I just wanted to pass along a suggestion for a great, quick read as far as a BDSM book called Hot Wife Happy Life by D.L. Caffrey. I'm not sure if this was the correct place to post this so moderator please move elsewhere if needed.

Here is the link on Amazon and below is the book description. Enjoy!

A devoted and loving couple explores not just the simple gray shades of sexual play but also every color of eroticism you can legally imagine.
