Chapter 1

I want to be an engineer - that’s why I was there. There was an abandoned water treatment plant in the woods where rode my bike. I was fascinated by the pipes and the machinery, so I explored the place - trying to understand their purpose, growing braver as the summer wore on. Eventually I learned how to pick locks and started looking around inside. It was on my second trip inside the big building that I met the girl in the circle.

I wasn’t supposed to be there, of course, but I wasn’t too worried about getting in trouble. The voice I heard - obviously female - sounded at first like someone in trouble. As I followed the voice closer it became clear that the moans I kept hearing weren’t caused by distress, but rather, sex.

I was on a second story staircase overlooking a large machine floor when I first caught sight of her. The sounds were coming from a trim blond woman lying on the cement floor, masturbating. Her skirt was bunched up around her waist, and her panties were down at her knees. She was rubbing her pussy vigorously and moaning loudly. Painted on the floor around her was the outline of a circle, about ten feet in diameter, painted in blue.

I watched, hidden, as she made herself come. I got hard, of course - I couldn’t wait to get home and jerk off - but my curiosity and caution kept me from doing anything about it just then.

After she finished she pulled up her panties, straightened her skirt, and sat up. I wasn’t sure what to do: Sneak away? Approach her?

Her eyes started searching around the room, and she spoke loudly: “Come talk to me? Please?”

So I walked up to her. As approached her, it became perfectly clear that she was a demon. Yes, it’s impossible, but it was the only conclusion from what I saw: a demon in a magic circle.

The demon girl appeared to be a little older than me: probably college-aged. She had straight blond hair down to her shoulders, emerald green eyes, and a stunning slender body. She also had black bat wings and serpentine tail that flexed and swayed as she moved. Her top was a pale blue halter that showed a lot of her belly, and her skirt was a white mini. She wore white high heels.

Instead of being a solid blue line, as it had seemed from a distance, the circle was a dense collection of strange letters and diagrams arranged in a circle on the ground. After years of video games and horror movies, it was exactly what I would have expected a magic circle to look like, except that it wasn’t glowing.

The demon girl stood with her arms clasped behind her, silently, as I walked up. Her pose made her chest stick out and reminded me of how horny she had just made me.

“Hi,” I said as I surveyed her and the circle.

“Hi!” She replied.

“You’re a demon.” I observed.

“Mmm-hmm.”

“And you were just masturbating?”

“Yes,” she answered without reservation.

“Why?”

“Gotta do something to pass the time. What can I call you?”

“Me? I’m James. What’s your name?”

“I can’t tell you that. People finding out your name is how you end up in a situation like this.” She gestured at the circle on the ground. “You can make one up for me if you want, though.”
