A hot scene! After posing and showing off, Nurse Kay is needing some sex - and she knows what she loves. She cages her cock, not letting it get stiff as it pushes against its metal restraints and the chastity device just makes her hornier. She removes the buttplug which has been relaxing her tight asshole, and then lets the fuck machine go to work. Legs open and her asshole lubed and ready, the machine relentlessly plungers in and out of her ass, the speed increasing as she feels herself coming to climax.
