My hot stepmom wants revenge

I don't know what to do. Should I be on my father's side or on my step mom's side? She is only my stepmom but I think she is right on what she is doing. I find it reasonable that she is mad at my dad for what he did but I don't know if I should help her get her revenge. Of course, I'm not biased because she is hot or anything. She is a hot busty MILF with blond hair and the best body I have ever seen. But she wants to fuck me to get revenge on my father. I can't lie, her tits are amazing and I wish I could touch her boobs. Imagine fucking my step mom's pussy… Maybe I'll fuck her this time if that's what she wants.
