Mom Motivates Son

Mom is concerned that her son will flunk out of high school, after she gets his latest report card she goes to confront him. He tells that he is trying his best but the pretty girls at school are detracting him a lot, since he is so focused on girls he just cant get motivated to try harder. Mom then comes up with a idea, what if she were to offer him some motivation at home to do better? so she says every week he comes home with improved grades on his report card she will give him a little treat. For this week she strips and lets him jerk off while she dancing around naked for him!
