Talk about having to be limber.
It is about sucking yourself off, and while the pictures are more of an artistic layout, it is rather interesting to view. I mean it brings new meaning to the concept of being serviced, that's for sure.
There was a forum, but spammers ruined that. There is a blog, a video chat service and even a video on demand service, listing naturally self suck videos.
For those into this, or curious, its rather intriguing.
