I did a lot of research to fill in the areas that I wasn't knowledgeable about - and I experimented with a few bits, too. Frankly, during my research I looked into some seriously kinky stuff, and in some cases it was frightening. It took me a little while longer than expected to create this series because it kept reading like an essay. I finally got so frustrated I sent it to my editor so she could give me a different take. She agreed, and gave me a few pointers that really helped me step into the mind of my characters.
Only after I put the research away and started thinking about my characters as human did I start really bringing the pieces together. Sure I incorporated my research, I brought in a few of the things I'd read about fetishes - like smells, textures, flavors. But it wasn't all about that any more - it was about the feelings my characters went through as they experienced these fetishes.
I hope I did it justice and lovers of these particular kinks feel respected and pleased.
