Jill smiled as she heard the button click when pressed into Josh's nose. She could hear his muffled protests, no doubt trying desperately to record something to stop her. However, the tape held Josh's mouth firmly shut, and she pulled the Dictaphone away from him to ensure his efforts would be in vain.
Jill recognized that she couldn't keep the Dictaphone away from her brother forever. Furthermore, the moment he did get it back he'd erase the recordings on it, and be far more thorough in securing it from being used by anyone else.
There were a few ways she could handle the problem, but to her the most appealing way was to make the magical device irrelevant.
"I have the Dictaphone's powers, and this change can't be undone in any way!" she recorded.
Josh's eyes widened with terror. He tried to turn his head away from the buxom beauty his sister had become, but Jill soon managed to get his nose to meet the stop button.
The siblings were quickly overwhelmed by the intense sparkling sound coming from the Dictaphone. It was all Jill could do to not surrender to the most incredible sensation she'd felt in her entire life. Immeasurable power flooded into every cell of her body, along with visions of seemingly infinite possibilities.
She saw worlds where Josh and Kevin turned themselves into hot girls. Worlds where Vanessa Barnes had received the Dictaphone, losing it in several of those yet managing to claim it for herself in others. Even worlds where she didn't recognize anyone, filled with technology both ancient and highly advanced. All of these and more flashed before her eyes in less time than it took to blink.
Just as Jill was about to wonder if she'd be driven mad by it all, the sparkling and visions at last abated. She felt powerful beyond measure... but not physically so. She reached over towards Josh, and ignoring his attempt to recoil from her hand, tore the tape off his mouth. "What the fuck did you do?!" he yelled. "That thing is dangerous! It's not a toy! I can't believe you'd be so-"
Josh's tirade was cut short as Jill glared at him. Her clothes, severely undersized and stretched to their limit as they were, began tearing at the seams as she grew before his very eyes. Her legs stretched longer, sending her head ever closer to the ceiling. Her far too small pink shorts gave way to her generous hips and huge, mouth-watering ass, the latter grazed by long, silky brown hair cascading down her back.
His attention drawn by a sudden loud rip of fabric, Josh beheld his sister's swelling breasts burst free from the confinement of their prison. With contemptuous ease, Jill tore off the remains of her shirt, standing proud in her naked glory while her brother remained transfixed upon her massive melons. For the moment, her knowing smirk was completely lost on him.
It was only after Josh came harder than he ever had before that he noticed Jill had stopped growing. The 8'4" tall amazon in front of him was recognizable as his sister, but any physical trace of her being the younger sibling was far gone. He couldn't imagine a hotter 20 year old woman's face. Her skin was entirely free of acne and blemishes.
Jill's ass and hips were certainly impressive, but easily her best and most prominent feature was her breasts. Josh was certain she'd long outgrown JJ cups, but continued to wear them so he'd be teased with the mystery of how big she actually was. Each massive, gravity-defying teardrop shaped globe was topped by rock hard nipples the size of bottle caps that begged for attention.
"So, what did I do, my little brother?" she said, her voice a sensual purr that made Josh instantly hard. "Well, you know what I recorded, but I suppose I'll explain the rest. Who knew fixing things could feel, mm, so good?"
Josh was freed from his sister's bindings, only to be set upon her now too small bed. She was upon him almost immediately, earning a groan from him and the bed as she sat on his pelvis. Instinctively, he tried to push her off, but her hands redirected his to her tits. "This... this is wrong, Jill..." he wheezed feebly.
"Aw, in a position any man would kill for, and my widdle brother thinks it's wrong. Adorable," she mocked, reveling in the slight shudder of Josh climaxing to her again. "That's what makes this so much fun. You are hopelessly infatuated with me. I fill your every erotic desire. You know I can fulfill nearly all of them. But this is the closest you can ever get to the biggest, sexiest girl in the world because she's your younger sister."
Jill bent down, coincidentally mashing her breasts upon Josh's chest. She grinned as she heard his heart pound like a jackhammer. "Everyone knows I can do whatever I please, but we know it goes further than that. You secretly enjoy it when I dominate you like this. You'll keep the Dictaphone safe for me. You dare not use it without my permission, as if you please me like a puppy seeks to please its master, I... may waive the whole us being siblings thing." she said, her whispers like honey to her brother's ears.
She gave him a tender kiss on the cheek before sitting back up. "And that, my dear brother, is virtually your entire reason for existence. You can still pine for Kate, but you know if you get her in bed you will scream my name when you climax," she shrugged. "Who knows how she'll react?"
Josh blinked. A part of him knew this was all Jill's doing and that he should be furious, but also knew it was pointless to even try to fight back. She was a solid 370 lbs of busty amazon with definite hints of muscle, while his thumb muscles were the only ones to see regular use. She could throw him around like a rag doll if she wanted.
More than that, Josh knew Jill was right. He'd never admit it, but his sister dominating him was hot. He was simultaneously frustrated and pleased to be little more than her toy to do with as she saw fit, and strove to please her so that she might one day consider waiving the fact they're brother and sister. The promise of this reward alone was enough to ensure he'd never consider using the Dictaphone without her direct say-so, though she's more than capable of changing reality to her whims without it.
Their parents knew nothing of this, of course. They knew their daughter had certain... needs that came with the weird condition that caused her to grow, but believed Josh only helped sate Jill's needs out of sibling obligation. "Our little secret," as Jill called it.
Finally, the fog of desire lifted from Josh's brain enough for him to think of something other than his sister. "Er, what... what about your friends? Are they still your friends? And if Kevin was human once, then what about him?"
The question caught Jill off guard for a moment. Naturally, her friends still had Kevin in their possession, but she didn't know if they were still friends in a timeline where she'd grown so deliciously huge.
A part of her wanted to forget about the girls. She's more than just the only real woman in a world of petty little children, she's a fucking goddess! And while she didn't need Kevin, she should reclaim him to keep his powers away from would-be rivals. After all, they couldn't wait to steal him from her as soon as she seemed big enough to stop Josh from bothering them...
Much of that was undeniably true, but she still saw them as friends. And they'd never grow bigger than Barnes by Monday. They'd surely fight over him for who got to enjoy the greatest benefit, and that wasn't considering anyone trying to replicate what she did.
And there was something about the dream last night. Kevin had no will of his own, but maybe his powers had a greater affect on her than it would on the others. He did seem to favor her, after all...
"Unlike Barnes, I actually value my friends," Jill answered. "As for Kevin... I'll think about his fate. My friends and I no longer necessarily need his help now, do we?
"But now... I think I will have some brunch. All of this growing is enough to make a girl positively starved!"
As Jill ducked through the doorway on her way out, Josh recalled that his sister's voice always sounded like a honeyed invitation for mind-blowing sex rather than a mere act for anyone's benefit. A far cry from her original, almost whiny tone that did little to encourage anyone to listen to her, as now everyone gladly clung to her every word.
Suddenly, the strained bed came to life and carried Josh to the door before roughly tossing him out of Jill's room. "No offense, brother, but I'd like you out of there for now," he heard from downstairs. "Might I suggest a cold shower and a change of clothes before your jizz-stained boxers get too uncomfortable?"
