On the way to school, Alex and his mom made small talk for a few minutes, before eventually falling silent and letting the radio fill the void. As Iris focused on the road, Alex found himself bored, and let his eyes wander around the car unconsciously as he thought about the dictaphone he had in the backpack currently sitting at his feet.
As Alex considered what he'd do first with his new reality-altering powers, his eyes found their way to his mother's foot on the gas pedal one seat over. Alex often found his eyes drawn to his mother's delicate feet, with their perfect toes, which she kept brightly painted, and their high, graceful arches. He had a serious foot fetish, and he hated that his mom's feet were so good at activating it. "But..." he thought to himself as his mom flexed her toes forward, pressing down a little harder on the accelerator, "they just look so damn sexy."
Alex would never admit it, but he had even had dreams about her gorgeous body. In the wildest of these dreams, she would appear from nowhere, hundreds of feet tall and completely nude. She would laugh as she destroyed buildings and cars beneath her giant feet and ass, before then using her feet to toy with his tiny body. He would usually be subjected to her massive toes rubbing him around between one another until he was eventually woken up by a wet mess in his sheets.
Alex tore himself away, looking out the window to avoid thinking any more about his mom's feet, and hoping she hadn't seen him peeking at them. "God, this drive is so boring," he thought, checking the time on his phone. Still 20 minutes to go. Bored, Alex found himself staring at Iris' feet again. In her psuedo-roman-style leather sandals, they were wonderfully on display. As he watched his mom curl her pretty toes together and release them for what felt like the 15th time, Alex finally cracked. He NEEDED to get close to those gorgeous feet. And with the dictaphone, he could finally make that happen.
Alex grabbed the dictaphone out of his backpack and held it to his mouth. Quietly, he recorded, "Nobody will notice me using the dictaphone unless I want them too. Also, nobody but me can use the dictaphone. And finally, I can never lose the dictaphone. If I want it, I can summon it at will." Alex grinned as he heard a sparkling sound. His mother, who had been eyeballing her son as he whispered into what looked to be a voice recorder for some reason, suddenly returned her attention to the road and thought nothing more of what had just happened.
Seeing he could now do as he wished, Alex turned his attention back to his mother's gorgeous feet. Holding the dictaphone a little more casually now, Alex recorded again, "My mom is 500 feet tall. Instead of driving me to school, she's walking me there, letting me ride between her toes as she usually does now. Oh, and also, she can't hurt me, and she can't hurt anybody else unless she intends to either!" Now having thrown caution almost completely to the wind, he waited for the dictaphone to work its magic.
Again, Alex heard a sparkling sound indicating the dictaphone was indeed working. However, he already could have discerned that anyway, because as soon as he had finished recording, Iris started shooting up in height beside him. Alex watched as his mom blasted through 10' tall in a second, and the roof of the car as well. Within a few more seconds, His mom's ass had grown large enough to cover the car entirely as she hit 50', then 80' tall, with no signs of stopping. Luckily, his instruction that Iris be unable to hurt him meant Alex was spared the fate of the car, which had been flattened to a pancake of steel beneath his mom's growing, incredible rear. Instead, he found himself suddenly sitting on the toes of his mother's bus-sized left foot, the soft skin stretching beneath him as she continued to swell up to an incredible 150' in height.
At this point, Iris' thighs and ass were getting too wide for the two-lane suburban road she was sitting in the middle of, and her butt began to spill over onto the sidewalks on either side of her as she continued growing. As she shot past 250' tall, her hips slammed into the houses on both sides of the street, having already steamrolled over the front lawns and still showing no signs of slowing down. Alex sat on just the big toe of his mother's massive left foot now, it alone currently being bigger than a sleeping bag compared to him. He watched with glee as his mom kept growing larger and larger.
Iris continued to grow at an intense pace, slamming through 350' in just a few more seconds. She continued through 400' tall to 450', and finally settled at 500' tall from head to toe, just as Alex had recorded. For a second, his mom sat there stupefied, with half the neighborhood beneath her ass and her son on top of her toenail. However, Alex only had that one second before he found reality shifting around him suddenly, his sight blurring out.
When it returned, Alex was sitting between two walls of soft, warm, pink flesh. Each was about as tall as he was, and sitting down he was nestled into a comfortable nook where the walls met behind him. Looking upwards out of the crevasse, Alex could see two massive legs stretching up into the sky, before disappearing into the world's largest pair of khaki shorts. Above that, a navy blue tank top struggled to hold back two breasts the size of blimps, which were presently obscuring the face of the redhead above them.
Of course, even without being able to see her face, Alex knew this massive woman was his mom! He had recorded that he was riding between her toes, and now he was. For her part, his new titan of a mother was walking along leisurely, now making her way through the countryside around the suburbs rather than directly through them. After all, she wouldn't be able to fit even one foot on the road she had been driving on before this! With every step of his mother's huge foot, Alex found himself lurching upwards and forwards before being dropped suddenly back down to earth. Thankfully, the soft skin of his mother's massive toes surrounding him made the ride comfortable enough. He braced himself in the crevice between her big toe and its neighbor, wedging himself in, with his legs pushing against the soft sole of her house-sized sandals, and got ready for the ride.
