Lovely vid, you can see how aroused he is by this, even leaking some precum when she teases him with the superglue..
I do too, I have wondered if it is to do with the little bit of pressure there under the balls.
i'm glad you managed to get the cage back on. Its a very familiar cycle, once unlocked you become less submissive and the longer you are locked...
we have all been in that situation, what i can say it really does get easier, just need to keep trying.
good luck with your journey, it would be interesting
Very similar to my own situation, hope it works out for you
Thanks
