Some of the nurses at the clinic were true sadists. They’d slip into a patient’s room once they were safely secured and unable to touch, and remind them just what they were missing. For hours at a time.
The matron didn’t mind, as long as the patients weren’t allowed to cum.
The nurses knew exactly what they were doing. Most of them had once been patients themselves. It appeared to help build the atmosphere the Director felt was most conducive to successful treatment outcomes.
