“Wow, Alex,” Jack said, trying to keep his eyes from popping out of his head. “You really, uh…you really grew up after you left for college!”
He hadn’t seen his childhood friend in years, and he was already kicking himself for being so tongue tied around her, but he couldn’t help it. She was gorgeous. Her breasts were gargantuan, and her tummy and thighs were so big and soft. And her ass…well, all he wanted to do was fall to his knees and kiss that perfect ass. But Alex had always been a scrawny kid. The two of them used to joke that the puberty bus left her at the station as they played in empty fields and snuck out at night to try and crash parties thrown by the more popular kids whose parents were never home.
This girl…no, this woman in front of him, was anything but scrawny. He couldn’t fathom how she had become so…so…BIG!
And it wasn’t just her voluptuousness that was currently driving him crazy…it was the fact that tiny little Alex Storm, the girl he used to pat on the head whenever she would make fun of him simply because he knew it drove her crazy, was now looking down on him, her eyes easily six inches above his own.
“You like?” she asked with a smirk. “I finally boarded the puberty bus and it was the express, Jackie.”
Jack scowled slightly. He hated that nickname. But he had to admit he was more likely to endure it coming from this goddess standing before him. Still, something was bothering him. “Alex,” he began slowly. “How long has it been?”
She scrunched her face up. “Oh, I dunno. Four or five years maybe?”
Was that enough time for all of this growth? He supposed it must have been. But he’d also kept up with her on social media, and he knew that as recently as nine months ago she’d looked just the same. There were no photos of her in her current…state, so he had no idea when these changes had actually occurred.
“Alex, I’m just going to come out and ask it…how in the hell?”
She grinned. He knew that look. “Oh, I have no idea what you’re talking about,” she said, looking much like a cat toying with a mouse.
“Uh-huh,” Jack said wryly. “You’re enormous and you have no idea what I’m talking about.”
Alex punched Jack in the arm, causing him to physically take a couple steps back. Wow. That had actually hurt. Despite how soft her body appeared, she was clearly packing some legitimate muscle and power.
“It’s not nice to call a woman enormous, Jack. Apparently you didn’t learn any manners since I last saw you.”
Still rubbing his arm, Jack rolled his eyes. “Oh, please. Look at you - you’re a giant! All of this…Alex, puberty didn’t do this and I know it.”
She wagged her finger at him and tsk’d him, not unlike a mother scolding a child. “See, that’s where you’re wrong, Jackie. Puberty did cause this…sort of.”
Jack sighed, moving to sit on her sofa. This was a really nice apartment she was living in. He dimly wondered how she could afford it. “Well,” he said, rubbing the back of his neck. “I guess I’d love to hear more about your “sort of” puberty, then, because I’m totally lost.”
Alex shrugged. “I mean, there’s not much to tell. I kind of fell in with this genius smarty pants at college. He was super into me. You’d like him, Jack, he’s a hopeless nerd just like you.”
“Blah blah,” Jack retorted.
“Anyway,” Alex continued, glaring. “We were dating. He was nice. Then I found his porn stash and discovered he was into women the exact fucking opposite of me - curvy and thick and…just big, Jack. Really big.”
Jack’s look softened as he saw how much this had clearly hurt her. “Hey,” he began. “It’s-”
“I was upset at first, but then he started talking about the stuff he was working on. A machine that actually triggers puberty. Or…I guess a sort of artificial puberty. I’m not 100% sure how it works, honestly. All I know is you start out as you, and whenever it’s done doing its thing, you’re just…even more you. Kinda like…enhanced.”
“Wow,” Jack said. If anybody else had told him that story he wouldn’t have believed it, but seeing the new Alex in front of him, there was no denying that what she was saying was the truth. “This guy is going to be a billionaire.”
Alex shrugged again. “I mean, money isn’t everything,” she paused, looking around her spacious and well-furnished apartment and smirking. “Although I guess it is a little useful.”
“So one use of that machine turned you into-”
“No, no, it’s not that big of a miracle,” Alex said, holding up her hands. “I, uh…may have gotten a little carried away, helping him test it. It’s just…” she trailed off.
Alex sighed, her hands running over her body. “It’s just that it feels so good,” she said excitedly. “That’s what I never told him. The size, the increased mass, the growing…it feels amazing. I cum every single time I use that machine. Multiple times.”
His mouth dropped open but no words came out.
Alex stood from her chair, continuing to run her hands over her body. “I’m not going to lie to you, little Jackie,” she said, her face once again a smirk. “I got a little addicted. My boyfriend broke up with me, said I was abusing his pet project. He tried to restrict my access, get me out of there.”
Alex’s cell phone on the coffee table began buzzing. Glancing down, Jack saw a photo of a smiling man in a lab coat and the name “Sweetie Pie” flash. Alex didn’t bother picking it up.
“He was an idiot if he thought I was going to give that machine up,” she continued, happily touching herself. She pulled one side of her little black dress up, just high enough that he could see the start of her panties. His eyes went wide and he could feel himself hardening in his pants even as Alex’s phone once again began buzzing like crazy, this time with text notifications, every one in all caps and featuring the angriest emojis:
“Alex, are you fucking crazy?!”
“You destroyed it!”
“All my research! How high did you turn up the power this time??!”
“It’s dangerous! I don’t even know what it will do!”
“At that dosage, the radiation will seep right into your bones!”
“Alex answer your phone!!!!!”
Jack gaped, looking up at Alex, who was biting her lip and slowly swiveling her hips while staring at him. She moaned, and he could swear she was suddenly surrounded by the faintest sort of glow, just before he saw her head inch a bit higher, her dress tightening all across her body as her breasts bulged out of it even more.
“Jaaacckkiieee,” she giggled in a sing-song voice, and her head rose up a solid foot, causing Jack to begin scrambling backwards with a startled yell, right up the couch’s back, flipping over it and pratfalling onto the floor. Alex laughed, a loud, tinkling noise that seemed to reverberate up his spine. He looked up from behind the couch slowly, eyes wide, and quickly ducked behind it when he saw her head brushing the ceiling.
The reprieve was short lived, as she moved the sofa out of the way with one hand, smiling down at him. “Hi,” she said happily, and Jack tried not to stare directly at her breasts, which had already exploded out of her dress and bra and hung tantalizingly above him. Her panties looked to be next.
“H-hi,” Jack said meekly, slowly trying to scoot back away from his friend.
“Don’t you like this, Jackie?” Alex asked, her eyes menacing. “Doesn’t everybody want me to have a body like this?”
“Oh, s-sure,” Jack said, his teeth chattering in fear as her head finally cracked against the ceiling, raining plaster over all of them. The blow didn’t appear to hurt Alex at all. If anything she looked even more exhilarated by it, and Jack briefly reflected that with these elevated ceilings, she had to be over ten feet tall.
“I’m just giving eeeeverybody what they want,” Jack’s friend said, her voice angry. “Nobody wants scrawny little pre-pubescent looking Alex…they want-”
Suddenly, she experienced another growth spurt, her shoulders widening the hole that her head just made in the ceiling. Light from the second floor came streaming in and Jack heard screams.
Her hips widened as her body pushed taller, her ass a sight to behold as it pushed the remaining living room furniture out of the way before her breasts began pushing into the second story. Jack could already tell her head was pressing against the next ceiling.
More plaster came down and Jack’s brain switched to auto pilot as he scrambled to get out of the building. He turned around only once before leaving Alex’s apartment to see that only her leg up to mid thigh remained in the room. Crashing sounds from above could be heard as he sprinted away.
“HUGE ALEX!” his friend called, her head finally plowing through the roof of the building, causing it to slowly collapse around her.
Jack’s eyes were wide as he saw his best friend suddenly begin fingering herself out in the open, unable to resist how turned on the process had made her. He felt a buzzing in his hand and looked down, startled. He had picked up Alex’s phone before he ran out. Without thinking, he answered.
“Alex??!” a voice screamed in his ear, causing him to move it away. “What the hell have you done?!”
“Alex can’t come to the phone right now,” Jack murmured into the receiver. “She’s, uh…too big.”
“Who is this?” the voice demanded. “Wait…is this Jack? Are you her friend?”
Jack answered in the affirmative, and he sighed. “I’m going to text you directions to my lab. You need to come right now. She did a really shitty job of breaking my machine so I’m almost done fixing it. I may…god, I know I’m going to regret this…I may need your help to stop her.”
Jack shook his head, then realized he couldn’t see the motion. “No way! This is crazy! Why don’t you use the machine yourself??”
He sighed again. “You don’t send the only scientist who knows how to potentially reverse this mess into the…the thick of battle, you moron. Listen, just…get down here while she’s distracted by her masturbating. This machine causes the brain to release a lot of pleasurable chemicals, so I’m certain she’s a little…you know, busy.”
Jack stared at the enormous Alex, reclining on the rubble of her old apartment and hefting one of her gigantic breasts up to her mouth, sucking on the nipple. “I…I don’t know,” he uttered.
“Jack,” the voice said calmly. “I’m making some improvements while I fix this. I’ll have much better control. The only way we’re going to stop this is if you’re at least as big as she is…preferably bigger.”
Jack’s heart skipped a beat and he suddenly imagined looming over Alex, bending her over a building as her enormous ass jiggled against his significantly larger body with every thrust of his mammoth cock into her folds. He pictured her attempting to sit up only to feel his gigantic hand pressing her upper body back down and holding her still so he could continue fucking her with an earth rumbling moan.
“I’ll be there in ten minutes,” he said, and hung up.
