I'm Dave and this is the third time I've written about some of the adventures I've had with my wife Kate over the years. These are all completely true, apart from the names.

The first two were:

Kate's First MMF - tells of the first time Kate had two cocks all to herself

The Long Road to Swinging - tells of our sexual background, and how Kate's cheating was the spark that turned us into swingers

This time, I'll tell you about our first actual experience of involving another. This was before we were married, but we'd been together for ten years and were engaged.

Kate and I both worked for a large employer up here, in different departments. We didn't really see much of each other throughout the day at work. I had started to notice a new girl in yet another department, who reminded me slightly of Kate. She was about the same height, a little over 5 ft and also with long dark hair. I would later learn that she was 26, the same age as Kate. I'd see her in the canteen, or walking between buildings some times. There was just something about her, she was captivating. I really wanted to get to know her, so when I had an opportunity to go to her office as part of my job I jumped at the chance. Up close, she was amazing. Not only was she beautiful but even though she was dressed quite conservatively for work she still managed to radiate pure sexual energy. After I'd finished what I was there to do, I hung about and we chatted. Her name was Ruth, and she'd not long moved to the area for this job. I really liked her, not only for her strange highly sexual presence but she was extremely funny and highly intelligent - two of the things I've always liked in a woman. Over the following weeks, we started to bond in a strong but platonic friendship. She lived with her boyfriend Simon. Our friendship deepened and we became extremely close, and we started to talk more about our sex lives. She'd not been with her boyfriend long, just a month or so before moving here and was in the process of divorcing her husband from whom she was separated. She told me that when she lived in the south, she and her husband had been very active on the swinging scene. She was very bi and was so into women she was almost gay at that point in her life. She had an astonishing amount and variety of sexual experience and was very open to discussing it. She knew that I was hoping to start swinging with Kate, and her advice was readily given and very welcome. Kate had still never met Ruth, although if I'm honest she was probably tiring of hearing about her, and we'd never met Simon so we invited them both to our house for dinner one Saturday night. I'm not sure what Kate was expecting, maybe she thought Ruth would be just another weird friend of mine or that she was somebody I wanted to fuck. I'd always reassured Kate that there was absolutely nothing going on, that we were just good friends so I hoped (and thought) she trusted me on that. She was keen to finally meet this Ruth, anyway.

We finally got to the weekend, and for our Saturday night guests we slightly dressed up. I wore smart casual type stuff, good jeans with a nice shirt, and Kate put on a nice black dress. At around 19:00, the doorbell rang and I opened the door to let Ruth and Simon in. We all sat in the living room, each next to their own partner, and through small talk and chat started the process of all getting to know each other. To my relief, everybody got on really well. Simon seemed a good sort, and Kate and Ruth were soon chatting away like old friends. They had dressed up a bit too - Simon like me in a smart casual style, but Ruth.... well, she was stunning. She wore a thin white dress through which you could make out her bra and thong (if you looked hard enough, and believe me everybody did), she was displaying a decent amount of cleavage, her hair was tied up and she wore bright crimson lipstick. One of the things she'd told me about herself was that she'd helped fund her way through university with some modelling work, which included some topless posing. We sat chatting and laughing for a while, and although Simon was driving them home later Ruth, Karen and I were all drinking. I then realised that I should probably go and make the dinner, a very nice curry that I'd made before and which only took about 40 mins. So I got up and headed to the kitchen to get started. While I was busy chopping, Kate came in with her and Ruth's empty glasses to refill with gin & tonic. I asked her what she made of Simon and Ruth, and he said that he seemed nice. Kate then surprised (and really pleased) me by saying that Ruth was "extremely sexy". There was no swinging that night, we ate, we talked, most of us drank and they left. However, everybody got on very well, and I knew that Kate not only liked Ruth as a friend but might perhaps be interested in finally experiencing another woman. Again, this was something that we talked about in our dirty talking times, but you never really know where the fuzzy line between fantasy and reality is drawn.

On Monday morning, I picked up Ruth and we drove to work together - something we did pretty regularly. By this point, Kate had lost her job at the place we'd all worked at and had just picked up a part-time one elsewhere. I asked her how she thought Saturday night went and she said great. She said she really liked Kate, and that she was "absolutely gorgeous". My cock almost lept out of my trousers when she added matter-of-factly "I'd love to shag her". I told her what Kate had said about her to me in the kitchen, and that she'd had lesbian fantasies and talked about being with a woman, but added that I wasn't sure she'd actually go through with it if push came to shove. Ruth asked if I'd be ok with it, and I confirmed I'd be absolutely delighted with it! "Well then", she said, "we'll see". That evening, Ruth phoned to invite us round to their house for dinner on Saturday and to stay the night so we could all drink, and we accepted.

I didn't know what Ruth had in mind, was she going to make a move on Kate? I didn't think so, that it was mostly or all talk, but through the week Kate and I were talking about these lesbian fantasies of hers - I was keen for them to be on her mind and thought about as we approached the weekend. I didn't say what Ruth had told me she'd love to do, as I didn't want Kate to feel she was being set up or ambushed. I did, though, say that if she wanted to experiment with another woman then Ruth offered as good an opportunity as she'd probably ever get. She found Ruth very attractive, I said that Ruth had called her gorgeous too. Ruth was highly experienced with other women, so there'd be no awkward fumbling or embarrassment from her, she knew exactly what to do and I had absolutely no doubt she'd be extremely good at it. There could be no better way to be introduced to being intimate with a woman. Kate agreed, but when asked if she'd like to try it with Ruth her answers went from "I don't know" through the week to actually just "no" while we were driving there on Saturday night. This was disappointing obviously, but there was no rush and I didn't want to pressure her.

We were all just casually dressed this time. Jeans and a t-shirt for me, Kate was wearing jeans and a blouse, no bra and a thong. When we arrived, Ruth let us in. She was dressed simply too, in black trousers and a blouse. Simon, she said, was at work and wouldn't be home until after 22:00 and we'd be eating then. With almost three hours to go before then, the three of us picked up where we left off the previous Saturday, chatting and drinking. There was no sexual tension at all, surprisingly, and it just felt like three friends spending time together. Once we were about three drinks in and our glasses were empty, Ruth turned to me and said "why don't you get us all more drinks?". So I picked up the glasses and headed to the kitchen, quite a bit away from the living room we were in. When I got back with the drinks, Ruth and Kate were standing in the middle of the room kissing passionately, Kate's hands on Ruth's waist and Ruth tenderly holding Kate's face. I actually laughed as I put the drinks down, as I thought they were having a laugh and teasing me. Without stopping the kiss, Ruth lowered her hands and placed them on Kate's clothed breasts and started to gently knead and feel them. It was about now that I realised that they weren't having a laugh, and when Kate recpirocated by cupping and feeling Ruth's breasts I knew she'd made her decision about experimenting. Their lips parted and Ruth started to unbutton Kate's blouse. Kate asked "shall we go upstairs?", but Ruth said no because Simon would notice the state of the bed, they'd have to stay in the living room. This disappointed Kate and for a few seconds it looked like nothing would happen, so I said that if my being there was making her self-conscious or uncomfortable I could go to the room next door. Kate said thanks, and that I should do that if I didn't mind. So I picked up my drink and went in to the other room, while the girls continued to unbutton each other's blouses. I left the room and closed the door behind me. I fired up Ruth's computer to pass the time messaging friends and watching porn, although there could be nothing I found that would more exciting than what was happening just a couple of dozen feet away, even if I couldn't see it. I could hear, though. I heard Ruth and Kate giggling, and talking softly. I kept taking sips of my drink while at the computer. After about 15 minutes, I realised that I couldn't hear them any more, that they'd stopped giggling and talking. This, I assumed, meant that Kate was finally enjoying the attention of another woman, that she was being expertly pleasured by Ruth. It wasn't long before I heard confirmation of that, with a long drawn out "oh" from Kate. I could hear her gasping, moaning and sometimes saying "oh yes". I could tell her orgasm wasn't far away, and with some almost shrieking moans it arrived. It sounded like a very good one, exactly the kind I'd have expected Ruth to give her. Had she used her hands? Her tongue? Some toys? I had no idea. The talking and giggling resumed, and there was a loud laugh from Kate who I would imagine was extremely nervous. Before long, it was the same again - talking was replaced by silence, which was replaced by the sounds of Kate in sexual rapture and then of her cumming again. By then I'd finished my drink, and really needed another one! The house was an old one, with all of the rooms in a line, so in order to get to the kitchen I'd have to go past Ruth and Kate. Since it was another period of soft talking, I assumed they were relaxing. I picked up my glass, and with that and an aching hard cock I knocked on the door and asked if it was ok to come through, to get to the kitchen for a drink. Both girls said yes, so I opened the door and went in. I couldn't believe the sight that greeted me. Kate was half sitting and half lying on the floor, with the top of her back leaning against the front of the sofa and her legs stretched out and open in front of her. Her blouse was still on but open, and her tits were on display. She was naked from the waist down. Ruth was lying at full length on the floor. She was topless, although I couldn't see her tits and she still had her trousers on. The thing I liked best though was that she had her face between Kate's legs and was using her tongue to gently lap at her pussy, and Kate was moaning quietly. Ruth didn't even look up when I passed, but Kate made eye contact with me. "I told you she'd be good" I said, and Ruth laughed. Kate just said "god, she really is". Although Kate had cheated in the past, at least to the extent of oral, this was the first time I'd actually seen her with anybody else. I asked if anybody else wanted a drink, to be told they had all they needed, so I went to the kitchen and made myself one. When I came back, they'd moved. Ruth was now naked and was sitting back in a big armchair with her legs draped over the armrests. Kate was kneeling on the carpet in front of her, and was exploring her pussy - the first she'd touched except her own. I didn't hang about as I didn't want to put them off, so I walked back through to the other room with my drink. This time it was Ruth that I heard being pleasured. She sounded different to Kate, a bit more vocal and lounder. It sounded like Kate was doing a reasonable job of it, as after 10 or so minutes I heard Ruth cumming. Again, there was more talking followed by more noises of sexual pleasure, but they suddenly stopped and I could hear them talking again. Then, loudly, I heard "Dave?". I replied "yes?" and then heard Kate say "you can come in if you want". Although I thought this meant they'd probably finished, I wasted no time joining them in the living room. They hadn't finished. Kate was now naked and lying on the floor, with her head towards me. Ruth was on top of her, in a 69 position. Ruth lifted her head and turned to me, saying I'd already seen them together anyway, so there was no point in staying through there. I sat in the armchair Ruth had been on earlier, and watched them in fascination (and still with a rock hard cock). I chose that chair because it was exactly lined up with them, giving me a great view of Ruth's pussy while Kate played with it. She stroked and licked her clit, and sometimes put as many as three fingers in her. Ruth had been training her well, although sometimes she just lay back moaning in appreciation of whatever Ruth was doing to her that I couldn't see. The aching cock was troubling, and I desperately wanted to go and offer it to Kate's mouth, or to the pussy she was eating. I didn't though, this wasn't the time for cock. This was for Kate to experiment and experience, so I left it all on her terms. I was playing the long game! They didn't 69 for long when I was there, as it was getting close to 21:30 and we needed to sort things out before Simon got home. The girls just sat up on the floor and we briefly talked. I asked Kate if she'd enjoyed herself and she said yes, very much. The girls then started to look for their clothes so they could get dressed and we could tidy up. Ruth took a while finding her bra, and couldn't find her knickers at all. It turned out the were on the armchair with me, next to my leg. I tossed them across to her and she laughed and said "cheers mate!". By the time Simon got home, it was as if nothing had happened. He found us all sitting in the living room, chatting and drinking. After dinner and more drinks, we eventually all went to bed. Kate was tired, but she thanked me for being so understanding and supportive and she at last took care of my cock, with a little sucking before climbing on and riding me slowly and gently. We were in somebody else's house and didn't want to make any noise, after all. After only a few minutes, I shot a massive load of spunk up into her well used pussy. A few seconds later she orgasmed quietly and slipped off my cock, curling up to sleep naked and happy.

In the morning, I asked Kate how it had all started. Apparently as soon as I left to get drinks, Ruth said to her "you're so beautiful, can I kiss you?". Kate said yes, and they both stood and walked in to the middle of the room where I found them. While I was in the other room, Ruth had fingered and rubbed Kate to her first orgasm, before giving her her second with her mouth. She came two more times, from a mixture of hands and mouth. She said Ruth was amazing, and was unbelievably good at eating her pussy. Ruth only came once apparently, from Kate's hand and mouth that time I'd seen her in the chair. Kate said it was a great feeling making another woman cum, and that she loved the taste and feel of her pussy and the sounds Ruth made. She loved all of it, not just the sex - the softness of the kissing, the feeling and exploration of each other's bodies. She was very keen to do it again.

And do it again she certainly did. Ruth and Kate became good friends, and lovers. Pretty much every other weekend the same thing would happen. Ruth would come to ours or we'd go to hers, and the girls would fuck. It was usually while I was there but not always, they were occassionally alone. This continued for a couple of months, before we extended it into same room sex (own partners) with Ruth and Simon. Overall, Ruth and Kate were fucking regularly for almost two years.

If anybody is still interesed in all of this, I'll tell of these sessions, the threesomes I had with Ruth and Kate, and the first time we actually swapped with another couple.
