Machi, the youngest of three siblings. The siblings living happily under one roof had a secret they could never tell anyone. The dominant older brother devours his sister's body almost every day, and the masochistic second brother even gets erect at the sight of "Machi"... One day, "Machi" is fucked with the older brother's big dick, and another day she seduces her second brother and plays pranks on his dick. This is a record of the daily lives of these lewd three siblings where incest is taken for granted...
