Kneeling beside her silent form , he let his tongue travel the length of her neck , the blood there still sweet , but too dry , wrong . He growled . Her heart still throbbed , but it was pushing more venom than blood now . The girl twitched , brushing off the small purple flowers that sentimental fool of a vampire had left for her along with his gift of immortality .

Question: Why would the bite hurt so much ?
Answer: It was from the undead .It did n't puncture their dry skin .It left just a small purple mark .It did n't result in any blood .
