When's it stepmom turn?

All of my stepmom's friends are super hot milfs and I knew all I had to do was seduce one of them and I could fuck them all. Much to my surprise, I have done it, I make my rounds in the neighborhood fucking all of my stepmom's friends. Somehow my stepmom ended up in a text group with all of the women I have been fucking and they talk about how good of a fucking I have given them. After finding out my stepmom comes home and sits down on my bed to confront me. I finally admit it and she tells me the types of things the women have been saying. I think I am screwed until my stepmom says whens it stepmom's turn?
