A young career woman working at a renowned corporation in Otemachi, Tokyo, the heart of Japan's economic district. Outwardly, she appears to be an excellent employee, skillfully managing multiple subordinates. However, behind this facade lies a deeply hidden, deviant desire unknown to anyone: a daily obsession with fantasizing about being relentlessly fucked by a perpetually erect cock, penetrated over and over without mercy, like nothing more than a mere fuckdoll. To relieve work-related stress, she repeatedly masturbates—not only at home but even in the office restroom—using her fingers to stimulate her clitoris and vagina. This work is a realistic documentary-style portrayal of her secret desires, drawing out her primal instincts through refined training and fulfilling her craving for degrading, humiliating sex.
