Calling You stepDaddy

You are my stepson and you just caught me sneaking back in from spending time at the neighbor's house, cheating on my husband. I tried to play it off but it quickly becomes clear to me that there is no way I'm getting out of this! And I'm freaking out because I do NOT want your stepdad to find out. What do you want? A new gaming system? A later curfew? Money??? You have other ideas. You want me to become your submissive slut. You want me to start calling you "step-Daddy" Are you crazy!??! There is no way I can do that. But you threaten me with telling your stepfather and I retreat. You start asking me to do things that a stepmom should NOT be doing in front of her boy - showing you my pussy, playing with myself, and eventually sucking your cock. It seems like there's really no way out of this. I may have to become your submissive slut after all.
