Black Widow sacrifice

A Sacrifice, a sacrifice,
you say you wanna sacrifice.
You say the words to easily,
to know just what you mean.
One black hand and one white hand,
I slaughtered with your knife.
I know full well you have a loss,
a thing to match their blood
The sacrificial knife is stained with [...]
and held on hair,
the blood is mixed within the cup,
and drunk by all who watch.
You [...] a power [...] touch.
You’ll never get to power just by playing nasty games.
A sacrifice, a sacrifice ...
One black hand ...
When I crossed the abyss two thousand years ago,
I never even dream so many power I would reach.
Till the point on my knife reached my lovers silken throat,
the only thing I'd sacrificed have been my fathers' sheep.
