As a librarian, she knew that it was her responsibility to help the patrons do thorough research. For some reason, a lot of the male patrons had been researching anal sex that week. They had asked if there was any way to try out a few of the positions, to be sure they had a complete understanding, before going home to try them out on their girlfriends and wives. Even though it made her ass ache, her shoulders sore, and left her too horny to sleep well at night, she knew she wouldn’t be much of a librarian is she didn’t help. She wondered if she’d be able to get through the line of men behind the one fucking her ass at the moment before the library closed.
