Kumiko's older sister, Honoka, who had emigrated to Brazil after an international marriage, had returned home when Kumiko and her husband, Horio, were entrusted with their parents' absence while they were away on a trip abroad. Horio was fascinated by Honoka's body while glancing at her sisters who were delighted to see her again after a long time. Honoka, who had become accustomed to her local life, didn't care about her sleeping girlfriend, Kumiko and his wife, and she was indulging in her masturbation with a loud voice at night. When she happened to see Horio passing by, she attacked him without hesitation, ignoring her restraints and making him pour sperm into her vagina. After that, she attacked Horio many times while looking for Kumiko's openings. She squeezes her sperm with her obscene limbs and brilliant techniques.
