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!

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!

Hachi-Roku Harmony

The act of a male straddling another male in the driver’s seat of an AE86 while engaging in anal sex. With each thrust, the driver presses the gas, letting the legendary 4A-GE engine sing. As climax approaches, he skillfully rev-matches to 7500 RPM, unleashing a high-revving finish—reliable, precise, and, in true Toyota fashion, built to last.

As Joe straddled Jose in the driver’s seat of the AE86, each thrust was met with a tap on the gas, the 4A-GE screaming in perfect unison. With a final rev-match to 7,500 RPM, they reached their climax—executing a flawless Hachi-Roku Harmony that would make any AE86 enthusiast proud.”
