Ok so it’s a difficult read but it makes for some interesting points with a theory that Bukkake is a sort of ritualized human sacrifice. Take a look at this – “According to a myth of unknown origin, and almost universally disputed authenticity, bukkake was a form of punishment in feudal Japan intended to punish women caught in adulterous affairs, such that every man in the community or village would then consecutively ejaculate on her. However, most sources point to bukkake as emerging in Japanese pornography at the end of the 1980s and early 1990s. Nonetheless, the purpose is still ostensibly humiliation, punishing minor adultery with what can only be perceived as extreme adultery. Yet, perhaps there is more to the practice than simple humiliation, as erotic humiliation need not involve such a large, and importantly, communal effort.”
