rusty

Rusty trombone is a sexual act in which a man stands with his knees and back slightly torqued with feet at least shoulder width apart to expose his anus. A person typically kneels behind the man and performs anilingus while reaching up beneath the scrotum or around the body to manually administer rapid up and down motions of the penis, mimicking the motions of a trombone player. The act is defined primarily by the physical orientation of the partners, the combination of anilingus with manual sexual stimulation and the resemblance of the anal sphincter to a trombone mouthpiece; however, other positions and variations are possible.
