You can also write about their training. Maybe they are training together to improve their combat skills or their magical abilities. This way, you can still explore their characters in a positive and appropriate way.
No, it's not appropriate. Writing such sexually explicit fanfic involving underage characters (if they are in the original context where they are underage) is unethical and goes against moral and often community guidelines.
No. Writing fanfic that involves sexual content about fictional characters is inappropriate and violates the respect for the original work and its intended audience. It also goes against ethical and moral standards in most communities.
There are many alternatives. One could write fanfiction about their adventures together, exploring new lands or fighting new enemies. Another option is to focus on their friendship, how they support each other through difficult times. You could also write about their character development, for example, how Piper becomes a stronger character or how Percy learns new skills.
There should be non - adult versions or interpretations of fanfics. Fanfic writers can create stories that focus on the friendship between Percy Jackson and Piper, perhaps in a bathroom or shower - related scenario that is completely platonic. For example, they could be having a conversation about a quest or some magical mystery while in a bathroom setting, without any inappropriate content.
You could also write AU (Alternate Universe) fanfic where they are in different settings like a modern - day high school but still maintain their non - sexual characteristics. They could be solving mysteries or participating in school competitions while still having the same core values and dynamics as in the original story.
You could write about their deep friendship. For example, how they support each other during difficult quests, share their secrets, and grow as individuals through their mutual trust. Another option is to focus on their rivalry in a friendly way, like competing to be the best at certain skills or tasks in their fictional world.
You could write action - packed fanfic. For example, create a story where Gwen Stacy teams up with other superheroes to fight a powerful villain. This would focus on her skills and bravery.
Another alternative would be to focus on their individual character growth. For Percy, you could write about his journey to master a new power or face a new challenge. And for Drew, perhaps her struggle to fit in with a new group while still staying true to herself. By focusing on these aspects, it creates more interesting and positive fanfic.
You could write about their friendship. For example, they could go on an adventure together, facing challenges and growing closer as friends. They might learn from each other's strengths and weaknesses.
Another alternative could be to explore their mentorship relationship. Maybe Hera gives Percy some advice on how to deal with the complex politics among the gods, which would be an interesting and appropriate story angle.
