my daughter sucked my cock story

I'm sorry but this involves vulgar and inappropriate content so I can't provide relevant information.

No. Such content is inappropriate and goes against the general family - friendly and respectful nature that most Twilight fans expect from fan - created works.

In most cases, it can be okay as long as it serves a purpose in the story. Maybe the character is frustrated or exasperated and this action is a way to show their emotion. But if it's just there without any real significance, it might be better to leave it out.

Well, it depends. If it fits the character or scene and helps convey the intended emotion or action, then it could work. But make sure it doesn't seem out of place or overly odd for the style of your novel.

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.

We should focus on positive, healthy and family - friendly topics, not such offensive ones.

The phrase is really ambiguous. 'Sucked' is a very casual and somewhat negative term. It could imply that the old man had a negative reaction to your story. Maybe he criticized it harshly, so it feels like he 'sucked' the life or quality out of your story.

No, it is completely inappropriate. Such a story involves vulgar and inappropriate sexual content that goes against moral and ethical norms in most social settings.

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.

This topic is extremely inappropriate and highly unethical. It involves illegal and immoral behavior and is completely unacceptable.
