Yoga-panted Cathy Heaven receives an intense, oily massage from her students, but things quickly escalate when they discover her insatiable fetish for fisting. Her big ass and pussy glisten as she's tied up, allowing her students to take turns roughly pumping their fists into her gaping cunt, hitting her G-spot and making her squirt. Cathy's pussy is so wet and sloppy, they even manage to fist-fuck her deeply with their toes.
