Amanda quickly fires the gun at herself and pulls hard on the trigger. A shocking bolt of energy crackles around her and power rapidly fills throughout her frame!!

"OH NO YOU DONT!! YOU'RE DEAD, RUNT!!!!" Katie bellowed and charged at Amanda with the strength of a stampede!!! The whole house shook from each step the mighty muscle girl took!! She then clasped her fists and aimed her elbow at Amanda but as soon as she collided with the energy; believe it or not but the supergirl froze in her tracks!!

The energy fused furiously as Katie tried to increase her force to break through!!!

"RRRGRGGRGRGHHHHH!!!!!"

Suddenly, Amanda threw a fast kick that got Katie right in her ripped abs!! This took out all the wind in the girl and she flew back in the air and crashed through the wall where she landed in the back yard!! The whole house shook as Katie laid in a pile of rubble from the now broken wall. Meanwhile, Amanda began to grow huge as more energy fueled her body. From head to toe muscle erupted all over herf body. Her entire upper torso grew big as her arms thickened with muscles. Her pecs inflated and made her ample boobs blossom even more as they grew bigger than coconuts!
Her shoulders bulged insanely as veins made their way through the beef. Her traps got bigger and bigger and they spread throughout her thick neck. Her abs solidified and defined themselves into her big stomach and gave her a very ripped, sexy six-pack with shredded obliques that grew on the sides. Her hips widened and her ass grew bigger and rounder. Getting sexier by the minute as it felt tight against her jeans. Amanda's legs grew so huge that jeans ripped all along the seams and exposed hot, bulging muscle. Her shoes came off and she wiggled her toes and the energy made her calves get rounder and bigger. Soon the cuffs began to split as her calves grew more!!! Back to her upper body, her shirt ripped in many places as her lats widened and her back filled out with huge muscle. Her tits soon came through the front and snapped her bra completely off as they were now as big as basketballs with some really thick pecs that supported them against the force of gravity. Her entire upper body soon ripped her shirt completely off and Amanda basked in her huge glory as her muscles still erupted with muscle. Soon her entire jeans ripped off completely as both of her gargantuan legs shredded right through them with striated beef. Her ass bulged dramatically and ripped what was left of her jeans and soon snapped her thong completely off. So much muscle packed itself on Amanda's frame as she was now nearing Katie's size but she wasn't done growing yet.

It looked like Amanda was being filled up with watermelons all over her body as she continued to grow bigger and bigger. The floor began to creak under the amount of huge mass she was gaining and when she finally did a most muscular pose, the entire floor shook and a crater the size of two large pizzas cracked itself under her big, sexy feet from the force of her contractions. She was now 7'6'' with 385 lbs of solid muscle. The energy finally faded and Amanda breathe heavily as she was completely in awe of what she just endured. Her mighty chest heaves up and down. Pushing her big tits up and down. Amanda couldn't even see her feet now as she was surrounded by huge muscle that filled her upper torso. She then placed a firm hand on her belly and felt very cut and ripped brickhard abs. She then flexed her biceps and was greeting with bowling ball sized balls of steel on both sides of her arms. Her entire upper torso widening from her double bicep pose. Her back rippled and full with valleys of bubbled up sinew.

"Ooooooooohhhhhhh yyyyyyeeeeaaaahhhh!! That little bitch is about to get the ass whooping of her life!!!"

Amanda then saw the gun and quickly hid it under a pillow on the couch. Then she faced the big hole in the wall as she heard a soft rumble that shook the walls.

"AAAAAARRRRRRGGGGGHHHHH!!!! AAAAAMMMMMAAAANNNNNNDDDDAAAAA!!!!!"

Suddenly, the huge form of the muscle bitch Katie jumped into the living room and made a big crater where she landed. The whole room shook as she faced her adversary. She had to do a double take as Amanda placed her hands on her hips and her entire body bulged with gargantuan, feminine, muscular power. Putting to shame even the big muscles on Katie's frame. Katie was dumbfounded as she took all this in but quickly snapped out of it as rage filled her body and made her look even more pumped with thick veins as it fed her muscles. She wanted to make Amanda pay dearly and the fact she had somehow managed to get the gun back and use its power to grow bigger than her really pissed her off.

"Give me back the gun, NNNNNNNNOOOOOOOOOWWWWWW!!! She yelled.

"It's not your gun, you little whore!!!! And if you want it you're gonna have to fight for it!! But seeing as I'm now bigger than you are!! That's pretty much not going to happen for you!!" Amanda said boldly and stood her ground.

Katie was seething with rage now and her muscles were pumped to the max and ready to go. So without much more though, she charged at Amanda again and the whole house shook!!!!
