I'm not a huge fan of bondage, but for some reason I do love a good cage. being locked in a cage is total loss of liberty... and if your the female authority who locks someone up, there's soooooooooooo much you can do with your captive little prisoner.
We have an AWESOME cage at home which I had custom built as the bottom part of a very big whipping bench, queening stool, and massage table. We don't much (enough) because it's very big and stored in a place where it's not always easy to access.... but with a little inspiration, it can easily be used much more often... maybe my wife can start getting weekly massages on top, while I'm locked below listening to her moan with pleasure (just a thought). I can think of so many awesome uses for our cage - just look at these pictures to start!
