A young wife, Umi, wishes to conceive her beloved husband's child. However, standing in her way is the demand of her perverted husband, who has a "cuckolding fetish." Reluctantly accepting another man's dick just once, the situation spirals into an unexpected turn. Before she knows it, Umi is surrounded by a crowd of men, each pressing her for creampie sex one after another. Though she hates it, she continues to endure unwanted creampies out of a desperate fear of being disliked by her beloved husband. Assailing her are elite males who unleash impregnation-grade seed capable of guaranteeing pregnancy with a single shot—the "Strongest Impregnation Syndicate." These uniquely eccentric, intensely virile men engage in one-on-one instinctual breeding sex. Pressured with genuine intent to impregnate, relentlessly tormented with pregnancy dirty talk, and captured in raw, uncut scenes that linger on the aftermath of draining every drop of seed deep in her womb, the vivid spectacle unfolds continuously. Though Umi prays never to conceive by anyone other than her husband, she cannot escape the chain of genuine, literal creampie intercourse that tramples that wish. Everyone is serious—literally serious—about putting a woman in a bind. You will witness such an intense, dense moment firsthand.
