I thought this was a pretty hot variation on a cage design. The outside is a standard cage, which is turned into a box with side panels, which in turn have slots for the shelves with limb/neck cut-outs. Combine it with the right bondage gear and it’d be a highly objectifying set-up. Just imagine the door closing on you and the click of a padlock.
