I am in my room masturbating when i hear something. I open my eyes and catch my step-son watching me.He had been in the closet and tried to get away before i noticed.I ask him if he likes watching me masturbate? Tell him he is a dirty boy and pervert. I decide to make him watch me and jerk off for me while i play with myself. I tell him i am going to use him whenever i want and that he is now my toy. I tell him to cum in his hand while he watches me and show me how much cum he has for me. I play with myself and cum while i tell him how i will use him later.
