One day, my wife returned to her parents' home for childbirth, and suddenly, I began living together with my sister-in-law... I want to have sex with my sister-in-law! But... I can't bring myself to make a move on a family member, so I set up cameras throughout the house to secretly film my young and cute sister-in-law's life for my own gratification... The innocent sister I thought she was is actually a sex maniac!? She's lustfully seeking out my penis...
