49-year-old Ritsuko (pseudonym) works as a nurse at a hospital, where she finds herself reaffirming "I'm still a woman" through the daily act of manually stimulating male patients' genitals. Following in her mother's footsteps, Ritsuko pursued a nursing career, grew close to patients while working, and married at 25. She left the profession after becoming pregnant and spent years working at her husband's family fruit orchard. After 15 years of marriage, infidelity led to divorce, and for nearly a decade afterward, she had no contact with men. However, upon returning to work as a nurse, she's desired by a young male patient, awakening her femininity after years of dormancy and allowing her to accept his penis. In that moment, her nipples harden and she writhes in overwhelming pleasure. On a private hot spring trip together, they unleash their passions on each other's bodies, drowning in ecstasy.
