During the building of an extension at home, the neighbours across the road were intrigued that we were attaching wooden shingles to the outer wall. One - the demure 62 year old lady - looks like 45 - came across with a drink of orange juice for me as it was hot day. Looking down I could see that she had on shorts and T shirt so I shouted bring it up the ladder. She told me that she doesnt do ladders so I climbed down and said "Come on let me show you around. I can walk behind you as you go up and will help you down later". Lots of hesitation but I thought there is no way I'm letting this chance pass by. She accepted that she would be safe and set off in front of me. I did what all gentlemen do I watched her arse wiggle up that ladder and got hold of her at the top of the scaffold to steady her before we set off around the extension for the guided tour. I knew nothing would happen at the front of the house as we could be seen from the road but when we got round the back of the property I helped her to retain her balance by touching her arm and holding her waist. After the tour of the works she asked if I could help her remove some dust from her eyes which I proceeded to do. At the same time I told her she smelled gorgeous and looked fantastic for her age. I couldnt help brushing her tits as I dealt with the dust issue and at the same time she asked me whether I thought we would be seen from ground level if she took out my dick and sucked it. No chance of being seen I said if we go inside the extension and use the cavity wall insulation boards as a mattress. She was in there like a shot to say she didnt do heights and was facing me without T shirt - no bra - by the time I climbed in through the window opening. She almost ripped off my shorts and blew me with some gusto to witihn an inch of come erupting into her mouth. "Now now" she said "You dont get away that easy - take off my shorts and do me." Naked and both lying on the insulation I sucked and licked until cum ran down her inner thights. For an old bird she sure was wet and came easily a number of times. She turned over and wanted it from the back as her hubby didnt do anything adventurous just missionary. She yelped and moaned until I could hold it no longer and showered her in spunk. "Thanks" she said - "same time tomorrow?" At that she stood up; said "I love climbing up and down on poles"; climbed out of the window opening and was gone. I put the insulation into the cavity wall to hide the knee indents and cum smell. Cant wait for tomorrow.
