This is from the 1976 classic Water Power. It's a lot like Taxi Driver, except this Travis Bickle has a little fetish for forcing woman into doing enemas at gun point. The film is actually based on real crimes committed by an Illinois man dubbed the "Enema Bandit". Anyway he's dead now, so R.I.P you scat-loving motherfucker.
A self induced orgasm leaves her flopping around like a fish out of water. Reminds me of myself when I lost my virginity, except I actually cried a litte. Tears of joy.
