Well, it could be a moment of intense emotion. Maybe Edward is angry or frustrated and his slamming into Bella is a moment of uncontrolled passion. It might lead to a big argument between them and then a subsequent making - up as they realize their feelings for each other are too strong to be torn apart by such a moment.
Perhaps in the fanfic, it's not a negative slamming. It could be a situation where Edward is trying to protect Bella from an immediate danger and in his haste, he slams into her. This could then set off a chain of events where they have to deal with the threat together and their relationship deepens as they rely on each other in the face of danger.
Finding a specific fanfic with that rather unique description can be a challenge. You could also try using advanced search options on fanfic platforms. For example, on Archive of Our Own, you can search for specific tags related to Twilight, Edward, and Bella, and then look for fics that might imply such an action in the summary or description. It may take some time and patience, but you should be able to find something if it exists.
One possible plot development could be that it's part of a game or a light - hearted situation. Maybe they are playing a role - playing game where this is part of the scenario. For example, they could be reenacting a scene from a movie or a story they both love.
One possible plot development could be that Bella's job as an exotic dancer draws the attention of the vampires in Twilight. Maybe they are intrigued by her confidence and allure in this new role, which could lead to new and different interactions compared to the original story.
There could also be an external threat that forces them to put aside their differences. For example, a new vampire or a group of enemies might attack their community. In this situation, Edward, Bella, and Jasper have to work together. During this time, Edward might realize that his jealousy is unfounded, and they all form a stronger bond as a result.
One possible plot development could be Bella trying to find a way to escape the forced marriage. Maybe she discovers some hidden secrets about Edward or the circumstances that led to the forced union, which gives her leverage to break free.
In some fanfictions, they could face new threats from other supernatural beings. Maybe a new coven arrives in town, and they have to protect their family and the town. This would put their relationship to the test as they deal with the danger together.
Another theme is the protection aspect. Edward is always protective of Bella, and fanfics play with this idea, creating new threats and situations where Edward has to protect Bella in more extreme ways.
Well, there are likely to be some 'Bella cheats with Edward' Twilight fanfics in the vast world of fanfiction. Fanfic writers like to play with different ideas and scenarios. But this particular scenario is quite a departure from the original story's portrayal of their relationship. It might be interesting to read for those who enjoy exploring different relationship dynamics in fan - created content, but it may also shock or disappoint traditional Twilight fans.
King Edward might become more protective and less focused on his kingly duties at first. As the story progresses, he could learn to balance his love for Bella and the baby with his responsibilities. Bella could become more confident in her role as a future mother and a queen - like figure in the kingdom.
One possible reason could be Edward's fear for Bella's safety. In the Twilight universe, Bella is constantly in danger because of her relationship with Edward. This overbearing worry might lead to arguments and ultimately a break - up. Another reason could be Bella's desire for a more normal life. Edward's vampire world is full of secrecy and danger, and she might feel exhausted from it.
