Saki, a maid belonging to a drug syndicate, was repeatedly used to test the potency of aphrodisiacs, eventually becoming addicted. Her body grew constantly wet, transforming into a fully erotic state where sex triggers full-body convulsions, squirting, and drooling. Her hypersensitive body is mercilessly assaulted daily by cruel, relentless cock, enduring endless high-speed thrusting. Now unable to move without the drug, Saki continues living as an obedient maid, dependent on the very poison that controls her.
