None, she waits for the cleaning to finish

Nicole didn't want to risk her poop coming out while going to one of the other bathrooms, so she sat next to the bathroom door and waited for the cleaning to finish.

The cleaning couldn't last that long, right?

Nicole was fiddling with her fingers to distract her mind from her growing need.

After about five minutes, the cleaner came out of the bathroom and removed the cleaning sign.

Nicole immediately walked into the bathroom and got into the first cubicle.

"Good thing I waited" she thought.

And it was true, probably the other bathrooms would have a line to get in, so Nicole was lucky to find that void.

Nicole pulled down her panties and sat on the toilet. It didn't take long for her anus to open up and release the entire contents of her intestines.

After several minutes, Nicole had completely freed her intestines. But her stomach still hurt.

Nicole knew the diarrhea wouldn't leave her alone for the rest of the day, but at least she had managed to get rid of it a bit. And if she felt like shitting again, she hoped it would be before or after her next exam.

Nicole wiped herself with toilet paper, flushed the toilet, pulled up her panties, left the cubicle, washed her hands, and left the bathroom.

Her next exam was still almost an hour away, so Nicole had time to walk around the school for a while.
