My wife and I had just watched a documentary about dogging. Now Trisha wasn't the most adventurous woman with regards to sex, and in out ten years of being married we had only ever fucked outdoors twice. Once on a golf course, I was definitely in the rough. We had found a clump of trees with a lot of other growth and was well hidden, although we could see and hear the golfers nearby. The other time was on a wind swept beach that was deserted and we were inside a beach tent type thing that covered most areas, and again we probably couldn't be seen. After the documentary my wife declared that it was a load of rubbish and things like that just don't happen. I think the fact that the doggers were wearing silly masks probably helped my wife's views. I tried hard to tell Trisha that there are dogging sites and that there are two not that far from us. She wouldn't have it. In the end I told her that I would prove it to her and take her to one, It was a nice day and was the sun was dropping, so I told Trisha to get in the car. She got in saying that it was a total waste of time. We arrived at the nearest site and sat in the carpark. There was only one other car and it was rocking and was pretty well steamed up. " It's just a couple courting," my wife declared. I didn't care what or who they were, it had my cock stiffening and I leaned over and started to kiss Trisha. "Not here," she said pushing me away, "We could be seen." I pointed out that was the general idea at a dogging site. In my wildest fantasies I could only imagine Trisha sucking someone else's cock. Her remarks made it pretty much clear that there was zero chance of that. I drove us to the other site which was a bigger site, but also more secluded. This one looked more promising as there was six cars in the first bit of the carpark. I pulled in and stopped. All those cars but not a single person in sight. Then another two cars pulled in. The one car immediately put it's interior lights on and two men in their late twenties were quickly out of the second car and at the window of the car with it's lights on.. It was Trisha that gasped and said, "He's got his cock out. She's sucking it." As I put my hand on Trisha's knee she was trembling as she was glued to the action at the cars window. I tried slipping my hand up Trisha's skirt and was quickly batted away. I tried to kiss her but was pushed away as she was glued to the action. I could see she was biting her lower lip. It was something that she did when she was either nervous or excited, as yet I wasn't sure which she was. The man in the car with the woman got out and disappeared down a well worn track, My thoughts were that he was going for a wee. It was very shortly after he disappeared that the woman got out the car and bent over the seat, and the man that was being sucked, raised her skirt and slipped his cock straight into the woman's pussy and started to bang away at her. She hadn't been wearing any panties and was obviously ready for this action. His mate got in the driver's seat. Then we see her head go down. "My god, hes fucking her and I think she's sucking his mates cock," Trisha gasped. I told her what did you expect them to do at a dogging site. I tried to run my hand up Trisha's leg again. This time there was no resistance and when I got to her panties they were soaked. As I touched her pussy through her panties, Trisha groaned and wriggled her arse so her pussy brushed against my fingers. I was now kissing her neck and nibbling her ear as she watched engrossed in the action. Then Trisha let out a long deep groan. With so little stimulation she had just come on my fingers and they weren't even in her pussy. A few moments later she cried, "look." The two men disengaged with the woman and swapped places. "She's fucking the other one." She wasn't wrong the second one was plowing the woman's pussy and the first one with his cock waving around walked around the car and got into the driver's seat. As I hooked my fingers into Trisha's panties and pulled them to one side, she lifted her arse a little and widened her legs to give me better access. She groaned again as I slipped two fingers easily into her soaked pussy. It was now that I noticed that the driver from that car was now stood beside our car watching my fingers pumping in and out of Trisha's pussy. Trisha was still so engrossed with the men fucking that woman that she hadn't noticed. Knowing that the man had a view of my wife's pussy as I fingered it had me as hard as a rock. Our car was now steaming up and I turned the ignition on to lower the windows. As they wound down Trisha looked at the window to see the man stood just a few feet from her looking at her pussy. It wasn't him watching that really took her attention. "Oh my god, he's wanking his cock," she squeaked. From my position I was unable to see his cock. Her eyes were now transfixed on the man next to her wanking. It was a few minutes that she watched the man before he took a step nearer. I could now see his cock and it was a fair sized cock and the head looked red and angry from his pumping. I was still fingering Trisha's pussy and suddenly she groaned again as the excitement in her washed over her again. Her mouth fell open and her eyes closed. I think the man took that as an invitation as he took the final step forward and slipped the head of his cock into Trisha's mouth. I see Trisha's eyes snap open and I think she was about to pull away, but she was too late and the man had a hand behind her head and pulled her head forward, sinking almost all of his cock into her mouth. With his hand steering Trisha's head I could no longer see her eyes, so I wasn't sure if she was enjoying it. I know Trisha often gives me good blow jobs, but it is not her favorite pastime. She would much rater have me fuck her. I could hear lots of slurping and sucking noises as the man fucked Trisha's mouth. His hand relaxed and then pulled right away. Trisha was now bobbing up and down the man's cock on her own. I could see that the man had thrown his head back and his eyes were shut. It was just seconds later Trisha was gagging. Then I see why as the man's cum started to escape the corner of her mouth and roll down her chin. This was definitely way beyond what I had expected, I had expected Trisha to insist I take her home when she saw the first sign of any action and now she was the action. The other two men had finished with the woman in the other car and were now stood by our car watching Trisha swallowing the guy's cum and my fingers in her pussy. Both of them had their cocks out but both were still limp after their action with the other woman.. She had disappeared completely from view while I had been watching Trisha. The man Trisha had just sucked off staggered a way a few feet and one of the men stepped forward asking, "Room for another one?" Trisha's hand went out and stroked the limp dick. It was a few minutes before it was hard and to my shock and horror she sucked it straight into her mouth. She knew that not too many minutes back this cock had been in another woman's pussy and yet here she was swallowing it as deep as she could. I was now excited, but even more upset, I had only hoped to spice up our own sex lives a little, not turn my wife into the local cumslut. By the time Trisha was swallowing this man's cum the third man was hard again and Trisha waved him forward and took his cock into her mouth. I needed some air and got out the car. The man who's wife or girlfriend had fucked these two was still stood there watching. "She's good your missus," he stated. I told him she was and asked where his had gone. "Oh she'll be down the track over there. In the clearing there's two other women getting a good seeing to and Lorna will be helping them out with all the men," I repeated all the men and he said yes probably about ten of them. It was now that the third mam came in Trisha's mouth and she was again trying to swallow all she could. Then as she wiped her chin with a tissue all three men thanked her and told her they hoped to see her again. I was back in the drivers seat and swiftly down the road on the way home. I was so shell shocked by what had happened that I never said a word on the way home. Once in doors, Trisha was all over me ripping at my clothes. What had I done I had turned her into a wild beast and she had me on the lounge floor on my back and she was astride my cock fucking me. She was kissing me. Kissing me with the lips that had just sucked off three total strangers. I wasn't enjoying this. A bit of spice is one thing, but this was way beyond that. After I had come and she had finished with me she declared that next time she wanted to see what went on down the track, as if she didn't already know. I tried to protest, but she stood her ground and told me, "If you don't like it don't come next time, but there will be a next time. That was over six years ago. I still don't like it that much, but mainly in the summer Trisha will go and suck and even fuck total strangers. I have on occasions fucked a couple of the women that go there, but again it isn't or wasn't what I wanted. The worse night for me was when there were eight men and she sucked and fucked them until an hour and a half later another woman came and took over from Trisha. I've heard it before, beware of what you wish for. If it could turn my wife into a sex starved cumslut that she now is what hope would you have with your wife, and there's no going back.
