Sex in the Stacks

Our library seems to be a real hot spot for those wanting to get their groove on or wanting an impromptu 'Afternoon Delight'.  Is it a fetish thing?  Do they think they're being rebellious?  Or are they just too cheap to go to a motel?  Granted, most of the girls involved would consider themselves 'semi-pros', but I just don't know why a $20 bj seems all the more thrilling when you get it under a table or in the public restroom at the local library.  Call me crazy, but I just don't get it.
