Nurse McQueen calls in the patient, he's been referred as he has been masturbating too much. Nurse McQueen is a specialist in treating cases like this. As the patient is sat naked in the seat (for extra humiliation) Nurse McQueen pulls out a Kali's Teeth Chastity device. Not only is it a chastity device, it is fitted with spikes on the inside. The harder the cock gets, the more the spikes dig in and the more painful it is. Nurse McQueen demonstrates just how painful it's going to be for him to masturbate with it. She then locks him up and sends him away for a week. Will the pain stop his masturbation habits?
