Sensei arrives at the Porn Shop to be greeted by Miku, who is on probation for working at the family business. After trying to sell a hundred rubber dildos to Sensei, Maki and Makoto step in the picture. Makoto takes Miku upstairs leaving Maki and Sensei on their own. Maki takes this chance to introduce Sensei to her new acquisition, a portable glory hole that carries some memories of her husband Masahiro. The old memories take lead of the conversation as Maki remembers her adolescence and how her daughters have been growing really fast in the last months, remembering the last incident with Miku. The conversation takes a sharp turn when Maki asks Sensei about how he lost her virginity. Unable to answer or hide his disconfort, Maki notices she has touched on a sensitive subject and decides to go in a car ride together.
