My girlfriend and I had found two chastity belts in our apartment when we moved in

My girlfriend and I had found two chastity belts in our apartment when we moved in. Surprisingly, they both fit us fairly well. We decided to make a bet. We would hold each other's keys, and the first one to ask to be let out of the belt was the loser. The loser would be the other's chastity slave. Little did I know that she'd done her research, and had figured out how to unlock her belt any time she wanted. It was only a matter of time before I caved in and became her slave. She replaced the lock on my belt with the most secure lock money could buy.
