Shizuka, 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 once wasn't enough for the man, so she allowed sex without a condom. The second time they had sex, they agreed to pretend it never happened, but the real sensation was unforgettable, leading them to seek each other out again as the time to return home approached.
