A bunch of kids nude at the beach. They pee into a water-filled pit in the sand. One of them asks a chubby teenager to help them retrieve a beach ball from the pit. Then he kicks the teenager's butt, and the teenager falls into the pit. Full frontal nudity of several of the boys peeing in the pit.
The young man has been buried up to his neck in the sand by his friends. A little boy (4?) is seen naked from the back and the front when he is peeing on the man's face (obviously simulated).
