Black with large cock is our preference, but part of our relationship is humiliation. One way we do this is inviting a variety of men to fuck her to hammer home the fact that other men get to fuck her but not me. This year so far I have had to watch her get fucked by a very obese Hispanic man, middle aged biker completely covered in prison tattoos, and a skinny young gamer geek from our neighborhood. I am required to clean her every time, and the men if they want (she always offers it to them).
She thinks I like the impressive black bulls a little too much, so she mixes in a good number of other men that I have openly disdained in the past.
