So you're an anal pro who is looking for a phallic shaped object that you can put in your ass and then inflate? The Inflatable Butt Plug by Cal Exotics may be just what you are looking for. It has a slight curve to it and starts out at a 2" diameter before its even been pumped. This means that you need to be pretty open to large diameter toys to even get started. This thing certainly has the potential for pushing the limits even for the most discerning of size kings or queens.
