"Well," Britney began, side-eying her son. "We might be strong enough to physically move, but these breasts are still quite cumbersome. You wouldn't have anything to help with that, would you, Max?"
Right. Max nodded his head and began whistling rising tones, the same scale over and over again. Britney and Alison groaned as their bodies began to stretch and grow taller. First, past 7 feet, able to lift their enormous breasts, the size of a small car, off the ground. Max kept whistling, bringing them to 8 feet, 9, and finally 10. The two Amazons looked at each other in amazement.
"Thank you, Max," Alison purred, and grabbed his body. She brought him to her face to kiss him, laughing at how small and light his body now seemed to her. It was like holding a child! Britney snatched her son away and cradled him in her arms.
"Oh, look at you, baby, so sweet and small again!"
Max blushed. "I'm not small, Mom, you're just huge!" He punctuated it with a few more whistles, bringing both to 12 feet tall. Britney laughed.
"I suppose you're right. Looks like I'm twice the size of you, Maxie~" she tittered, and winked at him, placing him down on her breasts. Max clicked his fingers and both Amazons groaned in pleasure as their jiggling jugs grew even larger. Each nipple was as thick as a tree branch, and Max perched on one, swinging his legs. Just the squirming of his ass against her diamond-hard tir made Britney moan in delight.
Then, Max began to clap. He gave the two giantesses a thunderous applause, as they looked down in confusion. Then, their bodies jerked as their asses began to grow at an astonishing rate.
They surpassed beanbags in seconds, then the car-sized tits that adorned their chests. Alison fell back onto the cushions that now balanced her body, feeling the freight-sized flesh jiggle and ripple beneath her weight. Their thighs, too grew thicker and softer, and Max could hear their hips crack as their bodies adjusted to the new, wider stance they would have to take. Max grinned at them and stopped clapping. He slid off his mother's huge breast and fell onto the bed.
The two giantesses were kneading their hands into the soft fat like it was dough, moaning in delight as their fingers sank deep into the flesh. But, with that added fat and their height stretching them out, Max could no longer see the defined muscles that lay underneath. He'd have to remedy that.
He began to blow raspberries again with that same fervor that compelled him before. Hands didn't come away from asses but instead groped them harder as their arms swelled with even more strength. Their muscles grew hyper-dense, floors creaking under their weight. Their thighs once again took on startling definition even as they retained their huge width. Their asses no longer jiggled but bounced with each flex of muscle.
The room grew swelteringly hot, yet Max didn't stop, making his mother and aunt paragon of musculature, things that would make Michaelangelo weep for the sheer beauty and power trapped within them. The goddesses growled as they fondled their massive assets. Britney worked out that her super strength and heightened muscle control had happened to every muscle, including the ones in her vagina, allowing her to crush tanks to dust within her. Allison found that her breasts, too, had become hard and strong, yet she could make them soft and supple with just a thought. Her nipples snapped to attention as
The two superhumans tossed their heads back as raw power flooded through their veins. Each one was stronger than any superhero could have ever imagined, with extreme control over each and every one of their muscle fibers. Their bodies were grotesque, feminine mountains. Everything was denser than lead, than tungsten, indestructible and indomitable. With a single flex, they'd be able to create shockwaves enough to make cracks in concrete. But Max didn't stop.
Britney's feet began to lift off the ground. She hovered in mid-air. Max's eyes widened. He wasn't supposed to be able to give them literal superpowers, but it seemed that once the body couldn't take any more strength, it had to find other ways to obey his commands. Fire flickered across their skins, hot enough to melt steel, yet they controlled it with ease. Allison's moves became a blur as they gained super speed, and their minds matched with reaction times beyond what any animal could dream of. Their eyes began to glow, as the two goddesses drank in power after power, the title fitting them more with each passing second.
Finally, Max stopped. Out of breath, he gazed upon the beings he'd created.
Each one was curvier than hypersexual pornstars. Their muscles made bodybuilders look like sticks. Every movement the two made was sexual and erotic, and they radiated a sense of power as they drew themselves up to their full 12-foot heights.
Britney turned her intense, glowing gaze down on her son, and floated closer. Lightning danced across her fingertips. When she spoke, her voice rattled windows and furniture as it rolled like thunder in her quietest whispers. "Max, dear," she called him. "Would you come closer for a second?"
He did as she asked, and pressed his hand against her skin. It was like touching smooth stone, yet it rippled with inhuman flexibility that no one with that much muscle should have been able to pull off. Sparks of static jolted up his arm. Suddenly, he felt himself move and float up into the air, as Britney used her new telekinetic powers. "Max, my gorgeous son," she breathed, as she pulled him into a hug. "You have no idea what you just created."
"Mom?*
"Oh, I'm much more than that!" Britney announced, eyes wide and gleeful. "I think we might actually be gods now! Mm, I can feel pure power thrumming through my veins. I could kill you without even a thought!"
Max swallowed. Right. His mother certainly was acting differently, but perhaps that was just what happened when you became more powerful than you could comprehend.
"Don't worry, kid, she's joking," Allison assured him. "But fuck, does it feel good to be like this! You've really given us a power trip, Max!"
Britney gently placed Max down on the ground. "Now, sweetheart, what do you want to do with us next?"
