Gokkun(ゴックン) is a Japanese term for a sexual activity in which a person consumes the semen of one or more men, usually from some kind of container. Commonly used containers in this genre include cups, large beakers, bowls, baking pans, and wine or cocktail glasses. The vast majority of these scenarios involve the semen of multiple men. Pornographic films with gokkun scenes have had up to 200 men participating.
