Jenny could not resist ths temptation to try a really big cock. How big? I never measured it. Sara said nine inches. I can believe it. My research suggests that to to be in proportion, a six foot tall man should have a six inch long cock. Plus or minus half an inch. I'm six feet tall and a plus. It figures then, that a man half a foot taller than me should possess half an inch or so more in the willy department. Perhaps seven and a half tops. Paul was beyond standard deviation, out of proportion. Mine's quite thick, just under six inches in girth. Paul's was thicker. Again not measured, but by observation. Not only could it reach parts other cocks couldn't, it ploughed its way there like a bulldozer. Not fair. But every woman's dream. Jenny was about to have her dreams come true. We agreed to meet at their house. Jenny practised. Not with me, although I reaped the benefits of her quivering arousal. I did not possess the required equipment. That came made of plastic. Jenny had walked into a sex shop and purchased several dildoes, ranging from big to Paul. Surprisingly, she could take the biggest without real difficulty, all the way to it's plastic plums. I was impressed. I was equally impressed by the way that her cunt still felt tight around my cock when I frantically fucked her as soon as the thing plopped out. She was ready. We dressed for a night out, even though the main event required for it all to be removed. Jenny wore cock-stiffening undies, but chose hold-ups over sussies. She hid the lot with a short cocktail dress. I wore a suit, but no tie. Sara and Paul were more casually dressed. Sara had cooked a meal, she was an excellent cook. But everything was just foreplay, we all knew what we were there for. Paul and I actually tossed a coin to decide who went first. I won. We had considered using separate rooms, separate beds. Synchronised fucking. But that would defeat the object. Watching and being watched. We trooped to the bedroom and undressed. I was concerned that my cock would get stagefright, but Sara ensured not. She knelt in front of me and gave me an expert suck. She could give lessons. I had to pull her off. She spread herself on the bed. My turn. I seemed to give satisfaction, she came quickly, pressing my face into her groin as she shuddered her way through a big one. I mounted her missionary style. I was pleasantly surprised about how tight she was, considering her usual fare. She came again as I fucked her, audience forgotten. This really was a truly sexy woman. She clung to me as my spunk flooded her, encouraging me, saying; "Fill my hungry cunt with your thick spunk, I want it all." I think I gave it to her. I slipped out and stood, suddenly concious of my audience. Jenny and Paul were sat on small, two seat sofa that really made the room crowded. Presumably shoehorned in to provide a grandstand for the bed action. His arm was around her with his hand holding one lovely tit. His other hand was at her crutch, hers was gently wanking his traffic bollard. I looked back at Sara, she was still splayed on tthe bed, cunt gaping, spunk leaking back out. She raised herself on her elbows and said; "Jenny's turn." I helped her off the bed. There was a wet patch. Paul stretched out on it, lying on his back. Jenny's first experience of Paul's cunt-stretcher was to be with her on top. On Sara's advice. In this position, Jenny would be more in control, able to regulate speed an depth of penetration. Jenny lay alongside and took Paul's cock in her hand, avoiding the exposed gland, just wanking the shaft. It didn't look so big in her hand and I realised how small Sara's hands were. I looked down to where she was gently stroking my re-erected tool, sure enough, her small hand made it look huge. Jenny lowered her mouth to Paul's, holding it upright. Unlike a normal sized one, it was not quite self supporting. The large volume made it too heavy for the hydraulics that keep a cock in position. It needed help. It looked like Jenny was attempting to fit a huge Victoria plum into her mouth. But she had practised with the dildo and inside it slipped, along with several inches of thick shaft. Eye-watering. Eventually, she positioned herself astride him, paused to apply lubricant to her opening, as she had with the dildo, then used her fingers to position his bulb at her entrance. This was it, play was over. This was the serious part, I was about to see my beautiful partner take another man's cock. I held my breath. Our 'grandstand' gave us a very close view from the foot of the bed. Sara's grip on my cock tightened. It was like slow motion. Slowly the monster disapeared into her slim body. Where the fuck does it go? She bore down on it for what seemed an age, then raised up, revealing his thick wet shaft. Slowly down again, then again until she was fucking him. I breathed, the deed was done. She leaned forward, brushing her nipples on his chest. His hands came round to hold her shapely arse as he took over the movement, thrusting up into her. Whether by accident or design, he didn't last long. Impaled on his impressive weapon was a very beautiful woman, no doubt with a much tighter cunt than his regular mate. He stopped his thrusts with his cock buried deep, we saw his balls lift and then he was pumping his seed high up inside her. Jenny had not come. Nervous perhaps or just too quick. She lifted herself off him, his cum made silver strands, joining them until they snapped. Jennys cunt gaped, spunk welled back out. Paul had been generous. Jenny dismounted and lay alongside him, chest heaving, legs splayed, cunt oozing. Live porn. Sara's voice broke my trance. "Reclaim her," she said. "Take back what's yours, fuck her now while she's wet." My heart leaped, my cock swelled in Sara's hand. Sloppy seconds. The stuff of my dreams. I stood, cock in hand. Jenny opened her eyes, realised my intentions and held out her arms. My cock needed no guiding, finding the well prepared target easily and for the first time in my life, my cock entered a cunt wet with another man's warm spunk. The feeling is indescribable. I could hear the squelch as I displaced Paul's cum with my cock. Looking down into Jenny's eyes, I began my movements. Very carefully. Despite my recent come into Saras accomodating cunt, I was very close. With a supreme effort to control my climax, I began to fuck Jenny. She orgasmed very quickly, boosting my ego, she had not come for Paul, despite his superior equipment. I was not far behind her. I grunted as I discharged powerfully. As my spurts jetted into her, Jenny looked up at me and mouthed; "I love you." We left, saying that we would be in touch. We travelled home in silence. Only when we were in each others arms, naked in her bed, did we speak. "How was it?" I asked softly. "A bit painfull," she confessed. "Well, not really painfull, uncomfortable. It would take some getting used to." "Would you do it again?" I pressed her. My cock was bursting, her debauch had made we want her more than ever. "Ask me in the morning. For now, just hold me." The next day, we discussed our future, not just with Sara and Paul, but with each other. Did we have a future together? Would swinging, silly word, but I can't think of a better one, have any part in it? Jenny had been married previously, but I knew very little about him or her past. Jenny was good to be with. But forever? Our discussion was full and Frank. The same questions were running through her mind. We made some decisions. We would live together, in her flat to begin with, it was bigger than mine and closer to both our jobs. My younger sister was looking for a flat to rent with her boyfriend. They would be ideal custodians for my flat. As for Sara and Paul, we would go with the flow. Not our usual style, we both prefer to lead, but there was no doubt that we were rookies at this swapping thing. It was exciting and intriguing, we were both driven by curiosity. With Sara and Paul, I knew that I was not getting the best of the deal. Sara was lovely, but really not my type. Jenny was a stunner, Paul had the best of the exchange. Jenny said that she felt no real attraction for Paul, his only asset was his donkey-dick, any woman should have that experience at least once. We invited them round for a return match. At 'ours'. Jenny cooked. A simple meal, no doubt Sara had the advantage there. We had squeezed two chairs into the bedroom for the spectators. This time Jenny and Paul opened the batting. He licked her cunt and made her come, then mounted her from above, she fed his meat inside, this time quite easily, she had been practising with Plastic Paul. Sara knelt in front of me and sucked my cock. I felt like a Roman emperor being entertained and served by my slaves. Was this the real me? A voyeur? Preferring to watch my woman being fucked by another man? Perhaps. The emperor made a decision. I allowed my cock-slave to suck me off. Rewarding her with a mouthful of imperial spunk, which she gratefully gulped down. Then started again. On the stage, Paul was now pumping vigorously into my Empress' cunt. Her fine tits swung enticingly beneath. They changed again, Jenny on her back again. But not to be fucked again. By prior arrangement, Paul finished himself by hand, shooting the result of his efforts all over Jenny's front, from her widespread cunt to her lust contorted face. Streaks of very white cum decorating her. It was our turn. My turn to fuck Sara around all points of the compass, from the front, from behind, her on top, facing and reversed. Then came my agreed finale, fucking her generous tits, giving her a splendid pearl necklace. We met up approximately every four weeks, agreeing that too much would over-egg the pudding. On those occasions, we explored every variable that two couples could think up, including threesomes. This meant that the odd man out, or woman, was reduced to mere spectating. And of course, wanking. This allowed each man the rare pleasure of having his cock sucked by two women passing the cock from mouth to mouth, having his cock and balls sucked simultaneousy, having his arse rimmed while his cock or balls were being sucked, being rimmed with his cock in another womans cunt and licking one cunt while fucking another. The options for mmf were as plentiful, spitroasts, bukkake, being licked and fucked simultaniousy and the big one, double penetration. Yes, Jenny eventualy took Paul's cock up her arse. Solo at first, then with me in her cunt and Paul in her arse and vice versa. Despite Sara's inducements, Jenny refused a lesbian one on one with Sara, even refusing to allow Sara to clean spunk, mine or Paul's, from her freshly fucked cunt. I could understand her reluctance, no power on Earth would persuade me to have any kind of sex with another man, but there was collateral contact. You can't lick the clit of a cunt being fucked without getting balls in your face and passing a cock from mouth to mouth involves an exchange of body fluids, more so than a peck on the lips. In between our foursome weekends Jenny and I returned to what we considered a normal lifestyle. Not so Sara and Paul. They joined a swingers club in a nearby town. They assured us that condoms were the prime directive for members, our relationship need not change. We went with them once, as non-participating guests. It was interesting, but not to our tastes. We did not return. The fact was, I was getting tired of swapping. I had become more and more convinced that Jenny was the one. I wanted her all to myself. Besides, apart from sex, we had little in common with Sara and Paul. We had other interests. I shared my thoughts with Jenny, who surprised me by saying; "I was doing it because it was what you wanted." We decided to end it. I felt guilty, Sara and Paul were nice people with an unusual hobby. Covid came to our rescue, providing the perfect excuse. I also found that eighteen months of 'sharing a cell' with Jenny, we both worked from home so spent all day and every day with each other, was just what both of us wanted. Saved by the bug.
