With Sophie again

I've found myself in the very enviable position of having my neighbour Sophie watching me when I wank. It started quite by accident about 4 weeks ago when she saw me through the window because I hadn't closed the blinds properly. When she told me a couple of days later what she had seen, I was horrified but she admitted to having watched me and rather enjoyed it. I told her that I would give her a proper show next time and the following week I stood in the window with the blinds open and she watched me from her garden. Last week I persuaded her to come in and watch which she did. This morning as normal after a night out with the wife, I was doing what naked men do best and keeping an eye out for Sophie. As it got light I saw her come in to the garden and so I went to the window and waved at her and told her to come round the side of the house. She walked up the path and I went to the side door and let her in. I closed the door and turned round facing her. I was completely naked and semi erect. Sophie looked at me then looked at my cock and said I can see you have been enjoying yourself. I told her that I had indeed been enjoying myself and would love to carry on with her watching. She smiled and said well don't let me stop you. I started touching myself and within 60 seconds I was hard. I began slowly wanking for her and seeing her looking at my cock filled me with excitement. Sophie was fixed on my cock only looking up for a second every now and then. After 5 or 6 minutes I asked her if she was enjoying it and she looked at me and told me she was enjoying it immensely. She looked down at my cock and said but obviously not as much as you are. At this point I decided to try my luck and said well feel free to have a go yourself if you want. She looked up at me and said really? I said yes help yourself. She smiled and stepped closer. She put her hand on my cock and started feeling it. The excitement in me was massive and she said wow that is hard. After a minute she put her fingers around my cock and started wanking me off. I stood there and said something like oh my god that's good. Without taking her eyes off my cock she said so you are enjoying this then. I said you have absolutely no idea just how good it feels to have you giving me a wank. She just smiled and carried on working my cock. I couldn't believe how good it felt having Sophie pleasuring me and after a minute or two I said I'm not going to last much longer. She looked at me and said well you better let me see you finish. She stepped back and I started wanking for her. It was actually less than a minute when I felt the pleasure building and I looked at Sophie and said ready? She said yes and was looking at my cock. I gave a loud moan as I climaxed and seeing Sophie watching me cum felt wonderful. I wanked for another minutes or so until I had completely finished. Sophie looked at me and said clever boy. Standing there completely naked in front of her was so exciting and felt fantastic. She looked me up and down and said you will let me know when you are going to be enjoying yourself again won't you. I told her that it was normally every weekend and not to worry because I will definitely let her know. Sophie said ok and left. I can't believe just how good it is having Sophie watching me and for me the weekends can't come quickly enough.
