I'm not entirely sure as this seems like a very specific and rather inappropriate or at least odd topic. Fanfic usually refers to fan - created fictional stories. But this particular description involves inappropriate and unhygienic elements that are not suitable for in - depth exploration.
Typically, no. Our bodies are designed to hold urine until we reach a suitable place to void. When a girl pees herself during tickling, it could be due to a number of factors. It might be that she has a weak pelvic floor, or there could be a problem with the nerves that control the bladder. But just from the story's perspective, it could also be an exaggerated comical element.
No. It is not a common type of fanfic at all. Most fanfic focuses on positive aspects like character development, relationships, and exciting plotlines. This description involves rather unappealing and inappropriate content that is not typical in the fanfic world.
One reason could be a weak bladder sphincter. If it's not strong enough, the pressure from laughing during tickling might cause involuntary urination. Another possibility is that she has a very sensitive nervous system, and the tickling stimulates the nerves in a way that disrupts the normal control of the bladder.
Once there was a girl named Lily. She was on a long road trip with her family. Unfortunately, she suddenly felt the urge to pee but there were no rest stops in sight. Luckily, she had a pee pad in her bag which she had for emergency. She discreetly used it in the back seat of the car while her family was chatting and listening to music, and it saved her from an uncomfortable situation.
Yes, there could be. For example, in some children's books about potty training, there might be a story where a little girl has an accident and pees in her diaper. It can be used to teach kids about the process of growing up and learning to use the toilet.
Sex fanfic is a form of creative writing that often tries to depict sexual relationships in a way that is both exciting and somewhat idealized. The scenario of a guy peeing accidentally is not something that would enhance the sexual or romantic elements. It's not a common element because it goes against the common aesthetics and themes of sex fanfic, which tend to be more about attraction, seduction, and mutual sexual experiences.
