One night, when her husband invited his boss over to their home, she found herself caught in an unimaginable situation. As her husband gradually got drunk and passed out, the boss began moving closer to her. In the kitchen, he started groping her body while exchanging suggestive words. She pleaded, "My husband is here, please, stop..."—but those words were merely an act. Her vagina made wet, squelching sounds under his skilled fingers, her willpower crumbling fast. Even if she tried to suppress her moans, her body betrayed her desire, and eventually she was taken into another room. What she whispered was, "I want to be tied up..." That single sentence would drastically change her fate. Her affair with the boss soon evolves into a profound trial that will test her completely.
