As societal trends shifted and the bubble era faded, an atmosphere of decay and stagnation began to emerge, bringing increased attention to themes like infidelity, mistresses, school uniform fetishism, and deeply private perversions. Amid this rise of extreme and abnormal content, a definitive AV masterpiece was born. This release compiles a dense digest of the six-part series "Immoral Heart" I–VI, featuring four titles: "After-School Punishment," "Idol's Sobbing," "The Lady's Betrayal," and "Humiliated Mistress ■8." Witness bestial training of beautiful, devoted housewives; documented sequences of repeated large enemas and massive defecation; chilling bullying and domestic violence against innocent uniform-clad teenage girls; and brutal, sadistic training of idols. Please note that due to master tape degradation over time, there may be minor video or audio distortions.
