Trying to Cause Rupture with My Knees

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.
