This story is a little long, but better than splitting in to parts. It goes back a while when my then girlfriend, now my wife, and I used to play quite often. Jenny is lovely, and when we were in our thirties used to love the foursome/moresome evenings. We didn't used to play every week, just when the mood took us. We were at an evening social hosted by friends Paul and Joanne, a lovely couple who we did always imagine playing with - but it was no more than pillow talk. also at the evening were two other couples we had never met before. Gerald and Marjorie were a little older than the rest of us, nice company but came across as a little aloof. Steve and Sue made up the gathering. As the night progressed and the wine flowed a little the talk became a little easier and as happens turned to summer holidays and the inevitable sun, sand sea and sex. Steve and Sue were talking about their holiday and wandering by a nudist beach that had far more than just nudism on offer and their shock at the sights. Gerald and Marjorie tutted at the thought of such open sex, Paul and Joanne, Jenny and myself just listened. Out of the blue Joanne suggested that, as the youngest couple there, Jenny and myself probably found the idea to our liking and may well enjoy that sort of thing. all the attention fell on us, and jenny spoke first saying we too had met such scenes and did actually spend time watching - using it as foreplay for ourselves. I nodded as Jenny continued to give s few details of the activities we had seen. I did wonder if the party was now about to come to an abrupt end, but was surprised to find that even Gerald and MArjorie wanted to know more. The wine continued to flow and Jenny added more detail, from the shuffling on the seats and the discreet tugs on clothing it was obvious the others were more than just intrigued. It was Joanne who once again kept things moving when Jenny paused, asking if we had ever been part of such activities ourselves. Without batting an eyelid Jenny replied "Not on the beach, but we have been to parties where the themes have been adult and sex involved". Now the room did go quiet, and shortly after Steve and Sue made their excuses and left. Gerald and Marjorie remained quiet and attentive as Joanne wanted to know more and Jenny was keen to supply the detail. By now I was incredibly horny, and could see that Gerald was also looking aroused, Paul could not hide the bulge in his trousers. Although not planned or imagined I thought that the night was far from over! A few more tales and a drink and the party atmosphere subsided, and it looked like it was time to go. We asked if we could phone for a taxi, and when Gerald asked where we lived we discovered it was close to them and we shared the ride. We were asked in for a coffee and agreed to join them. As soon as we were indoors the thoughts of Marjorie and Gerald being aloof were soon dispelled. It was perfectly obvious why we were invited in, they wanted to know more! Marjorie was keen to know how the parties Jenny had described gathered pace and ended in sex. Jenny, with a captive and interested audience, did nt hold back and covered all angles. After about half an hour Gerald reminded Marjorie about the coffee and I offered to help. It was clear Marjorie was turned on, she was no longer calm but all of a fluster. I gave her a cuddle and a reassuring peck on the cheek. She smiled and said "You know how I'm feeling don't you?" I replied "Yes" and she said "The thought of wearing almost nothing to a party is erotic. I can't imagine how you men can keep your hands off women who you know are braless and probably knickerless. I've never done that" I decided to push things along and gave her another kiss, more passionate this time, and slipped my hands behind her and undid her bra. "try it" I suggested and moved the strap down her arm, and removed the bar from under her blouse. I had no resistance, and the erect nipples told their own story. I put my finger to her lips and suggested she say nothing, just go with the flow. We returned with the coffee to find Jenny and Gerald enjoying each others company, Gerldd talking more to Jenny's chest than making eye contact as they sat on the settee. I sat in one of the arm chairs and without prompting Marjorie sat on my lap. I rested my hand on her leg and gently stroked it through her trousers. Jenny was animated, telling me that Gerald and Marjorie had been interested in, but not gone to, a live show when they visited Amsterdam. The conversation was becoming more intimate with Both Jenny and myself telling them how much of a turn on we found those situations and how it increased our sex drive, particularly in a party where we knew the people and were likely to be watched ourselves as well as joining in. My hand had now reached the top of Marjories thigh, hidden behind the arm of the chair. No resistance and from the warmth and dampness I could tell she was really turned on. I suggested another coffee which was readily agreed and offered to help again. Jenny made an excuse to go to the loo, as we left Gerald in the room Jenny caught my eye and indicated that she too was going to remove her bra. She mouthed at me to take my time. I joined Marjorie in the Kitchen and we talked quietly. When I asked how she now felt she moved forward and kissed me before saying "I want sex, and I don't care if it's you or Gerald" We kissed again and I undid a couple of her blouse buttons, and gently teased her nipples through the material as she closed her eyes and threw her head back. I desperately wanted to explore more of her, but trousers are not as good as skirts in this respect and I would have to wait a little longer. We had heard Jenny return, I stalled for a while but we then took the coffee back. Jenny was now much closer to Gerald and had duly removed her bra, and also loosened some of her blouse buttons. She had Geralds total attention! Not content with that she turned to Marjorie and asked if what she had done was Ok. Marjorie just nodded and undid one more of her own buttons. My hand was now back between Marjories legs, and the heat and wetness were more intense. Jenny was now totally up for it, and I could tell she needed sex. In this mood she can move things on quickly and usually without offending anyone - she has the nack of reading these situations very well. Picking up on our earlier conversation of live sex shows, Jenny asked quite politely if Gerald and Marjorie would like to see a live show. They both agreed it would be good but were unsure how to go about it. Jenny stood up and slowly undid another button on her blouse, facing Gerald but back to Marjorie and myself. "How about getting rid of that problem and having a live show now" she asked. Nothing was said, so Jenny undid the rest of the buttons on her blouse exposing her lovely breasts to Gerald, She let the blouse fall to the floor, and topless turned to Marjorie and said she needed to borrow me. Jenny took my hand and I stood up and gently caressed and kissed her breasts, sucking on he erect nipples. We then slowly undressed, now both naked and kissing and touching in front of Gerald and Marjorie. Jenny moved her mouth to me ear and pretended to kiss it, but whispered "lets get them naked" As she moved back she gently but firmly said "No clothes in a show like this" and moved towards Gerald as I took Marjorie by the hand and helped her off the chair. Marjories blouse took no time to remove, revealing a lovely pair of breast with firm nipples, which received the same attention as I had given Jenny. Although a little difficult the trousers were soon off, leaving just a pair of delicate lace panties to remove. I slipped my hand downward, and using my other hand guided Marjorie to my erection which was now soaked in pre-cum. She did not need a second invite and slowly stroked the erection. As my hand went inside her panties I discovered she was 'natural', not shaved like Jenny. As my fingers moved around and teased her lips I easily slipped in to her wonderfully wet and warm pussy. Nothing was being said, the sexual atmosphere was electric. Jenny eventually took the initiative again "Who do you want to watch Gerald? Phil and me or Phil and Marjorie" Marjorie replied for him "Let him watch" was all she said as she moved me to the floor on the sheepskin rug. As she lay on her back she opened her legs and I slid in effortlessly, a couple of strokes and Marjorie came loudly and strongly. I carried on rhythmically and as I came so did Marjorie for a second time. We lay there for a moment before looking t Jenny, who was bobbing her head on Geralds erection. "Our turn to watch " was all Marjorie said as we stood up and changed positions. In all fairness we did not do too much watching as Marjorie was giving me a very good blow job and bringing me back to life. Gerald was a good stayer and was going for ages. I took Marjorie by the hand and we joined them on the floor, all four of us now moving rhythmically to orgasm. We had sex with Marjorie once more before Jenny reminded them that we did offer a show. She explained this was no longer sex, but love making between us as a couple. I lay on my back so Gerald and Marjorie could get the bets view as Jenny eased herself down and started riding me. It was hot and steamy as usual after a swap session, when we looked over Marjorie and Gerald had also started their love making. Naked and exhausted we all sat on the floor talking, before eventually getting some sleep. Marjorie brought us tea in the morning, I took her hand and she bent forward to give me a kiss. Jenny stood up and informed us she would check on Gerald. Marjorie joined me in bed and we had sex once more. Once downstairs and dressed the door bell rang. Marjorie answered and ushered Paul and Joanne in. They were speechless. " I suppose . . . ." was all Joanne could say Marjorie spoke "Yes, you suppose right. We carried on the party, and yes we did have sex together." Still no word from Joanne. After a coffee she did say "And what happens now?" Marjorie looked her in the eye "My parties are likely to be a little different from now on. I was thinking of next Saturday. Do you and Paul want to come" Jenny giggled at the unfortunate phrase used "If you turn up for the party I can guarantee you'll come" was her response, everyone laughed apart from Joanne. When she did eventually speak it was quite short "what time next Saturday?" If yu liked this I'll give the party details later
