Ashina is an elite female department head excelling at a major advertising agency. Appointed as the new leader of the First Sales Division, she draws attention not only for her beauty and talent but also for her voluptuous, bursting big tits. Her direct superior, Section Chief "Takimoto," grows jealous of Ashina's success and, fueled by a past rejection, devises a scheme to ruin her. During a crucial business dinner with important clients, he turns her into a submissive sex slave, exposing the humiliated, degraded executive as she shamefully climaxes again and again. #ElderP
