Reading others' accounts of their first mutual masturbation reminded me of my own,
I had known Jim since we were about nine years old. He was a rather quiet, blond-headed boy who was very friendly and never gave the slightest impression that sex had ever entered his thoughts. I was surprised when one night just after my 12th birthday, while we were at the club our parents belonged to, he suddenly said, 'You jerk off with soap don't you?'
Puzzled, I stared at him without replying, and he continued saying, 'Come on, we have known each other for a long time, I jerk off, and so do you. I can tell from seeing you in the showers; your pecker head shines just like mine. That's from using soap when you jerk off.'
I admitted that I did and had been at it for four years. His next question was, 'Have you shot off yet?'
I answered that I had been shooting off for six months. By that time, we were both rock hard, and Jim suggested that we go sit in his parents' car and jerk off together.
We did; when I came, he exclaimed, 'What a load!'
Soon afterward, he orgasmed too. His ejaculation wasn't as copious as mine, but judging from his expression and shaking, it was a very good one. After the first one, we got together after school almost every day for a session.
