Looking for ideas for erotic books

I have several books now available at Amazon.com in the kindle store.  Most of them involve female dominant themes and some include boot worship.  I like to write about things that other authors do not include.  If you have ideas that you would like to share with me, please feel free to do so.  My email address for suggestions is bootslover4u@yahoo.com

Here are some links to my present books:
