Soooo, I just found a video while... browsing the internet.
It is actually a gangbang video from the set of jackass.
Seems they hired a hooker, and let everyone have their fun.
Chris pontius features a couple of times, fucking and cumming, right at the beginning and again towards the end. Even shows his face @ 30:52.
There's a few other familiar faces during the video, but the cameraman avoided showing most peoples faces.
Its horrible quality video but I dont know how its managed to lay low for so long. Even the uploader on the site I found it didn't realise how much of a gem they had!
