It is not appropriate as it involves private and rather embarrassing bodily functions. Such stories can be considered invasive of a woman's privacy and not respectful in most social and cultural contexts.
How about a fanfic where a girl is building a solar - powered car? It shows innovation, determination and can be inspiring for readers, rather than the inappropriate content of the original.
Just be aware of what is appropriate. Think before you speak. If it involves someone's private and potentially embarrassing bodily functions, don't share it.
A 'peeing visual novel' is a type of visual novel that may involve themes or storylines related to urination in some way. However, this is a rather unusual and specific concept within the realm of visual novels.
Once upon a time, there was a little puppy. One day, while it was playing in the yard, it suddenly had the urge to pee. It ran around looking for a suitable spot. Finally, it found a corner near a big tree and happily peed there.
A funny peeing story could be about a cat. The cat saw a dog marking its territory by peeing on a post. So, the cat, trying to be funny, went to the same post and tried to pee on it too. But it was so funny because cats don't really mark territory like dogs in that way, and it just ended up looking really confused.
In a shopping mall, a girl suddenly felt the urge to pee. She had to ask the store clerks for directions to the nearest restroom. Once she found it, she went in and peed, feeling much better afterwards. It's a common experience that many girls can relate to.
I don't know the specific little girl you are referring to. But if we were to create a story, it could be that the little girl was playing in the park and got so engrossed in her play that she didn't realize she needed to pee until it was almost too late. She then had to run to the nearest restroom.
