Nanako, despite her delicate and innocent appearance, harbors deep-rooted masochism and perverted sexual desires. She insists, "I just wanted to look cute. I never thought I'd want to have sex with an older man," yet in reality, she's been addicted to deviant masturbation since puberty—a history spanning over a decade. Her perverse masturbation isn't merely about the act itself, but a process of placing herself into the state of a "ravaged, cute (and pitiful) girl." During training, it's crucial to follow her fundamental desires. After arriving at the meeting spot, having carefully prepared her makeup and outfit to appear as the ideal girl, she's fitted with a gag and masked, then forced to walk through the streets. In the hotel courtyard, she takes a middle-aged man's cock into her mouth, swallowing his foul saliva and spitting it into a phlegm cup. On the entryway floor, she's made to crawl on all fours, fed from a dish placed on the genkan while a dildo violates her anus and her belly is stomped underfoot. Even after such brutal degradation, Nanako's face wears a seductive, ecstatic expression. After making her climax with oral sex while keeping an ultra-thick vibrator stuffed in her ass, she's doused with urine over her immature body, then forced to lick the cock with her tongue—finally satisfying Nanako's insatiable craving for abuse.
