It happened in the summer goning into sixth grade, so i guess i was about eleven. I was and still am pretty developed for my age. My friend and i went to the same camp and we had to get changed in a seperate room, just the two of us. He is a year younger than me, so we didn't really know anything about this subject. We were playing this game where anything you touch with your dick became "yours", like if he were to touch a chair, i wouldn't be able to sit in it. So after experimenting with how the different fabrics and surfaces felt on our cocks, we decided this was a very enjoyable game! I went home one day after this and proceded to make most things in my room "mine". As I was rubbing my dick on a stuffed dog, i thought it felt pretty good, so i layed on my bed and rubbed the furry stuffed dog against my cock. after doing that for a little bit, i felt and odd sensation and moved the dog away to see my throbbing dick and watch myself cum. I already knew what it was, so i as pretty excited. from then, i would rub my dick on stuffed animals and sheets, until for some reason, i began to jack-off the average way. I still like to experiment with that stuffed dog though!
