I've experienced being put in a humbler a handful of times over the years. I'm a big gear geek and they have never failed to impress me, always putting me deeper into a submissive frame of mind.

Simple, ingenious, relatively cheap and very effective they are one of the BDSM gadgets that really work as advertised.(sadly too many don't) If you are on you hands and knees you will be staying there and if standing you will be doing so awkwardly bent over in a half crouch. In either case any movement will be slow and deliberate, giving the Mistress a perfect excuse to punish you for being slow.

They don't seem to feature all that prominently in session reviews or Domme's media/websites.....and I've had far more sessions where they haven't been used or mentioned. I wonder why that is?
