Work Text:
Kirishima knocked on Bakugou’s dorm room and waited patiently. It wasn’t too late so he wanted to know if his friend wanted to watch something. Third year was kicking their ass and it was important for them to have some downtime too. He could hear Bakugou inside talking to someone, but he wasn’t sure who was there, he couldn’t hear anybody else. Knocking again he called out.
“Bakugou! It’s me, can I come in?” He called and Bakugou called back telling him to hurry up already. He smiled and let himself into the room, closing the door behind himself.
“Hey bro do you want to wa-what’s…?” He trailed off when he noticed Denki on all fours between Bakugou’s legs, and what was definitely his dick in Denki’s mouth, all the way down, surely in his throat. His cheeks reddened and his dick gave an interested twitch. He was frozen by the door, and Bakugou barely looked up from the book he was reading. Kiri could barely make out what book it was because he was too busy watching Denki squirm under the new pair of eyes on him.
“Oi, if you want to listen then come sit down.” Bakugou motioned for him to come sit on the bed across from where they were situated. As he sat down confused but interested for sure, he was finally able to recognize that Bakugou was reading out loud the book Present Mic had assigned them for English class.
Bakugou continued reading as if Kiri hadn’t just walked in on his friend giving his best friend a blowjob. That’s what this was right? Kiri couldn’t help but let his eyes roam all over Kirishima’s body. He was still in his clothes, but the tight pants he wore left little to the imagination and simultaneously did wonders for his ass. His cropped shirt showed how much his abs twitched, from holding still. When he got up to his face, he could see that the boy was blushing like crazy, looking over at him as best he could without moving his head. Now it was Eijirou’s turn to blush like a schoolgirl. Bakugou turned the page and kept reading, Kaminari was struggling to stay still and eventually half way down the page Bakugou stopped and startled them both.
“Oi! If you don’t stop moving you don’t get to come.” He snapped and Denki whined around him. Bakugou only tightening his grip on the book. The only indication that he was actually feeling any of this. Nerves of steel Kirishima figured. He was about to start reading again and Kirishima couldn’t stop himself from speaking without giving it a second thought.
“I-uh I can help keep him still if you want.” He spoke and both of them turned to look at him, as well as Denki could turn his head that is. Bakugou raised an eyebrow at him and then rolled his eyes.
“Alright, well come on with it then Shitty hair.” He said and watched carefully as Kirishima moved cautiously behind the boy, placing his hands on Denki’s hips and settling his own firmly against the boy. Denki could feel Kirishima’s dick through their pants and he moaned around Bakugou, looking up to plead with him to continue reading. He knew that the only way he would get to finish is after Bakugou finished reading this chapter.
Eijirou bit his lips and watched Bakugou trying his hardest to not look down at where their hips were connected. He focused instead on where in the story Bakugou was. He listened and for a moment recognized the part they were at, and was able to follow along fairly easily. Until they got to the end of the chapter where Kiri hadn’t yet gotten too, and he found he was also restless, trying his best not to squirm around while he kept the other boy in place while he thought about the story. The chapter ended on a cliff hanger and when Bakugou set the book down both boys let out a whimper.
“Dunce face can only concentrate when there are high stakes, like getting to come. It also helps if he has something to focus on to keep his body busy, like a cock to suck on.” Bakugou said to Kiri as if Denki wasn’t right there, listening to everything they were saying.
“If you want you can join in. Sure your grades could use the help also.” Bakugou smirked and Kirishima nodded so fast he didn’t even have time to process it. Anything to get to come back and do this again.
When Kirishima looked up at Bakugou he let himself enjoy the view of Kiri trying to so hard to be good without even being aware of what he was doing. Like a puppy wanting instruction, so he gave it.
“Go ahead and pull his pants down, he’s probably already prepped.” Denki moaned at the comment and Bakugou let his fingers roam into his hair and bucked his hips up, making the blond choke and arch his back. That had Kiri bucking his hips also, grinding his dick against his friend. He went to grab the waistband of his pants, hesitating then for a moment. He realized he never really asked his friend if it was okay to be touching him. Bakugou, sensing his hesitation, gave Denki’s hair a pet as he spoke up again.
“Don’t worry, Spark-plug here has been dreaming of the day one of you extras come and join in.”
“Is that right Denks?” Denki bobbed his head over Bakugou’s dick to makeshift nod, making Katsuki curse and grab his hair again with a vicious grip. With his new consent granted he reached around the boy and undid his buttons and pulled his pants down with one motion. They all groaned and Katsuki was right, sitting there between his lovely little cheeks was a simple silicone plug base. It was yellow, and Kirishima would have laughed, but it wasn’t funny, it was so hot. He didn’t think it was possible for more blood to rush to his dick. Eijirou grabbed his ass cheeks and used his thumbs to push on the plug. Bakugou finally let the boy come up for air, letting a moan escape his mouth as soon as he could.
“Fuck…Kiri…” He panted and looked back to the redhead, they locked eyes for the first time since they started, and he wanted to move on instinct, but he remembered who else was here, and as little as Kirishima knew he could pick up on the dynamic pretty quickly. He looked up to Bakugou for permission and when the blond nodded, Eijirou was pulling slowly on the plug, and after some initial stretching the toy came out relatively easily. His hole looked so inviting… Kiri had never thought he’d be so down to stick his tongue in someone's ass, but seeing Denki’s hole quivering under his gaze he just wanted to lick and suck over the hole undil Denki cried. He made a move to rub his fingers over the sensitive bud that was quickly closing back up, before Bakugou tutted and both of them looked up to him.
“You wanna fuck him?” Katsuki asked and Kiri nodded again.
“What do you say?” He asked as he shoved his cock back down Denki’s throat. He arched his back and his hole winked at Kirishima as he processed what Bakugou was asking, and fuck if that didn’t make him even harder.
“Please, please can I fuck him…” Eijirou whimpered and Bakugou pretended to ponder his question before he looked nearly feral when he agreed.
“Fuck him good Red.” Once the permission was given Kiri was undoing his pants so fast he nearly dropped the bottle of lube being thrown his way. After squirting some of it into his hand he pumped himself a few times, groaning and letting his head fall back. Finally he deemed himself ready, and lined up, looking to Bakugou once more, who previously had been muttering something to Denki for just them to hear, and it had Denki relaxing, when he looked up at Kiri he nodded, with a small grin on his face. Good, he was getting off on this too.
When he sank into his friend he wondered why the hell they hadn’t done this sooner. He bottomed out as Katsuki rocked his hips up and Denki mewled around the cock and his whole body shivered as he was thoroughly stuffed. Once things really got going they all knew it wasn’t going to be long before it was over, but fuck if it didn’t feel great the whole time. They took turns thrusting in, shoving Denki onto the other cock, they matched paces, and Denki was practically shooting off electricity with how tightly wound he was, just waiting for permission.
Bakugou moved forward, keeping Denki as far down on his cock he could get him, and reached for Kirishima who went willingly. Bakugou kissed him deeply, making him moan and falter his hips. Denki shivered once and then came without any touching or prompting from anything other than being so unbelievably stuffed full of his friends’ cocks. When Kiri pulled back he stuttered his hips and pulled out coming all over Denki’s lower back. Bakugou came down the boy's throat, and sighed, letting his head fall back as he eased Denki off his cock finally. Denki just fell onto the floor, too tired to hold himself up any longer. Once Kiri could function again he scooped Denki up and moved him to the bed, checking on him.
“You with us blondy?” Bakugou asked coming over to move some hair out of his eyes. When Denki smiled big and gave a nonverbal answer Bakugou nodded and looked over to Eijirou.
“How are you?”
“Me? I’m good, is he okay?” Kiri asked looked to Denki who wasn’t moving much.
“He’s floating right now, but he’ll be okay, he’ll fall asleep here and I’ll keep an eye on him. Are you gunna be okay to sleep on your own?” Bakugou asked as he leaned over to fuss over Kiri also.
“Yeah I’ll be fine.” He said, letting his friend do this. It felt nice to have Bakugou looking out for them.
“Okay good, next time I’ll get the air mattress and you can both stay here. And we’ll talk more about rules and safe words.” He said and ruffled Kiri’s hair before shooing him out so he could climb in bed also after cleaning up Denki.
As Kiri left he thought back to the book they had been listening to and suddenly was so excited for the next chapter.
