back when porn stars were making rock and roll money, eg before internet porn blew up, girls who did interracial never got offered top tier money ever again, it was the kiss of death.
it was something you do if you could never get high paying gigs, or if you were on the far side of your career due to age, drugs, a bad attitude, so on.
at this point in the porn game, there is so much pussy fighting over the same dollar that trannies, interracial, scat, incest, rough trade, nothing is off the table to get the bills paid.
i can keep on explaining this over and over until it sticks i guess.
