Natsume, a female college student, starts working part-time at the convenience store where Tomomi, a married woman, works. Tomomi likes Natsume at first sight and invites her to her home. Nao, a female college student who visits Natsume's room without knowing anything, is suddenly kissed by the married woman in the elevator. He puts his hand inside her panties and makes her lick her genitals. Although Nao is confused by the sudden change in the married woman, she cannot resist the pleasure. Enthralled by the pleasure, the two caress each other's whole bodies in the room and devour 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.
