Out of tune harmonica 

Blowing into your partners anus during analingus, in order to build up enough air to cause sound to permeate from the sphincter.

"I got a little too into it last night and accidentally made Jill into an out of tune harmonica."

The Hillbilly Harmonica 

The stratigic placement of a musical instrument in your girls mouth, whilst plowing her from the back.

When she's screaming like a boar, gently place the Harmonica in her mouth to complete the Hillbilly Harmonica.

What did you do last night mate.

" well we had good night until I have her the Hillbilly Harmonica"

Its where you put a Harmonica in your partners mouth while she's being plugged from the back.

She's want pleases but it definitely made a fucking symphony.

Devil's harmonica 

The act of fellatio, performed by two mouths on the same penis.

The best head I ever got was from Carrie and Blair. Those two were playing the Devil's harmonica!

Play the harmonica 

when you drop a wafer, so you blow on it to make sure it has no germs.

"oh no, your wafer!"
"ahh it's ok, let me just play the harmonica"

Chi-Town Harmonica 

The act of running your partner's erect penis back and forth along your tracheostomy hole while humming different notes as if playing a harmonica.

It sucks that she had to get a tracheotomy but she gave me a chi-town harmonica last night and it felt amazing!

two-man harmonica 

For all the musicians out there who enjoy the harmonica and occasional percussion. A play on 69, one woman laying on her side and men on both sides facing her. Men blow on the harmonica while she plays the drums 🥁

“Hey man, I think we have a shot at a two-man harmonica tonight”
“No way bro. You think our sticks will get some action too?”
