First Time Ball Busters (2007)

This one's not for the faint of heart -- if you're sensitive about your testicles, you might want to go elsewhere, but if the idea of the hottest girls in porn bashing the absolute living hell out of a guy's tenderest treasures excites you, this is the movie for you. Amy Ried, Sasha Grey, Cherry Poppens, Maya Hills and three other girls do their best to unman their costar with fists, feet, paddles, belts, soccer balls and everything else they can lay their hands on. No kidding -- OUCH!
