Sunset Shimmer stood at the Canterlot High school grounds. She watched her demon self erase the five friends she had driven apart one by one, before advancing on Princess Twilight Sparkle. Twilight backed away and fell on her butt. Demon Sunset advanced towards her.
"Stop!" said Sunset.
Demon Sunset turned towards her. "You can't stop this," she says. "This is the real you! You will always be me!" She turned towards Twilight to blast her...
...and then Sunset woke up, breathing heavily. She was relieved that the whole thing had been a dream. But she remembered it had been based off the events of yesterday. She felt terrible just thinking about it.
Then she noticed her pajama pants were wet. At first she thought she was sweating a lot, but her pajama shirt was dry. She pulled back the sheets to see it was mainly her crotch and butt that were wet, and part of the mattress was wet only around where this area of her would be while she slept. Between this and the smell, there was no doubt about it. She had wet the bed.
"No... how could this happen? I've never wet the bed before." Sunset sat with her arms wrapped around her knees, trembling for a bit. Was this all a side effect of her evil side being blasted out of her? She took a deep breath and tried to think. Was this the Elements' way of punishing her for her past? No, she thought. Ponies seemed more forgiving than humans. Once the Elements reformed someone, they were free to start over. It was probably a result of the nightmare, it was so vivid and frightening for her, beyond any of her worst nightmares.
She confirmed this in only a few days. The following night, she did not have a nightmare and woke up dry. But the night after, she once again had a nightmare about her demon transformation and woke up wet. There was no doubt about it. It was the nightmares. Maybe all she had to do was wait it out. Once the nightmares were gone, so would her bedwetting problems.
But her nightmares never seemed to go away. At least five days a week she would wet the bed. It got to the point where she would stop washing her pajama pants, except with the rest of the laundry.
Then one day...
"Hey Sunset," said Rainbow Dash. "We're having a sleepover at my house. You wanna come with us?"
"What?" Sunset felt very nervous. A sleepover with her new friends, who had only just forgiven her at a princess's request, was out of the question. If they found out she wet the bed... "I couldn't. Not after what I've done."
"We've forgiven you," said Fluttershy.
"Twilight wants us to be your friends and teach you all about friendship, and we're not gonna let her down," said Rainbow Dash.
"Um... but I snore."
"So does Rainbow Dash," said Applejack.
"I... don't have a sleeping bag."
"I can make one for you," said Rarity.
"Uh..." Sunset was sweating profusely now. "How do you know I won't do really bad things to you while you sleep?"
"If you were gonna do that, you wouldn't be sayin' this," said Applejack. "Plus I think you really want a second chance. What's up?"
"I can't tell you. If I did, you wouldn't want to be my friends anymore."
"Try us," said Rainbow Dash. "It can't be worse than turning into a demon and trying to destroy us."
"Rainbow Dash!" said Applejack.
"No, she's right," said Sunset. She took a deep breath. "More often than not, I have nightmares about turning into a demon, and whenever I do, I..."
"Yes?" the other five girls asked.
Sunset took another deep breath. "I wet the bed." She blushed beet red.
For a moment it was silent. Then...
"All right, so I'll make a rubber sleeping bag for you," said Rarity.
"For a moment I thought it'd be something like you turning into a werewolf or a vampire or something," said Pinkie Pie.
"I'm pretty sure she doesn't," said Rainbow Dash.
"Why not? We just found out magic is real and that she's a talking unicorn pony who turned into a human when she came from another world."
"Wait," said Sunset. "You don't have a problem with this?"
"Not at all, sugarcube," said Applejack.
"And you're not making fun of me?"
"We might laugh down the road, but only when we know you're comfortable with it," said Rainbow Dash.
"I really hope it stops, and that if it doesn't, that you can feel better about it," said Fluttershy.
"I... didn't expect this reaction," said Sunset. She really did have much to learn about friendship.
"Besides," said Fluttershy. "I wet the bed sometimes." She blushed lightly.
Sunset wasn't all that surprised, but she didn't say this, for she didn't want to be insensitive.
"Me too," said Pinkie. "Sometimes when I drink lots and lots of soda before bed. Or sometimes when I just don't feel like getting up." She giggled.
Did Pinkie just say she deliberately wet the bed sometimes? Well, she was Pinkie, she didn't really count. Sunset said "Sounds like you don't mind, Pinkie, but I'm really sorry to hear that, Fluttershy."
"It was really embarrassing at first," said Fluttershy, "but my friends were so sweet about it and I'm used to it now."
"And sometimes I have a lot to drink before a soccer game that goes on for hours because we stay tied," said Rainbow Dash. "The first time I lost out of embarrassment, but the fans still loved me, and cheered for me when I won every time after that, as if I had never wet myself, even though they had to have seen it. Or maybe they couldn't tell cause my shorts were black."
"One time I was workin' so hard I refused to stop for a bathroom break, and ended up wettin' mah jeans," said Applejack.
"Well..." said Rarity. "Don't ever tell anybody else, but I never use the school toilets. So I have to hold it all day. Sometimes I make it home, sometimes I don't." She blushed lightly.
"I had no idea," said Sunset. "I'm glad the old me never found out."
"So rest assured you're not the only wetter here," said Rainbow Dash.
Sunset considered bringing up the first two times she had peed after arriving in this world. The first time she wet her panties because she didn't know she was wearing them under her skirt, as they didn't have panties in Equestria. The second time, she simply couldn't get them down in time because she was unused to having hands. But she kept quiet about this because she was sure Twilight had to have gone through the same thing and didn't want to reveal this to them behind her back. It was along similar lines she never tried to expose or make fun of Twilight for it, for fear that Twilight would tell the school that she had done the same thing. She was glad she made this decision, she felt bad enough for driving her new friends apart as it was.
...
They had a lot of fun at the sleepover. Sunset was hoping her nightmares would go away after such a fun and relaxing night with her friends. She climbed into the sleeping bag Rarity had made, which was lined with rubber on the inside, and went to sleep.
At first she slept peacefully, dreaming of the fun they'd had at the sleepover. But then, her demon self entered and erased all of them before engaging Twilight in a brutal fight. Sunset tried to intervene but the demon tied her up with magic strings. She had to go to the bathroom really badly and ended up peeing herself.
She woke up in her sleeping bag. As expected, her pajama pants were wet, but the sleeping bag hadn't leaked on the floor. Rarity had designed this well.
The other girls were awake already. "Morning, Sunset," said Applejack.
"Good morning, girls." Sunset blushed lightly.
"We heard you peeing in your sleep," said Pinkie. "So you can come out. We don't mind, and we won't laugh till you're all right with it."
Sunset climbed out of her sleeping bag, and the girls got a view of her wet pajamas. She blushed a little.
"No need to feel ashamed," said Rarity. "Like I said, we all wet ourselves from time to time. Why don't you have a nice shower and get changed?"
Sunset felt a lot better as she walked to the bathroom.
...
The next time she wet her sleeping bag, she laughed it off with Rainbow and Pinkie, though she still kept having the nightmares.
However, after her defeat of the Dazzlings, the nightmares went away and she never wet the bed again - unless Rainbow or Pinkie put her hand in hot water on a sleepover, which she would find to be a funny prank, and much less unpleasant than the nightmares.
