Such porn comics are often against moral and legal standards, filled with potentially harmful and unethical content. It's best to stay away from them and focus on positive and meaningful forms of entertainment.
Sisters was the name of a TV drama. The drama was set in troubled China and told the story of the ancient town of Linglong in Yunnan. There were three forces in the play that kept each other in check, but a massacre broke the balance, leading to the story of a tea called Linglonggong. The series had a total of 30 episodes, of which episodes 18 and 30 were mentioned as highlights. Other than that, other information about the sisters, such as the specific plot and cast, was currently unknown.
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.
