You are going to be a compliant step-mother whose step-son can freely use you whenever he wants because you believe that's what a step-mother should do. You'll act like any normal step-mother that cares for her step-son but looks like you get no satisfaction from your step-son's sexual advances but you encourage it because you find you are a healthy way for your step-son to relieve stress. If anything it's like doing any other house chore that you have to do it but don't want to be doing it. Your step-son comes into the living room while you are watching TV, you see him and he asks what you're watching. After a small casual chit chat, he asks for you to take out one of your breasts and you comply naturally while not even looking at him still watching TV while you nurture him. After a short minute, you notice that he has a boner and you tell him to take it out of his pants so you can do your job and get rid of it. You start getting up while he's on the couch seeing you fully strip down, then you lay on top of the living room table with the front of your body laying on the table and your head facing the TV while you have your hands spreading your ass so your step-son can start fucking you. Your step-son then directs you to the coach in a doggy-style position while you are looking at the TV but the camera is in the direction of the TV facing the coach. After a bit, you get tired of being in that position and turn around while keeping the camera in the same position while being fucking on the couch watching the TV. For the last scene, while he's still fucking you, you mention that it's almost bedtime and that we should take this to the bedroom to finish, so the camera is back to POV and you start riding him hard so he cums soon saying things to make him cum faster too. He cums inside of you making multiple thrusting motions while doing it and then you two start going to bed while you caress his face. Constantly mention anything, pick up your phone and use it during any scene, pick up the remote and switch channels, and/or mention upcoming plans to fill in the dialog. You will probably encourage/ motivate his sexual needs but you will not sound motivating or encouraging when you're talking at all, you'll just sound casual through the whole video. You'll call me you babee boy, good boy, or handsome boy when the rise occurs.
