Mistress Serenity is an evil nurse in search of a doctor to try some experiments. Serenity finds the doctor lying down apparently not moving. Mistress Serenity sits on his face in her little nurse outfit. Once the doctor shows a slight sign of respiration Serenity takes off her skirt to reveal a thong and proceeds to sit on his face again. Mistress Serenity stands full weight barefoot on the slave's face.
