Kanna Shinozaki, a voluptuous married woman with big tits, becomes aware that she is being trained in a master-slave relationship defined as "human and pig" after beginning a physical affair with her husband's coworker. On this day, another man from her husband's workplace arrives—someone who has been suffering workplace harassment. Kanna is already bound with rope, a vibrator embedded deep in her sopping wet pussy, her groin soaked and restrained. The vibrator, fitted with fresh batteries that morning, has begun to weaken as the power drains, causing her to climax repeatedly—her panties soaked through with proof of her arousal. The man, releasing his work-related stress, treats Kanna like a toy and livestock, forcing deep throat and tormenting her with sex toys. Then, another employee who resents Kanna's husband appears. He begins his revenge by making her let him lick her sweaty armpits and tongue her anus. Without using contraception, he thrusts his cock into her pussy, joining the other man in assaulting her vaginal depths with two thick shafts. Their pent-up cum erupts over Kanna's full G-cup breasts and sweat-drenched face. In that moment, Kanna is once again enveloped in overwhelming pleasure.
