Emi Fukatsu suffers from stress and sexual frustration while her husband is away for work. Unable to control her desires, she resorts to masturbation—until one day, her father-in-law accidentally catches her in the act. From that moment, Emi is seduced by her father-in-law and forced into creampie sex. She is then made to urinate by her brother-in-law and dominated like a sex slave by her older brother-in-law, enduring increasingly harsh treatment. As her father-in-law declares, "Emi, you've been holding back for a while now, haven't you! I'm coming inside!" she pleads, "Please don't cum inside! Father-in-law!" Her helpless surrender to overwhelming desire unfolds before your eyes. [Note: Minor visual and audio distortions may occur]
