10 yo boys birthday party

When I was 10 I went to another boys birthday party. His name was Matt and there were about 10 of us there, all boys. Matt’s parents had converted their attic into a giant play room for him so we spent a lot of the afternoon up there. His parents had put out all kinds of snacks and drinks for everybody up there.
At some point one of the boys, Liam said we should all compare our dicks and measure them. All of us puled down our pants and Matt got a ruler from his desk and we took turns to measure our own dick. One kid, Simon had the smallest dick of all of us. It was tiny and he was very embarrassed. Anyway during this measuring, quite a few of the boys got hard. We were all laughing and being kids but then two of them were waving their dicks at each other and then started to play with each other. The others were watching and soon everybody got boners. Now there were 10 boys with hard dicks all comparing and playing with themselves. Even thought that kid Simon’s dick was hard it was still tiny. Each one of us had to go touch it and play with it. The rest of us were all pretty similar in size. There was a lot of interest in the boys who were not circumcised (most of us were) so we watched as they pulled back on their foreskins to show the heads of their dicks. There was a lot of laughing and touching and then one boy David starts telling how he plays with his every day and it feels so good. There was a lot of agreement that most of us did the same. The birthday boy Matt asked if anyone wanted to play with his. I said I would and went by him and played with his. He in turn took mine and began to wank it. It felt really good. The others all joined in and paired up and played with each other. However there was a lot of interest in Simon cause his was so small. Every one of us had a turn at wanking him and he was loving the attention. Anyway over the next half our we all had a turn and wanking a different boy and eventually we all came even though nobody could produce any sperm. But Matt did have some pre cum on his dick which was. a source of fascination for everyone else as none of us knew what it was. We all put our shorts back on and started to do other things for the rest of the party. It was just kids being kids I guess.
Anyway a couple of week later I went back to Matts for a weekend and the first thing we did when I got there was go up to his attic and give each other a wank. Something we did multiple times over that weekend!
