Tied down, caged, and teased for hours. This was the reality of your weekends from now on, however your mistress made it clear the cage won't be coming off on the weekdays.
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 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.
