Sally grabbed the bag and snatched a handful of patches. Quickly, she reached under the seat and slid the chair back as far as it would go - she would need the space. With trembling hands, she pinched one patch and pulled down the neckline of her t-shirt. She slapped the patch on her chest above her breasts. Her back straightened immediately as her torso clenched all at once. Through the gripping tension, Sally slapped another over her shoulder onto her back. She whimpered as the sensual vice in her muscles gripped even tighter. She snorted fierce, carnal breaths, and slapped another on her abs. Her heart pounded harder than she thought possible. She slapped two more on both thighs.
All her muscles clenched and flexed and erupted with blinding pleasure. Her body generated a brutal burst of torque that twisted her from side from to side. Her muscles creaked outwards in relentless pulses. She was quickly soaked in sweat. The unstoppable pleasure pounded relentlessly. Her physique juddered bigger and bigger. Her muscles pounded in every part of her body. She felt her shorts tightening, electric power and pleasure struck up and down her legs. She watched them bulging outwards under the steering wheel. Her slender thighs ripened with thick, brawny trunks.
Two thick plates of muscles groaned out of her chest. Her breasts lowered under a merciless wall of expanding pectorals. Inch after inch poured out, she felt her body hungrily sucking on the patches. Her t-shirt grew tighter and tighter as it pinched around her swelling torso. A second later, her hips started to buck uncontrollably. White hot pleasure roared in her midriff. Sally growled as a pair of brick-sized abs punched out of her stomach. Followed by two more, before a final pair creaked outwards to complete her blocky six pack.
She tried to straighten her pounding, expanding thighs. Her quads were ripened with endless layers of twisting, swollen muscle. She watched them bulge and press into each other. She pointed her toe and watched a medallion calf muscle jerk out the back of her leg. Veins zigzagged down both legs. This was before she noticed her head brushing the ceiling of the car. Her back stretched wider in keen spasms. Sweat poured down her nose as her muscles squeezed her in their passionate, expanding embrace. Sally moaned as her body inflated into a heavyweight bodybuilder in moments.
Finally, her pulse seemed to stamp with less ferocity. The arresting spasms and muscle-twitches subsided, and the numbness in her jacked-up body gave way to boundless, intoxicating power.
Sally looked down at her hulked up body. Her t-shirt was almost suffocating. Her nipples were about the pierce that taut fabric across her juicy pecs. Her chest was a now a shelf-like ridge of muscle that almost blocked her view of her tiny shorts, which now resembled the hot-pants the girl her boyfriend had taken into his car was wearing. She wiped the sweat from her eyes with her brawny forearms. Unbelievable power crackled through every fibre of her.
"I'll show them." she purred, and heaved her enormous new body out of the car.
