During high school I was part of the auditorium tech crew. We built scenery, set up sound systems, and hung stage lights. Sometimes we worked on weekends, and as chief techie, I had my own set of keys to the building. One Sunday afternoon I went in to finish hanging spotlights for the upcoming play. We weren't supposed to work alone because of safety concerns, but it had to get done that day, so there I was. The worst job was climbing up onto the narrow catwalk to adjust the ceiling spotlights. There were maybe 20 fixtures, each with super-hot 750-watt bulbs that would give you a nasty burn if you brushed against them.
I hadn't been up there for two minutes before the intense heat from the lights had me soaking wet. I pulled off my t-shirt, then my shorts, but the sweat was pouring off in rivers. I kept on working the lights, getting the focus just right, but quickly felt myself getting turned on by my own body heat and the sweat rolling down my belly into my shorts. I started thinking how it would feel to get naked and jack off up there on the catwalk, not exactly out in the open, but right over the stage. I got so excited, it was all I could do to finish the lights, but I made myself keep working. Soon as the last light was focussed, I rolled down my boxers, lay back on the catwalk, and got to stroking. The heat from the lights made it like a sauna up there, and sweat streamed out of every pore of my body. It didn't take long for me to lose control-I was so turned on by the heat and my chest was pumping. I tried to hold off, but the pleasure was so intense that I couldn't stop the explosion. I got on my knees and aimed over the edge of the catwalk. My stuff went flying, thick and hot; I could actually hear the first couple of shots hit the stage floor with a thick splat. My body kept shuddering in the suffocating heat from the lights. I lay back onto the catwalk to cool down. I didn't even try to pull on my clothes; they were sopping wet anyway. I backed down the ladder from the catwalk to the edge of the stage, then slid on my shorts, grabbed a paper towel from the stage toilet, and wiped up the mess I'd blown onto the stage floor. It was time for a cool-down shower, and I also happened to have a key to the football team's locker room. That's another story.
