The thin 18-year-old sister is living in her older brother's house, but she has never paid him rent. Her brother gets tired of this situation and decides to charge her or kick her out of his house. However, he has no money to give her, but he does. She has a spectacular body so that her brother can do whatever he wants with it in exchange for letting her live there for another month. His brother takes advantage of the situation and urinates, does anal sex and everything he can think of to pay off the debt.
