I will label the parts to who I think would be singing that part.
Poison- Groove Coverage
Bella:
Your cruel device (Edward's power? lol)
your blood, like ice
Edward:
One look, could kill
My pain, your thrill...
Edward:
I wanna love you but I better not touch
Bella:
I wanna hold you, but my senses tell me to stop
I wanna kiss you but I want it too much
I wanna taste you but your lips are venomous poison
Your poison running through my veins
Your poison
Both:
I don't wanna play these games
Edward:
(I wanna love you but I but I better not)
Bella:
Poison
Edward:
Your mouth, so hot
Your web, I'm caught
Your skin, so wet
Black lace, on sweat (Breaking Dawn reference lol?)
Edward:
I hear you calling and it's needles and pins
I wanna hurt you just to hear you screaming my name
Don't wanna touch you but you're under my skin
Bella:
I wanna taste you but your lips are venomous poison
Your poison running through my veins
Your poison
I don't wanna break these chains
