After some time, Rarity finally arrived at Sci-Twi's house, as she opened the door and entered the house, still unaware that wasn't wearing any panties, even as she hurried up the stairs. She does stop and shiver though.

"Ooh, a little breezy." Rarity commented.

She soon arrived at Twilight's door and entered the room.

"I'm here! Sorry for not… oh my…" Rarity started as she looked to see the girls are having sex with each other.

Rainbow laid on her back and moaned as Applejack laid in-between her legs and ate her out while Adagio fingered Applejack's anus. Sunset had Sci-Twi bent over her bed while she smacked her crotch into her butt repeatedly and moaned herself as Aria licked the spot between her legs. Fluttershy and Pinkie move in unison as they scissor each other while Sonata plays with their boobs.

"Oh, hey Rarity, you're back… ahh yeah…" Rainbow moaned.

"Uhh… well I apologize for my absence so what were you all… up to?" Rarity inquired

"Oh the usual, mooning each other, twerking, ass clapping, spanking, scissoring, the usual." Pinkie listed before moaning.

"Oh so I didn't miss anything then." Rarity replied.

"Well you did miss when Pinkie Pie ate Adagio's cake." Applejack pointed out and went back to eating out Rainbow Dash.

"And by cake you mean…" Rarity started before Adagio turned around and mooned Rarity, showing her frosting covered booty. "Ooh, that cake…"

"It was super yummy, and don't worry, there was no chocolate filling." Pinkie reassured her.

"Thank goodness, that would have been a major party foul." Aria commented and shivered in disgust, "And gross."

"So Rarity, you wanna get in on this?" Adagio asked as she turned around and shook her booty at her, "There's extra frosting, and if you're lucky, some nectar~."

"Oh my…" Rarity muttered, stunned.

Pinkie looked at Rarity's skirt and noticed something.

"Uh, Rarity, where are your panties?" The party girl asked.

"Pinkie there under my…" Rarity started as she felt under her skirt and realized that she wasn't wearing any panties "Ooh bullocks! I knew I was forgetting something when I left the house!"

"You came here… with no skivvies?" Applejack remarked..

"Apparently so, yes, I must have left them at home." Rarity replied.

"Wait, did you not notice the entire time when you were getting here?" Sunset inquired.

Rarity's mind thought back to earlier…

---

Rarity was power walking to Sci-Twi's house, still unaware of the fact that she wasn't not wearing panties.

"Gotta hurry, gotta hurry!" She exclaimed and kept waking faster.

Rarity kept jogging, her butt jiggling under her skirt with each step she took. After a few more feet, Rarity stopped to take a breather.

"Ah, phew, oh my goodness." Rarity panted, "That's the fastest I've ever ran."

Rarity then looked and saw a dollar coin on the ground.

"Ooh, a dollar coin, don't mind if I do."

Just then, Crystal Prep student Sugarcoat was walking by and stopped when she saw Rarity.

"Oh, hello, Rarity, I see you are having a hectic…gah!" Sugarcoat started before Rarity bent over. Just then, a breeze came by and blew Rarity's skirt up, showing the blunt honest counterpart of Applejack her bare butt cheeks to which she could only stare in awe.

"Must be my lucky day." Rarity spoke after picking up the coin, then noticed Sugarcoat. "Oh hello Sugarcoat."

"Uh… hi… Rarity…" Sugarcoat muttered in awe after seeing Rarity's butt.

"Darling? Are you alright? You look as if you've seen a ghost." Rarity

"Uh… I… I'm fine… isn't there some place you need to be?" The blunt girl inquired, and Rarity gasped in realization.

"Oh right! Thank you for the reminder!" Rarity replied and ran off leaving Sugarcoat alone.

"I'm definitely not telling her about what I saw… but it was pretty hot." Sugarcoat muttered and walked off.

Rarity's mind eventually returned to the present and went back to focusing on her friends.

"Hm, I suppose since I was in such a hurry that I didn't even notice." Rarity realized.

"Wow, I bet a lot of girls got a good look at your ass on the way here." Adagio remarked with a smirk.

"I'll bet I did, plus it would explain why Octavia was blushing beat red." Rarity replied recalling the memory of Octavia looking at her butt.

"Yeah, but it's no big deal! You managed to give a treat! Now let's get back to our sex party!" Pinkie exclaimed before she resumed grinding her pussy against Fluttershy's, making the both of them moan.

Rarity smiled. "Yes, let's," she declared before beginning to strip. "Oh, and by the way, I've decided that, since I can't decide between any of my friends, Sweetie Belle is going to be my Butt of Honor."

"Sweetie Belle?" Sci-Twi echoed.

"Yes." Rarity confirmed casually while dropping her skirt. "Oh, Dazzlings, I hope you don't mind but I've decided to make the rest of the Canterlot Movie Club the flower girls. Oh! Better yet, you can all be flower girls together!"

"Really? Wow. How did you convince her to do it?" Rainbow Dash asked while casually being fingered by Applejack.

"Well, we had a chat and one thing led to another…" Rarity started before the girls realized what Rarity meant.

"You didn't." Sunset remarked, eyes wide. Rarity nodded with a blush.

"I did and it was amazing. She's quite the pro." Rarity admitted.

"Wow, doing it with your little sister… respect." Aria replied, giving the fashionista a high five.

"So how good is she?" Sonata inquired, curious about Rarity's time with Sweetie Belle.

"Very good, she had me squirting like a fountain and the way her tongue licked my twat Oooh~ just thinking about it gets me hot and bothered~." Rarity replied and shuddered in arousement thinking about that memory.

"Still… that was your sister." Sunset empathized.

"Yes, I'm aware." Rarity said, casually.

"So… you don't think that crosses some kind of line?" Pinkie wondered.

"You bet it does! Foolin' around with your kin like that is…" Applejack started to rant before blushing. She quickly shook her head and went back to furrowing her brows. "It just ain't right!"

"Neither is what we're doing." Rainbow pointed out.

"Compared to somethin' like incest, it is." Applejack stated.

"Well, we did a lot of things more worse than this, so incest is just one of the few." Adagio explained.

"So did we." Rainbow Dash replied recalling all the butt related things she and the girls did.

"I guess it ain't so bad doing it with your sister when you say it out loud." Applejack admitted.

"So… is it okay to do it with our sisters?" Pinkie asked.

"I don't know… I mean doesn't Maud still have a boyfriend?" Applejack inquired.

"Mud Briar? Yep! She's straight as an arrow! An arrowhead rock to be exact." Pinkie smiled. "Limestone and Marble are too!"

"Hmm, what about your principal?" Adagio asks, casually rubbing her pussy.

"Why do you ask?" Rainbow inquired

"Well when me, Sonata and Aria were in CHS, she did glance at our butts." Adagio confessed.

"You don't think Celestia could be…" Fluttershy started, and the girls thought about it.

"Maybe?" Rainbow guessed.

"Yeah, I mean, does have a boyfriend?" Applejack inquired.

"Now girls we can't judge our principal's relationship life without knowing about it." Sci-Twi lightly scolded.

"But we can judge her butt right?" Pinkie asked as she went back to licking Fluttershy's butt.

"Oh absolutely yes." Rarity agreed.

"Okay, Principal Celestia does have ample hindquarters." Sci-Twi admitted.

"No doubt from eating so much cake." Aria quipped with a smirk, making her Dazzling sisters snicker.

"And Vice Principal Luna's not too shabby in the rear department either!" Sonata pointed out.

"And she doesn't have a boyfriend either. Could it be that since neither of them have boyfriends, and they're both very close…" Adagio began to wonder.

"What? No! No, they wouldn't be in that kind of relationship." Sci-Twi said in amusement before she started to wonder. "Would they?"

Everyone exchanged looks silently.

"I mean… they are together a lot… like… they're inseparable." Rainbow Dash spoke up, breaking the silence.

"True… but that doesn't mean they're in that kind of relationship." Sci-Twi pointed out before she wondered again. "Right?"

"Well Lyra and Bon-bon are always together so they're probably going out with each other, heck they danced together too, cheek to cheek." Applejack recalled and Pinkie Pie was able to say something until she was cut off. "And I mean face to face not the other cheeks."

"She probably has the biggest butt in Canterlot with all that cake she's eating right?" Sonata inquired.

"Well, given how much cake she eats, her butt probably… 40 inches." Sunset guessed.

"Dang, she could be bigger than Rarity and Adagio combined." Rainbow remarked thinking about how big her principal's butt could be.

"And don't forget plumpness." Sonata added.

"That too." Rarity replied as she then goes to Adagio and kisses her and then go back to fingering and scissoring each other.

Somewhere else, the CHS principal was home as she sneezed and looked around in confusion.

"Hmm, strange, it felt like someone was talking about me, oh well." Celestia shrugged as she casually took her pants off along with her panties and tossed them aside, "Ah that's better."
