One great fanfiction idea could be that Hestia Jones helps Sirius Black escape from Azkaban in a more covert way than in the original story. Maybe she uses some unique magic spells known only to her family line.
There is this amazing fanfiction that delves into what would happen if Hestia Jones was assigned to capture Sirius Black, but instead, she starts to believe in his innocence. It's a really interesting take on their dynamic, as she has to balance her duty as an Auror with her growing belief in Sirius. It has a lot of great character development and plot twists.
In fanfiction, their relationship could develop through a shared interest in magical history. Hestia Jones might be an expert in a certain area of magical history that Harry is also interested in. They could meet in a library or a museum, and as they discuss and research together, their relationship blossoms. Hestia could introduce Harry to old magical texts and secrets that he didn't know before, and Harry could share his own unique experiences with her. This exchange of knowledge and experiences could bring them closer together.
Perhaps Hestia Jones and Harry team up to rescue some captured magical creatures. They could face many obstacles along the way, and in the process, develop a strong bond of friendship.
Hestia Jones could be seen as a protector. If the lemon in the fanfiction represents something pure or valuable in the wizarding world, she would be the one guarding it. She would be brave and not afraid to stand up against those who would try to harm or steal the lemon - related thing. She might use her stealth and her knowledge of the wizarding world's hidden places to keep it safe.
One possible storyline could be that Hestia Jones plays a crucial role in protecting a lemon - themed magical object. Maybe it has some special powers related to healing or protection. And she has to face off against dark wizards who want to use it for evil.
I'm not aware of any particularly popular 'Harry Potter and Hestia Jones' lemon fanfictions. Since this is a rather niche area and lemon fanfictions are not always widely promoted due to their mature nature.
One good 'Harry Potter Hestia Jones' fanfiction could be 'Hestia Jones: The Unsung Heroine'. It might explore her role in the wizarding world in more depth, perhaps her interactions with other Order of the Phoenix members. Another could be 'Hestia Jones and the Lost Artifacts' where she goes on a quest to retrieve important magical items. There are also fanfictions that focus on her backstory, like how she came to be involved with the Order.
First, do a lot of research on the Harry Potter universe, especially about the time period Hestia Jones is in. Read the original books carefully to understand the rules, the culture, and the characters. Then, think about what kind of story you want to tell with Hestia. Is it a story about her heroism? Or her personal growth? Start with an outline, including the beginning, middle, and end. For example, you could start with Hestia getting a mysterious mission.
