In a story, the bbw wife could be very affectionate and motherly. She would care for her husband deeply while also being independent. Her size might symbolize her strength and presence in the relationship. The cuckold husband could be gentle and kind - hearted. He may not mind his wife being more in the spotlight. He would be the one to support her from behind, like when she wants to host big parties or engage in community activities.
The bbw wife might be confident, warm - hearted and dominant in the relationship. She could be the one who takes charge of social situations and family matters. The big cuckold husband may be more laid - back, a bit naive perhaps. He might trust his wife completely and be okay with her taking the lead in many aspects of their life.
Once upon a time, there was a bbw wife named Mary and her husband Tom, who was a big cuckold. Mary was a confident and loving woman. One day, she decided to plan a big surprise for Tom. She invited all of their friends to a party at their house without Tom knowing. When Tom came home, he was shocked but also very happy to see everyone. Mary had cooked all of his favorite foods and they had a great time that night. It was a story of love and acceptance in their unique relationship.
Well, it could be that the bbw (big beautiful woman) wife is very confident and assertive. She might start taking charge in the relationship more, making decisions that her big cuckold husband initially resists but then comes to accept. For example, she could decide on a big career move for the family and the husband has to follow along.
The story could end happily if they both grow from their experiences. The wife learns to be more considerate of the husband's feelings while still being in charge, and the husband becomes more confident in his own right. They might find a balance that suits them both, like sharing responsibilities in a new way that they both enjoy.
One reason could be her loyalty to her husband. She may truly love him and the idea of being unfaithful in such a way goes against her moral and emotional commitment. In many relationships, loyalty is a fundamental value, and she might not want to break that trust.
Another reason might be that she has grown apart from her husband in terms of interests. Say the husband is into sports all the time and the wife is interested in art. If they don't find common ground, she may be attracted to someone who shares her artistic interests. Also, unresolved conflicts in the marriage can lead to this situation. If they keep having the same arguments and there's no resolution, it can push the wife away.
I don't think they are common. Cuckold relationships in general are not mainstream, and when you add the factor of the wife being a bbw (big beautiful woman), it narrows down the scope even more. Most people tend to have more traditional relationship models, so these stories are more of an outlier.
She might make a rule about him being more open to her having male friends. For example, he has to be okay with her going out for coffee with a male colleague without getting jealous.
Loneliness is a big factor. When the husband is away on military duties for a long time, the wife may feel extremely alone and seek company elsewhere.
No, they are not that common in mainstream literature. Mainstream literature usually focuses on more traditional relationship models and themes. However, in some niche or erotica - related literature, you might find such stories.
Communication can be really difficult. The husband, wife and the new partner need to be extremely clear about their boundaries and expectations. Since there are cultural differences added to the mix in an interracial relationship, misunderstandings can easily occur. For example, body image and relationship norms might be perceived differently in different cultures, which can cause friction in the relationship.
