The night had started off simple enough. You and Katsuki were hanging out in his dorm, sprawled across his bed with some random action movie playing in the background. Neither of you were really paying attention to it, though—not when Katsuki had his arms wrapped around you, his lips moving hungrily against yours, and his body pressed so deliciously close.
