Kirishima was worried and missed his boyfriend. He hadn't seen him since last Friday. They had spent all of winter break together. And Katsuki had said that they would meet up again before school starts up but Kirishima hasn't heard from him.
Eijirou had only heard from Katsuki's mom that he had gone to the doctors and hasn't heard anything since. Kirishima was worried, he hadn't seen or heard anything for a week and a half. Then school started up again.
So here he is. Sitting in 3rd period panicking since:
1- Katsuki is never late to school.
2- He hasn't seen him in over a week
3- His last known location was a doctors office.
Kirishima was whole heartedly panicking. What if something happened? What if he was super sick and Misturi just hadn't found a way to tell Kirishima? What if a villan got him-
Suddenly the door to the classroom slammed open. Kirishima's head whipped up. As did everyone else's in class. There stood Bakugo a tight lipped grimace on his face. Mic didn't miss a beat.
"Katsuki. Please refrain from slamming my door. Please take a seat." Mic moved back to the board paying no mind to the firey blonde now stomping to his seat. Everyone moved to follow Mic's lesson again. Except Kirishima was busy trying not to jump in joy. Katsuki was alright.
As Bakugo moved to the back of the room, their eyes met. Kirishima's face split into a smile. He stared at the blonde with glee, waving at him as he passed. Bakugo didn't reciprocate the smile, but he did give a small wave and Eijirou could see the small gleem in the blondes eyes.
"Good to see you're alright Kat." Bakugo looked over to meet Mina's eyes. He scoffed and sat down at his seat. Kirishima watched as Midoriya began tapping morse code to check on Katsuki. The blonde tapped back to 'fuck off nerd'. Kirishima caught a glimpse of Izuku's relieved smile as he shook his head and focused on his notes again.
To be honest everyone was worried. When they heard that Kirishima hadn't seen the blonde or heard from him for so long, then he was late, they were all rightfully worried. Even the teachers shared concerned glances. But Kirishima couldn't focus anymore as he was busy staring at his boyfriend from across the room. 'He's safe. He's okay. You can question him later.'

Later in training Kirishima managed to get paired up with Katsuki. After being released to train he dragged Bakugo to the back of the gym and gave him a long hug. All his worries left him as the blonde sighed and hugged him back.
"I missed you! What happened? I heard you went to the doctors then nothing. Are you okay?" Kirishima moved to check Katsuki all over making sure he was okay. The blonde chuckled and pushed the red head away slightly.
"I'm fine thitty hair. Old hag made me get brathes. Said my snaggle tooth was a bother. It hurt a lot after I got them on so my old man made me stay in bed to rest." Bakugo had a deep red flush on his face from his new lisp. Kirishima immediately shot up and gaped at the blonde.
"Show me?" Kirishima's eyes were now glued to Katsuki's mouth. Bakugo rolled his eyes before opening his mouth slightly. Kirishima stared at the All Might colored rubber bands that covered his boyfriend's teeth. It was adorable. Always a fan boy until the end.
The more Kirishima stared the more he got curious. With a cautious look to the blondes eyes, Kirishima carefully reached a hand up and gently pressed it to Katsuki's back teeth. The other winced and pulled back. A glare set on his face. Meanwhile Kirishima was stunned by how much he liked that.
Kirishima flushed. 'What. The. Fuck. Eijirou. Don't be a creep!' Bakugo closed his mouth, raising an eyebrow at Eijirou.
"You okay there hair for brainss? What? Do they look that bad?" Katsuki raised a hand to cover his mouth. Kirishima snapped out of his dazed and flushed.
"No!" He yelled a bit too loudly. A few of their classmates looking over at them. Wincing he pulled Katsuki's hand away from his mouth. Holding it to his chest. He forced his mind to focus and gave his best smile to the shorter blonde.
"They look great Kat. I really like them. They suit you!"

Okay. Now. Kirishima was not a liar. He did think braces fit his boyfriend well. A little too well. And that fact was throwing him for a loop.
It's been three weeks since that day in the gym. Three weeks of talks, hangouts- three weeks of staring at Katsuki's mouth and getting a boner like it was their first make out all over again.
He can't help it! Eijirou can't explain it, but Katsuki with braces for some reason makes his heart race. Sure the blonde is more irritable now but hell if he wasn't pretty to look at. Kirishima spares a glance at the blonde across the room talking with Todoroki and Midoriya. Kirishima was seated at the kitchen island. The three boys talking behind the couches, in the common room, just within his view.
Katsuki's lips are swollen and cut from the new metal in his mouth. Bakugo is constantly licking his lips now. And when he grins or snarls you can tell his gums are red and inflamed. His cheeks are swollen from constant cuts. Eijirou shouldn't find this so attractive but...
'It probably hurts, I mean he winced when I touched them before. I bet his mouth is so swollen. His lips are so red, would he let me trace them? How wet is his mouth normally? Is it more wet now? I wonder if he'd let me feel them again. How would they look around-'
"KIRI!" Kirishima jumped back at the sudden yell. Falling to the floor with a thump. Groaning he looks up to see Midoriya above him. 'When did he get there? Shit did he notice I was staring?'
"Sorry! You just weren't responding I was getting worried. You okay?" Izuku offered his hand to the red head.
"It's okay man! Sorry, I was zoned out. " Eijirou took the offered hand as the shorter pulled him to his feet.
"No it's okay! I just wanted to check on you. You've been staring into space for a minute now." Midoriya looks concerned, but he had a knowing look on his face. 'Shit. He noticed.'
"I'm okay dude! Just a bit worried about Kats! His new braces have been bothering him a lot I've noticed." Smooth Kiri. Real smooth.
"Oh. Yeah he is a bit more irritated than normal huh?" Izuku sounded a bit surprised by the answer but says his response with a soft smirk on his face. But Kirishima doesn't see it as he tries to subtly search for his boyfriend. Key words 'tries' and 'subtly'.
"Maybe you could help him get some frustration out?" Kirishima flushed a bright red as Izuku broke into a loud laugh. Eijirou snapping back to face him. Eyes blown and blush spreading down his neck. The green haired boy had become more accustom to the jokes his friends make. Even picking up a few of his own. Still, it's always surprising when he uses said jokes.
"I'm joking- joking! But seriously, he goes to you for comfort. I'm sure that if you talk to him about whatever it is your worries will disappear. Kacchan is pretty direct with his wants and needs." Kirishima could only nod as the green haired boy giggled and walked away. 'That's easy for you to say.'
How is Eijirou supposed to talk to Katsuki about his 'issues without sounding insane'. 'Hey Kats- not to be a creep or anything but I want to shove my dick down your throat cause your new torture devices turn me on!' He'd sound crazy! Bakugo would blow him up for sure.
Kirishima groaned. He's living his own personal hell.

"What the fuck is your problem Ei." Bakugo stood with his arms crossed in the red heads room. Kirishima's head snapped up at the sudden intrusion.
Eijirou had opted to have a quiet night in instead of sitting through three hours of romcoms at Mina's sleepover. Katsuki had said he was going to train for a bit so he assumed he'd be asleep by the time th blonde came back. However here he is, standing in his doorway, pissed, and freshly showered. Kirishima sat up against his backboard, bewildered.
"Kats- what? Nothing- wait-" Katsuki locked the door behind him and moved to sit next to Kirishima. The blonde sat on the edge of the bed before shrugging and moving to straddle the other. Kirishima jumped but still moved to allow Katsuki get comfortable.
"Ei. You've been avoiding me for a week now. What's wrong." Kirishima flushed, hands instinctively moving to grab the blondes hips. Bakugo's hands moving to hold his shoulders. It took everything in him to not stare at Katsuki's mouth.
Kirishima didn't mean to, but as his strange fascination grew so did the amount of boners he got during class, training, interactions, hell even small glances In the hall! In order to combat this he started avoiding the blonde. In hind sight this was the mistake that definitely sealed his fait.
"Babe-" Mission failed. Kirishima is now staring at Katsuki's mouth. Bakugo raised his eyebrows before a light bulb seemed to go off in his mind. The blonde glanced down and rotated his hips slightly. Kirishima failed to hide the whine that left his mouth. Katsuki's eyes widened slightly.
"Shitty hair... Why are you hard?" His signature smirk finding it's way onto his face. Kirishima just stared at the blondes mouth, he could feel the blush on his face move to his neck. 'Fuck. This is not how I thought this would go.'
"Because you're really hot-" Bakugo's smirk widened. The red head wasn't ashamed. Just embarrassed that he was caught.
"You are! I don't know what you want me to say-" Bakugo slowly began rolling his hips, his hands holding Kirishima's shoulders for balance. Eijirou gasped and gripped his hips harder in an attempt to slow the blonde down.
"You've been avoiding me for a week, because I'm hot? Why is that now an issue?" The blonde tilted his head to the side. Forcing his hips down harder. Kirishima sucked in a breath. 'Now or never.'
"Idontknowwhybutforsomereasonifindyourbracessofuckinghotandicantlookatyouwithoutpoppingabonerandidontknowhowtomakeitstop!" Kirishima squeezed his eyes shut as he rambled on about his new found fantasy. Katsuki was slightly taken aback, but simply used his hand to tilt Eijirou's head up to meet his eyes. Kirishima slowly met his eyes.
"You think my braces... Are hot?" The amusement in his voice could clearly be heard. Eijirou's blush darkened impossibly more. He stared into the blondes eyes for a moment. Swallowing his pride as the blonde moved his hips to remind him to hurry up.
"It's just- your mouth is so swollen and- does it hurt? Gods it probably does- your lips are always swollen- and I just- fuck Kat." The blonde giggled and stopped his movements. Kirishima groaned and glanced up at him.
"Yes they hurt. But I'm more surprised that you've been avoiding me because you find them hot." Katsuki sounded a bit wounded but he clearly wasn't as upset as Kirishima expected.
"I'm sorry Kats. I just didn't know how you'd react... Can I feel then again? Please?" Eijirou did his best to not sound creepy when asking that question. Katsuki raised an eyebrow before snickering and moving to kneel next to the red head.
"Sure you weirdo if it means you'll stop avoiding me." The blonde opened his mouth and glanced at Kirishima waiting. The red head took in a breath before reaching up to Bakugo's mouth.
Katsuki winced as Kirishima pressed his fingers against his teeth. Feeling the metal and rubber bands. Kirishima stared as Bakugo's eyes glazed over and his mouth opened wider. Sliding his head down to take two of Kirishima's fingers into his mouth. The red head groaned at the sight.
Bakugo pulled back and down again. Bobbing his head. Kirishima pressed his fingers deeper into Bakugo's mouth. The blonde moaning at the action. Eijirou removed his fingers. Causing the other to whine. Kirishima gripped the back of Katsuki's neck and pulled him into a deep kiss.
Kirishima pulled Katsuki into his lap again as the blonde gripped at his shirt and hair. Bakugo began grinding as Kirishima's tongue explored his mouth.
"Wait! Eiji! Hold on!" Bakugo pushed away, holding Kirishima back with his arm.
"What- are you okay? What happened?" Bakugo chuckled and he moved to stand next to the bed.
"Calm down shitty hair. Sit on the edge I wanna suck you off." Kirishima flushed darker as he moved to sit on the edge of his bed.
"You don't have to Kat-"
"Shut up and enjoy your weird little fantasy." Kirishima promptly shut his mouth as Bakugo made his way into his knees in front of the red head. Taking his waistband into his hands and moving it down his thighs. Kirishima's breathe hitched at the sudden gush of cold air.
Reaching up Bakugo gently takes Kirishima into his hand and pumps a few times. Closely watching his boyfriends reactions through his lashes. Bending forward Katsuki sticks out his tongue and runs it along the underside vein. Kirishima groans softly at the touch. Bakugo watches Kirishima as he takes the tip and rubs it against his tongue and lips. Occasionally taking the tip fully into his mouth and sucking. The action causing Eijirou's hips to jump as he moans loudly.
Kirishima gently runs his hands through Bakugo's hair as he watches the blonde tongue at his tip. His braces on full display causing him to twitch in the others hold. Bakugo slowly takes Kirishima into his mouth, allowing his jaw to widen as he slowly bobs his head further down. Eijirou sighs at the feeling hand tightening in Katsuki's hair. Making the blonde moan softly. The vibrations sending a shock up Kirishima's spine.
Eijirou groans and grips Katsuki's hair as the blonde begins to bob faster. Moaning whenever his dick hits the back of the blondes throat. Slowly Eijirou tests the waters and rolls his hips. Watching the blonde closely for any discomfort. In response Bakugo braces his hands on Kirishima's thighs and slacks his jaw. Moaning as an indication to continue.
Kirishima grins as he shoves both of his hands into Katsuki's hair and holds him in place as he begins thrusting into his mouth. Moaning at the feeling of Bakugo swallowing around him. Meanwhile Katsuki's eyes rolled, drool dripping down his chin, his tongue trying to massage as much as he can. Moaning everytime the red head hits the back of his throat. Kirishima speeds up slightly, moaning as Bakugo chokes slightly.
"Fuck Kat- I'm close-" Kirishima groans as Katsuki opens his mouth as wide as he can. Eijirou's rhythm stuttering as he moans. Slowly his movements become erratic until he's holding Bakugo in place and shooting cum down his throat. Katsuki chokes as his nose is shoved into black pubic hair. Cum pooling in his mouth and throat. Kirishima rolls his hips and moans at the feeling.
Bakugo slowly pulls off swallowing everything he can. Kirishima stares in awe as cum drips from the blondes chin. His eyes looking glazed over and unfocused, tongue out slightly, throat bobbing as he swallows. He looks fucked out. Not to mention. His lips are swollen and his braces are covered in cum and saliva. Eijirou twitches. Blushing at the action.
"Kat? You okay?" Bakugo grins wildly, his eyes still a bit glazed. He climbs his way into Kirishima's lap.
"Round two?"

The two lay cuddling on Kirishima's bed as a movie plays on his laptop. Katsuki on the verge of passing out before,
"Do you hate your braces?" Bakugo sighs as he looks up at his boyfriend.
"Just be glad one of us enjoy them enough for the both of us." Kirishima chuckles and pulls Bakugo into a spooning position.
"Well, I love you more than any braces." He misses the grin that falls onto Katsuki's face.
"Yeah yeah. I love you too shitty hair."

*the next morning*
"Shitty hair! I have dried cum stuck in my braces!"
"Shit."
