Office lady Ryo, tormented by guilt over her affair with her section chief, found herself increasingly desiring punishment. It was then she met Ichijo, a man renowned as the perfect trainer. His methods involved unimaginable pleasure torture, so intense they obliterated all rational thought. The humiliating games within the office surpassed all decency, driving her into a state of blissful surrender. Fully trained even anally, Ryo adopted absolute obedience to every command, transforming completely into Ichijo's sex slave.
