The thing that arrived from her husband who was on a business trip to Chiaki's wife, who has a glossy body, was a sailor suit. She is looking forward to playing with her husband, who is coming home soon, and when she tries it on, her next-door son, Satoru, visits. Satoru is excited by the lewd sailor uniform of a mature married woman. Chiaki, who surrenders herself to Satoru's act from her strong sexual desire, opens her mature man and sticks out his big butt and rejoices at fellowship with Satoru!
