Cathy is straitening up the house and preparing to vacuum when her step-son Billy comes into the room, he watches his step-mother and is fascinated by her plump round ass. He watches as it stretches the fabric of her pants, and he imagines what it would be like to ass fuck her. Cathy glances around behind her and notices Billy looking at her ass. See something you like? Huh? What..uh no.. no ...uh what do you mean? I saw you staring at my ass....so what, you don't like my ass? “I think you have a fantastic ass! Really, I mean you don't think it's too fat, do you? Your old man said my ass is way too fat...that's what were fighting about right now. He seems to have lost interest in me sexually. Well, take it from me, he's crazy, you are a hot beautiful woman. I think he just doesn't appreciate how lucky he is to have you. Billy, you are such a dear. Cathy leans in to give Billy a kiss on the cheek. After the little kiss they stay close and look into each other’s eyes. They both start to kiss and feel each other up. Cathy breaks away suddenly. She looks at Billy and says "this is wrong Billy I'm your step-mother. I have been since you were twelve!" I know, but I can't help it I want you so bad! They embrace again in a deep kiss. Again, Cathy breaks away. Again, she looks in his eyes. Let’s go to your room, I want you to fuck me! Cathy goes with Billy to his room. She starts smoking a cigarette and gets out of her clothes She lays on her back and tells Billy to eat her pussy which he eagerly does. Cathy begins to suck her step-sons cock making him stiff as a board. She spreads her legs and Billy enters her. He can barely restrain himself from cuming right there and then. He bends his step-mom’s legs way back and starts to pound her pussy. He rolls her onto her side so he can fuck her and get his hands on her big tits. Next Cathy gets on top and fucks him slowly smoking her cigarette and grinding her cunt on his cock. Billy grabs her long blond hair and fucks her hard doggie style. He wants to fuck his step-mother in the ass. The ultimate pleasure for him. Cathy wants it too; she loves to get fucked anally. Cathy gets in position and Billy slams his cock into her ass. Cathy loves it and her big tits are jiggling back and forth. Billy needs to cum, and Cathy wants to taste him. She lets her step-son pop in her mouth releasing a gusher of ball juice. She pulls big ropes of her step-son’s cum out of her mouth
