Of course it's normal. Our bodies, whether male or female, are constantly digesting food. This process involves the breakdown of various substances, which can lead to the formation of gas. Girls have a digestive tract that functions in a similar way to that of boys. Farting is simply the body's natural way of expelling this gas. It's a common and healthy part of the body's normal operation. So don't be embarrassed or think it's strange when a girl farts.
Well, 'fart fiction' might be some sort of creative and rather odd concept. It could be a form of humorous storytelling where farts play a central role, like characters having special powers related to farts or farts causing strange events in the fictional world. Maybe it's a new and experimental type of short - story or even a performance art concept in a fictional sense.
Once upon a time, there was a little diaper girl. One day, she was playing happily in the nursery. All of a sudden, she felt that familiar urge. Her face turned a bit red as she started to poop in her diaper. Her mother soon noticed the smell and came over with a warm smile. She gently changed the diaper girl's diaper, and the little girl went back to playing as if nothing had happened.
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.
