Yuri is a married woman who works part-time at a family restaurant. Late at night, she is suddenly embraced by a young male college student who is on the same shift as her... Although she verbally refuses, she is in a slump with her husband. Her body is receptive to the young body she has not seen in a long time. The restaurant is ordered to close early after a shortened business day, and the two of them make out in the empty restaurant for just a short time before the last train. Even though she has a husband, she continues to have an affair with him on the next day and the day after, and even accepts him cumming inside her.
