Chapter Text
Sleeping with Eijiro was a bit of a hassle.
He never could keep to himself. Always needed to lay directly on Katsuki. This presented itself as a big problem when they first started to have routine sleepovers in their second year. It messed with Katsuki's sleep schedule. So, he made it clear that it shouldn't happen again. Which it didn't because Eijiro started avoiding him.
"Oi fuck is your problem?"
"H-huh"
"Immediately after tutoring you fucking run away. D'you think I'm going to fucking eat you, asshole?"
"N-no Kats it's just... I never want to make you uncomfortable, and I can't really seem to keep to myself while I sleep"
"Well don't go fucking deciding how i feel for me. I never said I was uncomfortable"
"Y-yeah but you-"
"I said it messes with my sleep, shithead. Tell you what if you can sleep without completely suffocating me with that 400-pound body of yours, we can make this work."
---------------
Later that night before it was time to sleep Eijirou put himself at a respectable distance from Katsuki. It wouldn't be manly to go against his bros wishes.
"Oi why the fuck are you so far away?"
"Uhm I-"
"Get over here Eiji."
God if that didn't make him just want to smother him in his scent. He couldn't quite understand it this odd possessive feeling he felt around him. Like he needed to keep him safe. To protect him. Have him. Which isn't right Bakugou isn't property he's a human being in and of his own right which makes it odd when this weird feeling surfaces whenever he's around him. He feels like he needs Katsuki, needs to be close to him, and protect him. The puzzling thing about it though is realistically there really isn't anything to protect him from. He can't tell Bakugou all this though, so he opts to just scoot himself a little closer and struggle with the uncomfortable itch that settles in his skin from not being able to lay directly on top of him.
"I didn't say fucking scoot a little. What's wrong with you today."
It's said in a harsh tone of voice, but Kirishima understands what he means.
"Nothing." He says softly but Bakugou clearly isn't convinced.
"Don't fucking lie to me Ei. What the fucks your problem tonight. I already told you I'm not uncomfortable."
"Y-yeah it's just... I really can't umm sleep comfortably without being really close to you. Um I just kinda feel like I should protect you. And before you say anything no, I am not looking down on you I just I don't know man. It feels like I need to be in your skin sometimes or else I feel so uncomfortable in my own skin you know."
No, Katsuki didn't know but what he did know was that this little tirade Kirishima had just gone on certainly wasn't helping with his feelings.
"Just fuckin get over here Ei. Don't fight yourself if that's how you really feel."
Eijirou stared at the blush on Katsuki's face looking everywhere but at him. He hadn't really expected him to understand.
He jumped rather excitedly on Katsuki to give him a hug. "Aw katsuuu thanks for understanding."
Katsuki groaned " I was serious though don't put all your weight directly on me it messes with my sleep."
"Okay!"
Yeah, they could make this work
-----‐-----‐‐
Through the progression of their first year Katsuki found he didn't really mind the subtle touches Eijiro gave him. He had hated it at first, someone he had only known for a few months in his personal space, but as time progressed he found he really didn't mind it. It seemed Eijirou himself was rather oblivious to it himself anyway.
After the kamino incident the touches had gotten bolder.
The once nervous brushes against his shoulder slowly turned to intentional touches. Slowly but surely, Kirishima made himself a constant presence permanently perched atop Bakugou's shoulders. While having lunch with their friends his legs would brush against Bakugou's and he would keep it there. If Bakugou moved his leg he would just move his, so they were touching all over again. If the others noticed they didn't say anything at least not to his face. And despite the odd new pattern Katsuki let him. Because the glint of sad possession in Kirishimas eyes whenever he would move away made him feel like a piece of absolute shit.
So, he let him. Even when he would cook and Kirishima would loosely wrap his arms around his waist. The first time it happened everyone around them had gasped and whispered but it seemed over time everyone just adjusted.

"Have you ever thought about how Katsuki smells so sweet?"
"What?" Mina seemed a bit confused, so he chose to clarify
"Y'know he always smells so sweet like caramel."
Mina let out a short chuckle. "He smells like old spice cologne Eijiro I'm not sure what you're talking about."
"No like without the other scent. The one he has after a fight."
"Yeah..no, babe. I don't really think I do?"
" Kirishima, I think it might just be your undying love messing with your brain but kacchan smells about as normal as everyone else."
They didn't understand. Why did they not understand? The oh so intoxicating scent that clouded his senses and made his mind go numb whenever it was in his vicinity. The one he could never quite get enough of. And now they're telling him that Katsuki doesn't have one.
That simply wasn't possible. His mind could NOT have made a scent so intoxicating up. Hell, he even has the clothes he 'burrowed' from Katsuki's gym bag to prove it. He had spent nights basking in the scent of it and mornings cleaning up the mess it had made in his pants when he went to sleep with it too close to his face.
That's odd maybe they just don't have good noses.
......
Over the next few days Eijirou becomes aggressive. Which is unlike him. He knows this, Katsuki knows this everyone knows this. But the thought of HIS Katsuki so close to anyone that isn't him makes his skin crawl. It fills him with an unreasonable amount of rage when he sees Katsuki talking with Izuku. When Hanta lightly pats Katsuki's back in a friendly way. He hates it. The sick feeling that crawls under his skin. The unbridled hate he feels for people he knows he loves.
His final straw comes when some 1c girl has the audacity to ask Katsuki out. It is not exactly a disrespectful interaction. Nothing out of the ordinary really. She just asks Katsuki for his number and if he's free on Saturday. It's nothing out of the ordinary but it makes Eijirou see red.
"Don't you ever fucking talk to him again. He's mine."
The poor girl visibly shaken up moves away with the speed of a child who just got caught stealing.
Now snapped out of his rage filled state he is suddenly filled with a sense of fear. Why the hell would he say that? They weren't even dating for goodness' sake. When he turns to Katsuki his face is filled with rage, this is to be expected, but more than anything he sees the look of outright confusion on Katsuki's face as he stares pointedly at him.
"What the fuck is up with you?"
"I-I don't know Kats... Sometimes I just it's just... I don't know why I did that sorry"
Katsuki studies his expression with growing confusion.
"Whatever not like I wanted some extra talking to me anyways."
Eijirou takes such delight in this statement he doesn't know what to do with himself.
"Aww Kats be nice they're not extras."
"Whatever s'not like you were either."
They make their way out of the lunch hall together Katsuki couldn't help but notice the possessive hand that wrapped around his waist.
--------------
"Is it hot in here? I'm really hot."
"Eijirou we have the air-conditioning on what more do you want us to do wait... are you ill?"
It's not an unreasonable question to ask after all. His face is flushed and he is panting like he has just run a marathon which he obviously has not as he is situated in the middle of Bakugou's room for their evening study sessions.
"I-I I don't uhm know..." He lets out a groan that sounds almost inhumane when Katsuki gets close to him to check his temperature.
"F-fuuu.... Kats you smell like. Like..."
"Like what Eiji? "
