The value of transgressive stories

What is the value of transgressive stories? Here's one: 

The Woodsman's First Tale, from The Book of Lost Things, by John Connelly, pg. 87.

"Once upon a time there was a girl who lived on the outskirts of the forest. She was lively and bright, and she wore a red cloak, for that way if she ever went astray she could easily be found, since a red cloud would always stand out against the trees and bushes. As the years went by, and she became more woman than girl, she grew more and more beautiful. Many men wanted her for their bride, but she turned them all down. None was good enough for her, for she was cleverer than every man she met and they presented no challenge for her. 

Her grandmother lived in a cottage in the forest, and the girl would visit her often, bringing her baskets of bread and meat and staying with her for a time. While her grandmother slept, the girl in red would wander among the trees, tasting the wild berries and strange fruits of the woods. One day, as she walked in a dark grove, a wolf came. it was wary of her and tried to pass without being seen, but the girl's senses were too acute. She saw the world, and she looked into its eyes and fell in love with the strangeness of it. when it turned away, she followed it, traveling deeper into the forest than she had ever done before. The wolf tried to lose her in places where there were no trail to follow, no paths to be seen, but the girl was too quick for it, and mile after mile the chase continued. At last, the wolf grew weary of the pursuit, and it turned to face her. It bared its fangs and growled a warning, but she was not afraid. 

"Lovely wolf", she whispered. "You have nothing to fear from me."

She reached out her hand and placed it upon the wolf's head. She ran her fingers through its fur and calmed it. And the world saw what beautiful eyes she had (all the better to see him with) and what gentle hands (all the better to stroke him with) and what soft red lips (all the better to taste him with). The girl leaned forward, and she kissed the wolf..."

What is the value of transgressive stories? In short, they make us sure that everything is going to be ok. It's not the contrast between those actions in the story and our own that animate us, but, notwithstanding the shock that we could think these things too, it's the understanding that we are more than the stories that make us up. In this story it is the infusion of natural-ness that makes it assuring to our psyche. It's that we are not trapped into being human beings in social strictures all the time, but are capable of human things; that, and animal things too, that more than doubles our (human) potential.
