I think these two amazing women are in it to the pain...that when one actually breaks something of the other, instead of forcing a give, it will instead cause her to retaliate as best she can and break something back.
A fight to the pain...where each doesn't just want to dominate, but wants to engrave on the others heart and soul just how much weaker she is than her opponent...that she didn't just try, but literally gave and tolerated everything she could, and it wasn't enough!
Its not about scars and permanent damage (although it sounds like that isn't impossible!), but instead dominating, humiliating...through pain, through deprivation, through control.
I could be wrong, maybe its just about a contest to prove who's stronger...we can only wait and see who's threshold is lower...or, if I'm guessing correctly, just how amazingly high they are...and just how much they want to win.
These two busty women may have more heart than the toughest of warriors...excited to see how far it goes!
