I don't consider myself a writer by any means, but I do notice that it takes a few qualities to be able to write smut. One is the command of the language (obvious), the other is an ability to clarify thoughts and actions that seem to defy explanation (see my next quote from you), and lastly the bravery to expose your thoughts to ridiculae or praise. You have those three aspects.
This is what I'm talking about. Yours is the most coherent explanation for me. I'm sure for some of the people on the receiving end of this, it is about breath control/asphyxiation, but on the giving end it's about trust, power and control. And you're right, it is a cycle that feeds itself once it gets going. Making you horny gets me horny which in turn gets you hornier.
I agree with this entire post. The mental power play is the central point. I was very scared at first of hurting her but I don't even have to use a lot of pressure its all about then mind. I like how you guys express these thoughts it helps me to understand my own thoughts on the matter.
