Long before the time of a portly plumber, flurries of Star Bits whisked throughout the sea of cosmos and stars drifted astray in the perpetually expanding universe - the cycle of life, organic or not, was all visible to the maternal eye of Rosalina. Rosalina was a tall figure that was always a constant source of kindness and empathy. Even with her unfamiliar anatomy to the Lumas, her body was always noticeable from a distance. Hidden underneath the cosmic dress was a lithe, supple torso that really was never revealed to the public - and it never bared any mark to her dress besides its form.

Glancing through a telescope was a daily occurrence -  it reminded her of her life on her home planet. But, reminiscing would get her nowhere - she was flocked with juvenile Lumas; her children, her future. Removing her eye from the lense of the telescope, she casually strolled through the Comet Observatory, her floaty steps pressuring the red carpet underneath. Lumas of a varied set of colors drifted to each other, spinning, laughing, giggling. It brought a calm smile to the motherly Rosalina - seeing her kin overjoyed. It was contagious. The atmosphere was pleasant on the Observatory, just as it always was.

A weary Luma levitated slowly to the general direction of Rosalina, and seeing its discord made the cosmic deity depressed. She could read emotions off her little Lumas; this one was not content, nor displeased - this one was anxious, even fearful. Rosalina approached it, her wand not being habitually twirled.

“Mama…” the Luma muttered. It scratched the back of its star-shaped vessel. “At the Terrace, there’s a giant comet of Star Bits, heading straight towards us…”

Rosalina sustained her calm nature through the conversation, always ready to ease the emotions of her children. “Now, now, Luma, there is no need to be upset...just because it is going fast does not mean it bares any harm. You and your friends will be safe…” Rosalina comforted the pale Luma. It returned to its happy expression, dancing around to represent its thankfulness. “Thank you, Mama! Star Bits are tasty. I’m going to eat some with my friends!”

“Such innocence,” Rosalina happily thought. The pure, carefree behavior was one of Rosalina’s favorite things about her children. Questioning the Star Bit comet, she daintily approached the grass-covered terrain of the Terrace, and glanced to the space above. The Luma did not lie; they never did. Hailing directly towards the open field below was a long-tailed comet, stuffed to the brim of Star Bits. An abundance of Star Bits was something that the Observatory always retained, but the comet was still a blessing.

Rosalina carefully warned the Lumas to disperse from the area, in order to have the comet crash safely. The Lumas humbly followed the command, and Rosalina watched, with the Star Bits trailing from above reflecting in her uncovered eye. She sat upon an incline of the Terrace, she and her Lumas spectating its arrival.

In mere moments, it did, and thousand of Star Bits piled upon the flora-filled landscape. The Lumas cheered, and Rosalina gave an optimistic grin. The same Luma that informed her of the happening arose and neared Rosalina once again.

“Thank you for getting us out of the way, Mama!” It dazzled and pranced about, ending with a hug to its Mama. “Now that we have all of these Star Bits, what are we going to do?”

Rosalina brushed her hair aside, her second eye briefly being revealed. “My children...this comet is truly a blessing. Enjoy it as much as you’d please, and thank the stars above for their gift.”

The Lumas cheered, and began to dive into the stockpile of Star Bits, lavishing its harvest. The pale Luma that Rosalina conversed with came to the pile, and looked back to its Mama. It held a Star Bit in its hands. “For you, Mama!” the Luma offered to Rosalina. Other Luma looked Rosalina’s way, watching Rosalina’s reaction. Rosalina giggled, and gladly took the Star Bit - it was her favorite treat. The only treat she could get, really, but the taste was worth a thousand universes. Like sweet, sweet honey - with a cosmic, unearthly tinge to it. The aroma of a Star Bit was something like an inherent memory.

Taking a composed bite out of it, she licked her lips, savoring the flavor. Observing Mama’s gleefulness with the gift triggered other Lumas to provide her with more of the blessing - her children crowded towards her, all bearing Star Bits. Rosalina felt overwhelmed, but continued to represent herself as the calm, maternal being that she always was. “Now, now, children, don’t you think this is too much Star Bits for me? I’m not a Hungry Luma,” she noted, the various colors of the Luma and the Star Bits gleamed in her eyes.

“B-but...Mama…” a now depressed yellow Luma moped. Instantly, Rosalina’s feeling were flipped - she could never bare to see one of her children so saddened. “...I’ll eat as much as I can, okay? Star Bits are very tasty,” she eased her children. They all cheered with their fruit from the comet, dancing together. In their elation, they encroached Rosalina’s personal bubble a bit too close. Rosalina wanted them to wait their turn, but their constant, echoing cries of “me, me!” made Rosalina indulge in the peer pressure. She simply picked who was closest and tenderly enjoyed the Star Bit, the taste of honey becoming ever more apparent to her taste buds.

Rosalina tried to coax her way out of the Lumas from feeding her, but to no avail. After the hype from the Star Bit comet landing on the Terrace died down, Rosalina walked slowly with her painfully stuffed stomach back to the Library, of where she would rest by the comforting flame of the hearth. Plopping her behind onto the chair, she finally felt relief - sometimes, even a cosmic deity needed some alone time. She loved her children above all else, but the discomfort was apparent in her midsection. Through her dress, she could feel her stomach protruding from its thin and trim state - stuffed to the brim with the sweet Star Bits. Breathing deeply, inward and outward, her diaphragm pushed itself outward, making her belly even more bloated than it already was.

Just then, disturbing the peace and quiet the Library provided, was a Luma carrying a Star Bit. Rosalina shifted her chair aside, and was ready to say “no,” but the arced eyes of the Luma representing happiness was too much of a persuading force. “For you, Mama!” Rosalina took the Star Bit once again, and ate it happily in front of the Luma. Her belly groaned in its discomfort, but she kept pressing on, rubbing it to quiet its dismay. “Thank you, Luma,” she told it, after her Star Bit was finished.

“Such innocence,” Rosalina happily thought, once again...

Two months passed since the landing of the Star Bit comet - or, what Rosalina presumed, anyway. In the Observatory, there was no way of measuring time. Life resumed to its careless nature, and Rosalina continued to overview the Luma ecosystem, and took care of them and the Observatory itself. What hadn’t faded, however, was the present overabundance of Star Bits on the Observatory - they landed constantly, after the Star Bit comet landed. Rosalina could admit, that even some of the Lumas did fattened up themselves - some even turning into Hungry Lumas and begging desperately for the sweet trickle of the dew inside a Star Bit.

The chair in the library creaked intensively, as Rosalina still rocked in her sky blue dress. The gifts of Star Bits proved to be a caloric challenge to Rosalina’s once limber body - her unsheathed neck lost its definition a while ago, and her face began to relish in newfound roundness. Cloaked underneath her gown was a body who began to shed its nondescript nature, Rosalina’s belly now pressing against its cosmic fabric. Her breasts, while once lacking in magnitude, began to blossom with flab, now increased in size. Underneath Rosalina’s belly were thighs that had just touched a few days ago - an intriguing sensation by the submissive woman. At the root of them was a buttocks now, while possessing firmness, stuck out a tad under her clothing.

The newfound interest sparked some Lumas to create finer delicacies out of Star Bits - formulating a smoothie like substance out of the otherworldly treat. This is what arose the boom in Hungry Lumas - and in Mama Rosalina’s size, as self-proclaimed “chef” Lumas showed their inventions to her.

Eating was no longer as stressful as a task as it once was deemed - if she were to be as stuffed with as much Star Bits as she was when the comet crashed, it would no longer be taxing on her stomach. It expanded with all the treats the Lumas provided her; making filling her stomach with the honey-tasting treat a breeze.

Rosalina had scheduled a story time with her children, sitting eagerly in the chair, her thicker arms centered in her lap. The bickering of Lumas was heard as they approached the Library, all resting upon the ground. Provided with each of them was a Star Bit - something that Rosalina was bound to accept.

To counteract the chaotic nature of Lumas, she instilled discipline in the method of providing her with presents. In an orderly line, they all gave Rosalina a Star Bit - she took them by her side, offering a pleasant snack whenever she would read literature alonde. Once they were all piled in a corner, Rosalina couldn’t resist having some of them for herself as she prepared for the story. Standing upwards, she maneuvered her fattened body over to the stockpile, collecting some in front of her children. Some Lumas danced about, happy that their Mama plucked their provision of the pile of Star Bits.

Once she came back to rest upon the chair, a final creak in the chair emerged and it turned into a pile of wooden detritus upon the ground, Rosalina falling into it. “Ah!” she cried, her belly jiggling once she landed upon the carpeted floor. The Lumas gasped - they worried for their Mama’s safety. “Mama is too big for the chair!” one Luma called out. The concept of weight gain was relatively unfamiliar to Lumas, except the Hungry Lumas that travelled about. Rosalina sheepishly blushed - she would have to have a talk with that Luma later. However, all of them wanted to volunteer to get Mama a new, better chair to fit her size.

“My, my, I respect all of your offers,” Rosalina told her children. She knew that further weight gain would be inevitable, and all the chairs the Lumas would get her would be broken eventually. “The floor is fine, here,” she tells them. “I can read to you, my children, just fine…”

The Lumas sacrificed their offer for an extra chair for an offer of more Star Bits. Rosalina was earning her title of cosmic deity.

“Now, chapter one…” Rosalina read, her plumpness resting itself upon the red carpet, heated by the fireplace behind her.

The capitalization on the Star Bit abundance didn’t recede, even after three months slipped by the grasp of time. Lumas were constantly interested on making new sorts of meals and treats out of the cosmic candy, and Rosalina’s waistline continued to suffer. Her children accomplished so much, all because the blessing and overabundance of Star Bits. Lumas were an impressive species - even with her long life span, they never failed to please.

Rosalina arose out of the Bedroom in a baby blue nightgown, the bed giving a withered creak. recalling back to the time where she enjoyed Star Bits on the side - her waistline never suffered. The concept of weight gain was so unfamiliar to her; she then remembered two weeks after the Star Bit comet’s blessing - she glanced in marvel at the new plushness of her stomach, then, confused as ever.

Exiting the violet chamber inside the Bedroom, her body was no longer “chubby,” on the boundaries of “chunky,” she was full on fat. As she hung on the rim of the bed, astonished with how much she let herself go and how quickly it took - stationed underneath her breasts, of which burgeoning into two flabby, yet perky balloons upon Rosalina’s chest, was a belly of two rolls, and a deeply concave belly button stationed in between their crease. Rosalina embarrassingly caressed the belly, flustered with its sheer size. It made her leisurely gait suffer, transforming it into an uneasy waddle. Her thighs spread themselves to the width of the belly, even when pressed together. Each of her buttcheeks were the size of a Luma, a tender rub of them sparking the thought. A new chin sprouted upon Rosalina’s face, with a layer beneath it becoming softer by the day.

Even through all this hardship with her body, her eye was still covered by a curl of hair, and a silver crown was adorned on her head. She came into the closet, finding the dress she wore daily. “Lumas! I need your help,” she yelled, out the curtained entrance of the Bedroom. Two sparkly yellow Lumas came to Rosalina’s aid, and picked the dress from the closet. “Look away for a moment,” she told them, and undressed herself from the nightgown, with nothing but a pair of panties, with the same sky blue motif as the rest of her wear.. She could never get used to the site of her fattened body, bare by the lack of vanity. “Put on the bra, please,” she calmly asked of the Lumas.

Being nearly naked, even with the company of non-human Lumas, was still uncomfortable to Rosalina. The pair of Lumas floated underneath Rosalina’s fattened arms, applying the bra to her breasts and hooking it from the back. She turned herself aside, and with some difficulty, fit into her dress. Due to her weight, the cosmic dress did not meet the floor, revealing Rosalina’s calves and feet, of which were equipped with light blue high heels. Even with her weight, she still kept a calm elegance to her maneuvers. “Thank you, my children,” she thanked to the Lumas, as they drifted outside with a happy cheer.

Welcoming outer space with a step outside, she noticed a basket of Star Bits was stationed by the room. “This will be my breakfast,” she figured, plucking the basket outward and wondering about the Observatory. Lumas greeted the plumper Rosalina with the same childish pip that they always had, and it never failed to etch a smile on Rosalina’s face. One Luma came up to her and offered their Mama some of the pure concentrate from a Star Bit, of which she humbly obliged. The offerings never stopped as she calmly circumnavigated the Comet Observatory. Once tired from her walk (much easier now due to her weight) she plopped upon the surface, gazing briefly at the celestial bodies above, and snacked upon her Star Bit related provisions.

“Heavenly,” she commented, her belly giving a subtle groan in response to sampling one.

It was a year since the Star Bit comet crashed onto the Comet Observatory, bringing further abundance of Star Bits to Rosalina and her Lumas - especially Rosalina herself. Rosalina was fortunate, as holding her possession wrought mystical powers that would make life easier. Realizing that, at her weight (she estimated she was quadruple her original size) she could utilize her ability to levitate to good use. No longer would she need to be bound to the floor and challenged with her weight - rather, she could continue to grow and move around at the same time.

With the knowledge, she continued to do so - plumping herself up with the Star Bit gifts and specializing some of her children to bring her aid when confronted with a problem with her size. Rather than beat around the block with it, she allowed her children to play with it as much as they’d like - seeing Rosalina’s flab was a wonderful sight. Rosalina made a personal decision, considering her and her Lumas’ independency, no longer would she have need for clothing, striping it off one day and revealing her fattened body to her children.

She positioned herself right in the middle of the Terrace - her naked and fat body would be comforted by the flora below her, instilling a calmness. Her hair was well-kept by the Lumas she politely asked to do so, and considering their submissiveness to their Mama, they humbly obliged.

Her belly divided itself into many rolls, and even separate “bellies” - first, they were allocated by the belly button. Then, when leaning down, they transformed into rolls, a favorite part of Rosalina’s body the Lumas loved to fondle. She counted three rolls - or, her Lumas did, because seeing the front of her belly was an impossibility. Her feet were long obscured by the massive behemoth her belly had become - some Lumas rumored that there was a black hole in there.

Hungry Lumas, inspired by Rosalina’s weight gain, arose about to become their own galaxies once hugely bloated - huge and diverse the galaxies were, all due to their immense bloatings. Rosalina, curious about the life of a Hungry Luma, decided to enact an experiment with her Lumas.

“Please, Luma, could you gather a surplus of Star Bits?” she kindly ask, assuring her lady-like status. Collecting the thousands they kept in storage, Rosalina opened her mouth, her obese vessel plopped upon an incline - it was deja vu to the original landing of the Star Bit comet. They counted down, and Rosalina made her mouth agape - underneath it were a few chins, of what she considered “gifts from the Star Bits themselves.”

The Star Bits came so hastily, but Rosalina gave a elegant confidence as she ate them all, keeping her esophagus open so they slipped right through. It mere moments did the Star Bits show their mark on her belly, rapidly expanding itself. It came to her knees in terms of its sheer size, and continued to burgeon itself outward with the sweet treats.

About ten thousand Star Bits in total were estimated to fit inside Rosalina’s belly once the Star Bit shooting process was done, and Rosalina marveled in how much her belly could hold. The Lumas, eager to please, begged Rosalina to have something to wash it down with - which was a fresh glass of the concoction of Star Bits. Some Lumas went ahead and rubbed themselves onto the tender belly of Rosalina’s, like the fireplace in the Library. Some fondled it, as well, desperate to give comfort to their Mama.

The digestion would take awhile, but the Lumas’ Mama was delighted to envisage the progress she would be making the next day. One day, the feeling of having a belly with limitless capacity came to Rosalina, like a dream, and her weight gain accelerated. Some Lumas were busy at work one expanding the several domes on the Comet Observatory, wanting to make sure their growing mother could fit inside each.

As Rosalina stroked her groaning stomach, she gave a speech to her Lumas. “Lumas, I must thank you all for offering me many gifts along the way to make Mama large. I do it for you, my children, because you love it so...I must also thank the Stars above, for the blessing they have provided me and my children.”

Rosalina gazed to the stars above - they seemed beautiful as ever.
