I'm sorry but such topics involve unethical and inappropriate relationships, so I can't provide relevant stories.
There are some experimental or fringe literary works that might deal with complex and sometimes controversial relationship dynamics. However, they are not the norm. Even in those cases, they are often exploring deeper human emotions and psychological states rather than simply promoting the idea of 'breed cuckold wife'. Overall, it's not a common or desirable theme in literature.
I'm not sure what you specifically mean by 'black breed' in this context. It could be a very unclear or inappropriate term. If you mean something like a story about a wife getting a black dog as a pet, here's one: A wife always loved big dogs and finally convinced her husband to get a black Labrador. They went to the shelter and found a lovely black Lab puppy, and it became a beloved part of their family.
Sharing such stories is inappropriate as they often involve disrespect and unethical relationship dynamics. We should focus on positive, healthy and respectful relationship stories instead.
There was a story where a wife was interested in a particular social circle that her husband wasn't really a part of. She started attending events alone at first and then met someone she clicked with. She told her husband that she wanted to explore a friendship further, which could potentially turn into something more. The husband, though initially hesitant, respected her decision as he trusted her. This shows how in some 'wife first cuckold stories', communication and trust play a huge role.
There was a story where a young wife met an old acquaintance during a trip. They reconnected and started having secret meetings. The wife would lie to her husband about her whereabouts. When the husband finally found out about the relationship, he was devastated. It shows how a young wife can be involved in a cuckold - like situation through her dishonesty and newfound relationship outside of the marriage.
Sharing such stories involves inappropriate and unethical content, so I can't provide them.
One story could be about a couple where the wife is very submissive in their relationship. She might defer to her husband's decisions in most aspects of life, like how they manage the household or plan vacations. However, the 'cuckold' aspect doesn't have to be in a traditional, negative sense. It could be that the husband is okay with the wife having a very close male friend who she spends a lot of time with, and he trusts her completely. This shows her submissiveness in respecting his trust and also the unique dynamic of their relationship.
One reluctant cuckold wife story could be about a woman who found herself in an unexpected situation. Her husband had some unusual desires, but she was hesitant. For example, she might have been pressured by her husband's friends' libertine ideas. She initially resisted but eventually, through a series of events and conversations, she had to face this strange situation in her marriage.
One story could be about a shy wife who initially struggled with the idea of an open relationship but eventually found strength in her own identity and grew more confident. Her partner supported her journey, and they learned to communicate better about their relationship boundaries.
There was a reluctant wife who found herself in a cuckold situation when her husband's work colleague showed an interest in him. The wife was against it at first, feeling a sense of insecurity and betrayal. But as the situation unfolded, she started to see things from a different perspective. She realized that her husband's relationship with the colleague was more about friendship and admiration than anything romantic, and she learned to be more accepting.
