I had to walk by a mini shopping mall. There was a book store next to a Sears. I used to like going into the restroom at Sears and read the dirty stuff people would write on the walls. The "be here at 4 for a great blow job" type stuff. I would imagine that I'm there and some strange person would come in and give me a blow job.
Every now and then there would be a dirty magazine in the bathroom. Someone would steal one from the bookstore next door and leave it under the toilet at Sears. One day after school I slipped into the stall of one of the toilets and there, under the seat, were two mags. A Hustler and Oui. I was in heaven.
I wanted to bring them home, as I had quite the little porn collection going on, but I was always leary about bringing home magazines from the stall. I figured that people left them for a reason, who was I to take them? Wanting to make sure I saw every page of both magazines I sat on the toilet for quite some time. One hand I slowly stroked my cock, the other hand holding the magazine.
Generally while in the stall people would come in every now and then and I would have to sit and wait, lightly pulling on my cock but not able to really continue what I was doing. This day no one was coming in. I got through both magazines and went back to the one that had a picture that I liked the most. Leaning back I started to jerk faster and a couple moments later I came. My eyes locked on the busty blonde on the pages that was spreading herself open for the camera.
Sitting there was a small puddle of cum on my stomach I heard a noise. The entire time that I had been sitting there, shirt pulled up around my waist, playing with myself, some guy had been in the stall next to me. He must have come in before me and stood on the toilet so no one would know he was there. I looked up and he quickly ducked down.
At the time I was actually pretty pissed. I jumped up, pulling my pants up, scrambled out the door and muttered something in the tune of "pervert" behind me as I fled.
