Work Text:
Izuku and Katsuki cuddling with each other on the couch in the living room of the Midoriya apartment. Mitsuki and Inko walk inside after going to the local convenience store for some morning breakfast.
“Hey Mom,” Izuku calls from the couch.
Inko laughs, “Good morning lovers.”
Mitsuki chuckling behind Inko. “Yeah, I guess dorms may not be the best place to ‘hangout’ with each other. But please at least try to keep quiet, or see if the room is soundproof.”
Smirking, Katsuki asked, “Ok… but what if the room isn’t soundproof and I want to hear him?”
“K-k-kacchan!?” Izuku studders, blushing bright red.
“You know what if I just soundproof Izuku’s room for you two,” Inko suggested, “that sounds good? Right?”
“Eh? Nah. I’ll just tell you if I want to fuck you son.” Silence. For a long time.
“Ok who’s top and who’s bottom?” Mitsuki asks to break the silence.
Izuku, who’s still slightly red, “Oh, there is no defined one. We alternate. That’s because he likes to sit on my lap and bounce sometimes if he’s feeling happy. If he's angry, I can forget walking for a few hours,” he finishes realizing that he said too much.
“Deku! What the hell! Let’s go! Back into the bedroom,” Katsuki yells.
“But I’m hungry! Kacchan!” Izuku exclaims.
“You can eat in the bedroom!” He says, pulling him by the wrist to his room.
“Wait! What do you mean-” Izuku says, stumbling over himself.
*A few minutes later*
Their mom hears Katsuki moaning. “Well, I guess Katsuki is bottom right now,” Mitsuki giggles.
Inko rolls her eyes at her friend's antics, “Yeah, I guess. Can you imagine what will happen after they move out of the dorms and together alone?.
“Oh they be fucking!” Mitsuki says with finger guns and a wink. Inko just sighs and thinks, ‘how did we become friends again.’
