See the end of the work for more notes Honestly, Katsuki was never meant to find out. If he was being honest with himself, and if Izuku was being honest with him. It was all a big shitty mistake.   It happened when Katsuki was walking down the hall, going to visit his boyfriend. He made an effort to be...romantic? That wasn’t the word for it. He tried to put in some form of effort to at least have some idea of what this relationship was supposed to be. He wasn’t gonna fucking buy flowers or take Izuku on a date to a place that’s more expensive than what his shoes cost. That was Izuku’s job. He was disgustingly sappy. That shit just wasn’t Katsuki’s style. He made sure he saw or at least talked to him once a day, outside of school hours, because he’d be damned before he’d show affection in front of those fuckfaces.   It was an average friday night. Earlier, the rest of the class was watching a movie in the common room, but Izuku was surprisingly nowhere to be found. He was normally in the center of these things, so it was at least the cause of a little worry. He was stretched across the couch, watching whatever dumb romance Shitty-Hair and the girls wanted played.   Round-face looked up after a few minutes and seemed to look across the room, eyebrows furrowing. “Where’s Deku-kun?” She asked, popping another fistful of over-buttered popcorn into her mouth. Frog-Girl looked around from next to her.   “It doesn’t look like he’s here, ribbit.” She shrugged before reaching into her own popcorn with her tongue and snatching some up.   “Yeah, where is he?” Shitty-Hair asked, sitting up from where he was cuddled up with Scotch and Pikachu. “He was the one who wanted to hang out in the first place!”   “It’s very unlike him to miss these things…” Glasses agreed, cupping his chin with a hand. It was practically fucking visible how hard he was thinking.   “I don’t fucking know. Deku does dumb shit sometimes. “ Katsuki growled out. “Why should we care where he is?’   “He’s our friend, Bakugou.” Glasses glared at him. “Not that you’d know. You don’t seem to even try and get along with him.”   Katsuki’s vision went red. “Stay out of my business, fucking nerd!” He snapped. He was DATING Izuku, for God’s sake! They didn’t know that, but it was still infuriating to be treated like he was still...who he used to be.   Shitty-Hair smirked. “Lay off, Iida. He’s gay for him.” With that, Katsuki’s face went red too. Kirishima didn’t even know they were dating, were they that obvious?!   “Oh? My apologies, Baku-” “Fuck this! I’m gonna go take a piss.” Katsuki sneered and stood up, then stomped out of the area. Where was he, anyway? He was the one who started organizing this. For bonding or some shit. Why wasn’t he there?   He stomped up to Izuku’s floor, planning to break his door down to see why the nerd wasn’t where he needed to be. He didn’t do that, since the thought that Izuku was asleep popped into his head. He would freak out if he was woken up suddenly, especially if it was a nightmare. The boy was prone to those, sadly. Bakugou turned the knob slowly and pushed it open, looking inside.   What he saw wasn’t what he expected at all, actually.   Izuku was standing in front of a mirror, staring at his reflection with a small, innocent smile on his lips. That wasn’t what was surprising.   The boy swiveled his hips slowly, smiling wider and happier as the skirt lifted and moved with his body, ruffling and waving in the air around his thighs. The skirt. THE SKIRT!   Katsuki’s jaw dropped and his mouth hung open dumbly as he stared at the boy. The skirt appeared to be cotton. It was a plain black, pulled up to his waist with an All Might t-shirt tucked into it. Izuku looked so fucking happy with it! To say that Katsuki wasn’t confused would be a lie, but to say that he didn’t like it would be an even bigger lie. He was fucking cute.   Suddenly, the smiling nerd looked up, beyond the skirt in the mirror and his eyes widened with panic. He gasped and whipped around, staring at him. The whole scene flashed DANGER with big red letters.   “K-Kacchan! G-Get out!” He stuttered, pale yet blushing so much.   “Deku…” Katsuki started. “What the fuck is this?”   Silence.   Oh shit. Oh SHIT. That's not how that was supposed to come out.   Izuku bit his lip and looked down, face screwing up as his eyes slowly filled with tears.   Katsuki’s mind screamed and cursed when one trailed down his cheeks and hit the floor.   “I-I’m sorry Kacchan…”     Katsuki almost growled at how sad his voice was. He Did That. Fuck. Maybe Glasses was right-   1. FUCK NO. He’d prove them all wrong. He’d be the best boyfriend ever. The one Izuku deserved.   “Wait!”Katsuki exclaimed, pushing the door shut. He hurried across the room, practically running when he pulled Izuku into his embrace. “You can’t rid of me that easily, nerd.” He scoffed into fluffy green hair.   Izuku choked on a hiccup. “B-but, you don’t like it.”   “Just ‘cause I’m confused doesn’t mean that I fucking dislike what’s happening. Talk to me.“   “I-I…wanted to feel pretty,” He whispered.”I wanted to feel...beautiful. So I asked my mom to get a skirt for me...and I could tell she was confused, but she’s always so supportive, so she ordered me one! And I feel really, really nice in it, and it looks good..but I’m worried how people will..react.”   Katsuki huffed. “You look fucking cute.”   He knew how supportive Inko was first hand, when as a child Izuku became aware of himself. Luckily, it was before puberty even hit, so it was easy to get treatments and pass when he never developed anything to go against his gender. He was as manly as everyone else, obviously. However, he could easily fucking see why Izuku was worried.   “It’s not like...it’s not like I’m a girl, or anything.” Izuku hurried out. “I’m a boy. “   “I know. Not questioning your masculinity or whatever,” Katsuki grunted.   “People will think I’m having second thoughts. People will think that I’m not a boy anymore, and I was so worried you would think so too, Kacchan!” Izuku blurted.   He snickered. “Have a little more faith in me, nerd. Fuck. You thought I’d be an asshole about this shit?”   Izuku smiled and Katsuki could feel it against his chest. “A little bit.”   “Clothing is for everyone, I don’t fucking care what it is. I don’t have a problem with you wearing anything. In fact….” He smirked and pinched Izuku’s ass. “It’s cute.”   Izuku squeaked and laughed, hitting him in the shoulder. “Stooooop. It’s embarrassing.” “I wouldn’t have any problem with you dressing like this more often, is what I’m saying.” Katsuki laughed.   “Okay, Kacchan.” Izuku giggled, covering his mouth with a hand.   “Now, are we gonna go watch this fucking movie or what?” He raised a brow, challenging him.   Izuku looked up at him. “I’m gonna change,” he said shyly. Katsuki’s heart broke a little. But he nodded. “It’s a little personal. I’m not ready to show them. Not sure if I’ll ever be,” the green haired boy said with a bashful smile.   Ten minutes later, they went back to the common room, everyone cheering and greeting Izuku loudly.   The highlight of his night had gotta be when he sat down on the couch he always sat on. Izuku, who normally sat with Round-Face, sat next to him. He raised a brow at Katsuki, who couldn’t fight back. Izuku shoved his arm under his and leaned against him. Shitty-Hair whistled. Ugh. Everyone cheered for a second time.   Scratch the “highlight of his night” part. Katsuki wanted to fucking die.   ===============================================================================     The second time wasn’t so accidental. It was definitely planned, on Izuku’s part.   It all started on another Friday night, when most of their class was downstairs, watching some horror movie and probably shitting themselves in the process of doing so.   He was about to head down to the common area like always would on Friday. He’d swear up and down that he hated doing it, but hanging out and feeling like he was part of a group that genuinely liked him and wanted him there, one that wasn’t scared of him...was overwhelming. In a good way. They picked fucking cheesy movies every time, though. That was the fucking issue. Bakugou could never get into them.   He’d never admit this either, but sometimes, he didn’t need to get into them. Having his friends around him and his boyfriend pressed to his side was enough. His routine was different now, revolving around going to get Izuku and walk him to the common room, even though it was a longer walk. He was trying to be a gentleman, damn it! The first time he’d done it, Izuku giggled and poked fun at him for taking a long trip. Katsuki exploded, denying it even though there was no way to do it. The green-haired boy stood on his toes and kissed his cheek, smiling brightly. “ Thank you, Kacchan.”   Katsuki knocked on the door, loudly. “Deku! Open the fucking door before I knock it down!” He called inside. The threat was empty, as it always was. Just an extra motivator for Izuku to actually open the door.   “Come in, Kacchan! The door’s open!” His boyfriend’s voice called from inside. “I’ll be ready soon!”   Katsuki pushed the door open, gently, especially compared to his empty threat. What he saw stole the breath from his lungs and choked him at the same time. Fucking unfair.   His boyfriend was sitting at his desk, bent over a homework sheet. Normal, except for how he was dressed. He was clad in a white, pleated skirt that only met his upper thigh when he was sitting down. On top of that was an oversized, baby-pink sweater that gave him serious sweater paws as he scribbled on his homework. His feet were covered in white socks that came up to his knees. Katsuki struggled to breathe as Izuku looked up.     “Close the door, Kacchan,” He said softly, in a higher and lighter pitch than his normal tone. Katsuki knew what that meant. Of course he did. Fuck. He’s fucked.   He pushed the door closed and stood, frozen. Izuku smiled softly and rolled his eyes before he stood and walked over to him, skirt swishing just the slightest with his movements. He wrapped his arms around the blond’s shoulders and pressed up against him, chest to chest. He stood on his toes to kiss him, lips soft and covered with a gloss he didn’t see before feeling the sensation of them against his own. Fuck. Fuck fuck fuck.   Izuku giggled against his lips and Katsuki darted his tongue out to taste whatever lipgloss he was wearing. It was sweet, like a fruit he’d never tried. The green haired boy parted his lips for him and he didn’t waste his chance in sliding his tongue in. Their teeth crashed together with the explosive teen’s desperation for his boyfriend, even though they should have had enough practice to where that didn’t happen anymore. Izuku squeaked and opened his mouth wider, tilting his head. Katsuki cupped his cheeks and forced it farther, eliciting a whimper from the boy. Hei claimed his mouth with his tongue, completely dominating the kiss.   Izuku hopped up and wrapped his legs around Katsuki’s waist. The blond caught him and held him up by this thighs, carrying him to the bed and dumping him over the comforter without breaking the kiss. Well, until he dropped him.   Izuku bounced once and giggled, lips free of gloss and swollen. He parted his legs and smiled sweetly at the blond. “Like it, then?’ He asked teasingly.   “Do I like it?” Katsuki asked roughly, pondering over what was best to do to demonstrate how he felt about it. “You tell me.” he breathed out and gripped Izuku’s wrist, pulling it to press against his clothed dick that was slowly reaching hardness in his pants. “Do I fucking like it?”   Izuku’s breath hitched and he nodded with a smile, a little wildly. “Kacchan really likes it.”   “Now-” He thought. He rubbed the inside of a spread thigh, watching Izuku shiver. Always so sensitive. “What does my little slut want me to do to him in his pretty clothes?’   Izuku whined and closed his eyes tightly. “Kacchan-” He protested. He hated dirty talking. Hated being embarrassed, hated the way his cheeks lit up and how he stuttered.   “Tell me, Deku. Or else.” Katsuki gripped his hair and pulled his head back, forcing him to arch his neck and strain to look at him. “What do you want me to do to you?”   “Ah-Kacchan-I w-want you to-” he took a deep breath. “Fuck me, Kacchan! Touch me. I wanna be yours.”   The blond  smirked at the words. “You’re already mine, Deku.” he gloated. “You’re always mine, no matter what.” Izuku made a loud whining noise, before replying.   “Yours, Kacchan!” He said in what was almost a chirp, lips spreading into a dopey smile.   “Fuck, you like that? Being mine?” A violent nod from Izuku answers him enough. “I’ll make sure to fucking remind you a lot more often, then. “ He hummed happily at it.   “How are you gonna do that, Kacchan?” he asked, eyes full of lust and happiness.Katsuki slid his hands up Izuku’s thighs and pulled him closer to him, to where his legs had to part further to accept him.   “I’m gonna have to mark you up.” Kacchan gritted out, resisting rolling his hips to grind against his boyfriend. “Show the world you’re mine.” He grunted and Izuku moaned softly.   “Want everyone to know I’m yours.” He whined.   Katsuki smirked. “Me too. “ he went to push up Izuku’s skirt, sliding his hands up his thighs until he laid it on his stomach, when he found the best part of the whole outfit.   His jaw dropped for the second time that night. He took a sharp intake of breath, almost choking him when he saw what had been waiting for him.   Izuku huffed out a laugh, smiling breathlessly. He panted for a second, looking for words to say. “Like them, Kacchan?” he asked in a breathy tone. He shifted, moving his hips and spreading his legs wider to expose himself.   Izuku was...wearing fucking panties. Not anything particularly exciting or racey, just... little blue ones. They went up to his hips and had a lace waistband. If a girl had been wearing them, they would have been awfully plain. But with Izuku….it was a lot different. First of all, he’d probably look good in anything, so Katsuki wasn’t gonna pick and choose. Second of all, it was so unlike him. He’d only ever seen him wearing boxers until today. Sure, some of those were more attractive than others, just because of how color and style worked, but nothing compared to this. They were pretty and dainty, just how he wanted to look. It looked a bit strange coupled with his strong thighs and abs, but it was still fucking hot. Katsuki wanted to taste them.   “Kacchan~” Izuku whined. “Say something.” He squirmed as he grabbed his thighs, holding him still.   “They’re so fucking hot, Deku.” Katsuki said, looking back up to his face. He was blushing brightly and his eyes weren’t completely open.   “Kacchan, hurry. Fuck me.” the boy whined and kept squirming. Katsuki got up and sat down next to him before violently pulling him to sit on his lap. He laced his fingers through fluffy green locks and yanked him down to smash their lips together. Izuku groaned into the kiss and gripped his shoulders. The blond couldn’t find room to complain about him getting handsy, so he did the same thing. He moved one hand away and out of his hair, but kept the other there to make sure he completely dominated the kiss. His hand came to rest on Izuku’s thigh, which caused him to let out a whine. “Kacchan!”   Katsuki pulled away from the kiss and took hold of Izuku’s hands, leading them to his thighs as well.”Lift up your skirt,” He commanded. The boy hurried to follow his command, fumbling fingers struggling to pick up the fabric and hold it up as quickly as humanly possible.   Katsuki rubbed his fingers over soft cotton and Izuku lets out a whine. “Kacchan~” He’s never gonna be able to take the nickname seriously anymore, but he says that every time. It somehow always regains its childlike innocence after being moaned out. The blond boy raised a brow as a wet patch was quickly formed.   “You’re fucking soaked. What the fuck.” He muttered under his breath.   Izuku let out a sigh of a laugh. “I know it’s against the rules, but I know you get impatient...so I prepped myself.” He admitted, looking down and blushing with more than exertion.   “You’re gonna fucking get it, Deku. Maybe not being able to walk tomorrow will be enough punishment.” Katsuki responded, smirking at the teen on his lap.   “I know…” Izuku pouted at him. “I think you’ll appreciate it, though.” He winked. The explosive teen couldn’t hold in a chuckle. He definitely agreed. He needed to be in his tight, wet heat as soon as possible. He took a deep breath and Izuku whimpered and squirmed. He knew what that meant.   He exhaled slowly, trying to compose himself just enough to take everything a little bit slower. He wasn’t patient enough to really draw things out, just enough to tease. If Izuku wanted to have a long session, Katsuki had to come several times, even if Izuku didn’t get to. The green-haired teen squirmed more before he stopped him by gripping his hips hard enough to leave a bruise. He whined when he was still and avoided looking at the blond, embarrassed at his behavior. The blond had to hold back another chuckle at how quick he could go from zero to one hundred and back again.   “Sit up a little bit.” He muttered. Izuku complied, as he always did, and straddled him more than sat on his lap. Katsuki pulled the panties down and they both wiggled around awkwardly until he could completely remove them. The lapse in easy flow was quickly forgotten as lips collided once more, opening to allow teeth to clack and tongues to tangle and curl. Izuku breathed out soft pants, tiny squeaks of noise alongside breath. Katsuki left nothing in his mouth clear of his own saliva, he wouldn’t leave a square millimeter of space where his tongue hadn’t slid over. He considered the fact that he was still dressed, then groaned at the thought of having to pull away. Izuku seemed to take this as a compliment, as something to tell him to keep going. He tilted his head more and started to kiss him with more furiosity, lips moving quickly and tongue without forgiveness as he did what Katsuki had done previously.   He scooted closer to him on his lap, pressing their fronts together and grinding against the front of Katsuki’s slacks, whimpering at the jolting coldness of the button and zipper against too hot skin. He finally pulled away with a growl, though he was thirsty for more. “Give me a fucking second, Deku. I gotta get undressed.” Izuku whimpered pathetically as he was shoved from his lap. He stood to yank off his shirt in a fluid movement. He unbuttoned his pants, watching the way a pink tongue darted out to taste bruised flesh. Katsuki smirked and winked before, at a tortuous pace, unzipping the fly and pushing his pants down his thighs and off.   Izuku whimpered again, watching the blond slowly trace the waistband of his bowers.His erection was clear through them, twitching and at full length. He hooked his thumbs underneath the elastic and pulled, snapping them teasingly against tanned skin. Katsuki just used that as encouragement and palmed himself through the snug fabric. The teen on the bed had to resist reaching down to do the same, hand visibly twitching against the fabric of the skirt. The other chuckled before doing the same to his boxers as he had to his pants and stepping out of them, showing off his full and naked glory. Izuku looked him up and down, wetting his lips again and swallowing thickly.   Katsuki stepped away to rummage through the desk drawer for a condom. Izuku made a low whistling noise when he turned and Katsuki rolled his eyes. He grabbed the package and turned back to take his seat back on the bed before dragging him back on his lap. He made a happy whining sound and ground down against him once again, causing the blond to bite his lip and close his eyes. Izuku gently took the package and opened it with his teeth, before taking the condom and rolling it slowly onto his boyfriend. Izuku was on birth control, of course, they were seventeen and wanted to be heroes, but they weren’t going to take any risks. Risks like children were for when they were adults and had a smaller chance of dying. Katsuki groaned deeply and waited for him to be done. The green-haired boy smiled at him before sitting up his thighs, only to be stopped by the other.   “Not yet.” He said, with difficulty. Izuku groaned and laid his head on Katsuki’s shoulder, going back to holding his skirt with trembling fingers.   “How long until?” He complained, loosely mouthing at where his boyfriend’s shoulder met neck. He chuckled dryly.   “Dunno. However long I want, slut.” Izuku jolted at the language and whimpered.   “Yes, sir. Whatever you want.”  He screwed his eyes shut as the blond cupped him firmly, not touching anything but making the green-haired boy want to grind down until he could cum. He wouldn’t, though. He knew he’d be punished.   Katsuki smirked at how much he controlled himself. “Good. “ He grunted and trailed his hand up, brushing his swollen clit and making Izuku gasp and sigh. The blond slipped two fingers into his slit and ground against the bundle of nerves, making his hips stutter and a groan slip from his mouth. He took away the pressure and rubbed light circles against him, continuing with flicking and rubbing until he could see his thighs tense and his stomach muscles jump, until his moans started to get higher and higher and he could practically feel his cunt throb-then pulled away.   Izuku let out a strangled moan, hips chasing sensation as he was left on the edge. “Kacchan!” He yelped, voice thick with desperation. Edging himself before was a mistake. It didn’t even speed up how fast Katsuki wanted to go. He felt his eyes water as he hid his face against his shoulder again. “Wanna cum.” He whimpered.   The boy laughed and ran his dry hand through soft hair before yanking back, forcing the other to look him in the eyes. “You almost did without my fucking permission. Luckily, I’m not an idiot and can tell. “ He started to rub light circles against and Izuku whimpered again, eyes closing. Katsuki pulled away quicker this time and shoved him onto his back on the bed.   Fuck, he needed his mouth to be on him. “Hold your thighs.” He said and pushed them apart, lifting them slightly. Izuku scrambled to hold them, hooking his wrists under them and splaying his hand. Katsuki ducked down and reached up to pull white fabric over his head.   He buried his face in him, right where his legs met. He licked up and down his slit, painfully slow, lapping over his opening and dipping the tip of his tongue inside to retreat and flick at his clit. Izuku sobbed out a moan, desperate and shaking as he tried to hold still. Katsuki wrapped his lips around and sucked at the swollen and twitching bud until Izuku called out a broken “Kacchan!”   He smirked and tilted his head downwards, pressing his tongue inside and eating him out like he’d eat a dripping peach, slick sweet on his tongue and dripping down his chin. He pressed against his walls, making Izuku whimper and squirm. He did this until he tensed again, shaking and moaning nonstop. He pulled away once more, cock throbbing between his legs at the way Izuku keened and sobbed.   “K-K-Kacchan!” He cried out, nails digging into his thighs with the effort it took to refrain from touching himself and getting off. The blond snickered at how wrecked the other was before shimmying up and wrapping Izuku’s legs around his waist. He leaned over him and lowered himself until their chests touched, a soft sweater touching bare skin. Izuku whined as he started to mouth at his neck, sucking the spot below his jaw and slightly concealed. He tilted his head back but jolted and tensed when Katsuki started to push in. He pulled away from his neck and gritted his teeth, squeezing his eyes shut at the squeeze.   Izuku groaned, hips stuttering and canting up with every inch that Katsuki pushed in. He tried to hold him still, but it was a struggle, especially when he couldn’t control himself.   He took anywhere from a second to a minute to take deep breaths and get himself together. Izuku wouldn’t stop twitching against him, whining and pleading his name under his breath. Katsuki closed his eyes and took one more deep breath.   He pulled almost all the way out before pushing back in slowly. He moaned at the squeeze and the delicious friction. Izuku gripped the bedsheets and groaned, eyes closing at the pleasure. Katsuki slowly sped up until he was practically slamming into him, shaking the whole bed with his forceful thrusts. The room was filled with moans and the squeaks of the mattress.   Katsuki reached to pull Izuku’s legs further up and change the angle, slamming into him and smirking when the angle change worked. It was obvious from the louder moan that it tore from the green-haired boy’s lips. He could feel the sloppy wetness from the lube and Izuku’s own slick through the condom. It drove him crazy, forcing him to bite his lip and making his brain fill with a light haze.   The heat swelling in Katsuki’s abdomen boiled over as he hit his edge and toppled over it, his vision going white and his eyes squeezing shut. He rode it out, thrusting impossibly hard and moving his hand to rub at Izuku’s clit roughly as they both shuddered. Katsuki’s hips twitched as they slowed down, his muscles and bones melting into a satisfied mess. He mouthed tiredly at his boyfriend’s neck, keeping up the circles under a chorus of “kacchan, kacchan, kacchan-” that quickly got higher and louder and his hips twitched uncontrollably and his stomach tensed. He hit his own edge with a low moan, grinding down onto Katsuki’s thumb until his eyes shut and he relaxed into the bed, entirely boneless.   When Katsuki returns to reality, he’s laying on top of the green-haired boy. Izuku’s eyes are closed, but his lashes flutter against his cheeks like he’s not quite asleep. He pulls out with a groan at the slimy feeling and Izuku whines at the sudden emptiness. He opens his eyes, revealing sleepy green irises. They were unfocused, but that was expected. Katsuki tied the condom and threw it in the trash before grabbing the damp washcloth on the nightstand to start cleaning up. He pulled Izuku up slowly, by his arms. The boy let out another soft whine and stretches them out, flexing his wrists. Katsuki slips his hands into his sweater, running his hands up and down his sides. He lifts his arm ups sleepily, obediently. Katsuki feels his entire chest soften at the picture of his beautiful boy. He complies with Izuku’s silent question and pulls off the sweater, then runs his hands over his shoulders and kneads the flesh, sure to get rid of any knots. The green-haired boy hums and leans on him, a small smile spreading across his face.   This is the only time Katsuki can accept being soft and gentle, the soft afterglow of Izuku giving him his trust and body. He knows Izuku loves him and will never leave, but he knows the bargain of this. He must do what he’s doing right now. Aftercare is the only acception of his allergy to affection. Izuku needs it now, in his foggy and cloudy mind. There’s no room for judgement here. It’s safe.   “Mmm, Kacchan….” He whispered, wrapping his arms around his shoulders. He felt all of his stress melt away as he held the smaller boy in his arms. “Love you.”   Katsuki pressed a kiss to his forehead. He wasn’t quite ready for that. Izuku was his precious one, the thing he loved most in the world...but it was too much. He couldn’t force the lava up his throat and out of his mouth yet, not until he was sure it wouldn’t burn the two of them. Izuku knew this, and accepted it wholeheartedly.   Katsuki was so lucky.   He ran his palms up Izuku’s thighs, gently dragging the skirt down and off of him. He shivered at the chilly air on his naked body, reflexively curling up to find warmth. He trembled at the feel of the cold cloth dragged over his thighs and vulva, making sure he was properly cleaned. Katsuki gently hushed him and helped him into his own hoodie, a large yellow thing. He pulled it over his head and waited until he popped out with his sleepy smile. He helped his arms into it, wiggling and flailing until they appeared. He dragged a pair of red boxers, Izuku’s own, onto his legs and further until the waistband met his hip. He kept the knee-socks on, knowing he was easily cold.   Katsuki clothed himself less gently, wiping himself down and hurrying to put boxers and a shirt on.   “Kacchan~” Izuku whined,making grabby hands at him. Katsuki fake grumbled and lifted the blanket, crawling into bed next to him. The twin bed was much too small for them, but they didn’t complain. Katsuki pulled him closer, wrapping an arm around him. Izuku hummed happily and cuddled as close to him as possible. “Goodnight, Kacchan.” he mumbled.   The two fell asleep peacefully, not aware of their phones filling with texts from their classmates about them skipping movie night.
