Obedience Cage
An Obedience Cage is a big cage that your Submissive lives in. It's where they get locked up when they make you mad.
She was locked in the cage after she insulted my favorite shirt. I let her out only when I felt like it.
She had to sleep in the cage while I watched my favorite TV show. She cried so much, I almost felt bad.
I locked her in the cage while I went out to eat with my friends. She was so mad, she almost broke the bars.
