Among all this talk about 50 shades, I came across the name of an a writer who SHOULD have authored the book: Katherine Heiny. Yes, that is her real name.
http://www.amazon.com/Katherine-Heiny/e/B00MK9VQN4. I haven't read her book of short stories, but it received some decent reviews. No spanking in the stories, though.
Though it's not the way I normally spell it (Hiney), I am only sorry that I didn't think of using it as MY pen name for spanking stories. Then again, it might have been too obvious.
Truth is stranger then fiction, huh?
