We met a couple, Ray and Helen last summer on a cruise. Both wife's sunbathed topless around the ship's pool. Helen was gorgeous, 28, slender and a great pair of 38 inch tits. My wife Claire, 40, not a bad figure for her age with 36 inch tits. We promised to keep in touch as we only lived about 50 miles away from them. A couple of weeks after being at home, Ray rang and asked if we would like to come to a BBQ/party, from about 4pm. He told me that it was a special party that Helen had every couple of months with a few select friends and it would involve plenty of drink and that most people would eventually be naked for a Helen obession. Curiosity got the better of us and we accepted. We arrived at their house, in a very secluded area in Sussex at about 4pm. The nearest house was about half a mile away. There already a few people there., three single blokes and two couples plus Ray and Helen. They had all been there a couple of hours before us. Ray told us we had a lot of catching up to do in the drinks stakes and took us to his bar in the garden. After giving us a drink he introducing us to everyone, Claire and I separated and started to talk to the other guests. After about 30 minutes and a couple more drinks I noticed Claire and the couple she was talking to, start stripping and get into the hot tub. Claire looked very comfortable being naked in front of the complete strangers. The couple I was with carried on talking as if nothing was happening. I then saw Helen come out of the house, she was also completely naked, she looked great with a lovely tanned body and smooth pussy. She walked over to the three blokes and started talking to them. They then stripped off and picked up Helen and took her over to the hot tub and all five got in the tub. I wandered over to the bar, got a drink and went over to the hot tub to see if Claire was alright. I got to the tub and saw that Helen was wanking the two blokes either side of her. The third bloke was next to Claire and the woman from the couple in the tub was wanking her partner. The woman then lent over to Claire and whispered in her ear. Next she and Claire swapped places, the woman then stareted to wank the third bloke. I looked behind me and saw a naked Ray putting a couple of double inflatable mattresses on the patio. The other couple were now naked. Ray shouted over to me to join the rest of them and strip. I stripped and felt my prick start to rise seeing Helen's boobs going up and down in the water. I looked again and saw that Claire was wanking the bloke next to her. Helen then stood up and got out of the tub. The three blokes followed. The first and second had a six inch erections, the third had an eight inch erect prick. They all followed Helen to the mattresses and stood around her as she knelt down and proceeded to suck their pricks. The woman in the tub lent over to me and said " Enjoy the show, we act as fluffers for Helen, she has an enormous appetite for sex and will expect to be fucked for about the next hour by those three, while we watch the show. Then you, Tom, Bill and Ray can use and abuse her for the next hour. Us ladies will then have the three lads to ourslves". For the next hour Helen was fucked in a variety of positions and the blokes eventually came over her face. Then the four of us took over. I had never taken part in a gang bang/orgy and was amazed how my prick stayed hard and never came with the excitment. I looked over and saw Claire hanging over the side of the tub being fucked from behind by the bloke with the eight inch prick, she was moaning away. Ray then got Bill to lay on his back, while Helen straddled him and told me to fuck her arse, while she sucked Ray's and Tom's prick. God knows how many times Helen came. Tom then started to wank his prick and shot his spunk over her face. Ray came in her mouth. It was too much for me and I shot my load up her arse.I withdrew and she imediatley got of Bill and took him in her mouth as he came. I looked over to the tub and saw Claire lent over in the tub sucking one of the other bloke's prick and as he bucked she kept her mouth over his prick, taking his come into her mouth and she actually swallowed it. The three blokes left and we fell in with the others by swapping partners for the night.I ended up with Sue, 38 inch tits, aged 45 who enjoyed anal sex all night long. I eventually fell asleep withher about 2am in the morning. Claire had her first experience of a anal fuck that night with Bill, Sue's husband.In the morning Ray took her a glass of orange, he was naked with a stiff prick. Claire turned over and he fucked her doggystyle. Breakfast was a naked affair. Helen gave me a blow job as I ate my bacon and eggs. Unfortunately Helen became pregnant from that party and her and Ray have moved to the North with his job.
