I’ve been with my girlfriend for nearly 5 years and we have a great sex life. We got together after our marriages broke up, and seemed to be making up for the lack of sex in our previous relationships respectively. Our adventures have gone from story telling, to trying new things with each other, to threesomes, foursomes and sex clubs. One thing we always fantasised about is dogging, but even though it seemed to excite us both I never once thought we’d do it until this month...... She was out on a social event at a local hotel on a Friday night. The venue was some 5 miles from our home and I’d offered to drive her there and pick her up. I was really encouraging her to let her hair down as she’d had a tough time with work and family and I wanted her to really enjoy the night with her friends. After dropping her off I sent her one or two messages telling her not to worry about how late she might be, and that I would collect her regardless. She seemed to be having a great time and the night was exactly what I wanted it to be for her. Shortly before midnight she asked if I would collect her and if we could give her friend a lift home. It was no trouble and I set off to collect them at the hotel. When I arrived I let them know I was in the car park and told them to come out when they were ready. Shortly after she arrived with her friend in tow and we started our journey to her mates house, which meant a short detour into a small village where there’s a well known dogging location. We’d once visited the location at night for a bit of a nose but nothing appeared to be happening on the previous occasion and we moved on quickly. When we dropped her friend off my girlfriend suggested we drive in the lanes that led to the spot in question - directly opposite the route to our home. She was definitely in a saucy mood, but I thought it would be most likely a repeat of the last occasion and we’d be there for ten minutes and get bored and leave. We chatted as I drove us to the spot which took us less than five minutes and continued to chat as I pulled into the car park. It was a mid winter night with no cloud and a full moon so it was bright enough to be able to see what was around us. There was at least two cars already there each with one Male in the car. We parked about six feet from the one car and turned off the engine, talking to each other like we’d just parked at the super market. She looked beautiful in her red velvet evening dress which showed her curvy figure off nicely, her tits visible with the deep v at the front. I complemented her on her looks and we started kissing. My hands wandered to her legs and her tits and she seemed to be getting horny very quickly which was probably a combination of the drink and the situation. To my surprise she stopped and hitched her dress up and took off her knicker and tights and dropped the dress from her shoulders so I could suck her tits - something which always leads to other things. The moonlight and the subtle light of the dash board illuminated her bare skin and neither of us seemed nervous of being watched as I sucked her nipples and played with her pussy which was nicely wetting up. As we played, another car entered the car park and it’s headlamps lit up our car and I knew that her tits would have been seen by the cars occupants as the car reversed directly opposite us, before stopping and turning its lights off. She seemed encouraged by the fact that someone would have seen her semi undressed and her breezing and moaning sped up as she undid my belt and jeans and reached into my boxers for my cock which was hard and wet by now. Pre-occupied with my cock she didn’t seem to notice the interior light go on in the car opposite as the driver exited the vehicle. He walked across the car park and close to our car before backing off and taking his phone out - he seemed to be sending a text - which seems most likely given the number of people who appeared rapidly afterwards. With his phone away he moved closer to the car. I felt I ought to make her aware that we were being watched and by the time that she seemed to register what I was saying, the guy was right next to the passenger window with his cock in his hand, slowly wanking himself off. This is the point where the evening become more erotic than I could have ever anticipated. My girlfriend can be very forthright which I love and often takes the initiative in terms new experiences, but I wouldn’t have guessed that she’d be as proactive as she was this night. “Shall I put the window down?” She asked. I started to tell her to do so if she wanted to but before I could finish my sentence she’d already tried the window switch but the window hadn’t dropped as the ignition was off. Frustrated, she quickly instructed me “drop the window!”. Turning on the ignition meant that the interior light came on briefly before the window descended and it allowed her to see his cock and him to see her in her semi naked glory. Her arm reached out for his cock and she started to wank him as his hands reached in for her tits. In less than ten seconds she decided to open the door for better access. What happened next was what seemed a semi real experience, highly erotic and one which makes that double jeopardy sense that I love when seeing my woman with another man. The polar opposite yet concurrent sensation of eroticism and jealousy. With the door now open the inside of the car was brightly lit allowing me to see my girlfriend half turned in her seat and her face pressed into the open jeans of a complete stranger who I could barely make out in the darkness outside of the car. She moaned loudly as she took cock into her mouth thrusting her head forwards and back at increased speed. She lifted her leg onto the dash board allowing the nameless man to play with her cunt. My attention was caught by two more cars arriving although I think to this day she has no idea that others cars arrived as she sucked fervently on the strangers cock. Not sure what to do with myself I put my finger into her ass. It was only then that I became aware that I was touching my own cock now weeping pre cum copiously and bringing me dangerously close to my own orgasm. In the darkness outside of the car I could make out several other people now within five feet of the passenger side of the car. Each was wanking as they watched the performance. One came closer and stood next to the wing mirror and reached in and began fingering her and telling her how sexy she was. She groaned loudly at the compliment and the feeling of being consumed by two strangers. This seemed to spur on the guy fucking her mouth and his hands reached into the car and pulled her head firmly towards him making her take his cock fully in her mouth, which she managed expertly. I was torn, the image of these large masculine hands on the back of my girlfriends head combined with her slopping, sucking noises and her moans of pleasure all conspired to arouse and confuse me. Totally involuntarily I felt my own sap rising and an unstoppable force in my balls as my spunk boiled up in my sack, crying for its release. Just at that moment her moans increased in intensity and I knew he was coming in her luscious mouth. His fingers curled into her hair as his load emptied on her tongue, he refused to release her head until each drop was swallowed. As he did I leant forward and shot my load at her exposed as cheek and pushed my finger deeper into her ass to punish her for being the slut I wanted her to be. The guy playing with her pussy now took position in front of her and without hesitation his cock was in her mouth. Probably due to his wanking, he was in her for moments before I heard her moan loudly and his groan of pleasure as another load flowed into her pretty mouth and down her throat. By now there was a small queue of men outside the car and to my best effort I recall seven in total being sucked off in next to no time. When the last guy came, he must of sensed that he’d be the last of the evening and thanked her for a great show and a brilliant sucking. Only then she turned around and I saw spunk all Over her chin and hands. Somehow she still looked beautiful with hair and makeup largely in place. I handed her some tissues which we keep in the car and drove away quickly in order not to attract more visitors. We plan to take a walk to the site during the day in order to get the thrill of that evening, although the real thrill is the fact that she seems to have developed a taste for this past time.
