A fitness room instructor, a European lesbian with a penchant for dominant play, leads her two eager students in a vibrating threesome. She commands them to strip, revealing their toned, flexible bodies, before passing around the vibrator. They take turns worshipping each other, their moans echoing off the indoor workout equipment. The instructor, her eyes locked onto the students' tender flesh, uses the toy to bring them both to the brink before backing off, denying their release until they beg for it.
