My wife and I have for all our years together shared our views openly. The first time we were in bed together I made a point of us discussing our fantasies and fetishes. This helped no end in making a strong base for the relationship and it has endured since 1982. One of my weaknesses is to allow Liz to fuck other guys and this has been a frequently repeated scenario with her taking lovers as she does prefer to establish a basis of friendship rather than risky one night stands or picking a guy up for a knee trembler in a back alleyway. However sometimes she does get sufficiently excited for her inhibitions to drop along with her thong and some guys got very lucky. A further fetish of mine is for her to flash her lovely body in public locations, pubs and clubs or as of later years, in swinging clubs where we find the ease and relaxed nature is a fabulous way of getting a lucky guy to feast his eyes on her well kept form. I find it a huge turn on when she is letting a guy see her well trimmed pussy. I want to let you in on the revelation from the mid nineties, we had been wed for twelve years and we had two daughters at home at the time so no chance for sex other than outside or in a hotel. We did not have sufficient funds to throw away on hotels so outside sex became the main option for adventurous sex out of the marital bed. Liz had gone out with some friends, she was thirty four at the time and a trim size twelve with generous boobs topped by perky easily excitable nipples. Her flat stomach led to neatly shortened pubes but not shaped, just short. Her figure was always enhanced by smart and sexy clothes, often skirts sporting the sexy slit at the side, and loose and low cut tops. Her underwear was always matching and usually extremely small panties and fairly regularly stockings with a suspender belt (you've got it, another favourite of mine). Thus dressed, she always left me at home with a raging hard on throbbing and my mind in overdrive wondering what she might get up to. I had agreed to meet her when she wanted to come home on this occasion. The night had gone well and she had been getting a lot of attention as she strolled from bar to bar in the centre of York. Around 11 she rang me from her mobile and said she had been a bit naughty, letting on a group of guys had been following her and three friends to four or five pubs and one was hitting on her big time. She revealed she had been kissing him and he had been fumbling around and mentioned how he loved stockings and suspenders. She let on that he was wanting to take her somewhere and see her in her stockings. I said she might let me know where he had in mind and I would see if I could get close by and watch. I got a second call and she said West Bank park in Acomb was being suggested. I knew it and knew there were a few gaps in the fencing that people could easily squeeze through and have the freedom of the open spaces. I said I would be there in ten minutes, popped my head round the door and told the eldest that I was going to pick mum up and to keep an eye on the youngest, who was sleeping soundly, I heard a grunt as she was ensconced in watching a late night film and took that as a yes. I was very soon at the park, well before Liz might be arriving. I found the gaps and sneaked in, just passing traffic on the main Acomb road making an indent on the quiet evening air. I waited impatiently for them to arrive, then I heard footsteps over to my left and saw two figures near the swings. I made out the shapes a man standing and a woman swinging gently, the swing making the familiar creaking. I walked stealthily through the trees unseen and found a nice view as I saw the guy removing her skirt. It was late August at the time and quite warm. Liz was making comments on him being far too overdressed and I saw her hand go to his crutch, as he was with his back to me I could only assume she was getting his cock out, but the jeans he was wearing suddenly dropped to mid thigh and she leaned forward, I saw her face at the right level and assume but could not see her start to suck on his cock. I was happily looking at this scene, the natural and street lighting gave a reasonable degree of visibility and I was not complaining as her top was slipped off and her bra undone by the guy while he was receiving her cock sucking. He took his own shirt off and stroked her head, pulling her face into his crotch, encouraging her to suck harder. After e few minutes he told her to stand up so he could get her knickers off. She wanked his cock a bit and said something to him before he asked her to let him see her take her panties off for him and show him her cunt. I saw her stand and return to the swing and then face him (and me) then slowly she removed her panties and stepped out of them and dropped them on the floor. She now parted her legs and put a finger in her slit, opening her lips. She strolled naked but for the black suspender belt and stockings around the play equipment and looked gorgeous. The guy said he was looking forward to fucking her. Liz posed several times and said he would need to catch her first and set off running towards a the bowling greens. He struggled out of his jeans and shoes then sprinted after her, catching her in the wide open space in the centre of the green, the dew made them slip and with a squeal she hit the ground. What a sight, my naked wife about be fucked in the open area. I decided to chance getting closer and fortunately he was more bothered about getting into her warm wet hole than being seen. His cock must have got in her as she wrapped her legs round his back and started breathing fast. His bum flashed in the moonlight as they fucked, I stood almost at the edge of the green and was so excited I began wanking in the open, not caring if he saw me, but hoping he would not. She was delirious saying how great his cock was and that she needed his spunk. I realised at that time that this was a bareback fuck and I was unsure if she would stop him and insist on a condom because of the risk. But they were past the point of no return and kept pumping each other, Liz begging for his hard cock to fuck her hard and fill her with spunk. I now lost my control and splattered my seed across the footpath. He tensed his arse and plunged deeper into her grunting as he gave her the juice she craved. The afterglow was brief, they got up and found their clothes, both giggling about the strands of grass on their bodies and complaining of the dew making their clothes cling to their bodies. He offered to get a taxi for her or stay the night at his place but she said she had a lift to organise and rang me. I had made it to the car and said I would meet her on New Lane in three minutes, drove round the block and met her as they emerged from the park. I smiled at him and said I hoped they had enjoyed the moonlight. She jumped in and we set off, stopping on the way home while she sucked me clean. A bath and her bum covered in grass clippings and a very adventurous fuck in our bed after, what a lovely night.
