Stepmom encourages her to play sports with her and to fuck

This boy doesn't like to play sports and lies at home all day watching his life go by. Your stepmother is worried, so as she likes to exercise, she looks for a way to convince him to encourage him as well. The method he has to use is a bit drastic because at one point he starts sucking his cock. He tells her that it's okay, that if he doesn't want to exercise in the normal way, he'll have to fuck her hard and hard to at least burn some calories while getting his cock.
