Amanda didn't - couldn't waste her non- existant breath trying to reply - her rapidly expanding arms couldn't yet hold back Beth's insane strength, and she began to feel dizzy and wheezy as her own massive arms continued to be crushed against her chest. Finally as reason began to leave her as oxygene made her panic, she jerked her arms as hard as she could.

It was nothing. Her biceps were nothing compared to Beth's, and she was weak from lack of oxygen, but her arms were locked deep into her core position, giving her the advantages of leverage. It wasn't anywhere near enough to break the lock on her arms, but it was enough for Amanda to take a deep breath, her chest inflating, and her panic turned to giddyness as she felt her chest rise, her breasts now quite visible even from a standing position. She marveled at them for a few moments as her brain began to focus on the hear and now.. she pushed her arms as hard as she could, in a conserted effort to draw in another breath. Both women strained, trembling in exhaustion as Beth's continual effort taxed even her muscles, while Amanda's sinews and bones had nearly been stretched to the breaking point by the abused Beth had already heaved on.

But Amanda didn't have to win - she just needed to provide enough space to breath, and she took in another breath, this one deep, and Amanda began to realize just how strong she was as her entire body seemed to inflate with the breath. Beth groaned in rage, and finally had the idea to wrap her huge legs around Amanda's rapidly expanding abdomen as well - but her impressive arms were still in the way.

Worse - depsite the collosal weight upon Amanda's frame, Beth was suprised to find she was still standing. "No!!! You can't be that strong! I won't let you be as strong as me! Your puny! Puny!" she called, focusing on squeezing Amanda with the strength of the desperate, trying to keep her biceps from expanding, but now the growth alone was enough to overcome her. Beth closed her eyes and squeezed as hard as she could, feeling growing resistance, the muscles beneath hers that she'd been able to crush now firmly resisted her, and increasingly began to feel like steel as her own muscles began to weaken with fatigue.

Beth then heard a smash, followed by an "oops", before she opened her eyes... and found herself clinging to Amanda's massive back, her 8 foot frame not able to entirely surround Amanada's huge body, which now brushed the top of the high basement, even as she hunched over. Beth gasped and plummeted to the ground as Amanda turned around, now with 4 feet of height and god knows how many hundreds of pounds of size on her. She had to be at least 12 feet tall.

She was no more vascular then Beth - the beam seemed to have made her stockier once it had reached a certain level of optimum muscle development, and she couldn't even guess Amanda's weight. Her build was fairly similar to Beth, it was just.. bigger.. much... everywhere. Even Amanda's chest, which Beth had laughed about - one day Robert and her had bet on whether she was an A or a B - had expanded remarkably.

Amanda looked down at Beth and laughed, her chest jiggling as she grabbed Beth one handed and drew her into her chest, held under the wing of her arm.Meanwhile Amanda held the growth gun in her other arm, held extended away from her, out of reach of any potential sudden grab by Beth.

Amanda said to Beth "Oh. I'm sorry, your finished that little hug. Right. Let me return the favor." she said, and drove her bicep into Beth, letting her have a taste of her own medicine for a few moments before she mercifully stopped crushing Beth's spine, and then threw her roughly to the floor, and leveled the gun towards her...
