The story is set in the Taisho era. Due to an anachronism, the village has lewd customs that are unthinkable today. One poor village girl, shunned by her neighbors as an unclean child, desperately tries to avoid being expelled from the village. One day, she is chosen as a sexual sacrifice to end her starving and impoverished situation. The men always want to feast on her voluptuous body... With this in mind, they come up with an ancient ritual to turn her into a sex slave. Wanting to avoid being ostracized by the village, the naive and obedient village girl spends her days sexually servicing the filthy villagers' penises. She is gang-raped, made to squirt with pleasure, and in an otherworldly world, men devour her one after the other, devouring her to the fullest extent of their sexual desires. No one helps her, but this is the sad reality: if she doesn't mate, she will no longer be able to enter the village. However, the village girl becomes increasingly lewd, and the scene becomes a daily routine, until her presence becomes indispensable...
