A sadistic female doctor ties the patient to a bed and inflicts alternating pain and pleasure under the guise of treatment. The doctor stimulates the patient's cock with a magic wand, making it erect, then suddenly hits him with a whip and tramples his cock with her feet, causing the erect cock to shrink. The doctor stimulates the patient's cock with the magic wand, making it erect, and when the patient is about to climax, she removes the magic wand from his cock and enjoys a tease and denial.When the patient cannot withstand the stimulation of the magic wand and ejaculates, the doctor drips her sperm into the patient's mouth, saying "This is medicine." The doctor laughs as she makes the patient eat her own sperm.
