The elevator doors slid open, revealing a well-lit corridor adorned with plush carpeting and tasteful wall art. Nozomi stepped out, her eyes scanning the numbers on the doors until she found the one she was looking for. She took a deep breath, steeling herself for the conversation ahead, and knocked firmly on Sayaka's apartment door.

After a moment, the door swung open, revealing Sayaka standing on the other side. Her white hair was damp from a recent shower, and she wore a simple, comfortable-looking robe. She raised an eyebrow at Nozomi. "You're here early. I thought we were meeting at the training facility."

Nozomi shrugged, grinning. "I was in the neighborhood. Plus, I figured we could use some privacy for this... conversation."

Sayaka stepped aside, allowing Nozomi to enter. "True enough. Come on in."

Nozomi's eyes widened as she stepped into Sayaka's apartment. "Wow, Miyata. This place is... something else."

Sayaka chuckled, closing the door behind them. "Yeah, I like to keep things cozy. Make yourself comfortable," she said, gesturing to the plush couch in the living room. "Can I get you something to drink?"

Nozomi flopped down onto the couch, her eyes still taking in the eclectic mix of modern and traditional decor. "Sure, whatever you've got is fine. Thanks."

Sayaka disappeared into the kitchen, returning a moment later with two glasses of iced tea. She handed one to Nozomi and sat down in an armchair facing her. "So, I guess we should talk about..."

"Our butts." Nozomi finished.

"Yes." Sayaka confirmed.

"Are you talking about us?"Natsume AKA Nozomi's rear, chimed in, causing Nozomi's backside to light up with each utterance.

Startled, both girls stood up and cried out in alarm.

"Natsume, please don't speak so suddenly." Sayaka's butt, which called itself Yuzu, cautioned. Like Nozomi's, Sayaka's butt glowed every time Yuzu spoke.

For a moment, the two friends stared at their respective butts, their eyes wide with disbelief. Then, they turned to each other, their expressions a mix of confusion and shock.

"What the hell is going on, Miyata?" Nozomi asked."Our butts... they're talking. And glowing!"

Sayaka shook her head, her white hair swaying gently. "I don't understand any of this."

Natsume, Nozomi's butt, spoke up again. "Hey, we're not just butts, you know. We have names." Natsume's voice was filled with a playful indignation, her glow intensifying slightly.

"Y-Yeah, she's right. I'm Yuzu, and the one attached to Nozomi is Natsume," Sayaka's butt added.

Sayaka and Nozomi exchanged a glance, both still struggling to wrap their heads around the situation. "Okay, Natsume and Yuzu," Nozomi began, her voice measured. "What exactly are you?"

"We told you before, didn't we?" Natsume reminded them. "Back at the pool."

"We are entities residing within your butts, each possessing our own distinct awareness, perceptions, and experiences. Our existence is intertwined with yours, yet we maintain our individuality, shaped by our unique thoughts, emotions, and perspectives. While we share the same physical vessel, our consciousness operates on different frequencies." Yuzu explained.

"Huh?" Both Nozomi and her butt responded.

"Basically, our butts suddenly have their own minds, wills and souls." Sayaka stated. "But how does this happen? And why us?"

Natsume chuckled, "Well, Miyata, it seems both of our butts have always been sentient, but we've only recently gained the ability to communicate with you. As for why us, who knows? Maybe it's just our luck."

Yuzu added, "Or maybe it's because we're both extraordinary Keijo players. Perhaps this is some sort of divine intervention to make us even stronger."

Nozomi scoffed, "Divine intervention? More like some weird cosmic joke."

Sayaka sighed, rubbing her temples. "This is all so strange."

Nozomi nodded, her eyes still wide with disbelief. "Tell me about it. I just want to wake up from this weird dream."

"Sorry to disappoint, but this isn't a dream. We're as real as you are." Yuzu, Sayaka's butt, added, "And we're not going anywhere. So, you might as well get used to us."

Nozomi sighed, slumping back onto the couch. "Fine. But this is all so... weird."

"Welcome to the wonderful world of sentient butts, Nozomi." Natsume declared. "And do you think you can lay on your stomach? It's hard for us to speak when you're sitting on something."

Nozomi rolled her eyes and laid down across the couch on top of her belly.

Sayaka raised an eyebrow. "So, what now?"

"Well," Yuzu began, "we've been thinking. Since we're sentient and all, we figured we should make the most of it."

"Meaning?" Nozomi asked, her voice muffled by the couch cushion.

Natsume took over, her enthusiasm bubbling over. "We want to have a butt wedding!"

"A what now?" Sayaka asked, her eyes widening.

"A butt wedding!" Natsume repeated, her glow pulsing with excitement. "You know, like a regular wedding, but for butts!"

Nozomi propped herself up on her elbows, her brow furrowed. "A buttwedding?" she repeated incredulously. "You can't be serious."

"Oh, but we are!" Natsume insisted, her glow pulsating with excitement. "We've already planned everything. The venue, the decorations..."

"When did you...?" Sayaka began to ask.

"But how did you manage to plan all of this without us knowing?

"Well, remember when you both started experiencing those strange tingling sensations in your butts during the race?" Yuzu replied. "That was us, trying to communicate."

Nozomi and Sayaka exchanged a puzzled look. Now that they thought about it, they had indeed felt some unusual sensations in their rear ends lately.

"Yeah, and while you were both freaking out after learning about us, we used that time to plan our wedding," Natsume added.

"So like... are you two... in loveor something?" Nozomi questioned in disbelief. "But... butts can't fall in love. That's ridiculous!"

"Says who?" Natsume retorted, her glow pulsing with defiance. "Just because we're butts doesn't mean we can't have feelings. We may not have hearts, but we've got souls, and that's enough for us to love."

Yuzu chimed in, her voice gentler. "We understand that this might be difficult for you to grasp, but we've developed feelings for each other.

It's not just about being physically attracted to one another; it's about the connection we share, the understanding, and the bond that's formed between us," she explained, her voice soft and reassuring.

Nozomi and Sayaka exchanged a glance, still trying to wrap their heads around the absurdity of the situation.

"And you want us to..." Sayaka trailed off, hesitant to finish the sentence.

"Be there, of course!" Yuzu exclaimed. "We want you both to be a part of our special day."

"Not that you have much of a choice, considering you're attached to us." Natsume pointed out.

"And besides, think of all the fun we'll have! It'll be a chance for us to celebrate our newfound consciousness and the amazing bond we share."

Nozomi sighed, her face still pressed against the couch cushion. "I don't know, guys. This all just seems so..."

Sayaka nodded in agreement. "I mean, I'm not sure I'm ready to embrace the idea of my butt having feelings, let alone planning a wedding for it."

Yuzu's voice softened. "We understand that this is a lot to take in, Miyata.

"But we really want you to be a part of this. It's not just about us; it's about the four of us," Natsume added.

Sayaka looked at Nozomi, who seemed to be considering the idea. "What do you think, Nozomi? Should we... support them in this?"

Nozomi sighed, rolling onto her back and staring up at the ceiling. "I mean, it's weird. Really, really weird. But...

I guess if this is what makes them happy, and it doesn't hurt anyone, why not?" Nozomi finally said, a small smile playing on her lips.

Sayaka let out a sigh of relief, her shoulders relaxing. "Thank goodness. I really didn't want to be the only one supporting their little... event."

Natsume and Yuzu's glows intensified, pulsing with joy. "Thank you, thank you!" they exclaimed in unison. "You won't regret this!"

Nozomi chuckled, sitting up and looking at her friend. "Alright, Miyata. You're in charge of the decorations," Nozomi declared, her eyes sparkling with mischief. "So, what did ya butts have in mind?"

"Something elegant, yet... unique." Yuzu answered.

"Unique, huh? I think I can handle that." Sayaka said.

"Great! And I'll take care of the food," Nozomi continued, her enthusiasm growing. "Natsume, Yuzu, any dietary restrictions I should know about?"

Their butts glowed with amusement. "None that we know of," Yuzu replied. "We're open to trying anything."

"Excellent." Nozomi grinned. "I can't wait to surprise you both with my culinary masterpieces. And who knows, maybe I'll even invent a new dish inspired by your special day."

Natsume's glow pulsed with excitement. "Ooh, we can't wait to see what you come up with! But remember, no spicy food. We don't want any unwanted... 'heat' during the ceremony."

A sweat drop rolled down the back of Nozomi's head. "Uh, yeah, sure, whatever, I'll keep it mild. Now, what about music? We can't have a butt wedding without some tunes, right?" Nozomi asked, her eyes gleaming with excitement.

"It's a great idea!" Yuzu chimed in. "We've been thinking about that too. We want something upbeat and energetic, like our matches."

Natsume added, "And maybe a couple of slow songs for the... more intimate moments."

"Intimate moments? At a butt wedding?" Sayaka remarked.

Natsume chuckled, her glow pulsing playfully. "Well, you know, we want the whole enchilada. Flowers, music, dancing... the works," she replied. "We want this to be a celebration of our existence, and that includes all the trimmings."

Sayaka tilted her head, considering the request. "I think I can do that," shesaid, a thoughtful expression on her face. "Just to be clear, this ceremony will only include the four of us, right?"

"Indeed." Yuzu confirmed.

"Understood. I'll start picking some songs and researching some unique decoration ideas." Sayaka added, pulling out her phone to jot down some notes.

"And I'll try and think up foods that are good for the glutes!" Nozomi added.

Natsume and Yuzu's glows pulsed with excitement, watching their human's enthusiastically planning their special day. "Thank you both so much for doing this," Yuzu said, her voice filled with gratitude.

"No prob." Sayaka replied.

"And remember to make it all butt themed!" Natsume spoke up.

Nozomi patted her butt affectionately. "You got it," she grinned, her enthusiasm infectious, causing her and Sayaka's butt to glow brightly, reflecting their rears shared excitement.

In the days that followed, Nozomi and Sayaka threw themselves into the preparations for the unusual ceremony. Nozomi spent hours in the kitchen, experimenting with various recipes and ingredients, determined to create the perfect menu for the occasion. Sayaka, meanwhile, scoured the internet and local stores for unique decorations and accessories, her creative juices flowing as she envisioned the perfect setting for the butt wedding.

One evening, as Nozomi tasted her latest creation, a spicy tuna tartare, she let out a yelp and fanned her mouth. "Oh my god, that's hot!" she and Natsume both exclaimed. "Wait... Natsume, you felt that?"

"Duh! Whatever you feel, wefeel! We are a part of you after all." Natsume reminded her.

"So when we eat... you feel the sensation of it." Nozomi realized. "And you can taste it too! That'swhy you don't want spicy food at the wedding!Because you'd feel the heat too!"

"Exactly!" Natsume confirmed, her glow pulsing with amusement. "We may not have taste buds like you do, but we can still sense the intensity of flavors."

Sayaka, who had been quietly observing the exchange, finally spoke up. "I see. Well, rest assured, Nozomi, I'll make sure to exclude any spicy dishes from the menu," she said in a steady voice. "I wouldn't want our butts feeling any unnecessary... discomfort during the ceremony."

Nozomi chuckled, her eyes twinkling with mischief. "Yeah, I guess we should keep it PG-13, huh?"

Sayaka rolled her eyes, a small smile playing on her lips. "You're impossible, Kaminashi."

"Guilty as charged." Nozomi grinned, hopping off the couch and heading towards the kitchen. "So, what do you say we celebrate our newfound partnership with some ice cream? I've got a whole tub of mint chip back there, calling our names. We deserve a little treat after all this planning, don't you think?"

Sayaka hesitated for a moment before nodding. "Sure, why not? I could use some ice cream."

"Yay!" Nozomi exclaimed, her butt glowing with enthusiasm. "Natsume, which flavor do you want?"

"Surprise me!" Natsume replied, her glow pulsing playfully. "And maybe we can have a little dance-off too. You know, just for fun."

"A dance-off?" Sayaka repeated.

"Well... more like a twerk-off." Natsume admitted. "Again, we are butts."

"And... that's what's going to happen during the wedding too...?" Sayaka asked slowly.

"It's what you'regoing to be doing alongside us. Course we'll be making you do it whether you want to or not, but it'd make things easy if you were both more in sync with us." Natsume stated. "Think of it as a way to connect with us, to understand our joy and excitement."

"You make it sound like this is a spiritual experience." Sayaka commented.

"Isn't it?" Natsume retorted, her glow pulsing with emotion. "We're celebrating our existence, our consciousness, and our love. How much more spiritual can you get?"

Nozomi grinned, clapping her hands together. "Alright, I'm in! Let's do this!"

Sayaka sighed, shaking her head. "You're both ridiculous, you know that?"

"Maybe," Natsume replied, her glow pulsing with amusement. "But we're your ridiculous butts, and you love us anyway."

Sayaka rolled her eyes, but a small smile tugged at the corners of her mouth."Fine. We'll do a twerk-off. But only because I want to practice getting in sync with you so we don't mess up during the actual wedding."

"Yay!" Natsume exclaimed, her glow intensifying. "You won't regret this, Miyata!"

Nozomi clapped her hands together, her eyes sparkling with excitement. "Alright, let's have some ice cream then get to twerking!" Nozomi announced, pulling the tub of mint chip ice cream from the freezer. She grabbed two bowls and spoons, scooping generous servings for both of them. "Here you go, Miyata. Don't be shy, have as much as you want."

Sayaka took the bowl, a small smile playing on her lips. "Thanks, Kaminashi."

Sayaka took a spoonful of ice cream, her eyes twinkling with amusement. "So, what's the plan for this... twerk-off?"

Nozomi grinned, her mouth full of ice cream. "Well, I figure we'll just go all out, give it our best shot, you know?"

"If you say so." Sayaka sighed as she started eating alongside Nozomi.

"Mmm... I can feel the cold yet sweet sensation coursing through me..." Yuzu said, contently.

"Same here!" Natsume added. "Though it's not as sweet as you, Yuzuchi."

"Oh, Natsume..." Yuzu said, bashful yet flattered.

Nozomi snickered and whispered. "Our butts are actually flirting, this is crazy."

"What's even crazier then them being alive is the fact the they're in lovewith each other." Sayaka commented. "You don't suppose that we..."

"Might be in love too...?" Nozomi finished, sounding uncertain.

The two stared at each other awkwardly before blushing and pulling away.

"But we're not!" Nozomi quickly denied.

"Right! We're not!" Sayaka added, flustered. "We're just friends. Best friends. Rivals really."

"Sure, sure," Natsume teased, her glow pulsing with amusement. "Keep telling yourself that."

Yuzu chuckled, "We're just saying, there's no harm in exploring your feelings. After all, we're proof that even the most unexpected things can happen."

"But we're not talking about us," Sayaka insisted, her cheeks still flushed. "We're talking about you two and your... wedding."

"Right!" Nozomi chimed in, grateful for the change of subject. "So, when and where is this butt wedding happening?"

Yuzu replied, "We thought it would be nice to have on the land platform you use for keijo races. As for the date, we were thinking of next Saturday. That gives you both a week to prepare."

"Next Saturday?" Sayaka repeated, her eyebrows raising. "That's kind of soon, isn't it?"

Nozomi nodded in agreement. "Yeah, that's not a lot of time," she added.

"But I guess we can make it work, right, Miyata?"

Sayaka sighed, running a hand through her white hair. "I suppose we'll have to. Let's just hope nothing goes wrong."

"Nothing will go wrong, Miyata. This is our special day, and we want everything to be perfect," Yuzu reassured, her glow softening.

"Speaking of perfect, we were thinking you could wear something special for the occasion," Natsume added, her excitement building.

"Like what?" Nozomi asked, her eyes narrowing playfully. "Something fancy? Some revealing? Something like..."

"Your birthday suits!" Natsume declared. "After all, we are butts, and we want to see our partners in all their glory."

Nozomi's eyes widened, and she spluttered, "N-Natsume! That's... that's too much!"

Sayaka, who had been mid-sip of her ice cream, choked and coughed, her face turning beet red. "K-Kaminashi, you have to admit, that's not a bad idea," she managed to say between coughs.

Nozomi gaped at her friend, disbelieving. "Miyata, are you suggesting we go... nude for this butt wedding?"

Sayaka blushed. "Well, it is a butt wedding, after all. I mean, think about it. It would be quite something. Two world-class Keijo players, bare as the day they were born, twerking their hearts out for their sentient butts."

Nozomi's jaw dropped, and she laughed, shaking her head. "You're serious, aren't you?"

Sayaka shrugged. "It's not like we haven't seen each other naked before." Sayaka pointed out, her cheeks still flushed. "Remember all those times we had a bath with everyone?"

"Well, when you put it that way..." Nozomi hesitated, considering the idea.

It was certainly unconventional, but then again, so was the entire situation. She looked at Sayaka, who seemed to be waiting for her response.

"I don't know, Miyata. It's not like we can just... walk around naked in public. Even if it's just the two of us and our butts, it's still... out there," Nozomi said, gesturing vaguely towards the balcony and the city beyond.

Sayaka nodded understandingly. "I know what you mean. But remember, this isn't just any occasion. This is our butts' wedding. A once-in-a-lifetime event, and we should make it as special and memorable as possible," she stated, her voice softening as she glanced down at Natsume and Yuzu's glowing forms. "Besides, who else can say they've attended a butt wedding?"

Nozomi chuckled, considering the idea. "Well, when you put it that way..." she muttered before laughing. "Ok, ok, I'm sold."

"Good." Sayaka nodded.

"But there's no way we're doing this without some proper music. We need to set the mood, you know?" Nozomi reminded her.

Sayaka nodded. "Agreed. I'll make sure to bring some speakers and a playlist that'll get us all in the zone."

"And I'll make sure to bring some towels," Nozomi added, winking. "Just in case we get a little... sweaty."

"Good thinking," Sayaka replied, a small smile playing on her lips.

"So, I guess it's settled then. Next Saturday, we'll be... butt-naked, twerking our hearts out for our sentient butts."

Nozomi snickered, shaking her head. "Wow, that sounds so strange when you say it out loud."

"Tell me about it," Sayaka sighed, rubbing her temples. "But we've come this far, so I guess we might as well embrace the weirdness."

Nozomi reached out and patted Sayaka's shoulder reassuringly. "That's the spirit, Miyata. Embrace the weirdness," she said, grinning. "And speaking of weird, I think it's time we practiced syncing with our derrieres, don't you?"

Sayaka sighed as she got off her seat. "Yes," she agreed.

"Let's start practicing."

As they stood up, Nozomi and Sayaka looked at each other, a mix of nervousness and excitement in their eyes.

Once they were in the center of the living room, they turned their backs to each other and started slowly swaying their hips to the rhythm of the music playing in the background. Natsume and Yuzu's glows pulsated in time with the beat, encouraging their human counterparts to move faster, to let go of their inhibitions.

Nozomi and Sayaka's breath hitched as they felt the connection deepen, their bodies responding to the silent commands of their sentient butts.

"Faster," Natsume urged, her glow intensifying. "Let us feel your passion, your desire."

The two women picked up the pace, their hips gyrating in sync, their bodies undulating like waves and the flesh on their butts jiggling as they shook and popped them out. Their hearts pounded in their chests, their bodies slick with sweat as they danced, lost in the rhythm and the connection with their butts.

Nozomi and Sayaka's breath came in ragged gasps, their faces flushed with exertion and something more, something deeper.

"Fuck, this feels incredible," Nozomi panted, her voice heavy with desire. "I never knew... I never knew it could feel like this."

Sayaka nodded, her eyes locked with Nozomi's. "I know... it's like... it's like we're one. Like we're truly connected."

Natsume and Yuzu's glows pulsed brighter, their excitement mirroring their humans'.

Allowing themselves to let the entities inside their butts take control, Nozomi and Sayaka found themselves doing the downward dog yoga pose in sync.

Their butts wiggled and jiggled erotically in the air, and they could feel every inch of their sensitized skin tingling in response. They let out moans of pleasure, matching each other beat for beat, rhythm for rhythm.

Their bodies moved in perfect synchronization, as if they had been practicing this dance for years. The atmosphere in the room grew thick with their combined sweat and the scent of their arousal.

Nozomi and Sayaka bodies moved faster, their hips gyrating with more intensity. Their butts, now glistening with sweat, clenched and unclenched.

They followed up by assuming squatting position, still making their glowing asses quiver and jiggle like gelatin.

After standing up straight, Nozomi turned to Sayaka and held out her a hand, giving a cute smile and a wink that made her blush. Sayaka stood up straight, took her hand and allowed Nozomi to pull her closer.

Now dancing side by side, the two occasionally bumped hips with each other, which made their butts glow as the souls inside them moaned with pleasure.

It was a sight to behold, the two athletic women, their bodies glistening with sweat, their muscles rippling as they moved in perfect sync, their butts jiggling and bouncing, a symphony of flesh and desire.

The air was thick with the scent of their arousal, the sound of their moans and the slap of flesh against flesh filling the room.

Their bodies moved in perfect harmony, each thrust timed to the beat of their hearts, the pulse of their desire.

Even when the two girls stayed perfectly still, their butts shook like cell phones on vibrate did, all thanks to the entities inside their rears.

"Wow Natsume, you and Yuzu sure know how to shake it!" Nozomi commented.

"It's a little disconcerting... and yet..." Sayaka muttered.

Nozomi chuckled, her breath still ragged. "You can say that again." She turned to face Sayaka, her eyes gleaming with mischief. "Well, I for one can't wait to be your date for the butt wedding."

Sayaka blushed in surprised and smiled shyly as she glanced away. "Yeah, me neither..." she muttered while Nozomi giggled, as did their pulsating rears.
