There isn't enough information in 'wife big black' to create a detailed story. If 'big black' is a name or a characteristic like a big black dog that is part of the wife's story, we need more details. For example, is it about a wife who has a big black dog and their adventures together? Or something else entirely?
The 'big black cock' might be a symbol in this story. The 'wolf wife' could be a lonely being in a world full of secrets. Maybe the 'big black cock' is a messenger from another realm. They interact in a series of events that ultimately lead to the 'wolf wife' finding her true place in the world. Their story could be about self - discovery and the power of unexpected friendships.
In most modern societies, sharing a wife is completely unethical and goes against the principles of monogamy and respect for marriage. There is no culture that would officially support such a practice. It violates the basic rights and dignity of the individuals involved, especially the wife. In Western cultures, marriage is seen as a union between two consenting adults, and any form of non - consensual sharing is unacceptable.
I'm not aware of any specific 'big black cocks wife stories' in mainstream literature. Most literature focuses on more positive, ethical and diverse themes rather than something that might be misconstrued in this way.
There is no common or widely - known folktale specifically about a 'big black cock' and a 'wolf wife' in traditional folklore. This seems like a very unique and perhaps made - up combination that is not part of the mainstream folktale cannon.
