Polly Frost has put together a very unique collection with DEEP INSIDE. This collection is made up of a wide variety of kinks and she pushes them to their extreme limits by adding in supernatural elements. I found all of the stories quite entertaining, especially:

The Dominatrix Has a Career Crisis
Imagine It
Visions of Ecstasy
Deep Inside

This is the only collection that Frost has out thus far, but I am hoping she releases other books in the future, whether short stories or full-length novels as I'm definitely interested in reading more by her. For fans of erotic horror or sci-fi erotica... I definitely recommend checking out DEEP INSIDE!
