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!
