I got a letter just the other day
She sent a picture, but she didn't sign her name
She wore high heels and a little black lace
I knew her body, but i couldn't see her face
She didn't leave a number, not an address or a clue
But something in that photograph reminded me of you
Baby, let's put the x in s**
Love's like a muscle and you make me wanna flex
Baby, let's put the x in s**
Keep it undercover, baby let me be your private eye
I got a call in the middle of the night
Heavy breathin' never sounded quite so nice
She said "oh yeah, i wish that i was there"
I asked who was calling, but she wasn't playing fair
Sometimes you gotta suffer for the pleasure that you seek
You're beggin' for an eyeful but you only get a peek
Baby, let's put the x in s**
Love's like a muscle and you make me wanna flex
Baby, let's put the x in s**
Keep it undercover, baby let me be your private eye
I heard somebody knockin' so i opened up the door
She wore a hat, shades, and a trench coat
Wasn't wearin' that much more
She said she knew my secrets but i didn't have a clue
Then i saw those black lace panties and i knew that it was you
Baby, let's put the x in s**
Love's like a muscle and you make me wanna flex
Baby, let's put the x in s**
Keep it undercover, baby let me be your private eye
Let's put the x in s**
Love's like a muscle and you make me wanna flex
Baby, let's put the x in s**
Keep it undercover, baby let me be your private eye
Let's put the x in s**
Love's like a muscle and you make me wanna flex
Baby, let's put the x in s**
Keep it undercover, baby let me be your private eye
Let's put the x in s**
Love's like a muscle and you make me wanna flex
Baby, let's put the x in s**
