Notes This will make the best sense if you've already read exsanguination but I guess you could read it on its own as well if you really want to. The door swung open hard enough that it bounced off the wall and came swinging back before Izuku could stumble, backward, over the threshold. Katsuki had one of Izuku’s hands in his and the other hand holding Izuku by the front of his black school uniform jacket. “Ka-kacchan,” Izuku panted out, “Our shoes.” “Uh huh.” Katsuki herded Izuku into the entryway, kicking the door shut with his heel. “What about them?” he asked as he herded Izuku towards the wall. Izuku rolled his eyes. “Off, offwith our shoes.” Katsuki pinned Izuku’s hand to the wall with his own and leaned in, whispering, “Yeah? And what else?” Izuku couldn’t answer immediately because Katsuki cut him off with a series of quick kisses. The whole walk back from the beach had been littered with them, but Katsuki’s fervor had only increased when they’d discovered the front door locked and had had to stop to unlock it. Considering it was the middle of the afternoon, there was only one reason they knew that Inko would lock the front door. They were alone in Izuku’s home. Pulling back when he had to get a full lungful, Katsuki smirked at Izuku. Izuku blinked, feeling dazed and warm and pleasant from his head to his toes. Katsuki reached up and trailed his fingers through Izuku’s hair. He wrinkled his nose and tugged on a matted curl. “You’ve got dried blood in your hair, Deku.” Izuku glanced to the side, “Do you want to… Want to help me take care of that?” Katsuki’s cheeks flushed red even as he teased Izuku by tugging his hair again, “Are you too shy to ask me to bathe with you? You? Mister changes in front of me, mister wears my clothes, mister sleeps in my damn bed whenever the hell he wants to?” “I-it’s different now,” Izuku said. “Right? Aren’t things different now because of… of us?” “We’re still best friends, aren’t we?” Katsuki asked. He slid his hand down out of Izuku’s hair, along the side of his head and to his neck. His callouses made goosebumps rise on Izuku’s skin. The pressure of his fingers, of his nails, on Izuku’s skin, made a shiver run down his spine. “The only thing that’s changed is we both know that we want more from each other than we want from anyone else.” “Right,” Izuku said, “We’re best friends.” He put his arms around Katsuki’s neck and asked, “So if nothing else has changed, we can still bathe together and everything?” “Uh huh,” Katsuki confirmed. He bent his head down and kissed Izuku, pressing him into the wall. Izuku could feel his heart hammering in his chest as Katsuki kissed him again and again. He had once believed he knew what it was like to be the sole focus of Katsuki’s attention, but Izuku was quickly realizing that he had had no clue before. Katsuki was as methodical about learning how to kiss Izuku the best way as he was in fully completely any task laid before him. From the movement of Katsuki’s tongue to the shift of his grip on Izuku’s nape, he tested what made Izuku’s body react the strongest. When Izuku could no longer stand on his own, Katsuki pulled back. His lips were slick and swollen from their kissing and Izuku couldn’t look away from them. “C’mon, idiot,” Katsuki said. His voice was rough; his breath uneven. The sound of it made the hair on Izuku’s arms stand on end. “Let’s get in the bath.” Izuku misplaced the time from the door to the bathroom. He knew that it contained them taking off their shoes and leaving their bags in his room. He knew it also contained another dozen quick kisses. But he set that time somewhere and completely lost track of it in his mind. He was the one to lock the bathroom door, partially out of habit and partially because he really, reallydidn’t want his mother walking in on them this time. And then Izuku stood there for a moment, staring at the door. In the corner of his eye he could see the mirror and in the mirror, he could see Katsuki pulling his shirt off. Slowly, Izuku turned to stare. He’d seen Katsuki strip down plenty of times before- at the beach, before bed, in the locker room at school and even before a bath. He’d watched and not said or done anything even though he’d wanted to so many times. Now he watched openly before swallowing and nerving himself up to act. Izuku crossed the space between them and slid his hand up Katsuki’s side. He ran his fingers over the soft skin and then the other boy’s ribs. All the while, he looked up to Katsuki’s face. Katsuki paused for a moment in pulling off his shirt but then finished shrugging out of the cloth and tossed it into the corner with his school jacket. “What?” Izuku shook his head. He brought up his other hand, palm flat against Katsuki’s abdomen and then moving up slowly. He felt the rise and fall of Katsuki’s breath and then his heartbeat when his hand was over the center of Katsuki’s chest. “It’s nothing, I just… It feels different. A little bit at least.” “What does?” Katsuki asked. He put his hand on Izuku’s wrist but didn’t pull his hand away. “I haven’t changed that fucking much since the last time you saw my chest.” “That’s not what I mean,” Izuku said. He retracted his hands, faltering for a moment. Unbuttoning his own clothes, he pulled them open and said, “You do it. See what youfeel.” Katsuki hesitated but Izuku was patient. He had to be, with Katsuki as his best friend. Sometimes Katsuki exploded into action and other times he took a bit longer to decide what he wanted to do. In the end, though, Izuku knew that Katsuki would do what he’d ask, as long as he didn’t find it moronic. His touch started light, just fingertips, skimming across Izuku’s skin. Katsuki’s fingers followed the muscle pattern of Izuku’s chest. As he reached the top, he pressed his palms against bare chest and slid them down. Izuku shivered down to his toes, his breath stuttering and eyelids fluttering shut. “Oh,” Katsuki said. His voice was a whisper. “Yeah.” Izuku smiled. Katsuki ran his hands back up, to Izuku’s shoulders. He slid them under the edges of his shirt and pulled the cloth down and off of Izuku. Tossing the clothes into the same pile, Katsuki took a step back to look at Izuku’s bare chest. “You never scar,” he said. “You haven’t scarred from a single death.” Izuku looked down at himself and then shrugged. “I don’t heal the normal way. When I get hurt I just reset my whole self and it regenerates. If I keep doing that, I might never scar.” Katsuki nodded. He gave Izuku one more look before he said, “I’ll start the bath.” He turned and went to the tub. “Okay,” Izuku said, “I’m going to get the blood off first.” He stripped out of the rest of his clothes. It was chilly in the bathroom, or at least, his skin felt strangely more sensitive than before. He watched as Katsuki fiddled with the faucet to get the right temperature for the bath- just this side of scalding. Stepping into the shower area, Izuku turned it on to wet his hair and wash out the blood. He closed his eyes, letting the water run over him and warm his skin. Opening them again, he watched as the blood swirled on the bathroom floor and to the drain. It wasn’t the first time he’d washed off his own blood. Some of his earliest experiments had left him so bloody he’d had to scrub it out from under his nails. “Here,” Katsuki suddenly said from very close. Izuku jumped as he looked up to see Katsuki standing behind him. “Sit down, Deku.” The command was a typical one, especially for their bathing time, but Katsuki’s cheeks were flushed. He’d been blushing more and more since they had kissed at the beach, Izuku noticed as he took a seat. He certainly liked the way Katsuki blushed but he wasn’t sure why it kept happening. Standing behind Izuku, Katsuki lathered soap in his hair. It was a familiar touch but that meant nothing when it still sent sparks down Izuku’s spine. He sat up straighter, mouth clamped shut, so he didn’t let out a noise. Katsuki’s nails scratched at his scalp, hitting all the points that made Izuku’s back arch against his control. Even the rinsing was somehow more intense, as Katsuki combed his fingers through Izuku’s hair to help the water clean it out. Izuku closed his eyes and tilted his chin up to help. The water pulled away. Katsuki’s hand slid up his throat and cupped his chin. Katsuki tilted Izuku’s head back a little more and to the side. Izuku managed to open his eyes just in time to see Katsuki bend down to kiss him. He held tightly onto the stool to keep from falling because of the angle. He didn’t want to stop kissing Katsuki because he fell off. “The water’s ready,” Katsuki said against his lips. “Are you?” Nodding in agreement, Izuku let Katsuki pull him up. He walked over to the bath feeling warm already, while Katsuki turned off the shower behind him. Izuku let out a little hiss as he got in the hot water. It began to relax his muscles the longer he was in there, though. Katsuki climbed in after him, sighing as he settled in the water. Izuku automatically leaned against the opposite side of the tub, facing Katsuki, like he usually did. He lay his head against the outside, closing his eyes as he relaxed. Katsuki, on the other side, sank down to his chin. For a while, they soaked in silence, doing nothing more than enjoy each other’s company. The water was too hot to think or to move and so Izuku sat there with a smile. As it began to cool, however, he felt a ripple on the water’s surface. Peaking open an eye, Izuku caught Katsuki getting up to his knees. Katsuki froze when Izuku looked at him and then, slowly, continued to move. He was crawling forward through the water, heading towards Izuku’s side. Izuku’s heart began to race the closer Katsuki got. He lifted his head and watched as Katsuki came to a stop in front of him. Without thinking much of it, Izuku spread his legs so Katsuki could inch closer. Then he reached for his friend and pulled him in. Again, it didn’t seem to matter how many times before their bodies had touched in the bath. Each brush of skin to skin was like an electric charge. Izuku had felt that way before, a time or two before, when he couldn’t help but notice Katsuki’s body and how much he’d wanted to touch him, but this was different. This was Katsuki looking at him intently. This was Katsuki’s hands under the water, lifting Izuku’s legs so he could find a comfortable spot. This was Katsuki who knew Izuku wanted him- a Katsuki who wanted Izuku as well. “Kacchan,” Izuku murmured as Katsuki leaned in against him. “Kacchan, please,” his hips moved up of their own volition. If Katsuki was at all uncertain about what Izuku wanted, he didn’t seem to show it. Nor did he bother to ask. He closed the distance between them and began to kiss Izuku. He’d already gotten better than those first kisses on the beach, while Izuku felt he could barely keep up. Izuku wrapped his arms around Katsuki’s shoulders and his legs around Katsuki’s hips. As he pulled Katsuki closer, the kisses got more intense and left them both breathless. Katsuki rocked against Izuku, slowly at first, until he found the angle that made Izuku’s head tilt back. “There,” Katsuki muttered to himself, “Like that.” He ground against Izuku harder. Their cocks rubbed against each other with each press of Katsuki’s hips. Izuku groaned, unable to keep silent since Katsuki wasn’t kissing him anymore. Instead, Katsuki’s mouth was at his throat and then lower, at the junction of his neck and his collarbone. He panted, his breath hot on Izuku’s flushed skin. “More?” Izuku asked, his fingers curled in Katsuki’s hair, “Kacchan?” Katsuki grinned at him. He too was flushed red across his cheeks and ears. His hair was damp and tangled, though not as badly as Izuku’s. He moved one hand from Izuku’s leg, that held him in place, and said, “Yeah okay. I’ll give you some more.” Izuku bit his lip, hard, as Katsuki’s hand wrapped around his cock. His hips bucked up into that touch, desperate for more. “Gimme your hand,” Katsuki demanded while he stroked. Dazedly, Izuku complied and untangled one hand from Katsuki’s hair. Katsuki pulled it down under the water and put it on his own cock. “There,” he panted, closing the distance to Izuku’s lips again, “Now we can take care of each other.” The next kisses were bruising and biting. Izuku’s attention fluctuated from Katsuki’s teeth digging into his lips to Katsuki’s hand pulling at his cock. Nothing else mattered in the world but what Katsuki was doing to him and what he was doing back. They rocked together in the water of the tub, sloshing it back and forth in their eagerness. Between two kisses that threatened to steal Izuku’s breath away, he gasped out, “Kacchan, I’m gonna-” Katsuki cut him off with the kiss. His hand moved faster. Izuku’s back arched and he came with a muffled cry. Sagging back against the bath wall, Izuku blinked up at Katsuki. He was met with a burning red stare as Katsuki let go of Izuku’s cock and began to work on his own. Izuku squirmed a little under the attention. His eyes kept glancing down to the water, where he could see Katsuki’s hand at work. Suddenly, Katsuki leaned in and kissed him hard enough to break the skin of his lip with his teeth. Izuku let out a little gasp, tasting his own blood, and that’s when he felt a shudder run through Katsuki’s body. When he was spent, Katsuki’s body went limp and he lay heavily on Izuku. Izuku held him, not minding the weight, and smiled when Katsuki pillowed his cheek on Izuku’s shoulder. Izuku closed his eyes, enjoying the embrace. They didn’t say anything, nothing needed to be said. Izuku could feel Katsuki’s breath evening out and his own heart rate was slowing down. The water was gross, sure, but they could rinse off again afterward. It wasn’t as though they hadn’t gotten blood on each other before. What was a little semen? What mattered the most, in Izuku’s opinion, was the way Katsuki trailed a fingertip over the thin skin of Izuku’s throat. Not mindlessly, not in a meaningless pattern, but a phrase. He moved his finger slowly at first, so Izuku could catch on. I love you.Katsuki’s finger spelled out. Izuku smiled and held on a little tighter.   ===============================================================================   Inko came home with the groceries to find the boys napping on the livingroom couch together. Katsuki was on the outside of the couch, facing Izuku, with an arm around him. Izuku was curled up, his head tucked under Katsuki’s chin. It was a sweet sight, looking at the way Katsuki lay protectively by Izuku’s side. Or at least, that’s what it looked like to her with the way he took the most dangerous position and how Izuku kept so close and safe. Two years ago, she never would have believed it possible for Katsuki to change his ways. Now, she smiled and shook her head at catching them napping before she’d even made dinner! “They must be exhausted from the exam,” she murmured to herself as she went into the kitchen to cook. “I’ll let them sleep a little longer. They’ll need all they can get before they get into Yuuei.” Not for one second did she doubt that they had gotten in. Her Izuku? With Katsuki there to help him? Well, nothing could stop her son if he had Katsuki and her support behind him, not even his quirkless history. Please drop_by_the_archive_and_comment to let the author know if you enjoyed their work!
