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, 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 "O h 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 sex
Love's like a muscle and you
make me wanna flex
Baby, let's put the X in sex
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 wasyou
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,
baby let me be your private eye
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,
baby let me be your private eye
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,
baby let me be your private eye
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
