We have a friend called Jack who often helps us with DIY etc. and although I try to pay him he says that he enjoys doing the work as it is better than staying at home on his own. Jack has been retired about 8 years and widowed for about 5 years. He keeps himself fit and is quite muscular for his age which is probably late sixties. Personally I think he likes coming to our house as he gets to spend time with my wife, who is very attractive and has a lovely curvy size 14 figure., and I think still very pretty. She has nipples like organ stops and often goes bra-less so with a thin blouse they stick out even when they are not hard. As a way of repaying Jack he often comes for dinner, and will pop in for a beer some evenings. And my wife will cook him lunch when he comes around to do some painting or building work. One late evening after dinner and quite a few glasses of wine Jack was a bit drunk to go home so my wife suggested he stay in the spare room. We went to bed and I said to my wife that Jack had been staring at her boobs most of the night and she said that she had noticed and she even thinks he had rubbed himself a couple of times during the evening when he thought she hadn’t been looking. She went to the bathroom and as she passed Jacks door which he had left open she could see him get undressed down to his pants. She said that he had quite a bulge in his pants and said he had a very nice body. I suggested that she went to check on him to see if he was ok and she put on a chiffon nightgown and went to his room. I heard them chatting and then it went quiet. But I could hear the bedclothes rustling. I went to the landing and could see from the light of the street lamps that she was sat on his bed and he had the bedding pulled back. It was very dark where I stood so they couldn’t see me. His hand was caressing her boobs and her hand was rubbing his cock. She suddenly took off her nightie and laid next to him. They were kissing and his hand was between her legs and she was moaning. He suddenly got on top of her and started slowly thrusting into her. She gripped his bum and pulled him and he got faster and fucked her harder. She was moaning quite loudly and suddenly had an orgasm followed by him groaning loudly and holding himself tightly into her as he came. He seemed to cum for ages and she held him as he enjoyed the pleasure from her body. He thrust a few more times to finish off and then collapsed onto her and laid quietly for a few minutes. She gently pushed him off and got out of bed and came back to our room. I quickly got into bed and she just came in and sat on me and used me to cum again. She came very quickly which was good because I lasted about 2 minutes before I also came in her. The feeling of being in her after another man was incredible. Smooth, warm and very very slippery. We had never done anything like this before but had talked about her using another man. Jack’s name had been mentioned a few times so she said she knew I would enjoy her being with him, and thought that was my idea when I suggested she checked on him. She went to his bed twice more during the night, once when I was awake and another early morning when I was still fast asleep. Both times he came into her and she enjoyed an orgasm. In the morning she took him tea in bed and got in for a cuddle and ended up using him just for her pleasure. It has become a regular thing for Jack to stay and during the evening they will kiss and cuddle and grope on the sofa whilst I sit and watch. He also turns up occasionally during the day and she enjoys it when he just uses her for a couple of minutes to satisfy his lust.
