Mai, a married woman who applied due to a lack of sex with her husband, is given a condom and spends a night at a college student's house. They finish sex quickly with the condom, but the man, unsatisfied with just one ejaculation, convinces her to have sex without it. Although they pretend the second encounter never happened, the intense pleasure of raw sex proves too tempting, and they find themselves seeking each other out again as their return time approaches.
