The "Alphabet Run" was the gold standard of speed swellers, women who would push their gifts of growth to the limits and get as big as fast as they can. While a sub-90 second time to add 26 inches to their bust line has long been theorized and planned by the community, it has only been recently that someone has pulled it off.
Devon squared up against Alyssa, alcohol still strong on both their breaths. Lightning arced between their gaze, but neither of them blinked.
"I'm so fucking sick of hearing this! So what if I'm already a G cup! That doesn't fucking mean anything!" Devon stuck out her chest, pressing her breasts against Alyssa's As. "I can still compete! I can kick your ass any day of the fucking week!"
Alyssa's eyes narrowed, her lips twisting into a haughty smirk. "Listen, freshman. I've been doing this a lot longer than you have. No one naturally bigger than a C cup has ever placed competitively. Breast, ass, or any other category! And don't say Cooper Bering. You know as well as I do the only reason she placed is because the entirety of the Green City Growers was disqualified because they got caught using Prolactidine. And she still only got third!" She poked a single finger into the side of Devon's squished tit, the younger competitor trying to keep her fierce composure. "The point is, you used up all your growth potential, G Cup. You don't belong in this sport."
Embarrassment burned in Devon's cheeks and ears, her mind sputtering as she tried to figure out how to retort. The warmth only grew as her teammates stared at her, some with pity, some hoping she'd put Alyssa 'The Ass' (a nickname she earned not just for her primary event) LaRue in her place. Devon took a deep breath, holding it until she finally blurted out-
"Fuck you! I'll do an Under-90 Alphabet Run! Then maybe you'll finally shut the fuck up!"
Hushed whispers spread through the crowd. Alyssa took a second to register what Devon had said. When she did, she couldn't help a laugh. "You? The alphabet run? Yeah, and if you flap your arms hard enough, maybe you can make a cow fly!" Alyssa took a step back, slapping Devon's tit from underneath, making her yelp. "Fine, G Cup. You're on. You do an AR90, something no one has ever done successfully, even at a professional level, and I'll leave you alone. Hell, I'll make a public apology! But if you don't..." Alyssa's face took on a sinister expression. "Then you take your tits and get the fuck out of my sport. Forever."
The thought of giving up competitive growing, the sport she loved, made Devon pause, but she was too far gone. The die had been cast. She stood up straight and nodded her head. The crowd went wild.
The crowd was going wild, cheering Devon on as she raced through cup sizes. Even though she started at G, it was tradition for Alphabet Run attempts to be counted by observers by letter for every inch grown. The run ended at Z, but many people didn't make it that far.
Alyssa was sweating. She tried to keep her focus on the stopwatch in her hands, but she couldn't keep her eyes off of Devon. The sheer size and heft of her breasts was nothing short of a miracle. Even without the seven cup head start, they were a sight to behold. Each one had to be bigger than both Devon's and her own heads combined!
And they were still growing!
Alyssa swallowed. "Y-you'll never make it! You still have five cup sizes and only... Five seconds!"
Concentration twisted Devon's face. Her chest heaved. A deep breath rushed into her lungs and-
The crowd stopped counting, simply staring in awe as Devon's breasts surged in size. They looked more like they were inflating than growing. Devon arched har back, trying to push every last ounce of growth that she could into her tits. By the time they stopped, six full inches had been added to her already gargantuan bust. There was a half-second of awed silence before a ringing broke the trance.
The crowd erupted, rushing in on Devon to celebrate her victory. The now exceedingly top-heavy woman staggered, suddenly feeling the weight of her enormous breasts sticking out more than a foot in front of her.
Alyssa just stood there with her jaw dropped open. Her whole worldview had been shattered. She should have been embarrassed at the loss but all she could think was Holy shit... We're gonna win every fucking trophy...
