One day, Yuji, who was invited to his boss's house, had no experience with women and was so nervous that he couldn't handle Yurie, a married woman. Yurie teases him with adult sex appeal. That night, he stays at the Matsushima family, but Yuji is so frustrated that he can't sleep. Then, Yurie, who was not satisfied with her husband's work, came over at night. Yurie gropes her body as if playing with Yuji, who pretends to be asleep in a hurry.
