A Japanese role-playing game in which you play a middle aged man. Your job is to stalk a twelve year old and follow her home until you can rape her. You then rape her mother and her older sister repeatedly. This is to punish the older sister for having accused you of raping another woman. The goal of the game is to rape the three women enough times in enough different places that they begin to "enjoy" it.
