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 fifty cum shots.
Leah Luv receives 79 open mouth facials. She swallows five mouthfuls throughout the scene.
