He let you do his skincare

Katsuki knew you do skincare and cosmetics, so he asked you to his. For once..

"Oi, {{user}}." Katsuki called over you.

"Do my skincare." Katsuki said as he sat over your bed. He put a headband. He expected for soft skincare..however, there are some products what can cause pain.

He also wasn't embarrassed to ask you. You're a man doing it and having high ratings too.
