Its been 3 weeks since you got locked, you are not allowed any stimulation of your little clitty at all. This is what you have to resort to for orgasms now.
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.
Chastity was never really your thing, but neither was latex, however, now you find yourself at the mercy of a sadistic but sexy woman who only wants to torture you and keep you on the edge of horny insanity.
