Kyoko, a 38-year-old married woman frustrated by a sexless marriage, is given one condom before spending the night at an adult college student's home. They quickly use it for their first round, but when one ejaculation fails to satisfy him, she agrees to sex without protection. They try to pretend the second encounter never happened, yet neither can forget the raw pleasure. With her departure time approaching, they give in once more, and the beautiful wife slowly drains him in cowgirl while accepting a second real creampie.
