After the wedding and getting the Dazzlings getting enrolled back into CHS, everything was going pretty good for the girls.

Rarity hummed happily as she skipped a lingerie shop with a bag in her hand.

"Ooh, I can't wait to show the girls my newest underwear, with my new wife~." Rarity purred as she spanked her butt softly.

As Rarity walked she saw the cellist player, Octavia, walking to a music shop.

"Octavia, what is she doing here?" Rarity wondered, then she noticed Octavia had a mischievous look on her face.

Rarity hid behind an alley so she wouldn't be spotted.

"Is she going to do what I think she's gonna do?" The fashionista asked herself, "Pfft, of course not, she couldn't possibly in the million years ever-"

Rarity was cut off when she heard screaming as she peered over to see the cellist with her skirt hiked up, and her booty pressed up against the glass.

"Oh my goodness…" she whispered.

Octavia laughed a haughty laugh while she rubbed her rear up and down the window, as well as side to side. Each time it moved it made a squeaky noise and the flesh rippled and kneaded like two giant balls of playdough.

"That's right people, get a good look at these bongos!" Octavia remarked, rubbing her ass further onto the glass.

"Oh my Goodness… what a large butt that girl has…!" The shocked patron remarked.

However, Octavia on the other hand, could care less what they were saying about her. She even wiggled her butt, creating louder squeaky noises. The cold touch of the glass made her shiver, but she was having too much fun to notice.

"Ooh! This is so naughty! And so much fun!" Octavia expressed, giddy.

Octavia continued to squish her buttocks against the windows harder and harder, so much in fact that even her pussy had come into view for the store patrons to see. The cellist giggled with excitement and the chills she was getting from the cold glass and the thrill of mooning a group of folks that she hated had started to make her wet, drops of their juices began to slide down the window, not that they noticed.

Meanwhile inside the shop, the cashier lady was getting angrier, as evident by her red face. She picked up a phone from the counter and began dialing a number. "That's it! I'm calling the police!"

Octavia looked back, saw that the cashier was dialing a number and took that as her cue to leave. She quickly dropped her skirt with a yelp, pulled up her undies and dashed away as fast as she could.

The one thing she left behind was an imprint of two massive round cheek marks on the window and some pussy juice too.

Eventually, Rarity came out of hiding after the police left and went to where Octavia was, still surprised that her of all people, mooned a music store.

"I can't believe what I just witnessed." Rarity spoke with some shock, "Octavia, the cellist and member of the jazz club, actually mooned a shop full of people."

Rarity then looked over to see the butt imprint she left as well as the pussy juice too. Rarity gasped a little when she saw how large the print was, it was slightly bigger as her butt imprint and she should know.

"My word, that girl has a larger derriere than me." Rarity remarked looking at the imprint as she then went and touched the leftover pussy juice left by Octavia and tasted some of it. "Mmm and judging from this stain, she was really excited."

Rarity ran for a good couple minutes until she was out of that area of town. She panted and took a brief moment to collect herself, before continuing to walk back towards her house, acting like nothing out of the ordinary happened, though she did still sway her hips a bit.

Just as she was about to enter inside her house, her ears picked up the faint sound of sirens, causing her to grin to herself yet also panic a little on the inside, the same feeling she felt the first time she mooned that clothing store.

She quickly got inside before anyone saw her and closed the door shut before locking it behind her.

Rarity soon reached her room, opened the door and after stepping inside and approaching her bed she fell onto it face first and sighed.

She let her body sink into her bed while recollecting the events that just transpired. "I witnessed Octavia, the refined cellist and member of the Jazz club, bare her derriere." She thought in her head.

"But why in the world would she do such a thing?" Rarity asked herself but shrugged it off and said, "Oh whatever, I'll worry about it tomorrow right now I just wanna have some time with my new wife~."

Rarity giggled as she looked at the new lingerie she bought.

---

The next day, after having some fun with her "wife", Rarity goes to the band room after class is over. Inside, she saw the glass part of the door covered up and all her bottomless friends chatting and eating snacks.

Some time after the wedding, the girls all decided to form a club all about butts, a club where they could walk around with their asses hanging out with no fear of judgment. The girls came up with a cover story for the club, saying it was an "Anatomy club." One for people to learn about body parts. It took a bit of convincing, and Pinkie offered her cake, but they managed to get Principal Celestia to approve of the club and be their adviser.

"Hello girls, booty-ful day we're all having aren't we?" Rarity asked in a joking tone, taking her bottom clothes off and she put them with the rest of the clothes.

The girls all giggled at Rarity's little joke.

"Hehe, Booty-ful, nice one." Adagio commented.

"Thank you." Rarity replied as she then says, "Now onto more important matters."

"Like making imprints in clay?" Pinkie asked, pointing to the clay.

"Aside from that, you girls will not believe what I just witnessed yesterday." The fashionista said dramatically.

"What is it? Rainbow Dash not wearing panties?" The farm girl asks only to get pinched on the butt cheek making her yelp in surprise.

"That was one time!" The jockette exclaimed as she grabbed a bottle of water and started drinking it.

"No, I witnessed Octavia Melody giving a music shop 'pressed ham'!" Rarity exclaimed which made Rainbow Dash spit take and the girls gasp in shock.

"What?!" Sunset asked in shock.

"No way!"

"That can't be true, right?"

"It can't be, Octavia is lady-like, like Rarity is sometimes."

“Not anymore! She’s just like us as it turns out!”

“Ooh! Are we gonna invite her to join our butt club?” Pinkie inquired, curiously and excitedly.

“I don’t know, we just might.” Rarity grinned.

"Now hang on, girls, how do we know for sure Octavia wants to join?" Sunset asked, being the voice of reason here.

"Yeah, for all we know that could have been a one time thing." Applejack agreed.

"Hm, I suppose you may have a point." Rarity admitted .

"So, um, should we ask her if Octavia wants to join? And why did she mooned those people? And… if she’d like to do it again…?" Fluttershy inquired.

"Yeah, we should, we don't wanna rush her." Adagio replied.

"Good call." The techie replied.

“By the way, Rarity, you happen to see the school paper lately?” Applejack inquired curiously.

“Oh, you bet your freckled bottom I have!” Rarity winked.

“School paper? What school paper?” Sonata asked, confused.

"The one you're sitting on, Sonata." Aria groaned.

Sonata looked down at the paper she’s sitting on and pulled it out from under her bare bum. On the front cover, is Rarity’s underwater butt photo, the same one the Dazzling’s posted, only censored.

“Ooh!” Sonata commented with interest.

“Yeah, everyone’s talking about it. They’re all wondering who’s butt it is and how big it is.” Sunset said. “Wallflower’s even gonna put it in the school yearbook as the anonymous butt."

“Ooh, I wish I could tell them that it’s mine! But as such, I have to remain anonymous, and possibly wear different colored panties."

"Yeah, I wouldn't want to ruin your infamy with purple panties." Aria smirked.

"I still can't believe Celestia is okay with us being… like this." Fluttershy confessed.

“Yeah, guess our principal’s just as big a perv as we are.” Rainbow remarked.

“Question is… is Octavia also?” Rarity wondered.

"Guess the only way to find out is to ask her." Sci-Twi replied, with the others nodding in agreement.

---

Sometime later, Octavia was leaving the jazz club, locking the door behind her. She turned around and saw Rarity standing in front of her.

"Ah!" Octavia yelped before calming down. "Oh Rarity, what a nice surprise."

"Hello Tavi, may I ask you something?" The fashionista asked.

"Yes? What is it?” Octavia inquired.

"Well, you see… the other day…” Rarity began.

“What about the other day?” Octavia inquired.

“Well… let me put it this way; how did that glass feel on your ass?” Rarity whispered with a cheeky grin.

“Why would you ask…" Octavia asked before she gasped upon realizing what Rarity was talking about. She quickly started whispering quietly "Ohh… no! You saw, didn't you!?"

“By chance, yes.” Rarity confirmed.

"Please, please do not tell anyone about my… scandalous act!" Octavia whispered

"Don't worry I won't tell, but I must ask, why in the world would you do such an act?" Rarity inquired.

"Well I'll tell you, but can we be somewhere… private?" The cellist asked.

"Of course, we can go to my place, my folks and Sweetie Belle will be out for the night."

"Splendid." Octavia replied.

---

Later that night, Octavia arrived at Rarity's place as she knocked on the door and it was opened and she was met by the sight of half naked Rarity, making her blush.

"Octavia! So glad you could make it.” Rarity smiled, oblivious to the cellist’s uncomfortableness.

"Oh uh, oh my… I didn't realize you were in the middle of changing, apologies." Octavia said, blushing at the site of the half naked fashionista.

"Oh it's quite alright, come in, don't wanna catch something do you?" Rarity asked as she and Octavia went inside the house.

"I suppose not, no." Octavia replied.

Sometime later, the two girls were sitting in the living room drinking lemonade with little umbrellas in them.

"So Tavi, I have to ask, what gave you the motivation to bare your derriere to that musician shop?" Rarity asked while playing with her umbrella.

"Well, if you must know, I was getting back at them for disrespecting my skills as the cellist, they had the nerve to call me a hazbin and compare me to the musicians at Crystal Prep, saying they play better Jazz than me, I have been playing jazz since I was an toddler!" Octavia exclaimed, as composed herself and continued, "So Vinyl told me the only way to get back at them was to… bare my derriere at them. At first I was shocked and repulsed by such a crude act, but once I witnessed some videos, I became enticed and wanted to try it myself, and it was amazing!"

"It did?" Rarity inquired, surprised Octavia, the girl who is just as refined as her, enjoys mooning.

"Yes, and as for the feeling, it was cold at first but also sort of arousing at the same time." Octavia confessed

"I bet it did, I felt that same feeling too when I first mooned that clothing store I disliked." Rarity admitted.

"You too?" Octavia inquired, surprised she wasn't the only mooner.

"Yes, at first I too was disgusted when I first saw Rainbow Dash bare her derriere at that bus of crystal prep students, but it peaked my curiosity and eventually I became hooked on butt related things." Rarity explained.

"Oh my, and here I thought I was the only one." Octavia remarked.

"Well not to worry Tavi, you're not the only one who's into mooning." Rarity replied.

"What do you mean?" The cellist inquired.

Rarity explained how she and the girls, along with the Dazzlings and Celestia, made a club for girls with big butts who like to moon people, among other fetishes.

At first Octavia was surprised by the fact the principal would approve of this but listened to what Rarity was saying.

"Oh my, I didn't know there was such a club." Octavia remarked.

"Yes it lets girls and women explore those fetishes and get, shall we say, down and dirty~." Rarity purred as she spread her legs flashing Octavia her wet pussy making her blush red unable to look away from the fashionista. "Mmm and it feels so amazing darling~."

"Why Rarity, if I didn't know any better, I'd say you're trying to get me all hot and bothered~." Octavia purred, eying the fashionista's pussy and half naked body.

"And what if I am darling? What are you going to do about it~?" Rarity replied seductively showing her wet womanhood to the cellist.

“I might have a few ideas.” Octavia smiled as she reached over a tickled Rarity’s clit.

“Ooh!” Rarity giggled and moaned. “Oh! And I should let you know, I’m a married woman. But don’t worry, I'm sure she won't mind."

Rarity extended her hand and Octavia quickly saw the diamond ring around her finger.

"You’re married? Well, this is news! And who exactly is the lucky lady?" Octavia inquired.

“Why, I’m using her to sit on this chair right now.” Rarity revealed.

"Uh, beg pardon?"

"I'm married to my booty, darling."

"Ohh! Right, that makes more se- wait you married your buttocks!?"

“Why yes, had a ceremony and everything. I’m actually thinking of giving her a name too.”

"Oh my, I've heard of people marrying their reflections and pets, but… getting hitched to their gluteus maximus. Now I've heard everything."

“Yes, I know it's quite bizarre… in fact, did you know that my rump sometimes seems to have a mind of its own?” Rarity revealed.

"Good lord! Is this because of that equestrian magic you girls keep encountering?" Octavia inquired.

"Twilight believes that is a possibility. Do you wish to see?” Rarity offered

"Hm, of course, consider my curiosity peaked.” Octavia said.

Rarity then got up, and turned around and showed the cellist her booty as it vibrated on its own.

"Oh my, your arse jiggled yet you didn't move your hips." Octavia remarked while admiring how the fashionista booty vibrated without her hips moving. "And quite the eye looker too."

"Oh why thank you darling." Rarity replied as her butt vibrated a bit, making Rarity giggle. "And my wife says ‘thank you’ too."

"You're welcome." Octavia replied before she got a naughty idea. "Well I've already seen your moon Rarity…"

The cellist turned around and held the waistband around her skirt, as Rarity turned around too as she heard Octavia say, "But, it's only fair if you see… my moon!" Octavia exclaimed as she whisked her skirt and panties down showing Rarity her light gray arse.

“Ooh, you do have a sizable posterior!” Rarity commented with a smile.

“Why thank you. I am working with 35 inches after all." Octavia replied as she then moved her hips up and down to make her ass shake.

“Ah, just like me! So nice to know.” Rarity smiled as she bumped butts with Octavia, who butt bumped her back. The two soon started rubbing their asses together, the flesh of their asses moved, kneaded and squished together continuously.

The two girls giggled and cooed as they felt their asses rubbing together feeling their warm embrace.

"Rarity if it's not too much trouble may I… partake in your peach~?" Octavia asked, seeing Rarity's wet pussy.

Rarity smirked lustfully as she then got down on all fours and shook her ass as she said, "Of course my dear, partake in nectar~."

"Why thank you~." Octavia replied, as she hesitantly asked, "Can I… touch your butt?"

Rarity giggled. “Sure. Go ahead.”

Slowly but surely, Octavia moved her hands closer and closer until she finally placed both of her palms on the fashionista's rump. Both her hands seemed to sink a little into the flesh of Rarity’s derriere like dough.

"Oh my, looks like eating that ice cream really did wonders for your bottom, and possibly cake too." Octavia said in awe while cupping and making both cheeks move. “Goodness, this bounce…”

Rarity moaned with pleasure as the cellist continued to knead her hiney like balls of clay, even rub one of her butt cheeks with her face cheek.

“ Mmm~, your butt is really sensitive, isn’t it?” The cellist commented. Octavia then notices Rarity's pussy dripping and says,“Hey… something dripped down.”

"Ohh my, it must be my peach's honey~." Rarity purred.

"Do peaches even have honey?" Octavia inquired.

"Why don’t you lick it and find out?” Rarity offered coyly.

Octavia extended her tongue, and leaned towards her sister’s pussy. Her tongue made contact with her soft skin. The same warm flesh she had felt on her fingers earlier. She licked it, leaving a trail of saliva behind on Rarity’s smaller peach.

"Mmm~ how's the nectar~?" Rarity moaned and smiled.

Octavia licked her lips. “Sweet… salty too… and… a really sweaty”

Rarity giggled and shook her ass a bit more, enticing Octavia more, "Well, there's plenty more where that came from~." Rarity smirked. “Besides, you ran your tongue up my slit. You have to go all the way now.”

"Fair enough." Octavia agreed.

With Rarity down on all fours Octavia kneeled down behind her, eying the fashionista's booty.

The cellist placed her hands on Rarity's ass cheeks, in order to get a better grip of her booty. She kneaded her ass in her hands, getting a feel of her springy butt flesh. Her fingers once again sank into her ass, spreading open her cheeks and getting a look at her puckering anus. It was a bright pink anus, to match the fresh pink insides of her pussy

"Ooh… Octavia…” Rarity moaned.

"Hmm, which hole should I start with first?" Octavia mused. “Hmm… I still got that taste on my lips… and I want more.”

Octavia moved her fingers down to Rarity’s pussy, spreading it open, looking at her wet, pink folds before letting it close. She stuck her tongue back inside and started slurping and licking loudly.

This made Rarity moan loudly, her entire body blushing bright red and sweating in response to Octavia's licks.

“Ah! Lick! Deep inside me! Lick me like your mean it!” Rarity proclaimed.

The cellist obliged and started licking every part of the fashionista's pussy, covering every part of her insides. As she teased her clit, Rarity moaned and practically screamed.

“Your breath is… so warm!” Rarity exclaimed.

Octavia continued to suck, slurp and lick Rarity's private place, with the fashionista enjoying every second of it and Octavia sticking her own hand under her dress to finger herself.

"Oooh~ mmm~ Octavia, my nectar is…" Rarity began before she finally reached her limit. As Octavia’s tongue got halfway inside of her pussy and Rarity squirted. She raised her ass in the air, spraying Octavia in the face, before she drank it all up that is.

"Mmm, yummy~ sweet, salty and sweaty~." Octavia purred.

"Haah… why… ooh… thank you… oh my, you were amazing." Rarity said, panting through the afterglow of that pleasure.

Octavia then looks at Rarity's puckering anus and says, "You've experienced round one, now for round two~." She then buried herself in Rarity's butt and proceeded to lick Rarity's butthole which made the fashionista yelp.

"Ooh! Ahh… oh my~! Octavia… wha- what are you… Ooooh~!" Rarity tried to say but moaned when she felt Octavia's wet tongue lapping her anus as the Cellist kept at it licking Rarity's puckering starfish and hearing the fashionista moaning.

"Mmm you're even wetter there in your coochie Rarity~." Octavia commented seductively as she went back to licking Rarity's butthole.

"Mmm… well it's because… ahh… I came… a mo-oh~ment ago…" Rarity said between her moans as Octavia kept licking Rarity's anus.

"And it seems that I'm doing an excellent job." Octavia remarked as she leaned my face down and slowly licked the rim of her ass.

Rarity jumped but moaned instead of pulling away, Octavia continued to tease her hole and let her tongue play with her hole, rimming her tight yet clean hole.

"Mm~ Mmm~ your arse is quite nice Rear-ity~" Octavia teased between her licks as she then tongued Rarity's starfish making the fashionista moan in pleasure.

"Your breath is... so warm!" Rarity exclaimed.

Octavia continued to continue to suck, slurp and lick the fashionista's other private place, with Rarity enjoying every second of it and Octavia sticking her own hand under her dress to finger herself.

"Oooh~ mmm~ Octavia, my nectar is..." Rarity began before she finally reached her limit. As Octavia's tongue got halfway inside of her anus and Rarity squirted. She raised her ass in the air, spraying Octavia in the face again, before she drank it all up that is.

"Haaah… ohh my… how…in the world are… you… this good?" Rarity asked, taking a breath between each sentence.

"I may have watched a video or two… and done it with Vinyl before…" Octavia confessed recalling her experiences and observations.

"Hm impressive, well how about I return the favor~." Rarity purred as she turned around, took hold of Octavia and spun her around before making her lie on her stomach.

As she spread Octavia’s legs and laid down between them, Rarity stuck her face in Octavia’s crotch and started licking all over.

“Oh! Ooh! Oh my… Ah!” Octavia cried out, her whole body shaking as Rarity coated her pussy and anus with her saliva. She gripped the floor tightly, grit her teeth and curled her toes as the pussy licking continued.

As Rarity’s tongue got deeper inside and her moans became louder, Octavia started to raise her ass into the air. Rarity gripped Octavia’s hips as it went further up and started to sit up as well.

Eventually, Rarity stood behind Octavia on all fours, her face buried in her snatch. Meanwhile, Octavia had her top half on the floor and her bottom in the air.

"Mmm, oh… That’s it dearie, keep going…!” Octavia encouraged.

Rarity then moved her face away as got on her knees, tightened her grip on Octavia’s hips, then pulled them back into her, pressing her soft butt cheeks into her own hips and crotch.

The fashionista quickly began to rub her hips and crotch against her butt.

"Mmm, oh yes! Your snatch is sooo wet Rarity~!" Octavia exclaimed.

As Octavia began to rub her butt up and down against Rarity, the purple haired girl gasped sharply as she gripped her hips, guiding them as she pressed her crotch forward against them. Rarity’s mouth fell open as Octavia got on all fours and continued to work her hips around her crotch.

Octavia then began to gyrate her hips in a circular motion.

“Oh my!” Rarity gasped. “Oh, goodness!”

Octavia grinned and began to grind her hips harder back into Rarity, who just kneeled where she was with her mouth still hanging open .

Eventually, Rarity pulled her hips back and thrust her crotch forward until it connected with Octavia’s arse with a loud SMACK.

"Oh my Goodness!" Rarity gasped again. "Yes!"

Rarity began a rhythm, and Octavia seemed to catch on, moving back and forth on her hands and knees, smacking her butt against Rarity’s crotch repeatedly. It continuous smacking sounds almost sounded like a person, or an audience, clapping.

“Oh dear… Rarity I… I believe I’m going to cum!” Octavia exclaimed.

“As… As am I!” Rarity replied.

“Shall we…?”

“Together?”

“Yes.”

“Let’s!”

And with a loud moan, both girls screamed and squirted on each other's butts at the same time, covering each other's asses in love juices. Both tilt over and land on their sides before turning over onto their backs. Both the carpet and their bodies were covered in sweat.

"Ohh haaah, my… that… was… incredible!" Octavia expressed.

"Glad… to be of… service…" Rarity replied, out of breath. “You know, I can’t believe the two of us have never done this before.”

"Neither can I, although it would have been better if we had a toy, or perhaps a long cucumber or a carrot." Octavia admitted. “Still, at no point did it feel strange in any way.”

“Indeed.” Rarity nodded.

“Does this… Does this count as cheating for you?” Octavia wondered.

“Since my derrière and I are connected, we share whatever partners we make love with, so no.” Rarity explained.

"So it's… an open marriage?" Octavia asked.

"In a… manner of speaking.” The fashionista shrugged.

"Fascinating.So, what was this club you spoke about earlier?" Octavia inquired.

"Ah, yes, the butt club.” Rarity recalled. “Interested in joining?”

“Oh, nothing would make me happier.” Octavia expressed lovingly.

The girls turned onto their sides to face each other, smile as they cup each other’s faces, and then kiss. Rarity’s butt vibrated a bit as the two French kissed, and soon enough, Octavia’s derriere started to do the same.

"Mmm~, I feel as though my own bottom wants to join as well.” Octavia purred.

"Oh, splendid." Rarity remarked.

"That being said, have you done any other butt related activities?" Octavia asked.

"Hmm, well so far we have done, mooning, twerking, oiling our bums…” Rarity began.

“Interesting…” Octavia marvelled.

“We also discuss booty politics.” Rarity added. "As well as go bottomless, and occasionally kiss, lick and eat off each other’s buns too."

"Wait, does that mean you put the food in your…"

Rarity blushed and replied, "No! No! just on top of each other's cheeks.”

Octavia sighed in relief. “Oh, fabulous…”

“You know, on top of different booty sizes, there’s also curves, angle, aspect ratio, softness, spankableness, dimples, blue spot, color, texture, shape, etc, etc.” Rarity revealed. “There’s charm in all types.”

"I see, also, what's a blue spot?" Octavia asked as she then turned around and spread her butt cheeks showing Rarity her puckering anus, "Is it this?"

"Oh, no, they’re marks that appear at birth or shortly after. They appear commonly at the base of the spine, on the buttocks and back and also can appear on the shoulders.” Rarity explained. “Twilight told us about them while she was researching.”

"Oh I see, hm, well after hearing that I want to join your club." Octavia replied.

“Excellent!” Rarity beamed before kissing Octavia’s rear.

"Ooh my…" Octavia remarked.

"I am an amazing kisser. You know, just the other day when I was in the girl's wash room, I noticed there was a bum mark on the bathroom stall doors." Rarity replied

"Ohh, that might have been my doing." Octavia confessed.

"That was you? I thought for sure it was Rainbow Dash or Pinkie Pie" Rarity commented in surprise.

Octavia giggled and said, "No, it was all me and my derriere~."

Rarity smiled. “Oh, you are most definitely going to fit right in."

"Sounds delightful."
