At the time this story took place I was 18. I originally come from a very remote village in the deep Amazonas.
So, in my village things where a bit different from the rest of the world. Just so you know by the way we had little to no contact with the outside world, the younger of us didn't know that there was a whole world out there, we only knew of the jungle.
The village I lived in consisted of about 50 people all living in smaller huts with their families, at least until they were considered adults which was when you turned 20 years old.
Our tradition where very strict on sexuality, we were never though sex ed. We just had to learn about it when we turned 20 and got forcefully married to a girl around the same age as you. That meant that seeing someone else naked that you weren't married to was a big no no, as was any kind of masturbation.
So now that you have some backstory to it all here is what happened.
It was a normal sunny day, I was out scouting for animals on my own, I had been sent out by my family in order to train myself to become a self-sustaining man. After about half a day without finding anything of interest I started losing hope, I had been moving further and further from the village. We weren't allowed to venture to far from the village by our self, especially before truing 20. But as I was determined to find a bigger animal to kill and bring home I pressed on.
Suddenly I heard something in the distance. It sounded like crying. I moved closer to investigate, and saw a female which looked about my age sitting leaned against a tree. She seemed to be crying, I was hesitant at first, as it seemed strange. But wanting to be helpful I inch myself closer to her. After watching for a while I eventually mustered the courage to walk up to her. I had a spear with me but as I didn't want to scare her I left in in the bush I was hiding in. When I stepped out into the open she slowly opened her eyes, looking right at me. She was beautiful, we started at each other for a little bit. Then I suddenly felt something stinging my neck, I pulled it out and saw that it a small dart. Panicked I ran back to get my spear and got into a defensive position, but I started feeling weaker and tired. I tried my best to keep awake, but eventually fell to the ground and black out.
When I woke up, I found myself tied to a table inside a dark hut. I tried to get loose but to no avail. After a while a woman walked in, she walked around inspecting me. I commanded her to release me at once, though she didn't seem to understand me. So, I again commanded her to release me. But she just stood there looking at me, without saying a word. After walking around me for a bit longer she left.
Some time passed, I don't really know how much, but it had turned dark outside by now. I was scared, but tried not showing it, as I was though that showing your fear made you weaker. After what seemed like a long time the woman from earlier entered again, but this time she had 4 strong looking women with her. The 4 strong women took positions around me, one at each of my limbs. The lead woman then started undressing me. I tried struggling but it didn't help, she was able to remove my cloths (I only had on a pair of underwear of sorts made from a crude fabric we made and some leaf's.) I was now completely naked, which was really embarrassing in front of all these women, even though I tried not showing it. The woman started inspecting my penis, looking under my balls, pulling back the foreskin.
When she was done inspecting me she took out some water and started washing it all over my body. After that was done she nodded to the other women, and they started to loosen my restraints. I thought that this was my shot at getting away, so as soon as all my limbs were free I tried rolling of the table, but was quickly stopped by the women. I was carried out the hut and into a dark smaller village. In the middle of the village there was a stone altar which was surrounded on two sides by two smaller fire trenches. There were a lot of people there, all surrounding the altar in the middle.
I was carried over to the altar and again tied up there. People started gathering around, they strange thing was, was that I only saw woman and girls around, no men at all. After I was secured to the table, the 4 women who had carried me joined the crowd. Suddenly the girl I had seen earlier in the jungle walked out of a hut. She was all naked, she was so beautiful with her long black hair, perfect figure. Up until that point I had never seen a girl naked before, especially one around my age.
She walked up to me, and stood there in front of me. Then the leader woman started talking and after giving some sort of speech the beautiful girl walked up between my spread legs. She proceeded to climb up on the altar sitting at my legs, grabbing my penis and putting some form of liquid on it. This made me get the hardest erection I had ever had, I was so embarrassing having all these girls around me while just lying there helpless and naked.
When I eventually had a full-on erection, the girl moved closer and moved my penis towards the slit between her legs. Slowly she put it inside her, it was the best thing I had ever felt. When I was all the way in she started thrusting, slowly up and down. It didn't take long before I could feel I was going to cum. I tried holding it in the best I could but I then finally came inside her. It felt so good that I felt that I had to cum again, which I did. I put another big load inside her. She seemed to enjoy it very much. As she moaned very loud. She then put her hands up in the air and everyone started cheering. I had never felt so embarrassed in my entire left. After a little while the girl stepped off me and was escorted back into the hut she came from. Shortly after that I was untied by 4 women and taken into a bamboo cage inside another hut. I was left alone. I sat there in the dark thinking about what just happened, it all seemed so unreal somehow. Eventfully though I feel asleep.
When I woke up the sun was just about to rise. I was given some food, but left in the cage the whole day. When night eventually came I was again tide up and brought outside to the middle of the village, where I saw another boy who seemed a bit older than me sitting on the stone altar tied up. He's balls where placed on another stone in front of him, and her was sobbing and I could tell her was looking very pale.
Then a girl with a really big round stomach about our age walked out of a hut, she walked up and stood behind the guy. Then the leader woman as the night before held a speech. When she was done, the girl with the big round stomach picked up a big heavy looking flat rock. They guy seemed so scared, he even desperately tried getting loose, sobbing something I didn't understand.
The girl then slammed the rock onto his balls as hard as she could. He screamed higher than I ever heard someone scream before, but after a few second, he became silent and became motionless. The girl picked the rock back up then again slammed it on his balls. But the boy remained motionless. After a third time, she lifter the rock up in the air, if was wet and had bits of what looked like meat stuck under it.
