At her high school reunion after twenty years, Mina receives confessions from Takuya and Shinji. With her husband away on a business trip, she invites both men over for dinner. When Takuya passes out from drinking too much, Mina freely indulges in bold sex with Shinji. Fantasizing about Takuya coming to her at night, she masturbates, longing to see him again. When Takuya visits once more, she lures him to bed, erotically swaying her hips as she becomes overwhelmed with pleasure.
