What is gokkun?

Gokkun is a fetish in Japanese pornography that involves a person consuming the semen of multiple men, typically gathered in a glass or other container. The act is often portrayed as a form of erotic humiliation and is considered taboo in many cultures. Gokkun is typically seen in extreme or BDSM-themed pornography and is not a common practice in mainstream sexual behavior. The word "gokkun" is derived from the Japanese verb "gokku," which means "to swallow."
