Patient arrives at the clinic for his scheduled milking and cum extraction. These sessions are designed to as least pleasurable as possible for the subject. I will be using multiple pairs of gloves, and a condom for part of the session. This insures the patient's frustration, as it doesn't allow them to ejaculate too quickly. And it also prevents contamination of the sample we need. As a requirement, the subjects orgasm is ruined, then collected with my gloves to be sent off to the ab for analysis.
