A good James Potter and Lily Evans fanfiction with 'lemon' elements should first have well - developed characters. It should stay true to the original personalities of James and Lily from the Harry Potter series. For example, James was initially a bit of a prankster, and Lily was smart and independent. The 'lemon' part, if done well, should blend in with the story's overall plot and not seem forced. It should enhance the romantic or passionate relationship between the two characters. Also, the writing style should be engaging, with good grammar and pacing.
One popular Lily Evans Potter fanfiction is 'A Different Kind of Magic'. It delves into the relationship between Lily and James in a unique way, exploring their love and the magical world around them without going overboard on the lemon aspect. Another could be 'Lily's Hidden Journeys' which has some well - written romantic scenes involving Lily Evans Potter.
One common theme is their love story. How they overcame their initial differences, like James' early arrogance and Lily's initial dislike of him. Another theme is their role in the wizarding world. They were both important figures in the fight against Voldemort. Their friendship with other characters, such as Sirius Black and Remus Lupin, is also often explored.
I'm not sure about a specific fanfiction that combines all these elements exactly. But you could try looking on FanFiction.net. Search for stories with 'James Potter' and 'Lily Evans' in the title or description, and then look for ones that might be tagged with something related to the concept of 'lemon' (although this can be a bit tricky as different authors use different tags). You might have to sift through a few to find the perfect one that suits your taste.
A popular fanfic in this category is 'The Untold Story of Lily Evans Potter'. This story focuses on Lily's role in the fight against the Dark Arts during her time. It gives a detailed account of her relationship with James Potter from her perspective, which is really interesting as it often differs from what we can assume from the original books. It's a must - read for any Lily Evans Potter fan.
Tumblr can also be a source. There are often fanfiction recs on various Harry Potter - related Tumblr blogs. Look for tags like #LilyEvansPotter #fanfiction #lemon. But be aware that the organization of content on Tumblr can be a bit more chaotic compared to dedicated fanfiction platforms, so it might take some time to find exactly what you want.
One interesting plotline could be a story where Lily survives Voldemort's attack. In this scenario, she has to deal with the aftermath and also raise Harry in a very different wizarding world. Her relationship with Harry would be more of a traditional mother - son relationship, but with the added complexity of the wizarding world's politics and the threat of Voldemort still looming. This would allow for a lot of character development for both of them.
Since 'lemon' fanfiction is not suitable for promotion, I suggest looking for fanfictions that explore their love story in a more innocent and positive way. For example, some stories might focus on how they met at Hogwarts, their initial impressions of each other, and how their relationship grew over time. These types of stories can be really heartwarming and engaging without any inappropriate content.
One great fanfiction on this theme is 'The Marauders' Era: Lily's Perspective'. It delves deep into how Lily might have gradually fallen for James. It shows their interactions in Hogwarts in a very detailed and engaging way.
Typically, in a 'lily evans lemon fanfic', it might focus on the character Lily Evans in some romantic or relationship - centered scenarios. 'Lemon' often implies a more adult or sexual nature in fanfic terms, but if we're excluding that aspect, it could still be about her deep emotional relationships, her character growth, and her interactions with other characters in a more PG way.
