In some 'Naruto and Alien Lemon' fanfiction, the plot could start with a strange phenomenon in the Naruto universe that is actually caused by an alien experiment gone wrong. The 'Lemon' aspect could be a chemical or substance that the aliens were working with. Naruto and his team are tasked with investigating this. As they get closer to the truth, they find out that the aliens have different motives, some good and some bad. There could be battles, negotiations, and character development as Naruto and the aliens interact. And in the end, they might find a way to either use the 'Lemon' related thing for good or get rid of it to restore peace in the universe.
A plotline could involve an alien being stranded in the Naruto world. Naruto, being the kind - hearted hero, decides to help the alien. Along the way, they discover that the alien has some knowledge or power that is related to the 'Lemon' concept, which could be a mysterious energy source. This energy source might have the potential to either save or destroy the Naruto world, and they have to figure out what to do with it. As they work together, they also learn about each other's cultures and grow as characters.
In a 'naruto is a alien fanfiction', a plotline could be that Naruto is the last of his alien kind, and there is a powerful enemy that is after the secrets locked within his DNA.

He also has to deal with the prejudice from some in the ninja world who fear his alien nature, all while trying to use his new - found powers for good and save the day.
Well, one possible plotline could be that Ayane, for some reason, enters Naruto's world. Maybe she's on a mission or has been transported there accidentally. And then, through a series of events, they start to develop feelings for each other that lead to the more 'lemon' - ish aspects of the story. However, this would require a lot of world - building to combine their two different universes.
Perhaps in a 'naruto and elf lemon fanfiction', the elf has a special power that the Naruto world needs to defeat a new and powerful enemy. Naruto and the elf team up, and during their adventures, they start to develop feelings for each other. Their relationship could progress from friendship to something more, with some tender and a few more suggestive scenes as they get closer, like a shared moment under a starry sky where their relationship takes a new turn.
Since 'lemon' often implies adult - themed content, I can't really provide detailed plotlines for that. But if we consider a general Naruto and Annabeth crossover without the 'lemon' aspect, a possible plotline could be them teaming up to face a common enemy that threatens both their worlds. Maybe they start off as rivals, not understanding each other's powers and ways, but gradually learn to work together.
In a naruto and fairy queen lemon fanfiction, perhaps the Fairy Queen is a powerful being from another dimension. Naruto accidentally stumbles into her world. The plot could involve Naruto learning about the fairy queen's magic and how it could be used to enhance his own abilities. Or it could be that there is a dark force threatening both the ninja world and the fairy queen's realm, and they must work together to defeat it. There could also be cultural clashes as Naruto's ninja values meet the more magical and ethereal values of the fairy queen's court.
One possible plotline could be that Naruto, in his travels, stumbles upon an elf realm. There, he meets an elf and they develop a romantic relationship with some 'lemon' elements like passionate encounters. Another could be that an elf is brought to the Naruto world and they have to navigate their cultural differences while falling in love in a more adult - themed way.
One possible plotline could be that Naruto somehow ends up in the Fate/stay night universe and meets Tohsaka Rin. They could team up to face a common enemy that threatens both their worlds.

One possible plotline could be that Lemon has some unique ninja abilities that Naruto discovers, and they train together to become stronger. Maybe she has a special chakra nature that Naruto has never seen before, and they figure out how to use it in combat.
Perhaps in a 'naruto x tifa lemon fanfiction', Tifa could be transported to the Naruto world. She might initially struggle to adapt to the ninja - based society. Naruto, being the friendly and helpful character he is, would assist her. As they spend time together, they start to understand each other's strengths and weaknesses, which could lead to a deeper connection. However, they also have to deal with the politics and power struggles in the Naruto world that might threaten their relationship.
A plotline might involve Ryuuzetsu and Naruto forming an unlikely alliance to fight against a common enemy. Maybe there's a new threat that neither the Leaf Village nor the Hidden Mist Village can handle alone. They would have to combine their skills and learn to trust each other. Ryuuzetsu could teach Naruto some of the Hidden Mist's combat strategies, and Naruto could share his never - give - up attitude with Ryuuzetsu.
