look here's the reality of the situation.
ladies if you have black male friends they should all know what you feel like and if they don't you need to make it clear that they can fuck you if they want to. that it's part of the perks for having a white girl as a friend.
fellas all of your black friends should know that if they pull their cock out and your girl is there she is going to put it in her and that you don't just approve but encourage it.
I'm not saying to go get black friends specifically for this purpose, but when you have one be a good friend and a good wife or husband.
your friend has already checked her out and imagined her fucked, she has already thought about his dick and making him com and the husband has already imagined his wife with another guy. so just go with it
