I had only going out with Sheila for two weeks and this beautiful creature had banged my brains out nearly every evening. Then she dropped a bombshell on me that she was off to a Spain for a week with friends. She then asked if I would like to go with her. It would cost me £130 for the flights and everyone threw in £350 for food and transport. The thought of a week with Sheila in the sun for a week had me sold. She told me that it was always a wild affair and don't bother to pack many clothes. The plane landed and as the doors opened the heat hit me. Once passed immigration. Sheila found a group of other people mostly in their twenties, but one couple was nearer to forty than twenty. There was twelve couples and one single man in the group. We had three cars and a mini bus waiting for us. Thirty minutes later we were at an old hotel that had seen better days. It was clean but a little shabby. It was now let out for groups for self service use. The room that Sheila selected was clean and comfortable. We dropped our hand luggage and sheila said she wanted to see the swimming pool. We found it and to my surprise it was in better condition than the rest of the hotel. Sheila ripped all her clothes off and dived straight in. From the water she called for me to get in. I said that I didn't have my trunks on. Before I had finished telling her, two more couples were stripping off and diving in. I noticed one of the men had a huge cock. Then a ball was found and a game started up. I was a little shy but not wanting to be a spoil sport I undressed and jumped in and joined that game. I was enjoying the tits bouncing around as the girls jumped for the ball. Then the older couple appeared. They were already naked. They sat on a couple of loungers. From the lower position in the water The woman's pussy was clearly visible as she moved on the lounger. Then we heard a gong and everyone seemed to be getting out and going towards what was the main lobby area. Everyone was there and to my surprise they were all naked. One of the men climbed onto a chair to get everyone's attention and held up a sheet of paper and announced that it was the schedule of duties for each couple. He pinned several copies on the notice boards. The second sheet was for entertainment. He pinned copies next to the schedule. Then he said enjoy and walked away. Sheila an I looked at the lists. I was on evening Washing up duties, Sheila was on kitchen duties for lunch time. The other list showed morning afternoon and evening games. They ranged from swimming competitions, swimming volley ball, football, cricket and archery. The evening entertainment was things like karaoke, bingo, fancy dress, cards and MR & Mrs. The final night was party time. I thought the fancy dress was funny considering at that time everyone was naked. Sheila and I enjoyed the pool until she had to go for her kitchen duties, I stayed in the pool. The ball game was going on and as one of the girls jumped for the ball she landed on me. We were under the water when I felt a hand grab my cock and then it was gone. I assumed that it was an accident and dismissed it. A short while later one of the men grabbed a girl to prevent her getting to the ball. Quite harmless, but it was not his partner and he had grabbed her by her tits. Again as they quickly parted I dismissed it. I got out and sat on a lounger watching the game. One of the girls also got out and sat on the lounger next to mine. " My name is Melanie," she told me, "your with Sheila aren't you." I told her I was. "She's a wild one," she continued, " she is always the sole of any party." With that she left to get a cooling drink. I knew Sheila was wild in bed, but I had not seen any wild activity any other times. After lunch Sheila dragged me to the bedroom and we screwed for some while. When we lay recovering we could hear at least two couples following our lead. One of the women was particularly loud screaming things like fuck me, fuck me harder. Sheila said she was going for a drink and as we left the room where most of the noise came from a couple came out still naked. She did not arrive with the guy she was with at the site. When we were out of earshot I said to sheila that's not her boyfriend. Sheila laughed then said, "I didn't tell you,in case it scared you off, but most of the people are swingers. We got our drinks and sat somewhere a little quieter. Sheila told me that she was into swinging and had every intention of enjoying herself, as for me If I didn't want to participate I didn't have to. She went on to say that if I didn't enjoy it then when we got back home our chances of staying together was slim. We joined in an archery session. Sheila was good at it. Then I went to the toilet. On my return I couldn't see Sheila. I wandered around for a while. Then someone asked me was I looking for Sheila. I told them yes. They informed me she was the entertainment in the games room. I thanked them and made my way to the games room. I was shocked Sheila and another girl were laid on their backs on the pool table with their heads hung over the edge backwards. Each had a cock in their mouth, Sheila had another in her hand end each had one pumping away at their pussies. My girlfriend was servicing three men the other girl was servicing two men. I couldn't believe what I was watching. My cock did and it was soon at full mast. The other girl see me at her side and waved for me to step forward. As I did her hand grasped my cock and started wanking me. The three people on Sheila rotated round and seemed quite happy to service the cocks in the new position. Then the other two men on the girl holding my cock started to rotate. I found my cock in the girls mouth. A while later those with Sheila rotated again, and I watched as she took her third cock in her mouth and a third cock in her fanny. Then my group was rotating and I was between the girls legs about to penetrate a girl that I didn't even know the name of. Then I was in. She was tight and hot as I pumped away at her fanny. Then I lost it and pumped my load deep into her hot hole. I staggered away and went to clean myself up. Back in the room I cleaned myself up and lay on the bed wondering quite how that had happened. Eventually Sheila came into the room saying that she needed a shower. I wasn't surprised as she had spunk still running down her legs and some on her face and in her hair. When she came back from her shower she asked if I had enjoyed Sofie. I told her I had. She told me there was much more to come and just enjoy it. She told me that we will always end the evening together in bed whatever happened during the day. After the evening meal I finished my cleaning duties and went to find Sheila. She was sat quietly drinking a cocktail. The other side of the room two girls were totally engrossed in a 69 and on the next sofa two men were tag teaming a small blond girl. Sheila teased, "Which one do you fancy." I told her that the redhead in the lesbian pairing looked tasty. Sheila went over and whispered to her. She nodded yes and Sheila returned to me. "Go on then," she said to me, "Pauline is happy for you to join them. Pauline was the one on the top. Sheila dragged me other and placed my hand on Pauline's arse. As I stroked it my cock sprang to attention. Sheila grabbed my cock and steered it into Pauline's fanny pushing me in by my arse. Pauline's groans into the other girls fanny told me that I was hitting the right spots or the girl was with her tongue that occasionally brushed my cock. I unloaded my cream from my balls into Pauline's fanny. As I slipped out the girl underneath was sucking my spunk greedily out of Pauline's Fanny. Sheila disappeared twice during the evening. I could only guess why. Then when we met up again and retired for the night. It dawned on me that I hadn't worn any clothes today. In bed she played with my cock and balls as we talked. She asked had I enjoyed myself. I told her I had. She told me that the only rules I needed to know was that If I fancied a girl I had to ask if she agreed or a girl asked me then I could do whatever pleased us both. I fell asleep with my hand between Sheila's legs and her holding my cock. The week seemed to go too quickly and I screwed two to three girls a day always making sure that I pleasured Sheila. Then on about the fifth day the Older woman in the group came up to me and whispered in my ear that she wanted me to fuck her silly. I just looked with a shocked look on my face. I had never had a woman just come up to me and tell me she wanted a fuck. As I hadn't said no she dragged me to the couples bedroom. Her partner was sat in an armchair and watched as his wife ravaged me. She sucked my cock and balls. Rubbed her fanny all over me, especially my mouth, Then rode me cowgirl until I exploded in her fanny. Her partner came over to us and shook my hand thanking me the dived head first into her fanny, licking my cum out of her. I couldn't believe that a man would thank me for fucking his partner, but he did. When I told Sheila, she laughed saying that Brian couldn't get it up too often these days and he needs all the help he can get. Then on the Morning of the last day, Sheila warned me to save myself for the evening and just grinned at me. The day was fairly quiet and unlike the previous days there was a little petting going on, but no outright fucking. Then after the evening meal was cleared away some chairs were placed in a circle looking outwards. Then we were told that the party game was ready and the men to take to the seats. I sat on a seat and listened to the rules The rules were that the girls were to circle around the men and when the men stopped the women had to sit on the nearest lap. The last woman to take to a lap would eliminate the man and herself. A prize would come for the winning couple. The music started and the girls started circling the men. The old man was operating the music. Then the music stopped and I had a girl wriggling on my lap causing my cock to grow. Two people were eliminated and left the circle. After the second pause in the music the girl jumped on my cock and buried it deep inside herself. another couple left. Then the music stopped again, the old woman sat berrying my cock in her fanny. Whilst the next couple was being removed the old lady told me that she would have liked more of my cock. Then the music started and she was off my cock and gone .I had another girl sit on me and then the following round I was out. The girl took me to some of the other chairs and straddled me sinking my cock back into her fanny. I came quickly as she wriggled about on my cock. The game ended with Sheila sat on the spare man that was with the group. Sheila fucked him until he came. The the old man gave them a small packet each. Sheila came over to me. The girl still sat on my cock as she said, " I suppose I had better give this back to you," pointing to my now limp cock. There were a few more games one being put the tail on the donkey whilst blind folded, the tail was a large double ended dildo. Who's fanny is it The girls were on the chairs kneeling with their fannies pointing outwards. The men took turns blindfolded and were steered to a fanny. You could finger it and lick it then guess who's fanny it was. If you were right you moved to the next fanny. If you failed you was out. Then the party proper started with music and dancing. I was grabbed by Sheila and dragged onto the dance floor. She was soon whisked away by other people. The old woman grabbed me in more ways than one. She wrapped herself around me as we swayed together and steered my cock to her fanny. I was a first for me, being screwed on the dance floor. Due to our height differences i kept slipping out and she eventually moved onto someone else. Another girl grabbed me and dragged me to the Games room. Sheila was doing her party piece with two men on the pool table. The girl bent over the table whilst still standing on the floor. I definitely pinned the tail on this ass. I slipped in and slowly screwed her, not wanting to finish too quickly and also watching my girlfriend sucking and fucking two men. All good things come to an end and I slammed into the girl and gave her my cream. She thanked me and left to go back to the dance floor. I sat on a chair and watched as the two men rotated from mouth to fanny several times before she had one load in her mouth and over her face and the other in her fanny. I screwed one more girl that evening as her partner encouraged her to fuck me and to suck his cock. Then a couple of rugs were placed on the dance floor and a call went out for any takers. The old woman and Sheila stepped forward. They laid down on the rugs and any man still with a boner took turns on Sheila and the old woman. I had finished an was unable to get hard so just watched as the two of them had cocks rotating from one fanny to the other. Sheila was the first to say stop, she couldn't take any more. I took Sheila off to bed leaving the old woman still screwing whoever wanted a turn. Back home Sheila told me that she went on these holidays twice a year and that she attended parties and if there wasn't any and she was in need of cock she would go dogging. I had never heard of it. She took me to a dogging site that Friday evening where she sucked and fucked six different men. She could never have just one cock. I was ok with her extra marital activities and married her a year after meeting her.
