When your partner suggested you try some bondage to spice things up, you never imaged it would start with 3 weeks of chastity followed by a shibari session ending in free use for all your partner's friends.
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.
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.
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.
