Most of my BDSM bondage interests and experience have centered on leather bondage gear but I recently saw a short video of a Domme who had a sub in heavy metal bondage (Very thick collar, wrist and ankle cuffs all joined by heavy chain). I think she mentioned that he was in something like "30 lbs of irons"

The ankles cuffs were joined by a short hobble chain and another chain connected up to the collar with the wrist cuffs secured to it above the waist. That chain was short enough that the sub couldn't stand fully erect but had to crouch. She was forcing him to move around the dungeon doing "chores" and was encouraging him to go faster by frequent use of a cane.

For some reason I found this scenario very hot. An Etsy search found lots of artisans offering some beautifully crafted heavy metal cuffs and collars. Certainly not cheap but they appear to be very high quality.....

Anyone have interest in this sort of thing? I imagine being locked in some of these would become quite challenging quite quickly.....pretty much punishment and restraint at the same time!

Dommes, do you much metal bondage gear and get much call for it or is it a fairly unusual interest?

I recall asking about a metal stockade and Mistress Tissa saying she had one but rarely used it as most subs found it too intense. I wonder if this sort of thing might well be the same...
