Under the cover of darkness, a blindfolded young woman is led into a dimly lit room. Her heart races as she feels the rough grip on her arm, guiding her towards an unfamiliar sensation. Suddenly, the blindfold is pulled away, revealing her brother standing before her, fully erect. In a stroke of sick twisted fate, he has decided to take advantage of her trust and their unique situation. As she gasps in shock, he roughly pushes her onto the bed, climbing on top of her. His thrusts are aggressive and unrelenting, filling her with his warm seed over and over again. She cries out in pain and confusion, feeling both violated and ashamed, but also aroused by the taboo act they're committing. Throughout it all, her brother continues to take advantage of his sister, their bond now forever tainted by this act of depravity leaving her feeling betrayed and disturbed.
