Stepmother meets the penis step-son to keep the secret

I Know that my father is an idiot and behaved badly with my stepmother. Then when I found out that you scopava another man, I was not surprised. Although I must say that I was jealous. My stepmother is very sensual, beautiful and intelligent. I would like to have the opportunity for my father. And now that I know his secret, I thought that I could use this information to my advantage. I said that I knew that you scopava his friend, but that would have kept the secret in exchange for a blowjob. I wanted to become his replacement, the cock he needs, when my father is no more. And that was the first step. When I purposes more often, it will be understood that my cock is enough for her.
