pistoning
Moving like cylinders
Pistoning describes the repetitive back-and-forth motion of a piston in an engine cylinder.
By extension, it applies to any vigorous thrusting action that mimics this mechanical rhythm: His legs were pistoning as he sprinted up the hill.
The term appears in both technical contexts and vivid descriptions of physical exertion or sexual activity.
