Six years have passed since Juri married her husband. I used to play with her in restraints, but it's been a while since I was tired from my husband's work. One day, Akari took out the restraints and put them on for the first time in a while to take care of herself, but since she hadn't used them for a long time, she couldn't unlock the restraints and couldn't take them off. I called my husband to ask about it, but he ignored me so I had to call a locksmith. A locksmith man comes to Akari's house and when he sees Akari in restraints and an electric massager on the desk, he rapes Akari who can't move. At first, Akari resisted, but the pleasure of restraint play for the first time in a while led her to invite the locksmith man into her house over and over again.
