Very sexy pics.
I think being in a black man's harem is a very exciting idea and great for role-play. It enables the black man to role-play being a dominant master and the white female of being totally submissive. If there's a white cuck involved too, it enables him to be the beta male and see his white wife/gf submit to the black alpha male.
Of course, I'm not talking of a real world harem where women are ****** into the harem, rather one where all participants enter the scenario of their own volition and leave of their own volition.
