Chapter Text
Their first time sharing a bed was awkward. To be perfectly honest, it wasn’t actually their first time. As children they had shared a bed plenty of times, even showers and baths. But this was different. They were different because now they were dating. Being kids sharing a sleeping space is a completely different situation than sharing with your significant other which, wow, each time Izuku thinks on it he still can’t believe it’s real, their relationship.
That night had been movie night for class 1-A, a tradition that had been put into place not long after moving into the dorms. Their classmates had been all for it when Momo had suggested it as a bonding experience since they were likely going to work together for the next few years and needed to be comfortable together. Well, all but Bakugou who just snorted and said it was lame, but somehow always ended up sitting on the couch or floor watching along with everyone else. Since starting their relationship a few months before he had taken to grabbing Izuku and basically manhandling him to sit in his lap everytime and ‘cuddle’ though Katsuki would likely blow his head off if Izuku ever said that to his face. Izuku had learned that Katsuki was a very...physical person since their first date. He always had an arm around Izuku’s shoulders or his waist and liked to pull him in so that their bodies were parallel, hip to hip. And while not necessarily possessive in the common sense, he didn’t take too lightly to others flirting with Izuku, which was happening more often as his hero career grew traction.
After the movie ended (tonight was Moana which made Izuku cry at least three times prompting Katsuki to call him a wimp) Katsuki had stood and stretched, leaving Izuku to fall flat on the couch where he had been leaned up on his chest (which, rude Kacchan) Katsuki brushed off Izuku’s minor whining and announced that they were going to bed before grabbing Izuku by the wrist and practically dragging him behind him towards the rooms. “K-Kacchan! My room is back that way!” Izuku stuttered, but didn’t try getting away. Katsuki glanced over his shoulder for a second before shrugging. “I know. You’re sleeping in my room tonight.” Izuku felt his face heat up instantly and started stuttering nervously while Katsuki just rolled his eyes. “Shut up nerd, it’s just sleeping. Don’t make a big deal out of it, I just didn’t feel like sleeping alone tonight.” Katsuki’s voice was its usual harsh tone, but Izuku could see his ears turning pink and his heart fluttered.
Upon entering the room, Izuku took the small time window he had to glance around the room, finding himself a bit surprised. Katsuki’s room was surprisingly organized for someone with such a hectic personality. His clothes were all neatly stacked away into his closet and dresser with a hamper for dirty clothes. He had a white, simple desk where school books and what looked like reference materials sat neatly divided.There were a few personal touches here and there, Izuku spotting one picture of the Bakugou family on the desk. And right there on the nightstand next to the bed was a snapshot of he and Katsuki when they were younger. It was a cute shot with both boys in identical All Might onesie pajamas. Izuku didn’t think Katsuki would have kept that one, but seeing it shot a bolt of happiness through Izuku.
A shirt hitting his face broke Izuku’s gaze with an indignant squak, arms flailing to grasp the cloth. “You can sleep in that tonight, but don’t expect it every time Deku.” Katsuki’s muttered and Izuku looked down to examine the shirt. He saw the face of his mentor All Might smiling up at him, a backdrop of fireworks and the words “Plus Ultra!” plastered on the top and bottom in stark red and blue lettering. It was...interesting. Definitely something that would be manufactured for All Might memorabilia. Izuku glanced up at Katsuki and squeaked in alarm at seeing the other boy shirtless, flipping around quickly. “Shit Deku, you act like you’ve never seen a shirtless guy before.” Katsuki grumbled and Izuku felt really stupid. He was overreacting he knew, but he couldn't help it. Katsuki wasn’t just a shirtless boy, he was his shirtless boyfriend. The boyfriend he was about to lay down with and sleep through the night.
Gathering his nerve Izuku threw his shirt off and hastily pulled the other on then, with a moment of hesitation, removed his pants so that he was only in the shirt and his All Might boxers. The shirt was pretty big on him, coming down to his knees and Izuku wondered where Katsuki had gotten it from. When his back was turned he discreetly breathed in the scent on the shirt. It smelt of smoke and a hint of Katsuki’s cologne and Izuku felt a bit giddy because he loved Katsuki’s cologne. Hearing a rustling noise, Izuku turned to see Katsuki turning down the bed and crawling in before looking at Izuku expectantly. “Gonna stand there all night or are you gonna get in?” He sneered and Izuku approached the bed, standing uncertainly about how they were going to do this. Katsuki rolled his eyes, pulling back a section of the blankets and glared at Izuku pointedly until the other climbed in. The two laid there for a few minutes both stiff and awkward with neither really knowing what to do. Katsuki shifted a bit so that he was a little closer to Izuku and lifted his arm up. Izuku looked confused until Katsuki grunted in exasperation and finally wrapped his arm around Izuku and dragged him partially onto his chest. Izuku finally got the picture, wriggling until he got a comfortable spot with his head on Katsuki’s chest.
And oh wow this was nice and geez Kacchan was so warm and his heartbeat was right under Izuku’s ear and did Kacchan normally have his body temperature this high? Could this be a side effect of his quirk maybe? He should ask him, that would be useful for his notebooks. And while he was at it he should ask about the smoke smell that clung to his clothes. Were they always like that? Could it be washed out? Did it only happen when he used his quirk or did it-!
A light tap of a fist on Izuku’s head startled him. “Stop your creepy ass mumbling and go to bed.” Katsuki mumbled and Izuku flushed again as Katsuki’s hand settled in his hair, the other reaching over to grasp his hand lying on Katsuki’s sternum. It was nice. Izuku was already feeling drowsy, his contentedness at being so close to Katsuki, breathing in his smoky scent was lulling him down to darkness. Usually Izuku had a hard time sleeping, his mind always running a million miles a minute, but right now he felt like he could sleep for a year no problem. When Katsuki started petting, (petting!) his hair Izuku was gone. He had never fallen asleep so fast in his life.

Izuku woke up, groggy and a bit disoriented, unable to pinpoint his surroundings. He could tell it wasn’t morning yet, but had no clue what time it was. All he knew was that he was still very sleepy, he was so warm and that someone was holding him, holy crow SOMEONE WAS HOLDING HIM! Izuku’s first instinct was to try to dislodge himself, but when he inhaled he caught the distinct smoky, gunpowder type of scent that only belonged to one person he knew. After a minute of confusion he remembered that he was in Katsuki’s arms. Being held by Katsuki. Very tightly he might add, though not uncomfortably. At some point the two had rolled over so that Katsuki was spooned up behind Izuku, practically glued chest to back. One arm was wrapped across Izuku’s stomach, towards his diaphragm and the other was wrapped around his neck. He was being held firm, but not in a choking sense. Actually it was rather...nice. There was also one leg thrown over his hip and the other wrapped around the bottom part of his legs, effectively pinning him to the bed. But he liked the way Katsuki’s arms encased him, his whole body covering him as if to shield him in a way.
Izuku hummed low in his throat and swore he heard a reciprocal hum from the still sleeping Katsuki. Placing one hand gently on the arm covering his stomach Izuku closed his eyes and fell back to sleep, Katsuki pulling him just a little bit tighter to his body in response to the other going lax. That night, both boys slept better than they had for years.
