After graduating I had come back to work at my college, taking over the supervision of the school library. Unfortunately we had a problem with students stealing books and were losing a good portion of our collection. To try and combat the problem I had secretly installed several cameras around the library set up on a timer to take snapshots every five minutes. It wasn't as efficient as a video camera and the chances of actually getting a photograph of the thieves were slim but it was all I could do on the schools limited budget.

I was working late on Friday afternoon trying to makeup some of the hours I had been missing lately when Julie came in. Julie was an ex teacher of mine that I'd always had a bit of a crush on. She was tall and thin, with short dark, almost black hair and a pretty face. She wasn't beautiful but she was definitely pretty, with large brown eyes and large lush lips. Her breasts were good sized, not big or anything but they appeared firm and nicely shaped from the way they looked through the tight blouses she often wore. Her waist was thin, leading down to slightly broad hips. I had always been attracted to her but she was happily married and had a couple of kids so I had just filed her away under masturbation fantasy material.

I waved hi as she passed my office and continued working trying to finish up what I was doing so I could go home. I was so engrossed in what I was doing that I stayed a half an hour later then I originally intended. Glancing up at the clock I swore and jumped up, rushing to clean up and leave. I was supposed to meet someone for dinner fifteen minutes ago. As I was about to leave I heard a small noise come from the corner where Julie had been working. Poking my head around the corner I was shocked at what I saw. Julie was sitting there hunched over the desk, one hand steadying herself from falling, her forehead beaded with sweat. Concerned I cleared my throat and prepared to ask if she was okay. At the first sound she jumped in surprise, whirling around to look at me before she quickly jumped up and rushed out of the library.

Confused I watched her run out of the library then collected the film from the time released cameras and went home, still wondering about Julie's odd behavior. It wasn't until two days later when I developed the film I had collected that I had the first hint of what caused Julie to run out of the library. One of the hidden cameras had been set up so that it took photographs of Julie's back. Examining the pictures closely I could just make out from her posture that it looked like she was masturbating. That would explain why she ran out like she did when I startled her, she was embarrassed at being caught. I spent the remainder of my weekend thinking about what the cameras had caught and what I should do with the knowledge.
