A documentary about men who are forbidden from ejaculating for a month, with padlocks attached to their chastity belts, in search of the "ultimate ejaculation sensation"! The men were already at their limit of endurance. The moment the chastity belts were removed, their penises began to expand. Their first ejaculations in a month released unbelievably thick semen. The satisfied expressions on the men's faces told the tale of their blissful moments. Reiko Kobayakawa's sexy, edgy play adds to the excitement.
