This happened on a weekend a few months ago, my wife went to Oxford for a shopping trip with her sister. They had left early in the morning and they were going to stay on and have a meal after. It meant that I had the whole day to myself, before lunch I went online and spent an hour or so watching my favourite porn site and I finished off by going upstairs to have a leisurely wank.

After lunch I was still feeling horny and was undecided how to fill the rest of my free time, I had the choice of going to a massage parlour or visiting the notorious lay-by about fifteen miles from my home. It had been a few years since I was last there and I was curious to see it it still lived up to its seedy reputation, so the lay-by won.

When I drove in half an hour later I saw that there were two cars and a small white van parked in a line, I parked behind them as I sat watching for a while. Nothing seemed to be happening so I put my jacket on and went for a walk passing close to the other vehicles so I could look into each one.The driver of the first car car was looking at his phone while the driver of the second appeared to be reading a newspaper but by the movements underneath I suspected that he was actually wanking his prick.

As I was passing the white van I saw that the driver made no effort to cover his semi erect prick which was poking out off his trousers. I carried on walking to the end of the lay-by then turned and retraced my steps. When I reached the van I hesitated for a few seconds and the driver reached across and opened the door which I took as an invitation to get inside.

He asked my name and said his name was Tony and was married. All the time we were talking he continued to stroke his impressive prick, it was thick with a large purple helmet. He told me that I could touch it if I wanted to and said it was quite safe because he could see in the wing mirrors if there was anybody getting close. I told him that he had nice looking cock and wrapped my hand around it and started wanking him. It was very dry so I licked the palm of my hand and pushed it down the shaft, telling him to imagine that he was slipping it into a tight slippery cunt. Tony groaned, pulled his trousers down further and pulled his large balls out. I wet my hand again and continued wanking him while I cupped his balls in my other hand. As I looked at his cock I knew that I wanted to take it in my mouth. I asked him if his wife ever sucked his cock , he laughed and said that she only occasionally sucked it for a few seconds as a special treat before they fucked.

I lowered my head down to his lap and sucked the large head Ito my mouth and began to move it up and down the thick shaft. I stopped sucking and told him to imagine that his wife had just told him that she was going to suck him until he came into her mouth and promised that she was going to swallow all his semen.

He held my head gently as I resumed sucking him, as I moved my mouth quicker I could feel his legs quivering and then a slight throbbing of his cock, he gasped and I suddenly felt and tasted my mouth filling with his thick semen. As promised when he finished I swallowed everything.

I sat upright in the seat and watched while Tony used a tissue to clean his cock. He asked me if I wanted him to do the same to me but I told him that I had wanked myself off a few hours earlier in the day and it would probably take him a considerable time to bring me off again. Tony thanked me and said he hoped we would meet again. I returned to my car and drove home .
