Georgia wrote a sentence. Butternut's muscles grow by 50% and become stronger by 100% every time she flexes. She hit enter and turned around to face the maid.
"Would you flex for me, Butternut?" she asked.
The wolf-girl squeaked, jumping at the request. "Are you sure, Mistress? You know what-"
"Yes, I am sure, Butternut," Georgia interjected. "Now just flex for me."
Timidly, the maid lifted her arms in a double bicep pose and flexed. Georgia watched as they bulged out more than they should have, and noticed how her maid uniform was growing tighter as she did so. Her stomach had been sucked inwards, with grooves showing as her slight tone became far more chiselled. Her thighs thickened, and even her tail seemed bushier.
Georgia raised an eyebrow. "Again."
Butternut dutifully flexed again, groaning a little as her clothes began to constrict her large pecs and obliques. She dropped her hands to her sides. "Is that good, Mistress?"
"No," Georgia decided. "Flex again."
This time, there was a sound of ripping as her uniform finally started to give way at the seams, showing off a glimpse of strong muscle tucked beneath the fabric and fur. Georgia smiled. "Can you lift my bed, yet?"
Butternut grimaced, then nodded as she easily picked up the bed with one hand and lofted it above her head. She tossed it from hand to hand like it weighed nothing at all, then put it down carefully. Georgia's eyes widened.
At her surprise, Butternut stepped in to explain. "You said you know what happens when I flex, but I fear you don't. Each time, the effect compounds on the last, so it first doubles my strength, then quadruples it, etc. I am currently 8 times stronger than I was before, and have-" she thought for a second, "337.5% more muscle than I did previously."
Georgia gaped. "So, can you punch a hole through the wall?"
"Of course, Mistress, did you not just hear me?" She walked over to the wall and calmly plunged her fist through. The chunk of wall flew out and landed in her pool. "I am superhuman, now, Mistress, or rather, super lupine. You may not grasp it, but I can do most any impossible task you set me."
Georgia smiled tightly. "Good. But I don't care about that at the moment. Flex again," she ordered, and so Butternut had to obey. Her thick musculature began to bulge off her frame as she flexed her biceps. But Georgia showed no signs of stopping.
"Again!"
"Again!"
"Again!"
The word was repeated nearly 15 times before she finally was satisfied, though nearly crushed against the wall from the sheer size of Butternut's hulking, monstrously muscular body.
Now standing at a massive 15 feet tall, Butternut's shy exterior and dainty frame had been replaced by a behemoth of pure muscle. Her pecs alone would be the size of waterbeds, and ripples with each heaving breath. Her tree trunk arms were stuck to her sides, pinned by the walls of the tiny room. Her legs, each easily three times the thickness of Georgia's body, were thick with veins, protruding even from beneath her now short, coarse coat. Behind her ridiculously small spectacles, Butternut glowered at her mistress, her lip curling into a fanged sneer.
"Do you realise what you have done?" she rumbled. Her voice was far lower than before, a dark, aggressive, dominant growl. "Do you have any clue what the fuck you just did?"
Georgia, too awestruck to speak, shook her head.
Butternut gave out a growl of frustration, her jowls snapping together irritably. "You know how I said I was 8 times stronger before? Take a guess how powerful I am now."
She didn't even have to flick a finger. Just the slightest twitch of her body, just the blink of her eye, and the entire house was thrown outwards, obliterated by her pure strength. The wolf held onto Georgia tight, moving even quicker than her own shockwave to encase her mistress in her massive paws, her indestructible muscle a perfect shield. In the rubble of the house, Butternut stood up and held her mistress in her outstretched palm with a titanium grip.
"My strength was once just 800% Now, thanks to you, I have over 131, 000 times the strength of any other being on Earth." She leant her large, wolfish muzzle down close to Georgia's face. "I can survive a nuclear war. I could survive the death of the universe. I could obliterate you and everyone on this planet with nothing but a clap of my hands. You have made a god, Mistress, do you understand?"
"W-what are you going to do with y-your power, Butternut?" Georgia stammered out nervously. The predatory look Butternut had, her intense, intimidating appearance made her instincts scream to run from the monster, but she could feel her arm encased by Butternut's thumb and forefinger, and knew it would be trivially easy to snap should she move.
The same thought had gone through the maid's mind several times, and she paused, mulling it over, before sighing and placing Georgia down on the ground. "Nothing. I'm not going to do anything with it. I'll control the power and use it only to serve you best, Mistress. After all, I was put upon this Earth only to fulfil your every desire. Should you wish for me to continue growing, for me to become larger and stronger, I will have no choice but to obey. But please, Mistress, allow me to stop now. You have a god of strength at your service, what more could you want?"
