Having lost confidence as a teacher and struggling with her interactions with students, Moe visits her former homeroom teacher, the older Kameichi, seeking advice. She believed he would offer her a solution to overcome her struggles, but Kameichi isn't about to let this opportunity slip away. His lessons are always laced with sexual undertones, and what begins as science or physical education quickly evolves into expressions of desire. One extreme act follows another—deep kissing, mixed bathing—culminating in the notorious "Spirit Injection Pole," known as the ultimate form of love education. Though Moe remains innocent and pure, her charm and naivety only serve to fuel Kameichi's lust. The sight of the aging teacher violating the young, innocent girl is both lewd and strangely frustrating.
