Laying a girl on her side, and rubbing your lips back and forth across her vagina and anus while blowing simultaneously, treating her two love holes as you would the holes of a harmonica. To better create the rusty harmonica effect you may also cup her vagina lips and anus in your hand as you would hold a harmonica.
"Dude, I gave your mom the most righteous rusty harmonica last night!"
"Oh yea? What song did you play?"
"Blowin' in the Wind."
"Oh yea? What song did you play?"
"Blowin' in the Wind."

The act of blowing into a woman's anus while cupping your hand in front of her vagina as if to tune the note. Similar to the rusty trombone for a man.
