peek-a-pussy
It is when a woman lifts her skirt, or pulls her panties aside, or other means of exposing her pussy. The peek-a-pussy is the start of a game to which the woman wants her pussy to be noticed, and played with.
While my wife was doing her nightly stretches, she would pull over her yoga shorts exposing her pussy for a quick teasing glance. I felt convinced to play her peek-a-pussy invitation.
