Akito and Ruriko have been married for five years. One day, Akito brought a flyer for a chiropractic clinic to Ruriko, who was suffering from stiff shoulders. Ruriko, who went to her manipulative clinic under the escort of her Akito on a holiday, felt that she was touched by a man other than her husband for the first time. Her manipulative teacher Oki, who noticed such a change in Ruriko, will play with Ruriko's aching dick in the second medical examination. Ruriko who feels that she should stop seeing her, but she is drowning in Oki's meat stick. Akito also begins to feel uncomfortable with the two of them.
