Milking the chamber 

When toking from a bong, one must hold a lit lighter to the end of the chalice, put his mouth to the opening at the top of the bong and breath in to draw the smoke up and into the chamber. The process is referred to as 'milking the chamber.' Once the chamber has been milked appropriately, the toker takes his thump from the rush hole and breathes in HARD, sucking up a sweet blend of air and smoke which may give him a harsh headrush.

"Dude, you milked that chamber nicely, now take yo' thumb off the rush hole and BREATHE IT!!"

forced milking 

When you tie up a guy and jack him off repeatedly without stopping. After he cums a couple times, he'll become overly sensitive, and continuing to jack him is pretty intense overstimulation, so the body's natural reaction is to move away. That's why it's important to tie him down first.

Usually found in bdsm encounters.

"forced" distinguishes it from other things that are also called milking.
