When I was around 12 or 13 years old I would always change into shorts with no underpants on when my sister's friends came over. I would get a boner then lay on the couch, on my side, with one leg up so they could see my erect tween dong!
I would watch them to see if they were looking but not directly. I used my peripheral vision to keep tabs on their gazes. This one girl tiffany would look at it like like every 10 seconds. Whenever she looked at it I got even harder.
She would spend the night all the time and we'd stay up late. One time we were watching a movie and we were all under the blankets together (it was winter). Naturally I was free balling in shorts again. I positioned myself so that if I got hard it would touch her thigh.
Then I started thinking the sexiest thoughts that a kid that age could think of. I could feel my bone growing and reaching out towards her leg. Finally the tip made contact with her thigh and she moved it away. I moved ever so slightly. I mean you could hardly tell I had moved at all and it was touching her again. She moved again. I was devastated and had pretty much given up.
I went back to watching the movie. About 15 minutes later she rolled over so that her body was facing mine. She moved her hands forward underneath the blankets and accidentally touched my cock. Then something amazing happened! And now i can talk to animals! It's really cool!! but a complete secret... and you know what? Life's never been the same!
