A female college student starts a part-time job at a beef bowl restaurant where a beautiful and seductive married woman named Chihiro works... The female college student becomes friends with the married woman and invites her 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 whole bodies in bed, devouring each other with a double-headed dildo and a strap-on. Then, as the night draws on, the two bid farewell with a vibrator and a sweet kiss.
