Such stories are not acceptable. Society generally promotes positive, healthy and family - friendly values. Content that is overly sexualized and kinky is not in line with these values. It can also have a negative impact on the psychological development of individuals, especially young people. So, it is firmly rejected in a civilized society.
It depends on the context and the relationship between the couple. In a very private, trusting, and consensual relationship, sharing such stories might be a form of sexual communication. However, it should always be within the boundaries of respect and legality.
The legality of free kinky stories is a complex matter. Some stories that are considered kinky may simply be exploring unique or alternative relationships or ideas in a fictional and consensual way within the story. These may be legal. However, if the story contains elements that are against the law, like promoting illegal sexual acts or violating ethical boundaries in a non - fictional way, then it is not legal. Also, if the story is using someone else's copyrighted material without permission, that's also illegal regardless of its 'kinky' nature.
Kinky sex comics typically showcase a wide range of adventurous and taboo sexual acts. They might include things like unusual fetishes or intense power dynamics. However, it's important to note that such content may not be suitable for all audiences and should be consumed with caution and within legal and ethical boundaries.
