Brother in Law

I was 11 years old and one time I was staying with my sister and her husband for the summer. I was in the bath tub and my brother-in-law came in the bathroom to pee. I saw how big he was, my first time seeing a man's Dick. I just stared at it. He smiled and left.

A day or two later I went to the post office with him. He said 'I saw you looking at my thing the other night, some day your's will look the same. I looked at your's, it wont be long until you will begin to grow and cum'. I said 'Whats cum'? He said, 'I thought you would have heard about that in school by now. It's stuff that makes babies when you do it with a girl'. 'Oh semen' I said. 'Yeh, judging by your size it won't be long until you do it'. I said, 'Do what?'. 'Cum, do you ever play with your peter'? I said 'I tickle it sometimes when I pee.'

He said, 'If you promise not to tell anybody I'll tell you how to play with it'. 'Ok' I said. 'Give me your finger'. He cupped his hand over my finger and said 'You hold it in your hand like this and pump up and down like this'. I was hard and I could see he was too.

He pulled down a little road and stopped. He said, 'Can you keep a secret?' I said 'yes', he said 'Promise me don't ever tell anybody about this'. 'Ok what?'. He unzipped and pulled his seven inches out and started pumping it. 'This is how, you can if you want'. So I jacked off the first time. I asked him 'Can I touch yours?' He said 'Jack me off', breathing heavy.

So I did him while he pumped my little three incher. I had my first dry cum. He had a big wet one all over his pants, my hand and the car. We sat quiet until he got his breath back.

From that time on I have jacked every day. My brother-in-law never said another word about it. He caught me jacking when I was 14, I was hoping he would stay and watch me cum or offer a hand, he just said 'Sorry', and walked out.
