A survivor from a ship wreck found himself on an unknown island. Away from home, family, friends and any help, he decided to walk around and hopefully find shelter and food.
But as he traversed the unknown land, he fell into a pit. Disguised and clearly man made - a trap. Finding that there was no way out, the man settled on waiting. And not long he was found by people - obviously a local tribe.
They offered him a choice "Death or makumba?" they said. The man didn't know what "makumba" was but obviously didn't like the other option, so "Makumba." he chose. "Makumba. Makumba." the savages started chanting. The largest and the most...well endowed tribesman then proceeded to make love to him. The survivor wasn't thrilled but reminded himself that it's better than death.
After the act, he was let out to roam the island again. Not long after, he fell into another trap. The savages found him again and gave him the same choice as before "Death or makumba?". Not happy about it, the man chose makumba again repeating to himself that it was better than dying. Again the chants "Makumba. Makumba." accompanied the act.
So set free upon the island for the third time, our protagonist decided to be very careful where he went. But alas, he fell into another trap. Getting desperate enough now, when presented with the familiar choice of "Death or makumba", he chose the former. Everybody started chanting "Death through makumba. Death through makumba."
