Work Text:
There were hurried hands moving all over Izuku’s body as if they couldn’t get enough. He was pressed against the door, making it difficult for him to do anything but just hold the other man back in the same desperate need. The hands moved under Izuku’s shirt, caressing his sides, his back, his shoulders, everywhere, as if they were looking for more. It was driving Izuku fucking insane. He broke away from the kiss to stare at darkened red eyes that were looking at him as if they were challenging Izuku in a way that was making him more turned on than ever.
“Bed,” Izuku breathed out, feeling something tight unfurl in his stomach at the implication he had just made.
Kacchan smirked and Izuku just about lost it. He grabbed the blond from the collar of his shirt and pressed their mouths together once more, kissing Kacchan hard and pulling at his hair a bit. He heard the other man make a sound that went straight to Izuku’s groin. Before the blond could say anything else, he separated from him once more and almost dragged him to his bed, pushing him as soon as the back of Kacchan’s legs touched the mattress. Izuku climbed over Kacchan’s lap and ran his hands over the other man’s clothed chest, enjoying the feeling of strong muscles against his palms, wanting to do it for hours and hours.
“Off,” He ordered, pulling at the hem of Kacchan’s black tank top.
“Who are you, and what the fuck did you do to Deku?” Kacchan said with a teasing smile, helping Izuku remove his shirt anyway. Izuku felt his cheeks get warm and his hands faltered for a few seconds on Kacchan’s chest, wondering if maybe he had gone too far. Maybe Kacchan wanted to just make out? They had certainly never gone this far before, always stopping before things got too out of hand. Izuku’d thought that Kacchan wanted this, given the fact that a few seconds ago his hands were all over Izuku too, but maybe he changed his mind? Maybe he realized that he didn’t want to do this with Izuku anymore? He wouldn’t really be surprised if that were the case-
“Nerd,” Kachan said, interrupting Izuku’s jumbled thoughts. The blond reached out a hand and cupped Izuku’s cheek in his palm in a such a gentle touch that might look out of character for anyone that didn’t know Kacchan like Izuku did. It made his heart clench with love. “I like it,” He said quietly, pulling Izuku’s face closer to his own, ghosting his lips over Izuku’s. “It’s hot,” He whispered against his lips before kissing him, biting at Izuku’s lower lip with a painful slowness that was gonna kill him at any point now.
He suddenly couldn’t wait to be touching Kacchan all over, to be pressed against him, to be close, closer. He broke away to take off his own shirt and gasped when Kacchan’s hands moved immediately to touch his abdomen, moving up and down his chest. He bit his lip to suppress the sounds that were fighting to escape his mouth because it felt good. It felt so good to be touched like this, but it felt better to know that it was Kacchan the one who was touching him. It was driving him crazy.
“Fucking nerd,” Kacchan let out in a shaky breath, running both hands over Izuku’s biceps, his eyes fixed on the muscles there. “Who would’ve thought that skinny little Deku would get so fucking ripped when he got older?”
Izuku chuckled. “I’ve worked hard, Kacchan.”
Kacchan looked up, eyes locked with Izuku’s. “I know,” He muttered back quietly, suddenly looking more serious than before. And Izuku knew what that look meant. It was Kacchan beating himself up about things from their past that they couldn’t change but that Kacchan was never able to leave behind. Izuku shook his head and bent down, kissing the corner of Kacchan’s mouth before moving down his jaw and neck, leaving kisses all over. This wasn’t what this night was about.
“If you’re still thinking then I’m clearly not doing a good job here,” He muttered against Kacchan’s ear, before kissing it lightly, moving down to suck on Kacchan’s pulse point, trying his hardest to leave a mark there. He wasn’t exactly experienced on hickeys, but he hoped he was doing okay. If the gasp that came out of Kacchan’s mouth was anything to go by then he wasn’t half bad.
Kacchan’s hands suddenly moved to grab his face, and he was pressing their mouths together roughly but also desperately. And then he was flipped onto his back, with Kacchan straddling his lap and staring down at him with hungry eyes.
“I’ll show you, Izuku,” Kacchan whispered close to his mouth, saying Izuku’s name in a way that made his already hard dick throb painfully in his boxers.
“K-Kacchan,” He gasped, when Kacchan moved to lick his chest, kissing one of his nipples. One of his hands was moving down Izuku’s stomach and under his pants, palming the hardness of his boxers, making Izuku groan in an embarrassingly needy way. His hands went immediately to Kacchan’s arms, trying to steady himself but he was so turned on it was almost impossible. Kacchan moved again and now he was kissing him hard, one hand grabbing Izuku’s cheek and the other touching Izuku’s groin in painfully slow movements.
“Katsuki,” He said again, breathless in between kisses. Everything felt so good, he couldn’t control the way his hips buckled up, or how his eyes shuttered closed from pleasure or how he was gripping Kacchan’s arms. He vaguely wondered if Kacchan could tell by Izuku’s obvious excitement how inexperienced he actually was but couldn’t really focus on that when Kacchan’s hands were touching him just right.
And then, Kacchan’s hand was moving under Izuku’s boxers, and he just couldn’t take it anymore. He groaned in pleasure, feeling like there were stars behind his eyes, and squeezed Kacchan’s arm in an attempt to calm himself but what happened instead was the feeling of something snapping under his fingers that made him froze immediately, opening his eyes in terrifying dread as he heard Kacchan make an uncomfortable sound. Kacchan was looking down at him with wide eyes and a weird expression on his face and his complexion was turning green every second it passed.
“Did I just-”
“It’s okay,” Kacchan groaned, moving away of Izuku’s lap, and immediately falling to the ground on his knees, cradling his left arm with his hand.
“Did I just break your arm?!” Izuku asked horrified as he scrambled up from the bed to go with Kacchan, hands hovering over the other man, unsure of what to do.
“Yep,” Kacchan grunted, letting out a controlled breath. “Yep, feels pretty broken to me.”
Izuku couldn’t say anything for a couple of seconds, wide eyes fixed on Katsuki’s left arm that was starting to look purple and bent in an unnatural way. Izuku finally blinked and felt how his eyes were starting to get watery. He quickly looked away from Kacchan, not wanting him to notice how he might start to cry, and started to look for their discarded shirts but messing it all by forgetting where they had ended.
“We need to go to Recovery Girl,” Izuku said frantically, throwing pillows and blankets all over his room.
“Deku–”
“We need to hurry or it’s gonna hurt worse,” He said panicked, and tried to look for Kacchan’s shoes too, trying to be useful in some way after he had ruined it all. “D-does it hurt a lot?” He asked, and his voice came out shaky and pathetic and he wanted to punch himself for being like this.
“Wait, shit, Deku, don’t- don’t cry on me, idiot!” Kacchan said from behind him, and Izuku felt his cheeks get warmer at the fact that he was being so obvious. “I’m the one with the broken arm, you’re not supposed to be the one that’s crying!” Kacchan said, sounding frustrated but also concerned for him, and that just made him feel so much worse.
Izuku turned around, staring at his boyfriend sitting on the ground, looking like he was in pain but also like he was worried for him after breaking his arm. He felt mortified and so utterly stupid.
“I’m so sorry, Kacchan,” He said weakly, and the tears finally escaped. “I didn’t notice my quirk had activated, I’m so stupid!” He said as he aggressively wiped his tears. “I- I ruined everything.”
“Deku-”
“We need to take you to Recovery Girl,” Izuku interrupted quickly, turning around and finally spotting his missing shirt. He put it on and started looking for their shoes.
“Izuku!” Kacchan said loudly with an irritated tone, and he jumped, turning around to look at Kacchan’s angry glare and feeling startled by the use his first name. “Stop being stupid! It’s just a broken arm, I’ve had fucking worse! So if you don’t stop freaking out right this second I might consider not coming back here to finish what we started, alright nerd?!” Kacchan finished with an impassive voice that left Izuku feeling stunned for a few seconds.
And then there were tears falling from his eyes again and Kacchan was groaning, either from pain or frustration, Izuku wasn’t sure.
“Come on, Izuku! What is it now?” He asked, his voice coming out tired and breathy probably due to the increasing pain of his broken arm.
“I-I’m sorry,” Izuku said, openly crying as he knelt in front of Kacchan and held his right hand, the one from his uninjured arm, carefully. “Does that mean that you still want to be with me… after I-”
“Of course, you nerd,” Kacchan answered, rolling his eyes but looking at him with a hint of amusement in his eyes. “You think a few broken bones are gonna scare me away? If that were true, I would’ve stayed away from you ever since that first month at UA,” Kacchan said gentler and Izuku felt such warmness fill his heart, in a way only Kacchan made him feel and a few more tears fell from his eyes.
“I love you, Katsuki,” Izuku said, taking a deep breath and squeezing Kacchan’s hand, trying to convey just how much he really did love him.
Kacchan’s cheeks got redder and Izuku smiled, leaning down to peck his cheek quickly.
“Yeah, yeah, I love you, too,” Kacchan said dismissively, averting his eyes from Izuku, clearly a bit flustered by his words. “You better come up with a good excuse that also explains why I don’t have a shirt.”
Izuku grimaced.
“Crap,” He muttered, and he saw Kacchan smirk before it quickly turned into a grimace.
“Can we go now?” He asked, pain evident in his voice.
Izuku nodded quickly and helped Kacchan get up from the floor. After the blond had his shoes back on, they were on their way to the door but Kacchan stopped him before they could leave Izuku’s room, harshly grabbing onto the front of his shirt and kissing him hard and quick.
“Right were we left off, nerd,” Kacchan muttered against his lips and Izuku immediately felt a throb of arousal go through his body.
He swallowed and nodded quickly, a smile on his face.
“Yes, Kacchan.”
