little sister wants to suck my cock story

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.

Such a topic is morally and socially unacceptable. We should focus on positive and healthy subjects rather than engaging in such inappropriate discussions.

No. It is extremely vulgar and inappropriate language that violates basic social etiquette and respect for others.

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

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.'

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.

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.

Teaching such behavior is unethical and can have negative consequences. It's important to provide age-appropriate and beneficial guidance to siblings instead.

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

Perhaps 'suck' here is used in a more figurative sense, indicating that she really wants to soak up or absorb stories. It might be a good idea to encourage her interest. You could take her to the library regularly so she can explore a wide variety of stories on her own. And also, you can ask her what kinds of stories she likes, for example, does she prefer stories about animals or heroes? Then you can look for relevant books or even create your own stories for her based on her interests.
