Write on a member of the opposite sex in chocolate

Robert read the card, "Get out the chocolate, and write a dirty word on the skin of a person of the opposite sex, somewhere where they can't read the word. The ass, back, and neck are great places. If they guess the word, you get to lick off the chocolate. If they can't guess it, they have to wear the word for the rest of the game, or until someone else's forfeit card tells them to do something which allows them to lick it off."

Robert eyed each of the girls, who all squirmed with anticipation.

"Enjoy," said Mike, handing Robert the bottle of dripping chocolate.
