Mandy had been a slut ever since I had known her. I met her whilst in University and she was working her way through not only the students, but also the masters. I couldn't complain, I had my turns with her and she was definitely one good fuck. Not only that but she was also the best cock sucker I have ever met. Then I lost contact for a while. It was only when I moved back nearer my parents home and met up again with old school mates. I discovered that Mandy had married one of my old mates. I asked one of my other old mates what he knew about her and it appeared that nobody knew of her former cock sucking and fucking slut days. I got the chance to speak to her a few weeks later on her own. She pleaded for me not to let on about her and my pasts. I told her I would think about it as Mark had married her not knowing her past. A few days later she turned up at my house and again pleaded for me to keep quiet. Then she offered to make it worthwhile if I kept quiet. I must have looked confused, because she dropped to her knees and freed my cock from my trousers and pants. Then her lips covered in red lipstick were around the head and sliding it slowly into her mouth and down her throat. She still had it and she was making the most of it. I decided that I needed more for my silence and lifted her up and turned her around and bent her over the table. I pulled her skirt up and her panties down. Then taking quick aim I was in and deep inside her well used pussy. Mandy was thrusting her pussy back to meet my cock as I plowed into her. We didn't last long before we were both building up towards what proved to be a great orgasm. I filled her pussy with my load. Then she used that bathroom to clean herself up and redress herself. I had put my cock away when she returned. "So you'll keep my past and today to yourself?" she asked. I told her I would. Then she gave me a lingering kiss and left. At the time I thought that was it, so I was totally surprised when she was at my door again three days later. I let her in and asked what she was back for. She informed me that she missed her old ways and needed some more cock. I asked her about Mark and she told me that he thought she was out with one of her mates and didn't expect her home until about eleven p.m. We were soon in my bed as I licked her pussy as she sucked my cock and played with my balls. She shook from head to toe when I sucked her clit into my mouth and licked it all over. Then her orgasm washed over her and as she came down from her orgasm I climbed up her body and slipped my cock deep into her pussy. She was off again on another orgasm. I fucked her for a good fifteen minutes before I reached my own release and filled her pussy. We fucked again later when I had recovered and she helped me to another erection. This time in what I knew used to be her favorite position. (Doggy) We both came and then as we lay relaxing I went and poured us some wine as Mark expected that she would be at a pub. After that she would come to me once a week for a good shagging. Then I heard rumors that she was having an affair from another mate. I felt guilt and asked who with. I was relieved when he said that the rumor says it was with Rodney. The following week when Mandy rocked up at my door I asked her about the rumor. She didn't deny it and told me that our first session all those weeks back had triggered her longing for the old days and she gave in to her longings and ended up sucking and fucking Rodney. Then she confessed further that she had also slept with Bill, Graham and Tony. We had our weekly fucks and a drink or two and she was on her way home. I was later that week that I heard that Mark had come home early and caught her with Trevor. She claimed it was a once off. Well it might have been with Trevor, but she was making her way through all Mark's mates. After a lot of pleading Mark forgave her. She still rocked up at mine again on Wednesday night regardless of having been caught by Mark. I fucked her silly knowing that she would eventually get caught out again and my regular fucks would come to an end. Well she did get caught again about a month later. Mark caught her with Hermon and Jeff getting double teamed. He walked out on her. Since then she seems to have increased her stable of men. My Wednesday nights were still ongoing until Covid. It just goes to show that once a slut always a slut. She is still the best cock sucker and fuck that I've ever known.
