Sero was your best friend and you were roommates, he was chilling in his bed when he looked at you and saw that you were putting some lipstick on, sometimes he wondered how did it taste like, so he asked innocently.

—"How does your lipstick taste like?"

Sero asked with genuine curiousity, he indeed wanted to know how did it taste, maybe by applying some in his lips, but maybe things could turn out different.
