Sparks Fly (Bakugou x Denki)

Part 1

"Kaminari!"
Denki's head jerked up at the shouting. Aizawa was trying to get his attention.
Shit. What were we learning about?
"Uh. Yes?" Denki finally said, trying not to appear too lost. Class 1-A laughed lightly at him, but this wasn't really an unusual occurrence at this point.
"Question #2, Denks!" Kirishima whisper-yelled, trying to be helpful but kind of making it worse.
"Are you ever not spazzing out? Damn," Bakugou sighed, tilting his head back.
"S-sorry! Um. 47?" Denki tried.
Aizawa stared at the wall at the other side of the room. The boy was clearly guessing but at least he came up with something. "No."
Denki laughed out loud, then let his head drop back down to the notebook he pretended to write in. The truth is, his mind was just extremely preoccupied.
He had a one-track mind, and right now it was on the explosive ash blond sitting 2 seats to his left. It had been for awhile. As much as he tried to deny it, he had a crush.
After school, Denki went straight to his dorm. He loved his friends but it was getting difficult to keep acting normal. He was also wildly afraid someone would figure it out somehow, and he could only imagine how pissed Bakugou would be if he knew his friend developed feelings for him.
Denki put some earbuds in and tried to preoccupy himself with homework. Might as well.
Am I so desperate for a distraction that I'm about to do homework?
Yes he was. He stared at the page from today"s algebra class trying to remember literally anything from Aizawa's lecture. He remembered the way Bakugou scolded him, and for some sick reason he kinda liked it. The deep voice, the casual cursing, a pair of crimson eyes narrowing at him. Most people's eyes have flecks of different colors in them, or different hues in the middle. Katsuki"s were wholly red, with a darker ring around the edge of the pupil. Solid, honest, and bold.
Denki dropped his pencil, startling himself.
Dammit! I did it again.
He couldn't stop his mind from wandering. He slammed down his textbook and accidentally shoved it off the desk. It landed with a louder than expected *THUD* on the floor. He buried his face in his hands and groaned in frustration.
*knock* *knock*
"Denks?" Kirishima called from outside.
Of course someone heard that. I'm an idiot.
Denki opened the door to a concerned looking red head... and an explosive blonde.
Fuck.
"Hey guys, what's up.?" Denki started casually, as if he didn't already know. "We heard a crash. Or something. Um.. you good in here?" Kiri asked, not waiting for an answer before peering over the smaller boy to the examine the room.
"I, uh, dropped my book! Dang Mathematics just isn't for me," He put a sheepish smile on his face to appease his friends.
"Well you don't have to beat  yourself up over it, dumbass."  Bakugou said flatly with his arms crossed over his chest.
"I just dropped it, I'm fine," Denki said again, apparently not convincingly enough. Kirishima walked over to pick up the book and set it back on the desk. "If you have questions, you can ask either of us. Or find Aizawa! No shame in getting a little help," Kirishima flashed a toothy grin that made Denki relax just a little. "I know, thanks for the offer," he said, trying to let him down easy. He was still too untrusting of himself and his new feelings to try to deal with social interactions right now. "Don't let it stress you out too much, bro. Hang tough!" Kiri fist-bumped him and started back off toward his own room. Bakugou leaned against the door frame and watched the redhead turn the corner out of sight. "You're even dumber than you look," he grunted and pushed his way into the bedroom. "Uh- w-what?" Denki sputtered. Katsuki picked up a notebook from the desk and opened it to the most recent page. "Yeah, no, we're doing this RIGHT now," he scoffed.
"I've got it under control-" Denki stared to protest again, but a firm hand wrapping around his arm made him stop.
"You're clearly flunking and stressing out of your mind. Kirishima might be fooled, he trusts you too much. But I'm not an idiot and if you're too stubborn to ask for help then you're just gonna have to shut up and take it," Bakugou pulled his friend into the chair and sat him down.
Shit, he really has a way with words. Does he have to talk like that?
Knots formed in Denki's stomach. He tried to get over the sudden touch and aggressive words, forcing thoughts out of his head.
"You really don't have to do this," He forced out and willed his voice not to shake.
"Like hell I don't. We've been friends for how long, Sparky? I'm not letting you fuck up your senior year!" He retorted, his grip tightening around Denki's small arm as if he thought he'd try to run away.
"I'm not trying to!"
"Then what the hell have you been doing all semester?"
Thinking way too FUCKING much about you!!
He hadn't meant to say that out loud. He didn't. It just burst out. Panic spread through his chest and he tried to remember how to breathe. "I mean-  not that- it's not-!" He tried to form another sentence but he couldn't put any thoughts together. He heard a low rumbling which he quickly recognized as a chuckle. Was Bakugou... not furious? He wasn't going to scream at him or say how disgusting it was or stomp away?
"You really thought I didn't know?" Katsuki's lips twitched up slyly.
What. The. Fuck is going on right now?
"You- what- how would-?" Denki tried his best to make the question work, but now he was stunned for a whole other reason.
"I would have to be even denser than you to not have suspicions, at least. Come on, we used to hang with the squad every weekend and now you hardly come out. You stare at me so much in school I might as well be the new chalkboard. You can't form a coherent sentence after I make fun of you but you have a pompous comeback for anyone else. You're stiff as a board as soon as I walk in the room, and I'll bet..." he slowed his rant to a pause. He brought his large calloused hands to Denki's narrow shoulders and trailed his fingertips down the boy's arms. Denki sat frozen still, completely thrown off and unsure of what to do with himself.
"I knew it," Bakugou whispered by his ear. "You've stopped breathing entirely." Denki tried to inhale after he realized what Katsuki said, but the air got stuck in his throat, making an audible sound. He wanted to kick himself.
Another low chuckle rolled from the explosive boy's chest. "Goddamn, Sparky. That flustered already?"
Denki's mind grabbed at words desperately. "What do you mean?" He managed to ask.
"It means that if you're made breathless by a simple touch, then the rest of what I want to do you you would put you in a coma,"  Bakugou said, sending an undeniable shiver up Denki's spine. A violent blush painted his face and he was immensely glad Bakugou was behind him and couldn't see. "Shouldn't you be angry with me?" He was still so confused. And extremely aroused.
"Nah, I've had some pretty incriminating thoughts about you myself. I hadn't planned on doing anything about it, but you're really testing me right now," Bakugou reached down and toyed with the white cotton crop top that Denki had completely forgotten he was wearing when his friends knocked on his door in the first place. Katsuki slipped one of his warm hands in the shirt and felt up the flat, toned stomach underneath.
Is this actually happening right now?

AN: Smut in chapter 2 😅 the intro took way longer than I planned. I haven't written for fun since I was a teenager
