Under Dog

When a female wears a skirt with no under garments and sits on a male's lap and the male opens his fly and sticks his erect penis into her juiced up vagina. Making it look very casual to the naked eye.

Damn yo, it looked like Mary and Chase were doing the under dog at the local Starbucks/Safeway area.
