Following Helen’s and my first successful foray into the world of MFM fun, we discussed and decided that we wanted to experiment further to broaden our horizon. The opportunity for this arose when we had booked a rental bungalow in Italy in summer. The bungalow stands at the edge of a village and has a lovely garden and swimming pool both of which are shielded from prying eyes. So Helen and I were sunbathing, swimming and eating in the nude out in the garden from dawn to dusk. It was wonderful to be in the nude all day, to have Helen around all day not wearing a stitch and to enjoy the sight of her slim figure all day. She is a slim brunette with smallish and firm breasts, well-proportioned buttocks and a clean shaven pussy. Likewise I am the sporty type, tall and also with my pubes completely shaved. We sometimes joke about our shaving saying that you are only fully nude when you are fully naked in the genital area. Helen always says that my cock looks more prominent when it is shaved. But I know for a fact that what she really means is that men’s cocks in general look bigger when shaved as she often openly checks out other men’s physical features and compares cock sizes on the nudist beach or in the sauna. I on the other hand always take delight out of Helen’s nudity on those occasions, especially her exposed pussy lips which glisten with moisture when she is aroused. It is on those occasions that she is not bashful and allows more than fleeting glimpses of her pussy to others. We met a very nice Dutch couple, Ann and Aarie, during that holiday. Both speak excellent English, are good-looking and in the age bracket as Helen and I (mid/end 30s). We invited them to our bungalow for lunch and the afternoon. It was another hot and sunny day, so we decided to have a little swim in our pool before lunch. We had got to know Ann and Aaarie as relaxed and liberally minded people. So Helen and I were hardly surprised when they followed our lead and took off all their clothing. Not that there was a lot to remove: Ann removed a short summer dress and she was naked beneath. She revealed a sexy body, slim and firm with a shaved pussy. Aarie pulled off his vest and then took off his shorts to reveal a naked body that looked athletic. He is also clean shaven. Both he and Ann had an overall tan suggesting that they too had been sunbathing in the nude. I must confess that they looked even more attractive in the nude than in their clothes. I am sure Helen felt the same. In the meantime, Helen had peeled off her wrap-around sarong, and like Ann she was also not wearing anything else. I had followed suit and removed my t-shirt and shorts. So there we were, the four of us, all naked and jumping or stepping into the refreshing pool water. At one point while Helen was standing at the edge of the pool, I grabbed her, held her tight and planted a kiss on her lips. She responded by opening her mouth, and our kiss became a full-blown passionate French kiss. When we broke off, I said to her:” I love you, darling.” “I love you too, my lover husband,” she whispered. When we got out of the pool for lunch, we dressed again, Aarie and I again with our t-shirts and shorts. Helen folded and wrapped the sarong around her naked body and tied it over her breasts so that her shoulders were left bare and the fabric made a very short dress that was not even mid-thigh. She also slipped on her high-heel sandals and looked very appetising. Ann put on a lovely small g-string bikini which she had brought along and which tied at the sides. Her bikini top was a smallish triangular piece of fabric that just about covered her breasts. She too looked absolutely stunning. We had lunch on the terrace in the most relaxed and sociable atmosphere one could imagine. There was some banter, flirting among all four of us and the odd sexual innuendo. It turned out that Ann and Aarie are nudists spending all their summer holidays in nudist camps or campsites and had also done some soft swinging. This could be interesting! After we had finished our lunch, we decided to play a few rounds of darts. So I brought the darts out onto the terrace where there was a target fixed on the terrace wall. Some rounds were played, with everybody being a winner and a loser from time to time. It was then Aarie who suggested that we continue playing for wagers. I think Helen knew what he was trying to get at. But faking ignorance, she asked:” Like what?” “Everybody who loses a round has to take off a piece of clothing,” was Aarie’s reply. Everybody agreed, so our game entered a second and more exciting phase. Helen grinned when she said she was fine with the new rules. Aarie the instigator lost the first round, so he took off his vest. The next round was lost by me, and I pulled off my t-shirt. Next one to lose a round was Ann. As she was wearing her small bikini, she had to reveal either her breasts or her pussy. Like a dancer in a strip show, Ann slowly reached to her neck and in slow motion untied the top strings of her bikini top. She then reached her arms behind her back and with the same dramatic effect untied the lower strings of her bikini top. Her beautifully tanned breasts were revealed. The next loser was again Aarie. When he removed his shorts it was obvious that he was sporting a semi-erection. I am sure I saw a smile flash over Helen’s face. Round 5 beckoned and this time it was Helen who lost. She bent down to remove her sandals when Aarie called out:” Oh no, Helen, sandals are footwear, not clothing.” “Oh really? Well then.” Helen replied coquettishly. With this she grabbed the knot on her wrap-around sarong and untied it. She made a few dancing steps and then unwrapped the sarong so that her naked body came into view. What a wonderful picture: this woman, naked but for her sandals, self-confident, she happened to be my wife. I was immensely proud of her. But when I lost the next round and removed my shorts, not only was I proud but also so excited that my cock had also grown to a semi-erection. The next round saw Ann lose. In her usual theatrical manner, she pushed her hands under the waistband of her bikini g-string and with a “tatatata” she slowly pushed the g-string down her legs. As she pulled it over her feet she bent down offering us a wonderful (and, I am sure, quite deliberate) view of her toned buttocks. Again the four of us were facing each other completely naked as we were, but this time in a much more erotically charged atmosphere. The situation become even more tense when Aarie suggested:” If you are happy then we can continue with the following rules: when somebody loses a round, the loser’s spouse can impose an instruction on the loser. No instruction can be used twice. Are you all happy?” Helen expressed her agreement first, followed by me and then Ann. This was going to be like strip poker or spin-the-bottle, and I was curious to see where this was heading. Helen looked flushed and we smiled at each other. I thought that she was equally excited about this adventure. I lost the first round. And after some reflection Helen said:” Come and kiss me.” As I walked up to Helen, our eyes met. We kept the glance and it spoke of understanding and mutual love. I was confident that whatever happened this afternoon, it would be fine. When our lips met, I found hers wet and waiting. Our lips opened and we explored each other’s mouths with our tongues. A deep passionate kiss. Eventually we stopped kissing, and the next round ensued which Aarie lost. Ann instructed him to step behind her and massage her breasts. First he cupped her breasts before he started to gently knead her nipples with his fingers. Ann had her eyes closed, she was breathing deeply and it was clear that she was becoming increasingly aroused. Helen and I were standing arm in arm, watching their show with growing arousal. As Aarie finished the massage and was ready for the next round, his cock had grown to a full erection. I caught myself out thinking to myself:” So this is the cock that Helen will be enjoying later on.” I found the idea intensly erotic. And my cock was responding to this idea by becoming fully erect. The next round rolled on and it was Ann who lost. Aarie looked from person to person, clearly reflecting and eventually said:” Why don’t you stroke my cock?” She walked behind him, reached around his waist and seized his erect cock with one hand. She pulled his foreskin back and it became evident that his cock was leaking pre-cum profusely. Ann moved her hand slowly up and down along the length of Aarie’s cock for a minute or two. It seemed that she knew what she was doing as Aarie was breathing fast. She tightened the grip of her hand around his shaft and then stopped wanking him. Clearly she did not want him to come too soon. She released his cock and planted a quick kiss on his lips. The next round saw me as a loser again. This time it took Helen no time at all to come up with her instruction. She must have been pondering it beforehand. “Lick my feet and toes, honey.” Before I could answer she removed her sandals. She lied down on a sun lounger, rested her feet on its foot end and raised her left foot into the air in my direction. I walked over to her and sat down on the edge of the lounger. I had a phantastic view up her legs and knew that Ann and Aarie who had come closer, would also be able to have an unobstructed view of Helen’s shaved pussy. I leaned forward and began by kissing the little toe of her left foot. Then I went on to kiss her other toes as well, eventually I stuck my tongue out and licked my way back from big to small toe. On my journey back to her small toe I made sure to slip my tongue between her toes. Helen was breathing heavily and letting out quiet sighs when I started caressing her calf and upward her thigh, but just stopping short of her pussy. With a final journey of my mouth and tongue along the row of toes on her left foot, I eventually finished my ministrations on Helen’s foot and toes. It was obvious that she wanted more but I wanted to keep her in suspense. She put her sandals back on with a giggle saying:” I don’t want to be completely naked, do I?” Helen lost the next round. So it was my turn to impose an instruction on her. I knew what I wanted Helen to do although it was a bit wicked. “Honey, go and get your lovely big glass dildo and pleasure yourself.” Helen looked at me for a second, almost as if in disbelief. Then she disappeared into our bungalow but was back within a flash holding her glass dildo. “It’s show time, guys and girl,” she said and lied down on the sun lounger. She bent her knees and allowed her legs to open up. Her pussy came into clear view and it was obvious that her pussy lips were engorged and wet with moisture. I could tell that she was on fire. She slowly reached down with her hand and brought the dildo towards her pussy. She moved it in circular motions over her clitoris which brought out a whimper of lust from her. Then she pushed it inside her pussy, first a few inches, then all the way. She started moaning as she rhythmically moved the dildo in and out of her pussy. Her eyes were closed, her head thrown back and her other hand was pleasuring her clit. It was highly erotic to see Helen masturbating and to witness her sex play. I looked over at Ann and Aarie and they were clearly enjoying Helen’s sex show. They were standing arm in arm, intently watching every movement of Helen’s hand and the fucking she was giving herself with her dildo. I realised that Helen was working her way towards an orgasm which I did not want to happen too soon. So I walked over to her and grabbed her hands to prevent her from cumming. She opened her eyes and whispered to me:” Darling, I am so horny.” “Stating the obvious,” Aarie replied. We all laughed and resumed with our next round. Once again, it was I who lost. I looked at Helen in expectation wondering what she could have in store for me. She appeared as if she pondered, looked at me and then said:” Lick Ann’s pussy.” Wow, I did not expect this to happen so soon, we were heading towards a full swap. “Are you sure?” I asked. “Yes, I want to see you giving her oral. But don’t bring her off. Not yet anyway.” I looked over to Ann to see how she felt about this. But she had already placed herself on the sun lounger and opened her legs. Her shaved pussy and engorged pussy lips were extremely inviting. So I bent down in front of her and started kissing my way up her legs. Her pussy lips were moist and I could smell her sweet sex aroma. When my mouth made contact with the soft flesh of her pussy she let out a soft moan. I kissed her pussy lips several times before I opened my mouth and started encircling her clitoris with my tongue. Then I darted my tongue out and penetrated Ann’s pussy with it as far as it went. I lapped up the love juice leaking from her pussy, and Ann was clearly approaching her climax. She thrust her pelvis up so that her pussy and my mouth ground against each other. Helen realised this and said:” That’s enough for now, darling.” It was amazing how much control Helen was assuming in this situation. As to me, I was probably as disappointed as Ann to be separated from her pussy. Our next round was lost by Ann. Aarie looked at me and asked:” Would you be happy to have your cock sucked by Ann?” Before I could answer or ask Helen, Ann had come towards me and squatted on the floor in front of me. My cock was rock hard anyway so it needed no preparation. She slowly kissed and licked her way along the length of my cock before she opened her mouth to swallow it in her mouth. She performed miracles with her lips and tongue as she pulled her face away from me, just to accommodate my cock in her mouth again a few seconds later. Ann built up a lovely rhythm. I looked at Helen who was standing there, arm in arm with Aarie, and she was gazing at Ann as she was giving me this expert blowjob. I was in heaven and was even more aroused when I heard Helen say:” Wow, this is so sexy. Almost as sexy as if I were giving him a blowjob.” I then noticed that Ann was letting off and let my cock slip out of her mouth. She planted a last kiss on it and said:” End of show. You are not yet allowed to come although I would have liked to have your spunk in my mouth.” So to my disappointment the next round rolled on. It was Helen who lost. I was wondering which dare to impose on her but eventually said:” Helen, honey, go and sit on Aarie’s lap and do some French kissing.” Helen said:” Fine with me.” She got up and walked over towards where Aarie was sitting. She was the most erotic sight as she approached him, her heels clicking on the terrace floor and she was slightly swaying making her bum move in the most provocative manner. She bent down to Aarie and kissed him on his lips. Their lips opened and I could see how their tongues were dancing around each other as their kiss became ever more passionate. Ann and I were holding hands and were watching with excitement how their kissing evolved. Ann and I also had a perfect view of Helen’s legs, accentuated by her sandals, and her bum which was showing in our direction. She opened her legs wider, so because she was bent over Aarie, Ann and I could clearly make out her rosette and her pussy. “What a sexy wife you have,” Ann said admiringly. Then all of a sudden Helen broke off the kissing, turned around and sat down on Aarie’s lap in cowgirl fashion. She was thus facing Ann and me. What happened next was almost like a movie in slow motion. As Helen lowered herself on Aarie’s lap, she reached down with one hand and guided his cock towards her pussy entrance. She began to rub it along the length of her pussy. She moaned and closed her eyes. Then she slowly and gradually impaled herself on Aarie’s cock which was soon buried in her pussy all the way. “Oh, I needed this cock so much. It feels so good in my pussy,” she whispered. Then Helen’s and my eyes locked and she whispered to me;” Fuck her, darling.” I did not need a second invitation. So I looked at Ann and stepped behind her. She bent over her upper body sticking out her bum towards me. I moved closer to her so that my cock was resting against her pussy entrance. I slowly pushed forward and my cock slid into Ann’s very well lubricated pussy. I was in paradise: while I was pumping my cock into and out of Ann’s pussy in a slow and steady rhythm, I could admire her lovely bum. At the same time, I could follow Helen and Aarie’s sex show in front of me just a few metres away. Helen was riding up and down on Aarie’s cock while she was stimulating her clitoris with one hand. We were all panting and moaning in rhythm with our fucking. We all came pretty much at the same time. First Helen announced her approaching orgasm, then Ann contracted into her climax before Aarie shot his spunk deep into Helen’s pussy before my spunk erupted into and flooded Ann’s pussy. Once we had disentangled from each other after some time, the four of us were standing in a circle facing each other, smiling, chatting and laughing. Aarie was exchanging kisses with both Helen and Ann, as did I with the two ladies. They stayed the night with us and suffice to say, we had some more swapping fun together.
