Commission

——

Label felt her heart pound in her chest as she rushed down the hall. She couldn’t remember the last time she was bathed in this much light. She was so used to the darkness of her room, she was so used to being in her room 24/7! That and her brisk pace had her breathless, but this frantic adventure was worth it!

Clutched to Label’s ample chest was a book. It was clearly old and hardly bound together, but it was from the forbidden library. Arcana had done Label a great service by finding it, and all Label had to do was return to the safety of her room.

The door was opened and slammed shut in a single second. Label was back in her disheveled room, and her eyes adjusted to her preferred level of light. Just the dim luminescence of her computer screen. It was all she needed…

“Hehe…eheheheh!” Label started to giggle with more and more intensity. A lecherous grin had stretched across her face as she looked at the book. The cover was unintelligible, but she opened to a bookmarked page. “This book was considered a joke or a legend back when it was written. Today it was just a tall tale, but I have it for real!”

Idealization of the feminine form.

That was the spell Label needed. Spell might have been the wrong word, though. It was much closer to a line of code. One might even call it a cheat code. Something designed to manipulate the Vapaus all Nikke possessed. The origins didn’t matter. What Label cared about was this specific code and how it would make the Commander fall for her.

Label started to read it, letter by letter. The second it was complete, she felt a pressure in her chest.

Label was already well-endowed. Her black dress held her breasts back like a struggling dam. Her eyes widened with astonishment as she watched her chest swell. The soft, supple mass of her breasts swelled like a balloon filled with air. They became rounder, pushed out further, and even seemed wider. By the time they stopped growing, they had become wider than her shoulders and stretched half her arm’s length.

“I-it work…it worked!” Label cradled the book in one hand and used the other to grope her chest. Her fingers sank into her sweat-coated flesh with ease. The softness enveloped her digits up to her second knuckle like nothing. “Ehehe, the Commander will probably grab more roughly than this. I should give him some more to grab~” Label said with drool running down her chin.

Label read the code again, and the pressure returned.

Her bust expanded once more. Flesh rolled over the front of her dress and bulged around the sides. The spaghetti straps sank into her flesh like baking bread wrapped in twine. Label looped one finger around a strap and tugged it. One of her breasts bounced and rolled before its jiggles carried into the other. She could feel the weight of her breasts, but they were incredibly springy. They hadn’t lost any volume or started to sag.

“This practically is magic. A spell to make the Commander fall madly in love with me!” Label now cupped her cheeks and shook her head back and forth. She giggled like a schoolgirl despite being the textbook definition of a shut-in neet.

Label noticed something during this shaking. There was some unfamiliar movement on her lower body. One eye peeked over her shoulder and suddenly widened. “Here, too?” Label twisted slightly for a better look. Her butt was much rounder and thicker. She had been so distracted by her chest that she failed to realize her butt and hips were also impacted.

Label placed the book down and reached both hands behind her. It was difficult to see, and she didn’t have a mirror. She needed her hands to take enthuse details. Her fingers were spread wide, but still only touched her cheek. Her pinkies felt the inner curves, her index and middle stretched across most of the ample cheeks, but only her middle fingers could touch the lowest curves before her thumbs felt at her softened hips.

Label’s face turned from pink to red-hot. She could’t shake her smile, and her brain flooded with ideas. “H-he can stuff his face between my breasts…eheh then smack and grab my butt. Mmm, but I could go bigger. There are some Nikke already this stacked, so I need a body that puts them to shame. A body so curvy and soft that Commander will only think about me!”

Label could have simply repeated the code, but that was redundant. Why would she do that when there were other codes beneath? The ones made with bigger in mind. Label skipped down two lines and started to read.

She felt a more intense pressure. It radiated mostly from her chest and lower body, but it felt like a trail flowed across her entire body. She couldn’t see it beneath her chest, but her belly started to subtly grow. The belt around her stomach strained as flesh built beneath it. A soft gathering of pudge built. It swelled more and more, morphing into a sizable belly that bulged around the belt and hung to Label’s upper thighs.

That small stomach was overshadowed by Label’s breasts, which took a staggering leap. Her arms shot out to catch them as they literally leaped forward. The growth was so rapid and of such an amount that her upper chest slammed into her chin. Dazed, Label looked down to see the abundant flesh cradled in her arms.

“Woooooooooooo-!” No words left Label’s mouth. Just a noise of astonishment and joy as her breasts had become as large as beach balls. They weren’t as round, but that was fine. Label much preferred the enlarged, natural shape of her breasts. She could feel them morph around her arms, bulging over and sagging from beneath. She pulled her arms closer to her core, which provoked her bust to bulge even more. Now the fat rose gently, and she could rest her chin in her cleavage.

“So much…me! The Commander…I’m gonna be able to bury that broad, burly chest of his~” Label couldn’t resist and dipped her face down. She proceeded to roll her head back and forth, shamelessly motor boating herself.

These movements carried through Label’s body and created equal motion in her hips and butt. Her hips had stretched out to more incredible widths, as her breasts had. She was so wide that there was no way she could shimmy through her room’s narrow doorway. It would be harder if she turned sideways, as she would contend with her ample bust and full butt.

Label’s butt cheeks were incredibly thick and round now. They hung to her upper thighs, and their width was half the length of her legs. They were as broad as couch cushions and easily three times as thick. It was their absurd size and perhaps the difficult viewing angle that helped hide the new thickness of Label’s thighs. Like her belly, her legs had filled with new thickness and fat to match the egregious increases to her chest and butt.

“This could be enough, but is it?” Label asked. The answer was obviously no! There was an entire page of codes! Why would they exist if they weren’t better than the ones before?

Label swallowed hard and looked to the bottom of the page. This was the longest code of all, and Label was so excited that her voice trembled. She had to get it right, she had to see how big it would make her. The effect hit the second she finished speaking.

It was an all-encompassing rush that flowed through her. Label felt her entire body begin to puff and swell like rising dough. Her chest, hips, and butt continued to grow, but they were slower. The brunt of this latest growth hit areas yet to expand.

First, Label’s belt snapped as her belly rushed forward. It was so rapid that it tore the front of her dress. The pale flab was exposed and poured over Label’s thighs and down to her knees. It stretched as wide as her hips, developed a flabby roll toward the middle, and thickened enough to lift her already massive breasts.

“Wait, this wasn’t supposed to happen!” Label grabbed at her belly in surprise. “I was just supposed to enlarge my chest and hips. I don’t think the Commander will like this-“ Label stopped talking as her mind went full speed on delusions.

Giant boobs were soft and squishy, her added hips and butt were, too. So, why wouldn’t her belly be just as good?!

Label looked to her left, then her right. Her slender arms started to swell, too. Her shoulders had thickened slightly to help support her chest. Now her upper arms bulged and hung like overstuffed pillows. Each became as broad as her individual breasts, and their weight was staggering to contend with. The sweater that Label wore loosely had its sleeves filled to bursting with new flabby blubber.

Label’s lecherous grin returned. “I could wrap the Commander up in these Use the weight to push him deep in here” She reached over her chest to trace her fingers through her cleavage. “And this will be comfy, too” Her hands went further to the new curves of her belly. “I might be able to lie on top of him. He’d be completely buried under all of me”

Fear and surprise were already long gone. Label was fully onboard with her growth, which was good. It hadn’t stopped yet and didn’t seem likely to. Her body became fatter and noticeably heavier.

Label’s legs buckled under her weight and jiggled with their new thickness. Each of her thighs had swelled until they were as broad as her doorway. They curved and bulged like lopsided barrels before they couldn’t keep her balanced.

The entire room shook as Label fell on her butt. The thick cheeks were all that kept her from rolling helplessly onto her back. They had enough width and height to support the obese Nikke. They kept her in an upright seated position, just like a wooden wedge could jam a door open.

Label’s belly acted somewhat like a table before her, only soft and curved at its edges. Her breasts partially rested atop it, but their outer curves sagged off to the sides. Her upper arms were heavy enough to restrict some movement, but her doughy forearms were nimble enough for some tasks.

Like retrieving her phone. Label opened BlaBla and found the Commander.

Come over quickly. I need to show you something.

Label placed her phone down and began to giggle uncontrollably. Her body rolled in waves, quivering like jello dropped from its dish. “The Commander is coming. He’ll see how soft and plump I am I bet he’ll throw himself right on top of me First we’re gonna…then we’ll ehehehe~”

Label continued to fantasize as more growth wracked her body. Everything continued to thicken, with some areas like her breasts and butt becoming rounder. Meanwhile, her belly took on a flabbier state with a solidly established roll in the center. Part of Label thought of all the lewd things that could be done there… Unfortunately, her arms were too short to reach and tease the deep fold. She’d have to ask the Commander for that help.

Label didn’t think about how the Commander would react. He’d open the door to see most of the room’s space filled with a squishy pile of Nikke. He’d see how her hips were wedged between her bed and the opposite wall, how her butt cheeks overtook her desk, how her belly went on to stretch three arm lengths in front of her, and how her breasts piled up so her face was only visible when seen between their cleavage.

It would be quite the surprise…
