After four years of marriage, his wife Sakura has been living a frustrated life with less nighttime activities. One day, when she visits her father-in-law's house with her husband, there is her father-in-law, who has forgotten the face of her son. Sakura is worried about her father-in-law and takes care of her, but her father-in-law asks Sakura to become a model because she started painting as a hobby. Her father-in-law is motivated by her plump hips and advances her brush, but without her knowing, her crotch stick also becomes splendid. "This is art!" My father-in-law rejoices while staring at Sakura's wet crotch. Sakura was also violently disturbed by her father-in-law's "brush".
