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.
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.
I recommend I'm Really a Doctor. Although it's not a comprehensive British and American novel, it's a suspense-mystery-mystery novel. The female protagonist works in a psychological clinic that only opens at midnight and is good at solving all kinds of strange cases. Although the female protagonist didn't describe the ability of the camera, the plot of this novel is quite interesting. I believe you will like it. I hope you like this fairy's recommendation. Muah ~😗
