Newlywed Mina suddenly discovers one day that she owes a debt to a wealthy classmate. In exchange for wiping the debt clean, the classmate presents an extreme condition: "Work as my maid for three days." Arriving at his spacious mansion, Mina is forced into increasingly intense tasks—bathing his body, assisting him with masturbation, and escalating demands. Eventually, she is ordered to take creampie after creampie. Though initially resistant, Mina gradually succumbs to the pleasure upon feeling her 'master's' bare cock. Telling herself it's all for her beloved husband's sake, she numbs her mind and accepts unlimited creampie loads over and over. Her plight paints a heartbreaking drama caught between pure love and overwhelming desire.
