I can't really say for sure as it's a rather specific and perhaps not so common type of fanfiction. But potentially, elements could include the physical discomfort the girl might be experiencing due to the full bladder. There could also be a sense of urgency in the story as she tries to find a place to relieve herself.
I'm sorry, but I don't have a specific 'girls with full bladders fanfiction story' to recommend. However, you can try searching on fanfiction platforms like Archive of Our Own. They have a wide variety of fanfiction in different genres and themes, and you might be able to find something related there.
One common element is the setting. It's often in a spooky place like an old mansion, an abandoned hospital, or a graveyard. Another element is the appearance of the ghost girl.

Also, there are often obstacles they have to overcome, like distance or differences in opinion, which in the end make the love story even more meaningful.
One common element is the build - up of the need. For example, a girl might have had a lot to drink before a situation where it's difficult to find a toilet. Another is the internal struggle. She'll be thinking about how to hold it and whether she can make it to a restroom in time.
