Finding 'Harry Potter x Petunia Dursley' lemon fanfiction might be a bit tricky. First of all, the relationship between them in the original series is quite antagonistic. And secondly, 'lemon' content often goes against the terms of many platforms. But if you really want to look for it, you could join some Harry Potter fanfiction communities and ask around, though you may be met with some disapproval due to the nature of the content. Fanfiction should ideally be about exploring different aspects of the characters in a more positive and non - inappropriate way.
I don't recommend seeking out 'lemon' fanfiction in general, especially for a pairing like Harry Potter and Petunia Dursley. Their relationship in the books is complex and not really the kind that lends itself well to such adult - themed interpretations. Instead, there are many great non - 'lemon' fanfictions that explore their relationship in more interesting and appropriate ways, like how Petunia's feelings towards Harry might have changed over time without any inappropriate undertones.
I'm not sure if there are 'popular' ones in the sense that they are widely known and accepted. Lemon fanfictions are a bit of a niche and often not mainstream due to their mature content. But there might be some that have a following within the more hardcore Harry Potter fanfiction community.
One popular 'Harry Potter x Petunia Dursley fanfiction' is 'A Different Perspective'. It delves into the complex relationship between them in a really interesting way. It shows how Petunia might have had some hidden feelings towards Harry all along, which was not explored much in the original books.
By focusing on their shared past traumas. For example, both have had experiences related to Lily's death in different ways. Harry lost his mother, and Petunia lost her sister. They could start to bond over this common pain and gradually move towards a more positive relationship.
Fanfiction can cover a wide range of themes, but 'Harry Potter x Petunia' with a 'lemon' aspect is not something that aligns well with the overall tone of the original story. The series is mainly about magic, friendship, and the fight against evil. If you're interested in their relationship, look for fanfictions that explore their family dynamic, like how Petunia's jealousy and fear influenced her treatment of Harry, rather than 'lemon' ones.
One common theme is redemption. Fanfictions often explore Petunia's chance to redeem herself in Harry's eyes after years of treating him poorly. For example, she might suddenly realize the importance of family and try to make amends.
Yes, there are quite a few. You can start by looking on popular fanfic websites like Archive of Our Own. Some fanfics might explore a more complex relationship between Harry Potter and Petunia that wasn't fully shown in the original books. They could delve into Petunia's hidden feelings towards Harry, or how their relationship could have developed differently under certain circumstances.
There could be a fanfiction where Petunia Dursley discovers some hidden magic within herself and this somehow links her more closely to Harry. In this scenario, the story could take on a whole new dimension. But as for a particular 'Harry Potter and Petunia Dursley lemon fanfiction', it's hard to point out one without really searching through various fanfiction sites. Also, remember that lemon content often implies sexual undertones which may not be appropriate for everyone.
In a more comical plot, the lemon could be a mischievous magical object that keeps causing chaos in Petunia's house. It might make things float or turn into strange creatures. Petunia, being the uptight person she is, has to deal with this lemon - induced mayhem while also trying to keep up appearances in front of the neighbors. This could lead to some really funny situations and a change in her attitude towards the strange and magical over time.
I'm not sure specifically about 'Harry Potter Petunia Slave' fanfiction. There are so many fanfictions in the Harry Potter universe that it can be hard to find ones with such a specific and rather unusual concept. You could try searching on major fanfiction platforms like Fanfiction.net or Archive of Our Own and use those exact keywords to see if anything comes up.
Maybe she secretly has a soft spot for the magical world she once shunned. Fanfiction might offer her a different perspective on Harry's life, one that she can explore without fully admitting her growing curiosity or even a latent affection for the boy she once treated so poorly.
