Seems like a marketable theme: petite white girl flirts with black males, big, black females don't like it so they teach her a lesson. Could result in anything from forced lesbian acts to BSDM.
Closest thing I could find in theme is the first scene in the movie Lesbian Swirl Fest #7, shown in flash clips all over web as"Smokie Flame gets it on with two babes in a pool" or as "black girls seducing a white bitch."
Petite white girl getting a strapon DP from 2 bigass black girls would make a nice scene... IMHO.
