my sister'sman wants my giant cock sex stories

This kind of statement involves vulgar and inappropriate sexual content, which is not acceptable in civilized society. We should focus on positive, respectful and ethical topics.

This is a very concerning situation. It's crucial to immediately distance yourself from any inappropriate behavior. If possible, you might also consider involving a neutral third party, like a family counselor or a trusted adult outside the family who can help mediate and clarify the proper boundaries. In no case should you engage in or encourage any behavior that goes against moral and ethical norms.

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.

Tell her directly that these stories are inappropriate and you won't share them.

Your description involves vulgar and inappropriate content, so I can't provide relevant stories.

Well, this is a very uncomfortable situation. You might want to have a serious conversation with your sister about appropriate boundaries in a family. Explain to her that such a request crosses a line and it's better to focus on more positive, non - inappropriate things. For example, you can encourage her to share her own interesting experiences at school or work instead. Family members should respect each other's privacy and propriety at all times.

Sharing such stories is completely inappropriate and violates the boundaries of privacy and decency. Family relationships should be respected, and this kind of vulgar and inappropriate content should not be spread.

This kind of situation is not acceptable in a normal family relationship. You need to make it clear that there are boundaries in communication. You might say something like 'Sis, that's not something we should be talking about. Let's focus on other things like our family plans for the holidays or how we can help each other with our studies or work.'

I can't provide stories related to this as it is not suitable for general discussion.

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.
