Hungry Lurker

Won’t you feed me?
I’m hungry as can be,
For hours I’ve quested,
As a host, you can’t be bested.

What do I give in return?
Something that may make you burn,
You won’t feel my bite,
I can feast all night,

If you let me stay,
For a week and a day,
My gifts will multiply,
A fever, a rash and aches that will make you cry,

You don’t want to die?
I won’t lie
I’m hungry as can be,
Won’t you feed me?
