I have submitted several stories here most of which include some form of public masturbation, and mostly on buses. However this story differs in several ways. Firstly, it's just outside, i.e. not in a bus and secondly, I get caught.
A few years ago, when I was around 18, the day began as any other, I woke, etc etc and it was a generally boring day as I was off University and had zero to do. I decided around midday to go for a walk into town. On the way I started looking at places at the side of the road pondering on whether or not they would be good wanking places. Good in the sense that they could give me the sensation of people watching/having the ability to see me whilst not actually giving them that opportunity. I spotted several such places but continued on my walk.
However, as I thought more and more about it, I got harder and harder to the point where it started to hurt. I then decided to turn back and find one of the spots I had seen earlier.
Once I found the spot I climbed off the road and pulled my penis out and started stroking like mad. I wanted to extend the pleasure so I immediately slowed down. After ten minutes or so, and after countless cars passing by without a single beep or any clue as to their discovery of me, I decided to take it a step further.
I took off all my clothes, laid myself on the ground, legs spread wide, facing the road and started masturbating again. Five minutes later and several cars later, I was really getting into it and there was a stream of precum all over my hand now, when all of a sudden I heard a female voice go. 'What the hell do you think you are doing?' I was mortified! It was my next door neighbors daughter. She was about 16 and even though she wasn't the prettiest, she had a decent body.
I scrambled to cover myself but I was at the side of a road naked, masturbating, there wasn't much I could do. I just said sorry and that she should forget it. She refused and asked what I was thinking. I told her the exact reason as to why I was there and she simply accepted it. What happened next though surprised me most.
She basically said that 'since we can't get caught we may as well take advantage of the situation. I finish you if you help me out?' I said grand and she climbed up off the road, joined me and started stroking my penis. After I blew my load, she stripped off and I started fingering her. We helped each other to multiple orgasms and we plan to do this again in a more risky area.
