Yes, some classic novels might allude to such relationships in a very veiled way. For example, in certain works where the relationship between a husband and wife is explored deeply, there could be implications of such intimacies. But it's not often explicitly stated as 'blowjob from wife stories' because of the propriety of the literary world.
Definitely not. These are personal and private matters between a couple. Publicly sharing these kinds of stories is disrespectful to the relationship and the individuals involved. It goes against the norms of decency.
Rather than seeking out such stories which are in bad taste, we could concentrate on stories about building strong, faithful relationships. There's no value in promoting stories that involve infidelity in such a salacious way.
No, it is not appropriate in most social and moral contexts. Such a story involves vulgar and inappropriate content that goes against the norms of respectful communication within a relationship and in society at large.
One common theme is loyalty. The wives often stay loyal to their husbands despite the crime they committed. Another theme is sacrifice. They may sacrifice their own social lives and financial stability to support their imprisoned husbands.
We should avoid them because they are disrespectful to others. Cheating is a very private and often painful matter for those involved, and making it into a 'story' for entertainment is wrong.
No, it is not appropriate at all. Spreading such stories about someone's wife is a serious invasion of privacy and is unethical. We should respect others' privacy and dignity and not engage in spreading unseemly rumors or stories.
