When two dicks rap around each other like slugs during sex. Masturbation in this position can cause sensation for both dudes (or girls with dicks).
Alex: RUSTY PIPELINE!

Noah: OKAY, MY DICK ON TOP THOUGH!

Get the rusty pipeline mug.
When two dicks wrap around each other like slugs do during oral sex. Looks like the inside of a pretzel, but made with quality white meat (dicks). Masturbation in this position can cause massive sensation for both parties. Feels great.
Noah: Mike did the rusty pipeline with me last night. I jizzed so much. Awwwwwwwwww...

Mike: It was SWEEEEEEEEEEEEEEET!
