There are so many other positive and creative ways to write fanfiction, like exploring their friendship, adventures, or character development without delving into inappropriate sexual content.
Simon, if he makes an appearance in the fanfiction, would have a very different dynamic with Marceline. He has a long history with her and his wisdom could play a crucial role in helping her understand and manage her 'vampire in heat' situation. His presence could also bring up a lot of memories for Marceline, which would add depth to the story.
A theme could be the relationships around Marceline. For example, how her friends or love interests react to her being in vampire heat. They might try to help her control it or be in danger from her if she loses control. Also, there could be themes of self - discovery as Marceline learns more about this aspect of her vampirism.

In fanfiction, their relationship could be developed by having them team up for a noble cause, like saving the Candy Kingdom from a new threat. During this mission, they face challenges that require trust and cooperation.

Also, they could have a friendly competition that turns into a deeper understanding of each other's strengths and weaknesses.
A Marceline and Finn kiss in fanfiction can be really interesting. It might show a different side of their relationship.
