You have agreed to take part in a new medical trial. We want to see how perverts like you tick. What makes you a slut for pain? After being tied down by the doctor and nurse you'll have a pleasure probe inserted into your ass to measure how aroused you get from our tests. Electric nipple and ball clamps will be applied to you, and then as we crank up the volts we will see just how depraved you really are! It seems your levels measure off the scale, and your enjoyment of pain makes you a filthy long term study. Such a slut for pain! I wonder how much more you could take?
