A piece of animal sex

I happened to hear a story of animal sex in Penan society.   An old hunter gained a wild boar in the jungle.  When he walked down from the jungle mountain, he met a younger member of his family. The young boy proposed to bring the wild boar down.  He ran down with the game animal.  When an old man reached a certain place he found the boy committing sexual intercourse with the female wild boar (kunyi mere mabui)!, without noticing the old man coming by.  This is only one story of animal sex I heard from Penan.  My supposition is that this story suggested potenciality of animal sex in Penan society.
