Arisa married her husband two years ago and lives with her son-in-law Taichi and her family of three. One day Taichi brings two friends to his house. Arisa's friends notice her beauty and threaten her, saying, "Is it okay for Taichi to be bullied?" Two people who got a taste of the act will come to attack Arisa again at a later date. Then, Taichi, who was there, was tied up, and Arisa was naked in front of him.
