Jenny was intending to spend the weekend at my place anyway, it was Friday. We showered and ordered pizza, we had intended to go out, but decided that a night in was in order. We didnt finish the pizza, instead we fucked like snakes on my living room floor, then again in the comfort of my bed. When neither of us could fuck any more, we lay in each others arms and discussed our day. Did we want a repeat? Could it be as good a second time? And the most burning question: swapping. I was in no doubt whatsoever that I would fuck Sara senseless, given the chance, but how would Jenny react? She was a keeper, I didn't want to risk losing her. She is fantastic in bed, up for anything but also inventive. We are as well matched as a cock and a cunt. She is very beautiful, intelligent and amusing. Would swinging spoil all that? Tentatively, I asked; "Could you accomodate a cock like Paul's?" I felt her squirm. "I don't know," she said softly. "I have never had the oportunity." "But you're considering the possibility?" I probed. She jabbed me hard in the ribs. "So you read minds now?" She said. "I suspect every woman wonders what it would be like. How would you feel if I tried?" "Can I sell tickets." I joked. It rained all weekend, we spent much of the time fucking. Hardly a wasted weekend, but by Sunday my cock needed a rest. As she left, Jenny said quietly; "Text them. Just suggest meeting up for a drink somewhere." I did and we did. On a Tuesday, in an almost deserted pub. Sara told us their story. She was Swedish, shattering my image of slim Swedish blondes. "We are married," she said, adding with a grin; "To each other." "We love each other. We fuck other people, but with each other's approval and only when we are together. If I had to choose between our lifestyle and Paul, I would unquestionably choose Paul." Paul chipped in; "I feel the same, Sara is my world, the rest is just play." He really was a man of action, not words. But he could use them when he chose to. Sara continued; "Sex is what holds us together, our glue. Neither of us can remember a time when sex was not our driving force. Two years ago, we decided to push the envelope. We had a holiday in Prague. We had heard that it's now the naughtiest city in Europe, surpassing Amsterdam and Hamburg. On our first night, we visited a live sex show. We loved it. During the break, they asked for volunteers to come up on stage and perform. Our food and drink bill would be torn up as a reward. We volunteered. I had fantasised at being watched fucking, not by a crowd perhaps, but I was wetting myself at the thought. We stripped naked in the dressing room and a woman applied stage make up to us both. She couldn't speak a word of English, but she was mesmerised by Paul's cock. On stage, we did a little sexy dance, then Paul lay on the round couch thing and I sucked his cock. Then I mounted him. We fucked in public. The audience loved it, they were shouting something that we could not understand. Then a voice came over the loudspeakers in English; 'They want to see him come, wank him off.' I did. It was a good one wasn't it Paul?" Paul just nodded. Sara went on; "Like a fountain, I had never seen it shoot so high." Paul spoke; "It was the situation we were in, I discovered that night that I am an exhibitionist. On the right day and with an audience, I can shoot down Clay-pigeons. " That I would like to see. Sara continued; "We went there every night. Sometimes there were other amateurs willing to volunteer. If not, we did. We performed three times. On our lasy night, they asked us if we would perform with the professionals. We did. The pros followed a script, a situation was acted leading to the fucking. Nobody would win acting prizes, it was easy to go along with the preliminary action. Paul got to fuck a stunning blonde, coming all over her face. I was triple- teamed by three hunky, well hung black studs, they shot theirs all over my body. I nearly fainted with lust. Last year we went to a swingers resort in Spain, we loved it. Everybody was nude, if you wanted fuck you just did, others just watched and wanked, including the women. If you wanted to fuck somebody you just asked. I lost count. Being naked keeps you permanently horny. We couldn't afford it this year, so we joined a naturist club thinking that even if the uptight Brits didn't want to join in, they would not mind if we fucked each other. We were wrong, they asked us to leave. Why? What harm can it do if everybody concerned is an adult and there is no coercion." She turned to me. "So here we are. And in case you're wondering, yes, I would love to suck your cock, right here if they allowed it." She turned to Jenny; "I would also like to watch you impaled by Paul's cock. You're fucking gorgeous, I don't suppose you do women?" Jenny spluttered. We parted having been given plenty of food for thought. I was up for it, it would depend on Jenny.
