I didn't watch the whole clip. I jumped forward every 2-3 minutes, so I might have missed something... what I did see was a loop that was already "pushing the envelope" for what I guess you could get away with back whenever this was made, by having a mixed race threesome, with both a White man and also a Black man fucking a White woman. But then they went beyond even THAT, around minute 18, by having the Black man play with the White man's cock a little, even briefly putting it in his mouth. The White man did not reciprocate. Was that because back in that day, a Black man fucking a White woman was one thing, and a little MM cocksucking was another thing, and you could get right out there on the edge and portray that, but it was still a line you dare not cross over, that a White man could service a Black man?
