Sumire was returning home from the supermarket to cook dinner for her family when suddenly a thief rushed up and snatched her handbag. Unfortunately for the thief, the bag contained no money or phone, only sex toys and pornographic magazines that she had bought to satisfy herself because her husband was impotent. Frustrated at not getting any money, the old, dirty thief turned back and forced Sumire to take him home. He decided to give this lascivious woman a new experience, and the naive young wife agreed to take him home and offer her tender body to the unlucky thief.
