Unlike her usual timid self, Amu moans at full volume and cums again and again on aphrodisiacs. Men dose her, then relentlessly work her erogenous zones while her body burns. They add more aphrodisiac in every scene until she grows hypersensitive, then give her the hardest pounding of her titles so far. Her sensitivity explodes, she cums nonstop, and by the end of this film she is hooked on the drug.
