The act of a female rubbing her clitoris and vagina with a limp penis while the male is unconscious, leading to a chub or full erection.
A girl was horny after reading Fifty Shades of Gray, so she decided to Fun Rub her boyfriend's dick and got off while he was asleep. He woke up with a chub wondering what had happened to him. She was all wet and smiling.
