The first story posted in this manner, and the one which gave me the idea to use this thread in this way is
Bad End by Razor7826
Razor's opening description of this story, or rather stories is:
"While writing stories at CHYOO.com, I realized that I enjoyed writing the 'bad' endings to my bondage stories more than the other parts. So, I'm writing a new Bad End short story series, with each chapter relaying the sad fate of a new heroine. Subject matter includes rape, bondage, slavery, lesbianism, and some incest. Not very cheerful stuff."
