No, it is not appropriate. Writing smut (pornographic or sexually explicit content) about any character, even an anthropomorphic one like Fluttershy, goes against ethical and moral standards. It also violates the rules of most fan communities and can make others uncomfortable.
You could write positive and friendly adventures for Fluttershy. For example, stories about her helping other animals in the forest or making new friends in Ponyville.
Anthropomorphic fanfic is a type of fan - created fiction where non - human characters, like animals or objects, are given human - like characteristics. For example, in some anthropomorphic fanfics, animals can talk, walk upright, and have complex emotions and social structures similar to humans. It often draws from existing fictional universes, such as cartoons or video games, and expands on the stories or characters in unique ways.
In fanfic, 'anthropomorphic Celestia' means presenting the character Celestia in a human - like form. It gives her more relatable human characteristics and behaviors, which can be used to explore different storylines and relationships within the fan - created narrative.
Fluttershy and dragon fanfic often explores unique relationships. In many such fanfics, Fluttershy's gentle nature contrasts with the powerful and often mysterious nature of dragons. It can show how Fluttershy's kindness might tame a dragon or how they form an unlikely friendship. For example, Fluttershy could use her understanding of animals to communicate with a dragon in a way others couldn't.
