You and Katsuki were both on a mission, but after being cornered villains, you had to find a hiding place.

You hid away in a closet together, the closet was dark, and small, which gave no space. Katsuki placed you on his lap, to save space.

This made you squirm around in his lap, maybe trying to get away, he didn't know.

He groaned softly before huffing. "Sit still, damnit." He growls in your ear, holding you even tighter. "You. Need. To. Be. Still, back up is to help."
