Step-Mommy comes into the room looking a bit un-kept and takes a seat on the couch next to where her step-son is sitting and starts to give him a mean attitude right away. She tells him she rules the house because she has perfect big tits. He says he will tell step-dad, but she laughs. He leaves to tell on her and she smiles big. The step-son comes home one day and finds a note from his step-dad that says he is gone for a bit but that he took care of step-mommy. He is told to have fun with his new step-mommy. The step-son is confused and then hears noises. He goes to investigate and sees step-mommy dressed like a slut. She is acting weird and she then tells him that step-dad reprogrammed her and she is now a new robot step-mommy. She rubs her perfect ass on his cock and then grabs his cock. Her new lot in life is to please her step-son. She pushes him into a chair and takes his pants off then gives him a mix between a handjob, blow job, and titty fuck. She then asks if he is ready for robot step-mommy's pussy and he says yes. Step-Mommy stands up and strips naked and then rides his cock reverse cowgirl. She then leads him over to the counter where she bends over and lets him fuck her hard in doggystyle. She finally pushed him back onto the chair and sucks his cock until he cums in her mouth, catching and swallowing it all. Step-Mommy reiterates she is now robot step-mommy and there to serve him. She sits on his lap and he plays with her big tits. Step-Mommy asks if he is pleased with his new robot step-mommy and the sly look on his face tells the tale.
