My father-in-law, who was the top of a large company, died suddenly, and my husband became the president as a successor. Her wife, Shiori, hurts her heart when she sees her suffering from pressure. At that time, she is told by her secretary, Saito, that her husband has made a serious mistake. He offers an exchange condition to Kina who asks for her help. In order to help her beloved husband, Kana offered her body while trembling with her embarrassment. Shiori tells herself that it's for her husband, but her body asks for his caress and she unconsciously shakes her hips.
