Title:- Our First Accidental Swing Dave & I have been happyly married for 25years,brought up 3 children,and although we were both virgins when we met and later married,we have learnt the joys of sex together,through times of great frequent sex, to times of little or even no sex at all. Since the last of our children left home for uni,we have tried to spice up our sex life,with more toys, and lingerie etc, and fantasy games where we act out each others fantasy situation,many of them featured sex with another person or couple. I told dave that I would never be able to share our sex life with anyone else,I am quite a shy person really, and lack a little confidence about my appearance,so to our story:- It was a cold day in november and our friend and neighbour cathy called to ask me if I would attend a ann summers type party that saturday, and also help her to prepare everything on the day, I of course accepted,cathy was 10 years younger than me and had nice long auburn hair, unlike me she always took great care of her appearance, and dressed smartly,she was a confident person. Her husband mike was more my age, tall, smart and quite handsome,he worked long hours, mainly to keep cathy in some luxury,I must admit to picturing him making love to me quite often whilst dave and I were having sex. So to the day of the party,we had a great deal of fun unpacking and playing with, many of the disply items delivered that day, dildo's, vibrators,anal plugs,and lingerie,and some slutty costumes too. We chatted for a long while,and told each other all about our sex lives,and I mentioned we we trying to spice up our sex life by fantasy games and new toys, to my surprise cathy said that they had fallen into a routine in bed,same positions,same vibrator,and she wanted to re-ignite the lust they used to have in the early years of their marriage. Cath suggested that we could help each other,and maybe the fantasy of having sex in front of,and with another couple could be a reality,we were so turned on by this talk we both grabbed a vibrator, and we slipped off our knickers,and brought ourselves to a great shuddering orgasm. As the 9 o/clock start approached,I began to be very excited and aroused at the thought of having sex with our neighbours for real!!,I knew dave would be shocked when placed in that position, but as he quite fancied cathy I did not expect him to refuse,anyway,during the party all us girls had a few glasses of wine to break down our sexual inhibitions,and before long we got to know intimate details of each others sex lives,the good,and the bad. At the end of the party cathy and I were putting away some of the sex toys and lingerie passed around during the night,when in walked my dave,and cathy's husband mike after having a few pints at local pub,mike joked that we would not need a man anymore,as the selection of vibrating cocks on the table would make men obsolete,we said nothing could replace a real hard cock,we both winked to each other. Cathy suggested we could watch one of the porn dvd's that were on sale earlier,everybody nodded nervously,she put on an amateur swinger title,closing the curtains,and turning off the lights we all started to watch the movie,a little embarassed at first,but soon it was obvious that we were all getting turned on by it. We were all on their large settee,dave,then me,then cathy,then mike,dave was soon sliding his hand up my jumper and cathy was rubbing the front of mikes trousers(now bulging),soon we were kissing passionatly,cathy asked mike if he minded if she took off her top,he said he didn't,she removed her bra,and exposed her small but firm breasts to us all,dave had a large bulge in his trousers by now,he asked cathy if he could touch them,she nodded,dave looked at me for appoval,I nodded too. I could not contain myself any longer and stripped down to my panties,mike moved in front of me and began to stroke my large breasts excitedly,,mike sugested we could all go up to the bedroom,we held hands as we climbed the stairs,we all stripped off having lost our shyness now,I began to suck on daves hard cock,whilst he put two fingers into my wet pussy,we both kept glancing at cathy & mike,mike was licking cathys pussy expertly,and she was moaning with pleasure,then she let out a scream as her body shuddered to a climax. Dave asked mike to do the same to me next,as cathy offered him a blow job,mike appeared between my legs and began to use his wonderful tongue on my wet pussy,as waves of pleasure travelled through my body I held daves hand,we smiled at each other as we saw the intense pleasure each of us was receiving.Soon I felt an intence wave of pleasure fill me,and had the most exilerating orgasm of my life,I let out a yell,then drifted off into an incredibly relaxed state,dave was now about to come gudging from his heavy breathing,cathy senced this,and stopped the oral sex gently. Swapping around,dave procceded to lick cathys moist love hole with an enthusiasam I had not seen since our first year together. I was longing for dave to fuck me now,I soon had my wish,he took me doggy style,and the thought of mike & cathy watching us was a fantastically exciting experience,soon they were fucking too,(the poor bed),now the moment of truth,cathy asked if we could now swap partners,dave looked at me grinning like a cat finding a bowl of cream,I said try and stop us!!,mike laid me on the edge of the bed,and pushed his lovely cock very slowly into my love tunnel,I gasped as he slid it in as far as it would go,it was a similar size to daves cock,but it felt totally different,I wrapped my legs around his waist and used then to push him deeper into me. I glanced at dave,cathy was on top of him and riding him for all she was worth,as he was holding her firm tit's in his hands,I don't know which of us moaned and panted the most,but soon mike whispered to me he was about to come,I told him he could come inside me as I was on the pill,his face lit up,and then his body stiffened and I felt a gush of his hot come squirt deep into my pussy. Mike layed ontop of me for a while,and I could see dave was also about to come,cathy asked him to come into her mouth,he nealt up infront of her and she slid her mouth rapidly up and down his cock,dave held her head as his hot semen filled her mouth,she then swallowed every last drop. Dave and I cuddled each other as we lay recovering from the marathon sex session,mike and cathy did the same,we all agreed it was the best nights sex we ever had,but it wasnot over yet,after a rest we all continued till almost dawn.
