I was going to heavy edit this section before I put it in the anthology but never got around to it when I dropped the story. Hope this part is okay...

Sarah felt her growth accelerate over the next few weeks and new strength came hand in hand. She put away the money she received from teaching ballet for the gear and new outfits. When she walked by Mark in her first one, a fitted tank and leggings that accentuated her growing muscles, he only grunted a noncommittal response. His eyes remained glued to the TV.
Later that day, while attempting to open a jar of pickles, Mark let out a frustrated groan. Sarah, with a nonchalant shrug, effortlessly twisted the lid off, the metal cap popping with a satisfying snap. “Looks like I loosened it,” he managed somewhat unconvincingly.
“Yeah, that’s probably it,” she responded. Mark looked up at her and saw something different. There was an aura about her.
“Babe, you’re looking good. Maybe we should have sex or something tonight.”
“Maybe, there’s always a first,” she responded.
“Don’t talk shit to me,” he yelled. Sarah ignored him and walked out the door. Just like the previous months, there would be no sex that night, but more and more often she was releasing her own steam. Her sex drive, long since dormant, was well - on steroids and she couldn’t get enough of it but Mark still paid her no heed.
Sarah didn’t need him. After a long workout, she’d inevitably come home sweaty and slick and surrender to the intoxicating sensation of her own touch. Dropping onto the bed before her shower the need enveloped her. Her body had become a vessel for the purest form of ecstasy. The gentle caress of her fingertips against her warm, wet slit elicited moans of pleasure from her lips. It was always a quick episode of self indulgence though because her greatest joy was the gym.
She’d been getting to the gym earlier, devouring protein, and focusing on building strength. At the gym, every rep, every set, was a defiance against Mark’s dominance. Soon enough, taut muscles replaced soft curves.
At first, the changes were subtle. There was a slight increase in muscle definition here and her recovery increased. She was never sore after workouts anymore. It was as if her body wanted more work.
As the days turned into weeks, Sarah's metamorphosis accelerated with breathtaking speed. Her t-shirts, once loose and flowing, now strained against her broadening shoulders and thickening biceps. One morning, Mark reached for the milk carton from the fridge, only to find Sarah's hand already there. Her grip was firm. He tugged, surprised by the resistance. “Woah, there, tigress,” he chuckled, a nervous tremor in his voice. Sarah simply raised an eyebrow and passed him the carton.
Day in and day out, Sarah reveled in her growth and particularly her increased strength. Chiseled definition replaced soft curves and her skinny up and down frame became a hulking V-tapered shape. Shoulders broadened, arms became riddled with striations, and her legs became thick… really thick.
She flexed her quadriceps, and a satisfied grin stretched across her face. Beneath the tight skin, the muscles pulsed with a life of their own. They simply bulged with raw strength and the thickness resembled the columns of granite beheld on Greek temples. The sweep of her hamstrings and the sinewy lines could be seen even through the fabric of her tights. Squatting with the barbell she was now doing effortlessly would have crippled her a few months ago. Her muscles craved more weight -- more challenges -- more growth.
Heads swiveled as she walked by, whispers erupting in her wake. Even the seasoned female bodybuilders couldn't help but steal a second look. As she moved over to the dumbbells and sat doing an endless drop set of concentration curls a man nearby blurted out nervously, "those are some serious arms!" Her arms now featured veins snaking across her biceps and triceps ragged rivers and their bluish-green tendrils pulsed with every contraction. With each curl of the dumbbell, the sinews beneath her skin danced a hypnotic jig. Finally, she dropped the weights with a thud. Raising her arms into a mighty flex, the muscles welled up into a colossal peak, striated with veins that resembled miniature lightning bolts pulsing beneath the taut skin. Even the deltoids capping her shoulders dwarfed the heads of most men in the gym. Dense and powerful she knew that she was now skirting the boundaries of what most considered feminine, but she still wanted more. It was once solely about strength but had become a complete transformation that pushed the very definition of what a woman could be. From ballet dancer to bodybuilder...
A sly grin stretched across her face. Soon, Mark will find out. And the thought, once a flicker of defiance, now burned with an intensity that mirrored the power coursing through her veins. The prospect sent a surge of anticipation through her. It was going to be fun, indeed. But more importantly, it was going to be a day of reckoning.
