I was under orders from my husband John to brighten up his brother Dave who had received a really bad time from his wife and then divorce. I had been doing as I was asked and in the process finding new horizons for myself, which had culminated in a public fuck by Dave and a bukkake (as I now know to be the correct description) from any that wanted in the dunes at Studland. We got home and cleaned up just before John returned from his golf tournament. After sitting out in the evening sun chatting about things in general, John asked Dave how he was feeling. Dave said that he was well cheered up with my help. John asked about Studland – what had we seen – plenty of naked women? Oh yes, replied Dave, gettiing up to all sorts of things. Of course, john wanted to know what, so Dave told him of some of the sights, including a full description of what I had done, without hinting that it was me he was talking about. John was impressed, and wished he’d been there to see it. I thought to myself that I was very glad he wasn’t. Soon it was dinner time, and the lads talked of golf, football, and their jobs while I prepared the food. We had a very relaxed evening. At John’s suggestion I changed into a little mini-dress I usually kept for when John and I were alone together, showing lots of tanned leg and, with a v-neck down to my navel, a good amount of my bra-less 36D boobs which could escape if I was careless. I’d left my pants off as well, but that was my idea. After dinner we sat around the box, John and I on the settee and Dave opposite, so it was easy for me to be ‘careless’ and flash Dave with tit or fanny. I noticed that John was hardly drinking, which gave me the clue that he was thinking of a session of baby-making when we went to bed. I was not too keen on the idea, because baby-making sex was almost mechanical as we were passionate to have a baby but nothing had happened in five years. In any case, I was a bit shattered and quite tender in the pussy area after all the sexual activity of the last forty-eight hours. Sure enough, at ten to eleven John said “time for bed – early start tomorrow.” Dave was staying overnight and we were all leaving in the morning, John and I for work, and Dave for his trip back to the 1-bedroom flat he called home. We said goodnight to Dave who wanted to watch the end of a film that was on TV and went upstairs, John to the bedroom, me to the bathroom, telling John on the way that I was going to give him a surprise. I had the small problem of explaining my bald pubes and cunt, but I had worked out a plan. In the bathroom I stripped off the dress and poured hot water into the sink. I Applied John’s shaving foam and ran the razor over my pubic area to remove the odd few bristles that I now know (having kept myself bald down there from that day) always seem to be missed, and to make sure everything, especially my labia, were completely smooth. I rinsed off lightly to allow the scent of the foam to linger and, donning a dressing gown, walked into our bedroom. John was sitting on the edge of the bed, naked. He had an erection so I guessed that he had been wanking in anticipation. I stood in front of him, legs apart, and told him that I had seen some women on the beach that had given me an idea for my surprise for him. As I said “I hope you like it” I slipped off the gown and exhibited my naked fanny. His look of surprise followed by a wicked grin and then him pulling me towards him whereupon he licked and kissed me all around the area said it all. I pushed him back and knelt astride his face so that he could get a good look and he licked me out. I was back on heat due to the shaving and sight of his erect cock so I quickly came. Then he lifted me off and put me on the bed face down. He slipped his prick into my cleft from behind so I lifted myself onto my knees with my head on the pillow, my big breasts hanging down for him to knead and play with while he slowly worked his cock in to his full seven inches and then almost out of me. As he had taken me in the morning I knew that we were in for a long session as he takes a long time to cum the second time around in one day - not that it had happened much recently. As he slowly pumped I drifted back to the doggy session in the dunes that afternoon. Only Dave had fucked me then, but I started to fantasise about what could have happened. I could see me from above, on my hands and knees being vigorously fucked from behind by a man with a huge cock – not Dave, but a stranger. There was a line of men behind him queuing up to take their turn. In front a stranger was wanking into my face, and there was another queue behind him. Some were standing by my sides wanking and cumming over me, and one was lying under me sucking and playing with my tits which were huge and swinging. As the man in my cunt came, another took his place. That one came and then another cock slipped into my cum-filled cunt. Again and again that was repeated. All the cocks were huge and gushed great wads of semen into me. Cum was pouring from my over-filled vagina onto the sand below me. The same was happening at to my face – large cocks emptying their balls into my mouth and over my face time after time. I was swallowing what seemed like gallons of spunk. Spunk was soaking my hair and running off my face. And I was cumming repeatedly in an almost continuous orgasm. It was an amazing sensation. Then the feeling of cock intensified as it started moving fast back and forth into me and became engorged as it ejaculate, but this time I heard John crying out “Yes. Oh, yes” and I came back to reality to feel his seed squirting right into the depths of me, and then we collapsed on the bed. It was hard to realise that I was in my own bed and I had only been fantasising, it had seemed so real. I seemed to still taste spunk and I had to run my tongue around my mouth , teeth and gums to make sure that there was no semen there. We were both soaked in sweat. “Christ” John said “you were hot tonight. If that’s what seeing sex in the dunes does to you, we’d better go there more often.” I just purred, and we turned on our sides facing each other, John with his head buried in my boobs, and went to sleep. The next morning Dave was going back home. I would have to make sure that he was happy when he left.....
