Summary
     Izuku knew that if he couldn't end this fight soon, they were going
     to be in serious trouble.
Notes
See the end of the work for notes
They stood there, opposite of each other, panting. Sweat was dripping from
every part of their body and mingled with blood and highlighted bruises.
Neither was relenting from each other. Izuku realized that he wasn’t shaking
anymore. He was standing on his own against Bakugou. Those green eyes stared
down red. That flame of anger was unrelenting. Nothing was putting this fire
out.
At this rate we’ll exhaust each other or we’ll end up destroying something.
There was smoke and burn marks of explosions everywhere. There was already
evidence that there was a fight here. They were going to be in so much trouble
already. Adding destruction of school property to the list wasn’t something
Izuku wanted to add to his already incredibly long list of rules he’s broken
already. ‘He tolerated the kick at eight percent but with a three percent
increase he should at least-’ Izuku paused in his thoughts as he noticed red
trickled down the side of Bakugou’s neck. He was bleeding from the head. ‘As I
thought. It’s why he’s pausing. He’s not showing it but he’s hurting. I have to
end this. But there has to be the better way!’ He didn’t have time to think
because in that second he heard those familiar firecracker pops. Izuku moved
towards him. “Enough, Kacchan!”
“Shut the hell up Deku!” Bakugou replied as he aimed for another blast. It was
cut short. Izuku moved at the last minute and had grabbed him by the collar,
dragging him out of the main street and into one of the alleys. “What the hell
do you think you’re doing?! Fight me! Nngh!” He grunted as he felt Izuku slam
him against the wall, keeping him pinned with that fucking quirk. The other was
shaking. Bakugou could tell the other was thinking. But what of? “Dammit you
piece of shit let me -”
It happened too fast for even Bakugou to register. Looking back on it, it was a
kiss. A first for both. Sloppy. More teeth than anything. When Izuku pulled
back, Bakugou snarled. “What the hell are-” His mouth was covered by a hand.
Bakugou saw his chance to blow the other away but he froze.
“Shut up! Just shut up Kacc...Katsuki! You are...you are insufferable! I’ve
never done...anything to you but be a friend! You’ve always taken it the wrong
way...like the idiot you are!” Izuku cried out, pushing his rival against the
wall hard enough to make it crack a bit.
It snapped Bakugou back to his own focus and he blew Izuku off of him, making
the teen fly hard into the other wall. “Is that how it is, Deku?” He moved and
picked the other up, slamming him into the wall in turn, his hand on the
other’s neck. Smirking as he felt the other squirm, he tightened his grip. “And
what a dirty trick, kissing me like that? Is that how you’re going to win your
fights? Kissing them? Are you going to become the super wh-eh?” He felt Izuku’s
foot on his stomach and with incredible force he was sent back again. Before he
had time to get up, Izuku was on top of him and his mouth on his again. He felt
tongue and he growled, biting down on the invading flesh and that got Izuku to
back out. Bakugou wouldn’t admit that the sight above him made him go quiet for
a moment.
The look in Izuku’s eyes was nothing he had seen in their twelve years of
knowing each other. Confidence. Those greens were brimming with it. For once,
Bakugou was right. Right in this moment, Izuku Midoriya was looking down at
him.
“Finally got you to be quiet.” Izuku let out a sigh. “But we’re not done, are
we?” The tone was strangely calm. “You won’t be satisfied until one of us is on
the ground, unconscious. That’s how it is with you.”
“Tch!” Bakugou grunted and moved his hand only for it to be caught and laced
with Izuku’s own, glowing bright with One For All’s power. The shock more than
anything had caused Bakugou’s explosion to fizzle out.
“I have you pinned. Give it up, Kac-Katsuki. We’re going to be in enough
trouble as it is!” He hissed at him but it was his turn to be caught off guard.
Bakugou had him pinned now, his own mouth overwhelmed by the blonde’s. But
Izuku fought back, kissing him again and making him growl.
“Get back down!” Bakugou snarled at him, a knee going in between Izuku’s legs
and pressing hard. “As I thought. Fucking pervert.”
Izuku frowned and shifted his own legs to rub his own knee against him, making
his bully falter. He smirked. “Not the only one.” He managed to get out before
Bakugou kissed him again. Biting his lower lip and his tongue. It was
definitely heated. A battle of dominance, but Izuku was going to let Bakugou
have this one. It was part of his plan after all. A better way to expend their
energies. Izuku wasn’t going to be a punching bag anymore and this was the only
other way he could think of letting all of the frustrations out. Not that he
wasn’t going to struggle. It wouldn’t be good otherwise.
They pulled apart from their kiss, both panting, Bakugou snarling. “Fuck,
Deku.” He dove down and started biting and sucking at him.
“H-hey...don’t draw blood...are you listenin-hiiiiii!” Izuku whimpered as he
felt Bakugou’s teeth sink deep into his skin. “Hey!” He pulled at his hair and
yanked him off. “You’re not an animal! You can bite all you want, just don’t
draw blood!”
“You’re a damn pansy, Deku.” Katsuki licked his lips. “I wanna hear you cry
more.”
“You’re so messed up.” Izuku replied, his face dead serious.
“Yeah?” He asked, pinning his rival down again and rubbing his knee against his
crotch. “You fucking love it.” Bakugou chuckled and went down to bite at
Izuku’s neck once again. Impatient hands ran up Izuku’s shirt, feeling every
inch of him. Damn...I knew he got bigger when he got in to UA but this
is...fucking Deku. Doing this behind my back! He pulled back and pulled off
Izuku’s shirt to get a full look at him. He did this to get that power of his
didn’t he? With the rebounds he got at the start of the year in the shape that
he’s in...what the hell Deku? You really are fucking stupid!
“Ah! That hurts! That hurts Bakugou!” Izuku called out to him and Bakugou
blinked.
“Huh? What the fuck are you whining about now?!” He looked at him and smelled
burnt flesh. His hands had been burning Izuku’s hips. “Tch!” Bakugou pulled his
hands away and reached in his pants pocket, tossing a small bottle to Izuku.
“Stop bitching. Jeezus.”
Izuku looked at the bottle. Medicine to treat burns.
“Put some on moron! I ain’t got all night!” He barked at him, making the other
jump and then move quickly to apply the cream and setting it aside. “Finally.”
Bakugou moved and started attacking the rest of Izuku’s body, littering it with
bites and scratch marks. Izuku was squirming and whimpering and it only made
him harder. “Fuck…” Bakugou reached around and lifted Izuku in his lap, kissing
the other again. Claiming him. One hand held him up while the other focused on
undoing Izuku’s pants. Pulling the arousal free, he heard a noise he knew he
wanted to hear over and over again when he started to stroke him.
“Ah! K-Kacchan!”
“You like that nerd? Fuck you’re fucking squirming so nicely.” Bakugou chuckled
in Izuku’s ear, making him moan. “C’mon…” He sat back a bit, pulling the other
higher. “Touch me you lazy piece of shit. I’m not doing all the work.” He
commanded and he felt those fingers work at his pants and free him. His whole
body shuddered when Izuku’s hand started to stroke him. Red eyes looked down
and he noticed. Izuku’s right hand now. How messed up it was. When the hell did
he get that? Bakugou knew he didn’t cause that. It just made him more angry.
That this fucking moron messed himself up like that. “Don’t you dare stop.” It
was a warning as he stopped himself, reaching for that tube of medicine. “If
you fucking cry I’ll go back to kicking your ass.” Another warning as he coated
a finger with the cream and pulled Izuku’s pants down a little further, his
finger teasing him.
“No way in hell!” Izuku shouted, using his quirk to have the strength to pin
Bakugou down. “I’ll do it myself.”
“What? You don’t trust me? You’re fine when I’m jacking you off.” Bakugou
mocked, knowing exactly why Izuku wasn’t letting him finger him. He earned a
rather rare glare for his efforts. “Tch! Fine. Be a fucking pansy.” He huffed
as Izuku took the cream from him and pressed a finger into himself.
“Ah…” Izuku shivered, moving his legs so that they were on either side of
Bakugou, arm reaching back as his finger thrust into him. “Mnnn...ah…mn!” He
squealed, sending a shiver down Bakugou’s spine.
“H-holy hell Deku. Are you fucking serious?” He chuckled a bit even as a blush
formed on his face. Shit. If this is what he got instead of fighting Deku he
didn’t have too many complaints. The little nerd looked good like this. He saw
a second finger go in and felt Izuku shiver. “Hey!” Bakugou made him sit up a
little and grabbed his face. “Don’t you fucking come yet you got that?”
Izuku pulled his fingers out and gave him a very serious look. “Then make me,
Katsuki.”
Those words set off a completely different bomb inside of Bakugou and in a
matter of moments, he had Deku on his hands and knees, ass in the air. More of
that cream. Christ he was gonna get questions as to why he needed a new supply
so fucking soon but he’d make something up.
Now lubed in the best way he could be given the situation, Bakugou penetrated
Izuku, eliciting a cry of both pain and pleasure from him. “Fuck. You’re
fucking tight.” He growled, pinning Izuku’s face into the ground as he started
to thrust.
The other moaned. His tolerance for pain was a blessing in this moment as
Bakugou was not waiting at all. Not that Izuku wanted him too. It felt so good.
Too good! The current way they were going though...it would just stroke
Bakugou’s ego more. Grunting, he used his quirk again to lift himself up and
send Bakugou on his back. Izuku moved with him and turned so that he was facing
Bakugou. “Mnn...you think you’re in control?” Izuku moaned out as he started to
ride the other. “Oh god...Katsuki….” He moaned out, but saw that the other was
trying to sit up, probably thinking he was distracted. “No.” Izuku pinned him
down with his quirk. “No.” He panted out again, giving him a look that left
Bakugou speechless.
The blonde growled as he moved his hips while Izuku kept him pinned. That look
in his eyes. Another image Bakugou never saw before. He realized just what
Izuku did to him. I fucking get it. You aren’t doing this for yourself. You’ve
never done it for yourself. That irritating personality of yours. That’s what
All Might sees in you. You put everybody before yourself. Bakugou grunted,
moving faster and growling as Izuku moaned, calling out his name. “You’re a
real piece of shit, Deku.” He felt the other’s pressure on him lighten and he
sat up, pulling the other in for another rough kiss and wrapping his arms
around him. Nails dug into the back, making Izuku moan as he moved his hips
more. “Fuck…” He panted as he felt Izuku tighten around him.
“Kacchan...I hate you so much…” Izuku looked up at him before moaning.
“Not as much as I hate you.” He grunted in turn, holding on to those burnt hips
tightly as he thrusted harder, making Izuku cry out again and opening his neck
for more marks. “God I fucking hate you.” Bakugou pulled at Izuku’s hair as he
licked up his neck. “You piss me off with that self righteous attitude of
yours. Ah...fuck...I can’t wait to make a fucking mess of you.” He snarled as
he could feel Izuku squirming more.
“Ah! Mnn! Yes harder!” Izuku moaned out to him. “The way...you look down at
everyone...just makes my blood boil! How every little act of kindness is an
insult to you! How the very thought of being nice is like poison to you!
You...ah yes! You’re a….a….”
“Come on….!” Bakugou grunted.
“...a...ahhhh...a JERK! AH!” Izuku’s hips jerked as he climaxed, tightening
around Bakugou who released inside of him moments later.
The two sat there. Panting. Glaring. Bakugou visibly shuddered in the
aftershock of his climax. Izuku took notice. He looked more visibly relaxed.
Not tired. But relaxed. Like a weight had been lifted.
“You’ve got some fucking nerve.” He said after he caught his breath. “Looking
at me like the way you did.” Bakugou scooted against the wall and fixed his
pants. “But I get it. Why All Might chose you.”
“Eh?” Izuku looked at him while he fixed his own pants too.
“This doesn’t change anything between us! Got it?” Bakugou then clarified.
“You’re still a piece of shit. You’re still a fucking loser. You couldn’t even
pin me down without having to use some dirty tricks! Fucking pervert!”
He looked at Bakugou and sighed. “I know.”
Their silence was interrupted by footsteps. “What a mess. Are you serious right
now?”
The pair of boys looked up at Aizawa sensei.
“Jeezus. You two again? Fighting. Out after curfew. Using your quirks.
Destruction of school property. You really want to get expelled don’t you? Come
with me. Both of you.” He instructed.
“Tch! Whatever.” Bakugou got up and Izuku trailed behind him.
 
----------------
The pair were put on suspension for their behavior, after much talk between
Aizawa and All Might. They were put under strict training regimes with Aizawa
for a week. It was merciless but they managed. It was more of a punishment for
Izuku, who was questioned about the marks on his body. As he tried to avoid the
question, Bakugou would smirk in the background. After all, he was in great
form now. He felt a lot less tense.
He wouldn’t mind picking a fight and marking up that nerd again if it ended the
way it did this last time.
