Judy's Bloom

The back story (pun?) for this one is pretty easy to set up - guy picks up two crack whores, at least one of whom is known to him, and takes them back to some kind of seedy motel. Guy then demands that they strip before denuding himself (after all, what man in his right mind would get naked before the hookers do) and letting them go to work for a bit. Then our fellow whips out the digital camera that his son-in-law got him for Christmas from that Best-Buy in that mall up near the high school, the same digital camera he used to document the Canada geese that were swimming in his pool (to the delight of the children) this past September.
The single lens unblinkingly witnesses the travesty of the woman's asshole as it turns itself inside out in a simultaneous mockery of birth and excretion. He expresses approval at the rosebud of intestine nervously blooming before his eyes, the other woman exclaims that she's never seen one of those before - but she's game. She has to be, as his guttural susurrations encourage her to toss the salad of the prolapsed anus. Just to make damn sure that everything unforgivable, it lasts for over three minutes. At 1:06 her extroverted bowel utters the saddest fart that I have ever heard - an anguished baritone outcry against drug use and prostitution.
