Despite being married women and genuine lesbians, Shiho and Maki Hojo had been together for two years and were beginning to feel exhausted with each other. Seeking new romance, Maki decided to break up with Shiho, but when Shiho tearfully begged her to stay, Maki came up with a cruel idea. Since Shiho said she would do anything, Maki treated her like a dog, forcing her to go on an exhibitionist walk wearing only panties and a coat. Unable to bear the humiliation, Shiho sought a new lover to get back at Maki. When Maki learned of her actions, driven by jealousy yet now in a reversed position of power, she had no choice but to submit to Shiho.
