This work compiles various episodes submitted to the SM magazine "Mania Club." It tells a shockingly realistic story from the perspective of Yukiko (pseudonym), a 28-year-old married woman, recounting her personal experiences. Three years into her marriage, Yukiko had chosen to remain a virgin due to childhood trauma caused by a man, and thus had never even masturbated. She lived without any sexual knowledge beyond her marital relations. However, her husband's sexual desires were far from ordinary. His demands gradually escalated, transforming their marriage into something far removed from a normal relationship. Now, she is forced to be lent out to other men, living daily in the liminal space between suffering and pleasure. On the eve of being lent out for training, she is locked naked in a cage and forced to become aroused like a female dog through degrading commands. In Scene 1, waking up inside the cage, she finds herself grabbing the vibrator and beginning to masturbate involuntarily. The entire act is recorded by a fixed camera, and her reaction upon watching the footage later is easy to imagine. Even urination must be done using a dog toilet. In Scene 2, on the balcony of the cage room, she undergoes genital inspection by her master. Despite trying to suppress herself to avoid neighbors hearing, her loud moans prove impossible to contain. In Scene 3, during a loaned training session accompanied by her master, she is subjected to anal play by an anal fetishist who skillfully stretches her. The depiction of her anus progressively widening is intensely arousing.
