Now that Brody's puckering rectum was more relaxed and stretched out from the pounding I gave him, I decided to reward him with a little e-stim. Dr. Phingerphuck trained me on the device and I was anxious to try it out on this more than willing patient. My dick got rock hard again watching him squirm as I juiced his ass with electrical current. His moaning was satisfying that sadistic side of me. I knew he wouldn't hold out for much longer after I increased the electricity on his prostate and he exploded everywhere. It's good to be the doctor.
