I spent the summer of 2003 in Africa, researching chimpanzee behavior with my mom and dad. I didn't know anything about masturbation, but I was always feeling horny and liked to rub against my sister in the tent.
One day I was out with my dad watching the chimps and taking pictures when one of the chimps began to masturbate. I thought this was weird, so I asked my dad about it. He acted surprised and then said that masturbation (first time I ever heard the word) was natural and it was fun.
We watched the chimp do it for a real long time and then one chimp tried to mount another chimp, also a male. I guess there's gay apes out there.
Anyway, then my dad told me to take off my pants, which I did. He grabbed my dick and made it go hard and then he showed me right there in the bush what masturbation was and how good it felt. I came all over him and he just smeared it in his clothes. Then he pulled out his and told me to watch. As I watched, the chimps were watching too.
My dad played with his thing a real long time and then I was hard again and I did what he did. I looked over and the chimps were all doing it. They were all masturbating! I got some good pictures, but I didn't take many because my dad grabbed my thing and made me shoot stuff all over a second time. By then, I hurt, so me and my dad sat there and watched the chimps masturbate and try to mount each other and then get into monkey fights.
