I've just got done watching Alien: The Director's Cut on the TV, and only now do I realise just how influential this movie is.
Not only does the facehugger itself perform the ultimate face/throatfuck, holding it's victim's head in place while it empties its balls down their throat, but later on in the movie, one of the characters tries to gagfuck Sigourney Weaver to death with a rolled up porno magazine! That's a twofer by anyone's standards!
Thus the entire movie is actually just a giant metaphor for throatfucking. Remember...in space, no one can hear you quack.
