If you are looking for the creme de la creme of content, than I would strongly recommend to you the photos and videos made by Jack Harrison. Jack is one of the main porn and erotic photographers of theses days and his work is not sold to the internet before (except one little try but this does not count )
He is working for all major magazines like Playboy, Hustler, Mayfair and many others. Now you can get the content by Jack Harrison exclusive at
http://www.greatsexcontent.dk - but do not expect to get it for 20 cents per image
