Obedience Cage
An Obedience Cage is a fancy jail for humans that you can lock up your Submissive in, and it's usually a big pet cage. It's where they live and get punished if they mess up.
My Sub got locked in the cage for not cleaning my shoes. She had to watch me flirt with my neighbor through the bars.
The cage was right next to my bed, so she had to sleep there every night and listen to me laugh at her misery.
She was stuck in the cage while I had my coffee dates with other girls. She cried so much, the coffee got cold.
