These two couples are still on good terms even after a few years of marriage, and have a decent amount of sexual intercourse. However, they are worried that their husbands have premature ejaculations and come too quickly. We asked these frustrated wives to take on a challenge: if their husbands can hold out for 60 minutes without ejaculating during the 10-minute period, they will receive a prize of 100,000 yen! We secretly filmed the entire challenge, without the husbands knowing. Will they succeed?
