A pair of black electrician workers arrive at a house to fix the air conditioner. The homeowner is a demure married woman named Koyuki, with fair skin, voluptuous big breasts, and a thick, curvy lower body. As they work, the black men become increasingly interested in Koyuki’s body, unable to suppress their desire, thinking, "We have to fuck her no matter what!" Amid bizarre, almost devilish twists of fate, one day while resting in a park, the electricians suddenly spot Koyuki—the same woman who hired them—appearing before them again, her alluring figure reigniting their lustful urges.
