A variation on the rusty trombone, the rusty French horn consists of a man giving a rim job to a woman, while also fisting her. This is reminiscent of a musician playing the French horn, as he places his hand in the bell of the horn to alter the pitch of the sound.

After she gave me a rusty trombone, I returned the favor with a rusty French horn.

It's a take-off of the rusty trombone, where you 'toss the salad', but instead of the handjob, you insert your fingers like you're playing a french horn.

"Yeah, I played her like a rusty french horn!"

the woman is lying on top of the man with buttox and vagina exposed and elevated. the man places left hand around womans leg, reaching clitoris with fingers, and stimulating thereafter. with right hand, he inserts however many fingers are necessary to reach maximum pleasure, while simultaneously rimming her anus. (ex. female version of the rusty trombone)

Bill gave me a rusty french horn, but I had some dingleberries that obstructed the air passage, so his tone was heavily affected.
