I am an author looking for inspiration to write a Femdom story.

I am a young writer who is trying his hand at erotic literature. The sub/Dom relationship interests me sexually, although none of my partners up to this point have been very enthusiastic about the idea. This means that my only inspiration for writing such a story comes from pornography, which can only go so far.I am interested in anything that people have to tell me, although I do have a few themes that I would like to play out in the story. For example I would like to hear from subs some of their thoughts before, during and after sex and to find out at what point excitement and sexual frustration is at it's highest. I also would love to hear from Dommes because I have almost no idea how to write a character that is rounded and authentic because I have never really met a Mistress. PMs welcome I work from home so will be on for the next 10 hours.

Possibly the easiest way is to read other authors' femdom stories.

You could search for the tag 'femdom'.

Or you could try some of mine, for example my Shelacta series starting with

Or some of my Flawed Red Silk series:

Hi, welcome to Lit.

You could browse the BDSM and Role Play forums.

Like Ogg, I have some femdom stories if you want to check them out...my Marion series and The Bet.

Thanks for the suggestions Ogg and Jo, I will certainly take a look at both of your stories.
I must be honest and say that I have found other peoples' work great for style, format and the development of themes I hadn't thought about, but for my current purposes a real person who can share their mindset and motivations would be better.
