All Is Fair In Love And War

Summary:

It takes Bakugou Katsuki having his heart blown out and dying once to realise three things about himself.

One, he is in fucking love with Midoriya Izuku.

Two, he would die and kill for Izuku.

Three, he would do anything and everything to have Izuku by his side.

And when he means anything and everything, Katsuki means anything and everything.

Notes:

Hi, everyone! I had this spicy, yandere Katsuki in my head for the longest time, and what better way to share it than for the Finale KTDK event?

This is my slightly twisted post 431 fix-it fic, and I hope you enjoy this as much as I had fun writing it.

PS: It’s my first time writing yandere Katsuki. I was hella nervous writing and sharing this, but I hope you guys enjoy this yearning yandere Katsuki.

PPS: I reread this and found some of the scenes lacking. So, I edited some parts and added a tad bit more delicious scenes. From 10K to 12K, it’s better now, I think. If you have read it before, read it again and enjoy the fun twice.🤭

WARNING: I forgot to include a warning before, so I did it now. As this is a slightly twisted post 431 fic, PLEASE MIND THE TAGS.

Without further ado, I present to you ‘All Is Fair In Love And War’. Enjoy!

(See the end of the work for more notes.)

Work Text:

Bakugou Katsuki has never been rejected. In fact, he’s the one who has been doing all the rejecting so far. From rejecting stupid extras who tried to get in his damn pants to rejecting student heroes and fresh graduates who applied to his hero agency, Katsuki has no qualms rejecting them at all. In his entire 25 years of living, Katsuki has never faced a fucking rejection.

And yet, Izuku has just rejected him.

“You just got flat-out rejected, Bakugou!” Kirishima Eijirou exclaims, and Katsuki feels the urge to blast his stupid, laughing head off.

“Huh?” Izuku blurts out, and Katsuki can hear the confusion in his voice.

“Midoriya, dude! Just now, he was inviting you to join his agency!” Eijirou explains, and Katsuki wonders just how the hell did his - yes, his - nerd became a teacher when he can’t even figure out what Katsuki was trying to say. Pretty sure he made it clear too because he knows how fucking oblivious his nerd is.

“Oh?! Really? I’m good,” Izuku replies, his voice calm and casual, and Katsuki feels like his heart just got stabbed for the second time in the span of minutes.

“You’re kinda oblivious about this stuff, eh, Midoriya?” Eijirou quips, and Katsuki glares at the shitty head to get him to shut the fuck up.

Katsuki is in love with Izuku. It took him having his heart blown out and dying to realise his fucking feelings for his nerd. It has been years, and his idiots all know that. That’s why the stupid shitty head has been so fucking obvious the entire ride, and yet his oblivious nerd still doesn’t get shit. Katsuki can be waving the gay flag with Izuku’s face in a fucking heart shape and Katsuki doubts his nerd will get it.

Fuck, he doesn’t need to feel like a fucking loser more than he already does.

“Gah, shut up! I get the picture already!” Katsuki growls as he tightens his hands around the steering wheel.

No, he doesn’t. Katsuki doesn’t fucking get the picture. He remembers how happy Izuku looked when All Might had given him the hero suit; he was there when Izuku took his first flight in years. Izuku was happy to be a hero again, so why doesn’t he want to join Katsuki’s agency?

But looking through the rearview mirror, Katsuki can’t even be mad at Izuku. Seeing how fucking cute his nerd looks as he’s squished in the backseat that Katsuki had customised just for him (because he’s worried about his safety - and it’s definitely not for fucking his nerd like how his idiots had said, although he did think about that scenario and jerked off to it), the anger and annoyance in his heart calm down a little.

How can he be mad at his sweet, beautiful Izuku again? How can Katsuki hurt Izuku again just because he doesn’t want to join his fucking agency? He wants his nerd back by his side again, but that doesn’t mean he’s going to disrespect his nerd’s choices. Besides, Izuku is oblivious to everything and everyone. Maybe, just maybe, Katsuki can say something to get him to realise something.

“I ain’t cut out to deliver this message, but… listen… open your damn eyes, and try thinking more of yourself. Or else you’re gonna miss what’s staring at you in the face,” Katsuki says, red eyes flicking to look at Izuku through the rearview mirror.

‘WHY THE FUCK IS HE SO FUCKING CUTE?!’ Katsuki groans in his head, biting back his grin because of how fucking cute Izuku looks in the backseat.

Gods, the money spent on this damn backseat totally paid off.

“Uh… wrong messenger for sure,” Izuku mutters, and Katsuki groans internally. How fucking clear does he have to be?! Fucking hell.

“When everyone’s special to you, then no one is basically,” Katsuki says as he tries to hint the special bond they have.

Katsuki knows how Izuku sees everyone as special. He knows because that’s just how good and kind his nerd’s heart is. However, Katsuki was the first person Izuku had truly seen special. Those green eyes had followed him since they were 3 years old, and they hadn’t left him since. There’s just no fucking way that Izuku doesn’t feel anything for him from the way he looks at him. He can see everyone as special, but their bond goes way beyond that. They’re meant to complete each other in every ways, and Katsuki needs Izuku to realise that and return to his side.

Silence falls between them, until Eijirou breaks it with his stupid question. “Why’d you opt for those crazy backseats anyhow?!”

‘You fucking know why!’ was on the tip of the tongue, but since Izuku’s there and he seems to be deep in thought (Katsuki hopes he’s thinking about what he has just said and realises how special Katsuki is in his heart), Katsuki just glares at the idiot to shut up.

They arrive at the restaurant where the class gathering is happening, and he looks over to Izuku, who is already looking at him. “I’ll go in first, Kacchan. I’ll reserve us a seat! I’ll get you cola!”

“Yeah, go ahead,” Katsuki says as nonchalantly as he can despite how his heart swells in his chest.

Izuku remembers his go-to drink when he cannot drink beer or sake because he has to send him (and the fucking idiots) home. It has become a routine for Katsuki to send Izuku home. From Izuku’s years in college till now, he makes it a must for him to send Izuku home. When he didn’t have his car yet, they took the subway and bus home together. And now, he just drives Izuku right up to his steps. No matter how fucking busy it gets, unless he got hurt during a villain attack, Katsuki always makes it a point to send Izuku home.

And of fucking course, when his idiots noticed this, they took the chance to hop in for a free ride home after every gathering. The annoying part was that they had asked him with Izuku around. Fucking cockblockers.

“You okay, Bakugou?” Eijirou’s voice snaps him out of his thoughts, frowning as he looks at the red haired guy.

“Yeah. Why the fuck wouldn’t I be?” Katsuki asks as he kills his car engine.

“Well, Midoriya just rejected you. I- I guess I was just worried that you’d be affected by that,” Eijirou says, rubbing the back of his head awkwardly as he looks at Katsuki.

“You don’t think I’d fucking give up, do you?” Katsuki asks, smirking as he looks at Eijirou, whose eyes widen as he looks at him. “I have never fucking given up in my entire fucking life. I killed that shitty ass villain with my chest open, and I got his hero suit settled despite all the problems we encountered. I got him to tell me whenever he needs a hero to train his class, and I—

‘…made sure none of those fucking extras in his college class even dared to ask him out after that one time they got him drunk,’ is something that no one needed to know. Katsuki grins as he remembers that night as if it had happened just yesterday.

Katsuki was already waiting for Izuku outside his nerd’s school gate, as he usually did ever since Izuku entered college, when he received a text message from his nerd that he was invited to go to a bonding session with his classmates.

‘What the fuck is a bonding session?!’ Katsuki wanted to reply, but since he was a good friend, he just shot a ‘Okay, I’ll pick you up later’ instead.

(Friend; a word that Katsuki absolutely hated when it came from Izuku. His nerd was so happy when Katsuki got close to him and spent a lot of time with him after the war that he told everyone he had Kacchan as his childhood friend again. But Katsuki wasn’t happy; he wanted more.)

Katsuki knew Izuku had the right to make more friends, but he didn’t trust any of those fucking extras. Those idiots probably approached him for his title of ‘The Boy Who Saved The World’ instead of Midoriya Izuku himself. No one knows Izuku the way Katsuki does, and no one ever will.

Following Izuku and his college classmates, Katsuki frowned when he saw one of the idiots keep bumping shoulders with Izuku. He clenched his fists tight, red eyes blazing with fury when he recognised the idiot as the one who kept glaring at him when Katsuki picked Izuku up. Sitting in the corner of the restaurant, he clenched his jaw tight and resisted the urge to storm over to Izuku when the same idiot put an arm around Izuku’s shoulder.

“Come on, drink a little more, Izuku! It’s our first first time hanging out together!” the idiot said, grinning as he pushed a glass of beer towards Izuku’s face.

“I- I am not a good drinker, Tsukasa-kun…” Katsuki watched Izuku say as he smiled wryly and moved back, and the blonde gritted his teeth.

“Come on, just one!” the bright blue haired idiot said, and Katsuki knew just what he needed to do when the guy forced the beer down Izuku’s throat.

‘Someone’s gonna lose their hands tonight.’

Katsuki wanted to grab Izuku and take him away from the assholes, but he couldn’t because of how people would recognise him as ‘Dynamight’. Despite just debuting as a pro hero months ago, he had already climbed high in the hero rankings due to his contributions during the war. But Katsuki didn’t care about his reputation; he didn’t give a shit about all these hero rankings.

The only reason he didn’t want anyone to recognise him was because of his plan.

Katsuki waited long enough to be sure that Izuku was drunk before he made his presence known. Those idiots looked shocked to see him, eyes wide as Katsuki carefully helped Izuku up and grabbed his bag.

“Ka- Kacchan! Whe- when *hic* when did you arrive?” Izuku asked, and Katsuki knew the nerd was drunk out of his mind from the way his words slurred and the dazed look in his eyes.

Looking at Izuku’s flushed red freckled cheeks and how he was gazing softly at him, Katsuki’s heart swelled in his chest. How the fuck did Izuku still looked so fucking beautiful and perfect despite being drunk out of his fucking mind?!

“I just arrived, nerd. Why the hell did you drink so much when you know you can’t fucking drink?” Katsuki asked Izuku, but he kept his red eyes fixed on the idiots in front of him.

“They made me *hic* drink! It’s our first *hic* gathering so I cannot disappoint them!” Izuku replied, grinning stupidly cute, and Katsuki wished these idiots were not here to see how fucking adorable Izuku looked.

‘If only I could fucking tear their eyes out.’

“I didn’t see you coming,” the Tsukasa guy said as he glared at Katsuki.

Oh, this guy had some nerve to confront Katsuki like this. The urge to smash the fucker’s face against the wooden table had Katsuki clenching his fist that was not on Izuku’s waist.

“Your eyes barely moved away from Izuku, so of fucking course you didn’t see me entering the place,” Katsuki said as he stared the idiot down. “Come on, Izuku. Let’s go home.”

Slinging back Izuku’s bag over his right shoulder, Katsuki turned to Izuku and picked his drunk nerd up bridal style. Surprised gasps erupted around the table, and he flashed his victorious, mean grin at the blue haired idiot before walking out.

But no, Katsuki’s not done.

He brought Izuku home to his apartment first, which was thankfully not that far from where the gathering had taken place earlier. He could have brought Izuku to his apartment which was three blocks away, but why would he when Izuku had always slept over at his place whenever they drank together?

After all, he had picked an apartment close to Izuku for this very reason; for Izuku to rely on him and let Katsuki take care of him.

Putting Izuku in his bed, Katsuki changed him out of his dirty clothes and put him in the t-shirt and shorts that Katsuki had prepared for him.

“Ka- Kacchan? Where am I?” Izuku mumbled, cracking a dazed eye open as he looked groggily at Katsuki who was wiping his down his neck with a warm towel.

“My apartment, nerd. You’re drunk, and you still have your thesis or shit to submit tomorrow. Go to sleep,” Katsuki said softly as he brushed Izuku’s bangs back, smiling gently when Izuku nodded sleepily and snuggled close to him.

Katsuki’s heart fluttered in his chest, and he would have gone to change into his own sleep clothes if he didn’t have an idiot to settle. Tucking the nerd into his blanket and kissing his forehead (something that he always did when Izuku was deep in his sleep), Katsuki turned around and pulled out his phone. He smirked when he realised where the blue haired fucker was. Katsuki had slipped his watch, which had an inbuilt tracker linked to his phone, inside the fucker’s bag when he grabbed Izuku’s bag. And looking at where the idiot was currently, Katsuki smirked even wider.

“Looks like fate is on my fucking side,” Katsuki muttered as he got up to change into an all black outfit.

(The same black outfit Katsuki wore when he followed Izuku around from a distance during UA; the same black outfit Izuku himself had picked for him because ‘Kacchan would look so cool in it!’. The same black outfit that Katsuki had more than a few pieces of just because he could.)

With his hood up and hiding his face, Katsuki observed the fucker from behind a wall. He watched how the fucker walked unsteadily up the long stretch of stairs, grinning at how there was no one else around him. The subway stations had always been quieter at night, especially in this district the blue haired fucker had alighted. Katsuki waited until the guy was two steps away from reaching the top, and then he ran into the fucker hard. A loud scream echoed in the silent subway exit, and he smirked deviously as he watched the guy roll down until he hit the ground floor. The fucker was barely conscious, but Katsuki’s not done.

No, not yet; he wanted the hands that touched Izuku destroyed.

Wearing his steel plate bottom black boots solely for this purpose, Katsuki smirked as he stomped on both of the fucker’s hands. The fucker howled in pain, and Katsuki made sure to hear a good, satisfying crunch before he stopped and fled. He could have done more, but he was still a hero. And since he wanted to be a hero that Izuku would be proud of and love, Katsuki called the ambulance for the guy.

Katsuki spent the entire morning the next day comforting Izuku as his sweet nerd felt bad upon hearing what happened to his classmate, or rather ex-classmate; the guy was in such a bad condition that he had to drop out of school. Izuku thought he should have been there to send his friend home, but Katsuki reminded him that his asshole of a friend had forced him to drink. So, it wasn’t his fault.

It was fate, and his payback for being an asshole.

And of course Izuku scolded him a little for being mean, but his nerd totally eased up after Katsuki comforted him and promised him a bowl of katsudon. He knew his nerd well enough to know that Izuku would totally feel better with a bowl of his home cooked katsudon, or his favourite pancakes.

Izuku’s other classmates still asked him to hang out with them every once in a while, but seeing how Katsuki was always waiting at the school gate for him, they eventually stopped asking.

And Katsuki, he almost never missed a chance to pick Izuku up.

“Oh wow, Bakugou…” Eijirou’s voice pulls Katsuki out of his reverie, instantly dropping the grin on his face as he looks at the redhead. “…that’s so manly! The way you love Midoriya is so amazing and manly! Keep chasing him, Bakugou! I’m very sure he’ll see it one day!”

“Tsk! Of fucking course, he will! I won’t stop until he knows how much I really love him,” Katsuki says, rolling his eyes when Eijirou gives him a thumbs up.

Katsuki has never given up in his entire fucking life. He always makes sure to get a perfect fucking victory. If he can destroy that old, creepy fuck with his chest open, he can definitely get Izuku to be his.

 

𝄃𝄃𝄂𝄂𝄀𝄁𝄃𝄂𝄂𝄃𝄃𝄃𝄂𝄂𝄀𝄁𝄃𝄂𝄂𝄃𝄃𝄃𝄂𝄂𝄀𝄁𝄃𝄂𝄂𝄃𝄃𝄃𝄂𝄂𝄀𝄁𝄃𝄂𝄂𝄃

 

When Katsuki gave that talk about ‘when everyone’s special to you, then no one is basically’ to Izuku, he expected his nerd to think about him. It never crossed his mind that he would think about fucking Round Cheeks! Especially since she hasn’t been in contact with him for the past eight fucking years!

Watching from inside his car, Katsuki grips his steering wheel tight with his red eyes fixed on the couple talking and smiling at each other. His entire being burns with pure rage and jealousy.

“You know you can just tell him about how you feel instead of watching him like a creepy stalker from a distance, right?” Kaminari Denki quips, and Katsuki considers throwing the idiot out of his car.

His idiots don’t know that Katsuki already knows all of Izuku’s schedule for both school and his occasional patrol duties. They don’t know that Katsuki had already volunteered for all the hero lessons for his nerd’s class; they have no idea that he had made sure that Izuku was scheduled to patrol on the same day and shift as him.

“I had been with him through his entire fucking college, and I had even given him the hero suit! How the fuck else should I show I fucking love him when his oblivious ass can never see it?!” Katsuki growls, clenching his jaws when he sees the couple do a dap up.

It seems friendly, but Katsuki still hates it.

With his eyes constantly on Izuku, Katsuki noticed when his nerd’s green eyes shifted to someone across the room during the gathering earlier. He knew who Izuku was looking at, and it made him feel like dragging his nerd out. It made Katsuki feel like kissing Izuku stupid in front of everyone there, but he couldn’t.

He couldn’t because he might scare Izuku away.

He couldn’t because he might destroy whatever that they have now.

He couldn’t because Izuku isn’t his. Yet.

Despite how those beautiful green eyes weren’t looking at Ochako the way they looked at him, Katsuki still didn’t like how those eyes dared to drift away from him and look at someone else. Jealousy burned through his veins, and Katsuki felt like gripping Izuku’s chin to force him to look back at him; to have his green eyes only on him. A villain attack snapped whatever Izuku was thinking off as he looked at the female hero, and Katsuki silently thanked the villain for choosing that moment to attack.

“You know, you should have just insisted on waiting for Midoriya if you know you’re gonna be so bothered about him meeting up with Uraraka,” Sero Hanta says, raising his hands up when Katsuki throws him a glare.

Katsuki knows he should have, but he has to pick up Edgeshot who literally almost died saving him during the war. Besides, he didn’t know Izuku was going to meet Ochako. If he had known, there’s no fucking way Katsuki would have allowed him to meet the female hero without him by his side.

“I know it’s normal to feel jealous when you love someone, but there’s really nothing to worry about, Bakugou. They’re just friends,” Ashido Mina says as she pats Katsuki’s shoulder.

“I am just fucking friend too,” Katsuki growls through gritted teeth.

“I know! But it’s different! It’s really impos—” Mina was saying, but she stops when Denki nudges her with a look Katsuki doesn’t understand.

“What’s different? What the fuck are you saying?!” Katsuki asks, but the pink haired Pro Hero simply shakes her head.

“It- it’s okay, Bakugou! You’ll understand it when you know about it! I- it’s not my place to tell,” Mina says as she smiles wryly, and Katsuki swears he’s going to blast one of his idiots tonight.

“Come on, let’s just go off first, Bakugou. We can think of ways to make Midoriya see your feelings for him later,” Eijirou says, but Katsuki doesn’t want to leave yet.

He doesn’t want to leave Izuku alone with Ochako.

“You know, what if you try to make him realise his feelings for you instead?” Hanta asks, and Katsuki turns to look at the black haired Pro Hero.

“Okay. Elaborate,” Katsuki says, and he’s all ears.

“I personally think Midoriya likes you too, Bakugou. It’s obvious in the way he looks at you. But maybe, like you said, he’s too oblivious about his feelings. So, instead of doing more things to get him to notice your feelings, why not try to get him to notice his feelings?” Hanta explains, and Katsuki feels like he has just seen the light into a new religion or something.

Because really, WHY THE HELL DIDN’T HE THINK OF THAT?! Katsuki knows Izuku loves him, so why didn’t he think about getting Izuku to see his feelings for him?! To think that this suggestion comes from one of his friends who barely passed their final exams hurts his fucking pride.

“That’s a good fucking idea! But what do I do? How do I get an oblivious ass nerd see his feelings for me when I have been around him for the past eight years and he still doesn’t see shit?” Katsuki asks, frowning as he looks back at Hanta who shrugs.

“That I don’t know, man. I’m just throwing the suggestion out, but I don’t have any idea,” Hanta replies.

“Maybe you can make him jealous? They say jealousy shows a person’s true feelings for you. If you interact with some other good looking Pro Heroes, it might make him jealous and he would realise his—

“I am not gonna do shit that hurts him, Dunce Face!” Katsuki growls as he glares at the yellow haired Pro Hero.

“But you’re not really hurting him! You can step in and confess before he gets the wrong—

“I said no. I’ll never do a single shit that will hurt him again. One more stupid idea and ‘m blasting your stupid ass out of the car,” Katsuki threatens, and the other blonde Pro Hero immediately nods as he shrinks back into his seat.

Yes, Katsuki wants Izuku to notice his feelings for him, but he will never fucking hurt Izuku. No, never again. Besides, knowing his nerd all too well, Katsuki knows Izuku would not confess his feelings if he sees Katsuki with some other extras. His stupid, oblivious nerd would simply think Katsuki found someone else, and this might cause them to drift apart.

So, no, he’s not doing this jealousy shit.

There has to be some other way. Katsuki cannot think clearly right now; his brain is only thinking of ways to hurt and destroy Ochako. He knows that the female Pro Hero is a good person and a good friend, but she is still his biggest rival when it comes to Izuku. Katsuki knows about her feelings for Izuku when they were first years in UA, but he hadn’t realised his feelings for Izuku then. Now, they’re both fighting for Izuku, and he will fucking win.

Izuku will become his.

 

𝄃𝄃𝄂𝄂𝄀𝄁𝄃𝄂𝄂𝄃𝄃𝄃𝄂𝄂𝄀𝄁𝄃𝄂𝄂𝄃𝄃𝄃𝄂𝄂𝄀𝄁𝄃𝄂𝄂𝄃𝄃𝄃𝄂𝄂𝄀𝄁𝄃𝄂𝄂𝄃

 

Katsuki’s red eyes widen slightly, pleasantly surprised when Izuku dashed into his ward looking all frantic as he checked on him. “Kacchan! I- I heard what happened! Are you okay?! Have the doctors given you a full checkup?! Where are they?! I wanna speak with them!”

The thing is, he knows his nerd would come; Izuku had always come to see him when he was injured during patrols or villain attacks during his days in college. But he hadn’t expected him to come during his supposedly teaching hours. After all, Izuku had rejected Katsuki’s proposal because he wanted to focus on teaching. It made Katsuki feel that Izuku values those annoying, snot blowing brats more than him. But now, he knows; Katsuki is more important than teaching and those brats.

And Katsuki didn’t expect it. He didn’t even plan for this.

It had been just two days after Izuku had rejected his proposal to join his agency and seeing Izuku with Ochako, when he was called in for a villain attack at Musutafu mall. The villain wasn’t strong, and his quirk was mid at best, but Katsuki’s head was not in the fucking battle. Getting Izuku was all he could think of, and he didn’t notice the villain had sneaked an illegal quirk strengthening gun out.

“DYNAMIGHT! WATCH OUT!” was the last thing the top five Pro Hero heard before he felt a strong, sharp force throwing him forward, crashing face first into the wall.

“Fuck!” Katsuki growled as he spit out the blood pooling in his mouth.

Standing up on his feet, he realised that he was okay. Other than the slight pain in his chest, there didn’t seem to be any major injuries. He finished the fight, blasting the fucker with his howitzer impact and knocking him out cold. Except for some minor skin injury, Katsuki knew he was fine, which was why he had been so pissed when Best Jeanist insisted on getting him checked at the hospital.

Katsuki had been so pissed that some mid shit villain managed to even do a scratch on him, but the anger instantly went away when Izuku rushed into his ward in the hospital with pure worry and concern on his face.

“Kacchan! Why are you not answering me?! Are you in pain?!” Izuku’s voice snaps Katsuki out of his pleasant surprise, and it takes him everything to not smile at how worried Izuku sounded.

“I’m fucking fine, nerd. Just a little bruise on my chest and back. Other—

“Your chest?! You got hurt on your chest?! But you know your heart wouldn’t be able to take any strong impacts on your chest, Kacchan! Has the doctor checked you?!” Izuku asks worriedly as his hands roam all over Katsuki’s chest frantically to check on his wounds, and Katsuki grips the bedsheet tight so that he doesn’t grab the dainty wrists in front of him and pull his nerd down into the deep kiss he has been dreaming of.

“‘M fine, Izuku. The doctor checked me and confirmed that I only suffered skin injuries. They’re holding me back for one night to wait for the other test results,” Katsuki answers, red eyes watching how Izuku literally sighs in relief upon hearing his answer. And then, he throws out the question that he really wants to know the answer to. “But you, what the hell are you doing here? I thought you’re supposed to be teaching right now?”

“I was, but I heard what happened from the news and immediately rushed here. I was so worried, Kacchan! I watched the fight, and you were fighting so well until you looked like you lost focus. Were you quirked or were you already injured off camera? I was so so worried because it wasn’t like you to lose focus during a fight,” Izuku rambles on and on, and all Katsuki hears is the sweet song of victory.

Victory because Izuku is so worried that he abandoned his class for him.

Victory because Izuku’s beautiful green eyes are on him again.

Victory because he finally found a way that will get him Izuku.

Katsuki didn’t plan this, but he finally thought of the perfect plan to get Izuku to realise his feelings for Katsuki and get his nerd to be forever his. He will never hurt Izuku again, but it doesn’t count if Izuku gets hurt by worrying over him, right? It’s a good plan, and Katsuki knows it will work. It’ll take a little toll on his body, but what’s a little pain if gets to have Izuku? After all, he died for Izuku before. This is nothing compared to what he has done.

For Izuku, Katsuki can do anything and everything.

 

𝄃𝄃𝄂𝄂𝄀𝄁𝄃𝄂𝄂𝄃𝄃𝄃𝄂𝄂𝄀𝄁𝄃𝄂𝄂𝄃𝄃𝄃𝄂𝄂𝄀𝄁𝄃𝄂𝄂𝄃𝄃𝄃𝄂𝄂𝄀𝄁𝄃𝄂𝄂𝄃

 

Katsuki knows he needs to plan this well. He isn’t the number four Pro Hero for just his quirk. He has always been sharp and good at planning the next move during missions and battles, and he always makes sure that he wins.

Keeping his red eyes focused on the streets, Katsuki plans on his next move. He knows his quirk is strong, but that doesn’t mean he doesn’t get hurt. It’s part of a Pro Hero’s daily life to get hurt, and that’s what Katsuki’s counting on, but that doesn’t mean he can just get hurt. He has built his reputation on being one of the best Pro Heroes, so he cannot just get hurt; he needs to plan how to get hurt so that it doesn’t look suspicious.

Seeing how he had been cleared to get back on his patrols after a week of rest, Katsuki can either get hurt on this patrol and blame his stupid heart for acting up, or he can choose some other time to get hurt. But seeing how the former might cause him to be fucking stuck in the hospital, Katsuki decides on the latter; he needs to be able to do hero work to carry out his plans.

Katsuki needs to wait, but what’s a little more wait when Katsuki has waited eight years?

 

𝄃𝄃𝄂𝄂𝄀𝄁𝄃𝄂𝄂𝄃𝄃𝄃𝄂𝄂𝄀𝄁𝄃𝄂𝄂𝄃𝄃𝄃𝄂𝄂𝄀𝄁𝄃𝄂𝄂𝄃𝄃𝄃𝄂𝄂𝄀𝄁𝄃𝄂𝄂𝄃

 

“Kacchan!” Katsuki bites back the grin when he hears Izuku’s voice. “How did you get hurt again?! It’s not even one month since your last injury, Kacchan!”

“‘S not my fucking fault! The fucker crept up behind me!” Katsuki growls in fake annoyance, watching with glee as those beautiful green eyes he loves look at him worriedly from a lie he had come up with.

The villain was nothing to him. In fact, it was even weaker than the one that had caused him to be in the hospital three weeks ago. But there hadn’t been any villains causing trouble the past few weeks, and Katsuki was afraid there wouldn’t be any better chances than now. And so, he purposely missed his first AP shot, and waited for the idiot to sneak up on him. It went well, obviously. The idiot did exactly what Katsuki wanted, breaking his right arm with his breaking quirk before getting knocked down by Eijirou.

And now, Katsuki has Izuku worrying his beautiful head over him.

“I know it’s not your fault, Kacchan! Kacchan always does your best, so of course it’s not your fault!” Izuku says, his voice a tone higher as it always does whenever he praises his Kacchan, and Katsuki watches how those beautiful green eyes well up with tears as they fall on Katsuki’s bandaged arms. “It- it’s just… the villain broke your right arm, Kacchan. I- you worked so hard to get your arm to be okay again after the war, and now it’s broken again.”

Izuku has always been a crybaby, but to see Izuku crying for him, it stirs something in Katsuki’s gut; he wants to see Izuku’s beautiful, teary green eyes looking up at him while he stuffs Izuku’s sweet hole full. His dick twitches in his pants underneath the hospital blanket from the delicious image his always-horny-for-Izuku brain conjures, and heart races fast and loud in his chest. Before he realises what he is doing, he holds out his other hand to Izuku. Panic seeps fast into his heart when he thinks about the time he had rejected Izuku’s hand at the river, and he is just about to pull back his hand when Izuku grabs it.

Izuku actually accepted his hand. Holy shit.

Doing his very best to act cool about it, Katsuki pulls Izuku to sit by his side. “I know you’re worried, but ‘m really fine, Izuku. I promise, despite this stupid bandage, it isn’t as bad as it looks. The doctor even said that I can be back on the job after a few weeks of rest.”

“Are- are you sure, Kacchan? It- it won’t affect your arm when you use your quirk in the future? You- you won’t be in pain?” Izuku asks, his voice soft as he looks worriedly at Katsuki.

“Yes, ‘m fucking sure, nerd. You know the medical field has improved a lot over the past years, so they can fix simple broken arm like this without an issue,” Katsuki answers, watching how there’s still a slight frown on Izuku’s face.

The frown on his nerd’s face shows that he’s still worried, and Katsuki almost breaks out into a delighted grin at the thought that Izuku is this concerned about him. He eyes the warm, beautifully scarred hand in his grip, and his heart races at the fact that Izuku is still holding onto his hand. He had never noticed how small Izuku’s hands are. They’re small and dainty, and fits perfectly with his.

Even their hands are perfect for each other.

“Uh, how long will you be in the hospital, Kacchan?” Izuku asks, pulling his attention away from their hands.

“Three more days? But ‘m gonna tell them to discharge me early. There’s no fucking way ‘m gonna waste my time here,” Katsuki says, biting back a grin when the nerd frowns and shakes his head.

“What?! No! No, you cannot discharge early, Kacchan! You just have your arm broken! You need to rest well until the doctors discharge you! Please listen to me and don’t ask them to discharge you early,” Izuku says, panic obvious in his voice as he pleads to Katsuki to stay in the hospital.

And since Izuku has asked oh so nicely, how can Katsuki refuse? Especially when this gives him the chance to start the next step in his plan.

“Tsk! Fucking fine,” Katsuki replies, and he watches how Izuku’s face breaks into a relieved smile as he thanks Katsuki for listening to him. “Anyway, can you call Shitty Head or Tape Face down for me? I need one of them to get me something from my apartment.”

“Oh? I- if you don’t mind, I can help you get the things you need, Kacchan,” Izuku says softly, and Katsuki grins. Bingo!

“Some clothes and my unfinished reports that I need to submit this week. But ‘s not just that, nerd. I wanna ask them if either of them can crash with me while ‘m recovering. The doctor said I shouldn’t move my arm too much, so I’ll definitely need some help around the house,” Katsuki says, another lie because his arm is already more than good enough to move without any help.

The broken bones in his arms are already fixed. Katsuki was given three weeks of hospitalisation leave for him to not to use his quirk during this time so that his bones could heal to their prior state. And of fucking course Katsuki’s going to use this chance to get Izuku to move in with him. He had already planned this when he first learned of the villain’s quirk.

“You- can- can I help you, Kacchan?” Izuku asks, and Katsuki mentally cheers to himself. Another bingo! “I know you’re probably more comfortable if they’re the ones to help you, but I wanna help you too! I- I stay closer to you, so it’s easier for me to take my things! And- and they’re busy with their partners—

“Yes, nerd, you can help me,” Katsuki says, biting back another grin that almost slips on face when he sees Izuku’s green eyes widen in surprise at his reply.

“You- you’re letting me to help you? Really, Kacchan? You- I thought you wanted them to help you because you’d be more comfortable with them—

“The fuck you talking about? The only reason I wanted to ask them is that I know you’d be busy with your brats and school, Izuku,” Katsuki explains, and he can’t help if he’s frowning at his beloved idiot because how the hell can he think that Katsuki’s more comfortable with the other idiots when he has spent all his available time with his nerd?

“O- Oh? I- I always thought… you know what, never mind! I’m so happy that you let me help you, Kacchan! Let me message Aizawa-sensei and inform him that I’ll be taking a day off on the day you’ll be discharged! And oh! I need to see your doctors and ask them about your injury!” Katsuki watches as the nerd rambles cutely with a phone in his hand, and he smiles.

Everything is going as he had planned. Now that he has gotten Izuku to move into his apartment, it’s time for the next step: to get Izuku to stay.

 

𝄃𝄃𝄂𝄂𝄀𝄁𝄃𝄂𝄂𝄃𝄃𝄃𝄂𝄂𝄀𝄁𝄃𝄂𝄂𝄃𝄃𝄃𝄂𝄂𝄀𝄁𝄃𝄂𝄂𝄃𝄃𝄃𝄂𝄂𝄀𝄁𝄃𝄂𝄂𝄃

 

“Kacchan, you sit here while I settle your stuff for you,” Izuku says with a smile, and Katsuki nods as he watches his nerd carry their bags into his - soon, it’ll be theirs - room.

Seeing how Izuku walks around his house leisurely, knowing exactly where he keeps his things, it feels like the nerd belongs there.

And he does. Izuku does belong there with Katsuki.

“Kacchan, where- where do I put my stuff? And where should I sleep later? I know your spare room is your office, right? You know, I- I can just sleep on your so—

“You can just crash with me, nerd. ‘S not the first time we shared a bed anyway,” Katsuki hurriedly says, cutting Izuku before his nerd can even suggest sleeping on the sofa. There’s no fucking way he’s letting Izuku sleep on the sofa when his motive is to get his nerd in his bed forever.

Katsuki grins as Izuku’s freckled cheeks turn a light shade of pink, watching in amusement how the nerd nods slightly before scurrying into Katsuki’s room.

‘There’s no fucking way he doesn’t love me back’.

Katsuki watches as Izuku cooks for them in his kitchen. Wearing the apron that he had bought weeks ago when he planned this, along with his stupid t-shirt and fucking short shorts, Izuku looks so fucking cute and perfect that it takes all of Katsuki’s willpower to not walk up behind his nerd and hug the hell out of him.

‘Fucking him on the kitchen counter seems like a good fucking idea too,’ Katsuki thinks, biting his lip as he looks at the thick, luscious ass in those shorts.

Shifting his half-chub dick in his pants, he smirks when a new idea strikes him. One of his hands is broken now, right? So, it’s only normal for him to ask for help when he needs to use the toilet, right? And knowing Izuku, he can never say ‘no’ to his Kacchan. Grinning, Katsuki turns to look at his nerd.

“Nerd! I need your help,” Katsuki calls from the sofa, pulling back his grin and putting on his usual, indifferent face when he hears Izuku’s footsteps rushing towards him.

“Yes, Kacchan?” Izuku asks the moment he stands before Katsuki, but damn, Katsuki cannot pull his eyes away from how fucking delicious Izuku looks right now.

With how his fucking short shorts are hidden underneath the apron and how his face is slightly flushed from the heat of cooking, Izuku looks so fucking good that it has Katsuki’s dick twitching in his pants. The urge to just grab Izuku down and fuck him hard on the sofa claws from inside him.

“Kacchan?” Izuku’s voice snaps Katsuki out of his mind, and he forces himself to focus on his initial plan.

Katsuki pushes the hungry beast back down to the pit of his stomach. As much as he wants to fuck Izuku, he wants his nerd to recognise his feelings first. He’s not going to do shit that will destroy whatever they have now.

“I need the toilet, and I can’t do shit with just one hand,” Katsuki says, faking a frown as he looks at Izuku.

“Th- the toilet? You- you want me to help you… with going to the toilet?” Izuku asks, green eyes wide, and Katsuki nearly breaks into a grin from how red his nerd’s face looks.

“Yes, nerd. I need to pee, but I can’t fucking do it with just one hand,” Katsuki replies, biting his cheeks to stop himself from grinning when Izuku nods.

Walking next to his nerd as they head to the toilet, Katsuki’s heart thuds fast and loud in his chest. He’s about to ask Izuku to do the craziest shit, and he just knows the nerd’s going to agree with him. After all, Katsuki is Izuku’s soft spot. He has always been Izuku’s weakness. It’s so fucking obvious that even the villains knew that. And it made him wonder how the hell the person whose soft spot is him doesn’t even know he’s in love with Katsuki. His stupid, cute, perfect oblivious nerd.

Standing in front of the toilet bowl, Katsuki turns to Izuku. “Help me take off my pants, nerd.”

“T- t- take off your pants?!” Izuku stutters, green eyes wide while his face turns even redder as he looks at Katsuki and then down at his said pants.

“Yes, nerd, take off my pants. I need to pee and I can’t fucking take them off with one hand. Fuck, I can’t even move the other hand without feeling pain,” Katsuki lies, smooth as butter, and he watches as Izuku frowns while looking at his bandaged arm.

“I- I’m so sorry, Kacchan. I- I didn’t know you can’t even move them. Come, let me help you,” Izuku says, guilt obvious in his voice as he steps closer to Katsuki.

And Katsuki cheers mentally. He fucking knows his Izuku can never see or hear about him being in pain. And now, he’s about to have his dick in Izuku’s hands.

Katsuki hisses a little when Izuku releases his half erected dick, biting back a groan when Izuku’s warm breath hits his dick as the nerd bends closer to pull both his pants and boxers further down his thighs. His dick visibly twitches, biting back a smirk when he sees Izuku’s green eyes staring at it.

“Can you hold it for me, Izuku?” Katsuki asks, his voice a tone softer as he gazes at the smaller guy, whose eyes widen upon hearing his request.

“W- what? Hold- hold what, Kacchan?”

“Hold my dick, nerd. I can’t pee with my dick like this, can I? My other hand is holding onto my t-shirt, and I can’t use my useless broken arm,” Katsuki says, purposely emphasising on his ‘useless broken’ arm to get Izuku’s pity for him.

And as he had already known, Izuku agrees.

“O- okay, Kacchan…” Izuku whispers as he nods shyly, and butterflies literally erupt in the pit of Katsuki’s stomach when Izuku’s very warm hands touch his throbbing dick.

He knows he’s more than average size, but damn his dick looks fucking huge in Izuku’s trembling hands. He swallows down a lump in his throat, struggling to keep his composure when all he can think about is how Izuku’s hands are so fucking perfect for handjobs. No, scratch that. Everything about Izuku is fucking perfect for his dick.

“Ka- Kacchan?” Izuku’s soft voice reminds him that he has yet to pee, and so he does.

He tries to concentrate on peeing, but all he can think about is how to prolong this time so that he can still have Izuku’s warm hands on his dick. He’d prefer to have Izuku’s mouth and asshole, but he’ll take whatever he can now. His dick twitches when it’s done, and Katsuki hisses when Izuku wipes his dick. He can feel his face burns, but it isn’t from embarrassment. It’s from arousal; Katsuki wants to fuck Izuku so fucking bad.

“I felt a trickle down my balls, nerd,” Katsuki lies, and he watches how Izuku nods silently as he reaches to wipe his balls.

‘Oh, fuck! Shit, his hands are so fucking warm! Fuck, I really wanna fuck him!’

Once Izuku’s done with all the wiping, he quickly puts Katsuki’s boxers and pants on for him before stumbling two steps back. “I- I- I need to get back to cooking our dinner!”

Katsuki watches as Izuku rushes out, smirking when he walks out to see the nerd fanning his face. His worry that this might be too much instantly vanishes when he sees the way the nerd’s blazing red face, and the small smile on his lips as he looks at his hands.

‘Yeah, the nerd definitely loves me.’

Three weeks passed very fast, and Katsuki hates how Izuku’s already planning to go back to his apartment in two days. He cannot trick Izuku into staying longer when he’s going back to work soon. He’s planning to get himself injured again, but it’s hard when there are no crazy villains on a rampage lately. Katsuki is thinking when Izuku comes home with a huge bouquet of fucking red roses.

“What the fuck?” slips out of his mouth, red eyes blazing with a burning fury as they look at the roses in Izuku’s arms.

“Uh, someone- someone gives me,” Izuku says as he sets them down on the dining table, and Katsuki feels the urge to fucking blast it with his quirk.

“I see. Who’s that someone, Izuku? Round face?” Katsuki asks, and he can’t help the growl in his voice as he glares at the fucking roses.

He is pissed. Katsuki is fucking pissed that someone dares to give his nerd fucking roses. Katsuki thought he had already successfully pushed every block out his way of getting Izuku throughout the weeks Izuku stayed with him.

Katsuki was just watching some old All Might movies - the ones he knew Izuku loved - when his cellphone rang. He smiled like an idiot in love (he knew he was an idiot in love) when he saw Izuku’s name on the screen.

“Hi, Kacchan! What are you doing?” Izuku asked the moment Katsuki answered the call.

“Nothing much. Just watching some All Might movies,” Katsuki replied, grinning when he heard the huff from the other line.

“You’re watching All Might movies without me?! That’s so mean!” Izuku said, and Katsuki could see the cute ass pout on his nerd’s face.

“Who asked you to stay back late in school? You know damn well ‘m fucking bored here. I can’t do shit with my useless arm like this,” Katsuki said, smirking when he heard the papers stop shuffling in the background.

He knew how it would affect Izuku whenever he brought up his ‘useless, broken’ arm. And knowing that his arm would ‘recover’ soon, he’d be milking this shit for as long as he could.

And then, Katsuki would break something else to get Izuku’s attention.

“You know, I need to stay back because the students are having their exams soon, Kacchan. But I’m done! I’ll be home soon!” Izuku said, and that reminded him of why Izuku had called him in the first place.

Something told him that it was not to tell him he was coming home soon. “Why did you call me, nerd? Did something happen?”

“O- oh! No- nothing! Iida, Uraraka and Asui-chan invited me to dinner, but it’s fine! It- it’s just dinner! I’ll go with them another day! I’ll be coming home now, Kacchan! I’ll get your favourite chips so that you can have them while we watch All Might movies!” Izuku said excitedly, and Katsuki grinned.

Izuku chose him over them.

It wasn’t even a week later when Izuku texted him that his colleagues had invited him out for a group dinner.

[Go ahead. I’ll be fine. My arm is hurting a little, but I won’t fucking die from it. I already took my medicine. Go and enjoy your dinner.] Katsuki replied, and he smirked deviously.

Katsuki knew how the word ‘die’ or ‘death’ would trigger Izuku’s trauma from the war, especially when it came from him. He had died for Izuku, and his nerd knew it. It was mean, but all is fair in love and war, right? And Katsuki would do anything, even using a little bit of Izuku’s trauma, to have him.

And as Katsuki knew would happen, Izuku called him, his voice all worried and panic ridden. “Why is your arm hurting again, Kacchan?! Wait for me, okay! I’m coming home now! I’ll bring you to the hospital if it still hurts by the time I reach home!”

“Okay, Izuku,” Katsuki replied with his fake soft, pained voice.

Smirking, he ended the call. Izuku chose him, again.

Katsuki kept up with his antics and reasoning, grinning victoriously when Izuku chose him each and every time. Not once had Izuku pushed to go to the dinner or hangout; not once had Izuku chosen someone else over him. Izuku dropped everything and everyone for him, and Katsuki basked in the nerd’s love and affection for him.

It had always, and will always be his Kacchan over everyone else.

Katsuki had managed to make Izuku come straight home from work for him; he had managed to make Izuku choose him over every invitation to dinner and hangouts.

But it looks like he missed out one fucker.

“Wh- what?! No! No, Kacchan! Why- why would she give me flowers? This- this isn’t from her,” Izuku says hurriedly, but that doesn’t answer who the fuck the roses are from.

He needs to know who this fucker is.

“If it’s not her, who the fuck is it from?” Katsuki asks as he glares sharply at Izuku, who takes a step back from how Katsuki is crowding over him.

“Just- just a colleague, Kacchan. I- he invited me out to dinner tonight, but I had already rejected him! He- he insisted on giving me the flowers, so I- I had no choice but to accept them,” Izuku explains, but that doesn’t make Katsuki feel any fucking better.

He needs a fucking name.

“Who, Izuku?” Katsuki asks, keeping his eyes fixed on Izuku’s.

“Masahiro. Masahiro Kazuya,” Izuku answers, his voice soft and filled with worry as he looks at Katsuki. “Are- are you angry, Kacchan?”

‘Of fucking course, ‘m angry,’ is what he wanted to say, but he cannot because he doesn’t have the fucking right to be. Besides, Katsuki isn’t angry at Izuku. He can never be angry at Izuku. The raging fury burning in his veins is meant for the fucker who gave Izuku the disgusting flowers. Taking a deep breath, Katsuki forces a small smile as he ruffles Izuku’s hair. “Nah, ‘m just surprised cause you didn’t tell me someone was fucking hitting on you.”

Izuku’s face blushes beet red as he shakes his head vigorously, denying the fact that he had been flirted with. As if the fucking roses aren’t enough proof as it is. “I- I didn’t know, Kacchan! I- I thought he was just being friendly! I swear I really never expected him to like me that way!”

Of fucking course his sweet, oblivious Izuku didn’t know.

“Tsk. Someone could fucking die for you and you’d still not know that person loves you, of fucking course you wouldn’t know someone is hitting on you,” Katsuki says, and he watches how Izuku’s eyes widen at his words.

Did Izuku finally get it? It seems like he wanted to say something, his mouth opening and closing, but he ends up just excusing himself. And Katsuki’s left there wondering if Izuku finally understands how he feels about him.

That, and how to deal with this Masahiro shit guy.

Katsuki’s first instinct is to fully push him out of Izuku’s life. But, that would only solve his problem temporarily. With Izuku’s beauty, cuteness, and brain, there will always be someone else who will try to take Izuku away from him. Katsuki still has Uraraka to deal with, and he cannot keep having new competitors. He has waited eight fucking years, he cannot risk losing Izuku to someone else.

Not that Katsuki will ever fucking lose, of course.

He just… wants Izuku. No, he desperately needs Izuku to be his forever. Katsuki needs to have Izuku now, and the latest villain incident report he received an hour ago will do the trick. It’s not dangerous, but it will seal Izuku’s fate with him… forever.

It’s an unfair move, borderline crazy, but all is fair in love and war. And in this war for Izuku’s heart, Katsuki will win.

“Deku-kun, don’t you think Bakugou’s behaving weirdly recently?” Uraraka Ochako asks her best friend, frowning slightly as she looks at him.

Ochako finally gets to have lunch with Deku after weeks of being pushed back and cancelled because Bakugou needs his help. She knows the blonde’s feelings for Deku; it’s clear as the sky is blue, but she doesn’t understand why he’s suddenly so clingy to Deku now. It wasn’t like this before, and it weirded her out a little.

Not that Bakugou and Deku’s relationship had ever been normal in the first place.

“Huh? What do you mean, Uraraka? I don’t see any weird behaviour from Kacchan at all,” Deku replies, frowning confusedly, and Ochako sighs.

“Of course, you don’t,” Ochako mutters. “I mean, don’t you think he’s been way too… how do I say this? Hmmm… don’t you think he’s been very attached to you lately? Like he needs your help all the time, and something always happens when we ask you out?” Ochako asks, smiling wryly.

“That’s because Kacchan’s hurt! You know he broke his arm during his patrol last month. So, of course he needs my help! Kacchan tries to do things himself, but there are limitations. So, I help him with… uh, you know, things that he can’t do,” Deku replies, and from the way his voice softens at the end and the way his cheeks turns scarlet red, Ochako knows she definitely doesn’t want to know what happened behind their closed doors.

And seeing how the blonde Pro Hero had glared at her like she killed his family whenever they crossed paths during patrols and meetings, Ochako knows it’s best for her to stay clear of these crazy gays. Sometimes, it makes her wonder why the hell these two idiots can’t just confess like normal people? At their age, it’s not hard to say ‘I love you’ and get on with life without bothering others with their love life.

And then she remembers it’s Bakugou and Deku she’s talking about, and it makes sense for them to be stupid for one another. One is crazy, obsessed in love while the other is obviously in love but is oblivious at the same time.

Yeah, she’s definitely going to stay clear of their stupid, messy love life.

Finding out from Denki that Izuku has lunch with Round Cheeks is the last fucking straw for Katsuki. He plans to do this in the coming week, but it looks like he needs to set his final plan in motion today so that he doesn’t fucking lose Izuku to fucking Round Cheeks.

“As you had suspected, the pervert villain is really making his move today, Dynamight. His last seen is three blocks away from where his last victim was found,” Katsuki nods as he listens to the information given via his earpiece. “You’re not that far from him, but seeing how his quirk activates just upon touching, I suggest for you to wait for Hero Deku, Dynamight.”

And that’s exactly what Katsuki is counting on. The villain’s quirk isn’t dangerous. It just has an aphrodisiac effect on the people he touches, using his quirk to get the people he touches to fuck him stupid. It’s how he makes people lose their minds to the effect of feeling all high and hot like a dog in heat, and Katsuki’s planning to use that effect to get Izuku to ‘help’ him.

“I’ll go first. I know Deku will reach me in no time,” Katsuki says, smirking as he ends the comm.

Katsuki spots the villain easily from the rooftop. The fucker doesn’t even make a fucking effort to hide, as if he is waiting to be captured. Or, he’s just one smug asshole who thinks he can run forever after escaping for the last three times.

Tsk, not on Katsuki’s fucking watch. Especially when he needs the asshole’s quirk.

“Kacchan! I’m reaching your location in three minutes!” Izuku’s voice rings through his earpiece, and Katsuki grins: it’s showtime!

He drops behind the villain, purposely surprising him with his presence so that the villain will notice him and prepare himself to use his quirk on Katsuki. The villain dashes into the crowd, touching everyone in his way to block Katsuki’s path. This might stop some rookie Pro Heroes, but this is Dynamight, and the top number four Pro Hero never loses his sight of a villain. Using his quirk to blast himself above the crowded area, Katsuki spots the villain and shoots him with his medium power AP shot - he wants to stop the villain, not knock him out. As everyone scurries to get away from the area, he smirks when he sees the villain squirming on the ground.

Seeing how the villain is activate his quirk, Katsuki quickly pounces on him and lets the fucker to activate his quirk on him. “Fuck!”

Katsuki stumbles back from the effect of heat rushing through his body, biting back a grin when he hears him. “KACCHAN!”

The pair of warm hands on his waist burn his body even more than it already does, causing him to lean against Izuku as he buries his face into Izuku’s neck. Gods, despite the greasy metal suit, Izuku smells so fucking good. “Fuck! It’s fucking burning me, Izuku!”

“You got quirked, Kacchan?!” Izuku exclaims, his green eyes widening with panic as he pushes Katsuki back to look at him.

“Y- yeah! I- I thought I fucking had him! Shit! Did- did he get away?! You should go after him, Izuku! Don’t let him fucking get away!” Katsuki exclaims, making his voice sound as pathetic as he can and faking a deep frown as he squirms in Izuku’s hold, acting like he’s in so much pain when the effect of the quirk is barely painful.

The quirk’s effect makes his body burn with a desire to fuck, not burn him alive like he’s acting right now. But Katsuki knows Izuku trusts him, and he’ll never ever doubt his Kacchan.

“It’s okay, Kacchan! Kirishima and Sero are already chasing after him! I’ll bring you to the hosp—

“I- I don’t need the hospital, Izuku. I- I don’t want to go to the hospital. The quirk isn’t dangerous, I can handle this on my own,” Katsuki growls, biting his lips as his dick throbs in his pants.

Shit, the quirk’s effect is increasing, and Katsuki really needs Izuku now.

“But- but you’re quirked, Kacchan! I- I need to get you checked and—

“I don’t need to get checked, Izuku. I- do you know what the villain’s quirk is?” Katsuki asks, his voice deep and raspy, one hand gripping tightly on Izuku’s waist over his metal suit.

Izuku doesn’t answer him. Instead, he just slowly helps Katsuki to the closest, deserted alley he can find. Katsuki presses his body flush to his nerd’s, feeling the way Izuku’s hands tighten around his waist when he presses his face into his nerd’s neck again.

“I- I heard about it, but I’m not sure, Kacchan. Just- just let me bring you—

“It’s pleasure by touch, Izuku. His quirk is gives an aphrodisiac effect on the people he touches, making their bodies burn until they fuck someone,” Katsuki explains, his dilated red eyes watching how Izuku’s face gradually turns redder and redder from hearing his response.

“Ap- aphrodisiac effects? S- so, Ka- Kacchan needs to have sex with someone to ease the effect of the quirk?” Izuku whispers, his voice breathy, and Katsuki bites back a grin from the way the nerd’s looking at him.

From the way Izuku’s staring at him, Katsuki can tell Izuku wants him too.

“Yes, and my body is fucking burning now, Izuku. I- it’s so fucking hot that it fucking hurts,” Katsuki whimpers, groaning low in Izuku’s ear. “Help me, Izuku. Can you fucking help me please?”

“B- but I- I don’t want to take advantage of Kacchan when Kacchan’s mind is not clear like this…” Izuku whispers, and Katsuki shakes his head.

It’s not a ‘no’; Katsuki knows his nerd wants him too, but it seems like Izuku needs a little push. “My body is fucking burning, but head is clear, Izuku. I don’t want to go to the fucking hospital, neither do I want anyone else. I want you to help me, Izuku. I’ve only ever fucking want you.”

“Y- you want me? What- what do you mean, Kacchan?” Izuku asks, and he has had enough of explaining with words. Katsuki crashes his mouth against Izuku’s.

Placing a hand on the back of Izuku’s head, he pushes his nerd back against the wall and kisses him even harder. It takes a few seconds for Izuku to respond, but he does; Izuku kisses him back. Wrapping his beautiful, scarred hands around Katsuki’s neck, the nerd kisses him back with as much fire and passion as Katsuki does.

Holy fucking shit, Katsuki is finally swapping spit with Izuku!

“Fuck, you have no idea how long I had been dying to do this to you, Izuku,” Katsuki whispers against Izuku’s lips, peppering kisses on Izuku’s lips because he hasn’t had enough of kissing him yet.

Fuck, he wants more. Katsuki wants so much more.

“Y- You have, Kacchan?” Izuku whispers as tears filled his beautiful green eyes, and Katsuki sighs at his fucking cute, oblivious nerd.

“Of fucking course, Izuku. My body moved on its own for the first time because of you; I fucking died for you. I started your hero suit because I wanted you back at my side, nerd. I- I thought I made it fucking clear, but you still don’t see how much I fucking love you,” Katsuki says, red eyes gazing softly at the nerd, whose lips are trembling as he holds back his tears.

“I- I thought you were just making things up to me, Kacchan. I- I really didn’t know… I- I had always loved you too, but I thought you deserved someone better. Someone that can protect you… Someone that you can keep chasing—

“There’s no one fucking better than you, Izuku! I only want to fucking chase you! I don’t want any other fucking extras! You hear me, baby?” Katsuki declares loud and clear, and he watches how Izuku blushes bright red from his confession.

“Y- Yes, Kacchan…” Izuku whispers, smiling when Katsuki kisses him again.

Katsuki kisses Izuku hard, grinning when Izuku opens his mouth. Biting his lips and sucking on his tongue, Katsuki groans into the kiss as he grinds his body against Izuku’s metal suit.

And damn, as much as he loves seeing Izuku in that suit, he needs Izuku’s metal suit off now.

Pushing Katsuki back slightly, Izuku looks around cautiously before looking back at him. “Kacchan, we’re in public. We should go back to your apartment to settle—

“We won’t make it to my apartment, Izuku. My entire body is fucking burning. I need your sweet hole now, baby,” Katsuki says, grabbing Izuku’s hand to rub against his very erected dick.

Izuku’s face burns redder from Katsuki rutting against his hand, but he doesn’t pull back. “O- okay, Kacchan. Your car is nearby, right? Let’s head to your car first.”

Katsuki doesn’t know how they reach his car. His entire brain is mush from the heat of the quirk’s effect, only realising he has reached his car when Izuku pushes him into the backseat. Sinking into his backseat, Katsuki realises he’s finally going to fuck Izuku.

And hell yeah, their first time will be in the fucking backseat he customised specially for Izuku. And thank fucking gods his forever-horny-for-Izuku brain had him to install tinted windows for his car. 

Katsuki grins when Izuku enters the car with his suit off, pulling his boyfriend - damn, he can finally call Izuku his fucking boyfriend now - down into another a deep kiss while touching him all over. He has dreamed of this moment for more times than he can count, and it’s finally coming true; he’s finally kissing and touching Izuku. Trailing his kisses and bites down Izuku’s neck, his hands busy themselves with taking off Izuku’s shirt. His dick throbs painfully in his pants, but he hasn’t had enough of kissing, licking and biting Izuku’s body.

“Ka- Kacchan…” Izuku moans when Katsuki bites on his nipple, hands squeezing on Katsuki’s shoulders as he arches back to let Katsuki have more of him.

“Fuck! How the hell do you taste so fucking good, baby?” Katsuki growls, wrapping his arms tight around Izuku’s waist as he leans up to seal Izuku’s lips again.

With their tongues dancing and swirling in the air between them, drool drips down the corners of their mouths. Katsuki licks up Izuku’s jawline, sucking bruises down his neck and collarbone to mark Izuku as his. He grinds up against his nerd, smirking when Izuku moans from the delicious frictions between their very erected dicks.

”Hnnn… Ka- Kacchan… Ahnnn…” Izuku moans into his ear when Katsuki bucks his hip up, fingernails digging into Katsuki’s shoulders as he grinds down to meet Katsuki’s pace. 

Katsuki has no regret getting himself quirked, but he just fucking wishes he had more time to kiss, lick, and bite Izuku all over without feeling like his balls are fucking bursting in his pants. The need to stuff Izuku full rages in him, but he doesn’t want to end the foreplay. He wants to satisfy Izuku more; he wants to taste every inch of his body.

“Kacchan, let me help you…” Izuku whispers, hot lips against his ear, and Katsuki nods hesitantly.

Leaning back against the backseat, he lifts his ass to allow Izuku to pull his pants off him. He hisses when Izuku pulls his boxers off; a low guttural growl slips his lips when Izuku holds his dick. Shifting to the side slightly, he throws his head back and moans when Izuku licks up his shaft. He looks down at Izuku, red eyes meeting green ones as Izuku continue to lick up Katsuki’s shaft and swirls his tongue over the tip of his dick.

“Fuck!” Katsuki curses, one hand slipping into Izuku’s hair when the nerd suddenly takes him full in his mouth.

Izuku’s mouth feels hotter than the blast of his quirk. The way Izuku swirls his tongue around the tip Katsuki’s dick, and how he manages to swallow him full makes him wonder if his nerd had ever done this to anyone else. He tightens his grip in Izuku’s hair from the sudden jealousy burning in his chest, easing his hold only when his eyes meet teary green ones.

Looking at those teary green eyes looking up at Katsuki with Katsuki’s dick full in his mouth, it’s an image he had seen countless times in his wet dreams; an ethereal image that his forever-horny-for-Izuku brain had come up with ever since he realised he was in love with Izuku.

And he realises he doesn’t care if Izuku has ever done this before. From now on, Izuku will only be doing this kind of shit with him.

Not wanting to be the only one who to be pleasured, Katsuki unbuttons Izuku’s pants with one hand and slips his hand in to feel Izuku’s thick, luscious ass. He finds the sweet hole he has been dreaming off since he was 18, smirking when Izuku moans on his dick when he shoves two fingers into his sweet hole. Seeing how tight and dry his nerd is, Katsuki pulls his hand back and grabs the lube that he had prepared. Katsuki goes back to fingering Izuku, scissoring and opening him up while his nerd moans on his dick while swallowing his dick deeper.

Fuck, he doesn’t expect his nerd to be this fucking good with his mouth.

“Fuck! Coming! ‘M fucking coming, baby!” Katsuki growls, pushing Izuku’s head down onto his dick as he comes down his nerd’s throat.

Katsuki comes hard, the kind that whites out his vision for a good few seconds, but he isn’t done; he’s still fucking hard. He pulls Izuku onto his lap and kisses him. He tastes himself on Izuku’s tongue, his heart flutters with happiness and joy that his Izuku had swallowed all of his come.

“Are- are you feeling better, Kacchan?” Izuku asks as he leans back to look at Katsuki, and he is feeling better.

But, Izuku doesn’t need to know that, does he? After all, he hasn’t fucked Izuku yet.

“No, baby. I still need more. My body still burns,” Katsuki lies, faking a frown as he tugs Izuku’s hair back behind his ears.

“Oh… okay, Kacchan. L- Let’s continue then,” Izuku whispers, and Katsuki doesn’t need to be told twice as he starts to kiss Izuku’s neck again. Damn, Izuku tastes especially good around his neck area. “Why- why do you keep calling me baby, Kacchan?”

“Why? Don’t you like it?” Katsuki asks, leaning back to look at Izuku, who immediately shakes his head.

“N- No, it- it’s not that. It- it just feels weird, but I like it! I really love it! I love anything that you call me, Kacchan!” Izuku says, and Katsuki grins.

“Good! You’re my boyfriend now, which means you’re my baby and every other fucking sweet names I can think of,” Katsuki replies as he leans up to seal Izuku’s lips into another open mouth kiss.

With one hand wrapped around his nerd’s waist, he struggles taking Izuku’s tight ass pants off. After a few tugs, Izuku leans back to take his pants off before climbing on Katsuki’s lap again.

“Kacchan…” Izuku moans when he feels the tip of Katsuki’s dick rubbing deliciously against his hole.

Katsuki aligns the tip of his dick to Izuku’s sweet hole, grunting when Izuku slowly lowers himself on Katsuki’s dick.

“Jesus, fuck! You’re so fucking tight, baby!” Katsuki groans, throwing his head back against the back seat while his hands grip tightly onto Izuku’s waist.

Biting on his lips, Katsuki groans from the heat and tightness of Izuku’s sweet hole. The way Izuku’s sweet ass pussy squeezes tightly around his virgin ass dick has him focusing hard to not fucking come when he hasn’t even entered fully into his nerd.

“Hnnn… Kacchan… Kacchan’s so big…” Izuku moans, fingernails digging deep into Katsuki’s shoulders as he continues to sink down on Katsuki’s dick.

“Yeah? You like it, baby?” Katsuki growls, smirking and leaning up to kiss Izuku again when his nerd nods shyly while sinking on his dick.

Fucking hell, how the hell is his beautiful Izuku still so innocently shy when he’s literally sinking on his Kacchan’s dick right now?

Fucking Izuku’s sweet hole is so much better than any wet dreams he has ever had. Katsuki feels his palms heating up from the pleasure of Izuku’s sweet hole squeezing around his dick, but it’s not enough to cause Izuku any pain. He gazes at Izuku, dilated red eyes meeting green ones as he thrusts up into Izuku.

“Ahn! Ahn! Ka-! Kacchan! Kacchan! Ahn!” 

“Fuck, baby! You feel so fucking good! Shit!”

The squelching sound of their fucking resonates in the car, and Katsuki’s fucking glad he had chosen to park in a private area reserved only for Pro Heroes, an area that he knows no one will be coming to unless an incident break out. They continue to kiss and fuck at the backseat of Katsuki’s Porsche, going at it for hours until Katsuki feels Izuku needs a short rest. He lies to Izuku that the quirk effect has subsides enough for him to bring his nerd home to his apartment, and then continuing in his bed.

Katsuki officially has Izuku has his boyfriend.

Katsuki makes sure everyone knows Izuku is his boyfriend.

Katsuki finally finds out what Mina means when she said Izuku and Round Cheeks are just friends. He doesn’t know how he didn’t know Round Cheeks is with Frogger, but he’s glad that settles; he no longer has an active rival for Izuku.

Not that it matters, because Izuku is finally his boyfriend.

And Katsuki works hard to make sure that Izuku will be more than his boyfriend in the future. He may seem less clingy than he was before officially getting Izuku, but he still makes sure that no one will ever get in between them. Anyone who even dares to ask Izuku out ends up getting ‘accidentally’ hurt, and Katsuki gets himself hurt every once in a while until Izuku finally gives in and agrees to join him at his agency.

It’s a cheap, dirty move, but all is fair in love and war. And Katsuki, he never fucking loses. Izuku is meant to be his, and they will together for the rest of their lives.
