It has been several years since Maki Hoshikawa joined her new family as a stepchild, and her everyday life has since been ruled by sexual violence. She is routinely abused by her father and brother, who penetrate her and cum inside her on a daily basis. Her sister also uses her like a licking dog, making her perform oral service instead of masturbating herself. Maki has continued to cry over her family's abuse, but deep down, she harbors a true masochistic nature—so much so that she has begun to take pleasure in her own suffering.
