There May Be More To It

My wife and I have an open relationship. As they tend to go, it is far more one-sided, but that it okay because I am into it. My wife has never been with a black guy, but lately has started making a lot of sexually suggestive jokes about the size of black cocks. She doesn't know that that is a huge turn on for me. So whenever she makes one of these jokes she thinks she is making me jealous and a little heated, but I get a little hard.
