Rachel pt 2

She pushed 275lbs at the bench press, grunting loudly, and racked the weight with a bang. She jumped up off the bench, breathing heavily, and thumped her fist against her thick pecs. Her breasts, which had been respectable C cups, looked small, pushed out and down by her growing pecs. It was like her thick pecs were eating them. She grinned, enjoying that thought. Soft tits were weak - she urged her pec muscles to feed on them tod get bigger, thicker, and harder.

“Not bad,” Dave said as he came over and checked the weight bench. “For a girl.”

Rachel stood and faced Dave, going toe to toe with him. Dave was a head taller, and he was stacked with muscular bulk. Rachel had gotten big, but Dave was still bigger.

He snickered down at her. “You’ve got a ways to go before you get to this level,” he said, flexing up a huge bicep. 

Rachel gritted her teeth. “You smug bastard, I’m going to even the odds and out-muscle you!”

David chuckled. “Not until you grow a set of these,” he said, cupping his ball sack. He wore tight workout shorts and she could see his huge nut sack stretching the fabric. He was a genetic freak, she knew, with more testosterone in his body than two normal men. Rachel frowned as David turned and walked away.

That’s when Rachel decided to get really freaky. She upped her dosage again, pushing the limits. Her body responded. In fact, the more she pushed, the more it responded, absorbing mutant-level amounts of testosterone that might not be good for another human. But somehow her body thrived on it.

She blew up, gaining dozens of pounds of muscle in six weeks. She had started this journey as a 5’6” 150lb woman, and now she tipped the scales at 220lbs of butch beef. Staring in her bedroom mirror, topless, she flexed her phone-book sized pecs. They rippled with striations and veins as she grit her teeth and grunted. Her nipples pointed straight down as her bulky pecs jutted out. Her breasts were gone - eaten alive - by her monster pecs. 

She relaxed her chest and flexed her abdominals, which bulged with apple-sized blocks feathered with striations. Her thick obliques jutted out from her waist, giving her a thick, blocky appearance. She smiled, flexing her thighs. They bloated up, hanging over her knee by inches. Her calves were so big she could see the muscles bulging out and to the sides without turning.

She smile madly as she looked at her mid-section. She wore tight white boy-briefs. Thick black hair crawled from under them, above the waist and below her crotch, barely contained. It looked like she had shoved a sock under there.

But she hadn’t. No, she had finally done it - just what Dave had suggested. She laughed, a deep, throaty chuckle, as she flexed into a most muscular pose. Veins rose from her abdominals and thighs, inflating to pencil-sized worms. It looked like a road map of squirming worms, pulsing ominously and feeding into her crotch. The fabric of her briefs stretched as her traps rose and her lats inflated. Her pecs and biceps bulged, fighting for space as she crunched down harder.

She watched as her briefs stretched tighter, the waist band pulling away from her thick abdominal wall. She groaned, feeling the briefs start to tear. With a giant thrust, she bucked her hips, and the briefs tore off and fell. A thick, raging erection bobbed up, and a bulbous nut sack bounced as she licked her lips. She reached down and grasped it, feeling electric shocks through her body. She stroked it, slowly at first, then faster as she watched the sweat drip down her rippling pecs and abs. She bit her lip, bucking her hips as she stroked faster. Her other hand felt her hard glutes, her thick abs, and reached up to squeeze a bulging pec. She moaned.

“Oh fuck, so big!” she cried, stroking faster. “More!” she cried, imagining herself growing even bigger. Thicker pecs, jutting out, bigger traps swallowing her head, bigger arms, like cantaloupes. And a bigger cock.

Big enough to dominate Dave, that little shit at the gym. Bigger than his dick, twice as big. And bigger balls, a huge fucking nutsack, pumping her with man hormones and pushing her muscles bigger, harder, thicker. She’d shove her big dick down his throat. She’d fill his mouth with her nut sack, suffocate him with it.

“FUCK YES!” she cried, “BIGGER!”

She bucked and came, spraying her mirror with her spunk. Panting, she licked her lips. “And I’m just getting started!”
