Shiho Sakura, a married woman working at a home renovation company, finds herself in a desperate situation when her son repeatedly makes mistakes, putting his job at risk. To save him, she submits to the demands of the company president, enduring humiliation and abuse. In front of her son, she is forced to perform oral sex on the president, then bound and subjected to incestuous assault, climaxing repeatedly with creampie after creampie. At business meetings, her armpit hair and pubic mound are exposed and toyed with, her pussy violated by an oversized vibrator as she writhes in pleasure like in yoga. Under the guise of "company training," she is tied up and raped by the president. Ultimately, overwhelmed by twisted ecstasy, she weeps and cries out to her son, "Mom's a pervert, I'm sorry!" as she reaches the pinnacle of orgasmic bliss.
