Rain Degrey can take the pain. She goes to a happy place inside and can deal with almost anything you can throw at her. So how do you make this tough girl cry?
We found out. You severely bind her in metal so she is trapped on a Sybian. Then you rip orgasm after orgasm out of her body until there is nothing left, no thought process, no cognitive thinking, no sense of self, only survival. The lungs fill with air, the heart continues to pump blood. The pleasure/pain of the pleasure is an overload of the senses.
Rain is reduced, she is broken, her brain is offline, she is gone. She knows she can't stop it. Somewhere deep inside the horror, in that one moment of total hopelessness, fear manifests itself into tears, a cry for help, the mind reaching for mercy when the brain can't form recognizable speech in it's defense.
