Fat Camp

Caleb drummed his fingers impatiently on the kitchen counter, frequently checking the time on his phone. His parents had texted an hour ago saying they were "almost home" with Raelynn, but the driveway remained empty. He wasn't particularly excited to see his sister after three months—they'd never been especially close—but the curiosity was killing him.

"What kind of fat camp actually works?" he muttered to himself, adjusting his glasses.

He'd seen the brochures lying around before Raelynn left. "Total Transformation Camp for Young Women" was plastered across the top in bold letters, with before-and-after photos that looked as fake as those diet pill adverts on late-night telly. His parents had spent a small fortune sending his sister there for the summer, and Caleb couldn't help but feel a twinge of resentment. Nobody had ever spent that kind of money on him.

The distant sound of tyres on gravel interrupted his thoughts. Caleb glanced out the window and saw his parents' car pulling into the driveway. His father got out first, followed by his mother from the passenger side. They both seemed to be smiling oddly as they moved toward the boot of the car.

"That's weird," Caleb muttered, squinting through his glasses. "Where's Raelynn?"

As if in answer to his question, the back door of the car swung open. Caleb's jaw literally dropped as a figure emerged that he barely recognised as his sister.

"What the bloody hell...?"

The woman—it couldn't possibly be Raelynn—unfolded herself from the car in a way that seemed to defy the laws of physics. She just kept... rising. Where his pudgy little sister had once been, there now stood what could only be described as an Amazon. She towered over their parents, her curly black hair pulled back in a ponytail that swung between her shoulder blades as she stretched with casual ease.

Caleb staggered back from the window, blinking rapidly behind his glasses. That couldn't be right. He must be seeing things.

The front door opened, and his mother's voice called out, "Caleb? Come help with the bags, would you?"

On wooden legs, Caleb made his way to the entrance hall just as the front door swung wider to reveal the full magnitude of what had happened to his sister.

Raelynn ducked—actually ducked—to enter the house. She was wearing a white t-shirt with 'Fat Camp' printed across the chest, the same oversized XXL shirt she'd left in. Except now, instead of stretching around her middle, it strained across her shoulders and chest, riding up to reveal a strip of toned midriff. The sleeves that once hung loose now clung to defined arms.

"Hey, nerd," she said with a familiar smirk, though the voice came from much higher up than he remembered.

Caleb stared up—actually up—at his younger sister. At 5'9", he wasn't short by any means, but Raelynn now seemed to be at least a head taller than him.

"What... how..." he stammered, his brain failing to process what he was seeing.

"Take a picture, it'll last longer," Raelynn said, dropping her duffel bag at his feet with a heavy thud. "And while you're at it, bring that upstairs for me."

Their mother chuckled from behind her. "Be nice to your brother, Rae. He's still processing."

"What did they feed you at that camp?" Caleb finally managed, finding his voice.

Raelynn just smiled mysteriously. "Proper nutrition and intensive training. It's amazing what the body can do with the right programme." She flexed an arm casually, the motion causing the sleeve of her t-shirt to ride up further, revealing a bicep that would make gym enthusiasts jealous.

"But that's—that's not possible," Caleb sputtered. "Nobody grows that much in three months!"

"Tell that to her wardrobe," their father chimed in, struggling through the door with several shopping bags. "We had to stop for clothes on the way home. Nothing fits her anymore."

Caleb couldn't tear his eyes away from his transformed sister. It wasn't just her height, though that was shocking enough. It was the way she carried herself—with a confidence that bordered on swagger—and the obvious strength in her frame. Raelynn had always been the chubby, awkward one. The one he could always feel superior to, even when everything else in his life felt mediocre.

Now she looked like she could bench press him without breaking a sweat.

"This is a joke, right?" Caleb looked around desperately. "You're all having me on."

Raelynn rolled her eyes. "Still the same old Caleb. Can't handle not being the centre of attention?" She reached over—way over—and ruffled his hair condescendingly, like he was a small child. "Don't worry, I'm still your little sister. Just... not so little anymore."

Caleb swatted her hand away, his face burning with embarrassment. "Whatever. I've got work to do." He turned to head back to his room, but his mother's voice stopped him.

"Actually, Caleb, dinner's almost ready. I put a lasagne in before we left to pick up Raelynn. Why don't you help set the table?"

With a resigned sigh, Caleb changed course toward the kitchen, painfully aware of Raelynn's tall figure shadowing him as she followed.

"So what have you been up to all summer, short stuff?" she asked, reaching past him to open a cabinet that he usually needed a step stool to access.

"Working," he said shortly. "Some of us have actual responsibilities."

"Oh, I worked plenty," Raelynn replied, setting plates on the counter with ease. "Six hours of training a day, plus nutrition classes and all sorts of workshops. That place was no holiday camp, I can tell you that much."

Caleb snorted. "Right. And I'm sure the results are completely natural too."

Raelynn's smile faltered slightly. "What's that supposed to mean?"

"Come on, Rae. People don't just grow half a metre and put on that much muscle in three months. What were they really giving you there? Some kind of steroids?"

For a moment, something like hurt flashed in his sister's eyes, but it was quickly replaced by a hardness that was entirely new.

"You always were a sore loser, Caleb," she said quietly. "Can't stand the idea that I might succeed at something, can you?"

Before he could respond, their mother bustled into the kitchen with a bottle of wine. "Let's celebrate Raelynn's homecoming with a proper family dinner! It's been too long since we've all sat around the table together."

Dinner was an awkward affair, at least for Caleb. His parents couldn't stop marvelling at Raelynn's transformation, asking endless questions about the camp's regimen and philosophy. Raelynn, for her part, seemed to be enjoying the attention, though she remained vague about exactly how the camp had achieved such dramatic results.

"The director said some of it's proprietary information," she explained through a mouthful of lasagne—her third helping. "But it's all natural, just very... targeted. They customise everything to your specific body chemistry."

"Well, the results speak for themselves," their father said approvingly. "You look incredible, sweetheart. Healthy and strong."

"I feel incredible," Raelynn agreed, flexing her hand around her fork. "It's like I'm finally comfortable in my own skin, you know?"

Caleb stabbed at his pasta, appetite diminished. "Looks like you're wearing someone else's skin entirely," he muttered.

"What was that, dear?" his mother asked.

"Nothing," he said, forcing a smile. "Just thinking about work tomorrow."

After dinner, as Caleb was loading the dishwasher, Raelynn approached him with a gleam in her eye that made him instantly wary.

"Remember how you used to always challenge me to arm wrestling when we were kids?" she asked, leaning against the counter beside him.

Caleb tensed. "Vaguely."

"You never let me forget that you were stronger, even though you were skinnier than a rake," she continued, a grin spreading across her face. "Always saying 'muscles beat fat any day, Rae-Rae.'"

"We were kids," Caleb said dismissively, though his heart was beginning to race. He could see where this was heading.

"How about a rematch?" Raelynn suggested, exactly as he'd feared. "For old times' sake?"

"I'm busy," he said, turning back to the dishes.

"Come on, Caleb," their father chimed in from his seat at the table, where he was finishing his wine. "Humour your sister. She just got home."

"Yes, come on, Caleb," Raelynn echoed, her voice dripping with false sweetness. "Unless you're scared?"

That did it. Pride overrode Caleb's common sense. "Fine. One match, then I've got work to do."

Their mother cleared a space at the kitchen table as Raelynn sat down, rolling up the sleeve of her t-shirt to expose an arm corded with muscle that definitely hadn't been there three months ago. Caleb took the seat opposite her, trying to appear nonchalant even as his stomach knotted with dread.

"Just like old times," Raelynn said, placing her elbow on the table and extending her hand.

Caleb gripped her hand, immediately struck by how much larger it was than his own. Her fingers wrapped completely around his palm, and he could feel the calluses that hadn't been there before.

"Ready?" their father asked, clearly enjoying the spectacle. "Three, two, one... go!"

Caleb immediately pushed with all his might, trying to catch Raelynn off guard with a quick start. Her arm didn't budge. Not even a centimetre. Instead, she sat there with an amused smile, as if he weren't exerting any pressure at all.

"Is that all you've got?" she taunted quietly, so only he could hear.

Gritting his teeth, Caleb pushed harder, his face reddening with the effort. Sweat beaded on his forehead as he strained every muscle in his arm and shoulder. Raelynn's arm remained perfectly vertical, immovable as stone.

"Come on, Caleb, I know you're not even trying," she said with mock encouragement. "Put your back into it!"

Fueled by frustration, Caleb threw his whole body into the effort, half rising from his chair. For a brief, hopeful moment, he thought he felt Raelynn's arm give slightly—but then he realised she was deliberately allowing him to gain a few centimetres, only to hold him there effortlessly.

She was toying with him.

"That's a bit better," she said, as if praising a child. Then, without warning, she began to slowly push his arm back toward the table.

Caleb resisted with everything he had, his entire body trembling with the effort, but it was like trying to stop a hydraulic press. Inch by inexorable inch, Raelynn forced his arm down, her expression barely changing save for a slight quirk of her eyebrow.

"Not fair," he gasped. "You're... you're using your weight."

"Actually," she said calmly, "I'm using about ten percent of my strength right now. But I can stop, if you want it to be over quicker."

Before he could respond, she lowered his hand to within an inch of the table surface, then held it there, demonstrating her complete control over the situation.

"Should I let you try with both hands?" she offered, and the genuine lack of malice in her voice somehow made it worse. She wasn't being cruel; she genuinely thought he needed the handicap.

"No," Caleb said through gritted teeth, "just finish it."

With a small nod, Raelynn pressed his hand flat against the table, ending the match.

"And we have a winner!" their father announced unnecessarily, raising his wine glass in Raelynn's direction.

Caleb pulled his hand away, flexing his fingers to ease the ache from Raelynn's grip. "Congratulations," he said stiffly. "You've proven you can beat your older brother now that you're twice his size. Quite the achievement."

Raelynn's smile faltered. "Don't be like that, Caleb. It's just a game."

"No, it's fine," he insisted, standing up. "I've got work to do anyway." He turned to leave, but Raelynn's voice stopped him.

"Double or nothing?" she offered. "You can use both hands this time."

Caleb turned back slowly, his pride warring with his common sense. He knew he should walk away, but something in her tone—not mockery, but an actual offer to make things more even—made him hesitate.

"Fine," he said at last, returning to his seat. "Both hands against your one."

Raelynn nodded, repositioning her arm on the table. "Whenever you're ready."

This time, Caleb wrapped both hands around her one, bracing himself more strategically and leaning his weight forward. At his father's count, he channelled all his frustration into a determined push.

For a moment—just a moment—he thought he might actually make some progress. Raelynn's arm tilted slightly, perhaps five degrees from vertical. But then it stopped, and despite his doubled efforts, he couldn't gain another inch.

"Not bad," Raelynn conceded. "I actually felt that one."

From the sidelines, their mother chuckled. "My goodness, Rae, what on earth did they feed you at that camp? I'm starting to think I should sign up next summer!"

Raelynn laughed—and in that momentary distraction, Caleb thought he saw his opportunity. He pushed with every ounce of strength he possessed, trying to capitalise on her diverted attention.

Without even looking back at him, Raelynn stopped his advance and slowly, deliberately began pushing back. This time, she didn't draw it out, simply pressing his hands down to the table with smooth, irresistible force.

"Nice try," she said, genuine amusement in her voice. "Points for strategy."

Caleb slumped back in his chair, defeated in every sense of the word. It wasn't just that he'd lost; it was the casual, effortless way she'd dominated him. All those years of being the athletic one, the stronger one—gone in an instant.

"I think I've had enough family bonding for one night," he said, standing up abruptly. "Congratulations on your... transformation, Rae. Very impressive."

As he turned to leave, Raelynn caught his wrist—gently, but with enough firmness that he couldn't easily pull away.

"Hey," she said, her voice softer now. "I'm not trying to show you up, Caleb. I'm just... excited about what I've accomplished. Can't you be a little happy for me?"

For a moment, looking into his sister's familiar eyes—the same dark brown behind the same style of glasses she'd always worn—Caleb felt a twinge of shame. Beyond the muscles and height, this was still Raelynn, the kid sister who used to follow him around and look up to him before teenage awkwardness drove them apart.

"It's a lot to take in," he said finally. "But... yeah, it's impressive. I just need some time to adjust."

Raelynn released his wrist with a nod. "Fair enough. We've got all summer for rematches," she added with a wink.

"In your dreams," he muttered, but there was less heat in it now.

As he headed upstairs to his room, Caleb couldn't help overhearing his mother's voice from the kitchen.

"You know, Dave, I was looking at that camp brochure again. Do you think they take women my age?"

His father's laughter was followed by a thoughtful pause. "Well, it would be nice to finally have someone who can reach the top shelves without a stepladder..."

Caleb closed his bedroom door, cutting off the rest of the conversation. He glanced at his reflection in the mirror—skinny, average-height Caleb with his perpetually messy curly hair and glasses—and tried to imagine himself transformed like Raelynn.

"Fat camp," he muttered, flexing his non-existent bicep with a frown. "What a joke."

He pulled out his laptop, already mentally composing an email to the camp director. Surely they must have a programme for men too. There was no way he was spending another day being literally looked down upon by his little sister.

In the kitchen below, Raelynn helped herself to another serving of lasagne, catching her mother's surprised look.

"What?" she said with a grin. "Maintaining all this takes a lot of fuel."

"I'm just trying to figure out where you're putting it all," her mother replied, eyeing her daughter's toned midsection with something between envy and awe.

Raelynn laughed, the sound filling the kitchen—fuller and more confident than it had ever been before. "Trust me, you don't want to know what we had to eat at camp. This tastes like heaven in comparison."

As she stretched her arms overhead, causing the hem of her t-shirt to rise even further, her father quickly averted his eyes, still not entirely comfortable with his daughter's dramatic new physique.

"Just don't break any of the furniture," he joked weakly. "We weren't exactly planning on accommodating a... well, whatever you are now."

"A work in progress," Raelynn replied with a mysterious smile. "This is just the beginning."

Upstairs, Caleb hit "send" on his enquiry email, then flopped back on his bed with a sigh. Whatever secrets that camp held, he was determined to find out. The summer wasn't over yet, and he refused to spend the rest of it being embarrassed by his not-so-little sister.

Tomorrow, he decided, he would start hitting the gym. And if the camp didn't accept male clients... well, he'd find another way. There had to be an explanation for Raelynn's transformation, and he was going to discover it.

After all, sibling rivalry was a powerful motivator.
