After a moment the tribal chief shouts "Mapata! It is time!" You find yourself forced to turn around, and notice that the other tribes have left. "The ritual begins now!" he continues, and you lay yourself back down on the rock slab, awaiting in trepidation what is coming next.
"Now we make our fountain!" he cries, and without warning dozens of tribesmen leap on top of you at once, and begin vigorously fucking the obsidian studs. You become horrified as they thrust their miniature, but still considerable penises in and out, in and out--but despite your horror, you feel yourself becoming aroused as their bodies writhe against your thick muscles. You feel one tribesman thrusting into each of your ears...you watch others thrust into the studs where your nipples once were, where your belly button was, and at regular intervals down your legs and arms. As they all begin to come you can almost feel the cum surging through you, and your cock begins to rise and elongate, growing to a monstrous fourteen erect inches. The horniness becomes unbearable as the two fucking your nipples begin to grope and knead at your chest, and suddenly your penis erupts in orgasm, vast amounts of cum pouring from it.
"Don't stop!" cries the tribal leader, "He is the chosen one! The ritual must continue!" Your orgasm continues, and while the cum pours from your penis you watch in amazement as each individual puddle of cum on the ground begins to form into a new, tiny tribesman. Suddenly you understand: you are their god, you perpetuate their tribe.
But at that moment a strange urge comes over you, and you find yourself struggling to your feet. The tribesman cling to you like mountaineers to a cliff, and you continue to orgasm, but something feels...strange. You grab at your ass just in time to feel some sort of appendages emerging from each cheek. Within thirty seconds they grow into a matching pair of legs opposite to your normal ones. Still in shock, you feel more appendages emerging, this time from your torso. These grow into another set of massive arms, set just below your old ones. New obsidian studs emerge on the surfaces of all these limbs, and the new tribesman, newly formed from your cum, eagerly leap up and begin thrusting into them. You moan as your pleasure multiplies, and then--
"AHHHH" you roar in a rumbling baritone that shakes the trees, as a new wave of orgasm unlike any pleasure you've felt before hits you, and looking down you realize that a new dick has formed between each of your legs--three new penises, each as enormous as your original one, each one ejaculating wildly. As drops of cum turn to foot-high, muscular tribesman, the chief shouts joyfully, "He is the chosen one! He is the greatest of gods! Soon our people will number in the hundreds!"
You continue to moan, but the ritual proceeds for what seems like hours, and teeming masses of tribesman begin to surround you as you endlessly cum...
