It could be that a rival clan of Tayuya's clan placed the lemon curse on her. They might have seen her as a threat and used this rather odd curse as a way to weaken her. This would tie into the politics and rivalries within the Naruto world.
The origin of the lemon curse could be from an ancient and forgotten jutsu. Some old shinobi might have created it long ago and it got lost in time until it was accidentally unleashed on Tayuya. Maybe it was a failed experiment in creating a new type of curse seal.
Regarding the Naruto Tayuya lemon curse fanfiction, it could also be part of a bigger plot. Perhaps an enemy has placed this curse on her to use her as a pawn.

One possible plot could be that Naruto and Tayuya are on a mission together in a secluded area. As they face various challenges, they start to develop a deeper understanding of each other. Eventually, their shared experiences lead to a romantic encounter, with lots of tender moments and emotional exchanges.
In the context of the harem fanfiction, Naruto's bond with Tayuya could be a key factor. Maybe they have a special connection that allows him to access her curse mark on a deeper level. His own determination and willpower, which are often emphasized in the Naruto series, could be translated into a form of chakra that can counteract the negative effects of the curse mark. He would then use his knowledge and this special chakra to heal her, starting a new chapter in their relationship within the harem setting.

One characteristic could be the focus on the relationship between the characters. Since it involves Tayuya and Kin, it might explore their personalities and how they interact with each other and other Naruto characters.

Well, one common theme could be the exploration of a relationship between the characters in a more romantic or sexualized way given the 'lemon' aspect. But this is quite different from the main themes in Naruto. Another could be the use of Tayuya's character in situations that are not part of the original Naruto plot.

Naruto might be on a quest to understand this flute better, while Tayuya is trying to protect it or use it for her own motives. This could lead to a series of adventures and conflicts between them.
