answering his nerd's dumb questions like they weren't meaningless prattle meant to fill the silence because Deku fucking liked to talk his ear off, especially about heroes.
"That's a stupid fucking question, nerd," the bomber hero scoffed, squeezing Deku's hand, relishing his warmth, "Obviously, the fucking kickass fight scene at the end, dumbass."
"I guess I should've known that'd be your answer, Kacchan," Izuku giggled, lips forming his signature blinding smile before he went off on another rambling tangent; Katsuki's heart raced like it always did when the damned nerd smiled at him.
Deku did things to him no one else ever could. Made Katsuki fucking love him in ways he never thought he'd be capable of expressing.
They continued on, and finally Deku decided to shut the fuck up, curling into his side, wrapping himself possessively around Bakugo's arm. It was nice, and the warm silence continued until they came to the entrance of the local park. The nerd stopped and tugged Bakugo's arm towards it, goofy smile plastered to his face.
"C'mon, Kacchan! Let's go through the park!"
The scenic route... if they took it, it meant it'd take longer to reach the restaurant though… longer to eat, which meant longer to get home and finish off their date like it normally ended - with them tangled and sweaty after a few rounds of fucking like animals. But Katsuki let his nerd avert their course through the small park anyway, relishing the comforting heat of Izuku's hold as they weaved past the few people still in the park this close to sundown. He couldn't deny he'd also chosen this path so he could hold onto Izuku a little longer
-and it wasn't like tonight wouldn't end in hot sex anyways, so they might as well take their time and enjoy it, right? And it was always nice to feel the nerd press into him like this when they went on dates, happily humming some random song as they went, making his chest light and his heart soar.
"What about you, nerd?" Bakugo asked after a while, tilting his head the nerd's direction as they strode through the secluded pathways, "What were your favorite parts?"
He could probably guess what Deku's favorite parts of the movie were, but in case the curly haired hero decided to surprise him, he'd like to know. He did pride himself on knowing the way his boyfriend worked, both inside and out - and if he was slacking in his observations about Izuku, then what kinda boyfriend would he fucking be.
"I'm sure you can guess it, Kacchan," the viridian hero smiled, eyes glittering with mischief as a rosy tint settled across his cheeks, voice low and husky, "You know me inside and out."
It was like Deku read his mind, plucking the words straight from his thoughts. And that sly look he wore made Bakugo's blood stir - made him realize how empty the park really was right now. It was romantic enough, dark and devoid of people, with a few lamp posts illuminating the few benches scattered about the pathways, and little people meant more privacy. Bakugo wondered if he could possibly convince Deku for a quick fuck in the park…
… It was worth a try at least…
Plus, the nerd couldn't say no to Bakugo Katsuki.
Katsuki growled, voice dropping an octave as he stopped in his tracks to pull Izuku closer for a searing kiss, hands settling on his waist, "I do know you inside and out, nerd."
Deku was quick to reciprocate, arms moving to wrap around his shoulders as Katsuki's tongue prodded at the seam of his lips for access. The blonde was granted entrance, the nerd's pert tongue slipping out to play with Bakugo while the bomber hero maneuvered them to the nearest bench, lips connected the entire time as he sat down; Deku quickly perching himself on Bakugo's lap, ready to devour Katsuki.
"Not gonna even bother pretending you're not into this?" Bakugo smirked against Izuku's voracious lips, hands slithering down to grope at the nerd's plump thighs, eliciting a groan from the verdant hero.
"No use lying to you, Kacchan."
Katsuki's smirk grew, "Fucking perv."
"Only for you."
Izuku gasped when the blonde's hands found their way to his ass, giving a rough squeeze that had the freckled hero grinding against Bakugo for more friction.
"Deku," he rasped back cheekily, hands still massaging away at the globes within his grasp.
The nerd's hands quickly found their way to Katsuki's belt, fingers hastily fumbling to undo it as his lips paved a hungry path down from Bakugo lips towards the blonde's throat, teeth nipping voraciously, mouth sucking greedily and hard enough to leave marks. He was eager and desperate, hips grinding down into Bakugo's lap.
Oh yeah, Deku was definitely fucking into the idea.
And Katsuki was more than willing to follow through with fucking on this public bench in the middle of a public park. Someone could easily walk in on this. It was risky to do this out in the open; it could put their images as heroes through the wringer; it could be a PR disaster.
"Fuck."
But it would be so fucking worth it! If Katsuki wasn't hard before, he most certainly was now picturing the scenes unfold before him as his dick sprung free of its confines, night breeze hitting his heated flesh causing a groan to escape him. Izuku giggled against his neck, breath teasing Bakugo's ears as his deft fingers wrapped around Katsuki's length; warm, a sharp contrast to the previous chill.
"Fuck," the blonde groaned again, bucking his hips up into the nerd's enclosed fists.
Deku chuckled again, tongue swiping against the shell of Bakugo's ear, causing shivers to go through the vermilion-eyed hero while Izuku teased him, breathing out a sultry, "You're just as much a pervert, Kacchan."
Cheeky fucking bastard. Bakugo fucking loved him to pieces.
"Fuck me," Bakugo sighed, biting down into his lips to keep from making so much noise. Izuku was into this a lot more than he'd thought, and it was fucking hot.
"Maybe if you're good, Kacchan," came the teasing response, which was quickly followed by fingers expertly moving up and down his dick just the way he liked it. Deku really knew him too well, and if Katsuki weren't made of sterner stuff, he may have came in his pants in that moment.
Another moan rumbled out of him as he peered into Izuku's mischievous eyes, desire burning bright. Bakugo was left breathless, ecstasy rolling throughout him as Izuku's touch quickened, wrist flicking in time with his upward pulls. He couldn't deny the nerd definitely knew how to work him; his green eyes stayed focused on Katsuki as he licked his lips, hunger darkening their depths until his eyes became large black pools with thin verdant rings.
Bakugo wouldn't lie, he was a bit of a narcissist, and knowing Izuku watched him - wanted him - made his blood run hot like liquid magma in his veins.
What did he do to deserve such a fucking perfect soulmate!?
Katsuki opened his mouth, ready to command the nerd to ride him right then and there - to satiate them both. He was super fucking horny, and Deku was too if the way he rut against him was any indication, mouth slightly parted. Bakugo wanted to be inside the nerd already!
"Midoriya."
"Hm?"
But it wasn't his voice that rumbled the nerd's name in the dark. It came from the side, from the darkened path, causing Deku to quickly scramble off Bakugo's lap onto his feet, shielding him from the on-comer's sight and instantly souring the bomber hero's mood as he hurriedly tucked himself away. With that, he turned his head to glare at the nosy bastard, cursing them to hell for stopping his tryst with Deku.
Who fucking knew how long it'd be before the nerd tried sex in public again! And now he fucking had blue balls damn it!
"Long time no see."
And that's when he fucking saw Izuku blush hard, heat spreading across his freckled cheeks as he glanced at their intruder, fidgeting with his scarred fingers. That was an action solely used with Katsuki when the nerd was nervous about something, hands constantly moving - with anyone else he mostly resorted to chewing his lips, trying hard not to let others see his discomfort. His writhing hands were very obvious and noticeable signs, which meant Bakugo was the only one privileged to observe the verdant hero at his most naturally awkward.
Or at least, he was fucking supposed to be!
"Kouta-kun?"
Envy quickly filled Bakugo, and he just had to see the fucker making his boyfriend so flustered - had to see first hand who he had to add to his shit list.
No one made his Deku act so squirmy but him!
And that's when he saw some fucking teenage punk standing there in the dark with his hands in his pockets, trying to look fucking cool, a smug look on his face as he watched them. He might've pulled it off - looking badass, if it weren't for his stupid fucking face and that shitty hat.
Who the fuck wore a dumb fucking hat like that anyway, and why the fuck was it familiar?
"What are you doing here, Kouta-kun?"
The name sounded familiar as fuck too, but Katsuki couldn't place it. He assumed it was probably a fucking hardcore fanboy or some shit, as Deku made it a habit to learn some of his more enthusiastic club members' names; he'd been a fanboy himself, and probably understood the gravitas of a being acknowledged by one's hero.
"I was just passing through and I thought I saw you."
The dick named Kouta strode towards them, stepping into the luminescent area with a smirk on his face as he eyed Bakugo with a shit-eating grin, like he'd gained some giant triumph over the bomber hero or some shit.
"I hope I'm not interrupting." He said nonchalantly.
Fuck this fanboy!
"Oh, not at all," Izuku flailed his arms in the fidgety manner of his at the same time that Katsuki glared at the blue-balling brat with venom in his eyes, "Yeah, you fucking are."
Fucking cuck.
Deku turned to give Bakugo a flustered look, and Katsuki met his look with the same annoyance he directed at the fucking kid. But the nerd simply turned and gave the fucker a nervous smile as he wrote the blonde off, "Ignore, Kacchan. He's always so grumpy."
No he wasn't - just when bratty teens ruined their mid-date fuck!
That smarmy smile spread further on the asshat's face, and based on the brat's attitude, Bakugo would bet the fucker knew exactly what he interrupted, and did so on fucking purpose.
"It's good to see you."
That smirk seemed to grow even more if fucking possible, before the little shit replied with, "Likewise. I haven't seen you since I was in middle school getting ready for entrance exams, Izuku."
Katsuki seethed while he glared murderously at the insolent fuck who thought he could just let his nerd's name slip past his lips - like it was alright for him to be so fucking personal with Bakugo's Deku. The snot-nosed kid smiled back just as smugly, mischief glimmering in his squinty fucking eyes. Bakugo decided then and there he didn't like this little fucking cocksucker - didn't like his stupid fucking face, his fucking cocky attitude, his shady fucking eyes, his fucking way of saying Deku's name like he just fucking could, or his fucking belief that he could just fucking go about interrupting two fucking adults trying to fuck in a public park like he was - was - was…
Fuck, he couldn't even think properly through the mist of rage!
"Has it been that long?!" The nerd gasped. The fucker took a step closer while Bakugo silently seethed.
Back the fuck up!
"Look."
The little shit had the gall to put his grimy undeserving fucking hand on Deku's head, ruffling his curls to emphasis their height difference - the motherfucking passage of time.
Bakugo stood from the bench then, towering angrily behind Izuku, scowl plastered to his face, eyes narrowed murderously on the teen, drawing another amused glance from the brat.
Don't fucking touch Deku!
He could tell the punk got the message as he moved his hand back to his side, saving his fingers from being broken.
"Oh wow!" Deku exclaimed, oblivious to the silent threats Katsuki was sending his fanboy as he gushed over the fucker's height.
Izuku was shorter than this asshole, but Katsuki was taller than the fanboy, and he had to resist the urge to tower over this insolent bitch who dared to be so familiar with his nerd. He wanted nothing more than to tear this punk ass twerp in half. Katsuki glared openly, palms twitching with anticipation while he contemplated murder and where he would stash the kid's fucking body. He'd leave no trace that this cuck ever existed…..
And burn that motherfucking hat too, just for good measure!
"Kouta-kun!" Deku's eyes sparkled, angelic smile spread across his lips as he closed the distance between them, "You've gotten so tall!"
He watched, jealousy brewing within him, making him want to hurl.
He wanted to snap at the intruder to hit the fucking road, but he knew that'd upset his nerd if his stupid demeanor towards this smarmy bastard was any inclination. Bakugo surmised it must be some punk from his fan club; Deku always made time for his fucking fans.
'They're the reason I'm a hero, Kacchan!', he could practically hear Deku say.
Bastard was lucky he wanted to keep Izuku happy, and he knew barking out insults or showing aggression towards one of his fans would upset the nerd, but it didn't stop the growl that rumbled past his lips; it seemed Deku was too far up this little prick's ass to notice though. The intruding fucker wasn't oblivious however, as his beady eyes flickered to him for an instant with a self-satisfied gleam before focusing back on Izuku.
Fuck this stupid kid!
"I guess I have," the little shit stain smirked, "But have you shrunk? I remember you being so tall."
The nerd laughed like it was the greatest fucking joke ever said, and it irked Bakugo, fists curling angrily at his sides as he tried to remind himself to control his fury. He couldn't maim a kid!
...At least not in front of Deku.
"You just hit a major growth spurt, that's all!"
Deku was visibly fawning over the brat who towered over him, unaware of the gleam that shimmered in the guy's shady fucking eyes - the way the shithead watched him. Bakugo's teeth ground into each other hard as he glared at the two men, trying his best to stay put - to not wrap his hands around that scrawny kid's neck and commit oh so tempting murder.
"I'm gonna graduate high school soon, Izuku," the shithead beamed with a smirk again, breathing out Deku's name like he was setting a trap, trying to lull the nerd in, "I'm finally gonna be an adult now - get to do adult things..."
Katsuki's eyes narrowed dangerously on the kid as he took an involuntary step forward, palms twitching with the urge to use his Quirk as the dipshit let his grating voice peter out, black eyes shifting to Bakugo in that satisfied way. What the ever-loving-fuck did this brat just fucking say!?
He was leaving very obvious hints about what adult things we was referring to. He didn't fucking like this - Izuku's sole attention was focused on this stupid cockblocking loser - and he didn't notice this fuck face was looking to encroach in on Bakugo's fucking turf. There was only one fucking reason he'd have to announce his comment like that - all while ogling Deku like a juicy piece of meat.
He's mine, you fucking shit!
This teen dirtbag was a fucking predator on the hunt, and his prey was Katsuki's stupid, kind, always-too-fucking-friendly Deku. Another growl rumbled out of him, once more drawing the fucker's eyes for a moment, and Bakugo saw the challenge hidden in his shady eyes, like he was promising to steal the nerd away from him. But this asshole was fucking mistaken if he thought he could just waltz up and snatch Deku away from him!
Dead fucking wrong!
"Wow!" Izuku exclaimed again, stars dancing in his verdant eyes, unaware of the challenges passing between the two men, "I remember when you were so small! You barely reached my chest back then! You've really grown so much, Kouta-kun!"
...Wait… what?
Katsuki focused on the brat's stupid face. Black eyes. Black hair. Red horned hat... Recognition hit the blonde immediately, crimson eyes widening. It was that snot-nosed brat from their first U.A summer camping trip! The crybaby midget who punched Deku right in the jewels! Izuku saved this punk from the muscle amplifying shitbag with the League of Villains -
Deku's first fucking fanboy!
- the fanboy Izuku kept in contact with all these years! The fucking kid Deku used to hang out with religiously before his hero career and their conjoined adult lives took precedent! The fucking bastard that Izuku kept tabs on occasionally and spewed about every now and again!
This fucking brat idolized Deku… and Izuku adored this fucking asshole!
Fuck me.
"Well, now that I'm older," the bastard murmured as he stepped forward even closer, lust burning in those beady fucking eyes and the blonde's vision went bloodthirsty red.
Oohhh no. No. No. No. No.
It seemed that hero worship had turned into sexual attraction! And even if Deku was fucking naïve and stupid, Katsuki wasn't! This motherfucker was trying to preposition his nerd on a fucking date and more adult things!
MOTHERFUCKING NO!
Bakugou fucking lost it, teeth grinding together as he moved.
Fuck no!
The cuck leaned down towards Izuku, bringing his face so close to the nerd's, "Maybe we can-"
This kid had a motherfucking death wish!
So before he could further contemplate fulfilling his fantasies of murdering this fucking cockblocking kid, Katsuki stomped his way in between them, hurriedly grabbing onto Deku and throwing him over his shoulder with ease, all while snarling at the blue-baller with vehemence, "Fuck off, kid!"
This shit needed be reminded where the fuck he stood with Deku - what the difference between Bakugo and this dirtbag was - why Izuku would choose a motherfucking adult like Katsuki over some smug fucking kid!
"Kacchan!"
Surprise registered on Izuku's face, almost as if he'd forgotten he was even fucking there - only adding to his rage - and before more words could be exchanged, he hastily made his exit, leaving that shitty fucker in his dust.
"Kacchan!" Deku whined again, flushing bright red at being manhandled so roughly in front of his admirer.
But Bakugo wasn't having it. He was fucking done watching that shitty asshat flirt so fucking obviously with the nerd. And Deku was too fucking stupid and biased to realize it
"Shut the fuck up, nerd!"
Behind them, they heard the shithead call out, "See ya later, Izuku!"
Like fucking hell!
Katsuki gnashed his teeth together and sped out of the park at a full sprint, using his Quirk in one hand to propel them further much quicker - not allowing Deku to say his goodbyes - not wanting to ever see that little shit again!
Needless to say, Bakugo's jealousy got the best of him, and rather than head for the restaurant for their meal like intended, he rushed them home and away from the bratty fucker. Lips and teeth nipping and biting as hands grasped bruisingly onto freckled flesh the moment they walked through the threshold of their apartment. Clothes flew about the floor, heavy breaths mingling as their bodies collided, skin to skin. The bed creaked beneath their weight, the nerd panting out his lover's name beneath gliding fingers, sweat beading their bodies as thrusts became fast and erratic. Katsuki was determined to remind the fucking nerd whom he should be paying attention to and praising, whom he should look at with stars in his fucking eyes.
Just watch me, Deku!
Deku should pay attention to what he fucking had before him - to Katsuki!
And only Katsuki!
His eyes should be glued to him just like they always had since they themselves were children, and not some insolent punk who thought he was the hottest shit around!
Keep your eyes on me, Izuku!
Bakugo didn't know it yet, but this was were it would all start - how a simple choice like taking the scenic route to their restaurant of choice, or stopping to fool around in the park would lead him down a path were he would enjoy the thought of beating some smarmy kid's ass and try to accomplish that goal at any cost.
If you haven't already read the amazing piece that inspired this, I highly recommend giving it a shot!
