Try to stand your ground

You know that it would be humiliating to fall down, kneel, drop, or show any sign of defeat in front of this girl. Fighting against the sickening pain, you manage to stay up, your legs trembling from pain. "Wow, didn't think you would be standing," she remarks, and for few seconds you actually think you won against her. But then came another knee to your already hurt crotch. Then another. Then another. You try to hold on but to no a avail. Your body loses strength and you slump over.
