Just as his finger squeezed the trigger, the door crashed open as Katie came back in. "Forgot to get that gun from you..." she started before bumping into Arnold.
As the ray gun went off, it's shot went wild and instead of hitting Amanda, it ricocheted off his dresser mirror and hit Katie square in the chest.
"What the hell!?" she screeched as she suddenly started to grow taller. As her muscularity rapidly dwindled until she was back at her normal physique, she crowded the room until she topped out at 10 feet tall, having to drop to all fours to keep from hitting her head.
"Arnold, you twerp!" Katie reached out and grabbed him by the throat, easily wrapping her entire hand around his neck. "You give me back my muscle or I'll... owww! Ow! Ow! Ow!"
The oversize girl started howling as Amanda, unseen by the giantess, had jumped on top of Katie's head and started tapping the girl lightly.
"Or you'll do WHAT!?" she boomed.
Katie squealed as she pawed her hair trying to dislodge the mighty mite, only to have her finger grabbed and twisted by Amanda.
Jumping to the ground, Amanda forced Katie onto her face by easily continuing to wrench her finger.
Looking up at Arnold, she growled "Let's try this again, shall we? Only this time, make sure the muscle growth setting is up."
She let go of Katie's finger and moved towards him as Katie clutched her finger in agony.
Arnold swallowed hard and, after re-adjusting the muscle growth control, pointed the gun at Amanda only to jump in surprise as Angela and Evie burst through the doorway.
They looked in surprise at Katie who pointed a swollen and crooked finger at Amanda. "Stomp on that little bitch!" she screamed.
Angela looked down and as she immediately stomped on the tiny figure, she was shocked to feel her foot hit what felt like an iron spike. And then she gasped as she was suddenly tossed across the room, crashing into the far wall, stunned.
Evie looked confusedly at Angela and then back at the floor where
Amanda stood defiantly, her super powered muscles bulging with
fantastic strength.
Peering closer a shocked look crossed her features. "Amanda? Is that you? How'd you get so small?"
Amanda scowled up at her. "That jerk Arnold shrunk me down to keep me as his pet. Only thing, he hit me with the same ray he used on all of you. I swear I'm gonna kill the next person who keeps me from getting bigger, so don't even think about it!" Turning back to the boy, "Well, get on with it!"
Just as Arnold was about to pull the trigger, Amanda saw him look quickly behind her. Turning abruptly, she saw Katie swinging a huge hammer down on her head. Calmly reaching up, she stopped the hammer so abruptly that Katie was forced to drop it from her hands.
Amanda sighed as she then spread out her arms around the head of the tool and slowly started to pull it against her chest.
The hardened steel didn't have a chance and screeched in protest as it was forced against breasts ten thousand times harder.
As everyone watched in stunned and awed fascination, Amanda completed her feat of super strength by shearing the head completely in half.
Arnold couldn't help himself as he shot his load and keeled over backwards, dropping the gun, while Katie seethed in open jealousy, and Evie rubbed her crotch with unabashed lust.
Her task completed, Amanda stared hard at Katie. "Try anything else and YOUR head is next!" The girl just scowled but slowly backed away.
Turning to see the passed out figure of Arnold on the floor, she looked up at Evie and eyed her carefully.
"Like that, did you?" Evie nodded, speechless, her heart racing as she continued to stroke herself.
"I can give you more than just a show..." she started sexily, not quite sure if she could trust the muscle girl or not. "All you have to do is point and shoot..."
"Don't do it!" Katie suddenly spoke up. "She's lying, she just wants all the power for herself!"
Amanda growled and hurled what was left of the hammer towards Katie embedding it into the wall inches from her head. "Shut up, you!"
Turning back to the muscular lass she pleaded, "C'mon Evie, we used to be friends. I can see you still care for me and I certainly don't want to stay a two-inch tall, super-sprite forever."
Evie looked at the gun and picked it up. Holding it in her hand she...
