Chocolate Pacifier
While having sex with a girl doggie style, you put your thumb into her asshole then quickly pull it out and insert it into her mouth. (Just like when a baby sucks it's thumb)
I gave my girlfriend a "Chocolate Pacifier" for Easter.
I caught my neighbor trying to sneakily give his wife a chocolate pacifier.
