Brother & Sister Put on a Show

My introduction to jerking off and sex between brother & sister

When I was about 10, my parents were going through a rough patch and me and my mother moved in with my grandmother on a farm. I was sent to hang out with kids at another farm about 2 miles away. There was a serial vibe in this house, moreso than anything I'd been exposed to prior.
There were 3 boys there and a 10 year old sister named Irene. I hung around with John, he was closest to my age, he was 13. One day we were in the hay loft and he said I want to show you something. He pulled out his cock and started rubbing it, he told me try it with mine, I did, though I had no idea why were were doing this, then he said, close your eyes and think of Irene. Now this really made no sense to me, but I was enjoying jerking off, so I continued. That was the 1st orgasm I remember and I've been a chronic materbater since!
A few days later John, Irene and I were the only ones home. John said he had a job for me. The three of us walked into the ground floor front bedroom. He told me his mother had went to town and for me to watch out the front window in case she came back. Irene was wearing a green and white checkered summer dress. She got on the bed, lay down and pulled up her dress, she wasn't wearing any underwear, this is the first time I saw a pussy! It was a lovely smooth mound, hairless, and had a nice tight crack. John pulled out his hard cock and got on top of her, he was really pounding that thing into her! I thought to myself, this isn't the first time for them and wondered if any of the other brothers were doing her. They moaned as john shot his load in her, he got off her and said to me, you wanna go? I did, but before I could speak Irene shouted no John! Then I just said no too, don't no why , I guess her reaction through me. I've regretted that ever since, what a great start that would have been.
