"Luka-chan," An especially bouncy MEIKO bounded into another classroom of the Classroom Sekai,an overjoyed look on her face as her uniform struggled to keep up with all the jostling beneath it. "Did you hear the rumors?" She sneered, besides herself with happiness as she met eyes with her fellow virtual singer. Trotting up to Luka's side, Meiko acted unusually childish, twiddling a lock of the girl's hair between her fingers as Luka tried to practice.

"Meiko?" Surrendering to the other girl's pestering, Luka turned to face her with a little chuckle. "Whatever's got you so worked up, it must be good~!" She laughed, setting aside her guitar and getting ready for the gossip-bomb of a lifetime. With the majority of Leo/Need having gone their separate ways, they'd practically abandoned their beloved vocaloids to a fate of neglect — that, and gradually getting plumper under some unseen force. So, it was only natural for Luka and Meiko to be positively enraptured by the prospect of some kind of gossip.

"M-Meiko! Haah! Meiko, s-slow down!" From almost the other side of the building, the sound of what could only be a stampeding elephant could be heard. "P-Please!" It wheezed, exhausted and on the edge of raggedness. Meiko's ear pricked when she heard it, shuffling in on Luka as if she was afraid of the massive beast catching her up.

"Did you hear?" She whispered, her childish excitedness quickly replaced with her usual, slightly seductive motherliness. "Honami and Saki, they're..." She teased, running a finger along Luka's thigh as if that'd actually do anything. "They're getting fat." She hummed, right into Luka's ear, beaming as she saw the cheek it was connected to burst into a furious blushing.

"Getting fat?!" Luka exclaimed, almost toppling off of her desk as the news hit her, square in the face. She hadn't even seen Saki or Honami in years, having made do with the daily visit from Ichika, and their own escapades. To think that an entire half of Leo/Need had gotten fat perplexed her beyond measure. They'd been so stern and studious — even if they loved to have fun — that Luka could hardly even imagine them as a flabby band.

"What's more," Meiko didn't stop, drinking in the way that Luka reacted to the news. Like some kind of succubus, she curled about Luka, forbidding any chance at a retreat. "they're getting fat on purpose!" She finally giggled, her free hand patting Luka's slightly plump tummy as she did. Finally, Meiko knew exactly why they'd started fattening up; Saki and Honami's brains were so polluted with thoughts of getting fat, that they'd extended the effect of their own gluttony into the Sekai.

"Meiko-s-san!" Still beyond bedraggled, the source of the voice became more apparent as soon as Meiko finished when she had to say. "Meiko-san, please don't..." Mochizuki Honami's already weary voice trailed off as she landed on the truth. Meiko had given away her secret to another Virtual Singer, and clearly planned on having no end of fun with it. As Honami waddled into view, the effects her appetite had been having on her own body became apparent; if the Virtual Singers had gotten chubby off of their thoughts, then it was no surprise that Honami herself had turned into something almost amounting to a blob.

"Oh!" Meiko snickered, turning about to see the fat drummer ooze into view. "Honami, so kind of you to join us!" She smirked, slinking about the classroom until she could lean against the doorframe. After all, Honami was so wide that she might not even be able to fit through it. "We were just discussing something fun..." Meiko's eyes slimmed down; all three of them knew exactly what she'd been talking about — after all, the virtual drummer was staring right at Honami's belly.

"Ughh..." Honami wheezed, clutching her belly in both hands as she blushed. Still oh-so tired from climbing a few flights of stairs, Honami's clearly three-hundred kilo body seemed to puff out superheated clouds of sweat and exhaustion. "You P-Promised, Meiko-san!" Honami gasped, on the verge of tears. "Saki-chan and I are just..."

Before the panting piggy could finish her sentence, Meiko leapt in, letting Honami's throat rest for just a moment. "Just a bit of fun?" She teased, leaving the classroom with Luka in close pursuit. "You know, we're not too bad at that ourselves!" Meiko rubbed her own belly now, pushing the buttons apart with her thumbs and exposing the soft, squishy flesh beneath.

"That's what we're afraid of!" Honami wailed, watching helplessly as Meiko grabbed one of her arms, and Luka seized the other. "You two can get a bit—!" Unable to finish herself once again, Honami whimpered as a thick, goop-filled bun was shoved into her mouth.

"Overexcited?" Now, it was Luka's turn to have some fun with the fatass. Generating a virtual profiterole in one hand, Luka slunk it towards Honami's greedy mouth. "Well, it's just your fault for leaving us alone, for so long~!" Luka smiled, honestly overjoyed to see Honami again, no matter what shape she was in. After sliding the profiterole into Honami's plump cheeks, Luka's free hand slid down, over her huge boobs, and onto an even huger belly. Squidging the soft mass as it hung out of a loose t-shirt, Luka smiled at Meiko, and nodded.

"You — Omff — You dwoo!" Honami squealed, feeling her face fill up with food as her thick body grew ever so much rounder under the two girl's stewardship. "Shtop!" She moaned, growing another inch more rotund as she swallowed a mouthful of slop. "I'm sho f-fat alweddy!" Honami blubbered, trying to free herself from the two; but then, her own elbow squished into something immensely soft. Soft, and growing.

"You are!" Meiko grinned, pulling Honami's arm in close enough that she could feel just how much fatter she was becoming. "You really are fat, Honami!" With that, the buttons down Meiko's blouse started to burst. "And so are we!!"
