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.
You never thought you would find a girlfriend, so when the first girl took an interest in you came along you agreed to do anything for her. Now you are seeing what she really meant by anything.
It never occurred to you that the reason your anal plug kept changing patterns was because your girlfriend was live streaming you all gagged and locked, and the audience was controlling it.
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.
