Trying to Cause Rupture with My Knees

Description: This video ime trying to cause testicular rupture with my knees, but seriously trying my best to rupture, only kneeing nothing else but kneeing. i use my kneecap, take a very good aim and nail right in the testicle, to make it be caught between my kneecap and his pubic bone.  over and over and over again, because i enjoy the risk, being wreckless to male genitals is in my nature.
