Vanessa is getting her workout on when she sees her lazy stepson Jimmy through her window. She calls him inside to hold her feet while she does sit ups. She asks him when is the last time he worked out and you can hear crickets. So to motivate him she is willing to show him her tits if can do 15 push ups. Jimmy bodies them easily. So to up the stakes, if he can do 50 sit-ups, she will show him her pussy. It was a mountain for Jimmy to climb but he gets it done and Vanessa is a woman of her word and shows him her pretty tight pussy. Jimmy is amazed and now Vanessa is horny from working out or just from the fact she has such power to motivate him. Either way she lets him know he has earned a bonus. She pulls his dick out and puts it in her mouth. After slobbing on his knob, she asks him can she sit on it. Jimmy cant think of anything that sounds better. She rides him and he fucks her back and the real workout has begun. There is certainly nothing wrong with Jimmys cardio as he fucks her in length. Vanessa shows him the benefits of a good work out.
