It's completely inappropriate. Fanfiction should be a creative exploration of the existing story, characters, and themes in a positive and respectful way. 'Adventure Time' is a beloved franchise with a lot of positive values. Erotic fanfiction undermines those values and is not something that should be associated with it.
There are many positive alternatives. You could write or read general adventure - based fanfiction that focuses on the characters' adventures in Ooo, like Finn and Jake's quests to save the day. Another option is friendship - centered fanfiction, highlighting the strong bonds between the characters in Adventure Time.
One common theme is exploration. Characters often explore new places or relationships which are intertwined with sexual experiences. For instance, in many stories, the adventure might lead the characters to a new, exotic location where they engage in passionate encounters.
One great Ben x Kevin fanfiction could be about their adventures in a parallel dimension. In this story, they might face new aliens and challenges that test their friendship even more. Maybe they find a powerful alien artifact that only works when they combine their unique abilities, leading to a deeper understanding of each other.
You can often find such stories in some specialized literary magazines that focus on adult - themed or sensual literature. However, make sure to abide by the laws and ethics regarding the content.
Well, 'Fifty Shades of Grey' is a well - known one. It combines elements of eroticism and a certain kind of adventure in the relationship between the main characters. However, this type of story may not be suitable for all audiences.
One interesting storyline could be a female version of Ben having to deal with different alien cultures in the Omniverse in a more diplomatic way than Ben usually does. For example, she might use her charm and intelligence to resolve conflicts between warring alien species on a planet instead of just using brute force with the Omnitrix transformations.
One interesting concept could be creating new alien forms for Ben's Omnitrix that are unique to the fanfiction. Another might be exploring different relationships between Ben and his OC (Original Character) friends or foes. For example, an OC could be from a planet that has a very different culture from what Ben has encountered before, leading to interesting interactions and storylines.
Well, there's often an OC named Nova. She's usually depicted as having some sort of energy - based powers and being a friend or ally to Ben. Another popular one is Zephyr, who might be an alien - human hybrid with the ability to control the wind. These OCs are popular because they add new elements to the Ben 10 Omniverse.
Well, one common type of story might be about new alien forms that Ben discovers in the Omniverse. In lemon fanfiction, there could be a focus on the unique powers of these aliens in unexpected situations. For example, an alien with the ability to manipulate time might accidentally send Ben to a different era within the Omniverse, and he has to figure out how to get back while dealing with the local threats.
