Dr. Zia Cristal is taking care of a sore spot Randy has in his crotch. She soothes it with her mouth, but that's not quite enough. The doctor needs to take more extreme measures, so she disrobes, lets the patient suck her cock for a while, then tries putting Randy's throbbing dick in her ass. She encourages him to thrust it back and forth until the pain is relieved. He follows doctor's orders and leaves a big cum wad on her face and chest as proof he's cured.
