A brother and sister live with their mother. The brother supports his sister by doing odd jobs. The siblings have a secret they can't tell anyone. When the brother comes home from work, he buries his head under his sister's skirt and performs oral sex when he's feeling weak. This has become a habit. Gradually, the behavior escalates and eventually develops into sexual intercourse.
