Mayumi is a 32-year-old woman who has been given a condom at her home in an ordinary college student's house, and cannot be satisfied with the rubber cane once a night.

Mayumi, the wife of a couple who applied for sexless marriages, was given one condom and decided to stay at a college student's house. She uses rubber to get her sex done early, but for a man who is not tired of ejaculation at one time, she forgives him for having sex without rubber. Two people have never had a second sex, but they can't forget the joy of life and ask each other again as they come home on time.
