The loading screen displayed Takanashi Kiara surrounded by cartoon chickens frantically working. One of her songs gradually faded out before the screen changed over to a live camera feed.

“Kikkeriki!~” Kiara cried out as she waved to the camera. She carried with a smooth motion to Pavolia Reine, looping her arms around the other girl. “Hello everyone, this is Takanashi Kiara from Hololive English!”

Reine waved to the camera. “Attention please, I’m Pavolia Reine, Hololive ID.” She leaned into Kiara’s hug, but her eyes remained focused on a small table in front of them.”

Kiara giggled. “As you can see, we’re doing a collab with the latest Hololive popup cafe. Shall we get to it, Reine?”

Kiara and Reine looked at the snacks before them. Though there were only two, each was excessively designed to resemble the pair.

Kiara’s themed treat was a slice of orange cake, layered so that spongey tiers of cake crossed an orange spectrum with equally vibrant colored creams between them. Atop it was a light blue dollop of frosting with a candied orange embedded in it.

Reine’s was a large slice of blueberry pie. A latticework of crust styled after peacock feathers decorating the surface with a whipped blueberry cream forming a pile atop the syrupy baked fruits.

“Wow,” Kiara marveled as she looked at her cake. “They really went all out for the collab, huh, Reine? Reine?” She looked up to see Reine already eating her cake.

“Hm?” Reine looked up at Kiara. She didn’t seem embarrassed or ashamed that she already dug into her pie. She licked some blueberry cream from the corner of her mouth before she scooped another bite into her mouth. It was the perfect mix of sweet and tart, a refreshing taste that didn’t prove overly cloying. “Everyone has looked at them long enough.” She gestured at the camera and the viewers beyond it. “I want to tell them how it tastes.”

Kiara sighed and rubbed the bridge of her nose. “I suppose you have a point.” She scooped a forkful of cake to her mouth. It was more tangy than Reine’s, each bite filled with the delicate citrussy orange. The sharper concentration in the frosting, the more mellow throughout the spongy cake. “Oooh, this is so good! We might have to order more before-“

A new sound filled the room. It wasn’t the sound of fabric tearing, but numerous threads groaned in unison. Kiara was wracked with a strange sensation as she glanced over her shoulder and noticed her figure was…curvier than usual.

“Eh?” Kiara reached an inquisitive hand to her rear. She tentatively tapped her right cheek. ‘That feels a lot softer than usual.’ She chuckled nervously and was about to clear her throat. The fabric chorus sounded again before she could, and Kiara’s butt visibly bulged outward behind her. Her skirt squeezed the expanded flesh, but it wasn’t able to hold it back. Soft, thick, rounded cheeks swelled similarly to balloons but with a visibly soft and weighty aspect.

Two surges had taken place. It was not a continuous rolling outward. Instead, her butt leaped in size, filling more space in a matter of seconds. The growth was so intense and speedy that the force caused each cheek to wobble like jello roughly dropped on a table.

Another growth spurt added enough weight that each cheek started to lurch downward. They quickly bounced back up as their texture became springier with their size. Additional width painted Kiara’s hips in a smoother growth than her butt cheeks. Her skirt wrapped around her waist like a glorified belt and seemed smaller with each passing moment. The next growth caused fat to roll over the upper hem and bulge past the lower one.

The upper curves of Kiara’s cheeks piled high in sloped mounds, while the lower curves hung free with slightly flabbier textures. The surface of each cheek was a puffy-looking curve that resembled an overstuffed throw pillow.

Kiara tried to turn as if she could get a better view of her butt. This just revealed the basketball-sized cheeks to the audience. No matter the angle, Kiara couldn’t get a better look. Instead, she wobbled her thick cheeks as if to boast about their supple texture. Her butt wobbled like gelatin stuffed in a silk bag. It was a smooth, chaotic wave that implied intense weight but also incredibly soft texture.

Kiara had to grab the table for balance as her center of gravity was thrown backward. Her butt grew again, so her cheeks had doubled their already increased size. Her hips had grown to almost half her height, and the furthest curves of her cheeks were beyond arm’s reach. Most of the pale cheeks were exposed by this point. Her skirt covered a meager sliver of the bulbous cheeks and seemed primed to tear down the middle.

Kiara tried to adjust her skirt with one hand. She pulled it upward, only to stop as more of her butt cheeks were exposed from beneath. Her fingers stretched and pinched the skirt to pull it down. Again, more flesh was revealed. This time from above. Each gentle poke or pinch caused fat to squish or bulge. It was soft and distractingly warm, but Kiara didn’t want to focus on it.

She didn’t know HOW to feel about this. Everything was being witnessed live. The weightiness and uncontrollable wobble were difficult to manage. What was the right way to react? Should she try to hobble offscreen? No, she would certainly fall and give the camera a better view of her fat, wobbly ass cheeks!

“Um, Reine, a little help plea-“ Kiara froze as she looked at Reine. She moved her hands from where they cupped her cheeks to rub her eyes. Residual blurriness cleared, but Reine was still blue. Her skin had turned to a deep, vibrant…blue. “W-what happened to you?!”

Reine cupped her chin and hummed. “I’m not sure. My skin started to turn blue while your butt expanded.” She subtly gestured to Kiara’s enormous butt with her off hand. “I’m also not sure this is it.” She looked down at her gurgling stomach.

Reine’s belly bulged outward in a smooth, constant motion. This was more balloon-like, with every second seeing Reine’s stomach rounder and fuller. It quickly became as large as a basketball, then it doubled in size, and soon her sides began to bow with similar roundness. Her dress was pulled taut around her bloated midsection, especially as her back began to arc outward. Her entire lower abdomen was overtaken in a spherical shape that sloshed and gurgled loudly.

“Ooooh~” Reine moaned and placed her hands on her belly. She slowly ran her hands over the growing curve of her belly. Fingers tentatively traced the curve of what used to be a flat stomach but was now rushing to the size of a beach ball. Her skin buzzed with pleasure, which was heightened with touch. It didn’t require touch. The feeling became more and more intense by the second. Every new stretch or subtle movement was a spike in ecstasy.

Reine bit her lip, and her eyes rolled back in her head. She couldn’t get enough of this sensation, and she was lucky that it wouldn’t end anytime soon. The bloat of her belly continued until the furthest curve was beyond her arm's reach. Her sides began to curve and fill outward to half that length. Her back, too, was taken up in a new curve that made moving more difficult. Reine didn’t care, as the pleasure she felt was greater than anything she had ever felt.

The swell of Reine’s belly might have drawn eyes at first, but her chest began to demand more attention. Juice burbled and swirled as Reine’s breasts raced through cup sizes. They quickly outsized her head, then they doubled in size, and eventually tripled in size. Once they were as ripe and round as yoga balls, they began to discharge their juice. The front of her dress developed dark blue stains, then visibly dripped with juice, and occasionally they spurted short streams.

“It feels…so good…” Reine panted as she used the limited reach of her arms to grope her chest. A gentle squeeze was enough to provoke a spurt of juice. The deep blue liquid nearly reached the ceiling and the other side of the room, and it had started to pool at her feet.

Reine tried to rub her thighs together, but soon they were too far apart. Instead of growing thicker and squishing together, Reine’s pelvis rolled out with the greater sphere of her body. This pulled her legs into her until her groin reached the floor. Now her increasingly round and heavy body had to balance on her pelvis. This put all that weight and pressure on a delicate area, and that raised the ceiling of pleasure tenfold.

Kiara gulped nervously as she watched this. She had been worried about her butt, but Reine didn’t care at all. ‘Her entire body…and she doesn’t care.’ Kiara thought. She glanced at the camera. It was still live. Everything was being broadcast to thousands of viewers. The number shot higher as the news spread, and more wanted to see.

Kiara could stop the stream. It came to mind for a brief moment.

Kiara’s feet moved, but not toward the camera. She waddled to Reine, vaguely thinking of how her butt cheeks bounced and clashed together. That felt strangely good, but it wasn’t equal to the exhilarating tingle Reine experienced.

Kiara got on the tips of her toes, pulled part of Reine’s dress down to reveal a juice-drenched nipple, and she latched her mouth upon it.

“OOOOUGGG!~” Reine gasped and moaned. Just Kiara’s touch provoked a torrent of juice. It was so much that it leaked from the corners of Kiara’s mouth despite her greedy suckling.

A blue hue began to overtake Kiara’s skin. It started around her lips and nose before it spread across her face and down her neck. Her stomach had already swollen to the size of a volleyball. It began to turn blue, which made it look like a giant blueberry.

It didn’t take long for Kiara’s body to begin its juice production. That was around the time Kiara thought she was as full as possible. That sense of fullness grew more intense as Kiara started to swell similarly to Reine. The ecstatic tingle accompanied this fullness. It didn’t overpower or remove it, and instead enhanced the stuffed sensation. Kiara groped at her swelling midsection and moaned unabashedly. She trembled with pleasure as her body quickly bloated. It was like Reine’s juice was primed from her growth and offered a more rapid experience than her pie had.

There was no indication Kiara would outgrow Reine, but it was clear she’d match the other idol in mere minutes.

Just like Reine, Kiara’s belly reached a certain size. The juice was then forced toward her sides and back. This gave her abdomen the almost perfect sphere shape. Juice was pumped to her hips and broadened them, but this is where a distinction was made.

Reine’s breasts had taken a substantial amount of juice, but Kiara’s were only a quarter as large. Instead, Kiara’s butt rapidly swelled out behind her. Her shoulders rounded and followed a broad curve that started to tuck toward her lower abdomen, but it then sharply curved in the other direction to form massive arcs of her butt cheeks. It was almost like her body was composed of three spheres, but more juice helped to gently fill the jarring change.

This allowed Kiara to remain stable. Reine teetered back and forth in her twitching and moaning, whereas Kiara’s giant, rounded butt cheeks kept her upright. Therefore, she could remain upright as she twitched and moaned, spraying juice across the room.

Perhaps it was because of Reine’s teetering that she rolled forward. Kiara had never drifted far from the other berry, so Reine ended up leaning against her. Kiara’s stability kept them both in place as their blue skin brushed and rubbed together.

The pleasure that followed bordered mind shattering. No sense remained in either berry’s head. They tensed, and the juice inside them whirled. Their overfilled breasts now sprayed constantly, only furthering their pleasure. Their skin tingled, the taut feelings of their bodies built, and they continued to swell.

Even with how round and full their bodies were, Kiara and Reine continued to swell. This pulled their limbs further into their bodies, and their various assets continued to stretch. Reine’s breasts grew despite how much juice poured out of them, growing larger than her body used to be. They dumped enough gallons of juice to stain the floor and partially flood it, but that was beyond her concern. Reine just tried to shift her body anyway she could. She was desperate for more pleasure, and it was best where her skin touched Kiara’s.

Kiara eagerly drank this affection in. No matter how much Reine twitched or wiggled, she would stay upright. Her eyelids fluttered as she couldn’t quite focus on anything. She just tried to take in every detail of her growth. The stretch of her skin, the current of juice in her body, the intense tingle where Reine’s nipples rubbed or sprayed juice on her delicate skin.

“Oooooh~” Kiara suddenly groaned. She felt her butt hit something solid. She couldn’t turn her head, but one sliver of consciousness thought it was the wall. It became a new focal point of pleasure. Her body was stuck between that wall and Reine. The wall was too sturdy, and Reine was too heavy. Neither would move, so Kiara was squished and squeezed between them. The pressure caused her breasts to spurt more juice, though it wasn’t as powerful a stream as Reine’s.

The room the two were in was like a small studio. Their continued swelling already took up most of it, and would soon take up all of it. Their sides rolled out further and neared the walls to their left and right, their upper curves grew closer to the ceiling, and the camera failed to capture their entire bodies.

Reine was the next to touch the wall behind her. This increased the pressure between her and Kiara. Both were pressed by two points, each other and the walls. This soon increased to three as they touched the wall to their left, away from the camera.

The camera’s view was gradually consumed more by blue until that was all it took up. There was a slight difference in color and shape between Reine and Kiara, but it eventually didn’t matter. Their bodies came closer and closer until the camera was pushed against the wall. The sound of Kiara and Reine’s moans became more muffled until it was unintelligible.

The camera was squeezed to the point its lens started to crack, which was right around the time staff finally gained access and ended the stream remotely…

—

Shiori stepped out of the rehearsal studio and sighed. She wiped sweat from her brow as she walked to what appeared to be a water cooler. Yet, she discovered it was filled with juice as she poured it into a paper cup.

“Oh,” Shiori murmured and sniffed it. “Blueberry? Alright, I guess.” She tipped the cup back and drained its contents. The flavor was strong but incredibly fresh. She drained the entire cup without thinking. The fatigue from rehearsal vanished in an instant, and she was compelled to refill her cup. She took her time with this one, which allowed her mind to wander. The simple thought of where this juice came from made her think of two people she hadn’t seen in a while.

“I wonder where Kiara and Reine went off to?” Shiori thought aloud as the tip of her nose began to turn blue…

Meanwhile…

In a basement beneath Cover Corp. that not many were aware of, Kiara and Reine were tucked away. Behind a soundproof door, the two idols remained, the soundproofing needed to conceal the echoing moans within.

Kiara and Reine’s faces were in a permanent state of blinding ecstasy. Their backs were arched as much as their swollen bodies would allow while mechanical pumps worked tirelessly to harvest juice from their puffy nipples.

“O-oh again…I’m gonna…ag-gaaaain~” Kiara moaned and shuddered, curling her fingers as pure pleasure soaked into her bones. Being juiced like this had somehow been more pleasurable than being squished against Reine. While that was fun, Kiara could only think of how good it felt to be juiced.

Even if her mind wasn’t drenched in pleasure, she wouldn’t ever leave this room. The constant juicing had reduced the weight and roundness of her upper body, but she still looked like a giant, blue pear. Her legs were still pulled into her body, and her butt was so wide that there was no way to move it from its place. Even rolling would lock her into a circular pattern.

That wasn’t even to mention how she’d get upstairs.

Reine moaned unintelligibly into her cleavage. She was just as helpless as Kiara, simply in a different way. Her lower body had reduced in size from her juicing, but her breasts seemed even larger. They dominated her body and rested upon the ground. She could potentially get her legs beneath her, but there was no way she had the strength to lift her chest. There was no way she could roll over or drag them either. She was anchored in place.

Both could potentially leave one day. There was the chance their juice-filled bodies would cease to replenish. Though perhaps that wasn’t anyone’s plan. Otherwise, they wouldn’t put the juice where anyone could wander by and fill a cup.

THE END
