As soon as Bakugou allowed himself to be pushed against the back of the door and kissed until he couldn’t breathe, Kirishima knew he was in trouble. Even as he pulled away, the blond’s hand stayed deeply tangled in the mess of hair at the back of Kirishima’s neck, anchoring him in place.
Bakugou’s mouth found his again with savage intensity, pulling the redhead flush against him and squeezing. Kirishima sighed heavily into Bakugou’s mouth, earning himself a growl as the other continued.
Kirishima pulled himself away forcefully, though he didn’t manage to shake Bakugou’s hand. “Katsuki, take it easy…”
Bakugou glared at him darkly. “Fucking bite me.” And the blond wasn’t joking, Kirishima realized with wide eyes, as he yanked down the hem of his shirt collar, baring an alabaster skinned shoulder. Kirishima knew he was probably drooling, but he couldn’t really bring himself to care at present.
Bakugou guided his head to his neck, and it only took a second of hesitation before Kirishima went after the side of his neck, sucking and licking with abandon. Suddenly Bakugou grabbed his chin, roughly turning his face so he could look him in the eyes. “I thought I told you. To. Fucking. Bite. Me.” There was no hesitation whatsoever for Kirishima to heft the blond into his arms and haul him over to his bed, toppling down onto it with Bakugou on top of him.
Kirishima heard Bakugou’s shirt tear a seam as he practically ripped it off, flinging it across the room. The blond laid down and grabbed the sides of Kirishima’s shirt, forcefully pulling him down on top of him, nearly winding the redhead in the process as they aligned, chest-to-chest and hip-to-hip.
“Shit,” Kirishima wheezed, “Easy! I don’t want to hurt you, you know.”
Bakugou grabbed his neck again and crushed their lips together. “Shut the fuck up.” The blond hiked his knees up to either side of Kirishima’s hips, the hand that wasn’t at his neck slipping underneath his shirt to trace up his spine. Kirishima shivered and pulled away to find Bakugou’s neck. Said male growled impatiently, “Hurry the fuck up.”
Kirishima needed no second bidding. He sank his teeth into the spot he had been abusing earlier, dragging a moan out of Bakugou in the process. “Fucking harder.” Bakugou’s thighs were squeezing his hips so hard Kirishima was convinced he was going to bruise, but he bit down harder, his hands running up and down the blond’s sides. He didn’t stop until the taste of blood startled him back to his senses.
He tore his mouth from Bakugou’s neck, staring down in shock at the bloody ring of punctures his teeth had inflicted. Bakugou was breathing heavily, snarling up at him. “The fuck you stopping for, cockmunch?”
Kirishima quirked an extremely confused eyebrow at him. “You don’t have any ideas?”
Bakugou growled, and Kirishima brushed the back of his hand across his mouth. He blanched at the amount of blood that came off, turning his questioning gaze to Bakugou’s, only to find him avoiding eye contact.
“Katsuki,” Kirishima began somewhat hesitantly, “Do you…like that?”
Bakugou was strangely silent, and Kirishima could only think of one reason why, his stomach twisting into an uncomfortable knot. Hoping to prove himself wrong, the redhead gently pushed one of his thighs into Bakugou’s crotch, frowning at how the blond tensed. His gaze darkened.
“Katsuki, what the fuck. You’re not even fucking enjoying this, are you?”
Surprised by the profanity coming from the redhead, Bakugou looked up to meet his eyes, quailing minutely at the expression he was met with. Confusion, anger, hurt. Bakugou scowled as hard as he could and looked away again, but this time it was Kirishima who grabbed his chin, though far gentler, to look at him again.
“What the hell has gotten into you? You oughta know that hurting you is the absolute last thing I want to do, so why encourage it if you’re not enjoying it?”
Bakugou didn’t say anything at first, just reached up and laid his hand over Kirishima’s, expression lost. It didn’t take long for Kirishima to sit up and bring Bakugou with him, sitting with the blond in his lap, using the edge of one of his bedsheets to gently dab at the blood still seeping from Bakugou’s neck as he waited.
Bakugou sighed hoarsely, resting his chin on Kirishima’s shoulder. “I thought that maybe I’d like it. Make things easier.”
“Easier?” Kirishima echoed, realization dawning as he pried Bakugou away to look at him. “Have I told you today how much I love you?”
“Wha-. What the fuck?” Bakugou’s eyebrows furrowed, irritated at the seemingly random announcement.
Kirishima leaned forward and knocked their noses together, getting an impatient sigh for his efforts. “I love you. What I need is you. Nothing else. Anything else is a want, and I can live with that. That includes sex.”
Bakugou flushed darkly, huffing, “Fuck, that sounds lame as shit.”
Kirishima finally cracked a smile. “Doesn’t mean it’s not true.” Kirishima kissed the unhurt side of his neck, and Bakugou’s fingers curled into his hair again.
“Hey, shitty hair.”
Kirishima hummed and blinked up at the blond.
Bakugou shifted and glared at nothing in particular. “We can keep going, you know.”
Kirishima surprised him by vehemently shaking his head. “I’m not doing shit unless it’s what you want.”
Bakugou scrunched up his face in a grimace. “I have to say it?”
“Yes!” Kirishima yelled, reaching up to pinch both of Bakugou’s cheeks, “Welcome to the wonderful world of consent, you dipstick!”
“Get yer fuckin’ hands off my face cockmunch! Fine, fine, I’m sayin’ it, yes!” There was a blush high on his cheeks and he added with a huff, “Besides, this shit’s a lot easier when it’s with someone I trust.” He felt Kirishima’s gaze on him and bit his tongue, glaring off to the side.
Kirishima was suddenly struck with a fit of the giggles. Grinning like a madman, he managed to get both himself and Bakugou howling with laughter, though on Bakugou’s end it could be more attributed to the ferocious tickling he was employing. Kirishima just couldn’t help himself; Bakugou laughing was easily one of the most wonderful things life had ever blessed him with, and he wanted to hear it as often as he possibly could.
Eventually, Bakugou cut him off mid-chuckle with a slow kiss that left the redhead’s cheeks warm and his heart happy. This was probably as calm as Bakugou would ever get, and Kirishima basked in the quiet affection of the kiss, humming happily.
When they pulled away, he maneuvered Bakugou onto his side, laying down beside him in the same position after discarding his shirt, and pillowing Bakugou’s head with his arm. The blond huffed, but ran his hand up into spiky red tresses, softly scratching at his scalp as he leaned in to initiate another kiss.
Kirishima had come to find that, as much as he gave voice to the contrary, Bakugou appreciated it when he held him close. With Bakugou mostly distracted, Kirishima ran a hand up the side of his chest, flattening his palm over the back of his shoulder and curling his arm around him, pulling him so they were pressed together as close as he could get them. Bakugou sighed into his mouth, eyes fluttering closed, and Kirishima was more than relieved to find that Bakugou was enjoying it more this time around, when their hips came to rest against one another.
Using the hand beneath the blond to keep their contact, Kirishima trailed his other hand to the hem of Bakugou’s pants, where he waited for approval. After a few moments, Bakugou seemed to finally notice and snorted. He surprised Kirishima, however, by reaching forward and tugging down the zipper to his jeans, his eyes now open and not leaving the redhead’s during their kiss.
He paused only for a moment, for the other’s nod, then he slipped his hand into Kirishima’s underwear, stroking him slowly. Kirishima gasped then chuckled against Bakugou’s lips, earning a glare and a stilled hand, but he just peppered the blond’s cheeks with kisses until he continued.
It didn’t take long for Kirishima to still his wrist, placing a last kiss to his lips before he was moving downward to his chest. He kissed the front of Bakugou’s neck before he moved down to his collarbone and the muscles of his chest.
“Katsuki…” He murmured against his skin. Bakugou hummed in question, and Kirishima grinned up at him. “There’s no one as manly as you, dude.” He accompanied this with a kiss between Bakugou’s pectorals.
Said blond rolled his eyes as hard as he could. “And no one but you could possibly make this situation any gayer than it already is.” So he said, but there was considerably less malice embedded in his words than most other times.
Kirishima laughed and continued his kissing, all across Bakugou’s chest and stomach. When Bakugou had had enough and pushed at his shoulder, Kirishima cracked a smile at him and dipped his hand into the blond’s pants from where it had been resting at the hem since he started.
Bakugou sighed in relief, pushing himself into Kirishima’s hand as the redhead began to stroke him. Kirishima kept up with his kisses and nips, anywhere that he found a reaction.
He came to find that Bakugou did indeed like neck stimulation, just of the gentler kind, much to the surprise of them both. Bakugou gasped at a particularly successful venture to find his pulse point, and ended up with his hand back down Kirishima’s pants. Kirishima groaned and moved up to suck gently at the spot below his ear, planting wet kisses across Bakugou’s cheek afterwards.
The blond himself nudged Kirishima’s head next to his, so he could better kiss him, and they both pressed into one another, hungry, but no longer out of control.
Bakugou’s release crashed over him only seconds before Kirishima’s, and he was rather surprised by the real pleasure that replaced his usual indifference when it came to occasions such as now.
They laid together, catching their breath, for a few minutes after before Kirishima grabbed his shirt from the floor and cleaned the both of them up as best he could. He tugged Bakugou into his arms, noting how docile, and charmingly adorable, he was when he was sleepy like this.
The blond was breathing evenly already, it wouldn’t be long before he was asleep, so Kirishima pressed his lips softly to his forehead and held him close as he drifted off.
Kirishima was unsure whether Bakugou heard his, “I love you.” While he was awake or not, but then again, waking or dream it was true, so he supposed there wasn’t much to worry about.
