Doki Doki Curvature Club

Monika and Sayori sat right next to each other, amid a rather special conversation. They were the only ones currently in the clubroom, having arrived together unusually early. The two weren’t at all strangers to discussing their feelings, but on this occasion, the feelings being discussed were, well, different.

Just a few hours prior, during another class, Sayori had watched Monika from a few desks down. She had observed her poise, her grace, her…curves. The way her chest rose and fell with her breathing. She hadn’t been, and still wasn’t, wearing a blazer, which only made the movements more visible. Sayori could hardly stand to watch much longer, and the sight summoned up her hidden insecurities with a vengeance.

At this present hour, Sayori had finally mustered the courage to discuss it with her friend.

“So…you were watching me breathe?” queried Monika, her features heavy with intrigue.

“I, uh…yeah…kinda…” was Sayori’s weak reply.

“And you’re jealous of my curves?” Monika tried to hide the creeping smugness that threatened to show on her face.

The cinnamon bun’s eyes darted left, then right, before giving a simple response.

“Yeah.”

“I can help with that, you know.”

“Huh?”

“Yup. It’s a nifty trick a friend from outside school taught me!” Monika stood to walk in front of her desk. “All you have to do is come here~”

With a dash of hesitation, Sayori arose and went to face Monika in front of her own desk.

“So, what are we…do…ing-”

She trailed off as, seemingly out of nowhere, Monika began to loudly inhale. Her boobs swelled rapidly to almost twice their size, filling with air and torturing the buttons on her shirt. A wide-eyed Sayori tried to piece together what the fuck was going on. What was Monika planning? It all became clear once she grabbed her friend by the shoulder, pulled her in, locked lips, and blew like the wind.

Sayori’s eyes shot wide open as the club leader’s breath poured in. Her own breasts steadily expanded, the feeling extending downward to her hindquarters. Her shirt and vest protested whilst her skirt rode up. The pressure grew as those parts continued to swell, round and taut, spurred on by Monika’s great exhalation. Then she pulled back, leaving Sayori with a heavily enhanced figure. The cinnamon bun looked herself over, taking hold of her expanded curves, those stupendous globes and astounding thighs. She now put Monika, Yuri, and well, literally everyone in town to shame.

“Woah…”

“Isn’t it amazing?” A wide grin was ironed onto Monika’s face.

“I…didn’t know you could just…do that...”

“Mhm! I forgot just how fun it is to do that, ya know!” That grin wasn’t going anywhere. “I think you could use a bit more though, hm? Make you the curviest girl in the world~.”

“Well, I mean…I don’t think-”

Too late. Monika had gotten a taste of inflation.

She inhaled again, sucking swathes of air into her chest until a button vacated her shirt from the sheer expansion of her capacious tits. Sayori actually felt her coral hair flutter in the draft, her expression a mix of fear and resignation. And then came the shoulder grab, the reel in, the connection of soft lips. Monika exhaled with air compressor-like strength, both girls’ cheeks bulging out immensely.

This time, the growth went like lightning. Sayori’s already bloated bosoms billowed out, each matching then exceeding the average exercise ball. Her own shirt buttons came undone, made visible by the sudden tearing of her vest down the middle. Simultaneously, the torrent of air flooded her ass, now on full display as her skirt slid over them. Her thighs ballooned into roundish masses, matching the obscene growth of her top end.

By the time Monika stepped away, her friend’s curves were preposterously bloated and tight. Sayori looked like a hellishly overblown caricature of her former self, and she knew it. She couldn’t even stand properly, having to instead sit on her tremendously inflated rear. But Monika looked insatiable, rubbing her hands at the sight of her companion full of the air from her own impressive breasts.

“Oh, you look absolutely amazing, Sayori!” chirped the gleeful club president, “You’ve got to have the biggest curves on earth by now!”

“Monika,” began, Sayori, brows furrowed and voice severely strained, “I literally look like a blimp right now! This is crazy!”

Monika paused, rubbing her chin as if deep in thought.

“Mmmm…bigger.”

A struggling “Nooo!!!!” left Sayori’s lips.

“Oh, but this is so. Much. Fun!!” Those last few words came out as a growl. Monika leapt onto Sayori’s swollen form, took a fabric-stretching breath, and began pumping in shorter but still tremendous gusts into her mouth. Huff. Puff. Puff. Huff. Sayori’s breasts and ass surged out more in time with these great exhales, the pressure within rising to an unbearable threshold. Desks were shoved aside as her body claimed the space around them. Monika rose higher into the air, riding on her friend’s expanding frame, continuing her breathy, blustery attacks. Sayori’s bra and shirt ripped apart as did her panties, now thoroughly incapable of keeping the burgeoning flesh at bay.

One last monumental inhale rang through the clubroom. Every last molecule of oxygen seemed to rush straight into Monika’s tits. They ballooned until another button was forced undone, reaching three times their usual size. Lightweight objects shifted and fluttered. Sayori’s blue eyes widened with raw horror.

And then came the final blow.

The desks and chairs rammed into each other as Sayori billowed out one final time. Her skin grew thinner, tighter, reaching that point of no return. A loud whoosh, mixed with a growing rumbling, was all that could be heard. She surged, and surged, and surged, and just kept surging with Monika’s gale-force, womanly hurricane…

BANG!

The detonation could be heard across the entire premises.

Coincidentally, at that very moment, Yuri and Natsuki had finally made their way to the door, knowingly late. Natsuki casually swung open the door, only to be greeted with the sight of Sayori, red-faced and nude, with a breathless but giddy Monika slouching beside her. The club leader snapped around to see her absolutely flabbergasted clubmates.

“What the actual fuck??!”

There was going to be a lot of explaining to do.

THE END.
