Makoto, the older sister, and Miki, the younger sister, have come to know the bottomless pleasure that can only be experienced between women... They look at each other and kiss each other passionately until they are covered in saliva. They lick each other's sensitive body from corner to corner. They come, come, come, and are made to come. Once they get to know each other's sexual acts, they can't stop. A secret relationship that no one is allowed to know about.
