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.
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.
Signing up for a medical kink weekend was on your dream list. The chastity belt was a nice touch, but the full denial was starting to really get to you, you cant remember the last time you went longer than 12 hours without orgasming.
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.
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
