Rim Your Mean Step-Mum Or Become Homeless

[This was a custom request] You've found out that your Step-Mum is cheating on your step-Dad, so you approach her about it. She acts completely blasé, as she explains that you're right. Your step-Dad knows all about it and lets her fuck other men. He's so pathetic that he knows she's the best she'll ever get - so she cuckolds him and makes him clean up her cum filled pussy and arsehole afterwards with his tongue. Now, you have a choice - to either go along with this sordid agreement or pack up your bags and leave. Your step-Dad would never pick you over her, you're just as pathetic as him. She begins to cruelly humiliate both you and your step-Dad, accusing you of wanting to fuck her too. In fact, she's going to prove it by making you lick her arsehole right now. She slips up her dress to show off shiny nylons while still insulting you. She wants you to call her Mummy as you tongue her arse. She bends over in front of you and spreads her cheeks, pressing her arsehole right up against your face and encouraging you to eat it. You have no choice - you begin licking her little button hole. She admits that it may taste of cum as she was fucking some of her co-workers earlier. She wants you to experience exactly what it's like for your pathetic step-Father. She even tells you more disgusting stories about him as you work her arsehole obediently with your mouth. She starts to praise you a little for doing such as good job as you explore her anal cavity as deeply as you can. She knows now that you're exactly as pathetic as your dear old step-Dad. She starts to lightly rub her pussy, encouraging you to eat it more and push deeper until her asshole twitches around your tongue and you know you've made her cum. She tells you that maybe you're a good Step-Son afterall... just like your Daddy. Both her pathetic little bitches now, with no escape.
