We've been married for 10 years and our sex life is good. We started experimenting with our sex life about two years ago, using toys and fantasy role play, so nothing extreme. We did once have a female third party join us and this was pretty good for both of us because my wife enjoyed playing a lesbian role for me. However recently my wife asked if I would consider something she had seen in a porn film she had viewed with a friend. Would I consider fucking her with another guy? I had fantasised about seeing her screwed by someone else, so I said that would be great. She then explained exactly what she wanted, and I was quite shocked. She wanted two cocks inside her, but she definitely wanted one to be mine. I had never considered what this would be like, apart from wondering if it was possible, my cock would be rubbing up against another man's penis. She explained it was definitely possible and persuaded me that it would be very erotic for me too. The more I thought about it I found I was quite turned on by the idea. She said she needed to find the right guy online, and after reducing the choice down to two she asked my opinion. One guy was about the same age as us, and was looking for a new experience. The other was about five years younger than my wife, and therefore ten younger than me. He also had done the two cocks in together several times and said he would nurse us through it. Since he was also good looking we chose him and my wife arranged a meet in a country hotel. When he arrived we had several drinks to relax us, and he was good at putting my mind at rest, because I was concerned it might hurt my wife and also about the intimacy necessary between me and him. He said it would be great, so we went up to our room. We both got on the bed beside my wife and started kissing and fondling her. I could see a bulge in his trousers as she rubbed his cock. She suggested we get stripped. I am reasonably well endowed, about eight inches He was about the same but his cock was really thick with a massive bell end, and very veiny. My wife smiled when she saw his erection. After some oral foreplay between the two my wife said she wanted fucked. He asked me to lie on my back and she was to (rather awkwardly) straddle me but facind him. He told her to mount my now engorged cock but not right down on it. Her gash was now facing his erect member. He rubbed on some lube over his cock. I could see this in the mirror, since my view was of my wife's back. He then rubbed the tip of his cock over her cunt, she moaned in anticipation. I could feel his bell end at the base of my cock, pushing my cock downwards. He then deftly eased the tip in. My wife let out a small gasp, but not as much as she did when he slid his whole length into her. He urged me now to push in fully and to be guided by his tempo, which was quite gentle. I was mesmerised by the feel of his thick shaft against mine. Soon we were fucking her with a slow action. She was gasping and moaning with pleasure. After about ten minutes her whole body shuddered in orgasm, and she just about collapsed above me. At this he withdrew and I brought my cock out too. He suggested a change of position for her. We moved nearer to the edge of the bed. I was still on my back, my cock throbbing. She again mounted me but this time in the more conventional way, facing down on me. I felt him grasp my cock against his. He was standing at the edge of the bed and was going to enter her doggy style, but he guided both our cocks into her together. It was the most erotic thing I had ever had done to me. This time his thrusts were rougher and more frantic but I kept up with him, trying to match his timing. Soetimes we lost it and he was thrusting in as I thrust out but this was fantastic as I could feel his bell end move the whole length of my cock. My wife reached a second shuddering climax, and was now out of any control. She was yelling fill me with your seed, both of you! I thought I would come first but then I felt his spunk channel twitch and could feel his spurts shooting inside her . This tipped me over the edge and I shot my load, mixing my spunk with his deep inside my wife. We relaxed with another drink. My wife then asked if she could give him a blow job. I said he deserves it. She sucked him back to full size, and teased her tongue around his throbbing monster, licking from the base to tip then taking his lengthin as far as she could. She kept looking me, and I could not stop staring, my own cock now returned to full erection.She asked mt to go down on her while she sucked him and of course I was licking up the loads of come we had deposited in her. She then said to me to watch her bring him off, and I could see he was getting near. She sucked and licked right in front of my face. She then said why not try a taste? By this time I was wanking furiously and was beyond any line I would not have crossed previously. I joined her in suckingand licking the huge bell end, our lips meeting as we kissed the thick shaft. He gave a grunt and shot about six huge spurts of thick come on our faces and into our greedy mouths. Ihad stopped wanking to concentrate on sucking but my own cock exploded, spurting my come onto the carpetAfter this we thanked him and he left. We fucked about another three times that night. Truly memorable, and we intend to repeat it.
