Double tap

It hurt. 

It hurt like hell. My eyes were in pain I'd never experienced before. Pain, that I had nothing I could draw a valid comparison too. By the time I fired the first shot and moved to correct with another one, the pain rapidly spread all over my body. 

In a certain sense, it felt as if somebody was pulling out my fingernails… but from all over my body rather than just the tips of my actual fingers. 

But between this pain and the pain I would feel if some fucker managed to pierce Fay's delicate skin and cause her lovely face to twist in pain…

A shudder moved up my body, allowing me to bear with the pain for just long enough to align the iron sights of my pistol and the very middle of Fay's assailant's forehead. And then, by simply ignoring the pain and using all my willpower to continue, I pulled the trigger again. 

In fact, I sort of hesitated. Right as I was about to do the deed, a single doubt appeared in my mind.
