I like to think that when fighting Bakugo, Deku will use any and every weapon in his arsenal to win, and when they start dating? Well Deku just sees this as a way of sharpening their skills, so what if it’s un-sportsman like?
Izuku stood off to the side watching Shoto and Sero spar, today was one of the more relaxed classes where no one was using quirks so the general mood was friendly. The lack of loud explosions or ice walls keeping the environment casual. Of course knowing class 1A, this didn’t last long.
“Oi nerd, you wanna spar next? I bet I’ll smoke you in 3 minutes tops.” Katsuki smirked, strolling over to Deku, already knowing there is no way Izuku would ever back down from a challenge.
“Sure Kacchan!” Izuku smirked, a (somewhat) evil idea popping into his head. “How about we make this more interesting? If I pin you down in under 3 minutes you have to make me dinner for a week! And I’m talking fancy dinner!”
Katsuki smirked, also one to never back down from a challenge. “Deal, but if I pin you first, or time runs out you’re doing my laundry for a week, folding it and all.”
They both smiled, before shaking hands. Sero and Shoto had just finished up, Sero very clearly trying to flirt with Shoto (unbeknownst to him.) Deku laughs as they walked off the training mat, wondering if he and Kacchan were that obvious. He stood a couple steps away from Katsuki. The two off them circling eachother. “You gonna make a move nerd?”
Deku smirked, knowing how this would go. The two of them immediately flew into action, Deku aimed high, Bakugo ducked low.
They continued fighting like this for a minute or so. They had long since gotten used to sparring with each other, but that didn’t stop the exhilarating feeling of just being able to move. Instinct guided them, familiarity with one another’s fighting styles.
Deku was getting lost in the action when he remembered the stakes for this fight. A smile appeared on his face without his permission, leaving Katsuki shouting. “what are you smiling for idiot! Only 30 seconds on the clock and you’re not winning!”
Katsukis jab didn’t go unnoticed, Deku knew he had to win. He focused all his energy in pinning Katsuki, he knew this wouldn’t hold him for long, so he got to action.
Before Katsuki could even think Izuku was moving to kiss him. Their mouths merged together, Deku basically kissing the fight out of him. He protested for a second, before all thoughts of fighting immediately left his brain. Why would he care about anything else when his boyfriend was kissing him?
He mutely heard whoops and jeers in the background, their classmates seeing them makeout in the middle of their fight. Bakugo couldn’t find it in himself to care if he tried. That is until Deku grabbed his hands, pinned them above his head, and kneeled one foot on top of him, breaking their kiss without preemption.
Izuku looked down at him, the biggest giddiest smile on his face. “I win! I pinned you down in under 3 minutes!” Deku got up cheering and looking very smug over his hard earned win. Their classmates began walking over, Uraraka laughing with every step.
Bakugo took a second to presses what had just happened before shooting up to tackle Deku. “YOU SHITTY NERD THATS NOT PART OF SPARRING!!” The scariness of the threat was lessened by the smile on his face and the sounds of Izukus laughter ringing through the room.
“K-kacchan I’m sorry!” Deku was squirming under him “S-stop ha- tickling me!!”
“It’s what you get stupid nerd!”
The moment was eventually ruined by Aizawa groaning, and demanding that they never do that in class again, before walking off, most likely to go take a nap.
“Can you make me Katsudon first?”
“SHUT UP NERD! … gimme an hour.”
