This scene (sc8) is from a film called Satisfiers of Alpha Blue (1980) (aka The Satisfiers of Alpha Blue). Its a gem of a film and is still a top film for me.
I had this on a VHS collection with 4 movies, been trying for years to remember the names of the other movies. Only trace I ever found is someone else looking for the same thing lol.
So what is the point of interrupting the action just to show a close-up of the guys face? We are guys jerking off to Lysa sucking cock. Our fantasy is that it could be our cock that she's sucking. So again I ask what's the point of showing me, a heterosexual man, a close-up of another man's face while I'm masturbating? It's gay enough that the scene has more than one cock in it.
