Dr Inka has her patient strapped down to the bench, nipples and cock exposed, ready for her cruel experiments. She uses elastic bands and electrics to zap his cock, the Wartenburg wheels adding extra spice and making him moan. Inka controls his breathing as she uses rods to stretch his cock, as the Erostek helps with extra stimulation. Finally, she uses a vibrator on his excited dick, extracting a full cum sample from his cock to feed back to him.
