Warning! Extreme porn! They have some serious sick stuff! They always just feature a small bunch of videos on their main site, but they are all exactly what you are going to call crazy: Drunk people doing weird stuff, girls going crazy for ruined orgasms or strangers joining people fucking in public.

Holy shit! Extreme porn friend and especially scat lovers watch out - everyone else: Get out! Featuring European and Brazilian top models, sg-video.com brings you barely legal videos - mostly scat(Shit 'n stuff). The Triple-X-Network, which includes this and many more sites have one of the biggest and most respected scat-fetish collection of the world!
I wasn't sure if we should list this site in the extreme section or "just" premium porn, but since it is a bit more hardcore than hardcore I've decided to add it here. :) While it is not that bizarre than other sites, you will still see a lot stuff you won't see on other sites like object insertions and even granny gangbangs.
