~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

"Next in the ring is Katsuki Bakugou!" The crowd erupts into cheers and clapping. Bakugou returns a sly smirk to the crowd above. "Up against Bakugou is Eijirou Kirishima!" The crowd erupts once more for the other student. Kirishima smiles wide and gives a thumbs up to his opponent. Bakugou scoffs.

"I'm gonna kill you shitty hair," Bakugou says. Kirishima's shoulders drop and he had an annoyed look on his face.

"Come on man! We were a good team in the cavalry battle! And my name is Kirishima." Ms. Midnight clears her throat to get the boys' attention.

"Boys are you ready to start?" Both nod and brace themselves to fight. "On your marks... get set... GO!!!" The boys barrel towards each other at full speed, Kirishima hardens up his upper half while Bakugou comes flying with sparks in his hands.

"DIE!!!" Bakugou screams. Kirishima blocks his fiery punch with his quirk and there's a punch back. Bakugou uses Kirishimas's shoulders to flip onto the back of him, blasting him forward with his own quirk. Kirishima noticeably paused for a second, processing the new feelings that just washed over him.

~~~

"Hey, Bakugou! Congrats on first!" Kirishima said, going to give him a high five. Bakugou just scoffs.

"It wasn't even that hard. Shitty half and half went easy on me."

"Cmon man! His ice walls are nuts! You did awesome!" Kirishima smiles nervously as Bakugou furrowed his brows at him. "Anyway, that's not exactly why I came to talk to you."

"What could you possibly need to bother me for shitty hair?" Bakugou said. Kirishima pouted at the name.

"Stop calling me that, I wanted to confess something." Bakugou tilted his head curiously. "Well, during our one-on-one battle..." Kirishima blushed hard.

"Spit it out already I don't have time for your bull shit," Bakugou said. At this point, everyone left the break room and went to go have dinner in the food court. It was just the two of them.

"Please don't blow me up but I kinda liked the way it felt to get hurt by you!" Silence fell over the room.

"Heh, you dumbass."

"That's better than you killing me," Kirishima said, finally exhaling.

"Come over tonight. My house. I'll text you the address." Bakugou walked out of the room and closed the door, leaving Kirishima in suspense.

~~~

Kirishima stands at the front door of the Bakugou residence, trying to build up the courage to ring the doorbell. He paced back and forth in front of the door, thinking about everything that Bakugou could do to hurt him for what he said. Right as Kirishima lifts his hand to ring the doorbell, Bakugou opens the door.

"How long are you going to stand there?! I was waiting for you to ring the bell but you're being too fucking slow," Bakugou yells, pulling Kirishima into the house by the ear. "Take your shoes off, no one is home, I'll be upstairs," Bakugou said, disappearing up the stairs.

"Okay," Kirishima says to himself. He takes his shoes off and walks into the house, looking around before he goes upstairs. He finds Bakugou's room quickly and slowly walks into the room. "Um, cool room bro," Kirishima said, trying to break the awkwardness. Bakugou grabs Kirishima by the collar, pulling him in close.

"I'll be honest with you shitty hair, I like you," Bakugou smirks and pushes Kirishima onto his bed. "Finally someone who likes how rough I can get." Kirishima looks around nervously. "Come on shitty hair don't you want to have fun with me?"

"Well, yeah!" Kirishima said, sounding a little more excited than he meant to. Bakugou just smiles and gets in Kirishima's lap, gripping the sides of his neck. Kirishima moans without thinking. Bakugou starts grinding on Kirishima's lap, feeling him get hard.

"So pathetic, I just sat on your lap and that's all it takes?" Kirishima covers his face and peeks through his fingers. Bakugou scoffed, pushing Kirishima so he fell back onto the bed. "You said you wanna feel pain right?" Kirishima nodded profusely. Bakugou took initiative, pulling Kirishima over his lap.

"O-Okay, I know I said I liked the pain but could you be a little nicer to me?! Verbally?!" Kirishima said, a little bit of terror in his voice. Bakugou relaxed his tense muscles, looking at his friend over his lap. 

"I guess I could, but don't expect me to be nice to you all the time got that?" He pulled Kirishima's pants down just enough to expose his ass. He gently rubs Kiri's ass, gently smacking it a few times. "Ready?"

"R-Ready for what?"

"This," Bakugou winded up and spanked Kiri hard. Kiri yelped at the stinging left behind from the spank.

"D-Did you use your quirk?!" Kiri asked frantically.

"No, but that's a hell of a good idea!" Bakugou smirked at Kiri as tears welled up in the bottom's eyes. Bakugou wound up for another spank, releasing a few sparks from his palm. "This one is definitely gonna sting Kirishima," he said, landing another hit on Kiri's other asscheek. 

"Fuck!~" Kiri moaned. "Damn that fucking hurt Kats!~" Bakugou smiled devilishly at Kiri before his expression quickly changed to one of shock.

"Did you seriously just cum from that?!" Kiri's face also turned to one of shock as he noticed the sticky feeling in his boxers.

"Uh, yea- guess I did," Kiri laughed nervously. 

"Damnit shitty hair."
