My father remarried and I got a young and beautiful stepmother. Plus, there are super cute high school sister twins! Then my father starts engaging in borderline sexual harassment with the step-sisters! Meanwhile, I peek at my father and stepmother having sex every night and masturbate! One night, the sisters show up to peek and are shocked, and when my father notices, he says, "There are different forms of family," and shockingly starts having sex with the sisters! I, on the other hand, am pulled aside by my stepmother who says, "You've been watching us every night, haven't you?" and thus begins the forbidden incestuous orgy within the family.
