Swingers stories and erotic fantasies

my wife and i are 34 years old , she has blonde shoulder length hair a 34b 25 35 figure and is 5ft 6" tall. we were in bed one night and as she was sucking my cock i said to her that i was imagining that it was jims cock she was sucking. jim is an old man in his late 70 s who sits in a group with us in our local. he is always watching her and every time she goes out for a smoke , he goes as well.he walks with a limp and uses a walking stick. so the wife said , next time we are out ,if he is there i will tease him.
anyhow ,saturday came and on the night it was quite warm so the wife wore a short denim miniskirt , high heels and a thin blouse. we were at the pub and as usual jim turned up and when he saw how short her skirt was he got as close as possible, he kept looking down and at one point he got a glimpse of her panties,she started to tease him and when she went to the toilet she took them off, she came back to her stool and she sat so that he could see she had taken them off.
about midnight ,there was only the 3 of us left so i ordered a taxi and when it came i asked jim if he fancied a drink back at ours, and he said yes.we got home and had a drink , then i asked if any one fancied a take away. they said no but i said that i was going to get myself one , as i left i winked at the wife. i went around the back and watched them through the window jim was on the couch and the wife was on a chair talking to him, i rang the wife on my mobile and told her to say i would be about an hour and to see how far he would go.
she went and got him another drink and this time sat next to him. she started teasing him and she asked if he still got hard at his age and started stroking his cock through his trousers, she soon found that he did so she unzipped them and put her hand inside, i heard her say my god that feels big and when she pulled it out it was a good 10" ,she started sucking it and rubbing her clit at the same time ,then she stood up and told him to lay down on the rug so he went and lay on his back with his trousers round his ankles and the wife opened her top and removed her bra and lowered herself onto his cock she had her back to me and i could see her shaved pussy stretch over his cock she rode him for about 10 mins,all the time i could see his cock slide in and out, then i heard her tell him that she was comming, she got faster then they both came together, he came loads because it ran out of her down his cock, and when she got off him she sucked and licked his cock clean, i heard her tell him that they had to do it in bed next time ,and they got dressed. i went home 10 mins later, jim got a taxi and we went to bed and and i fucked her still wet pussy. i wll tell about the next time later
