Here's something I've never seen but wondered why. In western and Japanese porn a common genre is the huge black guy(s) and the tiny girl/woman. Why are there not big, black female(s) overwhelming, controling (without resorting to bondage) a relatively tiny white or Japanese girl?
Doesn't have to be lesbian or gang, could be a story like "Gonna teach you a lesson 'bout flirting with my black man!"
