Haha, that seems typical. Rich white woman exploring sexual taboos in her youth, but then makes it big and becomes governor of a hill billy raciest state.
I remember reading marketing studies done by pornography companies a while back. They were doing statistical analysis of porn consumption to determine what direction they need to be going to sell more porn. The highest selling most consumed porn in the US is the "interracial fuck my wife" movies. Apparently, there are a lot of people watching middle age prim and proper white women getting split open by 13 inch black cocks.
