Erena Honjo, a married woman who met her partner through social media, participates in this documentary to explore her deep-seated masochistic desires. As she grows closer to him, she progressively reveals more of herself. A massive milking session takes place inside a moving car, serving as a test of her physical endurance and submission. At a restaurant, she is tormented with fingers, struggling to maintain composure—an agonizing display that leaves viewers trembling. Outdoors, enemas and humiliating defecation symbolize her complete transformation into a submissive sow, with no mercy shown. Through this documentary, the hidden depths of Erena's masochism are gradually exposed.
