My wife Catherine and I were out for a day out and as the afternoon was slowly turning to evening we were making our way back home. I had decided to take the more pretty route rather than the motorway and larger "A" roads. It was Autumn so although it was getting a little cooler it was still ok. Then I started to get a wobble on one of the front wheels. At first it was minor and not wanting to worry Catherine I motored carefully on. Then it started to get worse and at that point I realized that I had to pull over. Fortunately there was a car park and I pulled in and stopped. I told Catherine what the problem was, expecting it to be a puncture. When I got out and looked, I was now worried as it wasn't a puncture and the front wheels were not quite in alignment. I called the AA and after some time and managed to tell them the GPS position we were at. The woman in the call center kept saying she wanted an address. I kept telling her that the road didn't seem to have a name and again told her the GPS location according to my cell phone APP. Eventually she told me that she had logged my call and someone would be on route. She also told us it would be an hour and a half before he arrived. As we sat there a car pulled into the car park. There was a man and woman in the front seats and shortly after he had stopped he had his tongue down the woman's throat. Catherine reminded me of when that would have been us. I told her that we were were never too old at forty years of age and turned to her and started to kiss her. We were soon disturbed by headlamps as another car entered the car park and parked next to the other car. It had two men in the car and they sat there for a few minutes and then the lights in the first car flashed as the internal light came on. The men in the second car got out and made there way to the woman's side of the car. We could see her lower her window as the men approached. Then we suddenly noticed that the men had their cocks out and the woman lent out the window to stroke and play with the two cocks. Catherine joked that perhaps I should get into the cue. Then suddenly the woman had her head out the window and she was sucking the first cock into her mouth. We were shocked. We had never heard of dogging at that point and were stunned to see the woman sucking the mans cock. We were no prudes and had a full sexual life of our own and had both had previous partners, but this was definitely something new to us. It was fairly obvious by the way he moved and then stepped away that he had just come in her mouth. I joked to Catherine that perhaps she should flash the lights and put the internal light on. the second man had stepped up and the woman had started to suck him and the driver of her car had stepped out the car. He joined the back of the cue. To my surprise Catherine again suggested that I join the cue. This time she seemed much more serious and I had to ask did she really mean it and she sad yes go. I got out and wandered over a little tentatively to the cue. The driver see me coming and suggested that I take his place and stepped aside. As I stood there and took my cock out another car pulled in. I nearly put my cock away and run. The driver said it's alright it's Reg and Melvin. I had no idea who they were, but the drivers words settled me. They sat in their car for a few minutes. The woman in my cue had just taken a second mouthful and as she swallowed and then asked was I there for a blow job or what. I stepped up and she sucked my cock into her mouth. It felt good and as I suspected I did not last very long. I watched as she swallowed my load. Then I was eased to one side as her driver stepped forward and she sucked his cock into her mouth. I watched her sucking as I put my cock away. Then as I turned to go back to my car I was stopped dead in my tracks. Imagine my shock to see Catherine with her window down and the interior lights on. She was sucking one of the new comers cock in her mouth. As I started again to walk to Catherine and my car I saw the man's hips jerking as he was obviously pumping his cum into my wife's mouth. I had no room to say anything as I had just had a blow job from the other woman. The man with Catherine pulled away and the second man took his place and Catherine was soon sucking his cock. I climbed into my car and sat shocked as I watch my normally demure wife sucking this strangers cock. He had his hand down her blouse squeezing her tits as he humped back at my wife's mouth as she bobbed up and down on his cock, He like me didn't last very long and I watched as Catherine accepted his load in her mouth and swallowed the lot. The two men at our car were soon back in their car and pulling out of the carpark as did the other two men. The man with the woman in his car had also come and after zipping up he wandered over to our car. "Haven't seen you here before," he told us. We told him that we hadn't been there before. He then told us that it was quiet tonight and that his wife normally expected and suck seven or eight cocks in an evening. I was about to tell him that we had never done this before when we see the AA van lights flashing and he turned into the carpark. I got out to meet him and the man rushed away to his car and soon left the carpark. The AA man looked at the underside of our car and declared that we had a tracking issue and would need a garage. I told him where we lived and what garage we used and he said it was in his area so he could drop the car at the garage and then drop us home. Then he busied himself in loading my car onto the bed of his pickup truck. Once loaded he had us jump into his cab and started the fifteen minute drive to our garage. As he drove along he said we had picked a funny place to break down. I asked why and explained that the problem started about two miles back before I had no option but to pull in. It was now that he told me that it was a dogging site of an evening. We looked confused. Then he explained it was a place that adults went to where they had sex with strangers. He said he had seen women sucking men off and men sucking men off and occasionally they would have normal and anal sex. I tried to look shocked. Catherine asked were there many of these dogging sites. He told her that there were at least four to his knowledge in our county and told us where the nearest one to our house was. Again I pretended to be shocked. It was almost half an hour before he dropped our car at the garage and then us home. As soon as the front door closed my wife was all over me. Ripping my trousers off me and pulling her skirt and panties off before she pushed me onto the sofa and straddled me. Having come once already I fucked Catherine for the longest time that I had fucked in years. Catherine came twice before I joined her and came in her. Afterwards we made it to our bed where we talked about what had happened. Catherine wanted to know if I had enjoyed my blow job. I told her I had and asked her had she enjoyed giving two strangers blow jobs. Catherine said she had, but the second one wanted her to get out the car and let him fuck her. She told me it was a step too far for her. Sucking cock and having her tits played with was far enough she declared. A few weeks later and an expensive repair on the car we made the first of three trips to our local dogging site. The first time we just sat in the car and watched. There were about a dozen cars arrive and leave at various times. Two women sucked most of the men and one got out and allowed two of the men fuck her. There were two men that also sucked cock and I told Catherine that it was something that I could never do. She told me that she wasn't sure that she could let a stranger fuck her. It was one thing to suck his cock and another to let him have her pussy. She told me that I could o and play if I liked, but decided to stay with Catherine. The next Time Catherine sucked three cocks and allowed them to take her tits out and one of them came on her tits, the other two came in her mouth. I again got a blow job and was offered a shag, but the woman insisted that a condom must be worn and I didn't have any, anyway I wasn't sure how Catherine would feel about me fucking someone else. Later in bed Catherine told me that she would have been happy for me to have a fuck, but wasn't sure that she was ready for that herself. Sucking cock was one thing but fucking was definitely another thing altogether. The last time I was offered a blow job by some bloke and told him no thanks. He asked me to give him one and again I politely told him no. Then I got a shag with the woman the had given me the blow job the previous time. This time I had condoms with me in case the opportunity arose and I fancied the woman. I watched Catherine suck two blokes and then the next one was lent into the car sucking Catherine's tits. What I couldn't see was that he had his fingers buried in Catherine's pussy. I was on my way back to my car when I heard Catherine groan loudly as she came. Then as she was recovering he helped her from the car and sunk a fairly large cock into her pussy as she lent on our bonnet. Not only had she let a stranger play with her pussy she had now let him fuck her and bareback at that. Fortunately he came across her arse and not in her. Then he walked away waving her panties around his finger. Catherine quickly got back in the car as other men were advancing on her. She sucked one more cock before we made our way home. In bed Catherine confessed that it was the most outrageous and yet exciting and scary thing she had ever done. I admitted that I had enjoyed fucking the woman and had seen another woman there that I wouldn't mind fucking. We ended the night with one of the best fucks we had since we met as teenagers. We agreed we had to go again. Then the dreaded virus hit. Catherine is gagging for the day to come where we can feel safe and go again. Catherine also wants to try the swinging scene when it's safe to do so. Me I love watching her and if I can get a blow job or some pussy for myself.
