I haven't come across a 'girlpenis bella twilight fanfic' myself. Fanfic communities cover a wide range of themes and interpretations, but this one might be quite unique. It could also be that it doesn't exist at all, or if it does, it might be in a very niche part of the Twilight fanfic world. Try looking on popular fanfic websites and use specific search terms to see if you can find anything related.
Yes, there are likely various fanfictions with this concept. Twilight has a large fan base, and many fans like to explore different takes on the characters. Some might imagine Bella as a white wolf for unique storylines, character development, or to add a new twist to the existing Twilight universe.
In these fanfictions, Bella as an Alpha is often more confident. For example, she may not shy away from making tough decisions like she sometimes did in the original series. She is usually physically stronger and has enhanced senses. This allows her to better protect those she cares about, whether it's her family or friends in Forks.
In many Twilight fanfictions, Edward and Bella's kiss is often depicted as an extremely passionate and intense moment. Some fanfictions might explore different scenarios around this kiss. For example, it could be set in an alternate universe where they meet under different circumstances before the kiss. The kiss in fanfiction can also be used to show a deeper connection between them than what was shown in the original books. It allows the writers to play with the emotions and the relationship dynamics in a more creative way.
Twilight is a popular series and there are a vast number of fanfics out there. However, writing or promoting fanfics that involve non - consensual or inappropriate sexual content like this goes against the spirit of the original work and many ethical standards. So, while there may be some out there in the darker corners of the internet, it's not something that should be actively sought or encouraged.
No, it's not appropriate. Abuse in any form, whether in real life or in fictional stories, is a very serious and disturbing topic. And when it's combined with a disabled character like Bella from Twilight, it can be even more offensive. The Twilight series is mainly about love and supernatural elements, not about such dark and inappropriate themes.
There might be some very inappropriate and non - canonical fan - created works out there that might have such disturbing content, but it's not something that should be promoted. The Twilight saga is known for its vampire - human love story, not this kind of improper relationship.
One interesting Bella Twilight fanfic could be one that explores Bella's life if she had different vampire powers. For example, instead of the typical vampire abilities in the original story, she might have the power to control the elements, which would completely change the dynamic of her relationships with Edward and the other vampires. Another could be a fanfic that focuses on Bella's friendship with Jacob from a different angle, like if they had met under different circumstances before the events of the main story.
