Ito and Azusa were best friends. "Azusa...? That's the old school building, there shouldn't be anything there, so why...?" I followed Azusa as she was heading somewhere in secret...and what caught my eye was the sight of her and her homeroom teacher getting all horny! Rui, who found out about their relationship, was shocked by the sight and ran away, but...? Rui Hiiragi's first lesbian challenge. Bonus footage: Includes a thrilling first kiss interview before filming!
