I think a better approach would be to write a fanfic that focuses on the deep emotional connection between Superman and Wonder Woman without the 'lemon' elements. Their relationship could be explored in terms of mutual respect, shared values, and their roles as superheroes. This way, it can still be an interesting and engaging story while maintaining the integrity of the characters.
The Wonder Woman comic has a long history. It debuted in 1941 and has continued to evolve and captivate readers over the decades. So, it's been around for more than eight decades.
