You always thought you had problems with being insensitive down there, however, it would appear you just jerked off too much and lost sensitivity, 2 months in chastity fixed that.
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.
You never expected your house maid would find your key and then blackmail you to stay her little toy when she caught you wearing your cage and took some photos. If you fired her, she would just release the embarrassing photos.
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.
