This time, the much-requested Nao Mizuki returns to the series! The new teacher, Mizuki-sensei, is worried about Shota, who has stopped going to school due to bullying, so she visits his home. When she talks to Shota's father, she learns that he became a hikikomori because he was bullied in a single-parent household... Nao sympathetically encourages Shota by saying, "Tell me anything you can." Shota buries his face in the teacher's large breasts while crying, and a grin appears on his face... Nao Mizuki Nao has become even more erotic, and Shota's pranks have her panties soaked!
