Tanya and I had recently been discussing swinging. The topic came up a year ago and our past adventures lead to this discussion. We knew it was not possible to do this back home in Pakistan but was possible during one of our vacations. After a lot of planning and arranging alternatives for our parental duties, we decided to go on a 2 week vacation to the Caribbean. Before the vacation I sat with Tanya and told her how she had worked so hard in raising our kids and taking care of the family and that she I wanted her to have total freedom during this vacation. I told that she could do whatever she wanted, however she wanted to do it and that I would accept whatever she did. Tanya kissed me and thanked me. I knew my wife loved only me and that she really appreciated how I wanted her to enjoy life. The day finally came when we landed via a connecting flight at our destination. We checked into our hotel which was lifestyle exclusive. Our hearts were beating fast when we entered the hotel but we were quite surprised that the lobby area was like any 5 star hotel. After the check-in formalities were completed the receptionist handed us brochures detailing various activities hotel had planned for the next week. We got to our room and starting looking at the material. Tanya pointed to an event, which in a couple of days where all the participants have to wear masks. These masks were to be provided by the management as they didn't want even the spouses to know who was who. Tanya held my hand and said, "This our opportunity to have a free night and live our wildest dreams." Her excitement turned me on and I immediately agreed. I wanted to have sex with her right then and there but she said no and reminded me that we had agreed not to have sex with each other, but only strangers, for the whole vacation. Part 1 The resort had a few rules which we had discussed and were comfortable with. All participants had blood tests for STDs prior to registration and the hotel guaranteed our safety. All men and women were required to shave there privates, or wax, in the case for women. Our blood samples were taken and we expected the results back the next day. We had already gotten tested and knew we were clean. We went to sleep after that and the next morning went for breakfast. Tanya pointed how women were not wearing anything other than a sarong and men had only a towel wrapped around their waists. We went back to the room and changed accordingly. Tanya wore a pink silk sarong which was see-through. She looked great, she has a very athletic body and you could tell as she looked practically naked through the thin silk material. She had worked on her body and it was impossible to know that she's had 2 children. We sat next to a couple who had also checked in the night before. They were from Italy, the guy's name was Andreas and his wife Melissa were about our age. Andreas was a surgeon and Melissa was a teacher. We introduced ourselves to them and we got along straight away. After breakfast we were called to the reception area where we were told that our blood tests were back and that everything was fine. Andreas and Melissa also met us there and informed us of their good news. We were very happy to hear this and decided to relax on the beach together and have dinner later that night. Tanya told me that she really liked Andreas and would like to have sex with him. I was surprised by her being so upfront about it but Tanya was really ready for this vacation. Secretly I always have had a desire to see my Pakistani wife fuck other men and specifically non Muslim men and even have a group sex. Although I never told her this, but it was to happen in this trip. We got to the beach, Tanya wore a bikini and I wore those tight European swimming trunks. Soon Andreas and Melissa came to the beach as well. I was quite shocked to see Andreas wearing a Speedo and Melissa had her sarong wrapped around her waist like a sash, bearing her torso and breasts for the world to see. We felt overly dressed. I nudged Tanya and asked her to take her bikini off, she gave me a stare and told me that she would when she felt a little comfortable. After our whispers, I thought I should go grab some drinks for all of us. I walked off, after a few steps I heard Melissa calling my name. I turned back and she had reached me by that time, she told me that she would help me with the drinks while Andreas and Tanya got introduced properly. She winked at me. I understood and smiled back at her, and we started walking towards the bar. Melissa was a gorgeous woman, she was about 5 feet 8 inches with an amazing body, Andreas was about 6 feet tall and with an athletic built. One noticeable thing about Andreas was that his cock seemed quite big when I saw him in Speedos. I also saw Tanya giving it look too. Melissa and I reached the beach bar and grabbed a few drinks and beer. On our way back Melissa walked very close to me, my hands were full of the drinks, but she stepped in front of me and put her small hands on my bare chest to stop me in my tracks. Then giving me a naughty look she got down on her knees and undid my swimming trunks and took them off. We were in the middle of the beach area so that anyone looking our way could see my condition. I wasn't able to do anything because my hands were full and it was all to sudden. When she stood up in front of me she kissed and gently squeezed my cock. I was so crazy turned-on and my cock stiffening and straining, but then there were so many people all around us that I had to really try to control myself. I smiled at her and she took her sarong off. She had a stunning body, ample breasts and a gorgeous ass. Her pussy lips were pink and fully clean. I was amazed and told her she looked gorgeous. She smiled back and thanked me. We started making our way back to the beach, stiff cock swinging back and forth with each step I took. From a distance I was amazed to see what was happening. Tanya was fully naked now and so was Andreas, he was feeling her breasts and she was laughing. As I watched he then moved his hands to her ass and was gently groping her ass-cheeks while saying something in her ear. My cock was rock hard now and all control I had was lost. I could see Tanya was so turned on, her nipples were stiff and extended, I knew she was wet Andreas. When we reached our spot, Tanya looked up at me and smiled. Andreas immediately said that Tanya had the most amazing breasts and that he thought that they were implants and was making Tanya prove they weren't by letting him check them out. I started laughing and told him that her ass was also natural, that I was on to them. We were all having good fun. We had a few drinks, after that Melissa and Tanya were chatting about going shopping and what they like to do in their spare time. An hour or so later Andreas asked Tanya if she wanted to grab a drink and some snacks? He said since Melissa and me did the first round they should do the second round. Tanya agreed and they both left hand in hand. I told Melissa that they were up to something naughty. She smiled at me and winked and said, "Let's go watch, it might be fun." We slowly followed the pair. Then observed them entering the bar and after checking the menu and speaking to the waiter, they both walked towards a cover of some trees. This was the signal for Melissa and me and we started walking hand in hand towards the trees too. When we reached the tree line we started looking for our sneaky spouses. A few minutes later we reached a small clearing and saw Andreas and Tanya standing in the middle of the clearing kissing. They looked like animals on heat trying to crawl down each other's throats. Andreas was also rubbing Tanya's pussy and his hand and I noticed that she was dripping with her juices. I immediately started getting my erection back, Melissa noticed and gripped hold of my cock and started stroking it as we watched the couple in front of us. I started playing with Melisa's breasts and nipples. By this my wife Tanya was on her knees and sucking Andreas's 8-inch uncut Italian cock. It was fully erect and Andreas was forcing it into Tanya's mouth, face-fucking her and she was gagging but managed to suck his cock for a couple of minutes that way. Then both Melisa and I heard him asked Tanya to bend over. She obliged and took the support of a tree, as he got on his knees and started eating her ass and pussy and with his powerful hands parted Tanya's legs to get more access. He kept eating her pussy and occasionally inserted his whole tongue in her asshole. We had never had anal sex and I was afraid that he would take her anal virginity. After a few minutes Andreas got up and positioned his cock at the entrance of Tanya's pussy, he pushed her back to the tree and started rubbing his swollen cock against her entrance, lubricating her with the tip of his cock. I could see that Tanya was going crazy and was repeatedly telling him to fuck her in a gasping hoarse voice as if she'd been running a marathon. In a few seconds, he spun her around and pushed into Tanya's pussy from behind. He did it in one swift stroke he was in her. I heard a loud moan from my wife, but Andreas was not letting her rest and with a very powerful thrusts was in and out of her fully. Tanya let out a loud moan of pure pleasure as he was now fucking her slowly but with deep thrusts, taking advantage of his full length and driving his cock in and out of her pussy. He was relentless and kept fucking my wife. Tanya was moaning loudly urging him on to fuck her harder. She probably had had couple of orgasms by then. Andreas groaned and forced his cock balls deep in my Pakistani wif's sopping pussy. I could tell from his strangled groan that he was emptying his ball in her. I thought fleetingly that it was good that she was on the pill otherwise she could have become pregnant. Melissa meanwhile was sucking my cock as I stood there watching her husband enjoying my wife's body. After a few seconds Andreas withdrew and Tanya knelt down and sucked his cock clean while he cleaned her draping pussy with paper napkins he had taken from the restaurant. A lot of cum had oozing out on to Tanya's inner thighs, but Andreas wiped it all clean. Neither Andreas nor Tanya had looked over our way. We were undiscovered peeping toms. As soon as my wife and Andreas they left to - I assume - go to the bar, I grabbed Melissa and started kissing her she furiously returned my kisses. I pushed her down and ate her pussy until she orgaamed, groaning with pleasure. I then laid down on the grass and pulled her atop me so she could ride my cock. It was such an amazing sensation, she was very quick and eager, going up and down like a sex machine, trying to orgasm again as quickly as possible. Melisa was so wet that our fucking was making slurping noises. I was reaching my orgasm too soon, she was so sexy looking riding me with her beautiful eyes scrunched closed concentrating on the sensation of my cock impaling her that I couldn't hold put another moment. I grabbed a hold of Melissa's hips and rose up hugging her, with my throbbing cock inside her as blast after blast of my cum coated her insides. She squealed in delight when she realized what I was doing. Both of us were orgasming uncontrollably. Afterwards, we lay there in our embrace to catch our breath. Then we quickly cleaned each other up and rushed back towards our spot on the spot. When we got there Andreas and Tanya were still picking up food and drinks from the bar. We sat there like nothing had happened with silly satisfied grins on our faces. I noticed that Melissa quickly wiped my cum from her thighs and pussy. I gave her a kiss and a smack on her ass as well. Andreas and Tanya joined us in a little while, they had brought some sandwiches, we all ate together and joked around, Melissa asked them why it had taken them so long. Andreas started posturing, but Melissa said, "You must have be fucking Tanya to take that long, you cad." Then she started laughing. Tanya was blushing. I asked her, "You were, weren't you," and winked at her. She smiled impishly back at me and winked and started laughing too. We finally told them that we'd spied on them and who sexy they looked screwing each other like porn stars. Later we decided to chill out at our room and Andreas and Melissa joined us. Once there we decided to take a shower together. Tanya went to see if the toiletries were there. I asked Andreas if he was up for double penetrating my wife with me. I asked Melissa for her help too, they both agreed. I explained that we'd made a pact not to have sex with each other, but just with other guests, but that I was actually worried that during the duration of our stay Tanya may have to do anal with someone else and I didn't want that, I wanted to be the first to take her anal virginity. Andreas and Melissa agreed to follow my lead. When Tanya came back, Melissa called her to the bed side. I immediately walked towards the toilet. When I came back Melissa was kissing Tanya and undressing her while Andreas was taking his trunks off. Soon all of them were naked and I followed their lead. I tossed KY jelly to Melissa when Andreas decided to kiss Tanya while her back was turned towards me. Andreas was now on his back on the bed and Tanya was on top of him. She went down on him and started sucking his big meaty cock. While all of this was going on Melissa started eating Tanya's ass and pussy from behind. Tanya was dripping but Melissa didn't stop. Meanwhile Tanya was sucking Andreas's cock like a pro. Melissa now squeezed out some KY jelly and gestured to Andreas. He pulled Tanya on top of him and started kissing her passionately. I moved towards Tanya and Melissa, Melissa took a handful of jelly and rubbed it on the Tanya's butt hole. Tanya was a little shocked but continued to kiss Andreas. Andreas now hugged and locked her upper body in his arms. He then told Tanya to put her weight on her knees, she obliged. He then put the weight of his lower body on his feet and entered her pussy. Tanya squirmed but she was locked in his embrace, Andreas started fucking her slowly from below. This was Melissa's cue and she inserted two fingers soaked in lube into Tanya's asshole. Tanya was shocked and looked back behind her to see what was going on but still didn't say anything. I think she wasn't expecting what was about to happen. When Melissa's fingers had lubed Tanya's asshole sufficiently she grabbed my cock and sucked me rock solid, then put generous amount of lube on it and told me to mount Tanya. Andreas was slow fucking Tanya and from her groans of passion I could tell that her orgasm was building. I meanwhile had moved behind Tanya who for me was in a doggy style position. I positioned my cock towards Tanya's butthole. I think Tanya realized what was about to happen, she shouted and swore that I make sure it didn't hurt. I totally ignored her pushed cock in to her anal opening. As I gently pushed in, Tanya squirmed and let out a groan. I pushed deeper and gave a small thrust. I was maybe 3 inches in her, but she was tearing up and asked me to take it out. Melissa shushed her moved towards her and started kissing her, telling her that it was alright, that it would soon feel good, if she just let it happen, Melisa waved for me to hurry up and do it. In one big thrust I was 8-inches deep in her asshole. I heard a loud muffled groan as Melisa kissed my wife even harder, reaching under me to pinch her sensitive nipples. I kept my cock in her and Andreas was fucking her still from beneath. After a few moments I started fucking Tanya's asshole, slowly at first, I was so excited that I was soon pounding in her asshole. Tanya was soon groaning and moaning with ecstasy with one cock swelling in her cunt and another in her asshole. Soon my wife was hit by waves and waves of orgasms. Melissa was now behind me and licking my asshole as I thrust into my wife. Her well lubed fingers were soon knuckle deep in my asshole and rubbing my prostate. It was a strange feeling having a wiggling finger inside me as my cock swelled and suddenly blasted my cum like a jet fighter shooting bullets. This was the most I had cum in my life, I almost passed out, my orgasm was so intense. As soon as I was done, and could go no more, Andreas moved from under Tanya, pushing me to one side and entered Tanya's sloppy ass and pumped her for another minute or two. He too emptied his load in Tanya's behind. We both were exhausted meanwhile, Melissa was eating Tanya's ass and eating up all the cum like a cream pie. We left Tanya on the bed to take a rest and the rest of us went into the palatial bathroom to take shower. In the shower Andreas and I both fucked his wife Melissa. We sandwiched her between us and ate her pussy and ass to return the favor. We were soon joined by Tanya and her gaping holes. We left the girls in the shower where Melissa and Tanya made out. After this we discussed the masquerade party that was coming up tomorrow. Andreas and Melissa told us that they were looking forward to it and had also registered.
