My aunt

She was my mother's sister, she was single and lived with her father ( my grandfather ). I was about ************ when I had a flash of her nude. That vision accompanied me during the years. We lived in different towns but I used to go to their town during my holidays. An evening, when I was 20, we were watching television on a sofa with her father. All of a sudden I began to kiss her arm. I was afraid that she would object, but she said nothing leaving me surprised. Later we went to sleep ( everyone in his own room ). After little I began to wank remembering what happened on the sofa, but in minutes my aunt entered in a transparent nightgown and asked me why I had kissed her arm. I answered telling her that at 12 I had seen her nude. We talked about that matter and she asked me if I wanted to kiss some other portions of her body. My aunt told me that during her life ( she was 61 but still gorgeous ) she had only an affair with her boss and no other adventures or men. She standing and me sitting on my bed, I began to kiss her body; she took off her nightgown and went on the bed with me. We made love for about two hours trying not to moan since my grandfather was in the next room. Still now, when I remember that night, I can't help masturbating like a fool.
