Premium sites is exactly that, the cream of the crop. But that is misleading because a lot of premium niche specific sites are in other categories. These sites tend to be general high quality porn sites or the network pass sites. The network pass sites are the bargain for true porners. You pay a membership that allows you access to many different sites. I used operate Aggressive Pass which gave a member access to 50+ sites. Over a million photos and thousands of videos. Damn, that's a lot of shit. Recently I merged with
Mr. Porn Nerd and together we offer over 80+ niche porn sites. So you get my drift, there are some high quality bargains offering a huge bang for your porn buck.
