bukkake.....is an ancient japanese form of punishment for women.
when a woman in a town or village was found guilty of adultery or similar type offense she was taken to a central place locally and whilst on her knees or haunches all the men of the said town or village were then obliged tostep forward and ejaculate on her face/head, when this was complete she was then urinated on by the same males...many of which you must understand would be relatives...the urination complete she would then be beheaded.
it was a sort of humiliation b/4 death
unbelievable i hear some of you say...well in the west at the same time they burt witches and heretics, and even today many adulterers..among others , are stoned to death
