Twilight and Fluttershy walked over a hill and could see all of sweet apple acres before them. The sun was resting at the top of the barn a sign that the day was coming to a close. Twilight was beginning to waddle as her diaper had become uncomfortably wet. Seeing this Fluttershy quickly made her way to the farm Twilight following behind her. They approached the barn, the doors were wide open and Applejack was talking with Rarity inside. Fluttershy quietly knocked on the barn door interrupting Applejack and Rarity's conversation.

"Oh Fluttershy," Applejack said surprised. "I forgot you were coming today. Ya'll give me a minute to get yer critter food ready."

"Oh that's fine," Fluttershy said politely. Twilight tapped Fluttershy on the shoulder anxiously. "Oh if you don't mind do you think we could go somewhere private so I can change Twilight's diaper."

"Fluttershy!" Twilight yelled embarrassed. Rarity and Applejack giggled.

"You can use the barn," Applejack said leaving. Rarity didn't take the hint and remained in the barn. Twilight and Fluttershy looked at her expectantly. After a few seconds of this Applejack return quickly ushering Rarity out of the barn closing the door behind her.

"What!" came Rarity complaining from the other side of the barn.

"I wonder what Rarity's doing here?" Twilight pondered.

"We can ask her later," Fluttershy said removing the disposable diaper she had stored under her hat. She then helped Twilight free her legs from the romper she was wearing and gestured to a nearby hay bale. "I don't have anything to tie your little hoofsies with so you're just going to have to behave ok," Fluttershy said as she removed a pacifier from under her hat and stuck it in Twilight's mouth. Twilight peacefully started suckling the pacifier as Fluttershy changed her soggy diaper. The disposable diaper wasn't as thick as the cloth one Twilight was wearing for most of the day but it would be fine until they returned to Fluttershy's cottage. After Twilight was changed Fluttershy wrapped the wet diaper discreetly inside the diaper cover and tied it around her body so that it hung off of her left flank. While she was doing this Twilight managed to get back into her romper. The two emerged from the barn Rarity was waiting next to the door.

"Hello girls," Rarity sang. "Been having fun today?" Rarity asked coyly. Twilight blushed.

"Oh we have," Fluttershy said cheerfully. "And my little baby was a big helper today." Twilight was now deeply blushing.

"I bet she was," Rarity said pinching Twilight's cheek. The combined affection from the two of them was making Twilight grow increasingly shy. "You should let me foalsit some time you know." Fluttershy and Twilight looked a little unsure at this prospect. "Oh it's fine if you don't want to," Rarity said beginning to add drama. "I'm just so alone with no special somepony to play with, I just want to try it, just once." To finish her dramatic scene Rarity began forcing herself to cry. Fluttershy and Twilight looked at each other neither of them buying Rarity's act. As Rarity continued to sob though Twilight spoke up.

"I don't mind I guess," Twilight said clearly unsure. "It's up to you Flutters."

"Oh well if you're ok with it," Fluttershy said attempting to shift blame.

"Well you don't have to leave it up to me. You can say no," Twilight said hopefully.

"Oh no I couldn't. If if you want to let Rarity foalsit then I won't stop you." Rarity was beginning to get annoyed at the constant blame shifting.

"Can somepony give me a yes or no sometime today," Rarity said annoyed. Twilight spoke up.

"I guess you could be my foal sitter." Twilight said hesitantly.

"Hooray," Rarity said hugging Twilight. "Ever since you two starting dating I've been dying to try it. It just looks like so much fun. Unfortunately opening with that at speed dating has gone over well, but now I don't have to worry about that."

"You know it is fun but it's also a lot of work," Fluttershy said while attempting to free Twilight form Rarity's embrace.

"Well of course I know that," Rarity said seriously. "But don't worry I didn't open up three successful fashion stores without being able to handle some hard labor. I'll do my best, and if I have any questions I know just the pony to ask," Rarity said comfortingly.

"Ok," Flutteshy said a little more confidently now. "We'll get together later and work out a date and I'll send Twilight over."

"Oh yay!" Rarity said embracing the two ponies in a hug. Applejack had just returned from the field carrying three large sacks on her back.

"What did I miss?" Applejack asked curiously.

"Oh Applejack I'm going to be a foal sitter," Rarity said happily. Applejack looked at Twilight and Fluttershy who shrugged their shoulders innocently.

"I guess I'm happy fer you," Applejack said unsure. "Just don't fill me in on any of the fine details alright. Anyway I got yer critter feed Fluttershy. Be careful these bags are real heavy."

"Twilight do you mind helping?" Fluttershy asked seriously.

"No problem," Twilight said as she lifted one of the sacks on to her back magically. She then lifted the remaining two on to Fluttershy's back who grunted from the weight. "You got it?" Twilight asked concerned. Fluttershy continued to struggle so Twilight instead placed the extra bag on to her back instead. The extra weight caused her to briefly loose her balance but Twilight found that if she distributed her weight a certain way she could manage it. Fluttershy lovingly kissed Twilight on the cheek as thanks.

"Well we should be going," Fluttershy said concerned for Twilight.

"You be careful now ya hear," Applejack said concerned.

"Don't worry I got it," Twilight said confidently. "I got a bunch of extra muscles when I grew my alicorn legs," Twilight joked. With that Twilight and Fluttershy quickly began making their way back to Fluttershy's cottage.

After a few minutes of walking Twilight spoke up. "Oh shoot," Twilight exclaimed. "We never asked Rarity why she was over there."

"Oh she was showing Applejack her dress for the gala. I saw it in the back of the barn while I was changing you. I didn't want to say anything about it though." Fluttershy said.

"Really, Applejack's actually going to wear one of Rarity's new dresses." Twilight exclaimed.

"I guess so," Fluttershy said. "She was probably too embarrassed to say anything about it, it looked like it would fit her well though."

"It's kind of adorable that's she's embarrassed about it," Twilight said giggling. She tripped a little because she was laughing too much.

"Are you sure you've got that dear?"

"No I need you to take it the rest of the way," Twilight said as she moved the extra sack onto Fluttershy's back. Twilight gave an exhausted sigh. "How did you do this on your own?"

"Well usually I'm not tired from looking after a little one all day."

"Oh sorry."

"Don't be sweetie. I love taking care of you, and besides you're here to help me out now so it all worked out."

The two made their way back to Fluttershy's cottage in loving silence. Once they arrived Twilight and Fluttershy dropped the sacks they were carrying near the front gate to Fluttershy's cottage. "I should probably head home tonight," Twilight said tired. "I probably have a lot of princess paperwork to take care of."

"Oh ok," Fluttershy said, "I'll talk to you tomorrow dear." Fluttershy called out as Twilight walked toward her castle.

"Ok love you babe!" Twilight shouted as she walked out of Fluttershy's sight. After a quick walk Twilight made her way to her castle. A small note on the door told her that Spike had already came and went. Twilight assumed the Spike found whatever books he needed and thus didn't look at the note in much detail quickly throwing it in the trash as she made her way inside. Twilight had correctly assumed that she would have work to do. When she walked into her office she noticed the small pile of paper left on her desk, no doubt something from princess Celestia. Working on this took Twilight the rest of the night. Once she finished she stumbled into her room exhausted and hastily removed the romper she'd been wearing all day and fell down on her bed limp.

Twilight awoke the next morning groggily rubbing her eyes. She made her way to her bathroom to take care of her mane which had become mangled in her sleep. As she was brushing her mane she noticed the she forgot to take her diaper from yesterday off. This didn't particularly bother her, she usually ended up wearing a diaper to bed more often than not these days so she didn't pay it any mind, she just made a note to get out of it whenever she found the time. It was only after she continued to move around that she noticed something off. Her diaper was wet, and to the best of her knowledge she didn't do that while she was awake last night. Twilight's face grew dim as she thought of the consequences of this. Despite the fact that Fulttershy wasn't around Twilight decided to change into a new diaper, given that this was the second night in a row that this had happened she didn't trust herself without it.
