This is Madonna's bachelor dormitory, which is currently full. Our plump dormitory mother will take care of your cock!

While waiting for the return of her husband who was caught stealing company money, Saki begins working as a live-in dormitory mother, and although she is confused by the troubles caused by the new dormitory students, she works hard. During these busy days, her maternal instincts are tickled by the sight of Takinogawa, who is in a daze due to a cold, and Koshinzuka, who has been injured in a fight, and while apologizing to her husband in her heart, she gently guides them into her. One night, Machiya sneaks into the room where Saki is sleeping and threatens to reveal his lewd relationship with a dormitory student.
