Olga my wife is a dirty slut. The first time I set eyes on her he was on a coffee table on her back sucking two different cocks whilst a third was slamming in and out of her fanny. It was meant to be a swapping party that developed into an orgy and then to a gang bang and Olga was bang in the center of it. My girlfriend, at the time, was also on her back on the sofa taking some new cock. I had just connected with a pretty redhead and was on my way to any spare bedroom for my share of pussy. Later having relieved myself deep in the pretty redhead, I returned to the lounge on my way to the kitchen for some more drink. Olga was still on the coffee table, now on her front, taking a cock in her mouth and another in her fanny. They were not the same men as she had been with before. My girlfriend was nowhere to be seen. As I re-entered the lounge from the kitchen, now with new drink in hand. The man fucking Olga's face had cum all over her face and in her hair and the man fucking her was grunting as he pumped his cum into her fanny. Then it was the first time I had seen Olga without either a cock in her mouth or her fanny. "Give us a glug," she asked me, "I'm dying for a drink." I handed her my drink and told her the amount of cum she had drunk I was surprised she was thirsty. She responded that fucking always made her thirsty. After drinking most of my drink she asked if I wanted some as she looked down at her well fucked gaping fanny. I was semi hard and told her I would as I maneuvered into position and slipped effortlessly into a loose slippery fanny. I was beginning to think this might not have been the best decision I had ever made as she was so loose. Then as my balls touched her fanny she tightened her muscles and she had my cock in a vice like grip. She sure had some muscle control as I started to fuck in and out. Having cum in the redhead not so long back I lasted quite a while as Olga slapped my arse to encourage me to fuck her deeper and harder. She never came even when I pumped my cum into her to join with what was already in her. Olga thanked me as I pulled out. There was another man stood watching and as I stepped away he stepped in and took my place in Olga's slimy wet fanny. I wandered back to the kitchen for another drink plus another for Olga when she had finished with her latest man. By now quite a few of the guests had left the party either with their partners or their new found partners. I sat on the sofa and Olga joined me when the man grunting on top of her cam and then staggered away. I handed her a drink and she gulped most of it down. It was now when I found out her name and that she was half Swedish. I joke that was perhaps why she was suck a slut. She joked that her heritage had little to do with it, she just loved cock. The hosts wife appeared on her way to the kitchen for drinks and stopped and told me that my girlfriend had left with one of the other men at the party. I was a bit surprised as we had always arrived and left together when swinging. Olga joked that I was all hers then. I was pretty tired and told both Olga and the Hosts wife that I would be going home shortly. Olga said she would be going with me. I asked about her partner and she informed me that she didn't have one or need one. Being such a free spirit she said she was always invited to the best parties. Shortly after finding my clothes and dressing I met Olga in the hallway. She had also dressed. "Lead on," she told me as I opened the door to leave. Twenty minutes later we were in my bed and Olga was sucking better than any vacuum cleaner trying to raise my cock for another fucking. It took a while until I was hard enough. I asked Olga what her favorite position was. She never spoke but just climbed up me as I lay on my back and straddled me. Again I slipped easily into her wet pussy. Again her muscles clamped her pussy onto my cock and then she rode me to another fabulous orgasm as I pumped more cum into her pussy. Shortly afterwards I fell asleep. I awoke to find the bed empty and a large stain where all the mixture of cum had leaked from Olga and stained my sheets. I found Olga in my shower and joined her and as we lathered each other she stroked my cock into life. It was my first fuck in a shower. It was good, but cramped and uncomfortable. Afterwards before Olga dressed and left she gave me the address of another party that coming Friday and she would be there and if I attended I could be her plus one. My girlfriend turned up two days later telling me how good Greg was and that she had been with him since the party. I knew I had lost her. In fact she broke Greg's family up and ended up living with him. At the next party I found Olga She was a little more reserved as she only fucked two of the men before we left for my house. We became a couple and attended many parties and I found that I enjoyed watching Olga almost as much as I enjoyed fucking her. About a year later I asked her to marry me. Her only concern was that I would want exclusivity with her. I assured her that she could continue to see other people. We married six months later. We are now in our fifties and Olga still loves to party. I prefer to watch and take my turn when we get home. Olga has never had a gang bang since and will only take on one or two men at each party now. That was until this damn virus hit.
