Makiko (33) is a married woman in her 11th year of marriage. Having always been attracted to older men, she married a man 10 years her senior. After marriage, she lived overseas for nine years due to her husband's transfer, returning home two years ago. Since then, she has been living a sexless life. Her days have grown monotonous, leaving her feeling disconnected from society. To preserve her sense of femininity, she decides to embark on a journey of infidelity. Burdened with pent-up desire, her body constantly reacts. She writhes with pleasure, moaning loudly, inviting complete domination. When fully penetrated, she gasps and moans, crying out each time her buttocks are slapped from behind, engulfed in ultimate ecstasy. Her appearance embodies a deep, desperate longing for what she truly craves.
