The hard plastic cage covering your privates didn't let any sense of feeling through, but for some reason you tried to still tug on it even if you knew it was a hopeless endeavor.
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.
These days the girly looks and the cage were just part of the normal attire your mistress expected of you, however the leaking in the cage that was constant, was punishable by a whip, cane, or longer sentence. It all depended on her mood.
