If you have been following Kevin and my stories (Trim the bush Pt 1 & 2 and parts 1-3 of this title) your recall that we had just had our first swap session with the Browns, the widow and another guy. Round 1 of the evening had been really dull but round 2 had been more fun for both Kevin and me. We had chatted about things on the way home without going into too much detail, that was being saved for our next session in bed. Kevin walked Sally who had been child minding back home around the block and by the time he returned I was in bed.

The next night I got to hear from Kevin how Mrs Brown and widow had not only kept him busy but also how they had played together, that had been a real turn on for him and the first time he had seen two women together like that. For my part I told him that Mr Brown and the 50 year old had given me a spit roast and a Dp as I had asked for. In bed we had another GREAT session between us and it was a good job I had to wash the sheets next day because they were needing it. One evening during the week we get another phone call from Mr Brown but with the kids still around we ring back later in the evening. Gist of it was that if we were up for it we were welcome back to theirs and now that knew what we enjoyed they would ensure the right people would be there, Kevin and I agreed we would enjoy that and Brown said he would let us know. For the next 18 months we were regular visitors to the Browns, normally once a month together and later on I would be collected once a month while Kevin looked after the kids and then he would go over the following weekend while I ooked after the kids.

The Browns were as good as their word and that second visit went much smoother, 2 other couples and we all played in the lounge, first time I had seen kevin actually fucking other woment and of course first time for him to see me being used. That night we had another GREAT session together, clearly to see each other fucking others was a big turn on for us both. As things developed the action got more steamy, sometimes I would go upstairs with two or more men, sometimes Kevin would do the same with two or three women, other times the men would rotate around the bedrooms while the ladies made themselves available, at some of the larger gatherings it might be more than one lady on the bed while four or more men used any vacant hole. It all depended who was there that night, some of the women would dress to impress, nice outfits which ended up with large damp patches. It was at one of those evenings that Kevin was handed a telephone number by George who was there with his wife Liz, all done on the QT so that the others did not know. George was always a leading light, a bit bossy at least every time I was with him and Kevin said that Liz liked to be used and taken full advantage of.

So on the Sunday evening after the Brown`s party Kevin rang the number, liz answered and quickly put George on the phone. They were having their own party that weekend and we were invited. George explained that it would be a smaller affair but that it might be more interesting, asking if I would be up for a bit of bondage and slap and tickle as he put it. Kevin said he would ask me and get back to them whcih he did the next night. Saturday night and we turn up at George and Liz`s place (thank you mummy for baby sitting again). We go in and the lounge is already in half darkeness, upstairs clearly some movement and sounds of someone getting a slap. Liz is nowhere to be seen so I assume its her getting some treatment. George returns with drinks and once his hands are free grabs my tits for a feel, telling us to strip off as soon as we can and join the fun.

If you have ever been to somewhere new for something that you have never done before your`ll know you get that "have we done the right thing moment---how soon can we leave". Oh well in for a penny in for a pound and Kevin is already down to his Y fronts and about to loose those, another sip of the vodka and I strip off too finding somewhere on the floor at the far wall to deposit our clothes. Upstairs we go followed by George, and into what I guess is the second bedroom. Liz has just been getting her backside slapped by another womand while two men look on. Then this other woman is laid over a chest and has her backside slapped by one of the guys, Liz is having her nipples pulled by the other guy and George his hand now between my legs is asking if I am OK with things. What can you say, it was our first time at this kind of thing, it looked interesting but I was not too sure about having my bum slapped. George assured me that he would be gentle with me and told me that they used a safe word "red" if I wanted to stop. Kevin was not much help, he was too engrossed with the way Liz`s tits were being pulled by the nipples. George sat on the edge of the bed and I was over his knee having my bum slapped, let me be clear he was a good as his word the first strokes were a very light touch and got harder. Each time he would check with me that it was OK, rub my bum cheeks and administer another heavier slap, eventually I said he should stop and he reminded me that only the safe word should be used, slapped me lightly on the bum, I said "red" and I was allowed to get off his knee. Kevin had now joined the other bloke and Liz and was yanking on her nipples while the other bloke was rubbing her cunt, she was enjoying it!

Things moved along, dildo were produced and put into various holes, then the other woman and I were taken into the main bedroom and told to play with each other while George, Kevin and the womans husband watched, Liz stayed in the second bedroom being used by the single guy. That was my introduction to Bi sex, I must admit I enjoyed it, I didnt need to adjust my position or tell the woman what to do, she instictively knew where to find my pleasure zones and soon I was in the moment and starting to orgasm. I`m not sure I was doing much for he but I did lick her as she had done to me, she seemed content with my effort but clearly I had a lot to learn. Then the three men climbed on us and our holes were used. I thought that would be the end of things but Liz had obviously been finished some time went downstairs and by the time I got there some snacks and drinks were on the dining table.

Round two of the vening was still to happen, but you need to wait until my next posting for that
