Sexual act in which a woman (or man) drinks the semen of a large group of men, all at once. Gokkum is often performed by having 30-100 men ejaculate in a container, following which the woman drinks the entire amount of liquid without pausing. Differs from "bukkake" in that the semen is swallowed rather than ejaculated on the woman's face/body. In gokkum, the woman remains relatively clean and dry.
