Trapped in a sexless marriage, 30-year-old wife Mai volunteers to spend the night at an adult college student's home with only one condom. They use it for their first round, but the man is not satisfied after cumming once, and she agrees to sex without protection. They pretend the second encounter never happened, yet neither can forget the raw pleasure. With her departure time approaching, they give in again, and the H-cup wife rides him into repeated orgasms while allowing two creampies during the night.
