Obedience Cage
The Obedience Cage is a big cage that your Sub lives in. If they do something wrong, you lock them in and laugh at their pain.
She got locked in the cage for not doing my laundry. She had to watch me flirt with my boss while she was stuck in there.
She had to sleep in the cage at night and listen to me talk about my day while she was trapped.
I locked her in the cage while I had my lunch with my friends. She was so hungry, she started yelling at me through the bars.
