When one man fucks another man's penis.

The manoeuvre requires two erect dicks; the first one being held steady by the recipient as the second one is forced into the first one's urethra.

Pipe Cleaning requires a tremendous amount of preparation to pull off, mainly a lot of breathing and urethra stretching excersizes by a willing recipient.

Pipe Cleaning is an extreme evolution of "Docking".
Man 1: "Fancy getting fucked up the piss hole?"
Man 2: "A Pipe Cleaner? Sign me up."
