Kunko Mizuhara is 33 years old. For several years, she has been engaged in a taboo relationship with her son. Initially, they began sleeping together during her husband's absences, but recently her son's desires have intensified—he now seeks her body even when her husband is at home. He takes every opportunity, whether her husband is in the bath or briefly stepping out to the nearby store, to touch and approach her. Each time, her pussy becomes soaked with arousal. Caught in this daily cycle, she finds herself sinking deeper into her son's overwhelming desires.
