Robert and Eve were twins, the children of a teacher and a University Professor. They had fought and played together all their lives and supported one another through each of their teenage troubles. They were very close, so it was no surprise to see that they were both drawn to the same interests including an abiding interest in Anthropology.
The twins attended the same University.
Having spent a number of years working various field trips around the world, the twins had decided to organise their own trip. Robert had picked up a whisper on their last trip, regarding a lost Amazonian tribe deep in the furthest regions of the jungle.
Having gained approval for the expedition from their backers, the pair set to arranging equipment and staff and their travel to the lower branch of the Maranon River where they made their home base.
It was 15 days into the expedition when porters and other staff began to disappear. It was clear that something was frightening them. Robert called a halt to their advance and set up camp to discuss the way forward. It was clear from their Interpreter, Raphael that the expedition had effectively ended. He suggested that they spend a final night in camp, before packing limited supplies and returning to base on the morrow.
Eve was awoken by the sound of a scuffle outside her tent and lighting her torch, left her tent to establish its source. Within seconds, she was surrounded by a large group of partly clothed Indians who hustled her over to where her Brother Robert and Raphael were already standing.
"For Christ's sake Raphael, what the hell is going on?" Said Eve.
"It would appear that our guards and the last of the porters have abandoned us to our fate. I don't speak their language, but it is close enough to others for me to make out basic ideas. It seems they have been following us for some time and have it in mind that both you and Robert have been sent from the Gods."
"In that case, tell them to release us and let us go our way."
"It's not that easy," said Raphael. "They have some sort of ceremony due and believe that you both were sent as messengers from the gods to take part in it."
"Oh Shit." said Robert. "What sort of ceremony? Please tell me they are not cannibals?"
"I'm sure they are not," he replied. "From what I can understand, it is some sort of fertility ceremony, calling down the gods to bring food and rains to grow their crops. Right now, they clearly require us to follow them back to their village. I might also advise you not to argue with them, or give them any reason to lose their temper. "
It was no more than a mile or two to the camp, where on their arrival; Robert and Eve were separated and taken to separate huts.
On entering her hut, Eve was confronted by a half dozen female Indians, all of whom were totally naked. Within seconds, Eve was also naked having been stripped by the other women and was placed into some form of throne. Once she was sitting in her seat, she was approached by an old crone carrying a gourd of some kind. It was clear from her gestures that she wished Eve to drink its contents. Reluctantly, Eve brought the gourd to her lips and was surprised by the sweet smelling concoction. The liquid was warm and sweet on her lips and slipped easily down her throat, exploding in her stomach and raising her temperature. Within a few minutes, the heat began to work its way down to her genitals and out to her nipples, her libido exploded and her pussy began to leak. The women took hold of Eve and raised her to her feet before beginning to oil the whole of her body, their slippery hands left no part of her un-oiled, slowly massaging her breasts, buttocks and vagina. Their oiled massage drove Eve's sex drive through the roof, she found herself moaning in frustration, not being permitted to stroke herself. Her needs rose with the beat of the drums she could hear outside the hut.
Eve shivered as she was led out into the cold night air placed in the seat to the left of the Chieftain's chair. Her naked, oiled body glistened in the dancing light from the many fires around the clearing. The sound of the drummers beating the logs took on an almost hypnotising effect.
Hearing a scuffling to her right, Eve looked to see her brother being led out to the chief's Dias, being placed into a seat on his right. She saw that like her, his body had been oiled until it shone like a highly polished stone. She noted that his body was well defined with the muscles rippling under his dark suntanned skin. She could hardly withhold her gasp as her eyes fell to the appendage between his thighs. Robert's penis was slightly turgid and hung heavily along with the sac containing his balls. Eve saw that it must be at least eight inches in length and appeared to be more than two inches in breadth. Eve was shocked to see that Robert was making no attempt to cover himself up. If anything he seemed to swagger. Seeing Robert's genitalia brought her mind back to her own body. She noted that her nipples were swollen and erect and her breasts throbbed. She could feel moistness between her thighs, where for some reason; her kegel muscles were softly pulsing.
Looking around the clearing she counted twenty or more fires. In between and around the fires were many rugs. In the centre of the circle was a large heap of skins surrounded by a row of small bowls in which wicks were slowly burning. She could hear a low chanting from somewhere behind her slowly rising in volume.
Looking to her left, she saw Raphael standing on the edge of the clearing and beckoned him over.
"What's going?" She said.
"I understand it is a fertility ceremony, calling on the Gods to provide good crops and lots of children in the forthcoming year. They will praise the Gods with their bodies before calling on the God's messengers, that is, you and Robert, to procreate and bring in the new year of plenty."
"What! Myself and Robert to do what? They want us to fuck for them?"
"These people see you as messengers of their God. They want you to offer your bodies as a conduit for his beneficence. By having sex, you open the path from yourself to him. The more sex, the stronger the connection, the greater the benefit."
"Raphael, Robert's my brother. I can't have sex with him for heaven's sake, and what do you mean by 'the more sex'?"
"I tried speaking to their Shaman to get him to work out some other way of calling down their God, but he's adamant you were both sent to call down their God. As for the other matter, I suspect they will expect you both to have sex for the whole of the ceremony."
"I'm not doing it Raphael; I am not going to fuck my own brother, and certainly not in front of the whole tribe."
"Then it's very likely you will both die. If you are not as they believe, messengers of their God, then you have been sent by their enemies to cast bad magic on them."
"Tell them the truth. This is ridiculous, we can't do it."
"Oh you will," said Raphael. "I think you will find you have no problem doing it when the time comes. After all, you have all the help you need."
"What?"
"The drink you were enjoying whilst they massaged you is a potent aphrodisiac and will supply you with the urge you will both need when the time comes to begin the ceremony."
Eve saw the smile cross his face and followed his gaze down to her breasts, where she saw her nipples were now fully engorged. She thought she saw movement, as though each nipple was pulsing to the incessant beating of the drummers. Her breasts felt full and heavy, heat inside them increasing.
Suddenly, Eve felt the Chieftain tugging at her elbow. Turning, she saw him pointing across the clearing to where she saw two lines of people, one male and one female. Both lines were dancing and swaying to the hypnotic thumping of the drums. All of them were naked, their bodies heavily oiled and their skin reflected the light from the various fires.
The lines began to weave in amongst the flames. In the light, Eve could see that all of the dancers were young, probably the fittest of the tribe. The women's breasts were quite small, but their nipples were long and heavily swollen. All had child bearing hips and a forest of tight black hair at the juncture of their loins.
The men's small but muscled bodies rippled in the dancing light and caused Eve to gasp, as she saw each throbbing erection protruding from the mat of black hair between their legs.
In and out and around the fires the dancers stepped. Soon it became clear that they were beginning to pair up. Before long, each of the women held a man by his penis and led him around whilst at the same time, stroking his length. Slowly, each couple danced their way to one of the mats set out in the circle where they stood facing each other.
