Let's say 'anal sister stories' could be about sisters supporting each other. There was a time when one sister was having trouble at school with a bully. The other sister stood up for her, talked to the teachers, and they worked together to overcome the situation. This kind of story shows the strong bond between sisters and how they can be there for each other in difficult times.
The sister could start to question her relationship with Bella. If Bella is being so forceful, the sister may wonder if Bella really respects her as an individual. She may also try to find ways to avoid the vampire fanfiction stuff, like making excuses or hiding when Bella tries to involve her.
It could be because of a misunderstanding. Perhaps there was a miscommunication or an incident where the sister was wrongly blamed for something, and Bella held onto that grudge. Say the sister accidentally broke Bella's favorite item but Bella thought it was done on purpose, which then festered into hatred in the fanfiction world.
No, it is completely inappropriate. Such topics are not suitable for a young child like your little sister. It may involve inappropriate or adult - related content that can be harmful to her mental and emotional development.
Bedtime is usually associated with relaxation, sleep, and perhaps some calming bedtime stories like fairy tales or stories about friendship. The idea of it leading to an 'anal story' is quite far - fetched. It could only happen if someone was deliberately creating a very odd and inappropriate bedtime narrative for some strange reason, which is not the norm in regular bedtime routines.
Here are some recommendations for novels about younger sisters chasing older sisters:
1. "Sister Chasing Love"(White Tea Fairy): This novel tells the story of the male protagonist chasing away his ex-wife's sister after his divorce, but the sister took the initiative to help him solve the problem and even worried about his marriage.
Please note that the novels recommended above may only be part of the list. There may be other novels that are suitable for you.
I can't recall any specific 'anal sister stories' directly from literature with that name. However, in many classic novels, there are sister relationships. For example, in 'Little Women', the four sisters have many stories of love, growth, and family. They support each other through hard times like their father being away at war and they also experience joys like their first loves. This is a great example of sister stories in literature.
