Megumi, a 29-year-old married woman frustrated by her sexless marriage, spends the night at an adult college student's home with a single condom. They quickly use it for their first round, but one ejaculation is not enough for him, and she allows him to fuck her bare. They agree to pretend the second round never happened, yet neither can forget the raw pleasure. As the time for her to leave approaches, they give in once more, leaving her with two creampies during the stay.
