Kirishima stood in the bedroom casually cleaning, earphones plugged in and listening to music. Kirishima takes at least one day every week to clean the rooms, mostly to save Bakugo from scolding him and cleaning it himself.
At somepoint kirishima started to hum, which soon escalated into softly singing along, into now, when he was singing aloud proudly. Kirishima was a great singer.
However, he hated hearing his voice so he wouldn't sing often. But one time Mina had caught him and soon the other girls found out and insisted he develop his singing. Thankfully it was only them that knew, Kirishima didn't know how he would deal with the whole class knowing. Hell, even the entire school!
But... in the house he could relax. He didn't have to worry about shoji next door or Kaminari below. Or Mina, across the hall, who already knew so it was no biggie.
Kirishima soon got lost in the music while cleaning, doing more dancing and theatrics as time passed quickly. Kirishima got to one of his favourite songs. One of the songs he knew like the back of his hand and Mina said he sung the best. But that could just because she's his friend.
He was so entranced he didn't hear the front door open. He didnt hear the footsteps and the stall. He didn't hear the soft curse.
He didn't hear the room door open.
Kirishima cracked open his eyes, goofy smile as he still sung away. His eyes landed on the figure at the door and he froze imideitly, stumbling as he fumbled over his words.
Bakugou stood there staring at Kirishima, "that was you?"
Kirishima took out his earplugs and stood straight, "um... yeah...." his face was reder than his hair.
Bakugou smirked, "I didn't know you could sing so well. Why don't you ever sing for me?" He stepped into the room, "you keeping secrets from me, Ei? I'm disapointed..." he said softly, mocking a sad tone.
"I... I thought you didn't finish until five?..." Kirishima asked, "yeah? Look at the clock, Ei." Bakugou pointed to the bedside clock which read '5:12'. Kirishima looked back to Bakugou, "I guess I got lost in the music.." he gave a small giggle.
Bakugou's smirk softened, "seriously. When were you gonna tell me you were a good singer?" Kirishima rubbed the back of his neck, "I don't know, I didn't really see it as relevant."
"Relevant? You sounded amazing, Ei, you should have told me you had a great talent." Bakugou placed his hands on Kirishima's hips and held him close. He leaned in and gave Kirishima a kiss, hard but sweet.
Kirishima closed his eyes and placed his forehead against Bakugou's when their lips parted, "I'll keep that in mind."
Bakugou scoffs, "you better. I want to know everything about you, baby. Especially if it shows how manly you are." Bakugou smiles softly as he says the last part knowing it would make the redhead happy.
(If you prefer to keep this story fluffy, just end here, the next part is suggestive)
Kirishima gives a grin back, the soft moment doesn't last too long before Bakugou is pushing Kirishima onto the bed and crawling over him.
"Show me what else you can do with that mouth hm?" Bakugou grins, leaning down to nibble kirishima's ear "I want you to sing for me."
