A married woman who works as a librarian and a female college student who met at a university library. The female college student invites the married woman to her home. When the married woman goes to visit the female college student's house, she is suddenly kissed by the female college student in the elevator, and in the room she is stripped naked and caressed all over her body. Although she is confused by the sudden change in the female college student, she cannot resist the pleasure. The two, captivated by pleasure, caress each other's genitals in the bath and in bed, devouring each other with a double-headed dildo and a strap-on. Then, as the night draws to a close, the two bid farewell with a vibrator and a sweet kiss.
