A strange man appears before a woman who has lost her memory. Though he inexplicably takes care of her daily needs, she feels uneasy about his kindness. Gradually, however, she begins to open up to him. Fully accepting him in her heart, she surrenders her body and immerses herself in sex, obediently fulfilling his desires. As days pass, his demands grow increasingly extreme—deep-throat gagging, choking during doggystyle, creampie after creampie with violent thrusts bending her into a shrimp-like arch. Manipulated and brainwashed, stripped of her past and memories, she drowns in pleasure, surrendering completely as his sex slave.
