It depends on the type of stories. In some melodramatic or soap - opera - like stories, this might be a more common trope to create drama and conflict. But in general, in real - life - inspired or positive - themed stories, it's not so typical. It goes against the values of friendship and marriage.
Well, in a fictional story, a friend might have had a drunken night with his best friend's wife at a party. They both made a huge mistake that night, and later found out she was pregnant. This situation would then lead to a lot of drama, including the breakdown of the friendship and the potential end of the marriage.
One possible story could be about a group of friends where one couple has a femdom relationship. The wife in that relationship might be in charge of certain decisions, like planning the group outings. For example, she decides on the destination and activities for a weekend getaway with the friends. This shows her dominance not only in her marriage but also in the social circle to an extent.
Perhaps in a story where the 'wife sold to friends' is a misnomer. For example, the wife might be a part of a group of people who trade skills or knowledge. She offers her expertise in cooking or gardening to her husband's friends in exchange for their skills in carpentry or music lessons. This kind of exchange could be misinterpreted as being sold, but in fact, it's a positive and equal - opportunity interaction that enriches everyone's lives.
One surprising story could be about a husband who planned a big surprise party for his wife with the help of their friends. They decorated the house, invited all their close ones, and when the wife came home, she was overjoyed. It was a great celebration of their relationship and the support of their friends.
It is completely unethical. A friend's wife has her own dignity and privacy. Her relationship with your friend is based on trust and mutual respect. By sharing stories about her, you are not only disrespecting her but also your friend. This kind of behavior can create a rift in the friendship and damage relationships within a social circle.
Another positive story could be that the wife has just completed a fitness journey and is now in great shape. She shares with her friends how she achieved this, like her exercise routine and healthy eating habits. It can be an inspiration for her friends to also pursue a healthier lifestyle. In this case, she is 'flashing' her positive achievements to her friends in a good way.
One story could be that a wife organized a surprise party for her husband with the help of their friends. They all secretly decorated the house and prepared his favorite food. When he came home, he was overjoyed at the sight of all his friends and his loving wife waiting for him.
