Noriko is not immune to perverted things. She soon feels dizzy. She's recently got a boyfriend, Toshio, a talented doll modeler. He is gentle and kind. Yes, they are a good couple. Toshio worked at an amusement park nearby, so Noriko often visited there to give him a lunch box. In return, he gave two free tickets for the amusement park to her. "You can come with your boyfriend." "Well, I need only one..." Like this, they started dating... [From ErogeShop]
