I’m 58 and my wife is 45. She’s attractive, has an extremely athletic physique with large heavy breasts. Our sex life was ok but as strange as it sounds, I preferred penetrative sex where’s my wife was obsessed with oral sex. She would cum hard when I came in her mouth. 9 out of 10 times we had sex it would be a case of my wife in her knees sucking and tossing me off until I came, and because I ejaculate a lot of semen when I cum she would be gasping and gulping it down and would struggle to breath sometimes but she loved it. There were times when she would take some in her mouth and et the rest spray onto her tits which is great now and again to see her perfect, full, fat tits dripping with my cum. Then, when she had what she wanted she would sometimes demand I fuck her. All this sounds like a mans dream wife and dream shag but now and again is ok but to have your wife pushing her tongue in your mouth when its covered in your own cum and have her sticky body under you can be a bit off putting. In the end we would argue a lot about sex and even stopped fucking for a while. Then we went on holiday. We hadn’t had sex for about a month before the holiday, but the sun seemed to be an aphrodisiac and we had some great sex when we arrived but as usual, I had to fuck her mouth. Two days later we were walking through woods near our hotel which led to the beach. The wife was wearing a sarong round her waist and just her bikini top covering her large breasts and I have to say, she looked hot. We knew that there was a nudist section of the beech and had talked about wondering down there but that started an argument about our sex life. The wife said something about me probably finding someone I wanted to shag because I clearly don’t want to shag her. We didn’t talk for about 10 minutes until we came to the end of the woods and we saw a guy showering bollock naked under the public shower at the beach. It was more in the woods that actually on the beech so pretty private. My wife stopped and gasped, looked back at me then back to this guy. He seemed like a local (found out later that he was). He had dark skin from being out in the sun and looked quite fit. He looked at is and continued to shower. The wife blew out and said ‘ok’. I said ‘ok’ what, she just said ‘nothing’. I knew the sight of this guy turned her on because when she’s turned on her nipples get bigger and I could see that they were a lot bigger. We continued down the path. I said something like ‘there we are, a cock for you to suck’. My wife replied, it’s very suck able. As we started to pass the guy turns and smiles at my wife and she smiles back. I said (not thinking he could speak English) why not ask if you can give him a wank to which he replied, ‘you can if you want’. I was embarrassed but my wife laughed at me and said ‘maybe I will’. I walked on and left them talking, him under the shower with his cock on show and my wife doing that ‘head on a slant’ thing she does when she flirts. I was pissed off with her and said ‘go on, toss him off and maybe you can suck him off as well’ which was very childish of me and cost me my dignity. I walked on occasionally looking back. The first time she was flirting, the second time she was under the shower with him. Someone past and she stood back. I stopped to wait for her, she looked at me and just stared so I made a wanking motion with my hand. My wife went back under the shower and put her hand on his chest. Seconds later her hand slid down and round his cock. She looked around before starting to slowly toss his off. I just stood there, angry but turned on at the same time. Someone else past and she had to stop but as soon as the they had past, she was wanking him hard. I stood and watched for a good 5 minutes until she fell her to knees. I half expected her to put his cock in her mouth but instead he just came over her neck and chest letting out a loud grunt. Then, she gets up, kisses him on the lips and walks away. Needless to say, we didn’t talk for hours. In the end she told me to grow up and that I had told her to do it. I said’ so if I told you to fuck him, would you’. She smiled and said probably. The next day around the same time I suggested that we see if he’s there again. I had decided that it was just safe fun and why not. We walked back to where we had seen him but he wasn’t there, then there was a loud ‘hello’ in a strong Spanish accent. It was my wife’s new wank friend. As he passed me he put his hand on my arm and said, ‘hello my friend’. He looked around, stepped out of his shorts and got under the shower. My wife joins him but says nothing but puts her hand round his fat cock and tosses him off. After a few minutes she gets on her knees, look over to me and tells me to keep a look out. The beach seemed deserted. I looked back. My wife was on her knees, this strangers cock in her mouth. She was massaging his shaft, giving him a hand job and sucking him off as well. He had her hair in his hand holding her in place. I was trying to wonder if this was going too far or was still just fun. This goes on for about 10min or more but seemed forever. I was keeping a look out occasionally looking back to a muffled grunting sound mixed in with a clearer groaning. He says something and my wife pulls back just in time for this guy to cum all over her face and tits which were now on show after one of them had pulled them down to her stomach. Then, the same as the day before, she got up, washed his cum off her face and tits, kissed him and walked away. I had to endure this ritual for a few days where on day for she let him cum in her mouth. On day five we gave it a miss. She explained that she felt she had gone too far and was sorry. Se had great sex and talked dirty, whilst we fucked, I asked her if she was imagining his cock inside her, she panted ‘yes’ she said. We both came hard. After a few minutes of silence, I turned to her and told her that she could fuck him if she wanted. I immediately regretted it as she turned over and went to sleep. As we rested, she asked me if I had ever wanted to see her fuck another man, I told her that I had never wanted to see her with another man and how much I loved her. We fucked again. Day 6 was uneventful but on day 7 at around the same time my wife said she was going for a walk. She was wearing a white skirt and flowery top and I noticed that she wasn’t wearing a bra, in fact a number of people noticed she wasn’t wearing a bra as she walked, and her tits bounced and swayed. I asked her if I could come along, she said that she would be fine on her own. I laughed and told her not to get her clothes wet. My wife looked back at me and said nothing. I left it for about 15 min but all sorts of things were racing around in my head. We knew nothing about this guy, her could be a murderer or a rapist, I told myself that I should have gone with her. I got up and made my way to the shower area. There was no one there. I got closer wondering if my wife had gone for a walk in the woods. As I got closer to the shower, I saw that it had been used, another younger couple were passing, they looked into the wood, she covered her mouth and said something muffled. Her boyfriend / husband looked over and laughed out loud. They stopped to look then saw me and walked on laughing about how they couldn’t believe it. I walked to where they had been watching but before I got there I could hear a faint groaning and whimpering. As I got closer, I saw one sandal that I recognised, then another. Then my wife’s blouse caught on a branch. I walked into the wooded area I passed a white skirt. I could see two figures in a small clearing, and I saw a pair on knickers and a pair of shorts and an old short sleeve shirt. I remembered telling my wife that she could fuck him if she wanted and regretted it again, then I wondered, what if he was forcing her. I got closer and say my darling wife on her back naked, her legs raised with her feet crossed over his back. I listened to him grunt as he thrust himself into her over and over again. He said something I didn’t catch, she replied ‘no its ok, just keep fucking me’ followed by ‘be gentle’. I stood there and watched my beautiful wife on her back with a total stranger inside her. Her slowly thrust his cock into her pussy whilst they sucked each other’s tongues, her breasts laying either side her his chest, her nipples long hard and deep red. I watched him put his arms under my wife’s legs and lift them so her knees where her face. His thrusting became stronger, he kept muttering something I couldn’t make out, my wife repeated over and over ‘keep fucking’ and ‘Oh fuck your so hard’. Then he grunted and said something again. I was both devastated and aroused and had my cock in my hand. I wanked myself off not caring if someone else or that young couple had come back. I only lasted a few minutes until I shot spunk catching the branch of some poor tree. At the same time but after what I guess was a good 20 minute or so of fucking my wife, he became aggressing, pumping my wife’s pussy, gripping her left breast and shoving his togue into her mouth. He pulled his head back just as my wife shook, her toes curled, and she let out a long and loud grunt. I know my wife, and I knew that she had cum hard and so did he. He grunted and gave her three or four hard thrusts until collapsing onto her body. I tucked myself away and left passing the young couple who had indeed come back. They looked at me and I looked at them, the two of them in awe. I have no ideal how much they say but I think they heard and saw enough to know that my wife had just shagged a guy in the woods. I went back to our room and waited. I didn’t need to wait long until she comes in, in a mess. Her skirts full of sand and other things. Her blouse crumpled and dishevelled, her knickers in a ball in her hand. She looked at me for a second then asked me if I had enjoyed watching. I said that I didn’t; know she had seen me. She said, ‘of course I did’ and went for a shower. The next day at the same time she went for her walk, I followed her but this time he had her against a tree, her left leg round his waist. I guessed that she didn’t; want her clothes messed up. I watched him fuck my wife standing against a tree. To finish her off her turned her round, bent he rover and with her hands gripping a thin tree trunk he fucked her doggy style, her tits out and swinging wildly. I had my wank and watched. For the last three nights of our holiday my wife and I actually started our swinging lifestyle and invited him back to our room where we shared her, taking it in turns to fuck the love of my life. I had to endure her begging him for more until he pumped cum into her pussy leaving her begging for more. I had to endure him giving me permission to fuck my own wife and I had to listed ot her whimper whilst I fucked her letting out a faint grunt until it was his turn again and I had to listed to the ‘oh fuck your so fucking hard’ and ‘ keep fucking me you bastard’. Then there was the ‘oh fuck you have so much cum, keep it coming in me’. One evening I even slept on the sofa only to be woken at least three times by my wife and this guy fucking again and again. Since our holiday we have only met other couples three times. We have had great shags but the best thing of all is that we have our sex life back. We fuck properly four or five times a week, so much so that I have to take a little blue pill now and again just to keep up with her. And of course, I am ok with her sucking me off now and again.
