Summary: A "Twilight Zone"-style fic where a woman finds herself in a strange little town where everything is too clean and perfect. It's mysterious and unnerving, and she is unable to leave for some reason. But things don't get really bad until she has to go to the bathroom. There are no toilets, because the people who live there don't need them. What's more, urination is a punishable crime, and defecation carries a more severe penalty. The ending could reveal that she's been shrunk and put in some child's magical playset, and the inhabitants are living dolls. Or maybe this is a community of robots, or a fake environment that aliens created for some reason. Or you can come up with your own twist ending.

Summary: A "Super Mario Bros." fanfic (there's currently no category for those). A warp pipe that's supposed to be supplying plants in a Toad park with periodic water starts behaving oddly. The water is supposed to come at certain times in the day, but instead it's more or less random; the amount of water each time is too small; and sometimes there's manure in it (it's assumed to come from some large animal, since it's in masses too huge for any Toad). Mario is called to the scene, and he traces the pipe to the source of the problem inside the huge labyrinth of pipes that exists in the Mushroom Kingdom (possibly encountering enemies along the way). It turns out not to be some sick Koopa joke, but instead a botched repair job that connected the irrigation pipe to a mysterious pipe instead of the water supply. Armed with a frog suit, Mario investigates this unidentified pipe, and it warps him into Princess Toadstool's toilet bowl. She was the source of the huge loads of feces, never knowing that they were making public appearances.

Summary: Some kind of magic or technology inverts switches an unfortunate female (or females') excretory and digestive systems, proportionally converting their urine production into feces and vice-versa. Huge dumps become large amounts of pee, and needing to poop happens as frequently has needing to pee normally would, so characters end up confused when they inexplicably need to do the opposite of what they've ingested (full stomachs create impossibly large bladders, and drinking plenty of liquids leads to lots of small dumps to make). To make matters worse, conditions like diarrhea and bedwetting turn into frequent urination and bed-pooping instead. Whether or not the problem is solved is up to you.

Summary: There's a technologically-advanced society where bodily functions are considered disgusting. So more of the people, or maybe just the aristocrats, have portals installed in their colons so their waste is transported into other people. There's some people in this society who are paid just to handle the disgusting chore that is defecation. When one of these "waste management" people poops, they poop several times their weight, because they're pooping for several people. Things can be really bad if they don't get to a mega-toilet in time. This could also work with magic instead of technology.

Summary:

(STYLISH FEMALE LEAD GOES HERE) will do anything to protect her sneaker collection. But a laundry day mishap spills shoe waterproofing spray on her clothes, and forces her to stand at her apartment's public laundry room sink holding her bladder while she soaks the permanently staining chemicals out in cold water! Eventually she yanks on a pair (or multiple pairs) of waterproofed (under)pants either on top of her current clothes, or changes into them, to keep her imminent mess to a minimum...

...and realizes how well they hold it all, too.

EDIT: I mean, have you seen the stuff? Just youtube "hat water repellent."

Summary: A girl wakes up late one morning and has to rush to class.  She rushes through her daily routine (washing, eating, drinking A LOT) and somehow gets to class before she would be counted late.  Unfortunately, as soon as the teacher closes the door, she realizes that she forgot to do the most important thing: pee.  To make matters worst, the teacher, a hard ass who does not allow students to leave the classroom for ANYTHING, is teaching a lesson on the digestive system.  Specifically, the urinary tract.  With all the references to fluids and bladder contractions, can the girl hold out until the end of the period?

Summary:

Lots of people have bedwetting problems in their youth, but they get over it. The main character in this story is no different, only hers comes back when she's a full-grown woman with a full-grown bladder. This is especially unfortunate because she's due to be married soon, and will be sharing a bed with a man for the first time in her life. Every night. She's desperate to cure her problem before the big day, and consults everyone from doctors and psychiatrists to psychics and Shinto priests. She can't remember how she overcame her bedwetting problem when she was a little girl, and she becomes convinced that, if she can remember that or find someone else who remembers, she can solve her problem again.

Summary:

A girl, or young woman, is on a date at a fancy restaurant.  She's all dolled up in her nicest dress, and the couple is having a nice romantic dinner.  But, something's wrong with this picture.  A strange rumbling feeling in her pit of her stomach - she has to poop.

The basic idea is there, make of it what you will.  Perhaps just a desperation story, where she holds it in despite the discomfort, and then finds relief when she's perched on her own private toilet.  Maybe she goes at the restaurant, and is mortified that her date would find out.   Or maybe a messing story, where she tries to hold it, and ends up ruining her dress and her perfect evening.
