Kirishima and Bakugo have been dating for almost a year now in secret.

Kirishima wanted to have their relationship be public but Bakugo didn't because he was (even if he didn't want to admit it) scared of how everyone would react.

Currently, both boys are in Kirishima's dorm room. It was getting late so Bakugo had told everyone that he was going to sleep.

Kirishima being Kirishima told everyone that he was going to head to bed as well after a few minutes leaving them all kind of suspicious but not too suspicious.

"Baby I'm bored~" Kirishima whined as he looked down at Bakugo.

The blond boy was lying on top of him scrolling through Tumbler on his phone, cuddling his needy boyfriend.

"What do you want to do?" Bakugo asked with a sigh as he turned his phone off.

"Kiss!" Kirishima answered with a large sharp-toothed grin.

Bakugo smiled at the redhead's adorableness and complied, leaning up and kissing him.

The kiss started out innocent and pure.

Well, that was until Kirishima sat up, Bakugo now straddling him. He moved his hands down to the blond's waist and turned his head, deepening the kiss.

Bakugo moved his hands up to Kirishima's hair and tugged at it accidentally.

Kirishima let out a moan into their kiss, blushing brightly afterward.

The two had given each other handjobs and blowjobs before so they each knew what the other sounded like when they moaned and also knew what each other looked like. Even still Kirishima was always flustered whenever he moaned or let out any noise similar to one.

Bakugo on the other hand loved hearing Kirishima's noises, they were music to his ears.

"Sorry," Kirishima mumbled against Bakugo's lips, his blush from embarrassment and being flustered.

"Don't apologize, dumbass, I like it when you're vocal," Bakugo mumbled back instantly making Kirishima's blush darkened.

Instead of replying again Kirishima just kissed Bakugo.

The kiss was slow but soon became heated and full of passion.

Kirishima slipped his hands under Bakugo's shirt and took it off, breaking the kiss long enough to get it over Bakugo's head before connecting their lips again.

"Someone's eager." Bakugo laughed as Kirishima took his own shirt off.

"Yeah well, it's your fault for making me horny." Kirishima countered before pushing Bakugo so he was lying against the bed, Kirishima's arms pinned on either side of his head.

"Well, I guess if it's my fault then I should help you out then shouldn't I?" Bakugo asked as he wrapped his arms around Kirishima's waist, pulling him down before grinding up.

The sudden friction made them both let out breathy moans.

"How do you plan on helping?" Kirishima asked before he began to kiss down Bakugo's jaw and neck, slowly moving down to his chest, sucking on his nipples making the blond let out a mewled sound.

"Fuck me that's how," Bakugo said shocking his lover so much that he froze before pulling his head back away from his body.

"Are you sure about that? Are you ready for that?" Kirishima asked knowing that penitentiary sex always hurt when you did it for the first time for the bottom.

"Yes I'm sure dumbass... just don't be too aggressive..." Bakugo trailed off as he looked over to the side.

"Ok, I'll be super gentle. Promise. Still, tell me if it hurts though." Kirishima agreed as he reached over to his drawer and grabbed some lube as well as a condom.

"Why do you have a condom? We are both dudes." Bakugo asked, stopping Kirishima from opening the condom.

"Because it will be easier to clean up after." Kirishima paused before ducking down so his mouth was right against Bakugou's ear.

"Unless you want me to fill you up with my cum. Filly you up until you're so full that you burst. I could take care of you after or I could eat you out~ the option is yours, love." He whispered seductively, his lips brushing against the shell of Bakugo's ear every now and again.

Bakugo blushed darkly at the thought before taking the condom out of Kirishima's hand and throwing it across the room.

Kirishima smirked at the blond as he looked down at him.

"Good choice, I won't make you regret it." He hummed as he began to take Bakugo's pants and boxers off, quickly taking his own off as well.

Kiri then applied some lube to his fingers before putting one inside Bakugo's twitching hole.

Bakugo made a face but didn't do much more.

"Are you okay?" Kirishima asked as he got to the bottom knuckle.

"Yeah, I just feels a little weird," Bakugo answered as Kirishima peppered kisses along his chest.

"Can I add a second one?" Kiri asked, receiving a nod after a minute.

So Kirishima added the second finger getting a whine of pain from the blond.

"Are you alright? We can stop, we don't have to keep going if y-" Kirishima was cut off by Bakugo pulling him down for a kiss to shut him up.

"I'm fine, I want this. It just stings a little, my pain tolerance is high so stop worrying about me." Bakugo said once they pulled apart.

"I know but I don't wanna hurt you on accident," Kirishima said as he began to scissor his fingers.

Bakugo shuttered and let out a quiet moan when he brushed against his prostate.

"Y-you won't hurt me. Now go back to where you just we-" Bakugo cut himself off with a louder moan when Kirishima found his prostate again, this time his fingers moving on it. Purposefully pleasing the blond so his legs began to shake.

Kirishima stopped when he realized Bakugo was close and pulled his fingers out.

Bakugo instantly let out a whine of protest but only got a kiss on the nose in response.

Then without warning three fingers were inside of his ass. His body jolted at the sudden feeling as tears pricked his eyes.

"We can still stop if you want to Love," Kirishima reassured as he used his other hand to wipe the fallen tears from his lover's eyes.

"N-no, keep going. I'll get used to it soon." Bakugo insisted as he shut his eyes, taking deep constant breaths to try and calm himself down some and relax.

Kirishima nodded before going back to leaving small kisses along his body.

After another minute Kirishima began to move his fingers, spreading them so he could stretch out Bakugo's tight walls.

After a few more minutes of this, Bakugo began to move his hips down onto Kirishima's fingers, moaning as he did so.

"Do you think you're stretched out enough for me?" Kirishima asked his hard dick now painful from no relief or friction.

"Yeah, I think." Bakugo nodded having Kirishina take his fingers out of him.
He had to restrain himself from letting out another whine.

"Tell me if you want to stop," Kiri said as he lubed his rock-hard dick up, moaning at the feeling of something touching him even if that something was just his hand.

"I know." Bakugo as he watched Kiri line up with his entrance.

Kirishima began to push the tip of his eight-inch dick inside of Bakugo.

He had to restrain himself greatly from just fucking Bakugo like there was no tomorrow. He did restrain himself however because he knows this is Bakugo's first time having sex ever and didn't want to hurt him or lose his trust.

"You're doing so well Katsuki~ just a little more left to go." Kirishima let out soft praises to the slightly older boy when he got halfway in.

"You're doing great baby, I swear the pain will go away soon and I'll make you feel amazing," Kirishima whispered into his ear as he pushed the rest of the way in.

Bakugo was trying his hardest to focus on Kirishima's praise instead of the pain in his ass.

A few tears fell from his eyes but nothing too terrible.

"I'm all the way in, tell me when I can move but take your time to adjust," Kirishima mumbled against Bakugo's neck before continuing his kisses.

Bakugo's tight, warm walls felt amazing around his cock but he didn't want to say anything at the moment about that because he knew Bakugo was in pain right now.

After about five minutes Bakugo took a shakey breath in. "You can move now." He said as Kirishima picked his head up.

"Okay, I'll be gentle. Tell me if I'm too aggressive though." Kirishima said before he pulled out an inch and put it back in.

They continued this for a while, Kirishima taking more out every other time before putting it back in.

He kept to his word and was slow and calm, making Bakugo feel every bit of him move in and out.

"Aah~ fuck! Right there Eijiro!" Bakugo said as Kirishima hit his prostate.

"Faster~ harder~ please~!" Bakugo almost begged as he moved his hips to meet with all of Kirishima's thrusts.

So Kirishima complied and went slightly faster and harder than before, hitting the boy's prostate head-on over and over again.

Bakugo was a moaning mess under him now and fuck was it hot.

"Shit! Eijiro~ I'm close!" Bakugo moaned aloud only having Kirishima go faster than before as a response.

"Me too Katsuki~ cum with me baby," Kirishima whispered huskly into Bakugo's ear making the blond shiver and nod.

A minute later Bakugo came with a loud moan of Kirishima's name, swiftly sending Kirishima into his own orgasm.

Bakugo shuttered in pleasure at the feeling of Kirishima's warm seed filling him up.

"Fuck Eij." Bakugo panted as he and Kirishima caught their breath before Kirishima pulled out.

He sat back and watched his cum drip from Bakugo's pink and stretched asshole.

"Do you want me to eat you out or get you clean with a towel and bath?" Kirishima asked sweetly as he kissed Bakugo's forehead.

"Bath," Bakugo answered, struggling to keep his eyes open.

Normally he would have picked being eaten out but holy shit he was tired.

"Okay baby, let's go get you into the bath." Kirishima agreed as he picked Bakugo up and carried him into the bathroom.

He then helped bathe Bakugo and himself before getting them both dressed and carrying the mostly asleep Bakugo back to his bed.

"So how was it?" Kirishima asked wanting to know if he was bad or too aggressive or something so he could do better next time.

"Amazing. Now let's sleep, I'm tired as fuck." Bakugo said as he cuddled up to Kirishima's chest.

It was already ten-thirty and he was used to going to sleep two hours ago so he was even more tired.

"Okay, I'll still try to do better next time if you want to have a next time. Love you, goodnight." Kirishima said as he ran his hands through Bakugo's hair.

"It was good this time, don't worry about it, baby. Also, there will definitely be a next time. Love you too, night." Bakugo said before falling asleep leaving a very satisfied and happy Kirishima awake.

Eventually, though, Krishima fell asleep too, a peaceful smile resting on his lips as his grip on Bakugo relaxed.

***Bonus!***

"Kirishima, Bakugo, you never told us that you were together! I really wish you had so we didn't have to find out like we did last night." Denki said shuttering when he saw the couple walk into the lounge room.

"What do you mean Dunce face?" Bakugo asked with a harsh glare.

"He means you two were very loud in the dorm room last night while you fucked." Todoroki deadpaned instantly having both Kirishima and Bakugo blush darkly.

"Lucky me, I had headphones." Jiro laughed, tapping the dark purple headphones around her neck.

"Same." Everyone but Denki said.

"Really? I was the only one that had to suffer and hear them? Wow, guys. That's cold." Denki said as he crossed his arms.

Everyone laughed and with time dropped the topic.

And that's how Kiribaku accidentally came out to all of class A.
