Our parents both worked so I had to come home right after school let out to watch my little sister. At the time I was 14 and she was 10 but we got along not to bad other then she always wanted to be with me even when my friends were over. The guys bugged the shit out of me letting my kid sister hang out with us.

We were playing poker for pennies and when my sister wanted to play my best friend said that if she played it was going to be strip poker. I was shocked when she said ok. We cheated and soon had her naked and when she lost after that we would get to touch her or she would have to jack our cocks for so many minutes. That's how it started for my sister and me but after some stuff got broke no one was to be in the house other then my sister and me without our parents being home.

We still got naked and played with each other but when I heard about going down on and girl things changed. Val would go nuts as I licked her little clit, she would suck on my cock but the first I cum in her mouth she didn't want to do it anymore. We started doing what we called the slide game where I would be on my back and sister would slide her pussy back and forth on my cock. We found using baby oil when we did this to work well We both would do it until we both got off.

I remember when my sister was 11 her nipples began to grow and she got her first few hairs on her pussy. I knew we had to be careful cause she would be a woman in no time and she could get pregnant. One day as we played our game I started playing with her nipples and she went totally nuts and moved to far up and then pushed down hard. Before I could stop her I was halfway inside her and she screamed loudly. I was scare and tried to pull out but she yelled at me to stop cause it hurt to bad.

After a couple minutes I guessed her legs were getting sore cause she sat down more and more until I was all the way inside her. She kissed me on my lips saying go slow please it still hurts a bit but it feels wonderful. That was the first time we fully fucked. After that we only fully fucked when I could find condoms cause back in the 60s they were not easy to get for a 15 year old.

I got married first but still fucked my sister every chance we got, that is until my wife caught us and clean me out in court. When my sister got married we still fucked every chance and when she give birth to her first child we were pretty sure it was mine and not her husbands as the nine months before he was out of town for two weeks. She told him she give birth a little early.

She told we they had a huge fight and that's when she told him the kid was mine and not his. Well her and the kid got their asses kicked out of the house and she moved in with me. She went back to her maiden name and we had two more kids as husband and wife but just not married.

Our daughter who was first born is married with twins who are in their early teens but a boy and a girl. Our daughter come to us all worried cause she saw them having oral sex with each other in the basement. She asked us what she should do and I give her a box of condoms the give her son saying they wont stop once they start. Winking at my sister.
