My father is a long-haul truck driver who loves drinking but can't indulge during workdays. On his days off, he drinks from morning till night to relieve work-related stress. A few years ago, my mom suddenly left home due to domestic violence, forcing them to split up. Since then, my father lived alone—until one day, Kaori suddenly showed up. She was a stunning woman with a deep cleavage, a voluptuous backside, and a faint trace of perfume lingering around her. She was far too attractive for my father, but he was away on a business trip to Kyushu. Kaori stayed at his place, and an unusual cohabitation began between us. Gradually, the relationship between my father and Kaori grew deeper.
