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 "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 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 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, 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
