In the 'Ben 10' series, Ben Tennyson is the main character. He has a device called the Omnitrix which allows him to transform into various alien forms. Gwen Tennyson is Ben's cousin. She also has magical abilities and often teams up with Ben in their adventures.
I'm not entirely sure specifically as it could vary greatly. 'Fanfic' stands for fan fiction, which is often written by fans of the 'Ben 10' franchise. It might focus on female characters from the series, perhaps exploring their backstories, relationships, or new adventures in a way that the official content might not have fully delved into.
Well, in a Ben Ten love story, Ben could be smitten with a girl from his school who has no idea about his secret identity as a hero with the Omnitrix. He has to balance his normal life with her and his life as Ben Ten. At first, he's really clumsy around her, not knowing how to act. But when she gets into trouble one day, Ben uses his powers as Four Arms to protect her. This is when she starts to suspect there's more to Ben than meets the eye, and their relationship takes an interesting turn.
The main distinction of porn with a story genre from regular porn is the presence of a coherent narrative. Regular porn often jumps straight to the sexual action, while the story genre tries to add some kind of story framework around it. But in the end, both are adult-oriented and feature explicit sexual content.
Well, it's hard to say for sure. The concept of 'porn-like' is quite subjective. Some might consider certain novels with excessive sexual descriptions as such, but it depends on individual perspectives and cultural standards.
In many places, 18+ porn comics are considered illegal. This is because they can have a negative impact on society and violate moral and legal standards.
