I have mentioned Forniphilia before as an interesting form of bondage where the submissive is literally turned into a piece of furniture.
I found this attachment, The Human Coffee Table, at a fairly reasonable price. It will cost you 130 USD and you can choose from a couple of different wood types. The table requires that the submissive stay still during the whole time. We wouldn’t like if the beverages or the food on the table end up on the floor, would we now? Some stamina training might be in place before you turn your submissive into a furniture.
This table might also inspire you to make one of your own – Or at least inspire you to let your submissive make one for you.
