Kaminari has been harboring some feelings for his best bro, Kirishima. When he accidentally blurts out his very feelings for the redhead, how would things turn out?

- Contains Smut.


The summer heat bombarded every single place on Earth, making most, if not all places on the planet so hot you could cook on the pavement, and Yuuei happened to be one of those places. Thankfully for the students, it happened to be the weekend, so they didn't have to battle both schoolwork and the heat. The airconditioning in the dorms greatly helped them battle off the notorious summer heat; it's still hot in some places, but at least most of it is cold, notably Todoroki's room.

Kaminari has burned through all the things he could do alone; video games, magazines, and even homework! So he was just there, in his room, sitting on his bed and staring into the ceiling. He has reached a point to where he wanted to have the company of a person.

The company of a specific person, however.

Kirishima invaded his thoughts every second of everything that he does. Red-haired character? Kirishima. Red car? Kirishima. Red laser beams? You guessed it! Kirishima! Even things that are supposedly happy and full of life remind the blonde of Kirishima, such as the bastard sun outside!

"YELLOW CAR!"

Kaminari immediately redirected his attention to the video game he is playing, his character shouting the aforementioned words, but alas, his character immediately got "Wasted", being run over by a yellow car. Kaminari started fuming.

"God-fucking-damn it!" Kaminari cursed as he threw his controller to his bed, the device bouncing around the mattress before settling. Kaminari sighed afterwards, plopping himself face-down on the bed.

"Kiri.. why do you do this to me..?" he mumbled on the mattress as his face flushed red.

Kaminari knew that he felt something for the redhead, but brushed it off as nothing more than platonic appreciation; Kirishima's drive to being a hero, his optimism, his caring behaviour, it just drove the blonde closer to him, and they eventually became best bros. As time went by, however, Kaminari's thoughts escalated, adding how good-looking Kirishima happened to be, admiring his nice, chiseled face, his bright smile, and all those muscles he has on display. Those are a nice set of biceps, pecs, and abs that Kirishima has..

I wonder.. how hard they are? It wouldn't hurt to just feel them, right?

Kaminari's thoughts quickly went to the gutter from there on in. Must be the sun frying his brain, or perhaps his quirk is slowly short-circuiting his brain thanks to the heat. It's always the heat. Kaminari doesn't deny though, on how sexy Kirishima is. But he felt kind of inadequate when he compared himself to the redhead, having a lean figure with not so much muscle.

But even with those thoughts, Kaminari and Kirishima are still best bros, and the blonde is really trying his best to hide all of that information from Kirishima, fearing he'll distance himself from the blonde as a result. But being bros, they both know that they can confide in each other; Kaminari is just too unwilling to take that risk.

And that's how Kaminari found himself knocking on Kirishima's door, needing the redhead's company. Good thing Bakugou is away too, otherwise they wouldn't be as alone as they should be. It's not fun when someone's telling you to shut up and being threatened with explodo-death.

"Coming!" Kirishima said from behind the door, followed by the sounds of footsteps approaching, then the creak of the door being opened.

Kaminari wasn't prepared for the sight about to present to him.

Kirishima opened the door, and on noticing Kaminari, flashed a bright smile that could rival the sun, but that was only a small portion of why Kaminari's face turned bright red; Kirishima just stood there with nothing but his boxer briefs on, shamelessly displaying his muscular assets to Kaminari. He could see redhead's muscles twitch as he moved.

Don't head to the gutter, Denki! Don't head to the gutter!

"Kamibro! What brings you here?" Kirishima asked, his bright smile unwavering.

"U-uumm.." Kaminari was rendered speechless by the sight before him. "W-well, I uhh.. why are you half naked, for starters? Hehe.." Kaminari blurted out nervously as he looked to the side and played around with his fingers.

"Oh uh, it's just so hot, ya know? I just wanna be as cool as I can be, even with the aircon on. Soo.. yeah!" Kirishima replied energetically, but on noticing Kaminari's flustered and nervous demeanor, he changed his tune a bit. "Something wrong, Kami?"

Kaminari couldn't meet Kirishima's gaze, still flustered and too embarrassed to see Kirishima's body. "I'm just not used to.. that, hehe." the blonde quickly pointed at Kirishima's body, and the redhead got the message. "Ohh, alright. I'll put some clothes on, just a sec." Kirishima closed the door and dressed quickly. A few seconds later, he opened the door for Kaminari, and he was now dressed with a red tank top and black shorts.

"Do you wanna come in?" Kirishima asked the flustered blonde; Kaminari nodded, and Kirishima moved out of the way to let the blonde through. Shutting the door behind him, Kirishima went to Kaminari, who was sitting on his bed. Kirishima sat down beside him.

"So uhh.. what's up? Are you alright?" Kirishima asked Kaminari as he patted his back. The blush mostly faded from Kaminari's face, and he was able to regain most of his composure. "Oh uh, I just needed some company, that's all. It gets boring when I'm alone in my room." the blonde said.

"Hehe, alright." Kirishima patted Kaminari's back two more times, then standing up to look for some things in his drawer. "But I just can't shake the feeling that something's bugging you.." Kirishima asked, bringing out some notebooks from his drawer.

"Why do you think so? Am fine." Kaminari spoke too softly, and he found himself staring too long at Kirishima; he looked away immediately on realizing that. Kirishima figured there was something bothering the blonde. The redhead placed his notebooks aside and went back to Kaminari, sitting beside him again.

"Kami, you can tell me. I can tell that something's eating you up from the inside." Kirishima placed an arm over Kaminari's shoulders in an attempt to reassure the blonde. Kaminari flinched at the sudden contact. "I'm not that dense, Kami." Kirishima added. "Am fine! Really!" the blonde shouted angrily, and he moved away from the arm, being uncomfortable with the contact. Kirishima retracted his hand and looked hurt, and stood up to fetch his gaming controller, which he tossed at to Kaminari.

"Well, I have some games you might like there. Have fun." Kirishima said dejectedly as he grabbed his notebooks and started reading through them. Kaminari looked at the controller, then to Kirishima, visibly saddened by the redhead's sudden change of behavior.

Come on! He's your bro! Besides, seeing Kirishima sad would make anyone sad; even Bakugou..

It won't hurt to tell a bit, I guess.

JUST a bit, Denki!

The blonde tossed the controller aside, and went to the redhead. "Okay.. I'll tell you.. some." Kaminari said to Kirishima as he placed a hand on the redhead's shoulder. Kirishima perked up a bit on hearing that, but still looked a little upset.

"Look, man. I just feel.. sad.. when I can't help someone, and even worse when they don't want me to help them. I just feel so useless.. I hate feeling like that." Kirishima said to the blonde, going to him for a tight bro hug. Kaminari reciprocated.

"You're not useless, Kiri. Trust me on that. You've helped a lot of people, me included." Kaminari smiled into the hug, and latched tighter onto Kirishima. On seperating, the redhead turned back into the ball of sunshine he usually is.

"Thanks for that, Kami. But now, this is about you, so.. tell your bro! I'll help you with it as much as I can!" Kirishima fist pumped into the air and grinned widely as if he won the lottery. Kaminari smiled, but is still nervous on telling him even a little bit. He cleared his throat before beginning.

"Alright uhh, soo.. umm.." Kaminari started shakily. Kirishima kept silent and listened.

"There's.. someone.. that I like.." Kaminari paused. Kirishima's eyes went wide, and he smiled too. "Ohhh, it's a love thing." Kirishima's smile turned bigger, which slightly distracted Kaminari. "Yeah.." the blonde added, a bit of fear in his voice.

"I'm just.. scared. I don't know if the person would like me back, and if I tell... him.. and the fact that he's in our class.." Kaminari turned bright red and looked away from Kirishima out of embarassment.. and with a bit of fear.

I think I told him too much already..

"Him?" Kaminari peeked, and Kirishima's eyes bore a look of curiousity instead of the feared disgusted look that Kaminari was anticipating. The blonde deemed it kinda safe to indulge the redhead with just a little bit more. "Y-yeah.. him.." Kaminari went even redder than Kirishima's hair. The redhead smiled and hugged him tightly, happy that his best bro confided in him about his situation; it made him feel special.

"Kami.. you don't have to be scared. You're still my bro! My gay bro!" Kirishima could hear Kaminari's light sniffles as they hugged, the blonde's emotions overflowing. Kirishima patted his back. "Y-you're not disgusted? At me?" Kaminari retracted from the hug to get a look at Kirishima's face, which had a small smile on it. "That's not a reason to get disgusted at someone, Kami."

"People that think like that are the ones that're disgusting to me." Kirishima adds, making a small smile tug appear at Kaminari's lips. "You really know how to cheer someone up.." the blonde goes back to hugging Kirishima, wanting the warmth and security the redhead offered.

I could get used to this..

After a few minutes of reassuring hugs, the two seperated and Kirishima asked Kaminari about some details of his love problem. Kaminari answered his questions without giving out a specific person in mind, being as vague as possible about it.

Then a killer suggestion came.

"Kami, why don't you try telling the guy you like him?" Kaminari froze and just stared at Kirishima, petrified. Kirishima went from casual to concerned immediately. "Look, Kiri I.. I'm scared." Kaminari muttered with a quiet voice, but looking at Kirishima. "Of what? Their reaction, or the guy in general?" Kaminari nodded. "More of their reaction. I'm just not so sure.. and I don't know what to say either.." the blonde wore a sad look.

"You don't know what to say to him?" Kirishima asks, a bit perplexed. Kaminari shook his head. "That's new, coming from you."

"Well, I guess you could practice on me, for starters." Kirishima stated, smiling brightly again. Kaminari went eyes-wide at the offer.

Then technically, I'm already doing it..

"W-what?!" he sputtered out. "Just imagine I'm that guy you like, and that you're telling him that you like him. I'm just a placeholder. You don't have to be scared of me." Kirishima rubbed and patted at one of Kaminari's shoulders. Kaminari didn't look very happy with the offer, shocked was more like it.

"I-I'm not so sure about that, hehe-" Kaminari looked left and right, avoiding Kirishima's gaze as he repeatedly tapped his fingers together. Kirishima took hold of Kaminari's shoulders and stared at his very soul, making the blonde feel a bit uneasy. "Hey, I bet that if you don't tell him, you won't be able to move on about it and it'll eat you up forever." Kaminari stayed silent. Kirishima shook him gently, playing around. "C'mon, it's better to just get it over with. Besides, if he tries anything on you, I got ya covered, alright?" Kirishima did a mock uppercut. Kaminari laughed a little. The blonde sighed afterwards, and eased up.

"C'mon, Kami! You can do this!" Kirishima attempted to boost Kaminari's confidence with a

determined smile. "I-I.." Kaminari turned red and started hyperventilating. Kirishima rubbed comforting circles on the blonde's back. "Calm down bro. Just relax, I'm here."

I'd like to see you calm down when you're being told to confess to your crush.. even if you didn't know you're mine...

"Let's try that again." Kirishima said, and waited. Kaminari inhaled, and exhaled before trying again, then locking gazes with the redhead.

"I.. like you."

..Eijirou.

Kirishima cheered at Kaminari's success, patting his shoulders and ruffling his hair. "Great! That's a start. Now add his name at the start of the confession."Kaminari had a pensive look on his face, and stayed silent. "I'm giving love advice, isn't this something new? Haha."

Kaminari got too comfortable, and his mouth moved on its own, speaking the very words he was trying to withhold.

"E-Eijirou.."

"..I like you."

The statement just hung there, like dead air. They stared at each other, Kirishima in surprise, Kaminari in shock. Kirishima couldn't believe what Kaminari has just said, the blonde himself more so by allowing those words to leave his mouth.

There goes everything.. I've fucked everything up. Bye bye, Kiribro..

"Kami?" Kirishima broke the silence, sending Kaminari in a panicky state, arms flailing in front of him defensively. "A-aaah! I-it's another Eijirou! H-he's uh, our neighbor back home! Y-yeah!" Kaminari panicked, covering his face with his arms. Kirishima didn't look displeased one bit, but he looked rather amused.

"Kami, you've just said that he's in our class.." Kirishima took hold of Kaminari's shoulders and kept a firm grip on them. Kaminari stopped flailing about, but his face wore pure fear and panic. "..and I'm the only Eijirou in Class 1-A.."

I should just overload and stupefy myself, but I don't want to hurt Kiri..

Kaminari failed to notice the sudden close proximity of Kirishima's face to his, their noses barely touching. "O-oh uh, I did? Must've been a s-slip up! Yeah!"

"Kami. Were you.. referring to me?"

On hearing that, Kaminari knew that the jig was up. He sighed in defeat, his hands flopping on his sides.

"Yeah.." The panic vanished from Kaminari, and was immediately replaced with sorrow. "I-I'm sor-" Kirishima brought him in for another hug, but this one felt more.. intimate. Kirishima nuzzled on Kaminari's neck, flustering the blonde.

"Kami, don't apologize.." Kaminari couldn't bear it, and released himself from the hug, and he tried to stand up and walk away. "I'll just go-" Before he could stand up, Kirishima's hands found themselves on Kaminari's cheeks, and the redhead pulled him in close enough for their noses to touch.

"Kiri what're you-?" Kirishima lovingly caressed Kaminari's cheeks with his hands.

"What does it look like, dummy?" Kirishima laughed a little, then started to inch towards Kaminari's mouth, stopping just enough for their lips to slightly graze each other. "Is it okay if I..?" Kirishima asked for permission, but the knowing look that Kaminari gave him told him just enough.

They locked lips, Kirishima diving headfirst. Kirishima's lips were slightly chapped, but Kaminari's was soft, and the blonde couldn't believe that he was actually making out with his crush, though they only sucked at each other's lips, not delving into tongue just yet. Even with the lack of tongue, it was still a hot and passionate kiss.

They seperated eventually, and Kirishima rubbed their noses together in an Eskimo kiss, then he made their foreheads touch as they looked at each other's eyes. Kirishima smiled, and so did Kaminari.

"I've.. liked you for some time now. I just didn't feel like acting on my 'manly' instincts to confess to you since I always saw you with the girls, and that was like, my answer." Kirishima said rather shyly to Kaminari, who raised an eyebrow at that. "Huh?" Kirishima laughed. "I just thought that you were one-hundred percent straight, dummy." Kaminari looked like as if he was going to say "oh", but dropped it and just grinned.

Kaminari opened his mouth to ask something, but Kirishima already caught wind of it. "You're gonna ask what made me like you?" Kaminari shut his mouth and just nodded. "Hmm.. At first, it was your cute looks." That turned Kaminari into a blushing mess. "But I've learned a lot of new things about you along the way, and I really admire them, especially your drive to protect your companions.." Kirishima gently caressed Kaminari's hair, tracing the black lightning bolt.

This is all just dream, Denki.. it's too good to be true..

Kaminari's suddenly scrunched-up face sent alarms to Kirishima. "W-wait! T-this can't be real! I must be dreaming!" the blonde tugged at his hair. "Why is my brain so cruel?!"

The signs triggered Kirishima to secure Kaminari in a tight hug, holding him in place with his strong arms, and pressed against him.

Kiri really likes hugs. Like, a lot.

"Denki, this is real. You're not dreaming." Kirishima assured his soon-to-be-boyfriend, who was taken off-guard by the use of his given name. "D-Denki?" Kirishima smiled back. "Yeah, Denki." Kaminari pouted.

Kirishima went to lay down on his bed with Kaminari in front of him to spoon. "When you wake up later, you're gonna be here, in my arms. And that'll prove you're not dreaming." Kaminari let out a playful huff. "I'm not letting you go until you accept that it's not a dream." Kirishima pulled the blonde closer to him, their bodies touching. Kirishima then nuzzled at Kaminari's neck. Unable to be free of Kirishima's clutches, the blonde groaned in defeat. "Fine. A nap would be nice, I guess.."

Kirishima chuckled and placed a kiss on Kaminari's cheek as he shut his eyes. "Have a nice nap, Denki."

Kaminari smiled before closing his eyes. "You too.. Eijirou."


SMUT STARTS HERE.

Of all the hot, summer days of the year Kaminari chose to just barge in on his boyfriend's room, it had to be this day, and boy, was he glad he chose today. They had already been together for a month so they're more or less fine with intimate contact. What Kamimari was about to see, however, was on a whole new level.

Kirishima was sprawled on his bed, stark naked. His ripped, hard muscles on full display for all of Kaminari to ogle. What's more titillating, however, is Kirishima's powerful arm moving back and forth as he jerked himself off, his other hand feeling himself up and tweaking his nipples. He was sweaty, and panting Kaminari's name.

"Denki.. nghh.. Denki.."

An idea formed in Kaminari's head, a devilish smirk following suit.

"Heey." he said with a sultry tone, earning wide eyes from Kirishima, who jumped at his sudden presence.

Kirishima went redder as he noticed Kaminari's presence, and even a darker shade of red when he noticed his smirk, and where his eyes were looking at; his hard cock, crowned with a nice tuft of red pubic hair.

"Mmm.. maybe you want.. help with that?" Kaminari approached the redhead and sat down on the same bed Kirishima was sprawled over. The blonde's eyes flickered from Kirishima's red and embarrased ones to his rock hard cock. "Oh uh.. mmm.. if you want." Kirishima spoke huskily with a hint of nervousness.

"Hmm.. then here, Eiji. Let me." Kaminari slowly took hold of Kirishima's cock. The redhead gasped and arched his back at the foreign, yet stimulating contact. Kaminari started jerking it slowly, getting a feel of it.

"That feels so ghhh.. good.." Kirishima groaned. Kaminari felt like upping the game, so using his free hand, he started caressing and worshipping the hard muscle on Kirishima's biceps, then slowly going to his pecs.

They're so hard, rock hard. I like them.

Kaminari slowly lied down on his side beside Kirishima. Using his mouth, Kaminari attacked one of Kirishima's nipples by licking, biting, and sucking at the pink bud, sending waves of arousal to the redhead.

"A-aah!"

Kaminari continued his attacks on Kirishima; he licked the redhead's muscular body all over, attacked both of his nipples, then his lips, their tongues being entertwined in a hot, lewd, sensual dance. Kirishima's breathing became ragged, and he was much sweatier now as he received stimulation overloads.

Kaminari's pacing on Kirishima's cock also intensified, his hand moving faster by the second to the point that the redhead's cock started leaking precum.

"I-I'm close!" Kirishima said in-between ragged breaths before quickly bringing Kaminari's lips to his, engaging in another hot dance of tongues as the tell-tale signs of small amounts of cum starting to spurt from Kirishima's cock signaled that he was close.

"Going to-!"

With a gasp of air, Kirishima came, the string of white liquid making it's way to his body.

"-cum!"

And it soon made contact with his cheek, then his pecs, coating both surfaces with the hot and shiny white liquid. The fluid dripped along Kirishima's cheek and the median of his pectorals, but Kaminari went in to lick it off him, starting with his pecs. Kaminari's hot tongue brushed against Kirishima's hard muscle to scoop up the redhead's cum, making swirling motions around his chest and the small pool at the median then going for his nipples, licking at them again.

Done with his pecs, Kaminari went to Kirishima's cheek, cleaning up the stray cum with two licks. After that, Kaminari sat up and eyed Kirishima just as he swallowed his cum. A small bead of the white fluid found its way sliding down the side of Kaminari's mouth.

By this time, Kirishima's breathing has evened out, and has just recovered from his climax. He's tired and sweaty, but he didn't fail to notice the tent with a wet tip on Kaminari's pants. The couple stared at each other with lust filled gazes.

"You're so hot, Eiji. I-I'm just.. at a loss for words." Kaminari smirked at his boyfriend, who smirked back. "How about you, Denki? You look like you need help." Kirishima pointed to the tent in Kaminari's pants and winked. The blonde looked down on his problem and smiled deviously.

"Mmm.. help me out, Eiji." Kaminari's devious smile grew. Kirishima knew what that meant, and so he sat himself up and palmed the hard cock underneath Kaminari's pants.

"Ahh!"

Kirishima grinned, and undid the button and zipper on Kaminari's pants, opening it up to see the bulge covered by the blonde's black and yellow underwear, which had a wet tip on it. Kirishima caressed the bulge, earning soft moans from Kaminari.

"E-Eijirou! A-ah!"

Kaminari covered his mouth to prevent any more moans from escaping. Kirishima grinned at the lewd noises that his boyfriend made, and continued to feel up the bulge on the underwear.

Kirishima lightly shoved Kaminari against the wall, then he pulled down the blonde's underwear, letting his length spring out. It was already leaking a rather copious amount of precum, and twitched from time to time.

Kirishima licked his lips, and brought his mouth to Kaminari's hard cock. He started licking the length from base to top, turning Kaminari into a whimpering mess. Kirishima repeated the action a number of times, then he went for the head, kissing it and bringing it into his mouth as he sucked on it.

"J-just.. watch the teeth-ah!" Kaminari exclaimed from the pleasure, yet worried about his dick getting shredded to pieces by his boyfriend's shark teeth. The redhead paused for a bit, and winked at the blonde, getting his message.

After sucking on the head, he slowly brought Kaminari's cock inside of his mouth, his tongue caressing it all over as it went in. Kirishima then started sucking on the length as he slowly bobbed his head back and forth. Kaminari was loving it, getting lost in a flood of lust as he felt Kirishima's hot mouth and tongue all over his dick.

Small sparks started to emanate from the blonde, the huge amount of pleasure overflowing within him. Kaminari was trying his best to not overload from all of what he's feeling, since he might hurt his boyfriend, especially while his dick is in the redhead's mouth. Then he felt a surge inside of him, and wasn't sure if he was going to cum or overload himself.

One of Kaminari's hands grabbed Kirishima's cock, which was hard again. He started to rapidly stroke it, wanting to see his boyfriend cum again. His other hand went to Kirishima's head, grabbing his hair to make him bob faster, intensifying the experience.

Then he felt a surge inside of him. He wasn't sure if he was going to cum, or overload; or both.

"E-Eijirou!"

With a shout of his boyfriend's name, he came in Kirishima's mouth, the white fluid filling up the redhead; Kirishima came again with him, his own fluids coating himself again. What the blonde wasn't aware of was that he also overloaded himself, sending a huge electrical charge all over the room; it destroyed the lights, Kirishima's electronics, and unfortunately, the airconditioner.

Thankfully, Kirishima's hardened state wasn't a good conductor, so he was more or less unaffected by the electrical surge his boyfriend unwillingly released along with his willingly released fluids.

Kaminari suddenly flops down on the bed sideways; he passed out from both short-circuiting himself and the tiring activities with his boyfriend. As Kirishima released the semi-hard and dripping dick from his mouth, swallowing the cum in the process, he looked to see his boyfriend unconscious. He pouted and huffed, thinking that he'll be left to clean this whole mess by himself.

And so he went to the bathroom, carrying an unconscious Kaminari on his back. Once there, he stripped him of his clothing, and began washing him along with himself. Once Kirishima was done bathing him and Kaminari, he glared at the broken airconditioner, and took his blanket to wrap around Kaminari.

With his room starting to heat up, he went to the blonde's room downstairs, thankful that no one was around to see them in their current predicament; Kirishima in nothing but shorts and Kaminari wrapped with his blanket, riding piggy-back on the redhead. Once Kirishima is at Kaminari's door, he lightly shoved it and the door opened. Once inside and after locking the door, he gently set the blonde down on his bed, and followed in afterwards, spooning the blonde and falling asleep rather fast.

Hours later, Kaminari woke up past midnight, and he was confused on finding himself naked and wrapped up in Kirishima's blanket, and even more so on finding that he's in his room. He tried to get up, but found himself unable to due to a pair of strong arms wrapped around his torso.

What hap-?!... oh right, we did.. stuff. But we did it in his room. How did we get here?

"Oh, he must've carried me here, but why? We could've just slept on his bed.." he said to himself as he smiled and rolled his eyes at the thought, but on finding himself drained of any electric energy, he could deduce that he overloaded himself, which meant..

Kirishima's aircon..

He frowned and face-palmed at himself for overloading. "Must be like a fricking oven in there already.." he sighed and shook his head. He turned to look at his peacefully sleeping boyfriend, who was sleeping, smiling, and drooling on his pillow; he chuckled at the sight, but was a bit squicked by the drool coating Kirishima's part of his pillow. Kaminari rested his head on his pillow, looking at the redhead's sleeping face and cupping a cheek.

"I know that you'll forgive me, that I didn't mean it, blah blah blah. But I'll still make it up to you somehow." then he pressed his forehead against Kirishima's, and closed his eyes, falling to sleep once again.

G'night, Eijirou.
