i don't date extras (kiribakukami)

Acceptance

Denki came out of the common shower, half brushing his hair, half singing into it, feeling as light and happy as he had ever been. It had been a good day. He didn't remember much of it, because he had spent it reliving Katsuki's kiss on his neck and Eijiro's kisses on his lips. He couldn't stop smiling and he felt BOLD. He walked back to his room just wearing a towel, finger guns pointing to whomever he went past by, saying "Hey, there" while he danced to a music that was just sounding in his own head. Things couldn't be more perfect. He opened the door to his room with the elbow while looking at his phone and pushed it closed with one of his feet.
He heard him before he saw him.
His eyes went up from his phone to Bakugo, who he found sitting in the nearest part of his bed, staring at him, his elbows over his knees, his hands in front of his face but not covering an intense look, all of his body pointing towards the door, menacingly, like a predator, he looked serious. Bakugo stood up and walked straight to Denki. The electric blond had no clue what was happening right now. He felt threatened, he thought for a second that maybe he had find out about Kiri kissing him and he had come to kill him. The palm of the explosive hero's hand slammed against the wood of the door, right next to Denki's head. He jumped, startled. Before he could say anything (which was quite fast), Bakugo pushed his body against the loud blonde's and against the door. Denki's head hit the wood hard when the explosive hero pressed his lips against his, aggressively, desperately. He kissed him like he would die or kill him. Denki melted, continuing the kiss, finding hard to do anything but follow his lead. Katsuki pressed his body against him, not leaving any space between them and as suddenly as he had started, he ended it. The kiss broke, the serious face and the fiery eyes filled with unsaid words stepped back. Bakugo opened the door, pushing him forward and out of the way.
"Fucking disgusting room", was the only thing he said before going out and slamming the door behind him, leaving Denki alone and surprised. Denki touched his own lips, still warm from Bakugo's touch, a dumb smile covered his face. God, this was the single hottest thing that had ever happened to him. He slid down the door, grinning like a dumbass and chuckled while falling to his side. God, that was hot.

Bakugo slammed the door to his own room, and then found Kirishima inside it. He clicked his tongue, his face flushing. He went to his boyfriend and kissed him aggressively too. Kirishima laughed after reciprocating his kiss, half hugged half tackled his boyfriend and threw them both on the bed.
"You are so cute when you get like that".
"Shut up", the angry Pomeranian barked. The redhead started passing a hand through the blonde hair, stroking upwards, just on the lower part of the back of the neck, the only place and form Bakugo accepted his hair to be touched. He was so adamant about his hair.
"I kissed him this morning", Eijiro told his boyfriend, he didn't need to say who. Katsuki looked at him, pissed. He wanted to bark at him for that. He couldn't, even if he felt kind of jealous for a second, his emotions too high right now. "It's nice having him around too, isn't it?", he kept on caressing his hair, still not releasing the trap he had done with his arms.
"Fucking annoying", Bakugo murmured against his chest, still made it sound like a bark.
"I would be happy to be a throuple with him", he was almost sure Bakugo wanted that too, but he couldn't count on his boyfriend to have an actual conversation where he used words right now, he was feeling too soft and vulnerable to dare to put his desires into words. What if everything went to hell? He wasn't even able to know what could go wrong or how, he was just mentally blocked. "And I think he would like that too. I mean... Would it be so bad? You know, waking up, the three of us. Kissing him. Spending time together..." Katsuki grunted, no word out of his mouth. "I love you, and you are more than enough for me... So if you don't want that, that's perfectly OK".
"I love you too", he was used to understanding him for what he avoided to say instead of for what he said, but this was too serious. He would have to find an opening in Bakugo's wall, there always was.
"I can back off if you're not OK with it. Do you want me to put some space between me and Denks?"
"No".
"Do YOU want to put space between you and Denks?"
"No", this one sounded like a kid being forced to apologize.
"Who would have known you were polyam too, huh?"
"Whatever. Still not poly", he huffed and puffed, still sounding like a kid. Kirishima decided to leave that conversation for a moment when he was ready.
"And he's poly too! We hit a jackpot", well, in fact Kaminari didn't consider himself poly. "Although knowing him is not that surprising..."
"Shut up already".
"Are you going to kiss him then?"
"I already did", that shocked him, but he grinned anyway. "Aaaw, so manly!" that sounded a lot like 'so cute'. "I wish I had been there to see it! Did it hurt?", he teased his boyfriend jokingly, knowing very well he was embarrassed because of that self-control failure. Bakugo pushed him. "And what did he say?"
"Shitty hair, you know damn well if I kiss, I kiss your brains out until you can't fucking talk", he sounded slightly proud of that. It was actually quite a fit to manage to leave Denki speechless, Kirishima had to give him that, he smiled tenderly again.
"I bet he had... A blast with Blasty".
"Eiji, what the fuck? God, such a bad pun", he muttered, way more relaxed now. Kirishima loosened his arms, giving his boyfriend space to run away if he needed to, now that he knew he didn't want to.
"Bet you... Blew him away".
"I swear to fucking God".
"Bet his mind is... exploding", Bakugo blasted a really small explosion right against his chest, his cheeks turned a deep pink and looking completely ashamed, so Kirishima decided he didn't need to torture him anymore. "I love you. You're the best. I'm so glad we can have him in common too. We should let him know, though". Katsuki grunted. "He already tried to run away yesterday because he didn't want to intrude, he could take months to understand we are together the three of us". Their only hope was for Denki to realize Bakugo was falling as badly for him as he had fallen for him and talk it through... It wasn't great.
"He's pretty smart, he'll figure it out", he grunted. Or maybe there was another option...
"Wanna bet?", he said, not expecting his boyfriend to fall for that lame try. The smile in Bakugo's eyes made him regret not specifying. He didn't wanted them to play with Kaminari's feelings, so he had to specify and fast. "Let's bet on how soon we can make him realize without literally saying the words", that was a good way to help Katsuki lower his barriers in front of him, Eijiro wasn't planning on saying anything else about their feelings to each other.
"Gonna fucking make him spell it", he answered, decisive. Kirishima smiled again, sometimes his competitive side was amazing.
