The doctor of Psychology gets a real mind bending from Master Len. First she is bound helpless and then her clothing is cut off! A riding crop is used on her exposed parts, Master Len then makes her pull on her own nipples. She is challenged to take as much pain as she can.! Twelve ounces of weight is added to her nipple clamps then she must jump up and down. Electric clamps are attached to her pussy lips and she in made to Zap herself until she can't take any more. Then 20,000 volts is hooked up and she has 5 minutes to escape from the tight rope bondage or when the timer goes off she gets Zapped. This is a real test of brain power and will power. There is a very good interview with this lifestyle PHD as a bonus.
