It was a really hot day and I had been working in Oxford and watching all the young lady’s walking around in their short skirts and tight shorts was getting me very horny , so on my way home I decided to stop off in a lay-by for a quick wank, I pulled up unzipped my trousers and took my cock in hand , I closed my eyes while thinking about all the Horny girls I had been watching in Oxford, I had been wanking for about 15 minutes and all of a sudden there was a tap on my window and there was an old bloke about 70 - 75 standing by my van , I still had my cock in hand , he was wanting directions to the next town but wasn’t sure if he had missed his turning , I gave him the directions while still holding my cock , and he looked at what I was doing and said I’m so sorry for disturbing you and off he went back to his car. It ended up being the best wank I had ever had knowing I had been caught , I just wish I had asked him for a hand.
