Yuka, a married woman who applied for a sexless marriage, was given a condom and decided to stay overnight at a university student's house. He quickly uses condoms to finish sex, but Yuka allows a college student who is not satisfied with just one ejaculation, and has sex without a condom. The two decide that they never had a second sex, but they can't forget the raw pleasure and end up seeking each other again as time comes nearing the time they get home.
