21-year-old flower shop employee Kana is brought in after being scouted as a parts model. At first, she lives an ordinary life, exuding a pure and gentle demeanor. But gradually, things begin to change, and she starts noticing something strange about the situation. She spreads her legs wide, shyly revealing her pubic hair through her underwear as she's made to pose. Though surprised when a large cock is thrust toward her, she eagerly takes it into her mouth, becoming so engrossed that she ends up giving a blowjob leading to an in-mouth cumshot. Before she realizes it, she's drooling uncontrollably while using her tongue to suck directly at the urethra. Her true nature is exposed—her deep love for cock becomes undeniable. Like a woman possessed, she orgasms repeatedly, losing the ability to speak properly. The sight of her gasping in overwhelming pleasure is a far cry from the demure girl she appeared to be at the beginning.
