Well, without actually seeing such a fanfiction, it's hard to say. But perhaps it could be about a character named Percy who has some sort of power related to sex in a very fantastical and made - up world, and the lemon aspect could imply some sort of citrus - related or tangy element in the story, though that's a very strange combination.
I'm not sure if there is a specific 'Percy God of Sex Lemon' fanfiction. Fanfiction can cover a wide variety of themes and characters, but this seems like a rather unusual and perhaps not very common combination. It might be difficult to find such a specific one.
Well, if it was non - adult - themed, perhaps Percy becomes the 'god of sex' in a very metaphorical sense. Maybe it could be about him being in charge of relationships and the deeper emotional and physical connections between people in a very chaste way. For example, he could be the one to bring about understanding and harmony in relationships that are often associated with sexual attraction but in a completely non - sexual context.
In a Percy Jackson God of Fire fanfiction, he could be a very different kind of God of Fire compared to the traditional ones. Since Percy has his own unique personality, he'd bring a sense of humor and a bit of a rebellious streak to the role. He might not follow all the old rules of being a god. For example, instead of just staying in Olympus, he could be down on Earth more often, helping out demigods directly. He could also use his fire powers in creative ways during battles, like making the ground erupt in flames in specific patterns to trap enemies.
Another plotline might be that Percy betrays God out of a sense of self - preservation. Suppose there's a great threat coming, and Percy believes that siding with an enemy of God is the only way to save himself or the world he cares about. He might think that God's power is not enough to protect them, and so he makes a deal with the other side, which is seen as a betrayal.
Perhaps it's a time - travel fanfiction. The lemon is an important item in a different era that Percy and Sally have to retrieve. They have to navigate through different mythologies and challenges to get it, and along the way, they learn more about each other and their own powers.
I'm not sure which specific 'Percy God of Sex' fanfic you're referring to. There could be many interpretations of a character named Percy in different fan - created stories. It might be an original character created by the fanfic writer with their own unique backstory and characteristics within the context of that particular fanfic.
In a 'Percy as god of time' fanfiction, perhaps Percy discovers his role as the god of time after some sort of strange encounter with an ancient artifact. He then has to learn how to control his powers. He could start by accidentally messing up the timelines, like making people age too quickly or events happen out of order. As he learns, he might use his power to give his friends extra time during battles, slowing down the enemies while his friends can attack more freely.
Friendship and camaraderie is also a likely theme. Percy's loyalty is often tied to his relationships. Fanfictions could show how his loyalty to his friends shapes the group dynamic and how they, in turn, show loyalty to him, creating a cycle of mutual support and trust.
One possible plot could be Percy facing an ultimate battle that forces the Olympians to recognize his extraordinary powers. They then decide to make him a god as a reward and for the greater good of the pantheon. He might have to give up some of his mortal ties, like his relationship with Annabeth, which would create a great internal conflict for him.
In Percy Jackson fanfiction, the idea of a 'God of Sex Harem' is a rather strange and often inappropriate deviation from the original themes. The Percy Jackson series is mainly about Greek mythology, friendship, and heroism. Fanfictions should focus more on positive aspects like exploring new adventures for Percy and his friends within the framework of the mythology rather than creating such improper concepts.
