You come home after a long day, and your step-Mom is making cupcakes for you and your friends. Earlier, she brought you lunch, but she was in her outfit for yoga, and all of your friends were calling your step-Mom a MILF, embarrassing you and telling you how they want to fuck her. You confront your step-Mom about it, and she laughs, kind of happy that she's considered a MILF. When she gets back later from yoga, you are still sulking about it, so she tries to comfort you. She promises not to dress too showy around your friends, but she wonders why it bothers him so much when they talk about her like that. She says he is attractive too, and that there is not a reason to worry about her getting hit on. She suddenly comes up with a very fucked idea, but she thinks that maybe if she has some fun with you, that your friends won't have anything to make fun of you for anymore. She wants to be the most loving, sexy step-Mom in town, and the way to do that is to fuck her own step-son. She gets your hard cock out and starts loving on it and sucking it, kissing it, calling you her sweet boy. She loves you, and she wants to show you how much she loves you. She then straddles you, slipping your cock into her tight pussy, and rides you, letting you feel her wet, MILF step-Mommy pussy. You say you have to pull out, but she doesn't want you to. She wants you to fill her up, fill your own step-Mother up with all of your cum...
