Yes, there are some. You can start by looking on popular fanfiction websites like Archive of Our Own or FanFiction.net. Just search for the specific tag 'Edward is Bella's step dad' and you'll find various stories with different takes on this rather unique concept.
One possible plotline could be Bella initially resenting Edward as her step - dad but then gradually coming to understand him better and they form a unique bond. Another could be Edward struggling with his new role and having to deal with his own feelings for Bella in a more platonic way than in the original story.
Yes, there are some out there. One interesting one might be 'Forbidden Ties' which delves into the complex emotions that come with their new family relationship. It explores how they struggle to deal with their growing feelings for each other in a situation that society deems unacceptable.
In general, it can be appropriate as long as it doesn't cross any lines. Fanfiction often takes existing characters and puts them in new situations. If the 'Edward and Bella step siblings fanfiction' is about their new family dynamic, like how they deal with being step - siblings, it's okay. But if it has any inappropriate undertones related to their new relationship, then it's not suitable.
One common theme is the struggle against society's norms. Since they are step - siblings, their relationship is considered taboo, so they often have to fight against what society expects of them.
In the 'bella is edward's pet fanfiction', the relationship is a creative and often controversial take. It could be that the author is exploring themes of dependency and power. Bella as a pet might symbolize her vulnerability and Edward's strength. However, this also raises questions about her agency. Does she have any say in things? Or is she completely at Edward's mercy? It can be a very complex relationship to unpack within the framework of the fanfiction.
Well, a plot could revolve around Edward and Bella's step - parent relationship. Maybe their new parent has some secrets that are affecting the family. Edward and Bella team up to figure out what's going on. Also, they could be competing for their parents' attention at first, but then realize that they can support each other instead. And there could be a sub - plot where they both get involved in a community project together and through that, their step - sibling bond becomes even stronger.
Gildarts could be a great choice. He's a powerful and well - known wizard in Fairy Tail. His laid - back yet strong personality would make for an interesting step - dad. He could teach the younger members a lot about magic and also about life in general.
It redefines it by making it unequal. Bella is in a position of being 'owned' in a sense, which is a huge change from their normal relationship where they are more like equals in love.
Another possible location could be an old, abandoned church that has been restored just for their wedding. The stained - glass windows and high ceilings would create a very solemn and beautiful atmosphere. It could also have some kind of connection to Edward's past, like it was a place his family once visited long ago.
