Iroha felt suffocated by her husband’s restrictions… She had been married to her husband for seven years. Although they were not blessed with children, the couple lived a relatively happy life. However, about two years ago, her husband, who had been stressed out by the fight for promotion at work, gradually began to restrict Iroha. Because of this, Iroha was forced to quit her job and became a full-time housewife. She was also forbidden from going out, and the only way to relax was to go out during the day when her husband was at work. One day, when she was complaining about her family life to a junior colleague, he pulled out her true feelings. She felt stressed by her husband’s restrictions, but she didn’t want to get divorced… but… she would feel suffocated if things continued like this. Yes… Iroha was looking for “convenient play.” At that time, Iroha learned that recently, “the number of women who want to be tied up is increasing.” Pushed by her junior colleague, Iroha wanted to take a step into an unknown world, even though she was reluctant to leave due to a sense of guilt. A new world awaits Iroha there… Iroha, who had suffered under bondage, is able to release a new sexuality that she had never known before by being tied up.
