I am imagining an alternate universe Earth for this where werewolves are the dominant species and they like things the old way, when the world was simple, before steam and electricity. Humans live in small villages now, each village having one Alpha werewolf and his family residing in a grand house to oversee everything and keep the humans in check.
It is coming time for a tradition that werewolves hold most sacred... for you see, no one knows why, but werewolves have only ever been born male and thus, they must seek out females of other compatible species for their mates... and there are none more compatible than human females...
The tradition is a very special ceremony, a hunt of sorts... young virile werewolf males love nothing more than to show off to their prospective mate and what better to way to do that than to hunt her down and exert his dominance over her?
It has become custom over the last couple of centuries that every year, when werewolf males come of age to take a life partner... the matching amount of untouched females anywhere from eighteen to twenty from the villages are rounded up and taken to a huge deep stretch of forest that is most sacred to the werewolves... the girls are then ordered to run into the forest, promised that if they elude capture, they will not have to submit to a werewolf husband this year...
Then, after the girls are given a fifteen minute headstart, the eager males are let loose... and the hunt for their desired female begins...
Should another male desire the same female, combat is allowed and even encouraged, only the strong are worthy to claim a mate and produce progeny...
Sex in his werewolf form is not required, I just thought the picture set the right kind of mood for the story.
