rusty melodica 

Anilingus performed on female, accompanied by manual clitoral stimulation.

My secret girlfriend likes rimming and fingers, so I think a rusty melodica will be right down her alley.

Melodical-Charging-Relevance-Theory 

This is the theory for sounds where one specific sound doesn't start with its own climax.
Simpler said, the sound has to build up volume first and the climax starts 5-30 milliseconds later.
Looking at another perspective, it is very likely that drum sounds instantly reach their climax where as (mostly noticeable) EDM sounds that have some kind of distortion to them, don't reach their climax instantly, but get them more likely delayed.

I think on this sound the Melodical-Charging-Relevance-Theory kicks in. This seems very delayed.

melodica 

A sub-genre of electronica music that makes heavy use of melody. The melodies in this kind of music are usually very complex. Whereas trance music might play the same couple bars of music like 36 times in a row, melodica music doesn't tend to repeat itself. Generally, melodica does not have lyrics.

Melodica makes use of complex and unrepetitive melodies to hold the listener's interest.

melodica 

A musical instrument that resembles a handheld piano. It is playing by blowing into a tube and makes a sound akin to a saxophone.

My favorite instrument to play is the melodica.

Rusty Melodica 

The equivalent of the rusty trombone when performed on a female. Consists of orally stimulating the asshole while manually stimulating the pussy, mimicking the actions of playing the melodies.

Jeff: What’s the best way to eat a woman out?
Greg: Give her the ol’ rusty melodica, man, bitches love that shit.
