"Mō, yada!" Suisei pushed the plate of vegetables away disgustedly.

Anemachi scoffed at her younger sister in response, "If you want me to cook more, you should be grateful for what I make. We're not living at home with mom and dad anymore, y'know?"

"Hmmf—" Suisei huffed with her mouth half-full as she tore into her steak. Her diet after moving out had suffered, sure, but she was too proud to admit that out loud to Anemachi. The two sisters living on their own for the first time had brought about many new responsibilities to juggle. The general housework like cleaning, shopping, laundry, and for Suisei her work streaming, trips to the studio, vocal lessons and dancing practice, meant she would often not have time to cook or eat a proper meal until late at night. By then, she'd be so desperate for something to quickly satiate her hunger she'd default to ordering Uber eats or coerce friends to join her for yakiniku. "You know I've never liked vegetables, ever since I was little."

Anemachi sighed wistfully, "I know, but I thought now that you've grown up your tastes would mature a bit, too."

Suisei ignored her older sister's comment and continued ravenously eating. The young woman's appetite belied her figure—it was slim and elegant, and though she was often teased for her small chest, she otherwise had a feminine physique. Her high-pitched voice of childhood had naturally mellowed out to a deeper tone during puberty, yet her range still extended up to reach the high notes. "Thanks for the meal~" Suisei crooned as she finished her supper and stood up from the table to walk away.

The singer stopped suddenly in the doorway, cradling her abdomen. Anemachi scrutinized her for a moment, then asked perceptively, "Are you… going, regularly? I know you get so busy lately you often disregard your health. And stress tends to back you up."

"Grr…" Suisei ground her teeth. It had been a while since she last went. What day was it— Sunday? So it's been… 7 days? That was quite long, even for her. She was hard at work on songs for her next album and had been suppressing the urge when it came up; something she learned how to do particularly well over her years of streaming. "It's fine. I'll go tonight." Suisei exited the door frame and continued down the hallway out of sight.

Anemachi gathered up the dishes from the table and collected them in the sink. Suisei's income afforded them more luxuries than most, but automatic dishwashers were still uncommon in Japanese households, so the sisters would take turns doing them by hand each day. Anemachi added soap and filled the basin with hot water. Sticking a finger in the foam until it reached the desired temperature, she wiped off on a towel and grabbed a pair of bright pink rubber gloves—her favourite colour—and began to scrub away at the dirt.

* * *

"Onee-chan!" a voice called out from down the apartment corridor. Anemachi was nearly finished washing the dishes, so she shook her hands and with a Plap! Plap! pulled off both gloves, turned them inside-out then hung them to dry above the sink. "I'm coming!" she bellowed, and then as she got closer, "Where are you?"

"It's stuck." Suisei was sitting on the toilet, her black spats pulled down to her shins with both hands folded on her lap, covering her bare crotch. "It's stuck and won't come out!" There was a slight whimper as she spoke.

"Well, I can check if we have some medicine you can take—"

"No, you don't understand," Suisei briskly cut her off. "It's stuck partway and won't budge anymore. It hurts! I'm afraid it might tear!"

"Hmm…" The pleading look on Suisei's face made Anemachi realize she was serious. "OK. Then… let me take a look?" asked the older sister.

Having grown up together, the siblings shared a bath often during their youth—and occasionally still did in adulthood—so Anemachi wasn't unfamiliar with seeing her sister's private parts. Nevertheless, being comfortable with nudity was one thing, but what faced Anemachi next was a new level of intimacy.

Suisei slowly stood up from the seat and turned around to face the toilet, leaning her weight with one arm on the tank and keeping the other hand concealing her vulva. Dark, wiry pubic hair peeked out the sides of Suisei's cupped hand shrouding her mons pubis. Some stray hairs continued all the way up her taint and encircled around her anus. Against the pale white skin of her butt contrasted a brown circle of poop which stretched Suisei's asshole open, nearly 5cm in diameter. It protruded outwards 2 or 3cm, and was dry and hard with a cracked texture.

"Oh my, that does look painful," said Anemachi emphatically. "And you're certain you can't push anymore?"

"I've tried! It… gets a little further but then it… goes backwards to this point," Suisei answered ashamedly.

Anemachi rubbed her chin in contemplation, then said "I have an idea. Wait here." and left.

As Suisei stood alone, she began to get a whiff of the smell that had previously been trapped within the toilet bowl while she was sitting down. Suisei's mostly meat diet gave her bowel movements a powerful odour, and this one seemed especially pungent. Just how much had she eaten in the past seven days? There was yakiniku with Miko on Monday, omurice on Tuesday, she ordered okonomiyaki late on Wednesday, Anemachi made curry on Thursday, sukiyaki on Friday…

Suisei snapped back to the present when she heard Anemachi return and set down some items on the counter behind her.

"Here we go!" Anemachi said as she pushed the turd back inside Suisei unexpectedly. "Huuugh—!" Suisei shivered, the relief of her sphincter shrinking back down and the feeling of the long hard shit pushing against her bladder causing some pee to spray out; the stream hitting the palm of her hand guarding her crotch and spattering out in all directions.

"What are you doing?!" Suisei screeched.

Suisei's anus clamped down around Anemachi's finger when she pushed the poop back in, but she swiftly withdrew her hand and watched as the hole remained gaped open for a moment before winking shut.

"Sorry, but I thought if I explained my plan first you'd stubbornly refuse," said the elder sister, matter-of-factly.

"I trusted you enough to ask for help, you can at least return the favour and tell me what you're going to do!"

"Fine," Anemachi shrugged and began to explain, "I figured it wasn't going any further out, but it could it least go back in where it came from."

"How is that supposed to help me?! Am I expected to just never poop again?" Suisei exasperated. "—and wipe that smirk off your face!"

Anemachi had started grinning after hearing the aspiring idol's rhetorical quip. "No, that's not what I meant. There's a second part to my plan." The older sister held up a clear plastic bottle with a coloured flip cap. "We need to lubricate the way so it doesn't get stuck again."

"Oh…" Suisei's voice calmed down compared to her earlier outburst. "Well, that's the first somewhat sensible thing from you so far." Suisei glanced down at Anemachi's gloved hand as she began squeezing out the viscous liquid. "But are you sure this stuff is… safe?"

"Yeah I use it all the time when I mast—" Anemachi caught herself, and decided to rephrase. "Yes. It's safe." The sisters awkwardly stood in a silence punctuated only by the Squelch! as Anemachi finished covering her gloved hand with a copius amount of the thick clear lubricant. "OK. Are you ready?"

Suisei eyed her sister's hand one last time before nodding and presenting her backside.

"I'm applying it now," Anemachi said softly. Suisei felt a cold, wet sensation as the lube contacted her skin. Goosebumps formed on her arms. After rubbing the outside of her anus, Anemachi slipped her index finger inside. "Mmf-!" Suisei audibly protested the intrusion while biting her lower lip.

"Sorry. I should have warned you I was going in."

As Anemachi rotated her finger around to apply the lube evenly to the inner ring she occasionally pressed against the troublesome log waiting at the entrance behind Suisei's backdoor. The jostling reverberated down the length of the solid excrement, each time reminding Suisei how deep in her belly the situation extended with a quiver.

Once she felt satisfied with her application, the older sister pulled her finger out and lightly spanked the younger sister's pale buttock to indicate she was finished. Suisei reflexively touched the spot as she straightened up and turned around to face her. Before Suisei could complain about the treatment, Anemachi handed her a plastic bag.

"If you've got a week's worth of that," she pointed at Suisei's tummy, "you'll clog the plumbing for sure. There's only one toilet in this apartment. You're not gonna make me suffer for your bad choices. Put it in here." She shook the bag in emphasis.

Suisei blushed as Anemachi left her alone once again. Even she had to begrudingly concede, the odds were high that this would break the toilet if she tried to flush it. The apartment complex had a plumber on call, but the thought of a man coming in and dealing with her waste seemed more shameful to her than using the bag.

Suisei pulled her spats down the rest of the way to her ankles and stepped out of them with one foot, kicking them off to the side with the other. She laid the bag down on the floor and flattened it out, then squatted over it, centering herself as best she could. She commenced pushing again, her internal walls gripping the loaf and moving it downward. 3cm… 4… 5… it quickly reached the point of obstruction without much effort—perhaps the lube was helping, or the squatting position offered a better angle for her bowels.

Oh no, don't get stuck again! Suisei pleaded. She refocused and took a deep breath, then pressed down hard with her abdominal muscles. Her asshole spread wider. Tears formed in the corners of her eyes. The shit continued to inch outward haltingly, Suisei straining arduously as her anus dilated even further to an unthinkable 6cm across. The passage slowed as the tip of her poop gently reached the ground and rested, the remainder still hanging out of her.

Then, just as she thought she wouldn't be able to continue, with a final grunt Suisei pushed past the widest part of her feces and a stream of thinner softer poo accelerated out, her sphincter undulating rapidly as more solid bits were interspersed. Her eyelids fluttered involuntarily while the waste coiled up between her feet. "Oooooh…"

At last, it was free. Her cheeks were burning red from the effort, embarassment, and perhaps a little arousal. Her heart was beating fast and she was short of breath like after finishing a live concert. Her body now had an amazing feeling of emptiness. She felt so much lighter. Ogling the mountain of poo she had created, she was somewhat awestruck. All of that was inside me?

A translucent drop dribbled out from underneath her, leaving a thin connected strand leading from the floor back up to her sex. All the pain and anxiety she had felt during the whole ordeal had buried her horniness within. 'Going' wasn't the only thing she hadn't done in a week. With the release of her shit, her bottled up libido was now starting to bubble over and leak. She reached down to touch the increasingly burning spot in her loins and began masturbating, her slender fingers parting the pubic fringe and caressing her clitoris.

Suisei had long harboured a fetish for gloves—principally for fashion—she's made it publicly known that wearing rings over the top of gloves really gets her going. However, as one spends time immersed in a subculture, they start noticing other aspects of that thing they appreciate. For Suisei, style was the primary kindle of her passion, but as she discovered all the different varieties (fingerless, open back, ones with frills, the kind worn by butlers, leather, rubber, surgical and more) she identified the facets of gloves she liked most. Eventually any sort of hand covering fit her criteria.

The box of disposable latex gloves that Anemachi left in the restroom were bog-standard and far from fashionable, but Suisei could appreciate that they still had some of what piqued her fixation and they would do in a pinch. She took two out of the box and pulled them on, the latex quickly causing her petite palms to start sweating.

Normally touching such a dirty place would have been a turn off, but the glove barrier gave a protective feeling as Suisei inserted an index finger in her bum. She knew that inside the glove her fingers remained clean, albeit sweaty. The juxtaposition was turning her on more. She slid her middle finger alongside to join the first, the extremity reaching ever so slightly deeper.

Suisei continued fingering herself and her asshole, but it was becoming apparent that even two digits were not enough to satisfy her needs. Suisei gazed at the pile of dung on the ground. The hardened tip that had caused this whole mess in the first place was sticking out, covered in a glob of lube from when Anemachi was rubbing it on the inside of her hole.

Am I really… considering that? she gulped. The smell was starting to make her kind of dizzy. It was so strong. Normally the scent was masked somewhat inside the water, but with her feces laying out in the open air it lingered like a thick humidity in the room. With every shallow breath Suisei took, it intoxicated her further.

Tentatively, she reached out and touched the load with her gloved hand. It was a different sensation than what she expected. The glove disguised the feeling; it was neither slimy nor wet. The warmth, however, did penetrate through. Her heart beat faster.

The lump was surprisingly hard. Granted, it was the section that had been trapped in her colon for the most time. From the end, it extended 16cm long before another lighter-coloured, softer section began—a core sample of her diet during the past week. Gingerly, she picked it up and the firm part separated, leaving the rest behind.

With her free hand, she pulled a cheek aside then guided the lubricated head to the entrance of her asshole. It tickled as it brushed against her skin, still wavering in hesitation.

Finally, she took a deep breath and pushed inward. Her tongue involuntarily lolled out of her mouth as she experienced the now familiar sensation of her innards expanding. It was so much thicker than her fingers. She alternated pushing in with her hand and out with her abdominal muscles, each time going a little deeper than the last as the lubrication turned the entire length slick. She vigorously rubbed her clit and pushed the poop all the way in, the tail end disappearing as it was sucked in by her sphincter tightening closed. She shuddered as an orgasm washed over her, feeling the weight and the fullness as her shit came to rest again in her rectum.

*knock* *knock* Anemachi rapped at Suisei's bedroom door. "Are you streaming?"

"No, I'm just working on some thumbnails. Come on in." Suisei twisted around her chair.

"I don't mean to stay long, but I just got back from the conbini and picked up some stool softener for you." She held out a small white box.

"Oh, thank you!" Suisei accepted cheerfully.

"Well… I'll let you get back to your work," Anemachi awkwardly turned to leave and then remembered, "Oh! I'm making your favourite steak tonight for dinner, so don't forget to come out to eat!" softly closing the door behind her.

Suisei spun her chair back to her desk and slid open the drawer. She indiscriminately tossed the package inside towards the back, where it fell somewhere hidden behind a new box of blue latex gloves and a freshly opened bottle of lube.

Suisei rubbed her hand on her stomach and smiled to herself, "I wouldn't miss it!"
