Have we reached the limit of….shock porn?

After viewing this video http://www.efukt.com/1822_Painful_Anal_Insertion.html I wonder just how much further it can go.

If this girl is acting she is very believable. Why she agreed to have this done to her for a few reais (Brazilian money) is beyond me.

On the funnier side, if you close your eyes and just listen to the video she sounds like one of those formula 1 race cars.
