Rie felt suffocated by her husband's control... She had been married to her husband for 17 years. They were not blessed with children, but they were living a reasonably happy life as a couple. However, a few years ago, her husband, who had been accumulating stress from the competition for promotion at his company, gradually began to control Rie. As a result, Rie was forced to quit her job and became a full-time housewife. Furthermore, she was forbidden to go out, and her only way to relieve stress was to sneak out during the day when her husband was at work. One day, while complaining about her family, a junior introduced her to a certain site. Rie felt stressed by her husband's control, but she didn't want to get divorced... but... if things continue like this, she'll suffocate. That's right... Rie was looking for "convenient play." At that time, Rie learned that "the number of women who want to be tied up is increasing." Encouraged by her junior, Rie took a step into the unknown world, even though she was drawn back by a sense of transgression. A new world was waiting for Rie there... Rie, who had been suffering from control, releases her unknown sexuality by being tied up.
