My boyfriend has been such a good sub recently, I wanted to give him a little reward for all the time he spends locked up for me. I teased his cage with my fingers and got him super desperate. I took of my key necklace and dangled it over his cage, taunting him with the possibility of freedom. Then I made him beg me to unlock him. Once he was unlocked I started stroking his cock. It didn't take long for him to get nice and hard for me. I told him that even though he was super hard, his dick is still useless to me, and that all that he would be allowed to do that day was rub himself on my ass. I flipped over so his pathetic dick was against my ass, and he started grinding himself on it. I taunted him by reminding him that he is pussyfree and that he would just have to imagine he was fucking me. He became super desperate with all my taunting words and that view of my amazing ass. He was so hard and it was so funny to hear him beg so desperately to fuck me. He rubbed his useless cock on my ass and begged to fuck me. Obviously I told him no. Then I began to grind my ass on him, which drove him crazy! I could tell he was getting too excited so I locked him back up and told him better luck next time, lol.
