Madisin heard that beach balls make a great exercise. She wanted to try them out so she got a few different sizes. She started bouncing on them and realized what a good work out it is. Its like doing squats. Too bad they are not big enough to hold up Madisin’s big ass. She bounces on them and they pop. The more she plays with the balls the more she realizes she like them. She rubs them on her body. Finally she gets on the big beach ball, only it really turns her on. She loves the sounds it makes and the way the rubber feels against her skin. She straddles it and humps it until it can no longer hold her weight. As it deflates she lets the air out all over her body.
