================

The entrance of the Tachibana family home, sunlight streaming in.

The finger pressing the doorbell trembled slightly.

"Oh, Sato-kun"

Kiyomi-san greeted him. Her refined features had clearly been passed down to her two children.

"To visit..."

"Thank you. But..."

A look of concern floated across Kiyomi-san's face.

"Both of them haven't come out of their rooms".

"Is that so..."

"I'm really sorry, especially since Sato-kun came all this way".

"No..."

"Would you like to stay for some tea?"

He was led into the living room.

"I'll go make some tea". Kiyomi-san headed to the kitchen.

Just then, he noticed something familiar on the table.

Anri-san's smartphone. The charging cable was connected.

"This is..."

He looked around and quietly reached out. The moment he touched it, an image flowed into his mind.

There, he saw Anri-san and Kokoro-chan.

Anri was standing with Kokoro in the plaza in front of the station. Both were in their usual jeans and T-shirts. But today, a heavy atmosphere, unlike usual, hung over them.

"Big sister... are you really going?"

Kokoro tugged at Anri's sleeve, looking uneasy.

Anri sighed deeply, recalling the scene from the other day. Many videos had been taken of them. Refusal was not an option.

"What else can we do? We had those videos taken of us, didn't we?"

Kokoro silently nodded at Anri's words. However, it was clear that neither of them liked this situation.

"Hey, both of you!"

A cheerful voice rang out, and Takeshi Katagiri appeared. His hair was styled more meticulously than usual, and he wore a casual but branded shirt. The purple cross earring in his right ear shone in the morning sun.

"Did I keep you waiting?"

There was a hint of triumph mixed in Katagiri's smile.

"No, we just arrived". Anri replied politely, but her voice lacked warmth.

"Alright, let's go then". Katagiri happily stood between them.

"Today, I'll buy you two some wonderful clothes. Especially Anri-san, it's a waste to always wear just jeans, isn't it?"

Anri's spine froze. She sensed something lurking behind Katagiri's words. Kokoro also walked closer to her sister.

"Hey, Kokoro-chan, I think it's about time you wore more feminine clothes too". Katagiri pointed to the large shopping mall in front of the station.

"That 'Candy Pop' store over there has a lot of cute dresses".

At that moment, Anri was convinced. This wasn't just a shopping trip out of kindness. Katagiri's abnormal obsession was gradually revealing its true nature. However, for now, they had no choice but to act obediently.

"...Thank you". Anri forced a smile and followed Katagiri.

As they went up the escalator, Anri's anxiety grew about what kind of ordeal awaited them. Katagiri's expectant gaze enveloped the sisters in an unpleasant premonition.

Upon entering the mall, they were led to a brightly lit store with a sweet scent. The walls were crammed with brightly colored dresses and skirts. Many of them were revealing designs that the two wouldn't normally wear.

"Look, how about this?" Katagiri picked up a particularly short dress. His eyes glowed strangely.

"It suits you beautifully!" The cheerful voice of a young female store clerk echoed in the fitting room. Anri couldn't hide her bewilderment at her reflection in the mirror. The pale pink dress was cuter than anything she normally wore. It was certainly beautiful, but at the same time, it felt unnatural. The hem was about 20 centimeters above her knees. Anri unconsciously tugged at the hem.

"You truly look wonderful. It highlights the length of your legs". Anri gave a wry smile at the clerk's words. Beside her, Kokoro was equally confused. The light blue dress had a design that made it seem a little too mature for a 12-year-old girl. The deeply open back boldly showed her back from her shoulders to her waist. Of course, the skirt length was also as short as Anri's, like a miniskirt.

"My eyes were right after all, weren't they?" Katagiri's voice was clearly tinged with satisfaction. The sisters shivered at his words, waiting outside the fitting room. Katagiri's words before the fitting were still ringing in their ears.

"There's something I want both of you to hear". Katagiri had a strangely serious expression in front of the fitting room.

"The clothes you choose today, you'll wear them home just as they are. Of course, I'll put the clothes you take off in my backpack, and that includes all your underwear..."

"Eh?"

"No way..."

He smiled for a moment and added, "You have no right to refuse". They understood that beneath the seemingly kind offer lay an absolute command.

"Well then, these two outfits are decided". Katagiri's voice brought them back to reality. Anri looked at her sister. Kokoro's face showed anxiety, but even more so, a sense of resignation.

"So, will you be wearing these as they are?" Katagiri answered the clerk's question immediately.

"Yes. They both look wonderful, so they'll wear them as they are". Tears of frustration welled up in Kokoro's eyes. But she couldn't speak out. She could only silently accept the clothes.

"I'll hold onto your jeans and T-shirts". Katagiri opened his backpack.

"I'll keep them safe". The menacing sound in those words.

"...Thank you". Anri's voice was tinged with bitterness. Their bras and panties, wrapped in their jeans and T-shirts, were also put inside.

The two emerged from the fitting room in their dresses. Completely naked except for the dresses. The length was short. Their expressions clearly showed the humiliation of their pride as karate practitioners being trampled upon.

"Now, let's enjoy the rest of our date". As they headed to the register, Anri looked in the mirror many times. She couldn't believe her own reflection. Kokoro was equally restless, constantly adjusting her hem.

When they left the store, the stares of shoppers bothered them immensely. They unconsciously walked closer together.

"Oh, that's right". Katagiri suddenly stopped.

"It's almost lunchtime, how about we take a break at a cafe?" Katagiri pointed to "Café Lumière" on the 3rd floor of the mall. It was a stylish space with large glass windows overlooking the city.

"I..." Anri hesitated.

"Let's go?" Katagiri's voice held the same intimidating tone as before.

The sisters stopped in front of the escalator. Unaccustomed to the short skirt length, they held down their hems with their hands.

"Shall we take the stairs?" Katagiri suggested maliciously.

"...The escalator". Anri mumbled softly. The stairs they would normally dash up were now to be avoided.

"There's a seat with a good view". Katagiri led them to a window seat. It was a stylish cafe where each seat was a private booth, ensuring privacy. A spot overlooking the plaza. However, the sisters' hearts had no room to enjoy the view. Even when sitting in their chairs, their gestures were overly cautious. Their usual dignified demeanor was gone, replaced by unnatural movements constantly fussing with their clothes.

Katagiri kept ordering. Pancakes with ice cream, pasta, pizza, and then drinks were brought to their table, when Katagiri suddenly stood up.

"I'm going out for a bit. Go ahead and eat". With that, Katagiri left the cafe. The two remaining sisters looked at each other with uneasy expressions.

"Big sister, are you okay?"

"I'm fine, but..." Kokoro looked at Anri's face with concern.

As expected, the food at the stylish restaurant was delicious, and since Katagiri didn't return, the two relaxed and continued to eat. After eating most of their meal and finishing their drinks, they settled down. Finally, Katagiri returned. He was holding a box.

"What's that...?" Anri asked cautiously, and Katagiri replied with a smile.

"As you can see. It's a medical enema". With that, Katagiri placed a box on the table that read, "Uses natural glycerin. For very severe constipation".

"Huh? No! You're lying, right? Stop! Please!" Anri realized what Katagiri was about to do. Anri protested desperately, but Katagiri remained smirking. Kokoro was also flustered. However, Katagiri had no intention of listening to their opinions.

"Come on, sit down quickly". The two were forcibly seated. Katagiri began preparations. He opened the box and started. Then, he slowly brought the nozzle closer to Anri's buttocks first.

"I won't hurt you, so don't worry". Katagiri said with an eerie smile.

"This is... absolutely not okay..." Anri tried to resist, but she was restrained as if by paralysis. People passing by could be seen through the window. Couples and high school girls glanced at them.

"They're watching us..." Although the table should have hidden them from below, Anri trembled her head with shame and fear. There were other customers in the cafe. Katagiri proceeded carefully so as not to be noticed by those around him.

"Please... stop..." Anri pleaded, almost crying. Kokoro also maintained an uneasy expression.

Smirking, Katagiri inserted the enema nozzle into her anus.

"Ahhh! Noooo!" Anri's small scream faintly echoed in the cafe. Kokoro, fearing the same fate the next moment, closed her eyes tightly.

"Now I'm going to inject the medicine into your anus". Anri trembled with fear. However, Katagiri mercilessly pushed the nozzle in. A cold, slimy sensation spread through her anus.

"Hmph! Stop! Please!" Anri protested desperately, but Katagiri didn't stop. He continued to inject another dose of medicine.

"Ahhh! Stop it! Ugh..." The medicine was sent into her intestines with intense pressure. Anri's expression distorted. In the same way, Kokoro was also paralyzed and had an enema injected into her anus.

A few minutes later, a change appeared in their bodies. Along with a feeling of fullness, an intense urge to defecate assailed them.

"Bear with it". Katagiri said that and then led the two out of the cafe and headed to the nearest park.

The three of them walked the road from the shopping mall to the nearest park. Kokoro and Anri walked with Katagiri, sweating profusely.

"Haah, haah, I'm sorry, can I go to the bathroom just once?" Anri pleaded.

"Bear with it until the park. Are you saying you can't hold it in the middle of this road?" Katagiri retorted to Anri with an astonished look.

"I'm about to go too, I'm at my limit!" Kokoro stopped, her face tearful.

"Alright, there are a lot of pedestrians, but are you going to do it here?"

"Ugh... no way..."

"Oh? Isn't that Tachibana? Shopping with your sister?" A boy with a middle-aged man, perhaps his father, who was shopping with him, spoke to Kokoro. The father's gaze seemed to ogle Anri. The beautiful girl's provocative bare legs stretched gracefully from her dress. Anri's chest swayed without a bra as she walked.

"Oh, Miya...jima-kun... Yes, shopping... we are".

"I see, I always imagined Tachibana in jeans, but that kind of feminine clothing suits you too".

"Yes... Thank... you... no..."

PFFFFFFFTTTTT

Unable to hold it in, a loud farting sound escaped from Kokoro's backside.

"Huh? Tachibana?"

"Miyajima-kun! See you at school again!"

PFFFFFFFTTTTTT

Kokoro, her face bright red, bade Miyajima-kun farewell and began to walk quickly. From her short dress, as she hurried, her buttocks were occasionally visible. Miyajima-kun's face was frozen in astonishment as he watched her leave, but Kokoro didn't look back.

"Is that okay? Your friend seemed to want to talk more, you know?"

"Ah... this is the worst... He heard me fart..."

PFFFFT PFFF PFFFFT

PFFFFT PFFFFFFFFTTT

Not only Kokoro but also Anri's backside echoed with farting sounds. As surrounding pedestrians turned to see what was happening, the two fought against their embarrassment, desperately trying to suppress their voices.

"Ahhh... they're watching us..."

"Nooo... the farts... stop, stop..."

While minding the surrounding gazes, the two desperately tried to suppress their voices. But Anri's stomach had reached its limit.

PFFFFT PFFF PFFFFT

PFFFFT PFFFFFFFFTTT

Farting sounds echoed simultaneously from both their bottoms. A couple walking nearby turned around to see what was happening.

"It stinks! Seriously? Those girls are spreading a terrible odor!"

"Oh my god! They were farting so loudly! They're so cute, but I wonder if they'll make it to the bathroom?"

"Ahhh... they're watching us... no no no"

"Nooo... the farts... stop, stop..."

"Good thing you two could hold in your poop with your karate-trained abs and sphincter muscles".

The two walked with their faces bright red and downcast. Katagiri looked down at them, smirking.

As Anri and Kokoro walked towards the park, they fought against intense stomach pain and the urge to defecate, their stomachs gurgling.

"Ugh... this is the worst... so embarrassing"

"No... I can't take this anymore..."

Anri and Kokoro walked, desperately trying to hold in their poop.

PFFFFT PFFF PFFFFFTTTT

PFFFFFFFFFFFFTTTTTTT

Regular farting continued from their bottoms, making passersby turn around.

"It stinks! Mommy! Do those big sisters want to poop? They're walking around farting so much!"

"Tetsu-chan, no! It's not polite to say things like that!"

The child was admonished by a woman nearby and fell silent.

They arrived at the park, and Anri and Kokoro desperately searched for a restroom, spotting one in the distance.

"The restroom! It's over there! Let's hurry!"

"Yeah... I can't hold it anymore either..."

Katagiri stood in front of the two as they tried to head to the restroom.

"Wait, not yet. Today we're going to practice relieving ourselves outdoors".

"What?! No way! We can't do that outdoors!"

"I can't... let me go to the bathroom! No... not outside..."

The two desperately resisted, but Katagiri forcibly led them in the opposite direction from the restroom. Anri and Kokoro's bodies were reaching their limits. Their rectums were distended to the maximum, their muscles couldn't hold, and excrement was about to come out naturally.

"It's coming out... it's coming out..." Anri cried in a trembling voice. There were children and families around. They couldn't possibly defecate in such a place. But the fullness and the urge to defecate wouldn't stop.

"Please... help me..." Kokoro pleaded desperately. Anri was suffering just as much.

"It's coming out! It's coming out!" Anri desperately tried to hold it in, but her limit was approaching. Kokoro was the same.

"Come here, it's okay. No one's watching here". Katagiri called from inside the large playground equipment. At those words, Anri and Kokoro's eyes widened. Indeed, it was quiet inside the play equipment, and there were almost no people around.

"Now..." The two struggled internally. However, the urge to defecate gradually intensified, and their bodies began to move on their own.

"Ah... I can't anymore..." Anri mumbled softly and weakly squatted down. Kokoro also sat down in the same way. The two simultaneously lifted the hems of their dresses, revealing their clean, white bottoms.

"It's coming out... it's coming out..." Once the dam broke, it couldn't be stopped. Just as their anuses twitched, a thick poop emerged, pushing their anuses wide open. The two simultaneously discharged a large amount of poop from their anuses.

SQUELCH SQUELCH SQUELCH PLOP! SPLAT! GURGLE GURGLE GURGLE...

"Haah... haah..."

"Ugh... haah... haah..."

"Heh heh, what a sight. Sisters shitting thick poop from their anuses and taking a public dump. Truly the lowest women".

"That's awful... We just pooped in a place like this..."

"Yeah... it's so embarrassing..."

Katagiri recorded a video with his smartphone. Anri and Kokoro were shocked by the fact that their miserable state was being captured on video.

"You're shitting all over the place here. What are you thinking in such a crowded area?"

"Nooo... don't record us... if this humiliation is recorded on video..."

"That's right... please... stop... We're already... finished".

Sadness and regret welled up. The uncontrollable defecation continued even if they wanted to stop.

PLOP GURGLE GURGLE GURGLE

Just then, a small boy and girl appeared in front of them. The boy was about the height of a kindergarten senior, and the girl was about the height of a kindergarten junior. Anri and Kokoro turned pale when they realized their actions had been witnessed.

"Hey, big sisters, this isn't a bathroom, you know?"

"That's right, this is inside the play equipment, so it's not okay to poop here!"

The two children spoke with innocent smiles. The children's words increased Anri and Kokoro's shame.

"We're sorry... we know, but..." Anri replied in a fading voice.

"We couldn't hold in our poop... We're really sorry..." Kokoro followed with an apology.

"Hmm... but you know, it's not okay to poop outside, right?"

"That's right, there's a restroom in the park, so the park will get dirty! You have to follow manners, okay?" The boy and girl gently admonished the two sisters.

"I can't take this anymore... I want to die..."

"Me too... I have no reason to live..."

PFFFFT GURGLE GURGLE GURGLE

"Ah... no... it's coming out..."

SQUIRT SPLASHHHH SPLASHHHH SPLASHHHH AHHHHHHHH

It was Anri who started urinating while defecating. Yellow liquid splattered vigorously. It splashed and stained the floor of the play equipment.

"Hee! I'm coming out too".

TRICKLE TRICKLE TRICKLE SQUIRT SQUIRT SQUIRT SQUIRT SPLASHHHH SPLASHHHH SPLASHHHH

Next, Kokoro began to urinate. Transparent urine poured down onto the ground.

"Heh heh, what a sound. Your pee. Look, the kids are watching too, aren't they?"

"Ahhh! They're even peeing!"

"This playground equipment is dirty and unusable now! Waaaah!" The girl started crying.

The two flushed and desperately endured, their shame at being seen mixed with the physical pleasure of relief from the pain of defecation and urination.

"Heh heh, what a magnificent sight. To think there are sisters who show such an undignified and pathetic display". Katagiri looked down at them with cold eyes, recording a video on his smartphone.

Katagiri smirked and gave his next instruction.

"Both of you, look at your poop".

They looked at their feet and saw a large pile of feces. Their faces turned pale.

"We... released this much..."

Facing the poop they had discharged, they were confronted with reality.

"We are... the worst..."

"It stinks! This playground equipment is unusable now! Because the big sisters pooped so much! You're the worst!"

"Why do you poop and pee when there's a bathroom? Why? Waaah!" The innocent children's words weighed heavily on their hearts. Anri and Kokoro deeply regretted their actions.

Afterward, Katagiri took the two out of the park.

"Don't ever do that again". Katagiri said coldly. Anri and Kokoro couldn't say anything back, only silently nodding.
