At around 15 pages this is only a very quick read but it's a great introduction to the author's Madame X School of Sex series. If you're looking for a fast but steamy read and don't mind reading about a voyeuristic encounter between two strangers then this could be just what you're looking for. You'll be able to finish reading it in less than 10 minutes but for a freebie it is a good way of deciding if you want to carry on with the series.
The kindle version includes excerpts from the next book in the series and from several other stories by both authors. It's a great way to try before you buy and I'm planning on buying at least a couple of the stories to find out what happens next.
Don't pick up this story expecting a full length novel or even a novella or you'll end up disappointed but for what it is I found it an enjoyable read.
