Narrative:
We had been cleared to 14000 ft as a discretionary clearance from 38000 ft when the cabin pressurization system began to malfunction. We took the prescribed emergency actions. We donned the crew oxygen masks; established crew communications; and deployed the passenger masks as we cut power; deployed the airbrakes and descended on the airway. I asked the pilot in command (PIC) whether he wanted to [advise ATC of the situation]. He stated 'no'; we were in protected airspace during the rapid descent and once at the lower altitude the urgent scenario was effectively handled; no services or priority from ATC was then necessary. The controller did voice concern; noticing the rapid descent. The PIC admitted a pressurization anomaly and declined to elaborate further; but assured them the situation was under control.
