step-Mom seduces in share bed and stuck in washing machine

My husband went on a business trip and I was left alone with my step-son. He came to me at night because he didn’t want to rest on the couch. Suddenly he began to caress me and when I took his dick I became ready for anything. He started to fuck me but stopped. In the morning I tried to seduce him by getting stuck in the washing machine, but he again said that he couldn’t cum because I was his step-mother. I have one idea on how to make him cum - an Autoblow toy!
