Satomi marries a deeply submissive husband, but she is just as masochistic and her cravings keep building. Her sadistic father-in-law sees through her and begins bondage training her in front of her husband. Rough rope digs into her voluptuous body as she is tied down and made to cum repeatedly, then her father-in-law's massive cock makes her climax. She eagerly cums while her husband's coworkers take turns fucking her, and her cuckolded husband gets so turned on that he joins their attempt to impregnate her with creampies.
