I sat on the table waiting for the doctor. A fairly young, male, doctor turned the corner, walked up and introduced himself as Dr. James. He told me that the study would be painless, but that first he had to take my vital signs. We did all the basics, blood pressure, heart analysis, and he looked deep into my throat. The trial was on electrotherapy, and so I figured that it would be pretty interesting to try out. Dr. James asked me to remove my pants and underwear as well before taking a seat on the exam table. Seating down on the edge of the table, Dr. James started to feel my dick all over with a pair of gloves on. After he was done he said he was going to hook up a machine. He placed my balls and cock through this rubber ring that was hooked up to wires.
