Guess what it's about, if you're correct I'll tell you =)

How can one race without a track?
Should they rely on mercy's grin?
Loves lost labors on his back.
A sickness curdles deep within.

Smiles cultivate a liars thought
Could you, sweet, guess what I mask?
Mistrust and worry so very fraught
You cannot do what I don't ask.

Allow me time to you, regard
As you wait, scream, terror sound
Forewarned that this game is hard
Dragged mercilessly, my heart you're bound.
