Alex & Sierra - Toxic (sultry version)
Baby, can't you see
I'm calling
A guy like you should wear a warning
It's dangerous
I'm falling
There's no escape
I can't wait
I need a hit
Baby, give me it
You're dangerous
I'm loving it
Too high
Can't come down
Losin' my head
it's all around
Can you feel me now?
With the taste of your lips
I'm on a ride
You're toxic I'm slippin' under (Ohh Ohh)
With a taste of the poison paradise
I'm addicted to you
Don't you know that you're toxic?
Don't you know that you're toxic?
It's getting late
To give you up
I took a sip
From my devil's cup
Slowly, it's taking over me
Too high
Can't come down
It's in the air and it's Spinnin' 'round and 'round
Can you feel me now?
With the taste of your lips
I'm on a ride
You're toxic I'm...
