Kate's Place Tiny Brother VS Big Sister chapter 23 by copier · original author: rpcity

Kate sped away from your aunt's apartment toward her own complex. It wasn't far, but Kate drove the entire length of your aunt's parking lot as well as her own. She made sure to hit each and every speed bump along the way without pausing to slow down. With each bump the car hit, Kate's full ass was lifted off of her leather seat only to come crashing down on your body again. Each impact was as bad as the first. Though it was dark in the car, your eyes had adjusted to the lack of light and you were able to clearly see Kate's sweatpants each time she plopped down on top of you. At least, until you started going up with her.

After a short but painful drive, Kate parked the car. She rubbed her ass happily across her seat, thrilled with the prospect of a new client she could work with 24/7. She exited the car and smiled seeing her driver's side seat empty. She rubbed her hand across her ass and confirmed your presence there. She wasn't really able to feel your flattened form, but there was a slight change in texture where your body ended and her sweat pants began.

The trainer happily skipped to her apartment, peeled you off her ass, and deposited you on the counter. She looked at you hungrily as she waited for you to reform. Kate wasn't a particularly patient person, but she forced herself to keep her hands off of you until you were once again three dimensional. Finally, you were lying on your back panting for breath, your fully formed lungs gulping in oxygen.

Kate frowned. "No wonder your aunt called me. That was far too slow of a process Allen," she reprimanded you, "Fortunately for you we've only just started our training process. By the time we're done, your body will put itself back together in a wink!" she exclaimed with a smile.

"I know you've got lots of experience getting squashed in your life," Kate continued, "But it's been so intermittent and you've resisted it so much that your body never really grew through it. These workouts are designed to help your body adjust and build your tolerance. Just like seeing in the dark!" she said happily.

"But for them to work, you need to cooperate. The more you resist, the longer we'll have to spend on each element. A month each was an estimate, but if you're cooperative and embrace the training, it could go faster. If you fight it, including mentally, I promise it will take longer."

You felt an urge to try to scramble away, but you were trapped in her apartment. There was nowhere for you to go, you were trapped with this psycho! You hated being squished, you didn't see yourself ever, ever, embracing her workouts if they were anything like today.

Kate continued her explanation. "Now, like anything, practice makes perfect. So the more you exercise the quicker your body will adjust. That's why my 24/7 attention is going to be so important. For pain tolerance, I promise you that you that I will squash and flatten you as much as I possibly can as often as I possibly can in any way I possibly can. No breaks, no rest. That's the only way to build up a tolerance."

Kate seemed to finish her explanation. You were enraged at her idea of "training", but what else did you really expect from your batty aunt?

"Are you insane?!" you yell. "There's no way I'm going to let you do that!" you scream in defiance.

Kate clicks her tongue at you in disappointment. "Tut tut Allen, your aunt told me you were a good listener. This is what I'm talking about, cooperation is important. But even if you don't cooperate, this is happening. It's for your own good," she said sternly.

With her explanation out of the way...
