Yes, there might be. Fanfiction websites often have a wide variety of stories based on different themes and character pairings. You could try searching on popular fanfiction platforms like Archive of Our Own or FanFiction.net to see if there is a 'Sally Seduces Percy' fanfiction.
Perhaps Sally has some ulterior motive for seducing Percy. Maybe she's trying to get information from him or is part of a plot against him that she later has a change of heart about. She could use her charm and beauty to draw him in. She might start by dressing in a way that catches his attention and then use her wits to keep him interested. Along the way, Percy could be initially oblivious to her intentions but then start to fall for her as well, leading to a complex relationship dynamic.
Sally and Percy are likely characters within the context of a particular fanfiction universe. They could be original characters created by the fanfiction writer, or they might be based on existing characters from a book, movie, or TV show.
No. Fanfiction that involves sexual content between family members, like Percy and Sally who have a mother - son relationship in the original context, is highly inappropriate and goes against moral and ethical norms.
Writing fanfiction about such a disturbing and inappropriate topic as rape is unacceptable and violates basic moral and ethical standards. So, it should not exist and I would not support or promote any such content.
Another reaction could be that Percy is worried about Sally getting into trouble because of him. He might try to convince her to stay out of it, fearing that the abuser or those associated with the abuser could harm Sally. But at the same time, deep down, he wants her support and protection.
Sally would likely become a mother figure to Annabeth. She would offer her advice and support, just as she does for Percy. Percy and Annabeth's relationship would become more domestic. They'd have more time to just be together, sharing small moments like having breakfast together in the morning. Their bond would strengthen as they face the normal day - to - day challenges of living together, along with Sally.
One common theme is family. Since Sally is Percy's mother, a lot of fanfictions explore their family bond, like how Sally protects and guides Percy. Another theme is sacrifice. Sally often sacrifices for Percy in these stories. For example, she might put herself in danger to save him. Love is also a big theme. It can be Sally's motherly love or Percy's love and respect for his mother.
A fanfiction might revolve around a day in the life of Percy and Sally. The lemon could be part of a recipe that Sally is making when suddenly something from the demigod world interrupts. For example, a monster is drawn to the smell of the lemon dessert she's preparing, but Percy is there to save the day. It could show the normalcy of their life mixed with the chaos of the demigod world.
Fanfiction often takes existing characters and creates new, sometimes dark, storylines. In the case of 'percy abused by sally fanfiction', it could be a way for the author to explore complex and often disturbing themes. Maybe the author wants to show how Percy copes with this difficult situation, or perhaps it's a statement about power dynamics. But again, this is all speculation without actually reading the fanfic.
