Warning! BUY this clip if you love my sexy ass busting nuts!

My step brother thinks just because he took some karate lessons that I can't still kick his ass. Luckily I've been withholding my most powerful moves. He immediately drops as I knee him in the balls. I put handcuffs on him so he can't protect his poor helpless balls and proceed to beat some sense into him. Now he knows that no matter how big and strong he gets, All I have to do is hit him in the balls to make him go crying to step-mommy.
