Okay i might be a little slow on the up take but is this a new fad in porn?. Before the guy blows he gets the awaiting girl on her knees to punch him repeatedly in the balls as hard as she can?. I hope this is a one off, heres a clip of keri sable in full ball punching form, second clip (please cut and paste link instead of clicking directly in case it takes you somewhere else)
