The female college student met Mio, a married woman whose husband is a novelist, on the campus of her university. The female college student became friendly with the married woman and invited her to her home. When the married woman went to visit the female college student's house, she was suddenly kissed by the female college student in the elevator, and in the room she was stripped naked and caressed all over her body. Although she was confused by the sudden change in the female college student, she could not resist the pleasure. The two, captivated by pleasure, caressed each other's whole bodies in bed, devouring each other with a double-headed dildo and a strap-on. Then, as the night drew on, the two bid farewell with a vibrator and a sweet kiss.
