Chapter Text
The door creaked open and Izuku heard quiet steps coming inside. Without having to ask, he immediately knew who it was. The door clicked shut as Katsuki made his way to the bed, Izuku already deep in the covers and facing away from the door. The blonde wordlessly lifted the blanket and crawled in next to Izuku, arms easily enveloping him from behind.
“Hi,” Katsuki whispered, as he rested his forehead between his boyfriend's shoulder blades. Izuku reached for Katuki’s hand, pulling it under his shirt then pressing it flat onto his chest.
“Hi,” he whispered back, a smile apparent in his tone. Squeezing the blonde's hand gently, Katsuki slotted his leg between Izuku's. The day’s training was intense and the pressure from upcoming exams was piling; he just wanted to be close to his boyfriend. Katsuki would never admit it, but this was his favorite part of each day. Waiting until the lights were off and the world was quiet, to sneak into Izuku's dorm. Sometimes he was already asleep when he got there, but it was just as rewarding being able to be near him. To breathe the air that was so intoxicatingly Izuku. To hold his hands, scarred with marks that showed just how dedicated he was in becoming a hero.
“Are you tired?” Katsuki nudged his back with his nose. Izuku hummed in consideration before flipping around, now facing his boyfriend. He noticed the playful look in his scarlet eyes and knew where this was going.
“No,” Izuku replied, scooting closer to Katsuki; chests pressed together and legs tangling under the sheets. He tilted his head up and briefly brushed their noses together, eye contact intensifying as they both breathed each other's air. “Are you?” he asked, flicking his tongue out as he absent-mindedly wetted his lips.
Katsuki's eyes glanced down and gazed at the action, his own lips parting slightly as he sucked in a breath, “no.”
Izuku brought his hand up and started tracing Katuki’s bottom lip with his thumb, his other fingers curled horizontally under his chin. He pulled on his lip and Katsuki immediately opened his mouth further, eyes half-lidded. Izuku smirked and looked back back up, just to see that the blonde's eyes were already staring into his emerald ones.
Katsuki started to lean in, but Izuku had other ideas. He pulled away right before their lips met, his tongue just slightly poking out and his smirk grew wider. Katsuki paused at the feeling of air instead of lips and blinked at Izuku, an incredulous look forming on his face.
“Did you just–? Get back here Shitty Nerd!” Katsuki reprimanded with no actual venom in his whispers, reaching to pull Izuku closer. Izuku giggled and bit his lip before swiftly placing a peck on Katsuki's lips. He pulled away, but before he could get too far Katsuki grabbed the back of his neck and crashed their lips together again, this time making it deeper than just a simple peck. Izuku's lips were warm and inviting, and even though he was previously teasing, he let Katsuki kiss him with no signs of wanting to stop. Katuski pressed his tongue against Izuku's bottom lip, and he easily parted, letting Katsuki enter.
Soft sighs and breathy moans filled the room as the kissing got more and more intense. They parted for air after what felt like hours, and Katsuki smoothly adjusted so that he was slotted over his boyfriend and in between his legs, arms caging him in. Izuku took the opportunity to wrap his legs around Katsuki's hips, pulling him closer. He reached up to drag the blonde down, as they'd been separated for too long.
Katsuki kissed Izuku deeper than before, parting every few seconds before diving right back in. Izuku wrapped his arms around Katsuki's neck, tugging at his hair but not pulling him off. One of Katsuki's hands found its way under Izuku’s shirt, and was steadily holding his waist. The other hand was cradling his cheek, much more gently than the way he was kissing him.
Katsuki pulled away but let his lips linger near, then began trailing open mouthed kisses down Izuku's face and onto his neck. They had never gone this far before, and Katsuki wanted to make sure Izuku was alright.
“Zuku,” he breathed against his neck, “is this okay?”
“Y-yes. Yes.”
“You have concealer, right?”
“Yeah,” Izuku breathlessly nodded as he dragged his hands through Katsuki's hair, silently urging him back down to his neck. The blonde began kissing his neck again, this time stopping at some places. He looked for when Izuku would tug on his hair a bit harder, or squeeze his legs around him tighter.
Katsuki stopped at the crook where his neck and shoulders met, then started kissing it with a fervent love. Izuku gasped at the feeling, then turned his head the opposite direction, to give his boyfriend a better angle. Katsuki gently bit down, and Izuku let out a soft moan as his shoulder tensed slightly. He was quickly relaxed though, as the blonde began sucking and soothing the bite with his tongue.
“Ah! Kacchan…”

Kirishima was in the dorm building’s kitchen, grabbing a glass of water, when he heard a strange noise coming from… Midoriya’s room? It was a cry of some sort, and although it was muffled, he definitely heard something.
Is Midobro okay?? I better check on him. Good thing I was thirsty at this time, who knows what type of trouble he might be in!
Kirishima set his glass down on the counter, quickly forgotten as he crossed the hall and stopped in front of the sweetheart of class 2-a’s dorm room. He stood there for a moment longer, ear pressed against the door to listen for any clues as to what could have happened.
It was quiet for a moment, but soon after the silence he could hear another cry. Kirishima forgot to knock, hearing that his friend may be hurt, and reached for the door. He was easily able to swing it open, since none of the dorm rooms were able to lock in case of a sudden villain attack.
He rushed into the room, expecting the worst.
He most certainly was not expecting this.
