thank you. I believe I've found it, or something very like it. It is tiny, but it's not trying to cage the head, which can pinch badly sometimes. The dilator/sound will be a challenge, but open so a person can pee and cum through it, I like it.
Looks like the 'standard' one. If you look for small cages with urethral insert you will probably find numerous offers of basically this cage. I think it's a pretty mean one! So tiny and with the dilator...
What a magnificent orgasm; I also would like to know what cage this is - and what slides into your urethra to permit an unfettered explosion like this.
