Airi Takasaka was once a promiscuous gyaru who indulged in indiscriminate sex, but now leads a more settled life. Outwardly demure, she secretly gets wet and shows off an embarrassingly erotic expression. Her charm lies in the fusion of hospitality skills and wildly perverted sex techniques honed during nine years as a mistress. Drawing from her past relationships, she expertly uses every trick to satisfy her partner. There's just one thing left undone—violating every single hole while blushing shyly, delivering the ultimate pleasure.
