I lived in a neighborhood that was densely surrounded by thick woods. I used to like to go way down into the woods behind big bushes where no one could see and strip off my clothes and jerk off. I did this every once in a while for a couple years.
At the same time, there was a girl in my neighborhood who I knew through school and who I would flirt with a lot in class. Randomly one night in the middle of the summer, she messaged me and asked if I wanted to meet up with her and one of her friends (who I also knew from class) and just walk around outside. Of course, I agreed and went to go meet them down the street from my house. We decided we wanted to drink some beers, so we needed to find a hidden place off of the road. I already knew that my jerk off spot was hidden enough so I told them that I knew of a place we could walk to.
