The Chastity Cage - Cuckold Erotica, #31

My wife said she wanted to try new things. She told me it was better if I didn't know what she had in mind. Now I know why. She locked me in a chastity cage and forced me to watch her regular black bull pleasing her while he laughed at me. I thought that was already enough, but I was wrong. Now they want me to clean up and beg for my freedom. The worst part? I'm enjoying every second of it.
