Office lady Yuu lived a fulfilling life with a steady job and a loving boyfriend. However, her only problem was her unpleasant neighbor. One day, the repulsive man, terrible in both appearance and behavior, suddenly broke into her apartment, and she desperately tried to resist. But his presence began to draw her in in ways she never expected. At first, she felt discomfort and revulsion, but the moment he penetrated her, something inside her began to waver. His cock was unimaginably thick, long, and hard—far closer to her ideal than that of any man she had ever known, even the one she despised most. This shocking sex would become the turning point that changed her life forever.
