my wife Deb who is 53 and I live next door to a guy Derek who is 79 years old and widowed about 3 years ago and we have been neighbours for the last 10 years. We have looked in on Derek from time to time and make sure that he is looking after himself etc. Deb went around to do some cleaning for him as she now does on a weekly basis and she came back telling me that Derek has started to act weirdly around her and when asked what do you mean she told me that he has started making a few lewd remarks and she swears that he is flirting with her. I dismissed this but as the weeks went on she says it got worse and he would often comment on that if he had the chance he would if you know what I mean. I told Deb that she should call his bluff and he would stop. Well how wrong could a man be. deb went round last week and this is the story of events that she came back with. Derek was in the kitchen and she let herself in as usual and called to him and went in to see him. Derek was there sat in his PJ bottoms having a cuppa and he said "so Deb is today the day that we get it on" to which Deb said " well if you are a good boy you never know" and at that went off into the living room to start hoovering. About 10 minutes later Deb felt her hips touched and realised it was Derek and when she turned around to tell him off she was met with a surprise. Derek was standing there completely naked and sporting a semi hard on and a big smile on his face. Well my wife then did something that she thought she never would and reached out to touch his cock which began to get fully erect and she said that Derek was at least 8" and a good girth. She doesnt know why she did what she did and realised it was wrong but couldnt stop herself. Derek moved forward and said "i have been a good boy like you said now its payment time" he held Deb and began to unbutton her skirt and let it drop to the floor and then proceeded to pull down her panties. My wife told me she was getting so horny and just allowed him to do it and all the while holding and stroking his now bone hard cock. Derek pulled her to the sofa and sat there and beckoned Deb to sit on him which she did and as she rode his cock into her pussy he peeled off her top and bra and fondled her breasts which are 38FF with sensitive nipples. She told me that she rode him fully for at least 10 mins until he said he wasnt going to hold on much longer and at that Deb told me she climbed off and finished Derek off by sucking his cock into her mouth. When he came it was quite a load and she said she had trouble taking it all in her mouth and some dribbled out and down onto her breasts. We have talked about this and to be honest she knows it was wrong but she said she really enjoyed it. I have no issues with her having some fun as long as i know who with and if she wants to help Derek out again she probably will. I have told her that I would love to watch this happen and she needs to arrange this with Derek. I will post more should the event take place again.
