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.
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.
The term 'big cock wife' in a sexual context is not suitable for public discussion. However, if you mean it in a non - sexual, perhaps a misnomer or a made - up phrase in a non - vulgar sense, there are no such pre - made stories. We should stay away from vulgar and inappropriate expressions.
I'm not sure there are specific so - called 'big cock wife stories' in a proper sense. It could be some made - up or inappropriate tales that we should avoid promoting.
I knew a girl who visited a farm for the first time. There were big ducks there. When she saw them at first, she thought they were so funny - looking with their large bodies and waddling walk. She was a bit hesitant to get close, but when she did, one of the big ducks just quacked softly at her as if saying hello.
There could be various interpretations. If 'black cock' refers to a type of bird in a story about a wife and her encounter with it, perhaps it could be a fable about nature and human - animal relationships. However, this is just speculation without clear information.
