A dance with the devil (purposal)

I'll let you take my soul away
If just once you'll give me this
You can have it today
In exchange for momentary bliss

Do with it what you wish
I'm not scared
Because once its Sealed in blood and with a kiss
I won't really care

I've come prepared
Hoping for yes
But I'm fully aware
That you're capable of less

So please grant my request
And dance with me
I've heard you're the best
And I'm sure you'll agree

So take the lead
And I'll be here forever
If we succeed
In dancing together
