It starts with two girl-friends on a rope swing in a lake. Later we see the teen friend at her friends house outside sitting near the pool sunbathing. Her friends dad is watching her through a window. Then her friends mom dies of cancer or some disease. Her friend comes into the room where her friends father is and they start to make out in the room where the dead mom is laying in bed. He starts kissing her legs and continues to move up her legs. The last thing I remember is when the father is looking for his daughter's friend. He is driving down his car in the rain until he finds her and they start to kiss in the rain and he lifts her and puts her on top of the car to start making love.
I have been trying to find this movie for a long time!
