Kink
kink.com
When you will enter Kink.com you will be notified with a warning where you'll be asked if you want to see straight content, gay or both. I am not here to judge anyone, but I find it more than alright to have this option at your disposal, because for straight men it is not something pleasurable to see gay materials.
On the homepage you will get a big logo with Kink.com and underneath a small letters motto - "Demystifying and celebrating alternative sexuality by providing the most authentic kinky experiences". Office motto and I like that.
It seems that they changed the looks of this website, because a big red buttons allows you to get to the old view. Underneath, you will see big thumbnails for their sites under BDSM / BONDAGE category: DeviceBondage, HardcoreGangbang, KinkUniversity, SexAndSubmission, DungeonSex and more. If you will scroll even further you will get a list of FETISH sites: FuckingMachines, FootWorship, AnimatedKink - and other lists.
You can register a free account but you will need to pay for content: they have pay per view materials, live shows and cams.
The site looks good and if you are into this niche, you are more than welcome!
