OK, but how does it play in as a fetish? What is the sexual purpose of it?
This is actually a pretty popular by fetish with FemDom's. FemDom's like Bratty Bunny, Miss Minxie, and others have clips where thet hypnotize men to only masturbate to them, or even only get erections for them.....it's all pretty hot stuff. Clips4Less.com has a lot of these....
I just ran into a variation, but I can't assume success.... it only works if you want it to. Cheers.
