To say my wife is a dirty filth slut would be a gross understatement. I got home from work and walked in the front door. I instantly knew what she was up to from the grunts and groans. I entered the living room to find her sucking a large cock of a man sat in my chair and another man behind her slamming his cock in her fanny. "You'll have to wait your turn mate," another man sat on the sofa, slowly wanking his cock, told me and a forty man with a well fucked looking cock just grinned in my direction. Then there was the week before when we went to a swingers party the other side of the county. Over two hours, I had put myself about with three different women, and was now totally bushed. I made my way to the kitchen to get a drink and heard two women complaining about a third woman. "That dirty pig has hogged all the cock," one said. "I know, she grabbed my husband, and he never knew what hit him and then she was hunting for more cock. In the kitchen there were four men and she dragged all four of them into a bedroom and one by one they all came out looking totally fucked. Then she grabbed two more and all I've managed was one cock all evening," the other woman said. As soon as they saw me the first one said," you up for a fuck?" I looked at my wilted cock at the same time as she did. "I see that filth slut has got to you to," she proclaimed. I knew straight away that they were talking about Avril. I just nodded. "Well I'm going to find Lance and were going home," the first one complained. The other one said she would do the same. Taking a swig of the drink I had just poured, I followed the two women through the lounge. There was three women in various sexual acts with three men. Then there was a couple on the stairs. That looked quite adventurous and possibly dangerous. Then we went up the stairs and looked in the first bedroom. The man there was on his back lapping at one girls fanny whilst another rode his cock. The second bedroom had two couples taking turns with two women. One was the woman that I had left a few minutes back. Then we got to the third bedroom. Guess what? It was Avril. She was sat on one mans cock and a second man had his cock up her arse from behind whilst a third man was face fucking her and to compound matters she was trying to wank a fourth cock. "Lance get off that slut, were going home," she barked at her husband. He was quick to take his cock out of Avril's arse which caused Avril to moan with disappointment and the loss. The woman dragged him out of the room. The other woman spotted her husband. He was the one underneath Avril. "Get that slut off you, your going home," the second woman snapped. He pushed Avril off of himself and he scurried away looking for his clothes. "If I was you I would keep away from that filthy slut," she told the three of us males still in the room with Avril. Shortly afterwards the couple hosting the party asked us to leave. That brings me up to about two years ago. Avril was still fucking any man that stood still long enough for her to get his trousers off. I was living with a permanently sore cock. I needed some respite. Then I heard about a local dogging site. I told Avril that I was going to take her out on Saturday evening. It had been a hot day, so when I suggested her short skirt and a tee shirt that barely covered her tits and then dangled just below them, she wasn't to surprised. She asked where we were going and I told her she would just have to wait and see. It was getting towards nine p.m. I drove the three miles to the carpark of the forest trail start and stopped at the far end of the carpark. There were three other cars in the carpark. "What the hell have you brought me here for," she asked. I told her to wait and see. I leaned across and put my hand up her skirt and started playing with her pussy. "Oh goody your going to fuck me," she claimed. I told her not me and flashed my lights and put the interior light on. In just seconds the car had three men peering into the windows. It was just a few seconds before Avril saw that they all had their cocks out and were playing with themselves. I wound the windows down and a cock was thrust through Avril's window and into her face. Being the slut she was she sucked it into her mouth. I bet even a Dyson couldn't suck that much. The man soon had her tits exposed and was playing with them as Avril sucked his cock. There was complaints from the other men that they weren't getting any. I got out the car and walked around to Avril's side and pushing the man out the way and pulled Avril out the car, not that she needed much pulling. "Enjoy," I told the men as they escorted her to a picnic table and spread her on it. The first man had his cock back in her mouth, the second was licking her fanny and Avril was wanking the third. Shortly the man sucking her fanny stood and dropped his trousers and pants and slammed his hard cock deep in Avril's fanny. As the second man came in her mouth two more men arrived and their cocks were soon swinging in the breeze. I could see that Avril was being well taken care of, so I told her I would see her later and went to my car and drove home. I left her there for a little over three hours. When I got back to her she was sucking a man's cock as he sat in his seat in his car. She finished him and swallowed his load. "See you again next week then," he said as he tucked his deflated cock back into his pants and zipped it in. Avril just giggled and walked away and back to my car. I got in the drivers seat and Avril came to my side of the car. "So do you want a blowjob sir," she asked me, giggling. I told her that I thought she would have had enough cock for one day. She nodded in agreement and pushed my door shut and went and got in the passenger seat. I asked was she ok. "OK," she said, "I'm more than ok. I don't think I have ever had so much cock. Lucky me,"she said as she lent over to me and give me a wet sloppy kiss. As we broke the kiss I just remembered what had been in her moth just minutes back. Then I started the car to drive us home. "What was that about see you next week," I asked. She quickly answered telling me that she told all of them she would see them the following week. She went on to tell me that during the evening she had sucked nine cocks and fuck fourteen she thought but she had lost count. She did complain that she was a little sore and needed a good bath. Once home I poured her a nice hot bath with lots of bubbles and as she lay in the water I got her a nice large glass of red wine. "What a perfect evening," she told me. From then on whenever she got too much for me and my cock, I would take her to the dogging site and leave her until she called me to go and get her. Many of you might say what a nice problem to have, a woman that is so demanding, but I assure you that you would not say that if it was your wife. I'll be glad when this Covid is all over as it is causing me a sore cock.
