The matriarch of the Klaus household had a few choice words to say when Katarina and her brother Keith had returned for summer break. In the six months that Katarina had been at college she had swelled to an unbelievable size, so much so that her mother had hardly recognized her when she returned home. After subsequently fainting, picking herself up off the floor and fainting one again, their mother had decreed that Keith was to be put in charge of managing his sister’s diet from this point onwards with only the household’s best intentions held in mind.
Such a solemn duty was something Keith was firmly accustomed to. Although they were not bound by blood, and being younger than his boisterous and scatterbrained elder sister, he doted on her nonetheless. Having their mother’s blessing in this way felt more like he was being integrated into the family which gave him all the more reason to spend time with his favourite person.
After a stern lecture which seemed to last for hours, Katarina and Keith walked through the doors leading out to the forest of the estate’s sizable acreage and life was wonderful once more.
“It’s not that noticeable, right? I mean, come on, who doesn’t gain a little weight in their first year of college?”
Keith only nodded and kept his mouth shut. Through the many years they had spent growing up together, he had watched his elder sister’s rabbid appetite and lust for food run its course over her figure. Her metabolism started to slow after her 18th year, rendering her a vision of beauty at nearly 500 pounds at 5’4’’. He marvelled at the magnificence of engineering which was her bra as their family wealth had spared no expense to make her custom fit clothing, holding up nearly a foot of cleavage above an enormous drooping waistline. Katarina’s womanly hips were accentuated further by her curve hugging dress which clung to the silhouette of her belly. Her self-reassuring complaints drowned themselves out against the sea of new fat which jiggled with every step she took.
“...don’t you agree, Keith?”
Katarina’s voice echoed in his ears
“Keith?”
“Oh, um, yes sister,” Keith nodded humbly. “It’s perfectly normal.”
Katarina beamed. Her simple mind was so easily reassured, most likely because of her simple heart. It was one of her most appealing features, but also the one which Keith had to be aware of as her natural magnetism drew more and more rivals for his affection for her. In truth, watching her fatten up had been something which he was banking on using to dissuade others who were not used to growing up with someone who ate almost around the clock since childhood, but an abundance of new curves only seemed to get her more noticed. It was only fair after all, since she was a natural beauty at any shape or size.
“I wish mother wouldn’t lecture so much,” Katarina sighed as they stopped near a large tree. “We almost missed lunch, because of it.”
Katarina smiled a devious leer as she reached into a hollow cut into the tree to retrieve a picnic basket worth of sweets. Keith had predicted the likely outcome of their return home and had prepared for such an eventuality with a message to the household’s head maid in secret. This wasn’t the first time Katarina had ALMOST been sent to bed without a meal for the myriad of disruptions she had caused in her youth.
“Good work, Keith! I knew you wouldn’t let me down!”
“Naturally, dear sister. I’m always thinking about your wellbeing.”
Lunch that day was especially delicious, with all of Katarina’s favourites blended into a delightful five course spread. Three was her normal go to, but riding around in the carriage really worked up her appetite as did moving about at her new, great size. She began by soaking a strawberry in dark chocolate and heavy cream before saving each bite, washing it down with one of the house wines. Each bite was followed by an almost audible murmur of pleasure as Katarina closed her eyes to swallow. It was only as the last bite disappeared, she noticed that Keith had been silent throughout her feasting.
“You're awfully quiet,” Katarina prompted. “Is everything okay?”
“Oh, it’s nothing, dear sister,” Keith replied “Just thinking a little.”
In the game world she was familiar with, Katarina had read Keith Klaus’ thoughts like a book. Where his real world self was meek and soft spoken, the game world version she was familiar with was a woeful womanizer with an insatiable appetite for girls of every kind. Guys were after all, natural horndogs and she couldn’t really help with that.
“Ah, you’ve got a special sweetheart on your mind, don't you!” Katarina said in a shaky, but reassuring voice. “It's nice to think about them from time to time, but there’s more to life than just that.”
“T-time for what, exactly,” Keith said shakily, unaware how to manage such stimulation.
Katarina, trying to hold back her own embarrassment, held his hand reassuringly and pressed her chubby fingers deep into his as she unwittingly pulled him against her belly’s softness.
“You know...SEX,” Katarina said in a whisper shout. “You’ve got to make sure you really love a woman before you-”
Keith immediately withdrew his hand from hers. Hand over foot, he scrambled backwards several feet as he attempted to distance himself from his beloved sister.
“But-I-Um-that is-I mean I love you...as my sister...and...but mother…”
The panic was almost palpable in his voice as Katarina moved closer. She had assumed that reaction had meant she had hit the nail square on the head and now was the time for action. Their father had never had ‘the talk’ with her little brother as he was far too busy, so it would fall to her to repay his diligent kindness.
“Come here, Keith,” Katarina beckoned with an embarrassed whisper. “I’m going to teach you how to become an adult.”
“O-oh dear god...it’s finally happening…,” Keith spluttered. “I need to get my heart ready first…”
With some effort, Katarina heaved herself to her feet. Her leather boots planted themselves firmly into the ground, causing her body to wobble as she cast her colossal shadow over her brother.
“Okay...so...the first thing you have to do is....” Katarina began breathily, already puffed from the exertion of standing. “Is...um…”
She felt her face turning redder, adding embarrassment to her exhaustion. After several minutes of awkward mumbling from both parties, Katarina had her next brilliant idea.
“Actually, why don’t you use your earth magic to make a few dolls and we can practice.”
Keith blinked.
“Come again?”
“You know...so that we can both watch and I can give you pointers…I am your big sister, after all.”
While the two of them did have the ability to magically channel the element of earth to their whims, only Keith possessed the raw talent to carve golems out of stone which he could puppeteer to his will. Katarina’s much less impressive ‘earth bump’ allowed her to make a single small trip hazard which was far less suitable for the display she had in mind.
“Okay, so summon one and show me how you’d try to win me over. Give me your best shot.”
Unaware of how to approach this strange request, Keith merely did as he was told. A small stone humanoid erupted from the ground in front of them, dusted itself off and bowed before its master. With adept fingers, he directed the little creation over to another one of the hollowed out trees and brought forth yet another of the many snacks he had stashed away in the event of his sister’s next bout of hunger pangs. It trotted over to Katarina who marveled in adoration of the little automaton.
“Aww, thanks little guy! This one’s my favourite!”
Keith smiled. He felt himself relax a little. He was never really good with women, in spite of what his sister thought of him, but he knew how to approach her from a variety of angles. Those angles only seemed to increase as she grew ever wider with the passing days.
Katarina dug into the little dessert she was brought, pressing her hand to her plush cheek as she chewed and swallowed. Her rapture towards all things edible was only interrupted by a little tug on the side of her skirt as another clay golem vied for her attention.
“Oh! You too huh? Well, I guess that’s okay,” said Katarina kindly. She gave her brother a worried look. “I hope that this isn’t meant to represent you approaching another girl at the same time, Keith.”
Dutifully, she took up the next treat and ate it too. Nothing made Keith happier than watching that smile on her face and knowing full well how to put it there.
As Keith’s thoughts and feelings began to trickle through, so too did they manifest into more magical creatures. Each one was a memory, bound to a location where he had stashed more and more food for his beloved sister, each one powered by his affection. It wasn’t long before an entire army of eager golems had returned and began to crowd around the object of his desire. Each one was awaiting the opportunity to pay homage to her immense girth in hopes of having more of her to go around.
“K-keith,” Katarina gasped suddenly, overwhelmed by the deluge of treats and clay admirers. “Okay, I think we can stop now. You’re going to make your future love very fat if you’re this aggressive.”
Keith only smiled. Where he had once feared his magic going out of control as a youth, he had learned that the golems disappeared of their own accord once their initial task had been fulfilled. Katarina knew this too, steeling herself for the onslaught of new snacks which she would have to eat.
“My future love...I wonder just how fat she’ll become before this day is through…”
