In this energetic and erotic creation for Viv Thomas, director Andrej Lupin takes us on a torrid trip to “The Gym.” As the film begins instructor Alexis Crystal is leading two students – Uma Zex and Lexi Dona – through a series of stretches. But once the teacher makes her exit the real workout begins – in the process of eating, licking, fingering and rimming each other to outrageous orgasms both beauties really work up a sweat.
