"I'm the type of person who can't rest until I've experienced everything..."Ritsuko Sekimoto, 48 years old. She is currently a picture book author for children and has been married for 20 years. After graduating from art school, she got a job at a design company. After getting married, Ritsuko chose to become a picture book author so that she could work while raising her child. However, there is a big gap between her ideal and reality... "I knew that raising a child would be difficult, but when I'm working on my creative activities, I'm so busy every day that I don't realize how short a day is." When she gets to work, there are days when she doesn't see her husband for two or three days. Naturally, the opportunities to have sex at night decrease... "At times like that, masturbating while watching adult videos is a quick way to relieve my sexual desire." Ritsuko wants to take this opportunity to try something she normally can't do. The fantasies unique to a writer explode, showing her true nature as an adult woman who is not for children!
