I have no names of the actors, so sorry, this is going to quite hard. though, hopefully not.
i watched for the first time years ago, and i think it was made between 1979/80-1981. moustaches were everywhere, as you would expect.
anyway, one scene - an orgy of three males and 4/5 females- that caught my attention was between between the male (white) and two girls (one white, one black). anyhoo, he's fucking the black and subsequently comes, as it were. so, after that, he sits there crossed legged and the two girls try to suck him off, which fails. then, waving them away, he says something like "let me show you how to do it." upon which he throws his legs over his head and sucks himself off, coming into his mouth, swallowing.
now, i'm not particularly turned on by this, but i've never seen suck an act of autofellatio carried out in a straight film. it was quite a shock, and i would love to know what it was called for curiousity sake.
any idea?
