I was laid under my car changing the oil as part of a service when a voice asked, "Mr D when you've finished what you're doing can you possibly have a look at a problem I have. I slid out from under the car. The sun was behind the woman and I could see up her skirt and straight through the rest of the thin material. It was Mrs G from two doors down. Now I knew for sure, she wasn't a true blond as she had no panties on and I could see the thick brown bush on her mound. I told her that I would be down in about twenty minutes. I had heard rumors that she was available when her husband was away, and that was quite a lot as he was a long distance lorry driver. Up till now other than the occasional hello or nice day, I had never really spoken to her let alone have anything further to do with her. I finished the service and after cleaning myself up I walked down to her house and rang the door bell. I heard her call to come in. I opened the door and stepped into the hallway. The voice called in here and I followed it into the lounge. There she was in a very flimsy nighty in the doggy position on the sofa. From my view she was still without panties. "Fuck me," she asked or was it an instruction. Regardless, my cock had growing rapidly. I stepped towards her and slid my fingers up and down her pussy. Diana groaned and pushed back at my fingers. I slipped one and then a second finger into her pussy. Diana groaned and continued to push back onto them. Between the groans she was pleading with me to fuck her. I was more than happy to carry out her wishes. I unzipped and placed my rock hard cock against her pussy entrance after removing my fingers. Diana quickly bushed back and speared herself on my cock. She let out a squeal as it penetrated and then moaned as it slipped fully into her depths. I held her hips still as I started to hammer her pussy with my cock. She was now in one long moan as I built up towards my climax. Diana beat me to it and was shaking from head to toe as it racked her body. Then my own orgasm hit and after three short deep stabs I filled her pussy with my cum. After we recovered Diana dragged me up to her bedroom. There we made love twice more before I finally staggered home totally exhausted. Needless to say I went back for plenty more shags. On Mr G's return he came and talked to me and thanked me for looking after his wife whilst he was away. I wasn't sure what he thought I had done for his wife until he handed me a packet of condoms and said that we don't want any accidents. From then on when Mr G was away I would spend as much time as I could looking after Diana.
