Doctor Natasha Sweet is wearing her protective gear while operating on patient/slave Krystal Summers. She starts by applying hemostat clamps to her nipples and labia. In order to hear what's going on inside of her patient, Natasha has a specialized stethoscope shaped like a rubber cock. Once she's determined her orgasm reflex is functional, she dons vibrating finger tips and has her hold her breath while tickling her clit.
