Maybe it's a self - discovery plot. Naruto has always felt a special connection to the Nine - Tails. One day, due to some internal spiritual awakening, Naruto starts to transform into a fox girl. This transformation makes Naruto re - evaluate his identity. He starts to explore the more feminine side of his personality and the hidden powers that come with the fox girl form. Along the way, he also helps other characters in Konoha understand that there's more to a person than their physical appearance, and his new form becomes a symbol of acceptance and change in the village.
In a 'naruto turns into a fox lemon fanfiction', it could be that Naruto is cursed by an enemy to turn into a fox, and the 'lemon' aspect could be symbolic.

Well, one interesting plot could be Naruto having to rely on his friends in a whole new way as a baby fox.

Maybe the main antagonist is an ancient spirit that has been awakened by Naruto's experiments with transformation. The spirit doesn't like Naruto's interference with nature's balance and decides to punish him by making him turn into a fox with the strange 'lemon' aspect.

Naruto would also have to deal with the cultural and social implications of being a fox girl in the ninja world, such as how he is treated differently by different clans.

Naruto's usually bold and outgoing personality might become more sly and cautious as a female fox.

Sakura might be really surprised at first. She could be a bit skeptical about whether it's really Naruto or some kind of trick. But then she would probably try to help him find a way to change back.
