Yes, there are many normal 'Harry Potter' fanfics that involve his aunt in a non - inappropriate way. For example, some might explore her relationship with the Dursley family dynamic in a more family - oriented or comical context.
Another idea is a time - travel fanfic where Aunt Petunia goes back in time and meets a young Lily. This could explore their sisterly bond and how it might have changed over time. It would focus on family relationships and the magic world in a clean and interesting way.
A popular one might be 'Aunt Petunia's Redemption'. In this fanfic, Aunt Petunia goes through a journey of self - discovery. She starts to question her hatred towards Harry and the wizarding world. As she delves deeper, she finds out some secrets about her family's connection to magic that she never knew before, which ultimately leads to her trying to make things right with Harry.
In the fanfiction, they could be forced to work together on a project related to lemons. Maybe there's a local fair that requires everyone to contribute something lemon - themed. Through this shared task, they begin to understand each other better. Harry realizes that Aunt Marge has her own insecurities and Aunt Marge sees that Harry is not the troublemaker she thought he was. For instance, Harry could show his creativity and intelligence during the project, impressing Aunt Marge.
There really shouldn't be. Harry Potter is a story aimed at a wide range of audiences, including children. The 'perverted daddy' concept is not only against the spirit of the original work but also can be considered offensive. Fanfiction is supposed to be a creative expansion of the original story in a positive way, not something that involves abnormal and inappropriate content.
I'm not sure which novel you're referring to because you didn't provide any relevant information. If you can provide more context or details, I will try my best to provide you with a more accurate answer.
Aunt Lemon might also impact Harry's life by introducing him to a different side of the Muggle world. Maybe she has a love for art or music, and through her, Harry discovers these aspects of Muggle culture that he otherwise would have been deprived of. This newfound interest could help him better understand the differences between Muggles and wizards and appreciate both worlds.
One possible fanfiction could be about Aunt Petunia having a strange encounter with a lemon - themed magical object. Maybe she accidentally uses it in a spell (in a non - canon, fan - created way) that makes her see a different side of the wizarding world she has always despised. This could lead to her having a change of heart about Harry Potter and his world.
She is very much concerned with appearances and normalcy. In the Dursley household, everything has to be in a certain order and conform to what she deems as a proper, non - magical lifestyle. This is part of the reason she is so resentful of Harry and his magical abilities.
There could be a 'Aunt Marge likes Harry fanfic'. Fanfic communities are full of diverse interpretations of characters and relationships. It might explore a different side of Aunt Marge's character, perhaps in an alternate universe where she doesn't hold her usual grudges against Harry. You could also try reaching out to Harry Potter fanfic communities on social media platforms to ask if anyone has read or written such a fanfic.
