I have been with my girlfriend Jane for 10 years; we have a great sex life and have also done a few threesomes mostly with women, as she is very bi curious. I find it a big turn on to watch her with other women. But we have never taken it any further than the threesome that was until a couple of months ago. We have always fantasised about having a group session and some of our best sex has been whilst watching our favourite porn video. We are both mid 40’s Jane a size 14 with great bust with brown short hair. I am fit and muscular with short-cropped hair I work out 4 times a week. So how do we start? Jane knew a girl at work who had an open relationship with her husband so was very interested in asking how it works and how she gets her sex. She suggested that we come over to their house on sat night and that she will have a “virgin” swingers party. Part of me was so excited at the thought the other half of me was terrified of it in case it would not come up to the expectations of the porn we have watched over the years. As Jane had been doing all the negotiations about or first party with her work colleague I was left out of the loop, I did not know if this was a good thing or a bad thing. I did not know all the details of the party all Jane told me was that we were going around to Chris and Sue’s house on Saturday night, getting changed before we went was a weird event, what do you wear at a sex party? Sue told me she had been shopping and got out a black bra and knickers set and me a new pair of blue tight Ausibums, which really made my cock look large. We had been told to dress casual so Jane had a thin summer dress and I had shorts and a shirt, I love wearing shorts as I have very muscular legs and shorts show them off well. When we drove to Chris and sues house we were very excited I had a semi all the way with Jane grabbing my hand and plunged it between her legs for me to feel here damp pussy, this was going to be a great party. At the door Chris met us, he showed us into the front room to meet the other guests. Chris introduced us a virgin partygoers and how everyone should make sure we have a good time. Chris and sue were in their late 20’s both good looking and sue was a stunner, straight away when I saw her I was hoping that I will get to fuck her first. The other couple were john and Amanda who were about our age, me and john hit it off right away as he was a body builder with a fantastic body, the sort of look I want to get to look like. So we did not feel pressurised the hosts explained that for the first half hour or so we would all strip to our underwear and chat and make small talk. I could not take my eyes off sue as she stripped down. All the women were in two piece bra and knickers all looking great, it was hard for me to stand without getting a boner in my pants, this was not un-noticed by Amanda who gave it a lingering look and wink. So we are standing around all in underwear chatting away as if we were at a housewarming party… the wine was flowing and I was getting more settled about being semi naked. The other two couples told us they had all known each other for a few years having first met at a mixed sauna. I was watching Jane chatting to John, I was unable to see what they were talking to but she was stroking his muscled chest, this was turning my on big time and again I was fighting my cock trying not to get hard and be spotted. I decided to go to the kitchen to refill some glasses to take my mind off it. Amanda came into the kitchen to give me a hand. As soon as we were topping up the glasses she looked down at my semi and the slight damp patch on my Ausibums. All my like I have been able to produce loads of pre cum and regularly make damp patched on my jeans when Jane turns me on in a bar…. Amanda reached down to glide her finger over the damp patch and then put it to her lips, by now my hard on was full blown. Amanda told me to come back into the main room and announced to the crowd that I had a hard on. The trunks were very tight and I have a good size cock, then the discussion started as to if I was cut or uncut as it was hard to see. John who was now standing behind Jane with his arms wrapped around her waist suggested that the girls guess and the one who gets it write would be the first to be fucked by it. My cock was bursting and had made a very noticeable wet patch against the blue trunks. Sue said I was uncut and Amanda said I was cut. I told sue she was right and she walked over to me went down on her knees and started to lick my cock through my trunks lapping up the pre cum…. I looked around and all the girls had lost their bra’s my wife was snogging John and he was groping her ample breasts. Sue was sucking Chris’s cock. With in a few minutes sue had come over to me and Amanda and Chris had gone over to Jane and John. I was told to lie on the carpet and Amanda sat on my face facing sue who was sucking on my cock. I was in heaven Amanda had a shaven pussy and I knew I would be making he cum, she was grinding her pussy against my chin as I was liking between here pussy and ass. Jane and I had learned the fun of rimming years ago and I started to give Amanda a good rimm using my stubble on my chin to massage her pussy, she was squealing as she came… Looking over I was watching my girlfriend being spit roasted by the muscle man john and Chris. John was fucking her raw, this was a big turn on for me knowing that she would be seeded by a cock which was not mine. Jane was on all fours being fucked from behind and sucking Chris’s cock as Chris sat on the sofa. Jane is a dirty fucker and was loving the attention. The sight was too much for me to take as sue and Amanda were now both sucking my cock and sharing it between their tongues. I shouted out that I was about to come and they lapped up every drop of spunk then shared their spoils with a passionate kiss whilst being watched by the rest of us. It was not long before john and Chris came almost at the same time. It’s hard to explain what a big turn on it is to watch your girlfriend be serviced by a big muscle man and watch him cum up her pussy whilst she is drinking the cum from another guy. We chatted and drank some more, it was not long before we started again the rest of the night was spend with us all fucking each others partners and also watching the three women put on a lesbian show for us. We stayed the night and the party broke up about 2.00am with the women having a talk to decide which man they would take to the bedroom. Sue took me to the main bedroom john and Amanda and Chris and Jane to the other. Sue and I did not get much sleep she got out her toy collection. In the morning we all had a good grope and snog session over breakfast and we arranged to meet again. But that’s for another time to tell you….
