Rusty Tromblumpkin 

A combination on the Rusty Trombone, (a sexual position in which a girl licks the man's asshole while giving him hand relief from behind), and The Blumpkin (a sexual position in which a man takes a dump and simultaneously receives oral pleasure). A modified toilet or a lot of creativity is required.

I received a quite satisfying Rusty Tromblumpkin last night!

I wish I had time for a Rusty Tromblumpkin!

Rusty Tromblumpkins are quite addictive!

Rusty Tromblumpkin 

A mixture between a rusty trombone and a blumpkin.

In a Rusty Tromblumpkin, the male recieves a hand job while depositing feces directly into another person's mouth.

No one talked to Catye anymore since her mouth reeked of feces from giving Matt a Rusty Tromblumpkin.

Rusty Tromblumpcano 

n. The extreme fetish act that involves the Rusty Trombone, (a sexual position in which Partner B licks Partner A's asshole while giving him hand relief from behind) only partner A being relieved is having violent diarrhea and partner B is vomiting into the asshole.

While in Europe, I made a German prostitute give me a Rusty Tromblumpcano after taking a large amount of laxatives.
