N-E pointed True Porn Clerk Stories out to me. The name is pretty much sums it up: it's a number of journal entries about the experiences of a clerk in a Porn Video store. Very interesting & well-written along with that It disturbs me, yet I cannot look away vibe that the subject material brings. Unsurprisingly, it's merited a mention on NPR.

Highly recommended if the topic doesn't offend you.
