Has anyone else noticed that, if you want to find some good white wife and black dick(s) porn, it's easy--and the woman is usually depicted as a good slut--hot, horny, fuckable, but a decent person; but if you want to find black wife and white dick(s) porn, it's hard to find, and the woman is usually depicted as a "bad" slut--not just sexy and sexual, but degraded in some way?
