The one on the third floor

It was the furthest option, and probably the least suitable for her situation. But she had a hunch that the bathroom on the second floor was full, and the one on the other side was not very reliable.

So, squeezing her buttocks, Mai hurriedly ran to the stairs.

The climb to the third floor agitated her intestines greatly, and she was still on the stairs. Specifically, halfway up the stairs leading to the third floor.

Mai was holding her stomach in pain. Her farts had been too wet, to the point where she felt something wet in her panties, and she didn't even want to check if it was poop or sweat. Mai felt like she was going to explode. Mai was holding her stomach in pain.

But no. She had to move on. She did not lack much, she only had to run a couple of meters and right there would be the bathroom door.

Mai took a breath and ran upstairs, trying not to trip over, because if she did, it would definitely be the end of her school life.

Luckily for her, she managed to climb up without incident, and without even stopping to breathe, she ran to the bathroom.

She walked into the first empty cubicle she found. Her haste and desperation were such that she didn't even bother to lock the door, just closed it a little and dropped into the toilet.

Her thunderous farts were the first thing that came out, to make way for her mountain of poop.

Mai breathed a sigh of relief when she finally broke free, and it didn't take long for her bladder to join in the relief as well.

After completely freeing herself, Mai wiped her butt, pulled up her panties, pulled the toilet chain, and walked out of the bathroom.

"That was very close" Mai thought.
