I honestly wasn't gonna post this it sucks, and I made it at 3am.
Dekubaku
"Deku, I'm the one sitting on a literal dick and I'm focused. Why aren't you?!" Katsuki says the annoyance clear in his voice.
"Kacchan. I have an urge"
"Well keep that urge because you're not finished with this page."
"Kacchan please just bounce a little just a little." Deku whines as his hands go to Katsuki's waist.
"No. Now focus"
Deku finished the page and let's just say Katsuki has hand prints on his waist.

Iidabaku
"Are you alright Katsuki?!"
"I'm fine, nothing to be worried about I'm just sitting on your lap"
"No you're not but you could feel pain while doing so"
"I'm fine, can I-"
"No finish what you were doing" the bluenette says cutting the blonde off.

Monobaku
"Kat stay still"
"I can't help it"
"Please focus"
"I'm top of my class, I think you should focus"

Shinbaku
Shinso lays his head on Katsuki's shoulder.
"You're not squirming that's weird" Shinso mumbles.
"Of course I'm not squirming. Do you know who I am" Katsuki speaks writing down an answer.
"Yes I know who you are but Kaminari use to squirm" Shinso mutters
Katsuki turns around to look at the boy.
"WHAT THE F-" Katsuki starts to shout but Shinso Kisses him.
"Kat I'm just playing" Shinso says pulling away earning a glare from the blonde.
