Six years have passed since Juri married her husband. She used to play with her in bondage play, but it's been a while since she was tired from her husband's work. One day, Akari took out her restraints and put them on to take care of her, but since she hadn't used them for a long time, he couldn't unlock her and had to remove her restraints. It's gone. She also called her husband to ask for help, but he ignored her and she ended up crying and calling a locksmith. A locksmith man comes to her house, sees the restraints on her, and the electric massager on her desk, and rapes her, unable to move. At first, Akari resisted, but the pleasure of the restraint play for the first time in a while led her to invite her locksmith man into her house over and over again.
