Sofa casting taboo

You know that your step-mom's dream was to become an actress and you have invited her to audition for your new movie, but in reality your intentions are very different. After she arrives, you inform her that there won't be any special treatment and if she wants to be the female lead, she will have to do EVERYTHING you say, no matter how perverted. She is reluctant, but really wants the role and also she is your mom and she decides to trust you. As time goes by, your requests escalate because you will not miss the chance of fucking your mom. Enjoy ;)
