This is a pretty clever design for a restraint system. It reminds me of a bondage chair, which is always one of my favorite things to be strapped to in a dungeon. They create a great sense of vulnerability, while also allowing the submissive to see the dominant and know exactly what she’s about to do to him.
In this case hanging the submissive on the walls not only removes the need for an extra piece of furniture, but also adds a touch of objectification. It’s not very clear, but I assume there’s some sort of shelf that he’s perched on, so all the weight doesn’t fall on the limbs. Just perfect for some CBT and nipple torture.
This particular piece of dungeon apparatus is located at the Sub Rosa space in Portland Oregon. This image came courtesy of Mistress Viola’s twitter feed.
