Gia Dibella and Summer Vixen, bored gym bunnies, are left to their own devices by their strict, yet sexy coach, Charles Dera. They start working out, their bodies glistening with sweat, but their minds are elsewhere. Gia, with her toned abs and Summer, with her luscious curves, can't keep their eyes off each other. Their workout turns into a passionate make-out session, fingers exploring wet pussies. Meanwhile, Coach Dera, ignored, continues his lesson, his thick cock straining against his gym shorts. He joins in, making it a steamy threesome, fucking them both whenever he wants, turning his free-use wisdom into an anytime-fuck fest.
