I assume that you all watched Season 2 of The Janice Dickinson Modeling Agency as religiously as I did, and so are already intimately familiar with model T.J. Wilk and passingly familiar with his naked butt.
Since the show, he has done a nude photoshoot with photographer Tony Duran for some purpose or other, and the shoot was captured on video! See stills of T.J. in action after the jump, and download the video if you like [NSFW].
