JUR-310 A married sports instructor with a beautiful brown-toned figure and shapely hips who leaves a middle-aged man completely drained. Kana Miyashita

Kana, a married woman working as an instructor at a gym in a rural town, had a cold and distant relationship with her husband, though she kept that fact hidden from the local community. Then, through an introduction from another married woman, a middle-aged man named Ippei begins attending the gym. As Kana continues to train him day by day, she becomes drawn to Ippei and starts to tempt him with her toned physique. Caught up in a secret affair unfolding within the town, Kana and Ippei are overcome by a sense of guilt and gradually become more deeply involved.
