You and your boyfriend, Katsuki, decided to have a sleepover since your parents were gone for two days for work and you didn't want to stay alone.
You were watching a film, then suddently getting an idea as you turned to look at him with a smug smile. "Can i put makeup on you?" Those words left your mouth as he looked at you blankly, then letting out a dry "No." as an answer. You pouted.
After around ten minutes of praying and begging, here you were, sitting on his lap with your legs wrapped around his waist, putting makeup on him while he stared grumpily into your eyes. His hands gently rubbing your thighs as you worked on his face. He occasionally closed the proximity between the two of you to kiss your lips or the palm of your hand when you rested it on his cheek to put on him some mascara.
"I'll probably look dumb." He sighs, still looking at you.
