This all happened when I was 11 years old, my brother was out on the hammock. After I decided to join him, he seemed quite startled. It was then that I noticed he had the little portable back massager in his hand, and he seemed quite embarrassed.
'What were you doing' I asked. He replied nothing, looking away and acting ashamed. Then he asked me if I wanted to try something new. I said ok, not knowing what he had in mind.
All of a sudden he put the vibrator right on my crotch and turned it on. Immediately I went to move his hand, but he persuaded me to just try it. At first I didn't notice much, but then it started to feel kinda tingly. He started pushing it in harder and rubbing it up and down. The tingly sensation only got more intense, but now it felt even better, a new feeling I had never felt before.
'Do you like that?' he asked. I replied yes. Then I told him I think I have to pee. He told me to just let it out, I won't pee no matter how much it feels like that. Now I could really feel it, I had to pee sooo bad and it just kept getting more and more intense, but surprisingly I didn't, and now it was feeling so good I started to rock my hips a little bit. All of a sudden the feeling went away, I thought it was over until I started to feel something else. He sensed this and pushing it into me even harder, knowing what was going to happen. This new feeling became more apparent, I had never felt it before. It just kept getting better, I started to close my eyes and smile, laughing almost. My hips were really going now, I couldn't take it anymore. I just kept getting better.
'Stop please' I asked him 'It's too much, please stoooop!'
But he kept it on hard, I couldn't believe how good it felt. I was squirming like crazy, I couldn't take it anymore. All of a sudden I felt a surge of energy go through me and I let out a little yelp, oh my gosh that felt so good, these little rhythmic contractions that lasted for about 10 seconds. Soon it started to hurt, so I told him to take it off.
When I was done, I couldn't believe what had just happened. All I knew was that it felt really really good. I visited him on that hammock later that day as well.
