The first time I ever masturbated in public was at the gym. To make a long story short, I was staying with my sister for a few days and at the time she lived with a bunch of roommates. Well, whoever was responsible for paying the water bill didn't do so. Luckily, my sister had a gym membership so we were able to take showers there. Being the horny person that I am I decided that this was the perfect time to have an orgasm or two. It was nerve wracking, yet exciting at the same time. I couldnt help it, I knew there were naked women all around me. I was underaged at the time (taboo?) so I didn't have a toy and of course the shower head was not detachable so all I had to work with were my hands. I tried the classic "one leg bent and raised on the wall" but it wasn't working so well. I ended up crouching down, legs open, knees bent, feet on the ground, so I had access to my goods and if my legs gave out on me my fall would only be about 3 inches. I took my time and enjoyed every second. I allowed myself to breath heavily because I knew no one would hear me through the sound of the water. By divine intervention, the locker room had emptied just in time for me to orgasm twice. I sat there for a minute or so and cleaned myself up before walking out. No one had a clue.
