Sumire, a married woman who applied due to lack of sex between her husband and wife, was given a condom and decided to spend the night at a university student's house. She quickly finishes sex using a rubber band, but the man is not satisfied with ejaculating once, so she allows him to have sex without a rubber band. The two decide to pretend that the second time they had sex never happened, but they can't forget the raw pleasure, and as the time approaches for them to go home, they seek each other out again.
