Fixed in his straightjacket, the medical gimp will be used to extract bodily fluids from. First I start with a DENTAL EXAM, check for cavities and take a saliva swab. Then I move on to his crotch area, using a PENIS PUMP to enlarge my specimen's cock. I want it rock HARD and he has no control over his dick anymore, whether he likes it or not...I will MILK him with my gloved hands so I have a CUM SAMPLE as well. Then everything can be send off to the lab...
