Cages ... !?!

I'm going to get a cage for my slave. It shall be her safe place where no harm is done to her ever. She isn't that happy about this idea and says it will be punishment for her. But I think if she gets used to it she will start to like it. It will be her spot, and hers alone. She shall never recieve any true punishment within her cage. We'll see how these things are going...
Oh, and I just started to write a complete slave training. Well writing i propably wrong, I just collected all the information I could find on this topic and created a word document. But it's almost 100 pages right now and it's going to be a lot more when I'm done. I'll try to host it once its ready.
