Gokkun (ゴックン, Gokkun) is a genre of Japanese adult video in which a woman consumes copious amounts of semen. The word "gokkun" is an onomatopoeia, which translates into English as "gulp"—i.e., the sound one makes swallowing. Whereas bukkake titles predominantly involve men ejaculating on a woman's face, gokkun titles predominantly involve men ejaculating into a woman's mouth. It is not uncommon, in a single movie, for a gokkun actress to swallow more than a dozen cum shots; although typically the gokkun actress is the recipient of semen from only a few men at a time.
