“Uh kacchan , uh can I ask for a favor?” Katsuki snapped his book closed and hissed “what is it deku?” The boy in front of him fumbled around and whispers something incoherently “HAH? Speak up I can’t hear you dumbass!” The nerd started rambling all Katsuki could make out was “project , need to observe , can I?” He interrupted deku “so for your class you need to observe and analyse hybrids so you came to ask me Jesus fucking Christ I thiught I’d have to murder someone or something!” The green -haired boy looked up witb a hopeful glint in his eyes “so , I-is that a yes..?”
Rolling his eyes Katsuki scoffed and patted the seat next to him “come over here and observe me all ya’ fucking want” a little squeal of happiness made it’s way out the other as he walked over and laid the hybrid down
It was a suprise that being touched everywhere was relaxing the unusual patterns of hands on his back as deku studied his fur patterns had nearly lulled him to sleep , he purred violently when Izukus crooked fingers reached behind his ears and scratched them mumbling about mutations and hearing abilitys
Okay so maybe he liked it a bit too much but hybrids had instincts! And he’d fought most them of but at that moment he just didn’t care , the purring died down at the loss of contact when deku retracted his hands to write down notes , instinctively Katsuki whined and mewed like a cat causing the other to still and then put the pen and pad down he shuffled closer to him and whispered “does kitty want me to continue?” Normally The hot headed blonde would’ve of probably smacked deku for saying shit like that but he was in the zone unable to speak he mewed again the last time he’d done that was probably when he was a kitten ! How embarrassing..
De-Izuku cooed at Katsuki when he made purring noises and buried himself into him , Katsuki looked up from his spot eyes basically black orbs and nuzzled into the others side and soon they both feel asleep .
When Katsuki woke up deku was nowhere to be seen, he groggily got up and called out to him , a green mop of hair popped it’s head round the corner “oh ur up ! Morning kacchan thanks for yesterday” he smiled ,”yeah yeah, what was the class about anyway?” A sheepish smile made its way across his friends face “ I didn’t have a class I just wanted to pet you.. hehe” he spoke and legged it , chasing after him Bakugou screamed “GET BACK HERE YOU PEICE OF SHITTTTT!!!!”laughing echoed the halls they ran down.
A week later
Knock knock , Katsuki basically ran to the door and ripped it open revealing Izuku “sorry im lat-“ quickly he was grabbed by the arm and thrown onto the sofa where Katsuki joined him snuggling up the other with his head in the nook of the other neck he whined “what took you so fucking longgg?” The other chuckled scratching behind the blondes ears “traffic, sorry i took long my kitty” Katsuki nipped the skin
Of his neck and grumbled “whatever ..”
