The cage had been locked on for months now, you could no longer take it and started signing up on message boards for anonymous meetings in public. You hoped they would give you pleasure and let you cum, but more often than not, you were just a play thing
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.
For two months now you have been locked and forced to ride a dildo any time your partner brought home a partner. As of last week though, you know have to write fanfiction about the events as they are happening.
You knew they were also locked when they asked to lock you up, but you had no idea they expected you to match the time they already had in their belt, and since she was Ace it wasn't difficult at all for her to last the 3 years she already had.
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.
