This happened last night. It all started off my best friend (13) and I decided to play truth or dare. It was mostly truth, though. We started off with girls, and who hade the best body, etc.
After a while we started to run out of questions for that type of stuff, so we started talking about jacking off. My friend said that he had just started to masturbate, only about seven months ago. (I've been doing it since I was just turning 12.) Well we started talking about technique and what we fantasize about. But after a while that got boring too, so we started asking questions about who we would mutually jack-off with, and when we'd do it. It was basically us asking each other if we wanted to watch each other.
In the end, my friend said that he was going to jack off and, if I wanted to, I could, too. Well, we turned on the light, and his dick was already rock hard, as was mine. He sat down in the chair and started to play with his head, then his shaft, in total 6'.
I was just in my boxers and had started right after him, I had already started to jack when we had first brought up the subject. I have a bit larger dick 7', probably because i'm older. I came first, and it went all over me. He came a bit later, he was looking right at my dick the whole time. He was still not cumimng yet.
We both ended up doing once more that night, but it was already two in the morning. That was definitley a fun thing, and I'm sure we'll do it again.
