My divorced sister has brought her daughters back to my parents' house! As a man in his late twenties, I find myself at the mercy of my daughters, who are more than a decade younger than me. Furthermore, my mother and sister are away from home, so I'm living with my daughters for a week! Just having a young girl nearby gets my crotch going, and seeing me like that, my daughters are amused and try all sorts of tricks to seduce me. There's no way I can keep my sanity in a life like that...
