Diapered Over Top

Rainbow Dash and Applejack were sitting on the grass outside after a game of soccer. Rainbow was wearing a white T-shirt with a rainbow lightning bolt on it and skintight black shorts about halfway to her knees, but with no skirt over top. Applejack was wearing a white and green T-shirt and jean shorts. Both girls were sweating a lot and drinking lots of water.

"Hey Applejack," said Rainbow Dash. "Let's have a race to see who can jump over all those hurdles on the racetrack first! And the loser has to wear diapers for a week!"

"You're on!" said Applejack with a smile. "And no super speed, or I win by default."

"I could beat you without my super speed, and with both hands tied behind my back!"

Rainbow and Applejack got to the starting line, and ran around the track, jumping over the hurdles. In the end, it was Applejack who won. Both girls were dripping with sweat, so they each drank five bottles of cider.

Once Rainbow was refreshed, she soon realized what she would have to do. "Is there any way out of this?" she asked.

"Nope," said Applejack.

They stopped by Pinkie Pie's house, for they knew Pinkie would sometimes wear diapers for fun, or if she was watching a long movie in theaters.

"Pinkie, would you be kind enough to give us some diapers?" Applejack asked. "Rainbow Dash lost a race to me and we bet that the loser had to wear diapers for a week."

"Ooh, this is gonna be so funny!" said Pinkie. She quickly zipped back into the house and returned with a full pack of diapers, and handed them to Applejack.

"Thank you kindly, Pinkie," said Applejack.

"Wait till I tell everyone!" said Pinkie. She began texting as Rainbow and Applejack walked away.

Once they were at Applejack's house, Applejack put a diaper on Rainbow Dash over her shorts.

"What are you doing? Shouldn't they go on under what I'm wearing?"

"I think it'll be fun to try it this way," Applejack said with a blush and a smile.

Rainbow felt quite foolish. She looked ridiculous with a diaper over top of her shorts.

So, she and Applejack sat down and started playing some rounds of one of their favorite games. Soon, Rainbow forgot about her padded rear and was having fun.

Until she had to pee from all she drank while she was outside. "I have to go to the bathroom," she said.

"Then go," said Applejack.

Rainbow started to stand up to go to the bathroom, but Applejack stopped her. "No, I mean go in your diaper."

"With my shorts on underneath?"

"You got it."

Rainbow couldn't say she was all that surprised. She'd have definitely responded the same way to Applejack were their positions swapped.

"Now that you mention it, I gotta pee real bad," said Applejack, and she ran to the bathroom. Rainbow ran after her, hoping to get into the bathroom when she was done. As Rainbow stood outside the bathroom door, she could hear Applejack's stream splashing into the toilet very loudly. She whimpered, for it made her more uncomfortable. Usually she liked this sound, but it made it harder for her to hold it, thinking of the relief she so desperately needed.

Then the toilet flushed. When Applejack exited the bathroom, Rainbow tried to run inside, but Applejack stopped her and carried her over her shoulder with her hands on her butt. "No, you don't get to use the toilet for a week. You need a good spanking to remind you of that." Applejack sat down on the couch with Rainbow over her knee and spanked her repeatedly. Because of the diaper it didn't really hurt, but it still made it harder for Rainbow to hold it. Plus, it was a bit embarrassing to get spanked like this... but part of her did like it.

So they sat back on the couch, Applejack with an empty bladder, and Rainbow with a very full bladder. She fidgeted, and Applejack, realizing Rainbow would not do well at the games in her current state, put on the sports channel for them to watch some sports. As the hours went by, Rainbow's need to pee grew more and more urgent, and she fidgeted harder.

"I'm serious, I REALLY have to go!" said Rainbow.

"And I'm serious, your toilet is all around you," said Applejack.

Well, it wasn't like Rainbow would have said anything different to Applejack if Applejack had lost the race. As nervous as she was to have an accident with no way of preventing it, she also found it exciting as well. She held it as long as she could, but eventually, her bladder finally gave out. Rainbow peed herself, a loud hissing noise emanating from her as her stream soaked her shorts and was absorbed by her diaper, which turned yellow at the crotch and butt. She blushed and whimpered as she felt the warm wetness spreading through her diaper and her shorts underneath. Her tight gray boyshort panties were soaked.

Applejack also blushed and smiled. "That wasn't so hard, was it?"

Rainbow peed for over two minutes and sat there in her wet state. "I need to be changed," she said.

Applejack picked up another diaper. "Now lay down."

Rainbow lay on her back, and Applejack removed her wet diaper and put a new one over top of her wet shorts.

"I'm still wet," said Rainbow.

"But your diaper's dry until the next time you pee," said Applejack. She put Rainbow over her shoulder, patted her butt, and set her down on the couch.

...

That night, Rainbow climbed into the bed with Applejack. She was wearing her fourth diaper for today, having wet the second and third already, and her shorts had remained on the whole time. They pulled the covers over them and fell asleep.

Rainbow woke up really needing to pee at 2:00 in the morning. She looked over at Applejack. She was laying still and snoring. As quietly as she could, Rainbow got out of bed and tiptoed to the bathroom. Yes, her shorts had been peed in three times already, and Applejack would make sure it was more over the course of this week, but she thought she could sneak this one trip to the bathroom, and keep this diaper dry, at least for the night.

She had just reached for the bathroom doorknob when Applejack grabbed her from behind. "Surprise!" She carried her over her shoulder again, going into the garage to get some rope. "I knew you'd try somethin' like that, but I was gonna give you a chance."

Rainbow groaned. Applejack slapped her butt a few times, then grabbed some rope and tied Rainbow's feet together. Then she set her down. Rainbow tried to stand up but fell on her butt. Applejack grabbed Rainbow's arms and tied them behind her. "There, now you can't sneak to the bathroom overnight, and I'll have to do this every night now." Applejack set Rainbow on her side in the bed, then climbed into bed, pulled the covers over them, and before long, fell asleep.

Rainbow couldn't sleep because she had to go to the bathroom really badly. She held it as long as she could, even though she should have known it was useless at this point, and ended up peeing herself again. About fifteen minutes later, she finally fell asleep.

She woke up the following morning to Applejack. "Rise and shine, Dash!"

"I can't. You tied me up so I couldn't get out of bed and use the bathroom, and I wet myself again."

"Right. Well, take your morning pee and then I can change you."

Rainbow sighed and peed her already-wet shorts and diaper. Applejack untied and changed her, again leaving her wet shorts on, which were beginning to stink far worse than the sweat from yesterday.
