Ruu, a trainer at a members-only gym where men who pride themselves on their muscles gather, has a stronger sexual desire than anyone else. Targeting only muscular male members who seem to have physical strength and energy, she seduces them by showing off her peach buttocks in risqué training wear. After training, she straddles the pumped-up penis and hits her ass repeatedly to climax! I will release my sexual desire at random!
