There are several sub-plots going on here. Each would make a fine story, however combining them is what makes this a special treat. Most people have several things going on in their lives at any particular point and these folks are no different.
The characters are well drawn, the plot is great and the editing is first rate. This isn't a bondage story per se. It's an excellent story that happens to contain bondage. I could see this turned into a novel. Thanks for sharing this gem!
