Gym class was never like this! This week at Frisky-Business Ruby returns and brings a light purple exercise ball with her. Dressed all in red, wearing a sexy bra and panty set, spiked-heels and fishnets with leather tops, Ruby looks like she’s in the mood for a workout! As this incredible photo set progresses, Ruby shows how flexible she can be, as well as how dexterous she can be with her luscious long legs. She moves around in various poses with the fitness ball and you’ll be able to tell she’s had a great workout. At the very least, you’ll be panting!
