As I have some skill at furniture design and building, a local domme of my acquaintance has commissioned the construction of a purpose-built Spanking Bench. We have gone over her needs and reviewed the literature. Her specification includes accommodating male subs of mature age, and sometime ample girth with potential knee difficulties. The current design will be a lightly padded top set 28 inches off the floor, measuring 20 x 26 inches, and a knee support shelf of the same width by perhaps 12 inches some 13 inches lower. The structure will be sized to support clients up to 300 pounds (indeed, I will be proof testing the article with such a load before committing her customers). There will be appropriate restraints and a workman-like finish as this is to be a proof of principle prototype, potentially leading to construction of a finer example later.
Do any of you professionally dominant ladies have further suggestions on form or function? Not being of such a mind myself (For my own entertainment I prefer to discipline submissive women). I am personally unacquainted with the use of such implements to discipline male submissives.
