Misaki, a married woman who responded to an ad about sexless marriages, was given one condom and spent the night at a college student's place. She quickly used the condom to finish having sex, but the man wasn't satisfied with just one orgasm, so she allowed sex without a condom. The second time they had sex, they agreed to act as if it never happened, but the real sensation was unforgettable. As the time to return home approached, they found themselves seeking each other again.
