Fanfictions often take characters and put them in situations that deviate from the original source material. In this case, with Hermione and Fleur in a forced bondage situation in a fanfic, it could potentially be a way for the author to explore themes of power, vulnerability, and trust. But it's important to note that the 'forced' part is a very tricky and often uncomfortable area, especially when it comes to real - world values and how we view relationships between characters.
It's likely that it would change the perception of their characters significantly. Hermione, who is known for her strong - willed and intelligent nature, would be in a very submissive and difficult situation. This could potentially show a different side of her vulnerability. For Fleur, it might also shatter her usually confident and somewhat haughty image, making her seem more fragile.
One possible plot could be that Hermione, as a Lycan, struggles to hide her identity within the Hogwarts community. Fleur, being perceptive, might notice something off about Hermione. Maybe Hermione is afraid of being discovered and ostracized, while Fleur, having her own experiences with being different (as a Veela), tries to help Hermione come to terms with her new lycanthropy. They could form a strong bond as they both deal with the challenges of being 'other' in the wizarding world.
Well, it could develop into a story of deep friendship. Maybe Fleur was trying to comfort Hermione during a difficult time. They might start sharing their secrets and fears, and through this physical closeness, a strong bond of sisterhood could form.
One possible plot could be a story set during a Triwizard Tournament - related event. Maybe Fleur and Hermione are forced to work together in a dangerous task and during a moment of panic or urgency, Fleur straddles Hermione to protect her from some sort of threat. And from there, a new bond forms between them.
Well, it could start with Hermione realizing her deep feelings for Fleur. Maybe she plans a very elaborate and romantic proposal. She might choose a special place like the Hogwarts grounds under a full moon. Fleur could be initially shocked but then really touched by Hermione's boldness.
Another possibility is that Fleur, in a bid to gain more influence in the magical world, uses Hermione's research on some ancient magic without permission. When Hermione finds out, she realizes Fleur has been using her all along, and this is the ultimate betrayal. Hermione then has to find a way to expose Fleur's actions and clear her own name.
Well, it could be a story about a deep emotional moment between Fleur and Hermione. Maybe they are in a situation where they are comforting each other or having a very intense conversation. It might also be part of a magical adventure where they are in a dangerous situation and this physical closeness is a result of trying to protect each other.
They might have a very competitive relationship. Since both are strong - willed and talented. They could compete in things like magical duels or academic achievements. However, this competition could also strengthen their bond as they push each other to be better. And in times of danger, they would put aside their differences and protect each other like true sisters.
Perhaps the plot could involve a love triangle. There could be another character, like Viktor Krum, who still has feelings for Hermione and is jealous of her relationship with Fleur. This would add drama and tension to the story. Also, Fleur's family might not approve of Hermione, leading to more conflict.
One possibility could be a situation where Fleur is under the influence of a dark spell. Maybe she's been hexed to do this to Hermione. In the fanfiction world, this could be a lead - up to a rescue mission by Harry and Ron. They would have to figure out how to break the spell on Fleur and free Hermione.
