That's it! I have found my new place to be! And I don't even like fetish porn! Well, not as much as other porn consumers, to be more precise! BDSMBoard.org is a forum, but I guess that you have already understood that from the word "board" in the domain name. And it's big! There are sections with half a million posts and tens of threads.
Since it is a forum, it looks like any other site of this kind. With a black background that works well on this niche, BDSMBoard will give you spank videos, bondage or femdom clips. In more clean words, anything related to fetish adult entertainment. Right now I see a few hundreds of users online, which means that we are on an active forum. There are millions of replies done in total and almost 10k registered members. In the end, you don't need people, but porn content.
I like the fact that you can run around without a registered username and you can even download the scenes that made you send your wife for shopping. I like this destination, as I told you in the beginning. You can click on the screenshot to see it live.
