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 sex
love's like a muscle and you make me wanna flex
Baby, let's put the X in sex
keep it undercover
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 begging for an eyeful but you onle get a peek
Baby, let's put the X in sex
love's like a muscle and you make me wanna flex
Baby, let's put the X in sex
keep it undercover
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 sex
love's like a muscle and you make me wanna flex
Baby, let's put the X in sex
keep it undercover
let me be your private eye!
