There is something I have often pondered ever since my first chastity belt was put on me. The sound of a clicking lock!
I suppose the sound lasts only a few hundredths of a second yet it produces a very powerful effect on my emotions. Early on, Angela, my partner, noted that it had a profound affect on me and would ask me what it felt like. The best I can come up with is that if is a bit like the rather pleasurable sensation that you experience when you tense up all your muscles for a few seconds and then suddenly relax. And in a way, that is sort of what is happening. When the locks is unlocked you have control. You are responsible. The weight of responsibility is with you. Yet, in that instant when the lock clicks, that weight of responsibility is lifted. You can relax since your lover (well for me its my lover who I trust absolutely) has now taken control and assumes that responsibility for you. In a perverse sense, it like the sound of freedom - freedom from responsibility.
Over the years it has also become obvious that Angela also like the sound of the clicking lock. She says it is because every locks that clicks, just means she has connected with me even more and that she loves the way I trust her and the way it binds us together.
For most of you locked against your wills, I imagine that most of what I said above makes no sense. I am so sorry for you that you miss out on this little pleasure of life. It probably only works when it involves your lover.
