This is a fetish known as 'cuckold cleanup'. Usually it involves a closet homosexual who gets off on pimpin his wife out to random strangers. Often the husband will sit in the corner and actually videotape as his significant other gets pounded by foreign cock. Once the creampie has been injected, it's like 'all you can eat' night at Red Lobster. Yum yum eat em up.
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.
This girl shits a massive dildo out of her pussy with no effort at all. If I keep posting shit like this people are gonna think I have a fetish for loose pussy haha.
