Step mom is a porn actress. Brenda James

I've been avoiding my step mom like the plague. How am I supposed to conceal the fact that I saw her in a porn video? She carries on around the house as if she were a typical suburbia housewife but I know better. It doesn't help that I get a raging boner just thinking of her and what I saw her do in her movies. My step-dad is one lucky guy for marrying her. I wish I could get a piece of that but she is my step mom so I'm sure anything sexual with her is out of the question that is until she cornered me in my bedroom today. As we started revealing her other identity it became apparent that my step-dad doesn't know what she does for funds. She wanted to keep it that way by offering me a hand job as she talked dirty to me like she talks in her porn movies.
