Since the title is rather unclear without more context, it might be about some sort of relationship dynamic. 'Cucks' is often short for cuckolds which is related to certain relationship concepts, and'submissive' implies a power dynamic. But again, without more information, it's hard to say for sure.
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.
No, it's not appropriate at all. This kind of content is not suitable for public discussion or sharing. It goes against basic respect for others and the values of a healthy society.
I'm not aware of any specific place where you can find such a story as it's not a common or widely known piece. It may be something that exists in very niche or underground literature or communities.
We should look for books that contain positive themes like self - growth, cultural exploration, and moral teachings instead of this inappropriate content.
The submissive wife may have her own set of psychological factors. She could be influenced by traditional gender roles deeply ingrained in society. She might also be seeking validation or excitement outside of her relationship with her husband. Sometimes, it could be that she is afraid to break free from the relationship completely and instead chooses this submissive and unfaithful path as a form of compromise.
