A possible plot could be that the girl is in a strange, magical world where she encounters the big monster. At first, she is terrified, but as the story progresses, she discovers that the monster has a kind side. Maybe the 'lick' could be a form of the monster showing its affection in a very odd, non - human way.
It could be a horror - themed story where the girl is in a strange place and the monster with a terrifying face approaches her and licks her as a sign of its menacing nature. This might lead to her trying to escape or find a way to defeat the monster.
It depends on how it's written. If it's written in a way that is not offensive or inappropriate, for example, if it's more of a fantastical and innocent exploration of an odd relationship, then it could be appropriate. However, if it has any elements of inappropriate behavior or is written to be disturbing, then it's not appropriate.
I'm not sure if there is specifically a 'dog monster face lick girl' in fanfic. Fanfic can cover a wide variety of strange and unique concepts, but this seems rather unusual. It would depend on the very specific and often out - of - the - ordinary fanfic communities and their creations.
In a fanfic, the girl could be visiting a Pokemon sanctuary. There, she encounters an Arcanine that has been rescued from a difficult situation. The Arcanine, sensing the girl's kind heart, approaches her and licks her face. This simple act could lead to a story where the girl volunteers to help take care of the Arcanine. She spends time with it, trains it gently, and they develop a deep bond that helps the Arcanine overcome its past traumas.
One possible plot could be that a girl gets lost in the forest and is found by a werewolf. Instead of harming her, the werewolf is curiously drawn to her and gently licks her face as a sign of an unusual connection. The girl, at first terrified, gradually realizes the werewolf has a kind of protective instinct towards her and they form an unexpected bond.
Perhaps it's a story set in a modern - day world where Cerberus is somehow brought into our reality. The girl might be a veterinarian or an animal lover who is not afraid of Cerberus' intimidating appearance. The face - licking could startle her at first but then she realizes Cerberus means no harm. It could be a story about breaking barriers between the human and the mythical.
In a 'dinosaur face lick girl fanfic', perhaps the girl is a time - traveler. She lands in the dinosaur era and is initially scared. But one dinosaur, which is different from the others, approaches her gently and licks her face as a sign of acceptance. The story could then revolve around her adventures with this dinosaur in that ancient world.
It could be a very strange and surreal concept where perhaps a dog - like monster has some sort of odd interaction with a girl, like licking her face. But this is really a very far - fetched and not a typical fanfic scenario. It might be used in a horror - themed fanfic to create a sense of unease or in a really wacky, experimental piece of writing.
It could be about a unique encounter in the RWBY universe where a character with a wolf - like face has an unexpected interaction with a girl. Maybe it's a sign of friendship or protection, like the wolf - face character is using licking as a way to show comfort or mark the girl as someone under their care.
One possible plot could be that the girl is an alien researcher. The alien dog, which has a unique face, forms an unexpected bond with her. It starts by licking her as a sign of affection, and they go on adventures together in an alien world, facing various challenges and learning about each other's species.
