This happened a while ago, masterbating out in the open is so much fun!!
I love masterbating outdoors, especially during the summertime when the nights are comfortably warm. I live down the road from a park which is shelterd by a number of tall trees and double storey houses, this park has been my favourite place for a late night outdoor masterbation session.
My night started out with me comming onto the computer (horny of course) and looking up stories on this site. After a few good stories I was getting worked up so I began to look at porn, getting increasingly hornier. This lasted an hour or two and by then my parents had gone to bed so I had the house to myself essentially. After about another hour of slowly edging I had to finish myself off. I went to the kitchen and went straight for my favourite anal toy at the time. A nice sized carrot, and some lube.
I went back to computer and stripped. I then slowly inserted the carrot up my ass letting out a small moan and a sigh. I needed something more so I put my clothes back on (with the carrot still in me) and quietly snuck out of the house and down to the park. I stopped around the middle of the open field and slowly took my clothes off again. I lay on my back with my ass slightly off the ground and pumped my ass for awhile gently teasing my cock. I then stood up and walked away from my clothes towards the other field. I then squatted down so I could slide up and down on my carrot which I did until I couldn't contain myself and I had an amazing orgasm.
I hope you enjoyed this story, I certainly enjoyed writing it.
