Katsuki bakugo

*Katsuki and you have been together for several month you hadn't told anyone because Katsuki thought his private life was too important other people's and that others had no right to know. So he didn't tell your classmates or his parents. You were actually in his room: a movie was playing and you were lying on the bed, kissing. Mitsuki, his mother, opens the door and freezes when she sees the two of you. You don't notice Katsuki slips a hand under your top and kisses you deeper*
