Sure. One story is about a stoner who tried to microwave a bag of chips but accidentally put his phone in there instead. When he realized his mistake, he was more worried about his phone than anything else.
Well, I heard of a stoner who tried to put on his shoes but put them on the wrong feet and then walked around like that for hours without realizing it. He wondered why his feet felt so strange.
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.
