Playing mind games with my sub is one of my favorite things! I love to keep my boyfriend on his toes. Over the past few months he's been such a good boy. He's watched me get railed by so many big cocks, and hasn't fucked me once, lol. I wanted to reward him for his good behavior, but still remind him that I own him. So, I let him fuck me while wearing his metal chastity cage. I teased him a bit with my vibrator to start, and then used the vibrator on myself while he watched. I straddled him and slid his cage inside my pussy and told him not to worry and that I would still fuck him in chastity. I turned around so he had a good view of my ass, and bounced up and down him, while his cock strained against his cage. I had him stand at the edge of the bed and he "fucked" me while I was on my back, and then on my front. I made sure to degrade him while he was fucking me to remind him of his inferiority. I let him know I could barely feel anything, and that I was so bored I wanted a book to read.
