Meeting my step mother's very special needs

You catch your step mother kissing some guy an old friend, she says in the bedroom and you want to know what is going on. She wants to know how much you saw, but more importantly, she wants to know what it will take to keep you quiet about what you just saw. You follow her to the bedroom and begin the negotiations. Simone confesses that her relationship with your step-father is a little strained, but that she loves him very much. As a woman, however, she has certain unmet needs. She is lonely and you understand that. In fact, you kind of feel sorry for her. You have needs, too, right? Yes, you do. You are a little jealous, though, because you think that you should be the one meeting her needs, not that friend of hers.
