If her past secrets were exposed, everything would be over. Allowing her body out of necessity was the beginning of her downfall! She endures a humiliating creampie while her husband is away. Despite her resistance, Yui falls prey to the man's revenge, her body becoming nothing more than a breeding vessel filled with his seed.
