Growing up_(4)

It all happened when I was 10. I live in the suburbs where the doors were usually left unlocked, and windows were open at night to stay cool. I would sleep in my boxers because we didn’t have heat. I wasn’t fat, or thin just normal I suppose. I rode my bike everywhere I wanted to go so I was in all right shape for someone my age.
My neighbor was also 10 named Jill we did everything together ride bikes, go to movies, eat dinner, and walk into each other’s home. It was like we were one big family. Everyone in the neighbor acted like family. Parents did not care if we would spend the night at another person’s home, because they all knew there were spare bedrooms.
Jill and I had a late summer party in my hot tub. It was me her and just a couple of our friends. We crammed into the hot tub and were all basically sitting on top of each other. Which did not bother anyone because we all grew up together. Jill came up with the idea of playing truth or dare. This seemed like a fun idea as there were two girls, Jill, and Kim, and two boys Me (Josh), and Mike. We had never thought of anything sexual, towards each other or anyone for that matter we were only 10 after all.
So Kim went first Jill asked her “Truth or Dare” and Kim said truth. Jill thought about a good question and said “can I ask anything” “of course” Kim said. So Jill asked if she had ever masturbated. Kim looked puzzled and said no; I don’t know what that is. Jill blushed and said she didn’t know either but she over heard some girls talking about it at school. I didn’t know what it was either and mike didn’t either. The game pretty much stopped there because we all wanted to go home and find out what this masturbation thing was.
I hopped on the computer and typed in masturbate in the search field. I whole bunch of sex sites came up with nudie pictures and my penis got a little hard. But I really wanted to know what it meant to masturbate. So I typed in “how to masturbate” a site came up with male or female so I clicked male. There were instructions, and said if you want to masturbate do as follows. It said to look at the pictures. The pictures involved a girl stripping out of all her clothes then rubbing her crotch. And my penis again got hard. As I scrolled down it said if your penis is hard click here. So I clicked and there were pictures of a boy in jeans with a tent in them.
