This happened last week. I,m Scott (32) and my wife is Sarah (28). I was up early so went outside to admire my handy work in the garden as, the previous day, my wife and I had been getting rid of a lot of old plants and putting down bark, which opened up the garden. I was standing on the patio when I noticed our neighbour Bob (70ish) doing some tidying up of his own. I asked him how he was doing and we chatted away. I heard a shout from my house as Sarah wondered where I was. I let her know I was outside and told her to join us. She came out wearing just her white nightdress, which until now, I hadn’t realised was so see-through. You could quite clearly see the outline of her breasts, her nipples and the dark hair of her pussy through the thin material. I didn’t say anything as she came over to where we were standing and joined in the conversation. I could see from Bob’s expression that he had noticed my wife’s body was pretty much on display and couldn’t take his eyes of her breasts. I suggested that Sarah have a look around the garden. This gave us a great view of her rear as she walked away and allowed us to see her breast jiggle when she rejoined us. We stood for a while just talking and I noticed that Bob had slipped his hand in to his pocket and was giving himself a rub as he continued to enjoy the view. I told him that we were just about to have a coffee and asked if he wanted you join us. He immediately agreed and said he would shut his back door and then come round. As Sarah and I went in the house I told her about her nightdress. She was embarrassed and said I should have told her. I told her about Bob playing with his cock as he looked at her and she first seemed shocked and but then quite interested in the effect she had on him. I asked her what she was going to do. She said, if I wanted, she would continue to put on a show for him when he came round. I told her I did. Bob arrived a few minutes later and joined us in the kitchen. Sarah had the coffee on and floated about getting out cups and sugar. She then had to bend down to get milk out of the fridge. She made a fuss about the fridge not being tidy which meant she stayed bent over longer than needed. This gave Bob and me an excellent view down her front and we could quite clearly see her breasts. She asked if we minded if she tidied it now. Bob immediately said it was OK and his hand was back in his pocket and moving quicker than before. Sarah was now on her hands and knees with her bottom towards us. The material was clinging to her and in all honesty it would have made no difference if she had a nightdress on or not. You could see every curve. With all that was going on I was starting to get a little hard myself, so god knows how Bob was now feeling. Anyway, the fridge was now tidy and she stood up and joined us with the milk. We all headed through to the conservatory with our cups. Bob and I sat on one sofa and Sarah on the other. Sarah had her legs slightly apart but not enough you could see anything but the hint was there. I noticed Bob adjust his position so he could get the best view possible. I could tell that Sarah was getting turned on now as her nipples were hard and now straining through the flimsy material. She opened her legs a bit wider so Bob could get a glimpse of her pussy. She then teased him by shutting them again. It was obvious that Bob’s cock was now hard and was clearly visible through his trousers. It was the next bit that took me totally by surprise. Sarah looked at Bobs bulge and said that she thought that he looked a little uncomfortable and that maybe he should get the poor thing out and, as she was feeling turned on, she would really give him something to look at. With that she pulled her nightdress up to her waist. She then sat with her legs open. She started to stroke her pussy. I could see that she was wet and she easily inserted a couple of fingers in to her hole before starting to rub her clit. Bob didn’t waste any time in dropping his trousers and rubbing his cock furiously as Sarah was bringing herself close to orgasm. I couldn’t wait any longer and quickly got my cock out for a good wank. Bob was staring at Sarah’s soaking, wide open pussy and it didn’t take long for him to groan and fire a jet of cum on to the wooden floor. I wasn’t far behind him and soon delivered a big load of spunk on the floor. Sarah took her fingers out of her pussy and licked her juices off them. She said that we had been naughty boys for making a mess and that she would have to clean it up now. With that she got up and crawled over to our spunk and started to lick it up like a cat. She then came over to me and licked and sucked my cock clean before moving to Bob where she gently took hold of his deflated cock and licked the head before sucking him clean. She then, as if this happened all the time, stood up and announced that she would have to leave us as she was going to have a shower. With that she walked out of the room leaving Bob and me staring at her ass as she left. Bob turned to me and said that had been fucking incredible and something along the lines of we must do this again sometime. He stood up pulled up his trousers and headed home. I went upstairs and joined Sarah in the shower where I fucked her hard until we were both exhausted. I told her what Bob had said about doing it again sometime and that I was up for it if she was. She said that if the mood was right we could have him round some night and see what happens. I can’ wait!!
