Piston Shot is a term used in pornography. It refers to the filming of closeup of genitals during sexual intercourse to record actual penetration. In 1980s, in many movies, screen-actors "pretended" to have sex while their, although naked, genitals were obscured with their physical position. Actual sex was recorded with different performers with closeup of their genitals while hiding their faces and rest of the bodies. Both kinds of scenes were later mixed with editing to give an illusion of credited actors having sex.
