I posted the tale on here of how my wife, Sonia, has become a slut. It all started with her sucking off some lads in the dunes at Maspalomas, developed into sucking off guys she had just met in pub carparks, and she now has me taking her dogging at various local sites every few weeks. She started off giving guys a blow job, but this has developed into them fingering her first and, if she feels in the mood and she has a ‘spark’ for the guy, she may even invite him to fuck her, subject to using a condom. I suppose I should be unhappy with the situation, but it doesn’t seem to affect our sex life adversely, and could be even enhancing it. Sonia says she loves the thought that these men find her attractive and want her. She quite often orgasms when they finger her, and she finds the sex with me so much more enjoyable when we return home afterwards. A while ago, we had gone to one of our regular haunts to see who was about. When we arrived, we noticed a car with a young couple in it who were putting on a show for several men gathered around the car. I seem to remember seeing the car on a previous occasion, when one of the watching men had spoken highly of their performance. On this occasion, the show seemed to finish after we had been there for about 10 minutes, as most of the men wandered off leaving a couple of them to walk over to our car. By this stage, I had undone the front of Sonia’s blouse, putting her ample boobs on show, and I was busy trying to get my hand up her skirt so I could finger her pussy. I know she really likes me to finger her pussy as a prelude to sucking off another guy. Upon seeing them approaching, she hitched her skirt right up revealing that she had no panties on, which I find quite arousing. The two guys were standing on the passenger side of the car and began wanking their erect cocks. Sonia seemed to be reasonably impressed by them as she wound her window down half way to offer them a blowjob. Having negotiated this was what she was prepared to do, she got out of the car, pushed the first guy against the car and knelt down before him. She always likes to see the whole thing, so she undid his belt and pulled his trousers and pants down to his knees. She then grabbed hold of his cock with one hand and began licking his cock hungrily, whilst she fingered herself with her other hand. She obviously managed to bring herself to orgasm as she was panting and had to stop slurping his cock for a few moments, before resuming bobbing her mouth up and down on his cock. After a few moments, he announced that he was going to cum, Sonia said she wanted it in her mouth, and he grabbed hold of her head so he could thrust himself into her mouth. Sonia had a firm hold on the base of his cock, so he couldn’t make her gag, and she comfortably swallowed his cum. After he had finished cumming, she confidently gave his cock a little lick, stood up to peck him on the cheek and said “that was nice, thank you”. I noticed that the young couple from the other car were standing beside me watching Sonia’s little show. They introduced themselves as Gary and Helen, both I would guess in their mid-20’s, and quite attractive. He was about my height, slim and fit, and I would guess was quite sporty. She was a similar height, slim with very small boobs and short brown hair. I have never considered sex with other people for myself, but it went through my mind that I could certainly consider fucking her. We stood, initially in silence, as Sonia proceeded to suck off the other guy. Helen said she was amazed at how confidently Sonia handled the situation, she was sure that she couldn’t do anything like that. I noticed that they were holding hands and she squeezed his hand very tightly as the guy ejaculated into Sonia’s mouth. She finished off with her customary peck on the cheek and he zipped up and left. Sonia then turned to us and I assume she found Gary attractive, as she said “and what can I do for you then, you can certainly fuck me”. They both laughed, but I was fairly sure she was not completely joking. They introduced themselves to my wife, explaining that they were new to swinging and were trying visits to the dogging site to get some experience. Helen said she was amazed at how confidently Sonia handled the men. Sonia said it was all down to having me there as her ‘minder’, although I doubt whether I would be any use if she encountered a group of unruly men. They said they lived only a few miles away and suggested we go back to their place for a drink, so they could learn more from our experience. So, we ended up following them back to their house in our car. It was a fairly ordinary semi-detached suburban house, coincidentally on the other side of the town where we live. On the way there, Sonia said “I think they may want to swap, how do you feel about that?” I said that it wouldn’t worry me too much, but how would she feel about me being with another woman. She said “well I suppose it had to happen sometime”. When we got to their house, Gary opened a bottle of wine, and we sat down to talk, Sonia volunteered that our experience was limited to her “little bit of fun at the dogging site” as she put it. They were impressed with the confident way Sonia took control of the men, but seemed disappointed we could not tell them about swapping with another couple, as this was what they thought would be the next stage for them. I noticed Gary and Helen were glancing at each other occasionally, but I wasn’t too sure what they were trying to communicate to each other. I sensed right from the start that Sonia found Gary attractive – well what middle aged sexually active woman wouldn’t have the hots for an attractive fit man in his middle 20’s. It was, perhaps, a sign of their inexperience with swapping that there was no discussion of several key factors before Helen volunteered that they had only one double bed upstairs, so she and I would be going upstairs, leaving Sonia and Gary to the lounge. Having watched Sonia suck off numerous men, not to mention fucking a few of them, the thought of pleasuring another lady alongside her, while she was being pleasured by a young stud quite appealed to me, but they seemed to have decided that separate rooms was what they wanted. Sonia told me later that the thought of being serviced by a man less than half her age was such that she would have agreed to anything they suggested. I suppose the same applied to me really. When we got upstairs Helen and I quickly undressed and she pushed the duvet off the end of the bed. She seemed coy about revealing her breasts to me, keeping her arms folded across them, so I walked over to her to put my arms around her and kiss her on the lips. After a few moments, her lips sort of melted into mine, and she put her arms round my neck, allowing her tits to press against my hairy chest. The stimulation of her nipples seemed to have relaxed her even more as, when I suggested I remove her panties, she said, “oh yes please”. She moved onto the bed, as I removed my boxers, and I climbed on beside her. She was no longer trying to hide her assets behind her arms, and we quickly became locked in a passionate embrace. I like to take a dominant role with Sonia, so I assumed I would stimulate Helen orally first, but she wanted to give me a blow job first, which she did very expertly. I am quite used to Sonia giving me oral stimulation, so I am quite adept at holding back, but it became apparent I could not hold out forever, so I grabbed hold of her head and said “my turn now”. It was at this point that I realised we had not discussed the use of condoms either so, before we both got too excited, I asked her. She said she is on the pill, so she doesn’t need to worry about unwanted pregnancy. There was no mention of infections, but I decided that both our limited sexual experiences made it worth the risk. I went down on her, she was already quite wet and my oral stimulation quickly got her panting and gasping. I slid up the bed and, I don’t know what prompted me to do it, but I said “can I fuck you now?” Her reply was instant “oh yes, please” and, as I slid into her, she wrapped her legs around my buttocks to pull me in. It was at this point we heard Sonia orgasming downstairs, very vocally. I heard her shouting “yes …… fuck me with your big cock …… I love it …… harder …… harder” I started out determined that I would not cum too soon, but with this nubile young lady beneath me, who was demanding that I fuck her, it quickly became apparent I was going to cum, and she reacted to me splashing my sperm inside her with a massive orgasm. As we calmed down, I rolled onto my back beside her and she began licking my cock clean. When I suggested I should do the same for her, she said “no, I want to save that for Gary later”. It had gone quiet downstairs, so I dressed, Helen put on her dressing gown, and we went downstairs to find Gary and Sonia sitting on the floor leaning against the settee naked. He had half turned towards her, and was mauling her ample tits, she had one hand behind his head and was clearly enjoying the experience. We talked briefly and exchanged phone numbers, I had the impression they wanted to see us again at some stage. This was the first time I had had sex with another woman, so I was not too sure how Sonia would feel about it, but there was no adverse reaction on the way home in the car, so I think it may happen again. I have noticed that, in a lot of the tales here on SH where couples have been swinging, they feel the need to make love to their wife/husband when they get home. I assume it is something to do with confirming the closeness of their relationship immediately after they have had sex with someone else. It was the same for Sonia and I, we both wanted to fuck as soon as we got home, and I found that Gary had indeed fucked her bareback. I can’t quite understand why a beautiful young couple would want to continue having sex with people more than twice their age, but I suppose that is what sexual attraction is all about.
