One day, when the Ogiya family next door, who had a constant quarrel between the couple, noticed that they were preparing to move, Ayu went out to help clean up. This is because I couldn't leave a big tree that looked good to people. However, for Oki, who was lonely after being escaped by his wife, Ayu's kindness only aroused his desire. And Oki pushes down the unsuspecting Ayu. Ayu who was disgusted by her husband accepted such a big tree, and the two began to repeat secret fornication right next to her husband.
