I think I was about 14 or so. My girl cousin, a year older. I am a male, and when my uncle got sick, they moved in with us. It was very crowded, so my dad, a carpenter, bought this large lot, the house there had burned down two years before. My older brother and I helped dad clean up the place, and over the next 8 months, built a new house, 6 bedrooms, and nice but not fancy. We all moved in, and my bedroom was next to my cousin Peggy. Although she was one year older then me, we were in the same grade, and about the same size, and I really wanted to see her naked. I had a access panel in the top of my closet to the attic. I had placed 4 of those eye things that you have in the fromt door to see who is outside in the celing of her room, so now I could get up into the attic, and look through them down into her room. One night, I heard her in her room, and quitely went up into the attic, and started looking down to see what I could see. What a surprise, I looked down through the one over her bed, and there was my cousin Peggy, naked as the day she was boorn, and on top of her naked too, and fucking her was my dad.

Next day, I told her what I saw, she turned red, and asked me not to tell. I said OK, but it will cost you. After that, we fucked two or three times a week, and so did my dad. My dad never found out that we were fucking, and Peggy liked it that way. She told me that she could not tell the difference between our dicks, as we were both about the same size, 8 inches or so. Peggy got married 4 years after all this started, and has 3 girls now. I'm not sure but I think the oldest one is my dad's or mine. We both fucked her, 2 days in a row when she concived. Of course her now husband thinks it is his, so we let him think that.
