Little Johnny came home from school one day and went by his mom's room. The door was open, so he looked in and saw his mom lying on the bed naked moaning and touching herself saying, "Ooh, I need a man! I need a man!"
The next day, Little Johnny got home from school and saw his mom lying on the bed naked with a naked guy on top of her. So Little Johnny ran to his room, stripped down naked, and started to touch himself, while moaning, "Ooh, I need a bike! I need a bike!"
