Sensei's Extra Lessons ~How Babies are Made~

A young boy named Tomoya Fujimoto asks his teacher where babies come from. The teacher decides to give him a practical demonstration by visiting his house and sexually assaulting his mother in front of him, explaining the biological processes along the way. The teacher continues to assault Tomoya's mother while forcing Tomoya to watch. He explains his twisted logic about consent, hormones, and societal expectations regarding rape and marriage, attempting to brainwash the boy into accepting the situation. The assault concludes with the teacher finishing inside her.
