Judging by the interest in this thread and the lack of movies, I am wondering if it would be worth the investment to produce a few films? Probably not., The start up cost would be too high. Still, I am amazed that someone already producing porn has not explored this niche.
I did find two more movies. I could not find a “free” download. But, I did find some links.
Andi Anderson in a "Freak of cock" film is a girl who does not like black people. In the movie she is hypnotized in to lusting for the first black man she sees.

I found another film where a husband hires a doctor to hypnotize India Summer, his shiftless wife. But things go terribly wrong when the black mailman accidentally uses the trigger phrase.
