Definitely not. Such a topic is not only inappropriate but also can be offensive to many. We should focus on positive, respectful and inclusive forms of art and literature rather than this kind of thing that objectifies or makes inappropriate references.
I'm not entirely sure what specific 'Small Penis Fan Fiction' is. It could potentially be a form of fictional writing within certain niche or inappropriate communities. However, this is not a mainstream or positive form of literature in general.
There could be many interpretations of a 'wife small penis story'. It might be a fictional tale someone created about a relationship situation where the wife has an encounter or experience related to this rather inappropriate and private topic.

In a way, they are. These kinds of stories usually focus on a particular aspect of a person's body in a negative light. Body shaming through such stories can have a serious impact on a person's self - esteem and mental health. People should be more aware of the harm these stories can cause and refrain from spreading them.
This kind of description goes against the spirit of Naruto which is about friendship, growth, and heroism. A proper Naruto fanfic could be about Naruto's journey to become a better Hokage, his relationships with Sasuke and Sakura evolving, or his training with new jutsu.

It could also be a satirical story where a mom accidentally discovers some comical misunderstandings related to the concept in a family or social setting. For example, a child misinterprets a conversation about small things and relates it to the male anatomy, and the mom has to clarify in a really funny way.
No. It is not acceptable. Fanfiction should uphold certain standards of respect and propriety. Naruto is a story loved by many for its themes of courage and camaraderie, and such inappropriate topics have no place in the fan community.
