Dirty Shack is a porn tube devoted to some pretty nasty stuff. Put simply, the site's premise is to get you hooked up with a whole new realm of filthy adult entertainment. You'll find shitting and pissing porn both of a straight and gay nature. Whatever your flavor is for a bit of the old bodily fluids play, this site has you covered.
The site updates with new content pretty much on a daily basis. The scenes are also broken down in a few sub-categories so that you can be sure to visit the realms that matter the most. There's also a search function if you want to refine the content down even more.
Dirty Shack also allows users to rate videos, so if you want to get a good idea of how good a scene is before you watch it, pay close attention to what other users have made in the way of analysis. All in all, it's a good place to see some classic shit, scat and pissing action.
