500 Knee Challenge - Ziva Fey

Description: Martial artist ziva fey decided to take on our 500 knee challenge - because, let's be honest, it's the only way to get some real ballbusting satisfaction. our ball boy was literally trembling with fear, but ziva just laughed it off. so, yeah, ziva easily kneed his helpless nuts 500 times - and you know what? he deserved all the damage she dished out on him. after all, she's a martial artist that loves striking testicles!
