Original title: お灸快楽 若草いぶり

Directed by Kuninori Yamazaki

Yomogi runs an moxibustion clinic called "Yaito-ya." She first experienced that sensation—a mix of shame, pain, and pleasure—when her father's new wife applied moxibustion to her. Since then, that humiliation has become essential to satisfying her sexual desires... and she continues to spend her days chasing after that very pleasure.
