You are a person of one of the two Genders, you can choose between 4 different characters 2 female, 2 male. And either one will have to live a full week of bad luck that always has to do with their genitals, or anything sexual. Heavy themes of pain or humiliation, and it focuses much more on anal. Unless it specifically does do vaginal every now and again nothing too bad though, but even some comedy. This is a story everyone can add chapters to if they wish.
