Before anyone thinks I am being abused, or harmed, let me just say that I made this happen quite intentionally and deliberately.
Background - I knew he was looking at me in a different way ever since I started to develop. Since his wife died many years ago, he has loved on his own and has been truly wonderful to me, expecially when my own mum died three years ago. My dad had a breakdown when mom died and spent several months in hospital.
Like most girls my age, I masturbate. I know that 'nice girls don't' but you know what? They do. I do. Most of us do. This particular day, I had the place to myself and decided to have some 'me' time. Since uncle Allan was out for the day, I decided that I would wander around the house naked which always turns me on and then masturbate outside by the pool. This is something I rarely get to do, but as Allan lives in the middle of nowhere, I figured what the hey.
So, there I was by the pool fingering myself to my third orgasm when I heard the pool gate go and there was my Uncle. He left immediately and walked back to the house. I felt awful, not because he had seen me, but because I knew he hadn't had any for years and it must have been truly awful for him to see me masturbating. I dressed and went to find him. He was working in the barn and I stopped him and told him how sorry I was that he caught me. In return, he said that he should have phoned first to tell me that his trip had been cancelled.
Then, bless him, he apologised again and said that he was sorry if he embarrassed me. (No, he wasn't hard, no he didn't come on to me sorry) That's when I said 'Look, it must have been very bad for you. I know you haven't had a girlfriend or anything and to see me like that... well... sorry.' He said that it was one of the most beautiful things he had ever seen, but that again, he hoped I hadn't been embarrassed. There was a huge and very awkward silence. In the end I said 'Let me help you.' He of course said no, but my mind was made up and I slipped out of the dress I was wearing and stood there totally naked. (I wasn't wearing anything underneath. I had just grabbed the dress)
Allan couldn't help but look at me and I saw him start to get hard. I walked over to him and unzipped him. His cock was massive, and I mean huge. I jacked him gently for a few minutes before starting to jack him really hard. He moaned and it was only a few seconds before he said 'I'm gonna cum Jess.' and holy shit did he cum! It seemed to go on for ever and I got totally covered. As he was cumming I reached between my own legs and rubbed myself. His sperm running down my body and between my legs felt really horny and I pushed some of it deep in me as I orgasmed on my fingers.
Allan and I did a lot more over the next few weeks that I stayed with him. Mostly stuff I am not allowed to write about here, but we had many masturbation sessions outside, and also I gave him his all time fantasy. He told me he liked the thought of a girl peeing her panties, so I did that not only for him, but ON him too.
I don't feel in any way abused, or harmed. I wanted this to happen and I am so glad it did.
