When I was seven, an older neighbor boy came over to babysit while my parents were out to dinner. After they left, he started talking about having sex with a girl from school. Thinking back now, I don't think he'd ever done it. I told him about my brother's collection of dirty magazines, and he demanded to see them. I went to my brother's room and got him a few of them. He started flipping through them, then unzipped his pants and started playing with his dick.
I was fascinated, especially by the size of it. I asked him if I could put my hand around it, and he let me. It was so big my fingers wouldn't go all the way around it..(He was 16). I asked him why he was rubbing his dick, but I don't remember what he told me. I sat on the floor in front of him with my pants down, and tried to imitate him. I couldn't put my hand around my little dick because it was too small, so I grabbed it with my palm facing downward and worked it up and down.
I started getting a good feeling in my little boner, like the feeling I got sometimes when I did pull-ups on the jungle gym at school. I started pumping faster, and had an almost immediate orgasm, with my little legs flapping to squeeze out the good feeling. The palm of my hand sent a jolt through me every time it hit the head of my dick.
My babysitter adjourned to the bathroom, and must have finished himself off there. He never touched me, and we never talked about it after that. I'll always be grateful to him...
