When I was eleven, I was hanging around in the neighbourhood with two boys from my class. We walked a lot and finally reached a lake, where in the summer we swam very often. After quite a long time chatting at the side of the lake, someone came up with the idea to go swimming. Because no one had taken swimwear, we decided that we had to go swimming in our underwear. At that age I thought it wouldn't be a problem. I already had a little breast growth, but they were still very small, I didn't think of it at that moment. In only our underpants we went swimming for a while. We had a lot of fun.
After a while, we quit swimming and rested at the side of the lake. After talking for a couple of minutes I noticed that Tom and Kevin kept their eyes at my crotch very often. Through the wetness of the water, my underwear had become transparent and they actually could see right through the material: they saw nearly everything! But then, as I looked at the boys crotches, I noticed that their underwear had become wet and transparent too! We all felt a little ashamed, but couldn't help laughing. 'After this, we can swim in the nude,' Tom said, 'It doesn't matter now.' We laughed but did not swim again, because the water was a little cold. Because our underpants would dry faster taken off instead of dressed, we decided to undress completely. It was the first time in my life that I saw nude boys and I found it quite exciting. After some silence, looking at each other and exploring each other with our eyes, Tom suddenly asked Kevin 'Do you masturbate?' Kevin became really red and ashamed. Tom said 'I do', He asked if we wanted to see, and he took his already stiffened, hairless penis in his hand and moved it back and forward. Kevin's penis became stiff very soon and I giggled a little at the sight of it. Kevin started to stroke his penis too. No one said a word, but it was a wonderful sight. Two twelve-year-old boys masturbating in front of me!
The boys didn't come. I mean that I saw no sperm that afternoon. Then Tom asked me if I ever masturbated or caressed myself. I said yes and they said they wanted me to show them. I have seen them, now they want to see me and everything between my legs!! I spread my legs and let them watch. The two boys looked breathless. I also didn't come before their eyes, because after a couple of minutes we heard some people in the forest nearby. We dressed very quickly and left. Later on that day, at home I undressed completely and masturbated further. I thought of Tom and Kevin and what we experienced in the forest near the lake. It felt great. I wish they were with me when I did it.
It was a wonderful memory.
