In the heart of Chicago's Southside, a stranger's late-night prowl leads him to a dimly lit alley, where he finds a hidden, grungy glory hole joint. Stepping inside, he's greeted by a wall of anonymity and the scent of sex and sweat. He unzips, and a warm, eager mouth envelops his hard-on. As he fucks the faceless pleasure-giver, he hears muffled moans, knowing others are getting off nearby. The unknown turns him on more, and he pumps harder, wasting nothing until he spills his load into the waiting mouth.
