African immigrants, a problem for Libby?

My name is Libby. I live in the UK with my husband. We were married three years ago. I'm not quite sure how all this happened. I'm an aide social worker for African immigrants. Over the past few months, I have become attracted to many of them. As I'm interviewing them, I keep thinking about the porn videos my husband have watched on occasion. Well, really what I'm fantasizing about are their big, black cocks. I have not acted on any of this yet but the pressure is becoming unbearable...
