Just walking out to the gym, the swaying of Izzy's hips and her cheeks rubbing together placed Jack in such a position that all of his limbs were kept in place. Even though Izzy was already sweating, this tight fit kept Jack firmly placed in his sister's massive hills, safe and secure. When she got to the line to begin her pacer, Izzy clenched her cheeks tightly one time, just to be sure that Jack wasn't going to escape the monumental torture she was going to dish out. Jack heard the starting bell ring, but he also heard a faint rumbling noise.
As Izzy's pace grew faster and faster to match the rhythm set by the pacer, Jack's environment grew tighter and tighter, despite Izzy's sweating practically raining from above. He was still able to breathe, which was nice, but the air, if you could even call it that, was stale, clogging Jack's nose and forcing a few tears out of his eyes. But it was about to get a lot worse for Jack. The rumbling Jack heard at the beginning of the pacer had recently grew louder and louder. When Izzy was about to make her fourteenth bell, it happened. It was relatively silent to the other kids who were doing the pacer with Izzy, but within the confines of her spandex, it sounded like a cannon firing. Worse than the sound was the stench.
When the noise erupted, the smell immediately followed, covering Jack's whole body and driving up his nose. He could barely breathe, but the little bit that he could was the foulest stench Jack had ever encountered. On top of that, the shaking from the massive fart had covered Jack in his sister's sweat and driven him a little further into her ass. Fortunately, Jack wasn't too close to the hole which dispersed this rancid smell, but he was still too close for comfort. Outside of this noxious chamber, Izzy was having the time of her life.
The sensation of Jack's movements within her tight spandex made Izzy giggle and coo. She knew that it was her brother, which in a sense made this extra weird, but at the same time made it all the better. Izzy loved her brother very much, but also loved to mess with him. On top of the fact that Izzy was torturing Jack, she was enjoying the squirming he made. It made her feel in control but the physical sensation was so much better than that. Izzy giggled about the thought of what her brother was going through, but she was starting to get tired.
The pungent odor seemed to linger forever as Jack tried his best to maintain consciousness. The rubbing of Izzy's buttcheeks had drained him of most, if not all, of his energy. His body lay limp, completely at the mercy of Izzy and her ginormous behind. Just as Jack was getting ready to pass out, the rubbing of Izzy's cheeks had began to slow down. She was done with the pacer! He didn't have to suffer in here any longer!. The sudden joy from the end of the pacer seemed to almost completely rejuvenate Jack, and he regained full consciousness.
Sweaty and tired, Izzy entered the locker room after completing her pacer, and undressed, ready to take a shower. At this point, she completely forgot about her older brother being trapped within the confines of her cheeks, and went off for the showers without giving it an extra thought.
Is Jack still stuck with Izzy as she takes a shower? Or did he fall down with her spandex?
