The Most Corpulent Centaur

Centorea "Cerea" Shianus had been in love with her Master, Kimihito, for as long as she could possibly remember at this point. Even though she had had to contend for his affections with multiple other women over and over, again and again, she had never considered on giving up on him. She wanted to do everything that she possibly could to obtain his love. However, it was not until a few months ago that Cerea had come to discover a very interesting fact about Kimihito. A little secret of his that, if she utilized it correctly like she intended, she would not only be able to win his heart, but possibly be able to keep it forever as well. The centaur's whole body was somewhat large and awkward simply because she took up so much space being herself; the lower horse half of her body was the main culprit to this fact. Her breasts were nearly as big as her own head, another aspect of herself that seemed to be considered too big for its own good. However, she'd never thought about how much she could use this largeness to her own benefit. Not just her breasts either, but very single part of her body, as it turned out, was good for something. Especially her stomach.

"Huff...puff...mmh...huff...ah...puff..."

Cerea had only managed to find out about this secret of Kimihito's primarily by an accident. She had entered his bedroom while he was away with Papi one morning under the pretense of wanting to help clean. Of course, she did her best to get some actual cleaning done, including wiping down the windows and brushing off dust from the counter-tops, but really she was in his private quarters for the sake of gathering information. She wished to learn as much about her Master as she possibly could. It was the best way for her to be able to appeal to him, after all. If she fulfilled each one of his desires for the perfect woman, he was bound to accept her as his beloved. Cerea could hardly contain herself as she peered through every nook and cranny for evidence. Anything at all would do. She knew much about Kimihito already, but there were still many things, many private things, that she didn't know about him either. Cerea scanned over his bookshelves, she glanced into his underwear drawer (with one hand over her eyes, peeking through the cracks of her fingers) and she had even checked out what sort of toiletries he most often purchased too.

That was when she had the idea to inspect underneath her Master's bed. Not the most original place to conceal one's private goods, but then again, she had looked everywhere else but underneath the mattress so far. What she managed to find were mostly dust bunnies and balls of lint, but there were some magazines that she had not seen before too. Cerea reached underneath and took one of them out. They were wrapped in plastic so that the dust would not contaminate it. Cerea frowned. None of the other books were like this at all. She tore away the wrapping and discovered a woman of curvaceous figure presenting herself in a provocative pose. The centaur's ears folded back against her head and her cheeks began to glow brightly with embarrassment. It was not all that surprising that her Master would own books like these, as he was still a young man. However, she felt somewhat insulted, even if that was not the intent, that he would keep books like these around when he had someone like herself living with him in his house.

Cerea flipped through the pages of the book to see what sort of women it displayed inside. The woman on the front cover, wearing a set of cute pink lingerie, was actually more heavyset than the typical Japanese female. Cerea hadn't thought much of it at first, but now, after inspecting the contents, she came to understand why that happened to be. The women featured in the magazine were very large. Ranging from chunky to chubby and beyond, these were clearly women who weighed much more than most. Cerea's jaw dropped. She placed the magazine aside and grabbed two more of them. They too also displayed plump women on the front; one of them smiling as she sat sunbathing and another covering her perky breasts with a thin towel. There were nothing but fatties to be found on every single page. Some of them weren't human, like a chubby harpy and a plump lamia. There was even a 'cow-grade' centaur woman posing in nothing but a set of overalls on the opposite cover of one of the magazines. Cerea couldn't believe it. She'd just learned that Kimihito, her Master, apparently liked fat women most of all.

"Huff...URP...puff...oof...huff...ooh...ugh..."

How her Master obtained the magazines, she didn't know. She had suspected that he either had them mailed to him directly or he went out and bought them at the very dead of night. So that was his fetish. He was interested in women of size. Heavy women. Large women. Obese women. Fatties. The word to describe them didn't really matter, because in the end they all meant the same exact thing. Kimihito was a chubby chaser. Cerea could not believe that she had never figured it out beforehand. He showed no real romantic interest in any of them over another. In fact, he seemed adamant in avoiding such matters. It could possibly have been because none of the women living in his household were fat enough to fulfill his specific tastes. Incredible. Simply incredible. Cerea was amazed by this discovery, but at the same time, once she'd calmed down enough to think about it, she was actually grateful. To become fat would be a simple matter. If she'd become big enough, then Kimihito would not be able to ignore her anymore. She may have had to go from being a horse to becoming an elephant, but if it meant his gaze would be fixated solely on her, then she had become willing to do it.

Cerea wasted no time in beginning her quest to become the fattest woman in the household. It wouldn't be the hardest thing for her to accomplish, given that everyone else were so thin, but that did not mean that Cerea would not take her new mission seriously. In fact, she intended to take it very serious, to become as fat as she could conceivably become. She'd chosen from the very beginning to never tell any of the others about her discovery. She got along well enough with some of the other girls, but in the end they were still her rivals, which meant that she needed to cherish and withhold any advantage she could possibly get from them. Cerea went out right that very day and bought as much candy, chips, soda and other fattening snacks she could think of. It eventually led into what was her first of many future binges to come.

Cerea ate and ate and ate all throughout those first few days. Of course, she wasn't very used to it at first. Her stomach constantly hurt whenever she finished off a huge meal. It hurt so bad that it nearly made her want to give up the idea of gaining right then and there. However, she was determined to win Kimihito's heart at that time. Even though her growing belly felt like it could have popped, she still managed to force another eclair, another piece of tofu, another slice of mushroom and spinach pizza through her trembling lips. To be able to truly gain the serious amount of weight that she needed, Cerea had to forego her typical healthy eating habits, the dietary needs of a centaur as large as herself, and eat as if she were more like a hog than anything else. Instead of salad and yogurt she would eat sandwiches and pasta. Instead of water she would drink soda and other types of soft drinks. Cerea spent more time lying around reading than she normally did so that the food could digest and make her body grow. The other girls might have wondered what was going on with her, but Cerea didn't worry about their opinions. She only cared about getting her Master to finally notice her for who she was.

When she'd developed a potbelly for the first time, it had left Cerea with a mixture of competing emotions. She was horrified, at least for several seconds, that she had let herself go and had blown up to growing this big. However, this was exactly what she had wanted to happen to her in the first place, so part of her was actually thrilled that her gaining plan was working out so well. From that day forward, she had begun pushing herself more and more. She wanted to gain even faster. She increased her meal portions, took more naps in between said meals, and she always, ALWAYS asked for dessert after dinner. The changes quickly became apparent to her as she came to terms that it wouldn't only be her stomach growing, either. Her face grew thicker, her chin started to double, her arms even became fleshier especially around the biceps. Her breasts, of course, kept growing bigger. Even Cerea's horse half of her body seemed like it was taking on some of the weight too. A centaur was not supposed to gain much weight due to how it could seriously affect their sense of balance. However, Cerea was not too afraid for whatever side-effects could come from her pursuit for love. She had already decided she would be willing to face any challenge as she became even fatter.

Cerea was undeniably dedicated to her mission. Her need to be big enough for Kimihito coincided with an increasing appetite. It did not take long before she started to eat for the sake of her hunger rather than just trying to fatten up. Of course, turning into a gluttonous pig helped Cerea gain faster. Her belly grew outward and then began to dip lower and lower until it was forced to split itself into separate rolls. Her face's thickness proceeded onward with cheeks as puffy and squishy as marshmallows and multiple chins that coated her neck. Her centaur legs grew flabby too; they still had some muscle hidden deep inside to be able to carry her enormous girth, but that was concealed by mounds upon mounds of blubbery, droopy fat. An entire couch could nearly be swallowed whole by her backside alone. This all happened to Cerea in a matter of months since she had started traveling down this one-way path to obesity.

"Oof...hah...hah...hah...almost there...mmph..."

Now, over a year later, in present time, Cerea believed she had finally achieved the size she'd been pining for all along. She had just left the bathroom only a few minutes ago. After stepping onto the industrial-sized scale to inspect her weight, the morbidly obese centaur had been given a pleasant surprise. She had reached a true milestone in her gain. She had already weighed quite a lot more than the other girls and this was before she'd ever intentionally packed on weight. That was almost entirely because she was a centaur, so she had more 'mass' than most women to begin with. However, as of today, she had grown past a whole quarter-ton. She had put on over 200 pounds on her human upper half alone. Not a single one of those extra pounds was anything else but pure fat. She decided it was time to finally pronounce her love. No more hiding. She wanted her Master to know exactly how she felt.

Cerea entered the living room where she found Kimihito watching television, all alone just as the centaur wanted him. Cerea smiled, although her grin might have looked lopsided due to how badly out of shape she was. A simple walk from the bathroom into the living room had left her without much breath to be found in her lungs, but then again, it was probably to be expected. She was strong, very strong, but she still wasn't strong enough to carry all of this extra weight on her body day in and day out. However, it was a minor trouble, hardly anything that she ever found to be an inconvenience bad enough to change her ways. It was not like she could possibly do anything to change herself, anyway. Her gluttonous impulses were completely out of control by this point. She could eat and eat and eat all she wanted, but fullness was not something she could simply obtain anymore. Even when she did it lasted oh so fleetingly; she was always left wanting to snack on something less than an hour after the fact. Cerea inhaled through both a gaping mouth and flared nostrils as she slowly approached the couch.

"Master...I...I have come bearing good news for you..."

Kimihito looked away from the television to see the full breadth of Cerea's enormity before him. There was no mistaking the sudden sensation of tightness within the center of his pants, but he didn't say a single word as Cerea drew even closer. Her multiple chins were shining brilliantly under a exuberant coating of sweat.

"I've finally reached it, Master. I have reached the exact weight that you had wanted from me. I'm large enough to be a bed for you now!"

Kimihito smiled awkwardly, his blush giving away how excited and anxious he felt. "You really do look just as big as one, huh?"

"I'm so large, Master," Cerea slipped a pair of hands underneath her belly and tried to lift it. The huge sack of blubber was such a struggle to hold up. So much of it spilled everywhere around her. Her skin was so slick and wet with perspiration, she couldn't even manage to get a proper grasp on any of her rolls. "I'm so large and fat and...ooh, I need to sit down..."

Kimihito scooted over so that she could rest her weary legs beside him. Cerea let out a sigh of relief upon laying her backside into the soft, bending couch cushions. When Kimihito had initially found out that Cerea had gotten so fat specifically for his pleasure, he'd felt guilty at first. It made sense that he would. He hadn't thought that it was fair for Cerea to dispel her own health and well-being for the sake of some strange fetish. Of all of the things he could have been into, of all the different types of women and monster-women that inhabited the same planet as him, he had to be most into the fat ones. Maybe that was the reason he'd never been able to pick any of the numerous monster girls that had come to inhabit his abode.

Cerea pressed herself up against him. Her breasts partially swallowed his head and her stomach rolls oozed over onto his chest and lap. She was simply enormous. Her plump lips puckered up as a faint coo escaped them. She leaned in even closer. The morbidly obese centaur gave off such an aura of warmth, that not only would she make a wonderful bed but she would be especially great to cuddle up against when winter rolled around.

That was when Cerea suddenly noticed that there were candies sitting on the table, so of course, she had to grab a few for herself. However, she didn't get very far before she began tiring herself out again. She let out a few tiny grunts, her whole face lighting up once more, but sadly for her, her bloated upper-limb didn't have the reach that it used to. Kimihito gladly took a handful of sweets and passed them over to her. Cerea opened her mouth but she did not take them by hand. She wanted Kimihito to feed them to her instead, one by one. Her huge belly growled loudly. She'd hit a new milestone in her weight gaining quest but it likely would not be long before she made it past another one. She crossed her front legs together while at the same time her heart began to race, but the latter wasn't because of exhaustion. She had never known how exciting it would be to be hand-fed like this by the man she adored so much.

At the same time, Rachnera was spying the pair closely through the nearest window, hanging upside down with her webbing to better exhibit stealth. She didn't quite know what to think. She never thought she would see the day that Cerea would not only throw away all semblances of her physical health to become this bloated, flabby butterball of a woman, but that Kimihito would actually LIKE it as well. it frustrated her. She'd known all about those magazines for a long time, longer than any of the others. She'd been into his room multiple times without him knowing, after all. However, she'd never had the courage to go so far as to gain weight for him. It didn't seem sensible to her that the young man would find her more attractive if she gave up her figure rather than retaining her gorgeous looks. She didn't think she'd need to do something like that. Yet that was apparently the key to winning over his heart all along.

Rachnera rolled herself back to the rooftop. She needed to start rethinking her plans about this. Or she might just have to give up entirely. It wasn't as if she would ever be able to gain enough weight to reach the size that Cerea had obtained.

Or could she?
