My partner Jane and I had for a while recently discussed having another playmate in our bed. For a while when at our highest erotic moments I would say to her whilst rubbing her pussy that another guy is behind her and is rubbing his thick cock against her arse wanting to penetrate her. I would then move behind her to do spoons and pretend to be that other guy. Jane would go wild and would quickly orgasm by wanking herself, and as I entered her from behind. I would keep screwing her, pushing her back from me to slap my hips hard against her bottom and my balls slapping the top of her thighs. I would continue to narrate that I was another guy with a big cock fucking her, and Jane would just ask me to fuck her harder. Once I had cum, and I had turned onto my back, Jane would move down on me and suck my cock clean of any sperm and wank me to full erection again. As she did so she asked me if I really wanted her to shag another guy. I thought about it briefly, not being quite as horny as I was a few moments before, but braved to say Yes. I told her I wanted her to get between my legs and suck my cock whilst she is being screwed by another man who has a long, thick penis. When? she asked. When she is ready, I said. I\'m ready now she said. We made love again before falling asleep, but in the morning it was our sole topic of conversation. How would we do it, who could we get? Jane is 42, 5\' 6\", blond, very slim with size 32A tits, and a great arse and pussy mound. I am the same age, 6\' 1\", athletic build, but I only have a 6 inch cock. I please Jane with my cock and mouth, but the more I read on Swinging heaven, the more I wanted Jane to have a big dick inside her. We posted our profiles on the site, and got some nice replies from a few guys in their 30\'s, and claiming to have 9\" or more. However Jane got cold feet in this direction, but her enthusiasm rekindled when we went out to the pub at the weekend. We got talking to a nice couple, Sandra and John, both were in their late 30\'s and dressed very well. Sandra\'s tits were especially pleasing to the eye, though Jane was not being outdone having pushed hers up with a lovely black bra. John was very attentive to Jane, he was clearly interested and did not hold back the complements to both women. We were having a nice time, and Jane was clearly enjoying the additional attention. The drinks flowed, and we decided all 4 of us to go to a bar with a dance floor. John and I got the drinks up, whilst holding the girl\'s coats as they had gone for a \"Bop\". As the night wore on I was spending more time with Sandra, and John with Jane. Sandra was very tactile and would stroke her hand down from my shoulder to my chest, flicking the nipple which would become erect. I noticed at one point Jane touching John\'s bottom as she moved closer to hear him say something above the sound of the music. Jane was clearly enjoying herself. I hadn\'t seen her laugh so much for a long time. We were all getting on great, as if we had known each other for years, and when the slower numbers started I whisked Jane up to the dance floor to have a wee chat. We agreed that they were a nice couple, but if the chance arose could she sleep with John? Could I sleep with Sandra more like, suggested Jane, but I reminded her of what it could be like to have 2 cocks inside her. Jane smiled and said we would see. John danced with Jane, and I with Sandra. Her sexy red dress and large tits gave me a hard-on when I pressed myself against her. Sandra was game enough to let on she could feel my cock against her tummy, and was pleased I found her attractive. On the track finishing I turned in time to see John kiss Jane on the neck, and Jane smiling broadly. We agreed to get a taxi back to John and Sandra\'s for some more drinks, and not to let the evening end so early. They live in a nice modern 2 bedroomed flat in the South-side, only a few miles from our own home. The lounge had a hardwood floor, with only a small rug next to the large fireplace. 2 stylish settees sat at right angles to each other, and a large coffee table made from re-claimed railway sleepers looked after our drinks as we chatted. Sandra sat with me whilst Jane had moved to be besides John. Our chat soon got down to the inevitable, sex. John said that both he and Sandra had videoed themselves fucking several times, and even uploaded some of it onto the internet. They were very pleased with the outcome, and would often watch it in between their love-making. Jane dared John to show some of it. Darling, said John, is it okay. Sandra smiled in the affirmative. John inserted a DVD into the player, and quickly images of Sandra stripping appeared on the 42\" Plasma. We were no more than 10 feet away from the screen when I saw Sandra unclip her bra and play with her 36C tits. Not thinking I said ‘Great Tits’ out loud. Sandra laughed and placed her hand on my inner thigh. On view John comes into shot wearing just his boxers. He looks very fit and athletic. He touches and feels Sandras tits before sucking on her large nipples, taking each in turn, sucking hard before releasing each with a smack. Sandra kisses John before dropping to her knees and releasing his cock from his shorts. Even semi-rigid it looked big, and Jane just gave out an Oooohh! when Sandra puts him in her mouth. Jane then gets up from the sofa and moves closer to the TV to get a better view. Without warning Jane admits our fantasy, of her getting fucked by me and a guy with a large cock. Jane looks at Sandra, and Sandra admits that both she and John have discussed sharing. Sandra was all the while stroking my thigh, that coupled with the video, I was rock hard. The camera angle changes, and next we see John down lapping at Sandra\'s pussy. It is shaven and gloriously red and swollen, as he dips his tongue in her hole and nuzzles her large clit. Next we see the camera from above as John takes Sandra from behind. His large cock is slowly sliding in and out of her cunt, and he playfully removes it once or twice to spank her botty with his dick. By now Sandra is stroking my cock. Jane turns to see this and approaches us. She kneels down and unbuttons my shirt. Sandra pulls my zipper down and unclips my belt. I kick off my shoes, and immediately I am stripped of my trousers and pants. Jane takes my hard cock in her right hand and wanks me into her wide opened mouth. Sandra scratches my balls before joining Jane to suck me hard. John meanwhile has stripped and gotten behind Jane, lifting her dress from behind, and stroking her pussy from underneath. Jane stands up pulls off her dress and G-string, leaving just her black bra on. She returns to my cock, but pushes her naked bum in the air to allow John to enter her from behind. Fuck! Is Jane\'s first words as his large cock enters her and slowly rides her for the first time. Her head falls onto my thighs as John starts to pound her harder, pushing deeper with each thrust. Sandra takes over at my cock, and Jane asks me if this is what I wanted? Fuck Yes, I replied. Sandra gets undressed, and whilst doing so John leads Jane into the Master bedroom. I stand up assisting Sandra to remove her bra and knickers, before holding her closly, feeling her lovely large melons, and fingering her wet cunt. We kiss deeply and with our tongues. We join John and Jane in the room. Jane is sucking John\'s big prick, and I lay Sandra down beside them before going down on her juicy bald fanny. I put her legs over my shoulders, allowing me to thrust my tongue in deep. I spit on her cunt and then in a tried and tested manner give her clit a lot of friction with my tongue and chin, making her cum noisily and dribbling a little pee at the same time. John seeing this gets on top of Jane, whose legs are wide apart, and he thrusts very hard into her. His cock is so thick that Jane\'s fanny lips are moving in and out of her along with John\'s dick. I turn Sandra around and start fucking her from behind, as I do I am looking into Jane\'s eyes and she is still smiling. Her neck and chest are red with lust, and she cries that she is cumming. I hold onto Sandra\'s swinging tits and fuck her harder. From underneath she rubs my balls, she tells me to cum inside her, and within a few seconds I squirt my seed deep into her. John likewise follows suit, and with a yell he cums inside Jane. Pulling out of her briefly he still jets his sperm over her belly and tits before putting it back inside Jane’s throbbing pussy to fully empty himself. I lie beside Jane and we kiss and cuddle. John does likewise with Sandra, and lying close together I drop off for a few moments. I wake to find both girls sucking on John who is already hard again. He lies flat on his back and Sandra straddles him. Once he has entered her she starts riding him. Jane is stroking John\'s chest and biting at his nipples. With Jane\'s bum in the air I enter her from behind and we fuck together until John, Sandra, and me cum. Jane not having cum stands over John, wanking herself, sperm dripping from her thighs, Sandra stroking Jane\'s bum, until Jane cums in a rush. We all slept in that same large bed overnight. In the morning dressed in only robes we sat on the sofas having breakfast. John\'s robe fell open showing his massive dick, and Jane just had to have one more fuck from him. He lay her on the rug at the fire before entering her. Sandra was playing with her nipples, and so I helped her, chewing on them, whilst fingering and rubbing her cunt until she came. As John was cumming, Jane had already came a couple of times, he pulled out and sprayed Jane full on the face and neck. Sandra went over to them and licked John\'s cum from Jane\'s body. I stood between them both and after a short wank spunked over both their faces, Jane sucking me dry. Shortly after we showered and called a cab. When we got home Jane and I went straight to bed. She had me fuck her arse as her pussy was a little sore. A few days later we have spoken again to John and Sandra, and we have agreed to do some videoing of the 4 of us having some kinky fun. Jane agrees that having more than one cock to fuck is more satisfying physically, but is wary that it could affect our relationship in the long term. For me, having been married twice, and lived with several other girls, I could not imagine fucking just the same woman for the rest of my life. We are both young and fit enough to enjoy lots of sex with other people, and for those of you undecided, take the chance especially if it happens by accident, like our first time.
