This is a very inappropriate situation. First, you should immediately stop reading such stories in her presence. Then, have a serious conversation with her about appropriate and inappropriate content. Make sure she understands that this kind of content is not suitable for her age.
Definitely not. Sharing something like that with a sister is highly unethical. Family relationships are based on respect, love, and appropriate boundaries. This kind of sharing violates those boundaries and can cause discomfort, harm to the relationship, and is not acceptable in a civilized family environment.
This is extremely inappropriate behavior. Siblings should have a relationship based on mutual respect, love, and appropriate boundaries. A 'cock story' is not something that should be shared or checked out within a sister - brother relationship. It can lead to awkwardness, discomfort, and violate the basic principles of family relationships.
Such a question is highly improper and not within the realm of decent conversation. It is important to maintain respectful and appropriate language in all interactions.
It is far from normal. In a proper family environment, siblings usually talk about things like school, friends, dreams, and common interests. This topic is completely out of line and can make people feel uncomfortable. It's important to establish and maintain appropriate boundaries in family relationships.
I'm not actually familiar with a specific 'gimme back my hairy toe story'. It might be a very unique or local folktale. Maybe it's about a character who has lost his hairy toe and is demanding it back from someone or something. Without more context, it's hard to say exactly what the story is about.
Since I don't possess such a story of my own, but if we think about it in a general context, a girl might have her first experience with body hair awareness when she notices hair on her legs. She may initially be a bit confused or pressured by the social norms regarding body hair removal. Some may choose to embrace it, while others may start to explore different hair removal methods.
