Kouka became an AV model at her husband's suggestion. This shoot includes extreme and taboo content she has never experienced before: natural defecation, anal training, massive enemas, feces smearing, anal intercourse, and urine drinking. Though she participates in the filming with the mindset of "if it's my husband's order," she experiences a whirlwind of emotions—confusion, shock, humiliation, and resignation—yet ultimately finds herself led toward pleasure. This work presents a series of erotic scenes depicting her inner transformation and unwavering loyalty to her husband.
