Okinari no suke, who was born from the sympathy for his brother-in-law - Kasumi oriho

A couple living together with their brother-in-law in a two-family house left by their parents. However, the relationship between his brother-in-law and his wife Eko had just left the house this morning. He was a wife of his brother-in-law, oruho who took care of his younger brother-in-law and burned it. Shinji was deeply attracted to his kindness, and he held her unconsciously. Although he is desperately persuaded, he loses to the frustration of his brother-in-law and forgives him. Since then, the body of Oriho, who remembered his vengeful agitation, has been unable to stop the sweet whistle that resonates with the uterus.
