Boukaki is a festival, well used to be a festival in japan where a group of men (old and young alike)
will masturbate and semen onto one container. afterwards they
will pass that container full of semen (say about 500ml or more) to a girl of a legal age and she
will drink it.
yep , drink it all up in one go. The men
will cheer as she drink them and she
will probably have to compete with another semen-drinking girl nearby and the girl who wins
will be awarded with a prize!! and the prize can be anything from a cheap dildo to a penis-shaped trophy made of gold.
Now, Boukaki festivals are intertwined with the japanese communal baths, orgy and naked sports. Its a weird japanese event so to speak. I say weird because the women seems to be willing in bringing their dignity and submissiveness to a very extreme degree.
