Furukawa Seiko is 30 years old. Married for 5 years. Nursery teacher. She and her husband got married when they sat next to each other at a local oden restaurant. Her husband gets bored easily, and he is dependent on her during sex, so she hardly moves. She wants to be dominated by a man more, but she can't ask her husband to do so. This time, an acquaintance of hers asked her to show him around Himeji, as a man is coming from Tokyo to do an interview. She is a serious person, so she never dreamed of having sex with him.
