Gotta set the scene. Close group of friends, gone through puberty together with all the ups and downs of that-settled into being 'grown up', but none of us had had sex beyond a little fumblings, fingerings and jacking our BFs off.
For me, I felt like there was this tidal wave of, oh, I don't know SOMETHING, deep in me. It wasn't that I wanted to get laid, I didn't at least not with any of the boys I knew, they were only interested in chalking up as many victories as possible. When I found out that they were also hiding video cameras when they scored, and posting the vids to their mates, AND on the internet that made them just creepy to me.
But still and all, masturbation was fun, no denying that, but somehow, I knew I could do more with it. I just couldn't figure out what.
Until I went swimming one day. As I got changed, I heard the door of the next cubicle go and muffled conversation and a little giggling. That soon became some moaning and then rhythmic bumping of the thin, partition wall. Of course there were holes in the wall where the local perverts like to spy. Well, I guess I must be one, because I sneaked a peek. I couldn't see much, only enough to realise that there was a boy and girl making out next door.
Of course, I was horny in an instant, and took my bikini bottoms off (which was all I had on) and started to masturbate in time with them. There was a lot of movement next door, including seeing her panties almost under the partition and into my cubicle. They were wet too, and I mean WET. Clearly, they knew what they were gonna do on the way there. Looking at her arousal stains, and knowing that right now he was IN her, made me cum.
And that was how I decided to be an outdoor jiller. For a few weeks, I jilled off in changing rooms, at the pool, in stores. I even learned to make JUST enough noise for people to know what I was doing. But soon I learned that the gym is a place where you can cum in public! (Thanks to a marvellous piece of equipment known as the Captains Chair). It makes you swing one leg over the other. Using that, it is quite possible to cum in your panties right there in public.
I even, (although this IS very rare) will sometimes masturbate in the public changing area (female only of course) and kinda dare anyone in there to either leave or watch. It's amazing how many other girls DO just watch, or even join in by touching themselves. One time there were five of us. Only once did a woman walk out in a huff and report me, but she couldn't prove what I was doing and the staff were too scared to confront me I think.
So, outdoor or public/semi public jilling. I wonder are there any more like me out there?
