A girl with a red dot "Yumeru" born in a house of sex-starved men. - She spent her days immersed in incest with her father, who was a rope master and liked to drink urine, and her unequaled uncle who was required to have a body on behalf of her unequaled uncle. Yume grew up in a distorted family environment. She herself had grown into a perverted girl who was happy to be asked for her body and teased. This is a record of the daily life of a perverted girl who drowns in incest.
