2nd paragrph of my short story

Just kill me quickly, I thought as I turned, with some effort, to see him slowly getting closer with a smug, triumphant smile on his face as if he could read my thoughts. "Now I have you, quite fast you are," he said, "So how should we go about this, hm?" he continued in a casual tone as if he were commenting on my clothing. "Please" I whispered, my voice cracking, "Not a chance" he chuckled as he pulled out a sharp knife with a long, thin blade. "where should we start?" he asked again,"oh, I know." and with a sly smile he started to slowly, carefully trace the outline of my lips with his knife, I could not yet feel the pain but I knew if I spoke a word, any small movement of my lips, he would intentionally "slip" and the blood would start to flow. Then it hit me! A plan. For it to work I would have to wait until he had finished with my lips,it will no doubt take all my effort not to cry out in pain but it was the only chance i had, the only way to preserve my life, and it was a chance I was willing to take.
