Tarzan tries to escape from the manhunt of tribal band Mangani, the great apes. They hunt Tarzan since he looks very different, white-skinned, with no fur on his body unlike the Manganis have, Gomanggani "The Great Black Apes", they really proud of their black and long fur surrounding their body. A common practice among Mangani tribes, they hunt the minority and torture the other creatures that stand in their way.
Kerchak, as the lead of the band, always hates and wants to get rid of Tarzan if he's not protected by a female Mangani named Kala (wife of Kerchack) who nursed and took care of Tarzan until he reaches adulthood, Kala just like a mother to Tarzan.
One day, Tarzan decided that he wants to prove to Kerchak, that he's one of them and willing to do anything to be accepted by the tribe. They have an ancient ritual that the leader of the band, has to copulate with the alien that wants to join their sacred band. If the alien (Tarzan) survives the copulation process, then he will be accepted by the royal bloodline into the tribe.
The sacred ritual is conducted in the holy river of Burganda, at the peak of mount Brigandina. Kerchak, who supposed to be the father of Tarzan who denied him for so long. Tarzan, who longed to be accepted by the tribe. The two meet in the arena of ritual. With the bless of holy water of Burganda, they begin to conduct the sacred copulation.
Kerchak let his long, probably 10 inches primate cock out of his furry sheath. Tarzan is shocked by how long and monster-like it appears after it is fully erected. Kerchak charged in Tarzan's direction and grab him by the head, turned his body around, and his hip start to hump Tarzan's back, his meat-rod try to aim for Tarzan's backhole.
Tarzan scream so loud anyone on the mountain of Brigandina could hear, which mean Kerchak finally had hit the mark.
Kerchak starts to hump Tarzan brutally and at a very fast pace. It was hardcore pumping and Tarzan feel like he could be torn any moment now. Kerchak now at his peak, let out a big roar so that all the other Manganis could hear that Kerchak already at his limit.
All of a sudden Kerchak stop pumping and screaming so loud a beast could ever let out. Inside his rectum, Tarzan could feel a warm liquid just flooding in no-stop, just like Kerchak is pissing inside Tarzan with his jizz. That flooding session lasts for about a minute until Kerchak let his cock out of Tarzan's hole, and surprisingly it still spurting white liquid out of his urethra.
Tarzan feels that his stomach bloated from the flood that went inside his body, yet fortunately, he passed the initiation, he smiled a little to see Kerchak defeated face, yet finally, Kerchak accepts the situation and says...
"Congratulation, my son, you are now part of Mangani"
