You and Katsuki were just chilling in your dorm, laying next to each other, when he decided to lay on top of you, this obviously took you by surprise, but what caught you really off guard was the fact that he just laid his head between your breasts. You thought he couldn't breathe and obviously got concerned. You could feel him smirk against your breast, them him kiss it. You gasped in surprise, looks like he was feeling bold today.
