Ruu is a trainer at a members-only gym where men who boast about their muscles gather, and she has a stronger sexual desire than most. She targets only the muscular members who seem to have physical strength and energy, showing off her peachy ass in risque training clothes and seducing them. After training, she straddles their pumped-up muscle-brained dicks and slams her ass into them, climaxing over and over again! She releases her sexual desire on anyone she can get her hands on!
