You're mistress knew all she ever had to do was talk about touching you and you would get hard and feel the endless frustration of the cage, however, on certain days she would take down your panties and rub herself against you cage. It was almost enough
First you wore panties, then you dressed up, now you are locked in a cage that you lost the keys for and there is only one way left to feel release. Let's hope you are a fast learner.
