Conor Coxxx comes home from college, and greets his Step-Mom Madison Lust. He announces he got straight As, and shows her his report card. He reminds her of a remark she made several months ago saying if he got straight As, she would blow him. Madison told him that it was a joke, and that she never thought he would bring up his grades, but admits a deal is a deal. Step-Mom decides to be good example to her step son by following through with the deal they made. She takes him into her mouth, and starts sucking his cock slowly. After a few minutes, she takes out her huge tits and he starts sucking on them. Step-Mom then turns around and pulls down her pants in her step-son's face as he starts kissing her ass. She gets completely naked, and Conor starts licking her pussy and ass as she is bent over in doggy style position on the couch. Conor sits back down on the couch where Madison continues to blow him. After a few minutes, they switch places, with Step-Mom laying back while step-son licks her pussy and fingers her at the same time. They then switch to 69 position. Finally Conor stands up, and Madison keeps sucking off her step-son until he cums all over her tits. They discuss possibilities for future sexual encounters if he keeps getting good grades, as she plays with her cum covered tits.
