Five years into her marriage, Yui, a black-haired short-haired widow, is forced into profound emotional and physical changes after her husband's sudden death. To support herself, she begins working part-time, giving her the first chance in a while to interact with men. What starts as gentle kissing gradually awakens her body, drawing her toward his large cock. Her intense blowjob techniques bring him immense pleasure, while also becoming a new discovery for her. Continuous thrusting during bareback penetration pushes her body repeatedly to climax, and the story concludes with a creampie shot deep into her womb.
