Lost Incest story
There is a dad, mom, son, and daughter. Dad is a good looking, nice guy. Mom is a bitch and has let herself go. Son is a lazy asshole, and is not a great catch. Daughter is good looking, and young (but legal). Mom treats dad and daughter like shit, and is fucking son. Mom as I remember has threatened to take everything from husband in a divorce. Daughter manages to set up mom and son to get caught by the police. They get jail/prison time. Husband gets favorable divorce due to mom being felon. Daughter then seduces dad (I think she was also a virgin), and they begin living together.
