Rita Seagrave, Lochai, Hogtied...
I am posting a link to a Hogtied video that does have some nudity, moaning, bondage, flogging etc...so if you find this type of video disturbing, please do not open the link and it IS NOT work safe.
That said, I think that everyone who has an interest in BDSM should watch this video. Rita Seagrave is an amazing (and beautiful) woman. She is a sexual educator who also happens to be hearing impaired; so this is an amazing video that although it is specifically geared toward, playing with the hearing impaired, it explains basic BDSM with simple instructions. So I hope you will watch the video. (A scene is on the front quarter and then the introduction to Rita and instruction starts)
