Sage is concerned about her stepmom, Mayara. Although Mayara is in fine shape, Sage still wants to see her stepmom continue to exercise and keep her health in check. Sage enlists the help of health guru hotshot Donnie Rock. Donnie can help Sage and Mayara get into the best shape of their life and keep it that way. But Donnie’s methods aren’t necessarily orthodox. Donnie believes freeuse and sex during exercise are the keys to vitality. So, the threesome gets right to work. Donnie doesn’t hesitate to suck on Sage’s tits during introductions, and Mayara is intrigued by this new approach to exercise. Both women are happy to let Donnie use them freely and follow his guidance. In the gym, Donnie runs the babes through a series of routines. He works out their cores and stretches their pussies all the while. Each exercise focuses on a different part of the body, but the most crucial variable that must remain constant is the dick down. Being used freely is the best way to get optimal results, and Sage and Mayara are learning this the fun way.
