Similar to the rusty trombone and rusty trumpet, this sexual maneuver is a collaborative effort. It requires four
people: one man, two skinny women, and one fat one. The fat woman gives the man a rim
job while giving him a handjob (the rusty trombone). The man gives one skinny woman a rim
job while fingering her clitoris (the rusty trumpet). This woman does the same for the last woman (the second rusty trumpet). This last woman also gives a good rim
job and fingering to the fat woman (the rusty tuba).
