I'm pretty sure it is genetic and runs in families. Both my dad and grandfather cheated on their wives, and my grandfather now in assisted living has three of the residents on the go as well as fucking the cleaner that helps the less infirm at the unit. I to am that way inclined and the start of my account was when my steady girlfriend caught me in bed with her sister. I made a conscious decision that what I needed was an open relationship. A mate recommended Mandy a few roads away. Even for me she was to way out there. When I got to see her she had a line of seven men waiting for her favors. Then there was all the tats and the rings. She must have weighed half as much again with all the metalwork embedded in her. I walked away. I went back to the contact mags I had used before to troll for some fun loving women. I contacted a few and decided to put an add of my own in the mag searching for a woman that wanted an open relationship. It was about a week and I had answers from two of the three that I had contacted. Both married and both going behind their husbands backs. It was another week before I had two replies from my own add. One was married and the other single. The married one was again going behind her husbands back and wanted regular fun as she put it. The single woman Sarah said she thought she was a nymphomaniac as she spent over twenty minutes of every waking hour thinking about sex. That definitely sounded like a nymphomaniac to me. From her photograph she looked presentable and even a bit pretty. I loved the look of her freckled face it made her look quite sexy to me. She sounded intriguing and I rang the number she had sent in her letter. We talked for some while and I soon discovered that she lived quite some way away. I suggested that she traveled to me and I collect her at the coach station and she stay for a long weekend to see how we got along. Sarah took me up on my offer saying that she had run out of fresh cocks where she lived. She arrived just after lunch on the Friday afternoon and I collected her as I had said and took her to my house. Sarah was even prettier than her pictures. I showed her to my bedroom and said if she preferred there was a spare bed in the next room. She laughed and said my bed would do just fine at which time she stripped and sprang at me dragging me into bed. I was soon licking her juicy pussy that she told me was permanently damp if not wet. Sarah wasn't contented to just lie there take a licking she soon turned around and had my cock in her mouth. Then when she was ready she mounted me and rode me to a long hard climax. We made love several more times, and evening still hadn't arrived. I knew I was in trouble, there was no way that I was going to be able to satisfy Sarah as she showed little sign of slowing up. I suggested that we went out for something to eat, which fortunately Sarah agreed with, and I was relieved as I thought I was going to be the main course. During the meal Sarah flirted with the waiter. Then she disappeared to the ladies for quite some time. I later discovered that she shagged the waiter in the loos. Later we went to a club and she danced and flirted with several men quite outrageously and at closing time she brought two of them back to my house with her. They thought it was their birthdays and Christmas's all rolled into one. It was three in the morning when she finished with them and kicked them out and we finally got some sleep. I awoke to a mouth on my cock and hands rolling my balls around. We were fucking again in just a few minutes. Sarah wasn't into much, if any foreplay, she was a more stick it in and get on with it type. Afterwards we lay talking and she told me that about twice a year she got the hots as she called it and it seemed that she just had to have cocks and many of them. Lucky if you can call it that, she was in the middle of one of these sessions. I asked how long it lasted and she said anything from a few days to two weeks and then things would settle down again although she would still have a higher than normal sex drive. She informed me that she was on day seven this time around. By lunchtime I was well and truly exhausted. I knew of a party happening that night and suggested we go to it. I knew there would be several single men there as well as lots of couples. I could see her eyes widen at that news. Now all I needed was to get through the day. I took Sarah into town as it was somewhere she had never been. She loved the shops and we went into one of the large clothes shops and she wanted to try on a dress. There was a man waiting for his wife or girlfriend while she was in the changing area. I wandered off looking for some new jeans. When I returned the man was gone and a woman was looking for him to pay for her clothes. The woman eventually wandered off around the store. Then Sarah and the man appeared from the changing area. Sarah looked happy and the man quite disheveled and worried. I don't think the poor man knew what hit him. We made it to the party without any further incidents, but once there she was like a ferret down a rabbit hole searching for prey. It wasn't long before she had her first kill and it wasn't one of the single men. The poor wife was wandering around wondering where her husband had disappeared to. He reappeared some time later much to an annoyed wife having been abandoned. His excuse was he needed the toilet as he had an upset. After him she had a steady stream of men beating their way to the bedroom where Sarah had camped out. I met up with Mindy one of my old conquests. She wanted to have some fun, but I had to tell her that I was all fucked out, but would like to take her up on it another time. At the end of the evening Sarah brought one man back with us to my house and to my surprise she had prized him away from his wife. He lasted two hours before Sarah kicked him out to go home to his wife with his tail between his legs, or should I say limp cock. Next morning Sarah was like a different woman. She waited for me to make a move on her and we lay kissing for some while. She made no move to jump me as she had over the last two days. In fact when we got around to making love it was a nice slow sexual loving screw. Afterwards she told me that her session had passed, not to say that she was wasn't still wanting sex, but now she controlled it and not the other way around. We had a wonderful day and although we went out to a local beauty spot she didn't once proposition any men. It was to be our final night together unless we wanted to see more of each other and we went out for a lovely meal and then returned home and again made slow passionate love together. Laying in the after glow we talked and I told her that I wanted to see her again, but wasn't sure how I could cope with her sessions. Her answer was to just let her do her thing if and when it happens. Monday morning I put Sarah back on the coach for home before going to work. At work my work buddy asked about my weekend and I told him about Sarah. He joked that he would have come across and helped out had he known I couldn't cope. Sarah came for two more extended weekends. Although she did sleep with one or two men those weekends it wasn't the manic sexual frenzy that we had the first weekend. In between times I had hooked up a couple of times with Mindy and another woman. The other woman was at a party that turned into an orgy. It turned out that the host of the party often had sex parties and I was given an invite to them via the woman that I had hooked up with. Then Sarah arrived for the fourth stay and I could see in her eyes the look when I met her off the coach. She was ready to devour any man that was available. I remembered back to what my work buddy had joked and after I untangled myself from Sarah for the second time I gave him a call. He too was exhausted in a fairly short time. He had another mate that he called on and he also was soon pressed into service. Eventually just after one in the morning Sarah and I settled down to sleep. Next morning I was again jumped on and exhausted even before ten o'clock. At lunch time I took Sarah to a nice pub for lunch. The only snacking she wanted was of a different kind and soon had two men in the ladies with her. When they emerged the men looked the worse for wear, but Sarah still had that wanton look on her pretty face. How I got through the rest of the day I will never know, but I did and was sure glad we had the party to go to. In minutes of getting to the party she was off with several men in one of the bedrooms. The woman I had met before was also busy so I chatted up a woman called Rhona. Her husband was off somewhere with someone else and she was left to fend for herself. She said it wasn't unusual to find herself left alone by her husband. We kissed and cuddled and generally sat chatting. She asked about my wife as she had seen me arrive with Sarah. I explained that Sarah was a girlfriend that had unusually high needs. I ended up in a bed with Rhona, although we kissed and cuddled she wasn't ready to make love so we just lay cuddled together. Later we dressed and I found Sarah wandering around with some chap. She said she wanted to go home, so Sarah and the chap and myself and Rhona went to my house. Sarah was soon fucking the man in my spare room and I was again in bed with Rhona. This time we did make love and very nice it was to. It was about one in the morning when I hard Sarah at the front door with the chap and he left. Then she was climbing in bed with Rhona and I. She cuddled up to my back as I cuddled and held Rhona. Next morning I had two women sucking my cock and balls. After I had screwed a bit with both of them, Sarah pinned Rhona down and straddled her face and insisted that Rhona suck and lick her pussy. I later discovered that it was Rhona's first time with another woman, not that you would have guessed after a few minutes. They were in a sixty nine for a good forty minutes before they troubled me again. I was soon exhausted. Rhona rang her husband who was still at the house where the party was held and he came over with three other men. Was I pleased for the support. Rhona and I just cuddled in my bed whilst the four men took Sarah to the spare room. Just before midday Rhona and I got up for for some brunch. Sarah was still going at it with the men. A little after one the four men and Sarah eventually came down stairs. After drinks the men and Rhona all left. Sarah told me that her session was over for now. The rest of the weekend was fabulous and I regretted having to put Sarah back on the coach. Her next visit came quicker than I expected. On arrival she told me that she had come to get away from troubles at home. It transpired that she was caught fucking her landlord. The problem was that it was his wife that had caught them and she feared when she went back she would be slung out into the streets. I asked her to come and live with me. I rang work and took a few days off and drove to her flat and we emptied it with the landlords wife watching us. As we finished packing up the wife was calling Sarah all sorts of names and I had to step in and tell her to shut her trap if she knew what was good for her. Back home Sarah was soon in her stride with men coming and going, one or two a week. She soon found a new job and the men at home petered out. I could see it coming, the look in her eyes gave it away. She was on the hunt for cock, any cock, every cock. I rang Rhona and she and her husband came over. He like me was soon exhausted and Rhona was put to work much to Rhona's husbands surprise. He had never seen her with another woman. Fortunately he soon had friends from his swinger swapping group arriving. Between them all they kept Sarah happy all weekend and for the next few nights after work. From then on Sarah was the party when one of her sessions happened. We had a large group of men that would come and service Sarah until it subsided again. By the time we got to our mid fifties Sarah had far fewer sessions and they lasted shorter periods of time. She had a fairly regular lover that was still seeing her when he could escape his wife, and we still had a smaller group of men for when she did have a session. I was still seeing Rhona as and when, usually when her husband was off out shagging someone else's wife. Then a mate from work was caught playing away by his wife and kicked out. He and the sexy bit he was shagging moved in temporary until they could find somewhere else to live. Then the virus hit and we were in lockdown. We were in a bubble of four. Graham and Sarah were furlowed, whilst Jennifer and I were still working as we both had essential jobs. It wasn't long into lockdown when I came home to find Graham in bed with Sarah. Jennifer was a little upset at finding Graham already cheating on her, but it didn't take a lot to persuade her to join me in my bed. After that swaps happened quite frequently. Then Sarah went into one of her sessions and nowhere to go or help to appease it, Graham and I were exhausted trying to keep up with her and it wasn't long before Jennifer was pressed into service to help. It turned out that Jennifer had experience of pussy from her school days. Fortunately Sarah's session only lasted three days. Once things started to open up again and restrictions eased Jennifer and Graham found themselves a place of their own. Although I haven't seen Rhona or her husband during lockdown, we have kept in touch. My problem is going to be here again pretty soon, as Sarah must be due for another session. I only hope that I can get help from Graham and Jennifer as well as Rhona and friends when it happens.
