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 pain of the small cage and a plug that was 2 sizes bigger than you were used to was almost too much, but the pure pleasure you were feeling from the rush of arousal was enough to keep you going forward with your training.
