I had an incredible experience where I came to a city & saw two Dommes who Co-owned a dungeon & were great friends on back-to-back days with full knowledge & some coordination between them.

I did the first session and at the end the 1st Domme locked me into a heavy steel "birdcage" chastity device & left the key for the 2nd Domme, so I was locked in until the next day with no way to access the key. It was not over a limit but it was also completely unexpected & not part of any negotiation (which in that dynamic was 100% acceptable).

Unfortunately for me, my body doesn't do chastity well & cages fall off of me. So, I left the dungeon & went to the hotel room (which was only a couple of miles away) but by the time I got there my left ball, which is small, had already escaped just from moving around (especially getting in & out of the car). This started an extremely slow & very painful process of my full size right ball being pulled through the really small opening.

I tried sitting.. I tried laying down and trying to sleep... but the pain was excruciating for the next 4 or 6 hours (it was 2018 so almost 7 years ago & I don't remember which one it was). But, finally it fell off. Then, came the most excruciating part because I had to text the 2nd Domme to let her know what happened.

The next day I woke up when the 2nd Domme texted me saying it was ok & that she wasn't surprised. So basically, I ended up being tortured all night (first by the pain then by the worry of my failure to keep it on). Which both Dommes took a great measure of sadstic glee in after hearing the whole story of what happened.
