I suspect that, as ass size increases, the ability to reliably wipe it well decreases proportionally. So, while I have nothing against fat chicks generally, I might observe the no fat chicks rule in this instance. Im not quite sure about exact parameters of width, depth etc, but I would be willing to do some research if someone would fund me.
