Aino (28) is a housewife in her second year of marriage, living without children. After a long period of cohabitation, the couple has grown indifferent toward each other, leaving their relationship on the verge of collapse. It's been two months since they last had sex, and she feels increasingly unsatisfied with her marital life. To justify her actions, she keeps repeating the excuse she knows all too well—that their schedules simply don't match. Her desires as a woman remain unfulfilled, and the thought of dating a stranger excites her. During a hot spring trip, she gradually opens up to the man. She lovingly takes his cock deep into her throat, performs cowgirl position with vigorous hip movements, and writhes in ecstasy. Upon reaching climax, she reaffirms her identity as a woman, wearing a deeply satisfied expression.
