The stepfather is at the mercy of his daughters, who expose their defenseless selves after a bath! The stepfather is on the verge of falling for the daughters, who will do anything to break up with their mother! "It's okay if your mother isn't here. We'll do everything for you," the daughters say, and they do more and more naughty things. He tries to persuade them that it would be bad if their mother found out, but they don't listen. In fact, they get even more extreme! It's true that the daughters are more attractive than his aging wife, but... I feel like this is wrong for a father. But it's too erotic!
