This is probably the sexiest song I could think of. Just ignore that she's singing with her brother...
Poe - Hey Pretty

I can't remember the inane things I started babbling about then
I know it didn't really matter, she wasn't listening
she just yanked up on the emergency brake, dropped her seat back and told me to lie on top of her
on top of those leather pants of hers, her hands immediately guiding mine...

This is from Y100 recording sessions which you can buy here


This song is sexy and bitter. buy album
Handsome Boy Modeling School - I've Been Thinking (feat. Cat Power)

I was hypnotized
By your fairy eyes
Like a tiger in the dark
You were hungry from the start

When I saw you on the street
I just had to look away
You were so sweet
Sexy Steez
Lay back, relax
Street boy, please
Wait a second
It's gonna take awhile

Another great one from Cat is:

Cat Power - Sea of Love

Come with me
My love
To the sea
The sea of love

I wanna tell you
How much
I love you

from the Juno OST
