I'm Alexander, most people call me Alex. I've been married to Elizabeth, Liz, for ten years. No kids. We have a wonderful sex life together, though I freely admit, I have cheated a few times, usually when away from home. Liz also occasionally has to stay away from home and I would be surprised if she didn't do the same, she is a very attractive woman and enjoys sex as much as I do. I have become obsessed with the idea. Not because I'm jealous, although I am a bit, but because the idea of her being fucked by strangers is a huge turn on. I would love to watch. I use the idea as foreplay, descibing scenarios where she gets fucked silly, often by several men, while I am a spectator. The sex that follows is always fantastic. While browsing one evening when Liz was away, I came across a doggers website that gave locations. There was a site a few miles away. I decided to take a look. I expected to be disapointed and I was. There were about six cars in the car park, some misted up, but no watchers and I wasn't going to be the first. I went back again the next night to a very different scene. About six men were grouped around a big SUV with its interior light on. I went to have a look. The widows were closed apart from at the top, open for ventilation. The back seats were folded down forming a fucking platform where a woman was riding her partner cowgirl style. Her blouse was open, her tits on display. Her skirt was around her waist. Craning my neck to see, I was just able to see his cock pumping into her. As I watched, he pulled out and shot his spunk over her arse. Show over. Or so thought. The performers opened the rear doors, the man got out and 'adjusted his clothing', the woman, still with her tits on view, swung her legs out. One of the men stepped forward and offered his erect cock to her mouth. She sucked him off, letting him come in her mouth and swallowing his spunk. Another man took his place. She sucked them all, some came in her mouth, some pulled out to finish by wanking onto her tits, which she held up for them to shoot on. When it came to my turn, I declined. I'm not sure why, I just bottled it at the last moment. The meeting dispersed. I had witnessed my first dogging. In bed alone later, I wanked myself to two ejaculations reliving it. Except that the woman in the car was Liz. Could I persuade her to try? The night she came back, I set the scene for her; "We're in the car on the way home after a night out, both feeling horny. I pull into a secluded car park, we kiss. I feel your tits through your dress, eventually lifting them out of your dress to suck your nipples, you fish out my erect cock, bend down and suck it. But what we really need is to fuck. Just like before we were married, we get into the back seat, you sit astride me and feed my cock into your cunt. Only then do we realise that someone is watching. But we are too far gone, we continue to fuck. He walks over, takes out his cock and wanks as he watches. He is joined by another man, then another. Soon there are six watchers, all wanking. As I come inside you, they also start to come, splashing their spunk on the car. You have just made seven men ejaculate." As I spoke, I fingered her cunt and rubbed her clit. She came like an express train on the word "ejaculate", I mounted her and fucked her to another orgasm before unloading my pent up load deep into her clasping cunt. The next night, as we started our foreplay, I said quietly; "We could make it real if you wanted to." "Make what real?" "The sex in the car thing. With people watching. Before we were married we stopped if we were interrupted, suppose we didn't stop? Suppose the watchers just watched and wanked? Imagine having the power to make all those men come just by watching?" She did not reply, but once again, our fucking was exceptional. Two days later, she said; "Did you have somewhere in mind, somewhere where people fuck for the entertainment of others?" She was hooked. Together, we looked at that website again. She said that she was excited by the idea, but wanted to see what happened for herself first. Our recce trip was better than either of my solo attempts, not only did we see the same woman that I saw on my second visit, devour the offerings from several cocks, but watched as another woman who arrived later, fucked by those able to go again. The next day, Liz said that she was up for it, but she would just show herself, not fuck, and the doors were to be locked and the windows wound up. We didn't not have an SUV, just a medium sized family car. She would sit alone in the back, I would drive in, turn on the interior light and wait for things to happen. Only then would she decide whether to go through with it. But I knew her well enough that, once the seed was sown, she could not resist it. She made me wait downstairs while she readied herself. She came down wearing a belted raincoat, fastened up to her neck. But not because it was raining. She would not show me what was underneath. We arrived at the car park at dusk, wanting to be ths first. She climbed into the back. When other cars started to arrive, she told me to turn on the interior lights and removed the coat. She wore lingerie that I had not seen before, lingerie that was designed with sex very much in mind. A black basque supporting black, deep welt stockings. No knickers. She kept the coat near to her, ready for a quick cover up. The spectators began to gather, this time there were women too. Liz eased her fine tits out of the basque and began to fondle them, lifting each so that she could suck the nipples. Cocks began to appear on both sides of the car. Liz spread her legs wide and began to finger her cunt. I was in the driving seat, twisted round so that I could watch. I could not resist joining the wankers, I fished out my cock and stroked it gently. Liz was close, one hand moving from tit to tit while the fingers of the other worked her clit. She came noisily. I jerked harder and shot my spunk onto the dashboard as the wanking men's contributions spattered the side windows. "Go," yelled Liz. "Go now, take me home." I tucked away my cock and we made our exit. She was, as they say, gagging for it by the time we got home and despite me wasting an entire cock full by fucking the dashboard, I was able to give her what she needed. We haven't been back, but now that her curiosity has been ignited, I fully expect to do so. I cleaned my own cum off the dashboard, but I didnt fancy washing other men's spunk off the doors and windows, I visited a carwash to get rid of that. An unexpected consequence.
