When a chick eats your ass out and gives you a stroke job at the same time

favorite piece of trash of Oscar the Grouch, as referenced by the song "I Love Trash" on the album "Sesame Street - Platinum All Time Favorites"

Having your brown eye tongue punched while simultaniously reciving a hand job.

The sexual act of eating a guys ass while giving him a handjob from behind.

when a male or woman (preferably woman) is licking a mans ass and then reaches around and gives him a hand job

This stunt can be done by either two guys or a male and female. this is how it works. lets take the two guys for example, one will get on his knee's and will be facing the guys ass while he stands ( note: must be naked for stunt to work ) . the one on his knees begins to give the one in front a reach around.( just like using a trombone ) but trombone's are used by not only your hands but your mouth. so this is where the "rusty" part takes affect. the one on his kness will begin licking/eating out the ass infront of him. there you have it folks, the rusty trombone!

sexual action in which a mans asshole is rimmed while he is receiving a reach around..
