Rainbow and Applejack reassure the CMC

“It’s not fair,” Rainbow Dash protested, her arms crossed with a foul scowl on her face. They were both in the train car back to Ponyville with the rest of their Mistress’s bags and whatever else she or their Master had decided to bring back from the Crystal Empire. Twilight and the others would follow as soon as they set up a temporary government in the Crystal Empire whilst Cadence and Gleaming were away.

During the entire time, Rainbow Dash had been complaining, not about the work of course. She was the Element of Loyalty after all, and no work would ever bother her if it was for their Master and their Mistress. No, she had a different problem that Applejack had to agree with.

“Master dragged us all the way over to Crystal Empire and he didn’t even need to fuck us once. We didn’t get the chance to expand his harem either,” Rainbow said with her arms crossed as the train rattled along into Ponyville. “We might as well have stayed here.”

“I feel ya partner… ah’m feeling right anxious to have our Master ram his big damn cock into mah ass, but it ain’t the place of a **** to demand anything of her betters,” Applejack reminded her, wrapping an arm around her girlfriend’s neck. “So let’s just do what they want and ah'm sure they’ll want to fuck us soon. Ah mean I wouldn’t want to miss a big beautiful ass like yours.”

She highlighted her point by groping Rainbow’s rear earning herself a lewd kiss. Soon though the train came to a stop, and the two lovers broke from their kiss and made their way out of the train. As they stepped onto the platform they found two ponies running up to them.

The first was Applejack’s sister Applebloom. Like her sister she had quite a bit of muscle on her and whilst not the Amazon Applejack was, in fact she was on the shorter side, she still had a noticeable rack.

Behind her was Scootaloo, Rainbow Dash’s surrogate sister. By far the most petite of the three crusaders she was similar to Rainbow in that respect. And just like Rainbow she also had a pretty fine ass too, one that they knew Spike would appreciate.

“SIS, SIS!” Applebloom yelled running up to the two sisters, her eyes wretched with concern. “We got a problem.”

The two crusaders crashed into their respective sisters, wrapping their arms around their waists. “Calm down there girls. What’s got you two in a huff?”

“It’s Rarity.”

“And Sweetie Belle.”

“They’re- they’re…”

“They’re fucking!”

Rainbow and Applejack looked at each other, Rainbow looked as if she could burst out laughing but Applejack was frowning. Whilst she of course had no issue with their Mistress fucking her personal sex **** she did worry about what would happen if the two girls went around blabbering about.

“Now want in tarnation would make you say that?” Applejack asked her sister, her mind thinking ahead about what to do next. Applejack didn’t like lying but her friends were counting on her.

“We saw her,” Applebloom confessed but hesitated before speaking and her eyes shifted to the ground as Applebloom tended to do when she was nervous.

Rainbow seemed to pick up on the nervousness as well as her voice immediately became predatory. “You saw her? Were you perving on her?”

“No!” Applebloom squealed, her hands balled into fists and stomping her feet. But Applejack could tell from the way she went beet red and her eyes went shifty that she was lying. The Apple family had never been any good at lying and Applebloom was no exception.

Scootaloo too was visibly sweating whilst Rainbow’s grin grew wider, she placed a hand on Scootaloo’s shoulder and knelt down so her eyes were level with Scootaloo. “You were weren’t you?”

"We weren't perving," Scootaloo squealed indignantly, but Scootaloo was a little more nervous.

"We were spying though," Applebloom admitted, her eyes shifting to the floor. "But we had a good reason."

Applejack considered scolding Applebloom and trying to frame her as the guilty party here but instead, making her easier to manipulate, she opted to find out more. “And what possible reason could you have for spying in the first place?”

The two looked at each other, their faces squirming in guilt. There was an unspoken secret between the two sisters, and Applejack had a suspicion as to what that secret was. But the two girls didn't seem to be willing to speak up just yet. "We were worried about Sweetie Belle. She's been ignoring our meetings and hasn't been talking to us so we needed to find out what was going on."

"And did you?" Rainbow Dash asked, an excitedly perverted grin on her face.

"Yeah, we saw everything. It was like Rarity was blackmailing Sweetie Belle somehow, she had to do everything her sister wanted. Rarity was-was-“

“Dominating her?” Applejack said softly with a knowing grin.

Applebloom paused her mouth opening in shock, Scootaloo realised it too. The two Crusaders looked up at their respective sisters, Rainbow's perverted grin now becoming apparent to the two young Crusaders. Applejack suspected they were starting to realise that this wasn't as much of a shock to the other two ponies as it should be.

But before they were called out on it Rainbow’s perverted side interrupted them. She placed two hands on each of Scootaloo’s shoulders and stared directly into her eyes. “Tell us everything. Every detail.”

The two crusaders were clearly taken off guard by the intensity of her demand. They looked to Applejack as if expecting her to tell Rainbow to back off but were caught off guard when they found that she was giving them an encouraging gaze. The two Crusaders squirmed until it was Scootaloo who spoke up first. "We followed Rarity and Sweetie Belle since they got off the train station all the way back to the boutique... then when they were just outside the boutique Rarity said something."

"Ah can't remember what it was she said but when she said it Sweetie Belle just stopped dead in her tracks and flashed her ass at her sister,"

"Ya'll mean right there in public? Where anypony could see her?" Applejack asked, but she couldn't keep the giddiness off her face. Applebloom was naturally taken aback by Applejack’s reaction, but as the blush spread across her cheeks Applebloom didn’t think she had the right to call her sister out.

“Uh huh, she had Sweetie Belle flash her ass right there in public,” Applebloom said, as she thought about it she could feel her heart begin to pulse more rapidly as she thought about that pale soft ass she saw.

“Was it hot?” Rainbow blurted out before being elbowed by Applejack. Neither Crusader knew that Rainbow could be this perverted, and Applebloom was glad that she didn’t have to answer.

Scootaloo was the next to speak. “After that, we followed them into the boutique and heard moaning upstairs.”

“Describe what you two girls saw. In explicit detail Sugar,” Applejack said, her hands squeezing her younger shoulders, a hint of desperation in her voice which unnerved her younger sister. Yet Applebloom went into detail explaining what she saw in Rarity's room.

"And after you saw Rarity order Sweetie Belle to eat out her delicious cunt did you leave Sugarcube?" Applejack asked her sister. The red-haired farmgirl stumbled back, her face pale with fear yet also tinged with a red blush as Scootaloo did the same. Her sisters couldn't know. Could they?

"Err no... we didn't..." Scootaloo admitted, twiddling her fingers as her eyes darted to the floor in shame. Rainbow's grin became ever wider as she imagined what had happened.

"You watched, didn't you? Both of you?" She said with a spark of perverse delight in her eyes. The two crusaders nodded in shame but they could both feel their blood simmering with lust as they thought back to it.

“Ah know that look, watching Sweetie Belle licking Rarity's perfect cunt got both of ya'll quite hot and bothered didn't it. Ah bet you liked looking," Applejack added, her grin becoming perverse in a way that Applebloom didn't believe was possible for her sister.

"Ah didn't perv!" Applebloom protested, but Applejack had that infuriating look on her face. The one she always had when she had caught Applebloom in a lie.

"Ya'll know better than to lie to your big sis Sugarcube," she said with that infuriating patience that made Applebloom crack.

With her face beet red and her hands clenched into fists she growled out, "yeah."

"And you too Scootaloo?"

"Maybe."

"And was perving all you two girls did?" Applejack asked, it was like she knew. Both crusaders shook their heads, and at this, Rainbow laughed. It was a good-natured laugh that was shared between close sisters, almost innocent in nature.

"Alright I think I know what you two girls need, follow me."

"But what about Sweetie Belle?"

"We'll deal with all that soon but for now let's see what Rainbow Dash has in mind," Applejack said, hushing her sister forward. She had a suspicion as to what Rainbow was doing, and she wanted to join in.

A/N: So good news on the vote. I've got a much clearer idea of what the Canterlot and Cloudsdale arc will involve, so if that somehow gets the first place (unlikely but I don't intend to close the poll anytime soon) then we'll have a much clearer idea. For now though Foreign Kingdoms and Equestria Girls are neck in neck for first.
