They could have been bored and just randomly chose to watch a stepmom story, and then got caught because it was an unexpected thing for them to be doing at that time.
'Caught watching stepmom story' simply means that an individual was found or detected while observing a story that involves a stepmother. The 'story' here could range from a simple short story, like those you might find in a magazine or online, to a more complex narrative in a movie or a long - running TV series. It's not clear from this phrase alone whether there is a positive or negative connotation to being 'caught'. Maybe the person was embarrassed to be caught because it was something private or perhaps they were just surprised to be discovered while engrossed in this particular type of story.
One reason could be that the story was too emotional. If it was a sad story, for example, the person might be so affected that they withdraw and seem blocked. They are just processing all those strong emotions.
Possibly the writing style didn't appeal to them or they didn't connect with the themes presented. Another reason might be that they expected something different based on the initial description and were disappointed.
If a brother is caught watching someone pee, he should be immediately reprimanded. The person who caught him should firmly explain that this is an unacceptable invasion of privacy. He should also be made to understand the harm he has caused or could cause to the person's dignity and mental state.
It depends on the nature of the stories. If they are positive and focus on healthy family relationships, then it can be appropriate. For instance, stories that show how a stepmom and stepchildren bond over shared interests or face challenges together in a respectful way.
Hard to say for sure. It could have been a comedy anime story to lighten her mood or a mystery one to keep her intrigued.
They could be saying it because they want to set boundaries. If someone is constantly talking about their love affair fanfic, it can be annoying. So this is a way to say 'stop involving us in it'.
To avoid misinterpretation. If the plot has some elements that could be misconstrued as ghost - related, they clarify it in advance.
That's a completely inappropriate and unacceptable topic. Such stories are immoral and violate common decency.
