When I was married, we were driving past Branksome Chine late one evening and there was a full moon over the sea. Pat, my wife, said “There is a clifftop car park behind the library at the top of this hill. Pull into it and we can see the moon”. We stopped and got out to look at the moon and it was a great site as it rose over the water. It felt romantic as we cuddled up there and we started kissing. It didn’t take long to get horny and Pat said lets’ get back into the car. We got into the car and were soon kissing again. “Let’s get home“ I said, knowing I was on a promise. “No, lets play here, it’s perfectly safe” she replied. I couldn’t see anyone around and thought it might be fun, so I opened her top to get to her tits. She kicked off her shoes then raised herself off the seat and slid her skirt and tights off so I could finger her cunt and suck her engorged nipples. I then unzipped myself and my cock sprang out needing attention and soon P was sucking on my cock then I looked out the window and saw 3 men and a woman staring into the car, which was well lit by the full moon.. What I did not know at the time was that this was a dogging site. All the men had their cocks out, the woman had one cock in each hand and her tits were on full view. I found this a turn-on so smiled at them. I whispered to P, “Don’t stop but we have an audience” “Who”? She asked. I told her and it seemed to excite her that people were watching. Before I came she stopped sucking my cock and said, “let’s change places” and she laid back on the seat and I dived down to her very wet pussy. I thought I heard the window sliding down but was too busy to think about it until suddenly P came. After licking up her juices I looked up to see two hands on her tits – she had opened the electric window to let the watchers play with her tits. She smiled and said “I hope you don’t mind” “Not at all” I said, “you look very sexy like that”. I opened the car door and got out and found that there were now 5 men outside and still the one woman, who was bent forward with her hands on the bonnet and a cock thrusting into her from behind. Two men had their hands on P’s tits through the open window and the other 2 were watching the action. The woman being fucked had lovely big swinging tits, so I took the chance to have a play with them. She moved around and supported herself by holding me around the waist and took my cock into her mouth while still being fucked from behind. I had my back to the car and forgot all about P as the woman sucked my whole length into her mouth and throat. After a few minutes, I could hold back no longer and shot floods of cum, which she swallowed. It was only then that I realised what I had done and turned around wondering what P would say. I need not have worried. One of the men had got into the car and was licking her cunt while she sucked on a very big cock through the open window. The other two men were watching the action while playing with their cocks but seeing the other woman now had a free mouth one gave her his cock to suck. P stopped sucking and turned to me and said “You have had your fun, so I am having mine” “I would really like to try this big one in my pussy” “Go ahead” I said, as long as I can watch. She got out of the car and laid back over the bonnet, the man with the big cock slid it into her – it was big, but she took it easily. He fucked her for about 15 minutes before withdrawing and in that time, she came four times. He still had not come so P wanked him off over her tits. “Anyone else want to come on my tits” she said, and two others did so. By this time, the other woman had finished with her men and came over and said, “Hi Pat, It’s good to see you again”. This puzzled me, what did she mean? Anyway, nothing else was said and we left to drive home. On the way home I thought about the woman knowing Pat and when we got to bed, I asked her about it. “Did you enjoy yourself tonight” she said. I admitted that I had. “Did you like watching me being fucked by that big cock? She asked. I admitted that I had found it a turn-on. We talked about the evening, about me getting a blow job and her being fucked in front of me and all the while she was stroking my cock back into an erection then she dropped her bombshell “You know that I go out every 2nd Wednesday evening to the book club, well I don’t go to the book club, I go to that car park” “What? Why” I exploded but she kept hold of my cock as she told me that she needed extra sex and that was her way of getting it. I asked for more details and all the time she was stroking me as she told me that a previous boyfriend had got her into dogging and that she missed it after we got together. Eventually she couldn’t resist going back and found it as exciting as ever. She told me that she felt guilty cheating on me and had guessed that I might be Ok with it if I was involved as well. Then she took me into her mouth, and I was cumming within seconds. “I was right, wasn’t I?” she said, “You are really turned on about the thought of your wife being fucked by strangers, about their hands on her tits, their fingers and cocks in her cunt, about her having 4 or 5 men in one night” She was right, the vision had me still hard and she manoeuvred round and sank down on my cock. As she rose up and down on my erection she kept up her filthy talk, telling me about the different times that she had been there, about some of the men she had allowed into her body and about the woman that we had met earlier, who was called Sally and who loved to lick Pat’s pussy before and after it was fucked. Eventually I came yet again and then fell back exhausted. “Well” she said, “Do you divorce me, or do you let me continue because I know that I cannot give it up”. “We don’t divorce” I told her, “You can continue going but only if I can go with you and watch”. She gave me a big kiss and told me that she loved me then said, “Maybe we could go every Wednesday now I don’t need to pretend”.
