Machi is the youngest of three siblings. Brothers and sisters living together under one roof have a secret that they can never tell anyone. The sadistic eldest brother devours his sister's body almost every day, and the supermasochistic second brother gets an erection in such a "town" appearance... One day he is squid by his eldest brother's decachin, and another day he seduces his second brother and mischiefs with Ji Po "Machi". This is a day-to-day record of three obscene brothers and sisters who blended into everyday life as if sibling incest was commonplace.
