So I guess the previously posted Innuit story about incestuous-lesbianism is actually the rule rather than the exception. I give you:
'Tuglik and Her Grandmother'
(Courtesy of magpiemagpie.tumblr.com)
Once there was a big narwhal hunt to which everyone went but an old woman named Tuglik and her granddaughter Qujapik. The two of them were getting rather hungry, but they hadn't any idea of how to hunt for their food. Yet old Tuglik knew a few magical words, which she uttered during a trance. All of a sudden she changed into a man. She had a seal-bone for a penis and chunk of matak for testicles. Her vagina became a sledge.
