Bakugou Katsuki was a man that all together didn’t seem interested in that many people. He cares enough about them he worries when they don’t check in during a mission or makes them soup when they’re sick. But whether or not they are dating anyone is just not something he cares about. 

Except for Deku. 

Deku had somehow wormed his way into his heart and his aggressive obsession had turned into something else, something better. But then that pure fluffy romantic feeling he had towards him made a sudden and severe change in a single day. 

He was eating lunch with the loser and he was talking and talking about who knows what when Katsuki got some honey on his hand. He licked it off his finger and the nerd stopped talking and simply stared. 

“Um, Kacchan?  Wha- what are you doing?”

“I got honey on my hand what’s it to ya?” 

He sighed as if relieved and awkwardly chuckled, his face bright red, “oh never mind Kacchan.”

Well, that was weird. 

But then a few days later it clicked in. 

He was on a mission with the nerd as they were third years and were basically heroes. He was sitting on the bed while Deku looked out the window. It was Katsuki’s turn to sleep but he wasn’t tired so he barked, “oi, Deku. Come up here.” 

“Wha?!” He gasped. “You want me to lay on the b-bed?”

“Yeah hurry up.” 

The obedient thing that he was blushed like a mad man and sat on the opposite side of the bed blushing like a virgin, that he probably was. 

“Go ahead and sleep, I’m going to take first watch.” 

Understanding lit upon his eyes and his mouth made an ‘o’ as he nodded and his face resumed the normal color. 

The fuck was that all about?

All at once, he understood. The nerd thought he was inviting him to the bed, and he was going to do it! No fucking questions asked. This opened a whole new door of thought. Could he fuck the nerd? Was that an option? 

He was pretty hot, but still a nerd. He had toned muscles and a good ass. He seemed to be a bottom which was ideal for Katsuki. Maybe this could work!

So he upped the ante and started purposefully flirting with him instead of whatever the fuck he was doing before. 

“Oi Deku,” he called out from across the training floor. 

“Yes Kacchan?”

“Why don’t come train with me later.” 

“Oh, I would love to!” 

“Yeah, we can do the training in my dorm.” 

“Um like studying?”

“Nope.” 

Izuku blushed all the way to his ears and walked away mumbling to himself. 

This was going to be fun. The rest of the class watched in awe as Katsuki blatantly and sexually flirted with him. 

He sent him notes with sexual innuedos like, 

This class is boring, want to take a bathroom break and make it less boring?

I’m kinda hungry, I think a fucking nerd will take the edge off, or maybe fucking a nerd. 

Deku was blushing and stuttering way more than usual. As entertaining as it was, he really started to get feelings for the nerd. It was getting more and more obvious that this was more than just a fling for him. He didn’t just want his body, he wanted his heart. But he did really want his body. 

One day his loser friends cornered him and said “are you messing with Deku or do you really like him?”

“None of your fucking business.” 

“It is our business if you’re just toying with my friend,” Halfnhalf said in a blank voice with stern eyes. 

“Oi! Don’t go making your own conclusions, I love the fucker, you got that?! He’s going to be mine.” 

Halfnhalf sighed and said, “he’s always been yours, take responsibility.” 

“I’m rooting for you Bakugou!” Uraraka cooed. 

Did he just say he loves him? God, he’s so in over his head. There’s only one thing to do. 

He walked into the classroom to see Deku just sitting at his desk. Katsuki shouted, “Oi Deku!” 

He jumped and looked over with big eyes. “Yes Kacchan?” 

Katsuki grabbed his chubby cheeks and pressed a long rough closed mouth kiss on his unexpecting mouth. The whole class gasped and Mina whistled. 

He pulled back and Deku touched his lips looking up at him with big eyes and red cheeks. “Kacchan… 

“I’ll see you in my dorm room at 7 pm, be there.” 

The whole class stared in silence as Katsuki took his seat like he didn’t just kiss his classmate in front of the whole class. 

He sat in his room at 6:45 with nervous energy about him. What if he doesn’t come? He will… but what if he doesn’t?  

At exactly 7 he heard a knock on his door. He opened it to see a red-faced Deku practically vibrating in place. “Hi Ka-” 

He pulled him in the room and against his chest, pressing a messy kiss on his mouth. It was obvious Deku was inexperienced. Katsuki pulled back and said, “open your mouth.” 

Obedient as he was he opened his mouth and Katsuki swirled his tongue inside, absolutely devouring him. The minutes went by rapidly as Katsuki licked under his tongue and sucked on his lower lip. When he pulled back Deku had a dreamy look on his face and kiss swollen lips. 

“Ready for more Deku?”

Deku was zoning out a little and nodded. Katuski looked down to see his tented pants. Wow, just a kiss and he was ready to fuck. Katsuki grabbed his ass and pulled him close to his chest, grinding their crotches together. Deku moaned beautifully a noise he had never heard but was eager to hear again. He grabbed his other ass cheek and picked him up pinning him against the wall. He was heavier than he was expecting but he managed just fine. 

He humped against him, grinning like a mad man as Deku gasped and moaned, wrapping his arms around his neck hugging him against his chest. Katsuki kissed and bit at his neck and he ground against him. 

“S-stop I’m gonna come!” 

Katsuki stopped and Deku’s rising orgasm simmered down. He panted completely out of breath. Katsuki refused to let that be the end of the night and tossed him on his bed. Deku sat up with wide eyes. “Kacchan?”

“I wanna fuck.” 

“Eep!” Deku squeaked as Katsuki joined him on the bed. 

“Can I fuck you Deku? I’m not doing it if you don’t say yes.”

Deku played with his fingers for a few moments and then nodded. 

Katsuki all but tackled him before yanking off all the clothing keeping them apart. Once he was bare he grabbed the lotion off the table and squirted it on his fingers and thrust into him. Deku hissed so he took away the third finger and opened him up with two. Deku grabbed the pillow and made delicious moans as he stretched him out. 

“Kacchan,” he whimpered. 

Katuski silenced him with a kiss then kissing his chest and his stomach before entering slowly. He was tight as hell so he stopped moving for a second and pet his thighs and his stomach until he relaxed enough to keep going. If it wasn’t obvious before it was now that he was a virgin. He gave it to him and that felt amazing. 

He thrust in and out slowly making sure he stayed relaxed. He looked at him and Izuku nodded, allowing him to move faster without saying any words. 

He moved faster rocking his hips into him making Izuku lose his mind. He guided his arms around his neck and spread his legs farther apart making Izuku cry out and dig his nails into his back. 

He gave up his reservations and fucked into him hard leaving Izuku with no other option than to hold on tight. Izuku came in spurts onto his stomach, but Katsuki wasn’t done. He rolled Izuku on his side and held both of his legs together as he thrust into his sloppy hole. Tears blubbered down Izuku’s face so he leaned forward and kissed them away. His orgasm was rising like a volcano about to erupt. He grabbed Izuku’s body and made him meet his dick halfway for a few moments before Izuku started doing it himself. 

“Deku, Deku, Izuku.” 

Izuku came again with a whimper and Katsuki pulled out coming all over his side. He grabbed tissues and cleaned him up kissing his wet cheeks again before pulling him into his chest. The nerd started mumbling very quietly and quickly but he picked up a few important words. 

“Fling?” 

“Likes me?”

“With benefits?”

Katsuki bit his shoulder shocking him out of his muttering. “Stop muttering. This is not a fling and we aren’t friends with benefits.”

“Then what are we Kacchan?”

“You’re mine.”

Izuku quirked his head. 

“And… and I’m yours.” 

Tears filled Izuku’s eyes. 

Katsuki pinched his nose. “Stop crying, let’s sleep.” He pulled the blanket over them both and kissed him goodnight both of them falling asleep with a smile on their faces.
