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.

The Beverly Hillbilly

Having sex with a person that has a colostomy bag then force all the shit in her colostomy bag to one side so it’s taught then burst it with a pencil so rains down like black gold Texas T.
