There might be a bondgae story where a bondgae is on a quest to find a lost treasure. It has to overcome various obstacles like crossing a wide river and climbing a steep mountain. Along the way, it makes new friends who help it in its journey, and finally, they find the treasure which turns out to be a magical key to a new world.
Sure. There was a bondgae named Blippy. Blippy lived in a small village. One day, a big flood came. Blippy noticed that a little mouse was stuck on a floating log. Without hesitation, Blippy swam out to the log and brought the mouse back to safety. The whole village was so proud of Blippy's brave act.
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.
