I had promised my step-mother that the next time my father when to work during the weekend I would stay at home with her, so we could catch up and put the sex on schedule again. I've been avoiding my step-mother since my dad told he's suspicious she's cheating on him, the doesn't have a clue it's me. I didn't tell my mother about this and she now thinks I don't want to fuck her anymore, what isn't true. I do but I have to be more careful. She stopped talking to me so I had to make things better.
