Dave here again, to tell you more of the great sexual adventures my wife Kate and I have enjoyed. This is the fourth entry and like the others it is true.

The first three 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

Ruth: Kate's First Woman - how my friend Ruth seduced Kate one night, which led to them becoming lovers

At the end of my last installment, I said that Kate and Ruth had become lovers and regularly saw each other. This started straight after that first session at Ruth's house. Most weekends Ruth would come to ours or we'd go to hers and the girls would play. Ruth's boyfriend Simon didn't know any of this was going on, he thought Ruth and Kate were merely good friends. He was still working late shifts, so they had plenty of opportunity. It happened sometimes through the week too. My job required me to work late occassionally, and one time I got home at about 20:00 to find Ruth at the house. She and Kate were sitting on the couch, Ruth's jeans were down at her thighs and Kate had her hand down the front of her knickers. Ruth had popped in on her way home from work and was killing time before collecting Simon from his work. They didn't flinch when I entered the room, they just said hello. Very strange I suppose, but it all just felt so natural. A week or so after that I got home late again to find Kate on the couch with her top open and Ruth sucking at her tits. Again perfectly natural, and to all three of us it just felt like I'd caught them drinking coffee or something equally innocent. Between these and the weekend encounters I was getting pretty used to having my own private lesbian floorshows!

One night when we were round at Ruth's place, Simon was there too. His shift patterns had changed. Again, we were round for dinner and to stay the night, the same as usual. With Simon there though, Kate knew she'd not be getting skillfully eaten out by Ruth that night. After dinner, Ruth put on a DVD for us all to watch, and shut off the lights in the living room. Ruth was sitting next to Simon on the Sofa, and Kate and I were on separate armchairs on opposite sides of the room. The only light in the room was coming from the TV, so it was pretty murky and flickery in there with occassional bright spells, but I did notice about 20 mins in to the film that Ruth was now sitting on Simon's knee. Shortly after that I looked up at them and saw that Ruth's top had been opened up and her tits were free, with Simon feeling them. I got Kate's attention and nodded towards the sofa. She watched them in disbelief for a few seconds, but we then carried on watching the film to leave them to it. 10 or so minutes after that, I asked if anybody needed another drink (everybody did) so I stood and started to walk to the kitchen. As I walked past the sofa, I noticed that Simon's cock was now out and Ruth was slowly wanking him. She looked up at me and smiled. I was still very surprised by this entire development, a little in shock. When I came back to the living room with the drinks, Kate had moved to the chair I'd been in and had her hand down her front, masturbating as she watched Ruth sucking Simon's cock. She then sat on my knee on the armchair, and we both watched them. I opened Kates top to access her tits and for Simon to see them. I squeezed and licked at them and then I took over the hand work on her pussy. I was wondering if Ruth was as good at sucking cock as she was eating pussy, and it certainly looked like it. She was blowing him without using her hands, occassionally making his cock completely disappear as she deep-throated him while he watched Kate's tits bouncing as I fingered her. He didn't last long, and soon he shot his spunk into Ruth's mouth which stayed clamped on his cock throughout his orgasm. She lifted her head, pushed a little spillage of cum from the corner of her lips back into her mouth and just laughed out "sorry!". The show having now finished and despite not yet cumming, Kate pushed my hand away, closed her top and went back to the other chair. It wasn't much later by the time Kate and I went to bed and I fucked her brains out, neither of us caring about being discrete with the noise of our fucking this time. At work on Monday, I asked Ruth what that had all been about and she said that she'd been talking to Simon about their sex lives and her swinging past, and what happened that night was something that he wanted to try. Kate and I certainly weren't complaining.

Kate's sessions with Ruth continued, despite this development. It had always been just the girls playing, usually with me watching, but one Sunday afternoon when Kate and Ruth had been together on our bed for about an hour, Kate lifted her head from Ruth's pussy to say "come here" to me. I stood up from my chair in the corner and started to walk towards them, and Kate added "take your clothes off". I stripped, and with my cock sticking straight out in front me I approached the bed. Kate turned so she was sitting on the edge of the bed and immediately put her mouth around my cock and started to blow me. Ruth rearranged herself too, and she was now lying on the bed with her head a foot or so away from Kate. She was intently watching her sucking me, and she was wanking. Before long, Kate stopped sucking and lay back on the bed and told me to fuck her. In no time at all and with Ruth lying next to us masturbating I was fucking my horny wife. Kate asked me to fuck her from behind and got on her hands and knees between Ruth's legs with her face near her pussy. Kate didn't eat or touch the pussy, but Ruth carried on wanking inches from Kate's face while she watched closely. I was kneeling behind Kate, fucking her as hard as I could get away with and it didn't take long for me to fill her with cum. She'd already orgasmed, a minute before me, as had Ruth. I pulled back from Kate, and noticed a dribble of my spunk leaking from her pussy and plopping onto her thigh. She got up and went to the bathroom to clean herself up, leaving Ruth and I lying naked next to each other on the bed, with my cock still rock hard and pointing at the ceiling. That was a strange moment. Ruth and I were very close friends, almost like brother and sister, and here I was lying naked next to her with a hard cock, shortly after she'd watched me fill my wife's pussy with spunk. She broke the tension by saying "so, nice weather we've been having". I laughed and agreed. She then said "nice cock" and I replied "thanks, nice tits" and she laughed "thanks". Kate came back into the room and looked surprised at seeing us. "Oh", she said, "I thought you'd be fucking". Here's the thing though. Ruth and I never did. No sex, no oral, no touching, nothing. Over the following years I slept with her twice, wearing just boxers and her just in knickers, but that was literally all we did - slept. Once I'd been introduced into Ruth and Kate's play, this sort of threesome became quite frequent. I wasn't always included, but Ruth and Kate would pleasure each other and at the end I'd be invited to join them to fuck Kate. When I was with Kate Ruth never touched her, she just watched and masturbated - often to orgasm. Ruth would one day say that she didn't like the suggestion that a woman couldn't satisfy another woman, and the she needed a man to finish her off. Kate reassured her that it wasn't like that all, she was always completely satisfied but sometimes she just really wanted to fuck me too. This first time, when I was lying on my back next to Ruth Kate noticed I was still rock hard and so she climbed on top to ride me. Ruth got up and started to find her clothes and get dressed, while I came into Kate again shortly before she came for the last time of the session.

Simon still didn't know about Ruth cheating on him with Kate, but the same room stuff we all did continued and became more adventurous. We'd all get together at one or other of our houses, and after dinner and drinks we'd start to play. Initially this was mostly just titillating showing of breasts and suchlike, but before long Ruth had sucked Simon's average sized cock in front of us again. One night, Ruth and Simon had been playing on the sofa while Kate and I played on the armchair. Ruth had sucked Simon's cock again, he shot onto her gorgeous tits this time, and Kate was completely naked sitting astride and facing me, as I sucked her tits and rubbed her clit and pussy. Ruth and Simon left to get more drinks, leaving Kate and I to what we were doing. "Fuck me", Kate moaned. I said "here, on the chair?". She said yes, and when I said that Simon and Ruth would be back any minute Kate said "I want them to watch". So when they came back in to the room, Ruth and Simon froze and just stood staring at us. I was sitting back on the chair, and Kate was facing away from me and towards them. They had a great view of her bouncing tits and the pleasure in her face as she rode me, my cock repeatedly disappearing into her soaking pussy. They sat back on the couch and watched us, with Simon watching particularly intently as Ruth pulled at his hardening cock. Ruth had seen dozens of people fucking, but this was a first for him. Kate came powerfully seconds before I did and after settling fully down on me with my cock totally immersed for a moment, she lifted herself off. A large dollop of my cum fell out of her, landing on the carpet, and as I sat there with my cock sticking up and glistening with a mixture of Kate's juices and my spunk Simon whispered something to Ruth, who nodded and laughed. From then on, we would fuck our own partners in front of each other at these gatherings. One day a bit later I asked Kate what Simon had whispered to her that night, and she said it was the first time he'd seen my cock, or indeed any but his in that state, and he said to her that it was "like a fucking tree-trunk". Obviously I was pretty pleased with this compliment, despite his lack of expertise. Simon eventually found out about Ruth and Kate, and he wasn't pleased - fair enough, she'd been cheating on him after all. After a rocky couple of weeks for them she managed to talk him round and he realised that apart from it being behind his back, it was actually pretty great. After that, Ruth and Kate started to do it in front of his face too and the lesbian floorshows I'd been enjoying became part of our dinner nights. Simon very much enjoyed them too, and they would often be how things got started before he fucked Ruth as I fucked Kate.

Kate and I then started to talk more about properly swinging. Ruth had ignited something in her, in both of us really, and she was keen to experience different women. She also pointed out that although she'd often sucked the guy she'd been cheating on me with he hadn't fucked her, and in fact nobody but me ever had. She wanted to suck cocks that would stay hard enough to fuck her, she said. This was a good point. Kate's first two attempts to get a new cock into her pussy had ended badly for her. When she was 19 a friend of ours refused to fuck her one drunken night and left, after she'd shown him her pussy and directly asked him to. The guy she'd had the affair with hadn't been able to get it up despite her lengthy and patient attempts, so this all made her question herself, her sexual skills and her attractiveness. Her experiences with Ruth were very reassuring for her, and she realised that she was an attractive and sexy woman that guys and girls would want to fuck. She said that she also really wanted to watch other women enjoying my cock. We didn't want to swing with Ruth and Simon. Kate didn't really find Simon attractive enough to fuck, though she liked watching him and Ruth, and with the strange relationship Ruth and I had we'd never fuck each other anyway even if Simon had been balls deep in Kate right in front of us. So we joined a couple of swinging sites to dip our toes in the water. While we were looking for a couple to play with, our same room stuff continued, and Ruth and Kate kept seeing each other.

It wasn't long before we got a message from a couple who lived about 50 miles away that we liked the look of. Next time I'll write about when we met them and Kate got to taste a new pussy, and for the first time ever she finally got to enjoy the sensation of a different cock pushing in to her pussy.
