Rain Degrey can take a pain. She goes to a happy place inside as well as can understanding with roughly anything we can chuck at her. So how do we have this difficult lady cry? 
We found out. You exceedingly connect her in steel so she is trapped on a Sybian. Then we slice orgasm after orgasm out of her physique until there is zero left, no suspicion process, no cognitive thinking, no clarity of self, usually survival. The lungs fill with air, a heart continues to siphon blood. The pleasure/pain of a wish is an overkill of a senses.
Rain is reduced, she is broken, her brain is offline, she is gone. She knows she can’t stop it. Somewhere low inside a horror, in which a single impulse of sum hopelessness, fright manifests itself in to tears, a cry for help, a thoughts reaching for forgiveness when a brain can’t form tangible debate in it’s defense.
