In her dreams, Riku is repeatedly violated by a mysterious man, brought to climax over and over with electric vibrators and dildos, and creampied while a black man chokes her. Unable to comprehend the meaning of the dream, she spends an unsettling day before returning home. Trying to focus on studying, she collapses from exhaustion into sleep—only to be pulled into another nightmare. When she opens her eyes, three black men are standing over her, restraining her limbs and subjecting her to relentless stimulation with massive black cocks. One after another, they creampie her, then bind her with chains and hang her upside down, assaulting her with intense vibrator torture before submerging her underwater. The overwhelming pleasure and terror experienced in the dream leave a deep, lasting impact on her mind and body upon waking.
