Returning home for her half-brother's funeral, Rei is taken in by her stepfather, who, consumed by grief, sexually assaults her. Gradually, she is reduced to the role of her stepfather's "pet dog," psychologically broken and driven to the depths of despair. This work is part of a special project presented by the new label Global Media Light, featuring an excerpt from the first half of "Stepfather's Pet Dog: Bound Stepdaughter (RBD-36)." Available at an affordable price for a single-part release, this film focuses on Rei's suffering and the disturbing evolution of her relationship with her stepfather.
