I had been going out with Sue for about a month. She had been out with several of my mates before we started seeing each other. One of my mates had declared that she was a good fuck and that he had taken her cherry. He was not wrong she did rattle well. It was Saturday evening and for one reason or another most of my mates were not around and Sue had been shipped off to her fathers for the weekend. The only mate around was Barry. He said he knew of a party we could crash. So we did. It was boring and most of the people there were old enough to be our olds. The booze was good though. We were just thinking of splitting when this woman came up to me and asked was I going out with Sue. I told her yes and she told me she was Sue's mother, and to go to Sue's house the following morning. There I am at Sue's house at ten o'clock the next morning. "Young man, I have come to a decision," she says, "I have heard of your reputation, and if you promise not to take Sues virginity, I will allow you to sleep with me." I did have a reputation for loving them and leaving them. There was a far higher ratio of girls to boys, or women to men, in the area and was in national statistics of being nearly 3 to 1. Plenty to go around, and here was a woman, without a husband offering herself to me if I didn't take her daughters virginity. Well that was impossible as Barry had taken her virginity, or so he claimed, and she was definitely no virgin. Brenda was a fairly good looking woman for an old. She had kept in fairly good shape and looked after herself. I pondered for just a moment. "Let me get this right," I said," so if I don't take Sue's virginity, you will let me sleep with you?" She replied yes. "Well now is as good a time as any.," I said as I moved in and stole a kiss. Brenda seemed a little shock at the suddenness of the situation. I grabbed a hand full of tits through her dress, she was much better blessed than Sue. She relaxed and as she started joining in, she was much better kisser than Sue. Brenda was now beginning to respond and a hand on the back of my head and the other around my waist. My other hand was on Brenda's arse, bigger than Sue's I noted. Then Brenda pushed me away. For a moment I thought It was some sort of rejection or trick, but no, she didn't want it in the lounge and dragged me along a corridor to her bedroom. ( a bungalow before you ask). In the bedroom I took her clothes off as she stood there fairly passively and then removed my own. I moved back in for another kiss and grabbed her now naked arse and pulled her tight to me. He warm body and especially her big tits felt good against my body. I could feel my cock growing as I began to enjoy this older woman's body on mine. She had now put her hand between us and was playing with my cock and balls. I removed my mouth from hers and lowered it to take advantage of her large breasts, much larger than Sue's. I sucked and chewed on her large brown nipples, Sue's were pink. Brenda let out several gasps and cupped my head to her breasts. After I had my fill of her tits I moved down stopping briefly at her navel and then down through the forest of brown hair to the thick swollen lips if her fanny, Sue's was fully shaved. It was a neat pussy and the lips were fully closed. A few runs from my tongue up and down the lips soon changed that, as the lips peeled open to expose her clit and her pink opening. Brenda was breathing hard as she stood letting an 18 year old man lick her private parts. I gave her a good tongue lashing and obviously hit the spot as her knees started to buckle and her hands were pushing down on my head to keep herself up. I picked her up and sprawled her on the bed. Her legs were wide open showing her glistening opening. I gave it a couple more licks before climbing up her body and taking aim with my cock. It slid home fully with only a small amount of resistance. Brenda groaned loudly as I penetrated her. Then she was thrusting up as I thrust down causing loud slapping sounds as our flesh met in the middle. We came together after only two to three minutes. "That was good," She informed me, "I haven't had sex in over four years and it was never that good," she said as we lay in the after glow of wild sex. I had my face between those tits again and the nipples were still rock hard. "The rumors were right," she said, "you really are a bad boy, but very good." We laughed at her observations. "Can I get some more of this," she asked playing with my cock. As soon as it gets hard I told her. If you suck it, the sooner it will be hard. Her answer more than indicated that she had never sucked cock and she thought it dirty. I nearly told her that her precious daughter Sue was good at cock sucking. In the end I pointed out that she was more than happy to have her fanny licked, so what is so different to sucking cock. Very very reluctantly I persuaded her to kiss the bell end of my cock. Then she protested a little to licking it saying it had just been in her pussy. A little more persuasion and she tried it, and I think, liked it. Then less resistance when I had her open wide and let it into her mouth. Then there was no stopping her once it was in her mouth, as she soon sucked me back to full size. This time I had her ride me so that I could play and suck her large pendulous tits as she bounced up and down. This time she came once on her own, and again as we both hit the high notes. After dressing she reminded me of our deal, I wasn't to take Sue's virginity. She asked when I was liable to want her again. With the job I had, I was often free most afternoons, I had made arrangements to see Sue Tuesday evening so told Brenda to be ready for me Tuesday afternoon. When I arrived she was dressed in only a skimpy sexy red nighty. We were soon in the throws of passion on her bed. Later after cleaning up Sue arrived home and I took her out for the evening and before I took her home gave her an extra hard fucking thinking about what I had done earlier with her mother. Over the next few months I fucked Brenda as much if, not more than Sue. This one evening I was out with Sue and she seemed a little quiet and wanted to talk, rather than just shag. She kept skirting around our relationship and then blurted out, "I saw you fucking my mother." I thought for a moment that I would be on the hunt for some fresh fanny. Then she asked what was going on as she had herd us talking about her. I explained the deal that I was not to take her virginity and her mother would screw me whenever I wanted. Sue laughed, "The dirty old cow, you can't take my virginity, Barry did." This confirmed Barry's boasts. "That serves her right, for trying to meddle in my sex life, that you are screwing her, "she said. I asked if she minded, and she said do what you want, so I took Sue's panties off and fucked her silly in the back of my car. This lasted with me screwing both Brenda and Sue for several more months. Sue eventually found someone else and moved on and although I screwed Brenda a few more times afterwards, she eventually called a halt to it, and I also moved on. It was good while it lasted.
