Later, the girls were now in Rarity's basement, inside there was a one way mirror room, which Rarity and Trixie were inside of, while the others were seated outside it.

“Okay you two here's how it's gonna go, you two are gonna press your asses on the mirror and whoever makes a larger butt print wins.” Twilight explained

“Ooh, sounds so fun and naughty.” Trixie commented shaking her butt with anticipation

“Agreed darling, there is absolutely nothing more satisfying then pressing your rear on a window or mirror.” The fashionista replied, patting her rear, making it jiggle.

“Okay you two you know what to do.” Twilight told the girls while speaking to them over the speaker that was in the one way mirror room.

“Oh we certainly do darling.” Rarity replied back as she and Trixie shook their booties with anticipation. “The Great and Bootyful Trixie definitely knows what she's doing."

“Alright you girls ready?” Twilight asked as she saw Rarity and Trixie gave a thumbs up. “Okay you two can start…. now.”

The science girl added as Rarity and Trixie both moved backwards and pressed their butts onto the glass which made them shiver a bit due the coldness, but they quickly got used to it as they started moving their booties up and down on the glass.

Trixie giggled. "Anyone want some blue ham?” she cooed as she pressed her butt against the glass for the girls to see as Rarity pressed her large cheeks against the glass too

“Or do you rather have the white ham?” The fashionista added, playing along with Trixie as she pressed her titanic tushie on the glass too, making squeaky noises with the blue butt performer.

Meanwhile on the other side of the room, the girls were enjoying Trixie's and Rarity's butt show.

“Wowie, those are big hammies!” Pinkie remarked seeing how much Rarity's and Trixie's butts were pressed on the glass.

“You got that right Pinkie.” Rainbow agreed.

“Yeah this is some show, and the best part is we have front row seats to see these hams." Applejack added.

“Yeah this is pretty good.” Sunset nodded as she and the others stared at the fashionista and performer's butts on the observatory window.

Rarity and Trixie both peeked behind themselves and found the girls staring intently, making their naughty smirk grow.

“My, my, it looks like the girls are enjoying the show." Rarity commented seeing the girls stare at her butt and Trixie's butt too.

“Yes, it seems they're enjoying our full moons.” Trixie grinned.

“Agreed darling, let's give them a show they'll never forget.” Rarity declared.

The two bottomless girls then backed up more, squishing their fat butt cheeks even more against the glass, wiggling it while they did so and causing loud squeaking noises in the process. Memories of moaning that one store suddenly flooded back into the fashionista's mind, making her laugh a haughty laugh but she wasn't the only one.

Trixie giggled as she recalled the time she once mooned a magic store for not having the equipment that she wanted. The girls were enjoying their butt show which also made them aroused at the same time.

“Wow, this is just like when me and Rarity rubbed our butts on the window.” Twilight commented, recalling her time with Rarity at the lab.

“You two did that?" Sunset asked, surprised.

“Yep, Rarity helped me discover a side I never knew I had." The science girl admitted..

“Wow I didn't think you had it in you, Twilight." Rainbow commented.

“Neither did I, but Rarity helped me and pressing my derriere against the cold glass felt so good and pressing my butt against her butt too.” Twilight replied thinking about the time she mooned the protesters and cooling her butt on the window with her time with Rarity.

“I bet it did.” Applejack remarked seeing Rarity and Trixie's pressed hams.

The duo continued to squish their buttocks against the windows harder and harder, so much in fact that even their pussies had come into view for the girls to see as they saw how much they were enjoying it.

“Wow they are really getting into it.” Sunset commented.

“I’ll say.” Rainbow nodded, watching as the glass started to get stained with juices being leaked from the two of them.

“Oh… I never thought I’d say this, but I think I love my bottom.” Rarity expressed. “If I could marry it, I would!”

The purple haired girl’s eyes widened just then, which Trixie noticed.

“What?” she asked.

“I-dee-a!” Rarity sang with a grin.

Trixie’s eyes widened just then as well. “Wait… are you thinking of…?”

“Ok girls, as nice a view as this is, I need you both to move away from the glass now.” Twilight spoke up.

Both Trixie and Rarity moaned, a little disappointed before pulling their tokus’ away from the mirror, leaving behind some very visible and wet butt prints.

“Aw! And just when it was getting good…” Trixie complained.

“Indeed, darling, I was just about to reach my climax.” Rarity added.

“Well as much as we would all like to see that, I need to measure the results.” The science girl replied.

Twilight then went to the butt prints as she got some measuring tape and measured the wet butt prints trying not to smell the arousal from both Trixie and Rarity.

“So what's the verdict?” Sunset asked

“Looks like it's another tie, again.” Twilight replied after measuring both prints.

“Seriously? That's like the three ties in a row.” The jockette complained. “Though it was fun seeing those butts."

“Yeah, it was! Almost made me wanna join in!” The party girl replied enthusiastically.

“Well darlings I think it's safe to say that both me and Trixie have amazing derrieres.” Rarity said, wiggling her bum at the girls.

“Yes, the half-naked and Bootyful Trixie agrees with Rarity, both of our butts are great and powerful.” The performer added.

“So you're both cool on who's butt is amazing?” Sunset asked.

“Yes we are, and besides, we still have our other performance to look forward to tomorrow, wouldn't you agree, Tushy Lulamoon?" The bottomless fashionista asked the performer with a butt bump to Trixie.

“Indeed we do Rear-aty.” Trixie replied with a giggle as she butt bumped Rarity back.

The next day, the girls, all of them with their skirts on, went to Rarity's house and soon entered her room.

There, the second they enter, both Rarity and Trixie drop their skirts and undies, bent over, and mooned the other girls once again. All of them cry out and cover their eyes briefly. The two mooners giggled as they stood up straight.

“Ah, that never gets old.” Trixie smiled with a hair flick.

“No. Indeed it doesn’t.” Rarity agreed.

“So hey, what was this special performance you wanted us to watch so badly anyway?” Rainbow asked.

“Other than mooning us again.” Sunset added

“To put it plainly ladies, we’re having a wedding!” Rarity announced.

“A wedding?!” Everyone repeated in surprise.

Pinkie squealed with joy. “How exciting!” she exclaimed. “Ok, who’s getting married? Is it you? Is it Trixie? Are you getting married to each other? Can I be the Maid of Honor?”

“Ugh, somebody please make her stop…” Trixie groaned, rubbing her temples.

Sunset quickly covers Pinkie’s mouth, though Pinkie continued talking in spite of that. All of Pinkie’s words are muffled by Sunset’s palm though.

“Proceed,” she told them.

“Thank you, darling.” Rarity said appreciatively. “Any who… the person getting married is me, and the one I’m marrying is…”

Rarity smacked her own rear, which made a nice sound in the process, and smirked at the girls.

It took a second before the girls finally understood, causing them to gasp sharply.

“What?!” They all practically yelled.

Trixie winced. “Do you all mind? There’s no need to yell in unison, you know!”

“Sorry but are you seriously telling us that yer plannin’ on gettin’ married to yer bum?!” Applejack questioned, incredulously.

“That’s right.” Rarity confirmed rather proudly.

“Uh, can you do that?” Sunset inquired, baffled.

“Well, obviously it won’t be legal. As I said yesterday, it is merely a performance, one that also fulfills a personal wish of mine.” Rarity explained as she rubbed her tushie affectionately. “This derrière has opened a whole new world for me, it’s a part of me, in more ways then one. I figure, why shouldn’t I marry it? Then me and my bottom can also be joined in the bonds of holy matrimony! For fun at least!”

Everyone exchanged looks with each other.

“Uh… that sounds…” Rainbow began to say before Pinkie removed Sunset’s hand from her mouth.

“So cool!” Pinkie exclaimed with a smile. “Will you please let me arrange your wedding? Pleeeeeease?”

Rarity nodded. “It would be me and my butt’s honor, Pinkie Pie,” she said. “I was actually planning on asking you to do just that. As for the rest of you, I was hoping you all would attend.”

“Well, of course we will! Ooh! There’s so much to do!” Pinkie squealed again. “There’s the cake, the decorations, the minister… Ooh! Who’s gonna be the minister?”

Trixie put a hand on herself, smiling proudly. “Trixie, of course!”

“Great! I’ll bake the cake!” Pinkie said before she zipped off.

Rarity turned to the others. “And you girls? I know all of this is… unconventional…”

“That’s an understatement.” Applejack remarked.

“But it would mean a great deal to me if you all intended. I do not know what the future holds, and for all I know, this could be the only wedding I ever have.” Rarity expressed. “Sure, it won’t be to a man, but look at this way. If a dog like Spike can find love with a robot dog that Twilight built, why can’t I find love with my own bottom?”

“She’s got a point.” Fluttershy admitted.

Twilight adjusted her glasses. “Well… I don’t really see a reason why not if it’s all in good fun,” she confessed.

Pinkie, with her face covered in cake batter, poked her head inside. “Yeah! And who doesn’t like things that are fun? Especially if they’re booty related?” she inquired, raising her eyebrows suggestively before ducking out.

“Hmm, well… nothing else to do.” Rainbow shrugged.

“It does sound like fun…” Sunset admitted, glancing at her own butt before smiling. “What the hell? Let’s do it.”

“I still think it’s strange…” Applejack said honestly. She still sported a frown on her face, but it soon vanished when she saw how affectionately Rarity stared at and rubbed her heinie. “But if this really is what makes you happy, then I ain’t gonna stand in your way.”

Rarity was beaming with joy. “Oh, thank you, girls!” she expressed sincerely before showing them her bum. “And my butt thanks you all as well.”

Everyone blushed a little as Rarity purposely made the extra fat on her tush jiggle and shake while Rainbow Dash chuckled to herself. “What have I created?” she remarked.
