Fluttershy was sitting in class, paying as close attention to the lesson as possible.

However, she was fidgeting slightly, for she was very uncomfortable. She had to pee really badly, and she had held it in all the previous class.

All she had to do was raise her hand. The teacher would then call her name, and Fluttershy would say she had to go to the bathroom. Every time Rainbow Dash, Applejack, or Pinkie Pie had done this told her that the teacher would definitely let her go and get her much-needed relief.

But Fluttershy was too shy to say she needed the bathroom. It was something she just couldn't do. This often resulted in many accidents during class, and she'd spend the rest of the day in a wet dress and panties. It happened so often, not to mention how prone she was to fear wettings, that she was used to it. Not that it wasn't still embarrassing enough for her to blush every time, but only mildly so. Besides, none of the other students made fun of her for it. Well, except Sunset Shimmer, but that was the old Sunset, the new Sunset was as compassionate as any of her other friends, and had even shared a story of how she had wet her panties while trying to get used to this world, which made her feel a bit better.

Even Rainbow Dash, a tough girl who had probably never wet herself in her life, and who Fluttershy had a huge crush on, still liked Fluttershy even after witnessing multiple pee accidents and knowing she was a chronic fear wetter. Maybe she even liked her as more than a friend. She really appreciated her for that.

But she still preferred to avoid wetting herself whenever possible. Well, except in her wetsuit when she was in the water, but people pee in their wetsuits all the time without it being considered disgusting or weird.

Pinkie Pie had a few accidents from time to time. Sometimes she just drank too much and didn't make it, other times a full bladder coincided with her laughing too hard at something. But Pinkie was "weird" enough that she could do anything like that without anyone batting an eye, and would always laugh it off, and even so, her accidents were far less frequent than Fluttershy's.

But still, she'd rather take her chances with her full bladder than the embarrassment of asking to use the bathroom. She knew deep down it didn't make sense that she found wetting herself less embarrassing than saying she had to pee, but that's just how it was. At least for the wetting, all she would have to do was hold it until lunch, and if it happened, it happened, and she did all she was comfortable doing to prevent it. Besides, the one time she had actually tried to muster up the courage to ask to go to the bathroom, she had ended up peeing herself out of nervousness.

As Fluttershy fidgeted in her seat, the sky outside filled with dark clouds and it started to rain hard. The sound of the rain made it even harder for Fluttershy to hold it. She crossed her legs and fidgeted even harder.

"Is everything all right, Fluttershy?" the teacher asked.

Fluttershy blushed. "Yes," she said. She looked at the clock. It was 20 minutes until the end of class. If she could just hold it this long.

As the minutes went by, Fluttershy continued to hold it, and her need to pee grew more urgent. The minutes went by so slowly, and the rain kept coming down, but Fluttershy was determined to make it this time.

During the last five minutes of class, Fluttershy was trying her hardest not to fidget, to hide how desperate she really was.

After what felt like forever, the bell rang for lunch. Fluttershy stood up and ran as fast as she could towards the nearest bathroom. She really needed to go but she had a feeling she might make it this time.

Just then, there was a flash of lightning visible out the windows. Fluttershy slowed down a little, nervous at what was to follow.

A few seconds later, a loud, booming crash of thunder was heard. Fluttershy let out a squeak, stopped in her tracks, and started peeing full force. She trembled for a few seconds as pee ran down her legs, soaking her socks, filling her boots, and forming a puddle where she stood.

Trixie walked by. "Oh, Fluttershy's peeing herself again," she said casually, and walked towards the vending machine, as if it was no big deal.

It didn't take Fluttershy long to get over her fright at the thunder. But as soon as she did, she became aware of the warm wetness spreading through her pink panties and flowing down her legs. She blushed, and let out a sigh of dismay. She didn't make it. She had wet herself yet again. Sometimes she got the feeling she peed in her panties more than in the toilet, even though there had been many times she had made it.

When she finished peeing, she was standing in a massive puddle. The front of her green skirt was soaked. It was obvious to anyone who walked by that she had peed herself.

"Cleanup on Aisle 3!" The Cutie Mark Crusaders called.

As the janitor arrived with a mop, Fluttershy walked to the cafeteria, her boots making squishing sounds with each step, and sat down with her friends. "I didn't make it," she said, still a little red in the face. "I had another accident in my dress."

"Was it because of the thunder?" Rainbow asked.

Fluttershy nodded.

"I'm sure you would have made it otherwise." Rainbow patted Fluttershy gently on the back, and Fluttershy felt better as usual. Rainbow always had a way of cheering her up, even though her accidents had stopped being mortifying long ago.

They ate their lunch and made casual conversation, in which Fluttershy's accident didn't come up again, and Fluttershy mostly forgot it, aside from how wet she was. She did notice Rarity looked a little uncomfortable, as if she needed to pee as well, but dismissed it.
