Sometime in the late 70s or early 80s I remember seeing a movie on local TV that I did not understand (I was a somewhat-sheltered little kid in those days). All I remember is that there were women in the movie who were robots or androids of some sort (perfect human replicas a la Blade Runner), who killed at least a couple of men via sex. I remember one scene pretty clearly in which one of these women had her breasts sort of start spinning like small buzzsaws out of her clothes, killing whatever guy was with her. Another scene I really vividly remember had one of these fembots straddling a man (on the floor, I think, with both of them mostly clothed). The man was enjoying himself at first, "Oooooohhhh, ahhhhh," and then he started to scream and shriek. At the time I had no idea what was going on, but later on when I learned about the birds and the bees I realized that the bot-woman must have killed him with her vagina (something buzz-saw-y like the other chick's breasts).
