ClubDom is one of the more extreme Femdom sites and it has a special focus on CBT, although there is plent of other BDSM action too. This is not a playful fetish site. Asses welt and turn serious shades of ouch! Balls are slapped, trampled and punched.
The Club is run by Mistress Cheyenne and she knows how to keep her slaves in line. Along with the standard BDSM action like face-sitting and all kinds of corporal punishment there's some exquisitely painful cock and ball torture. Mistress Cheyenne subscribes to the notion that once you have 'em by the balls their hearts and minds will follow. Torture includes whipping, electroshock, fasteners, vices and good ol' fashioned cock slapping. That's in addition to strap-on banging, forced feminization, feet worship and much more. If you can think of a domination scenario chances are they have done it.
There are 54 photo sets and about 850 movies. They can be streamed or downloaded, usually in a few formats. The best files offer great-quality playback of the brutal domination. The vids come with write-ups that give you a good idea of what to expect and many of the scenes have thumbnails that act as previews by looping clips or giving a photo slideshow. They update the collection on a daily basis, so you can expect to see even more hardcore BDSM scenarios very soon.
This is a great source of Femdom and CBT material. They have some good bonuses too, like POV movies, extra photo sets and an active members forum.
