A sensual schoolgirl gets swept up in a steamy lust triangle between her horny teacher and her kinky classmate. Tsumugi (Sora Aoi) is your typical Japanese teenager. Pretty, curious, and adventurous, she seduces her teacher Katagiri while exploring the more sordid side of sexuality with Kosuke, a classmate who likes to dabble in bondage. When both relationships become too intense to maintain, Tsumugi must make an important decision. Will she choose the flutter or first love, or the thrill of being libertinism? Featuring music by legendary Japanese punk rocker Shigeru Nakano.
