This is one of the more interesting and abstract BDSM images I’ve stumbled across recently. I think he’s in what’s technically known as a Gibbet Cage. They were used to publicly display the body of executed criminals after death. Which seems a little pointless, as they were hardly going to escape at that point. I guess deterrence to others was the principal idea.
While they’re striking pieces of equipment, they’re not all that common in playspaces. Probably because it’d be tough to cater to all the different body shapes and sizes necessary. Modern kinksters are a bit fussier about their comfort than your average dead criminal from the 17th Century.
I’m not sure who the domme is, but she’s certainly beautiful and and imposing. The lighting of the shiny latex and metal makes for a great image.
