I've got a new disguise
Loock into my eyes
There is something tou don't know
I want to show you
Try another plan
Decieve me if you can
Everywhere you go you'll find me there
You're so easy
You're so wet inside
And you're shakin' all over like
The leaves on a three
There is no way out no escaping from me
Our senses are one but the reasons is lost
Cos I am what I am
And I do what I do
Youre number is my number
Unlearn what you ewre taught
I contemplated
There is nothing to conceal
I want to show you
Try to understand
Deceive me if you can
Now there's nothing you don't know
