Step-Sister Sin is ready to examine her male patient at her underground medical facility. She snaps on her black LATEX GLOVES and tests his balls with clamps, his butthole gets stretched with her metal anal beads before she makes him suck her STRAP-ON dick and starts PEGGING him deeply. He needs a good CUM RELEASE as well, which she performs with a fierce MILKING. He can only obey and follow her instructions and be a good little patient.
