The term 'bulma hentai fanfic' is a disturbing concept. Hentai is a genre that often includes sexual and inappropriate content. Using a character like Bulma from an anime in such a context is wrong on multiple levels. Firstly, it objectifies the character. Secondly, it creates a negative and unethical environment in the fan community. Anime is meant to be a form of art and entertainment that can be enjoyed by a wide range of audiences, and this kind of inappropriate fanfic goes against that spirit.
It cannot be considered legitimate. Fanfiction is a way for fans to express their love for a work in a creative way. However, 'bulma hentai fanfic' with its hentai nature is inappropriate. It not only violates the moral code but also disrespects the original creation. A legitimate fanfic would build on the existing world and characters in a positive, non - vulgar way, which 'bulma hentai fanfic' clearly fails to do.
Hentai comics often present an exaggerated and fictionalized version of baby-making that doesn't reflect reality. It's mostly for adult entertainment and not based on actual biology.
The safety of your hentai comics is hard to say for sure. It could be at risk if they violate any laws or if you don't take proper precautions to protect your privacy and the content. Make sure you're within the legal boundaries and safeguard them appropriately.
