She tries to resist

Hearing my first orders to her Cassie panicked and started trying to roll out from under my foot. Her feet were kicking wildly as she tried desperately to escape. I slowly increased the weight I was putting on my foot. The more she struggled the harder I pressed down on her. I could tell it was getting harder for her to breathe and knew she would pass out soon. Not wanting her to be **** again so soon, I told her calmly

"Stop struggling or I will break your ribs"

That seemed to do the trick because she stopped struggling immediately.

"Much better. Now when I remove my foot I want you to remain flat on your back and not move at all." I told her in a calm but firm tone.

Slowly I lifted my foot off her chest and stood with one foot on either side of her stomach. She seems stayed perfectly still barely even daring to breathe.

"Very good!" I told her encouragingly "See it's not so hard. Just do as you're told."

I walked over to a nearby table covered in toys making sure she heard my footsteps heading away. I quickly picked out the toy I need for what I wanted to do next then turned to see if she was still obeying my last command.
