try the book black curiousity by Mellisa dubban
My wife has also read this book and it's one of her favorites because it has great sex scenes. However, it's pretty hardcore with revenge, death, ******* and all kind's of nasty mean humiliation stuff in it. Like most books, it ends leaving you saying to yourself "Thank god I read this before actually tried going down this road myself."
She has another book called Black Obsession which is a little bit better but it still has some husband humiliation stuff in it. I'm OK with that but it's been a little too much for my wife handle just yet. Also, it ends with her getting in a car wreck and being bed ridden for months which sounds suspiciously like another bad karma lesson but at least no one dies in it.
If you wife is anything like mine, I would start with
"Sharing Destiny" by Taylor Thomas. It is written more like an actual Romance novel with no regrets and everybody in it lives happily ever after. Best part is it helped convince my wife that bringing a black bull into your relationship could actually
improve your marriage overall.
There is also another book out their that is getting a lot of attention in the Hotwifing community called "50 Shades Of Grey" by E. L. James and they are already talking about turning it into a movie. But near as I can tell, it has nothing to do with Hotwifing. Instead, it is about a dominating husband and an inexperienced wife. Maybe he forces her to sleep with other men, but it doesn't sound like it. Don't know why its getting so attention among Hotwifers.
As far as Interracial Porn movies or sites that she would like, most woman don't go for the visual like men do. Instead they prefer a good story line with character building. It's sort of like foreplay, it's not as fun if you just jump right into the sex. Unfortunately, the don't seem to be any IR movies that cater to woman. You best bet is to get her into reading Interracial Hotwifing novels.
