Tired of a sexless marriage, Mayumi accepts one condom and spends the night at an adult college student's home. They use it and finish their first round early, but one ejaculation is not enough for him, and she allows him to fuck her raw. They agree to pretend the second round never happened, yet neither can forget the pleasure. With her departure time approaching, they give in once more as she rides him with her huge tits bouncing, ultimately accepting two real creampies during the stay.
