Miki Sunohara works as a dentist, constantly overwhelmed by her demanding job. To relieve stress, she relies on one-time sexual encounters with men she meets through dating apps. While not every encounter is satisfying, occasionally she meets someone with perfect chemistry, leading to intensely passionate and erotic experiences. The reason lies in her marriage to a husband suffering from ED, making normal intercourse impossible. Knowing this, her husband respects her needs and permits her to have sex with other men. Recently, however, he has continued allowing it only under the condition that he can record footage of her sexual encounters.
