Darkroom Jackoff

One of my biggest fantasies is getting off in public. Well, one day I was getting ready to develop a roll of film in my highschool photo lab. I was horny that day and I had a huge boner. So a thought came across my mind, why not jack off in the photo lab? So I went into the dark room, and I was the only in there. I turned off all the lights and dropped my pants and boxers to my ankles. I was so hard and came in less than a minute. The cum flew all over my stomach and a little fell to the floor. I quickly cleaned up with a kleenex and finished with my film.
