Her Pet No Longer

She summoned a demon, but now it's in charge.

Black nails tease her sweet, soft skin
I smile as she quivers from the energy within
She summoned me here this night those many moons past
Then using her spells and her powers, she did hold me fast

But tonight had no moon you see
And in the dark my power it grows times three
When she came tonight to sate her need
She found herself betrayed indeed

Her soul is now mine to twist and torment
Then out into the wider world I'll take my dark bent
I think I shall take her with me to let her see
What I will do to this world that she has given me
