Aesthetic Perfection - Filthy design

You know it turns,
It turns my stomach just to watch,
And though it hurts,
Restrain myself from taking part,
As every nerve,
Dulls and dies away,
For what it's worth,
Your love's so hard to gain.

Why don't you come in my...?
Why don't you come in my...?
Why don't you come in my...?
Why don't you come in my...?

You're just so dirty,
You're just so dirty,
You're just so dirty what you do with that mouth.

I'm wanting more,
I'm wanting more than one can give,
And every pore,
Has left me restless in my skin,
But I'm not sure,
What I'm gonna be,
I just adore,
The tension that it brings.

Don't you wait,
The filth won't come off,
Don't you hate?
It's part of our design.
