Rusty Piston

A sex act involving three men. The first man stands in front while he is penetrated by the second man, and the second man is penetrated by the third man. The second man thrusts between the other two men, thus creating a piston motion.

Bill: Last night, I went home with these two hot guys, and I got between them and we did the rusty piston.
Jeff: Awesome! Wish I could have been there.
