So if you're looking for a wild ride with a kinky doctor and his mouthy young not-quite-a-sub, here's the Smashwords link:
http://www.smashwords.com/books/view/265643
This is a m/m erotic romance, GFY, May-December, kink/fetish, D/s story written in alternating third person POV and it's novel length.
Hope to have it up on Amazon soon, but they don't like free books, so when I work it out, I'll post the link. A Kindle version is available on Smashwords, though.
Hope you enjoy!
