With her brother's body firmly in between her fingers, Izzy hovered Jack over the opening to her gray right sneaker. "No!" Jack cried out. "You'll kill me!" Izzy moved him closer to the shoe, close enough to where Jack could smell a musty odor coming from the opening. He gagged. "Don't worry Jack, it may be rough, but I'll be sure not to kill you. You're my brother after all, and I love you as such." She chuckled as she dropped Jack into her shoe, finding joy in watching him try to climb out. Izzy casually thwarted his efforts by lifting the shoe in the air and holding it sideways, causing Jack to fall on a steep incline to the toe area of her shoe. All the while smiling, Izzy placed the shoe on the floor and began sliding her foot inside. Jack looked on in horror as the sock-clad foot leered his way.
*SMUSH*
Pulling the shoe on with some force, Izzy firmly scrunched her toes into Jack, rendering him in utter immobility and discomfort. Aside from the physical distress he received from his sister's foot having complete control over him, Jack was beginning to feel the effect of the heat, smell, and moisture of Izzy's sweaty shoe and sock. This, he thought, was one of the worst possible outcomes he could have imagined resulting from his sister finding him at this size. There wasn't anything he could do about it though, now it was time to try and endure an excruciating amount of foot play, courtesy of Izzy.
After having laced up her shoes, Izzy walked out of the girls' locker room and into the gym. She felt Jack squish against and between her toes which gave her too much satisfaction to resist expressing. She scrunched her toes, rubbing Jack in between them. He moaned and groaned, embarrassed by the predicament he was in. Not only was it outright disgusting, but this was his sister. He couldn't really expect anything less though, she had been this way all her life. The walk into the gym was a piece of cake, even though Izzy casually scrunching her toes wasn't the most pleasant experience in the world. However, things exponentially grew worse as the class slowly began to transition into full throttle.
It began with casual stretching, which wasn't a problem for Jack considering stretches don't work the feet too much, then transitioned into a light jog, and this is where Jack's suffering began. Within the first ten seconds of Izzy jogging, Jack found himself at the toe end of her shoe to completely underneath the sole of her foot. Here, it was the warmest and most moist. Not only that, but the forceful step of Izzy's foot each time she landed put an immense amount of pressure onto Jack, pressing him firmly into his sister's smelly sock. His nose stung, it was difficult to breathe, and his body was aching from getting pounded by Izzy's foot. While he was suffering, though, his sister was having the time of her life. She made sure to put some extra gusto into her jogging when the pace picked up, landing more firmly on her right foot than her left as she jogged. Once the jogging ceased, Jack breathed in a sweaty sigh of relief. Izzy's foot at rest, while unappealing, was a lot better than when active. He was now covered in a sheen of the sweat sopping from his sister's sock, but that was the least of his concerns. Not long after the jogging had ended and the class was sent on a cooldown, Izzy pretended to see a bug and went to squish it.
*SQUELCH*
*CRUNCH*
"God, Bella, is everything okay?" One of Izzy's classmates had spotted her rubbing her foot on the ground with force and thought it a bit strange. "Oh," Izzy said, startled. She immediately stopped rubbing her foot on the ground, to Jack's pleasure. He felt like his body was about to give way and splatter. He wasn't so sure that Izzy was trustworthy enough to keep him alive, even if she was his sister. But, thanks to the intervention of a fellow student, she did. Feeling her shoe coming loose, Izzy went to sit down and untied it, lifting her foot out to find an utterly exhausted Jack laying like a starfish on the insole of her shoe. Huffing out of fatigue, Izzy smiled. "I guess I gave you quite the workout, huh? Don't worry, there's more to come." She picked Jack up, who could barely speak to protest, before pulling back her sock and tucking him inside. Instead of moving him under her foot, however, Izzy kept him pressed up against her ankle. "I'm sorry for going overboard there," she apologized, "I'll try not to be too hard on you for the rest of the class." Hardly able to express his gratitude, Jack closed his eyes. He wanted to pass out, but couldn't. Instead, he remained right where he was as Izzy resumed her class participation.
Does anything happen to Jack before the class ends or is he able to stay with Izzy long enough to get back to the locker room?
