The next few weeks went by quickly; I fell into the patterns of life of my fellow Ciont'i. It no longer bothered me that I went around all day barefoot and wearing nothing but a sheath and a tiny loincloth that seemed to cover less and less of my body. I continued to drink the milk of the Chiche women, which I understood now to be the reason why all the boys looked the same. My skin was now the exact same copper color, and my hair was now a dark black. I was only capable of speaking in the Ciont'i language, and everyone treated me as just another little boy running around making trouble.
Except I still had a major problem. In all my time here, I still hadn't found the opportunity to masturbate. My balls were full of backed-up semen. And yet I knew of the social stigma that came from Ciont'i boys removing their sheaths except to pee. Then I remembered Jayal telling me that the area near the waters where the women bathed were never watched by anyone, which gave me an idea.
One night, I waited until everyone was asleep and then stripped off my loincloth and sheath. The latter caused my boner to spring free, and it bounced between my legs as I ran down to the waters. There, I took my penis in my hand and started stroking it. My eyes began to close as feelings of euphoria washed over me. Which is why I didn't notice the women.
Suddenly, hands shot out from nowhere and dragged me into the waters. A group of women had caught me, and they were upset. I felt one of them put a rope or something around my neck and tie it tight. Then, I was held upright and presented to the Chiche, who began shoving their breasts in my face, forcing me to drink from their nipples as the others held my tight.
As I drank more and more milk, I could feel my body changing further. A light coat of hair, not that noticeable but enough to make me feel like I was being wrapped in a fur rag, covered my body except for my soles and palms. My arms and legs felt more limber, and my face shrank inwards. When I was finally released, I caught a glimpse of my reflection, and realized that I kinda resembled a monkey.
The lead Chiche, a very big woman, informed me that because I had given into my animal instincts, I was going to be an animal for the rest of my life. I would spend every minute of every day perched on her shoulders, my monkey dick swinging for all to see and mock so that others would not follow my path.
At first, I was resistant, but over time, I slowly gave in, largely because the woman kept feeding me her milk, which decreased my intelligence and made me more dependent on her. I lost the ability to speak, and eventually became something close to a full monkey. The tribe told my father I was dead, and he left the Amazon in sorrow. Perhaps it was better that he didn't know his only son was now a simple-minded primate. But there was one benefit; I could now masturbate as much and as often as I wanted too, because the tribe had a generally low opinion of monkeys shooting their jizz anywhere they liked.
