Penis Parade

Dr Misha is conducting research into male arousal and has persuaded four naked male victims to be test subjects. One by one she calls in the reluctant men and carries out a series of checks on their penises. First she feels their genitalia and compares them to each other. Then she gets a tape measure and records each penis size on her notepad. She then takes several photos of their exposed erections to show her female colleagues before jerking off each guy into a beaker and assessing the contents!
