When a character's pussy sticks out through the leg hole of either underwear or shorts, possible with most any pussy, but easiest when it has protruding portions like a canine_pussy or long labia if humanoid.
Include wardrobe_malfunction and/or accidental_exposure if the character isn't intentionally pulling clothing aside to expose themselves.
