It is not appropriate at all. Watching sexual content together, especially with an ex - girlfriend, violates normal moral and ethical boundaries. Such behavior can be considered inappropriate and disrespectful to the concept of healthy relationships.
One consequence would be the destruction of the marriage. The husband would likely feel violated and may not be able to forgive such a transgression. Additionally, it could cause emotional trauma for the wife herself in the long run as she may come to regret her actions. It can also make her a target of unwanted attention from the stranger or others who hear about it, which could put her safety at risk.
One consequence could be the end of the friendship. The friend may feel extremely uncomfortable and violated, and may not want to have any further contact with the couple. Another consequence is that it can damage the couple's own relationship. They may later regret their actions and feel that they have crossed a line that they shouldn't have.
The story could revolve around how Junkook's best friend, the girl, helps him see things from a different perspective. For example, she might be really into environmental causes and gets him involved. They could go on trips together to do volunteer work. And their friendship is not just about having fun, but also about growing as individuals. They might have heart - to - heart conversations that help Junkook in his career decisions too.
One benefit is that it can expand his vocabulary. As he watches the story, he'll hear new words and phrases, which is great for his language development. Also, it can stimulate his imagination. The story's plot and characters can inspire him to create his own little worlds in his mind. Moreover, it might help him learn about different values and morals through the story's message.
I'm not entirely sure as 'erotic friend fiction' isn't a very common or mainstream term. It might refer to fictional stories that involve some form of erotic or sexual elements within the context of friendships. However, this is just speculation.
I'm not sure who 'she' is as the statement is rather unclear. It could be a character from a specific book or someone's personal account that we don't have enough context for.
It's not a good idea. Sexual stories usually involve adult - oriented and often inappropriate content. There are much better and more positive forms of entertainment like reading classic literature, watching educational documentaries or engaging in hobbies.
