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 her number, not an address or a clue
But something in that photograph reminded me of you

Baby, lets put the X in sex
Loves like a muscle and you make me want to flex
Baby lets 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 breathing never sounded quite so nice
She said ooh yeah I wish that I was there
I asked her who was calling but she wasn't playing fair
Sometime you gotta to suffer for the pleasure that you seek
Your begging for an eyefull but you only get a peek

Baby lets put the x in sex
loves like a muscle and you make me want to flex
Baby, lets put the x in sex
Keep it undercover baby let me be your private eye.

Oh yeah (yeah)
I heard somebody knocking so I opened up the door
She wore a hat shades and a trench coat
wasn't wearing 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 lets put the x in sex
loves like a muscle and you make me want to flex
Baby, lets put the x in sex
Keep it undercover baby let me be your private eye.

Lets put the x in sex
loves like a muscle and you make me want to flex
Baby, lets put the x in sex
Keep it undercover baby let me be your private eye.

Lets put the X in Sex
Loves like a muscle and you make me want to flex
Lets put the X in sex
Keep it undercover baby let me be your private eye

Lets put (fades...)
