"Nana", the only daughter who spends her days in incest, being asked for her body in turn by her father, who is a rope master and loves to drink urine, and her uncle, who is freeloading. Growing up in a distorted family environment, she has grown into a perverted girl who feels happy when her family asks for her body. This is a record of a family's "everyday life that is too close". Even today, "Nana" seeks the penis of a male family like a prostitute and drowns in incest.
