Bukkake is a group sex practice seen in pornography where a series
of men take turns to ejaculate on a kneeling recipient. At the end of
the process, the recipient may drink the semen. Bukkake is a Japanese
invention, credited to adult filmmaker Kazuhiko Matsumoto in 1998. Bukkake
originally became a porn trend because of the mandatory porn mosaic
in Japan. Since the directors could not show penetration they had to
figure out new, visually appealing ways to approach sex acts that would
satisfy the audience without violating Japanese law. Bukkake is not
and never has been confined to pornography. Some women have gone public
regarding their sexual enjoyment of bukkake; one prominent example is
Catherine Millet. This is a potentially unsafe practice; see bukkake
