The unemployed brother-in-law, who has to stay at home all day and live off others, is always blamed by the family, but Asuka Nakama is not like that; every time she sees him sad, she always comforts and encourages him to try harder. Living at home with his sister-in-law, he frequently watches Asuka doing housework, with her body curves and her incredibly seductive posture, as well as scenes of Asuka making love with her husband, but having to resort to masturbation in the bathroom due to lack of satisfaction has made him think about helping Asuka, because she is very kind to him.
