Kirishima liked to train with Bakugou. There was no other student in the hero course that was as tough as an opponent than the angry blond and Kirishima liked his opponents tough. It was manly to fight a guy that gave his 100% in every battle, aiming to be the best of the best. It made Kirishima give his all, too, and that in turn boosted his fighting skills - and made his body swell in muscle.
So, yeah, the redhead liked to train with Bakugou but there was still one downside to that. If Kirishima was the buff meathead type, becoming thick everywhere in his body, Bakugou was the opposite. His muscles were lean, boosting his agility, but there were also some body parts that became thicker. His thighs, for instance, God, those could easily crush his head if the redhead was ever to end up between them. Bakugou’s arms had swelled, too, and his pecs… Well, in the secret of his own bed at 2 am in the morning, when he couldn’t fight his fantasies anymore, Kirishima called them tits. Man, he loved his own human barrel of a body but couldn’t help but fall for the hourglass figure of his best friend. Bakugou was just too hot for the redhead to handle.
It was even worse when they decided to train with their hero costumes on. The red X that marked Bakugou’s top really emphasized his heavy chest and his belt made his chest look even smaller. Sometimes Kirishima wondered that if he tried to grab that waist with his hands would his fingers touch each other. So yeah, Kirishima really liked the blond’s hero costume and he was made painfully aware of that fact as Bakugou pushed him against a wall and blasted him into oblivion. Even though his hardening cracked and the explosions hurt his skin, he couldn’t help but imagine their position in a different kind of situation, where Bakugou would blast his brains out in a good way. Maybe he would even get to see if his big hands really could encircle that tiny, tiny waist as they rubbed against each other, Bakugou’s own hands keeping him trapped against the wall, pulling his red hair and his tongue licking the insides of his mouth, drawing blood when tracing his shark teeth. Kirishima let out a small groan, as his fantasies got a little out of hand.
That groan got Bakugou to notice the bulge in the redhead’s pants. God, he was so hard it was almost painful. Even though Bakugou had won the battle, Kirishima was winning the war by how much he was enjoying the blond’s presence. Bakugou averted this gaze, his cheeks tinted pink. So pretty, Kirishima thought. The blond had stopped his explosions but still loomed in front of the redhead. Then he took a few steps back, letting out a long sigh. Still not looking into Kirishima’s eyes he mumbled something that sounded like “I’m gonna hit the showers” and the redhead was left standing alone on the training grounds.
“Wait a minute, Bakugou!” Kirishima shouted after him. He quickly adjusted himself and ran after the blond.
When he entered the locker room he found Bakugou there still in his hero costume. He was sitting on the bench with his face on his gloved hands. It immediately made Kirishima’s heart ache. Had he messed up their friendship? Maybe Bakugou was so disgusted with him that the blond didn’t want anything to do with him anymore?
“B-bakugou, what’s wrong?” he asked, voice trembling.
The blond slowly lowered his hands, lifting up his head in defiance. As if Kirishima had challenged him in some way. Their eyes locked, red on red, beautiful crimson meeting piercing scarlet. Bakugou’s gaze was so intense Kirishima felt like he was being sucked into a pool of red, framed by the black eyeliner Bakugou was sporting under his hero mask.
“Come and kiss me, Shitty Hair”, the blond told him.
All of Kirishima’s fears deflated and he felt a smile so big creep on his face that his cheeks hurt.
“You sure? You don’t mind- is it really okay for me to- like, you didn’t mind what just happened out there?” Kirishima was stumbling through his words.
“Idiot”, Bakugou told him, sounding clearly pissed off.
“I never mind when it’s you”, he continued, a bit softer.
“Later on, when we’re done kissing, I want you to help get rid of that beast in your pants” he told Kirishima, familiar smugness finding its way to the blond’s voice.
Kirishima turned redder than his hair, but his smile didn’t falter.
“This beast definitely doesn’t mind if it’s with a beauty like you!”
Bakugou snorted. When they kissed, they were both bright red on their faces, embarrassment mixing with the hunger and heat boiling in their guts.
Kirishima really loved training with Bakugou but this training session was definitely the best ever.
