Three couples who gave up on marriage due to financial struggles take on a daring challenge! They must perform bold, outrageous tasks—penetrating each other's genitals in front of a crowd and delivering humiliating public marriage proposals with zero privacy. If they succeed, they win 1 million yen as wedding funds, but if they're caught failing, they're immediately disqualified. Under rules that even permit creampie ejaculation, the women climax repeatedly, driven more by intense pleasure than embarrassment. Their boyfriends can't help but get aroused watching their girlfriends' passionate reactions! Some even admitted they finally felt ready to get married after such an extraordinary proposal!
