Click sound is really great when she is who closed it..but unfortunately...i did myself..so she just take the key...
In my case mistress slams the key lock shut. Both the key and the tool to get the tether out are in a very solid key safe which she can unlock remotely or while she is there. She deliberately slams it shut then gives me the look at it closes. She never says it actually make her tingle. I think when she paddles me that might be more likely.
It depends on my madams mood, some times she loves to look me in the eye as she closes the lock, other times she like me to lock it my self to show my commitment to her.
It was a now ex of mine that bought me/us/her a Fort. All metal all shiny she had not told me she had ordered it meaning it to be Bday surprise she said. When it arrived she got that giddy she texted me and had me come over to hers that night. Cutting a Long story short closing the the lock gave her an orgasm. Subsequent lock closures always invoked a very big smile. She loved locking me up thats for sure.
I don't allow many unlocks at all, so I forget what having the lock clicked shut feels like... I know I like it locked and secure. I get my 'thrills' by having my pets service me regularly with obedience and utmost deference, which I do enjoy.
...perhaps one following the other. as she toasts her triumphs and the night to come. just … confabulating. : )
Every holder I've had, in person or remotely, has started off not mentioning it, but after focusing on it, has indicated a very strong interest in hearing and seeing the lock click shut. Their response to it, each slightly different, but clearly enjoy it! Those online have made it clear that any time I have an opening for hygiene or reward, that if nothing else, I am to make an up-close and clear vid of it so they can savor the moment. For me, I enjoy chastity, and like the sound myself, but it promptly puts me into mental chastity and the sound tends to linger and echo for quite a while!
