She has only one reason to train her body... to have the best sex ever. Her husband, who is unable to keep up with her monster-like sex life, is having an affair with a young woman who has less muscle mass than his wife. Feeling a sense of rivalry with her husband, she uses her well-trained body at the gym where she works to manipulate several men and cheat on them. She cheats with a different man every day. She seduces him with her big-breasted muscles and has a juicy, meaty sex session where their bodily fluids mix together.
