Takimoto, a teacher at a school in Tokyo, lives with his young wife Umi. A bright future should have been promised to the two people who lived modestly and happily. One day, a group of people who had a grudge against Takimoto kidnapped the sea, aiming to make Takimoto absent. A few days later, Takimoto received a DVD with a picture of Umi panting. Umi continued to eat vaginal cum shots and facial shots in the video, and became more and more horny.
